First, build a garden standard
First, set a good planting ditch, ditch depth 50 cm, width 60 cm, the bottom of the ditch is covered with a layer of straw about 20 cm thick, cover about 10 cm of topsoil, then apply chicken manure, compound fertilizer on the topsoil, and then backfill. A total of 1500 kg of straw, 2,000 kg of chicken manure, 150 kg of compound fertilizer (or 3,000 kg of fertilized farmyard fertilizer and 50 kg of compound fertilizer) were applied per acre. The planting density is generally 1m 2m spacing, 333 mu per plant, 0.8m 1.5m in mountains, hills, and mudflats, and 555 per mu. When planting, the seedlings will be placed in the filling planting trenches, and the roots will be straightened out to extend around, and then the soil will be pressed firmly and watered according to soil moisture.
Second, pruning
After planting, the seedlings are cut short at 20-25 cm from the ground. After germination, 5-6 shoots can be sprouted per plant. When the shoots grow to 15-20 cm, they are picked up to promote lateral branching and increase the crown. (If there are too few toppings in a single batch, it may be repeated 2 to 3 times to ensure that 15 to 18 mother branches are obtained in the year.) At the end of May or early June of the second year, when the mulberry is ripe and harvested, summer trimming is combined with plastic surgery. All the resulting mother shoots are left with 2 to 3 buds short cuts, which promotes their sprouting new shoots as the result of the next year. The short time should be sooner rather than later to ensure that the new shoots grow in sufficient time and accumulate nutrients for flower bud differentiation. Every year after the mulberry harvest, a short cut, gradually forming a low-dry tree. In the winter pruning, the weak branchlets and rotifer branchlets that germinate in summer are all cut off from the base, and the resulting mother branch is appropriately short-cut, generally cutting the tip of the shoot tip to 20-25 centimeters.
Third, wipe the leaves
The germination time is generally in the middle or late March, eradicating adventitious buds on the stem, resulting in weak buds at the base of the mother branch; the leaves are picked 5 to 7 days before ripening, ie about 25 days after flowering. Two to three leaves of the base are used to enhance sunlight exposure and utilize nutrient accumulation to improve fruit quality.
IV. Water and fertilizer management
The fruit mulberry water requirement period is mainly the spring sprouting period and the summer budding period. If there is a drought in these two periods, the condition should be replenished in time. Fertilize in the middle of the planting line every winter. The amount of fertilization and fertilization method are the same as the “Construction Garden Standard†(or reduce the fertilizer by applying farmyard manure); after summer shear, 50 kg of carbon ammonia or 20 kg of urea are applied in Mu; the flowering period and young fruit At the same time, a 0.3% potassium dihydrogen phosphate solution was sprayed on the leaves (both sides of the leaves were sprayed, and the absorption rate of the dicotyledonous leaves was 5 times higher than the positive leaf surface) to increase the sugar content of fruit and promote early maturation. Mulberry fruit color, stable production and increase production.
V. timely recovery
General mulberry matures in early May. When the mulberry has just turned black from red, and the crystal is bright, it indicates that the mulberry has matured. It should be timely harvested in the early morning. Be careful not to break the skin, first use a small plastic box, Reloaded into cartons, generally weighing 10 to 15 kilograms per carton, can be shipped to the market for sale.
VI. Pest Control
The pests that damage fruit mulberry mainly include mulberry caterpillar, mulberry mulberry, diamond leafhopper, and mulberry celestilla. The diseases mainly include brown spot, anthracnose, powdery mildew, and sclerotinia. Comprehensive prevention and control methods should be adopted:
(a) Each year littered litters are burned in winter and combined with fertilization.
(2) Disinfect the shoots and the whole garden with 3 Baume degrees of lime sulfur before germination.
(C) Spray 75% chlorothalonil 800 times (at intervals of 7 to 8 days) at the initial flowering stage and full flowering stage, respectively.
(4) If the mulberry sclerotinia is a nuclear disease, the diseased fruit should be removed and taken out of the orchard for burning and burial.
(5) Applying white to the sites of semi-lignification and lignification of branches to prevent Sangtianniu from late June to mid-July; if it is found that Sangtianni is harmful to stems, larvae can be used for injection of medicines or drugs. Into, found that adults can be captured manually.
(6) During the high-temperature and rainy periods of July, August and September, every 10 to 15 days, spray 40% omethoate 1200 times with 75% thiophanate-methyl 1200 times, or enemy kill 2000 times plus 75 % chlorothalonil 800 times liquid, the two combinations are best used interchangeably to control mulberry caterpillars, brown spot and other pests and diseases.
