How to grow properly?

1. The requirements and selection of orchard land require good physical properties of soil structure, deep fertile soil layer, good drainage, ventilation and water retention; low groundwater level, no waterlogging in rainy season; high humus content of cultivated layer of land, requiring content to reach 3-5%.

Second, the requirements and selection of fruit seedlings need to choose the branches of excellent mother trees as scion grafted fruit seedlings, and to be free of diseases and insect pests with soil seedlings.

III. Planting specifications: No.1 pomelo is generally planted with 50 plants per mu, with plant spacing of 3.3m × 4m, and No.2 pomelo is planted with 60 plants per mu, with plant spacing of 3.3m × 3.3m.

Four, planting time in spring and autumn is appropriate, especially in autumn. In spring, it is planted from the beginning of spring to around rain; in autumn, it is planted from mid-September to the end of October.

6. Planting: Digging up the upper soil in the nest, applying 15 kg of decomposed compost, 1.2 kg of phosphorus fertilizer and 0.6 kg of potassium fertilizer, fully mixing and stepping, and then covering a layer of fine soil. Dig a small nest in the planting nest, which should be the same size as the soil mass of the soiled seedlings, and then place the seedlings on it to make them stand upright, spread the roots, and cover with fine soil. Conditions available green manure or straw cover tree tray, maintain temperature and humidity, conducive to survival. After 20-30 days of recovery, fertilize once every 10-15 days to promote growth, pay attention to regular prevention and control of diseases and insect pests, remove adventitious buds and excessive branches in time, and cultivate good crown.
