After the mulberry trees were harvested and the summer mulberry trees were harvested, all the soil between the rows was exposed, which had no inhibitory effect on the growth of weeds and could easily lead to the formation of grassland. Therefore, mulberry trees must be timely weeded after summer harvest to control the growth and spread of weeds. After the waterlogging of the mulberry tree, the roots of the mulberry tree in the underground area also shrink and fall off at the same time. As the ground sprouts long leaves and grows new roots, in order to adapt to the rapid growth of the aboveground parts, the new mulberry water absorption fertilizer The ability is greatly enhanced. However, in the case of continuous rainy weather, the drainage of the mulberry canals is not easy, resulting in water accumulation in the mulberry fields, severely affecting Sanggen's respiration, weakening the ability to absorb water and fertilizer, and even suffocating death. Therefore, the mulberry trees must be cleaned up after the summer harvest so that they can communicate with the canal and canal, and the drainage can be smooth and dry. After the three pests prevent the damage of mulberry trees, they are also the season of various pests, seriously destroying the quality of mulberry leaves, reducing the yield of mulberry leaves, and even endangering the safety of silkworms. Therefore, the mulberry tree must be observed regularly after the summer mulberry, so that timely control. It prevents and treats leaf pests such as mulberry caterpillars and wild silkworms and controls other pests such as mulberry horses. Four Prevention of Mulberry Mulberry After the summer harvest, the growth of the mulberry tree is greatly affected. To restore the tree vigor early, promote early germination, and increase the number of long leaves, a large amount of fertilizer must be added to provide for the growth of the mulberry tree. Generally, the first fertilization is applied at the beginning of July. About 20 kg of urea and 40 kg of adult manure is applied per acre; the second time can be applied at the end of July to the beginning of August, with 15 kg of urea per acre. Fertilizer should be deepened to improve fertilizer efficiency. . NINGBO VOICE BIOCHEMIC CO. LTD , https://www.medicine-voice.com
