New Planting Mulberry Management Technical Requirements
First, the new mulberry garden survival: 1 to be dried in time (15-18 cm away from the ground); 2 to righting, training cage, step-by-step; 3 pay attention to watering drought when drought.
Second, rational fertilization: The new mulberry gardens should be repeated fertilization in phases, and pay attention to nitrogen, phosphorus, potassium ratio (10:4:5), the first time after picking the core of mulberry urea 8-10 kg, compound fertilizer 20-30 Kg or P and K fertilizer 30-40 kg; the second time after the second mulberry field core picking mu 15-20 kg into the urea; the third in mid-August before the mu application of 10-12 kg of urea to promote the growth of autumn leaves In winter, a certain amount of chicken, pig, cow dung, etc. can be applied per mu.
Third, rapid development of mulberry park: new shoot length 20 cm can be the first picking the core, removed bud buds, to promote liquid bud germination, sub-head of delivery. Two to three roots per plant were selected and the first branches were developed with good growth. Excess branches are cut off, and when the cores are picked, they must be picked in batches according to the growth condition of individual shoots and buds.
The second picking of the core, when the first stem on the new shoot grows to 40 centimeters from the ground, picks up the core again, and the new sprouting leaves 4-6 shoots per plant, distributing evenly, and the branches with good growth form the second branch. Dry, cut off excess branches. If there is a shortage of plants, it is necessary to leave a branch on the adjacent mulberry without picking up the core, and to make up the sap before the second year of spring mulberry sprouts. Note that every time after picking the core, it is necessary to fertilize fertilizer in accordance with the above fertilization standards.
Fourth, mulberry weeding: artificial weeds and chemical weeding can be used. The use of chemical herbicides requires a careful selection of herbicides. Common herbicides, glyphosate or herbicides for peanuts and soybean fields can be used. When used, try not to spray onto the mulberry trees. Artificial weeds should be based on the principle of small, early, in addition to ensure that there is no weeds in mulberry fields. Wheat mulberry gardens, each line should leave 80-100 centimeters of nutrition, and to maintain nutrients without returning to the soul of wheat and weeds.
Fifth, pest control: First of all, we must strictly select the special pesticide used for mulberry, and pay attention to the purity of pesticides, to read the instructions when buying the drug. Phoxim, chlorpyrifos, chlorpyrifos, mulberry net, mulberry worm and other special pesticides for mulberry fields, can be used for mulberry fields and mulberry crops interplanting pests. Note that mulberry gardens strictly prohibit the use of pyrethroids, organic nitrogen, and biological pesticides (the winter of mulberry dormancy can be used to seal garden pests). Prevention and treatment of mulberry disease, optional copper sulfate, oxytetracycline for agriculture, agricultural streptomycin, mycelial blessing.
Sixth, mulberry irrigation and drainage: open a good mulberry garden waist ditch, ditch, Tiantougou. The trenches should be connected and the trenches should be matched so that the drought can be filled and the rafts can be discharged. Drought and flood protection.
7. Mulberry intercropping: Mulberry garden interplanting between crops is a comprehensive development and utilization of sericulture resources. It is an important measure to improve the comprehensive benefits of mulberry sericulture. Mulberry intercropping generally includes planting and breeding. Planting industry, mulberry garden suitable for interplanting plastic film watermelon, melon, plastic film peanut, a variety of vegetables. Maidi Sangyuan can be grown without mulch in the summer; in the development of the aquaculture industry, mulberry gardens can be fenced with grass or chickens or geese. The chicken eats grass and eats chicken manure. Each mu can be stocked with 30-50 stocks. In the mulberry garden, raising goose, goose eating weeds, geese droppings and fattening fields, raising chickens and raising geese are mutually beneficial. Please vigorously develop.
Eight, sericulture is estimated: According to the above requirements of the management of mulberry garden, when the autumn and next year, the spring period, each period of about 3-4 mu can raise a silkworm; beginning next fall, is basically put into production mulberry, normal mulberry per acre During the period, 1 to 1.5 silkworms can be reared, and a well-managed and high-yield mulberry garden can raise about 2 silkworms per acre.
Nine, sericulture preparation: The main preparation for silkworm or greenhouse, silkworms and cooking utensils. Generally speaking, every one silkworm is raised, about 30 square meters of silkworm area (ie, greenhouse area or silkworm area); 4-6 silkworm cocoons; 150 grasshoppers, etc.
