Mulberry is a mature fruit of mulberry. The mulberry belongs to deciduous tree, dioecious, and blooms in May. Fruit maturity period from June to July, the fruit is oval or cylindrical, black purple or white. Like to grow in a warm and humid environment, drought tolerant, not waterlogged, and barren. Strong adaptability to soil. So what are the planting skills you need to master to produce high-yield mulberries?

Plastic trim

Usually, the plants need to be cut short at a height of about 25 cm before planting. When the new shoots grow to about 18 cm, they should be topped in time to promote the germination of lateral branches and increase the area of ​​the canopy. In June of the second year after planting, when the mulberries matured, they had to start pruning in summer. Each fruiting branch retains about 3 buds and then cuts shortly to promote the germination of new shoots. In the winter, weed out the weak growth and branches of diseases and insect pests in summer. However, to retain a proper amount of fruiting branches, cut off the unsatisfied parts about 18 cm from the top of the branches.

Water and fertilizer management

The demand for water and fertilizer of mulberries is relatively large, especially in the budding period of spring and summer. If there is a shortage of water in these two periods, water must be replenished in time. Otherwise, the sprouts' growth ability is weak, and it is easy to cause diseases and insect pests, which will have a serious impact on the growth of mulberries. Then apply sufficient base fertilizer in winter every year to control the amount of fertilizer. The main fertilizer is mainly farm fertilizer and reduce the proportion of chemical fertilizer application. After each pruning, appropriate fast-acting nitrogen fertilizer should be applied topically, and foliar fertilizer should be properly sprayed during the flowering period and young fruit period to increase the sugar content of the fruit, promote fruit growth, and improve quality.

Wipe the top

The topping of buds should be carried out according to the age of the trees. As a result, fruit trees over two years old will be budded at the end of March every year. Observe the growth of the fruit tree often, and when the result has about 5 new leaves at the top of the mother branch, begin to top. The specific topping time depends on the planting area and the age of the tree, but generally after Qingming Festival. At this time, topping is helpful to promote the vegetative growth of fruit trees to reproductive growth, promote the light absorption of fruit trees, improve the yield of mulberries, and enhance the quality of mulberries.

Timely harvest

The harvest of mulberries also has certain skills. Under normal circumstances, mulberries usually mature around May each year. Observe the changes of the fruit. When the color of the fruit gradually changes from red to purple, when the surface gloss is transparent, it indicates that the fruit is ripe. When harvesting, pay attention to the harvesting method. Handle it gently to avoid breaking the epidermis, causing damage to the fruit and reducing storage. After harvesting, they should be packed in plastic boxes, etc., and listed in time after harvesting.
