At the beginning of August, the fruit can be collected when it changes from green to blue and black. The fruits collected were accumulated and softened, then scrubbed, rinsed with water to remove the peel and pulp, and the kernels were placed in a ventilated place to spread and dry to get pure seeds.

The loam and sandy loam with fertile soil, drainage and irrigation and convenient transportation were selected as seedling plots. Deep ploughing in autumn, turning deep 25-30cm, combined with deep ploughing per mu (667m2) of rotten farm manure 2m3, rotary ploughing crushed soil.

3. Sowing seeds

Sow seeds from late April to early May. Ridge farming, when the soil moisture is poor, first pour through the bottom water, sow in a single row along the ridge, cover the soil with thick 1.5cm, and suppress and preserve soil moisture. The sowing amount is 10g per extended rice. Keep the soil moist in the sowing layer and start to emerge 7-10 days after sowing.

4. Field management

(1) weeding by ploughing

Compared with weeds, sowing seedlings are less competitive in that year, so it is necessary to weed early and small by ploughing and weeding in time to increase soil permeability. According to the situation, it is necessary to loosen the soil and weed 4-5 times a year, and the depth of loosening soil is 2-3cm. Gramineae weeds are more thoroughly weeded with chemical herbicides such as pesticide Naapujing, Gaoke, Wanmaodi and so on.

(2) transplanting seedlings

In order to ensure that there is enough nutrition space for seedling growth, interseedling should be carried out in late June. It is required to keep 30-40 seedlings per extended rice, such as thinning, keeping large and evenly distributed. The strong seedlings can be transplanted and cultivated, and 1-2 leaves of the lower part of the seedlings should be cut off when transplanting to facilitate survival, and water should be watered thoroughly after transplanting.

From the second year after planting, the seedlings are pruned every year, and the spring pruning is carried out when the seedlings are not sprouting, all the lateral branches below 2.5m of the trunk are cut off, the cut mouth should be flat, do not hurt the trunk, leave scars, and affect the ornamental value of the seedlings. Sparse seedlings. After a few years of cultivation, when the growth space of seedlings is insufficient, the method of removing trees from separate plants can be used to sparse seedlings, and the sparse seedlings can be directly used for greening or to continue to cultivate large seedlings in different places.
