1. Requirements of Litchi on the Growth Environment: Litchi is a tropical plant. Litchi needs enough sunlight for its growth and development. Sunlight can promote assimilation, flower bud differentiation and fruit color and fragrance. But if the sun is too strong and the evaporation is large, the filaments will wither, the stigma will dry up and pollination will be difficult. Therefore, the sunshine duration in flowering period should be long, not too strong. During the development of young fruits, the weather should be sunny, otherwise insufficient sunshine will affect photosynthesis, resulting in malnutrition and fruit drop. It needs sunny days for the fruit to mature, otherwise the color of the fruit is not fresh, the aroma is light, the sugar content is low and the quality is poor. As the saying goes, "there are lychees in the south and longan in the north", which is a summary of fruit farmers' experience for many years. There is more sunshine in the south, southeast and southwest, which is beneficial to flower bud differentiation and good fruit quality.
Second, the planting method:
1, sowing time: Litchi seeds can be reserved for sowing every time, and the propagation time of each plant is different. Litchi can be planted in April-June in spring and August-September in autumn, because the temperature requirements in these two periods are most suitable for sowing, which can promote seeds to take root and sprout faster and grow better fruits. More delicious.
2. Choose seeds: First, you need to choose good seeds to grow litchi. You can buy fresh litchi, take the fruit out as seeds, or buy litchi stones directly. ?
3. Seed treatment: After the seeds are prepared, it is necessary to treat the seeds, wash off the pulp remaining on the seeds, and then soak them in clear water. Change the water every two days, wait for the fruit to crack and turn white, then soak for a few days, and the seeds will completely crack, which can promote litchi to take root and sprout and make it grow better.
4. Sowing method: When planting litchi, it is best to prepare a shallow basin, which can be planted in red soil, loess or purple soil. In the process of planting, water with bactericide to disinfect and prevent diseases, then sprinkle the treated fruit on the soil to keep the soil moisture, propagate in the shade, and then propagate in the sun after the fruit takes root and sprouts.
5, plastic pruning: because litchi grows very fast, it needs plastic pruning once. It can be trimmed in summer, autumn and winter. Old branches, dead branches and lateral branches of litchi need to be cut off, which can reduce the consumption of nutrients in the soil and promote the fruit to be more delicious. Otherwise, litchi will grow white, which will affect the growth of litchi and the taste of fruit will be greatly reduced.
6, watering and fertilizing: Litchi likes to grow in a humid environment, and Litchi needs a lot of fertilizer. Water every 3-5 days in spring and autumn, every morning and evening in summer and every 8- 10 day in winter. There is no need to use too much fertilizer. Compound fertilizer can be applied every other month in spring and autumn, but it is not necessary to apply fertilizer in Xia Dong.
