Mulberry Winter Pipe Grabs Five Points
The management of winter mulberry fields is an important part of the management of mulberry fields throughout the year. It has the features of avoiding busyness and leisurely use and being economical and effective. It has the effect of reducing pests and diseases in mulberry fields, increasing tree vigor, and increasing the yield and quality of mulberry leaves in the following year. .
After the whole plant is exterminated, after the deciduous mulberry leaves fall to the sap flow in the spring of the next year, use small saws or pruning shears to cut off the dry piles, branches and branches of the mulberry tree and the weak pendulous branches, so as to maintain the tree shape and enhance the tree vigor. Improve the light and ventilation conditions inside the mulberry garden and the crown, so that the nutrient concentrate supply the growth of the shoots, and promote the increase of the germination rate and leaf quality in the following year. For the piles, pests and branches that have been cut off, the mulberry field should be promptly brought out and burned. For tree trunk holes and cracks, lime and clay are mixed and mixed into a paste plug to eliminate pests that inhabit winters and prevent the intrusion of rain and snow into the hollow of the trunk.
The replanting of the excavated strains of mulberry trees suffering from mulberry tree atrophy disease, purple feather disease, and root knot nematode disease, and mulberry trees that are seriously endangered by Tianchi is not only low in yield but also poor in leaf quality, and it also spreads and spreads the occurrence of pests. Dig out in time. After the excavation, the diseased soil inside the hole should be sterilized with fungicides and nematicides, and then the new mulberry should be replanted to ensure that there are enough trees in the mulberry field. The replanting of the new mulberry should be carried out before the soil is frozen. The mulberry trees used for replanting should use thick, high-quality grafted seedlings, and it is best to use 2 to 3 year-old saplings for transplanting.
Fertilizing Winter Irrigation Before the soil is frozen in mulberry gardens, sufficient manure, cooked silkworm sand, human excrement, and other organic fertilizers must be applied. This has a very important role in increasing the output and quality of mulberry farms in the following year. The fertilizing time is applied after the completion of the mulberry garden clearing garden and is applied from late November to early December; the fertilization method is applied to the mulberry trees for digging or spreading; the amount of fertilizer applied is 2500 kg of organic fertilizer per acre of mulberry garden. In combination with winter plowing, the manure is turned into the soil. Winter irrigation time, before the winter plowing after applying the winter fertilizer, is beneficial to the mulberry winter, on the other hand can also make the soil through the frost and loose.
Winter ploughing and winter ploughing can loosen the soil compaction caused by mulberry harvesting, handling, and rainfall, and improve the permeability of soil in the past year, making the nutrients in the lower layer of the soil less absorbable and becoming nutrients that can be absorbed, and can promote soil In the proliferation of beneficial microorganisms, the soil can be loosened by freezing and thawing to further improve the water, fertilizer, gas, and heat conditions in the soil. At the same time, it also has a good killing effect on pests that overwinter in the soil. Winter ploughing time is generally performed before soil freezing; young mulberry trees with a depth of winter ploughing of less than three years can be appropriately lightened; mature mulberry fields can be kept at a height of about 20 cm; It is advisable not to break rough roots.
Prevention and control of pests 1 Late autumn spraying After the end of autumn feeding, it is necessary to uniformly spray 1 high-efficiency pesticide on the mulberry garden, such as spraying 2000 times liquid of the enemy, effectively killing pests such as mulberry caterpillars, wild silkworms and mulberry horses; 2 scraping In addition to egg masses and pathogens, scrape the mulberry and wild egg masses on the trunk with bamboo pieces, and brush the trunk with lime slurry or lime sulfur; 3 Prevent scale insects Mulberry scale insects mainly live on mulberry branches and stems, and winter can be used for grass. Such obliteration, early spring (late February to early March), after its nymphs hatch, in addition to obliterate, can be used to add 2% detergent powder by adding 50% of the marathon emulsion 1000 times; 4 control Mulberry parasites in the trunk The mulberry larvae can be injected with kerosene, etc. to kill it; 5 early spring spray lime sulfur mixture also use Baume 5 degrees lime sulfur spray trunk, shoots, to prevent pests and diseases.
