The output of mulberry will be different due to varieties, planting techniques and other factors. Under normal circumstances, the yield per mu of mulberry trees is about 4000 to 5000 Jin.

Cultivation methods of high-yield mulberry;

1, land consolidation?

Mulberries should be planted on flat and pollution-free land and close to water sources. First of all, we should dig a tree pit with a depth of 50 cm and a width of 50 cm, apply compound fertilizer on the surface soil, then fill the soil and submerge the compound fertilizer, and apply 40 kg of compound fertilizer per mu to improve the survival rate. Mulberry of general varieties has upright branches and compact trees. At the time of initial planting, there should be enough space between saplings. The planting density is generally 3 × 2m, and about 100- 120 plants can be planted per mu.

2. Water and fertilizer management?

The water demand period of fruit mulberry is mainly in spring and summer, and the water demand of mulberry is not large, and the roots are deeply buried in the soil, which provides sufficient water for the roots, but attention should be paid to watering to prevent drought. Generally, many farmers decide the amount of water according to the actual situation of the land. Fertilization should be carried out according to the land every year, usually in winter and summer, and the amount of fertilization depends on the land situation. Generally, 25 kg of Woye compound fertilizer or 20 kg of urea are applied per mu; Fertilization is very beneficial, which can not only increase the sugar content of fruit, but also promote early maturity and ensure the yield of mulberry fruit to be improved.

3, timely harvesting

Generally speaking, mulberries mature around Tomb-Sweeping Day every year. When the mulberry fruit just turns from red to black, the fruit is crystal clear, which is a sign of mulberry maturity. When the fruit is ripe, it should be harvested every morning. Mulberry is fragile. When picking, gently touch the root to pick. First, put it in a small plastic box. Don't break the skin of the fruit, otherwise it will be stale and difficult to preserve.

4, pest control

There are many ways to prevent and control mulberry diseases and insect pests, and the methods that can be taken are as follows:

(1) Every winter, the pruned litter should be burned. After burning, the soil should be deeply ploughed and fertilized.

(2) The initial flowering stage, the full flowering stage and the final flowering stage should be observed in the field, and 75% chlorothalonil 800 times solution or 70% thiophanate-methyl 1000 times solution should be sprayed once each, with an interval of 7 days. ?

(3) During the high temperature and rainy period in July, August and September every year, it is necessary to observe in the field once every 10- 15 days, and the spraying frequency is flexibly controlled according to the actual situation in the base area, so it is not necessary to copy it completely.

5, plastic pruning

From May to June every year, almost all mulberries are ripe for picking. At this time, mulberry trees can be trimmed. This measure can better ensure that the seedlings have enough growth space and improve the light transmission and ventilation of the trees. At the same time, pruning branches and leaves can make the leaves evenly distributed, improve photosynthesis and reduce the source of diseases and pests. You'd better choose an earlier pruning time. It is best to pay attention to the length of all seedlings as soon as possible after mulberry is ripe and picked, so as to promote the germination of its new branches.
