1. Site selection: All kinds of soil can be planted in hilly and plain areas, among which drainage and irrigation are convenient, the soil is fertile, growing vigorously and the yield is high. Before planting, dig a planting ditch 50 cm deep and 60 cm wide. Spread a layer of 20cm thick straw at the bottom of the ditch, covering about 10cm topsoil. Then apply chicken manure and compound fertilizer on the topsoil, and then backfill. Covering 0.5 tons of straw, 0.5 tons of chicken manure, 50 kilograms of compound fertilizer or high-quality decomposed agricultural fertilizer 1 ton per mu,
The planting row spacing is 3m× 2m, per mu 1 1 1 plant. The row spacing of wasteland plants is 1m×2m, with 333 plants per mu. When planting, put the seedlings into the filled planting ditch, straighten out the root system and make it extend around, then cultivate the soil, step on the soil and water it once, and then spread straw or plastic film on the bottom of the tree to prevent the soil from polluting the mulberry trees.
Second, shaping and pruning: the planted seedlings should be cut dry at 20-25 cm from the ground. In that year, every plant grew 5-6 new buds. When the new bud grows to 20 cm, it can produce a large number of fruiting branches; After picking the fruit in the second year, pruning combined with shaping in summer, controlling the height of trunk, pruning many drooping branches, leaving 2-3 buds less for all fruit branches,
In order to promote the germination of new buds as fruit branches in the coming year. Short cutting should be done sooner rather than later to ensure that new buds have enough time to grow, accumulate nutrients and differentiate flower buds. Mulberry trees are cut short every year after harvest, and gradually form a low and dry tree shape. When pruning in winter, the weak branches and degenerated fruit branches germinated in summer should be shortened appropriately, and generally the top of the branch tip should be cut off by 20-25cm.
3. Pest control: The main diseases that harm mulberry are brown spot, anthracnose and powdery mildew. The main pests are geometrid, caterpillar, spider cicada, Apriona germari and so on. Every winter, the pruned litter is combined with fertilization, burning and buried deeply; Before germination, disinfect the whole branch with 3 waves of smectite sulfur mixture;
Spraying 40% omethoate 10- 15 days or dipyridamole 2000 times plus 75% thiophanate-methyl 1200 times or 75% chlorothalonil 800 times to control caterpillars, brown spot and black spot.
