Cultivated [ ]
1 biological characteristics like a warm and humid climate. Mountains and plains are planted. With rich, deep, moist clay loam better growth, can use the roadside, ditches, beside the house, slope cultivation.
2 cultivation with seed propagation. Seedling transplanting, 10-11 harvest ripe fruit, with a slightly damp sand mixing storage. 2-3 seeding, in spaced 24cm open ditch, depth of about 6cm, sowing width 9-12cm, a thin coating of fine soil, about 3cm, cover grass, germination when uncovered, encounter arid to pour water, often keep the soil moist, shallow tillage after emergence of attention to weeding, accomplish soil don, dressing two. To second years spring rains to transplant 1, prompted many fine root colonization, easy to survive, breed for two years, then colonization. Colonization in the spring rains, the spacing hole width and depth of the 2-3m, 30cm, seedling digging, cut off the long taproot and part of leaves, roots will stretch, seedling soil depth, with slightly darker than the original is appropriate, then poured water root.
3 field management after planting in a forest, a year in spring, autumn two season to the cultivating 1 times, preferably in each soil after fertilizer 1 times, and cut in addition to hinder the growth of the miscellaneous tree, preventing human and animal residues embarked, in letter to forest, i.e. without any other management.
