How to plant delicious, high-quality and high-yield litchi is what every grower expects. Xiaobian believes that the high-yield of litchi is inseparable from the irrigation of fertilizer. Mastering scientific fertilization technology is of great help to improve the economic benefits of litchi. Promote tree recovery and autumn shoot development, and lay a foundation for high yield in the coming year. Early maturing species and robust trees should be applied after fruit picking, and late maturing species, trees with many fruits and weak tree potential should be applied 10 ~ 15 days before fruit picking.
Topdressing should be carried out in the afternoon rather than at noon, preferably in the ditch. The fertilizer should not be stained with leaves. During topdressing, the fertilizer should be sprayed and watered immediately to accelerate the dissolution of fertilizer and clean the leaves. As long as the temperature is appropriate and the water quality is clean, generally, some white roots can grow at the base of cuttings after one month, and then transplant them into 10 gallon plant pots to cultivate new potted happy trees.
During the slow seedling period, pay attention to shielding the direct sunlight, and do a good job in water spraying and moisturizing. After about one month, the plant can fully survive in the pot, and then the normal maintenance and management can be restored. The top dressing amount of nitrogen fertilizer and potassium fertilizer should account for about 40% respectively. The application amount of high-quality farmyard compost and stable manure should not exceed 5000 kg per mu. The application amount of high-quality organic compound fertilizer should not exceed 100 kg per mu.
However, whether it is to make it into a Foliage potted plant or let it blossom and bear fruit, we need to raise it well. Happy tree is a kind of acid loving tree species. First of all, we need to provide it with a comfortable basin soil environment. However, the happy tree likes fertilizer but is not resistant to fertilizer, so the concentration of fertilizer must be well controlled. Do not apply concentrated fertilizer or raw fertilizer, otherwise it will cause damage to its root system.
In the growing section at the top, cut off all the formed leaves and directly put them on the pot alone. Cutting and cultivation are carried out simultaneously. After two months of cultivation, a pot of formed plants with large leaves, tight branches and short, strong and vigorous branches is formed, which is quite elegant indoors. In winter, keep its leaves dark green. Generally, spray warm water once a week. If the water level is less than 2 / 3 of the root system, always clean the inner wall of the 5 gallon nursery pots to avoid moss.
Generally, the retting organic fertilizer should only use the above liquid instead of dry matter as far as possible. If the dry matter of non rotten organic fertilizer is applied, it will ferment and heat in the soil, thus damaging the root system and breeding pests and diseases. Hole application is to dig several soil holes 30-60 cm deep around the tree crown and apply fertilizer into the holes. The method of injecting fertilizer is to drill holes in the tree tray around the trunk with a soil drill, about 50 cm deep, and inject the prepared fertilizer into the hole.
Due to the high requirements for water quality, the cutting rod of sea taro is suitable for spring, summer and autumn. When the root system grows too long and too dense, it is necessary to appropriately cut off the old roots and shorten the long roots, so as to promote the germination of new roots and enhance the root activity. After taking out the dripping Guanyin completely, you can directly use the plant pruning tool to cut off the rotten roots, and then trim all the branches and leaves of the plant, leaving only the healthy roots of the plant.
Dishui Guanyin is native to the humid tropical rain forest in Southeast Asia. It likes scattered light and doesn't like direct sunlight. It should be placed in the shade in spring and autumn, in the shade in summer and in the house in winter. The residual matrix in the cavity tray shall be removed first, then washed with clean water and dried, and then the 15 gallon pots shall be placed in a closed room, mixed with sulfur yellow powder and sawdust, and then ignited for fumigation and disinfection.
In the process of vegetable planting, the management of seedlings and effective prevention and control of diseases are very important for the growth and development of vegetables in the later stage. We must do a good job in these precautions. After the seed buds are unearthed, the seedling tray is placed on the bed surface of the seedling greenhouse. It is OK in summer. In summer, the plant is exposed to strong sunlight. After water stains appear on the leaf surface, it quickly loses water and turns gray white.
Phyllostachys pubescens belongs to foliage plants. In order to ensure leaf hypertrophy, there should be enough nutrients in the soil for its absorption, so thin fertilizer should be applied frequently. Generally, fertilize once every half a month during the growth period. Do not use raw fertilizer or thick fertilizer, which is easy to burn the root system of Phyllostachys pubescens. Fertilization should be 5cm ~ 10cm away from the root of the plant as far as possible, and should not be applied to the leaves. Astigmatism exposure in spring and autumn, the turtle backed bamboo should be maintained in the sun and can receive light all day.
Hanging bamboo plum love wet environment, now 3-6 days to water once, need regular spray moisturizing. Longtie is a plant native to the Canary Islands in the Atlantic Ocean(plastic nursery pots). The climate of this island crosses between tropical and subtropical and marine climate, and Longtie grows here. In recent years, it has been introduced and cultivated in many places in China, with a small amount in North and south.
The cold tolerance of golden diamond is poor. In the process of breeding in winter, plants with a temperature lower than 10 ℃ will enter the dormancy period. If they are in a low temperature environment for a long time, they are easy to suffer from freezing damage. Therefore, the golden diamond must be moved indoors to keep warm in winter, and the plants can survive the winter smoothly only when the indoor temperature is controlled above 5 ℃. If the growth temperature is too high or too low, it is easy to cause the leaves to turn yellow and wilt.
Reduce watering. In winter, the golden diamond enters the dormancy period. At this time, the plant will stop growing and the plant's demand for water will be reduced. At this time, we must reduce watering on the plant and ensure that the soil is in a dry state. And watering in winter should be carried out after the temperature rises at noon to avoid freezing the plants. During this period, the compound fertilizer of 20n-4.4p-16.6k was sprayed once a week on the basis of nitrogen application of 200 mg / L.
Stop fertilization. In addition to reducing the demand for water, the demand for nutrients is also reduced in winter(1 gallon nursery pots wholesale). At this time, fertilization is easy to cause fertilizer damage and burn the root of the plant. Therefore, the golden diamond must stop fertilization during the winter. Generally, it is only necessary to apply phosphorus and potassium fertilizer to the plant once before winter. When culturing Ficus Ficus with slightly acidic water quality, we must ensure that the water quality is appropriate and there is a good basic environment.
Water banyan likes to live in water with high hardness. The pH value is about 5.5 ~ 7.0. If the water quality is not guaranteed, it is easy to cause root rot. During the curing period, the water shall be changed regularly to ensure that the water quality is clean and pollution-free. The temperature is suitable. The water banyan is not cold resistant and likes a warm growth environment. The suitable growth temperature is about 22 ℃ ~ 30 ℃. Maintaining the temperature within this range can promote the good growth of the water banyan.
The growth temperature in winter should not be lower than 15 ℃, otherwise it will not survive the winter smoothly. The main application of nitrogen fertilizer if you want the water banyan to grow vigorously, nutrient is an essential condition. It is recommended to apply fertilizer solution once a month, mainly nitrogen fertilizer, to promote the root growth of water banyan. 70% of the nutrients in the water are absorbed by the roots and grandchildren, and the remaining 30% are absorbed by the branches and leaves. Therefore, during the maintenance period, there should always be sufficient nutrients in the water to be absorbed by the banyan roots.
Each flower needs different sunshine time(7 gallon pots). Generally, flowers can be divided into two categories. One is long sunshine flowers, such as claw leaf chrysanthemum, primrose, violet, Milan, hydrangea, etc., which require 14 to 16 hours of sunshine every day, otherwise they cannot bloom; The other is short sunshine flowers, such as chrysanthemum, poinsettia, crab claw orchid, etc., which can bloom only in 8 to 12 hours of sunshine, and can not bloom or delay flowering beyond 12 hours.
Many potted flowers actually like a semi cloudy environment, and it's best to have ventilation in the house. Don't let the flowers in an airless room, which will reduce the vitality of potted plants. On the contrary, take Phalaenopsis as an example. This kind of flower likes wet environment and cool places, because it grows under trees in nature. If it is taken home and exposed to the sun, it will wilt.
Lavender needs sufficient sunshine and a suitable wet environment. The environment that can give full sunshine is better. It is semi heat-resistant and cool. It likes to be warm in winter and cool in summer. In summer, it should cover at least 50% of the sunshine and increase ventilation to reduce the ambient temperature. Lavender doesn't like water retention in its roots. After the first watering, it should wait until the soil is dry. The second watering is best when the soil surface is dry, the interior is wet, and the leaves are slightly wilted.
Temperature and light management of Platycodon grandiflorum seedlings Platycodon grandiflorum mainly propagates by seeds. Its seeds are very small and belong to good light seeds. There is no need to cover the soil after sowing(2 gallon plastic pots). It is better to keep the brightness above 5000 lux. The germination rate is 80% - 90%, and the germination temperature is 15-30 ℃, 20-25 ℃ is the best. Germination will be delayed below 15 ℃, and germination is very poor above 35 ℃. In addition, the temperature should not be too high and the fertilization should be appropriate.
For the same variety, it takes only 4 months to blossom in spring sowing, while it takes 8-10 months to blossom in May September sowing. There are also great differences among different varieties. Very early-born varieties can bloom in 100-120 days in spring, while late-born varieties need 150-180 days to bloom. Some flowers cannot survive directly from the sun and need light for photosynthesis, so they can be exposed to scattered light.
Generally speaking, it is very important to adjust the harvest time according to different production cycles of varieties. The growth rate of Platycodon grandiflorum seedlings is greatly affected by temperature. It takes about 40-50 days from sowing to 4-leaf stage in summer and 80-90 days in winter. The best night temperature for seedling raising is 15-18 ℃, and the daily temperature is 20-23 ℃. Platycodon grandiflorum can also grow at night temperature of 21 ℃ and day temperature of 34 ℃, but it is prone to rosette phenomenon.
Planting in spring and autumn and winter can be grown under full light. Summer and early autumn seeding should be shaded properly. Seedlings should be kept moist during the seedling stage. Seedlings should be sprayed under intermittent spray. If seedlings are to be transplanted, they should be planted 3 months after planting for 1 months and for second pairs of leaves. × 3 cm plants were planted and slightly shaded until growth resumed(10 gallon pots for plants). Especially after flowering, the hot sunshine in summer can not be exposed.
There are many varieties of dragon iron bonsai. Some can form trees and can live for thousands of years. It likes a warm and humid environment and the sun, but it is afraid of exposure. Planting it in the yard can make it fully enjoy the sun. However, in summer, it should be noted that when it is time to shade, it should not be exposed to the sun, otherwise it is easy to get sunburned or die.
