[Management and cultivation]
The cultivation of grafted seedlings of new walnut hybrid strains mainly adopts the seed method ① heat storage and moisturizing grafting method. The grafting time in Yunnan is from 1st to 2nd. The rootstock is used to sit on the ground in the garden, the scion is sealed with wax, and the head is broken and the abdomen is grafted or the skin is grafted. After connecting, wrap the interface with wet sawdust. ②Anvil-moving grafting method. Dig up the rootstock from mid-to-early January, seal the scion with wax, and graft the grafted plants. After grafting, transplant the grafted plant on the seedbed, water it thoroughly, and cover it with film. ③ Grafting of seedlings and anvils in the open field. In May, the seeds of iron walnut are used for germination in wet sand to cultivate the bud stock. The following year, from mid-to-early May, they are grafted indoors with the bud stock and transplanted to the seedbed for planting. They are then watered and covered with a film for daily management.
The density adopts the fruit-grain intercropping cultivation mode. The row spacing is ~ meters, and the plant spacing ~ meters adopts the horticultural cultivation mode. Plant-row spacing is m meters or m meters are planted sporadically on all sides. It can be adjusted flexibly according to local conditions. Generally, the plant-row spacing of m meters can be used.
Prune in a heart-shaped shape, set the trunk height, and cultivate a round-headed crown with large main branches and a heart-shaped tree. Because the new walnut hybrid strains bear fruit early and have strong side branches, the perennial fruiting mother branches should be retracted in time to increase the thickness of the fruiting branches, and diseased branches, dead branches, weak branches, crossing branches, overlapping branches, overly dense branches, drooping branches and parallel branches should be removed in time. . Short-cut branches promote strong growth, and short- and medium-length fruit-bearing branches should not be short-cut to achieve a reasonable distribution of various branches and balanced growth.
Irrigation: Because the new walnut early-fruiting hybrid strains bear fruit early and grow while bearing fruit, they consume more nutrients and must be effectively supplemented to maintain high, stable and high-quality yields. When applying additional fertilizers, a combination of organic fertilizers and chemical fertilizers must be used. Apply basal fertilizer (stable manure is best) every year from late autumn to early winter. Apply top-dressing fertilizer once a year, once a month and twice a year. For annual trees, apply kilograms of urea per plant or kilograms of compound fertilizer per plant. In the dry season, water in areas where conditions permit ~ times. < br/>Pest control The main pests that harm walnuts in Yunnan include chafers, walnut beetles, walnut borers, walnut caterpillars, etc. When serious pests occur, they will have a great impact on the growth, yield and quality of walnuts, and comprehensive prevention and control measures should be taken in a timely manner. ① Predict the occurrence of insect pests ② Strengthen the comprehensive management of the garden to promote tree health ③ Remove insect source branches in a timely manner ④ Carry out biological and chemical control. Walnut diseases are mainly root rot, which is caused by poor drainage in walnut orchards . Timely trenching and drainage during the rainy season can prevent the occurrence of root rot.
