Mulberry technical treatment after spring frost

The need for a process back to life, the recovery time, because there are different levels of mulberry cold, according to the survey, light frost growth period to be delayed 5 to 6 days; freezing heavy, to be delayed 7 to 8 days. Therefore, as long as the appropriate time delay silkworms hatched in spring mulberry leaf yield of almost no yield. Therefore, we believe that should not be cold spring mulberry cutting. (B) hold the appropriate light frost mulberry cutting, to maintain the status quo. Do not need any treatment for frozen section. Severe frost damage in the mulberry trees. Branches can be cut a quarter to one-third, not to cut deals with the general (ie, cut one half of article sorting to two-thirds), due to severe frost even if the primary buds of mulberry frozen section,[link widoczny dla zalogowanych], and vice germination and growth of mulberry leaf buds still; but after the cut-off bar. The germination of buds could also cut off, will cause relatively large spring leaf production. (C) deferred income ants according to a survey in the spring silkworm mulberry age of five, the general growth in the amount of mulberry leaves daily at 2.5 to 3%, as every high-temperature, and then strengthen the water and fertilizer management. 3 or more daily basis by mulberry, mulberry, if subjected to light frost. Cut around the 1O, can delay the closing ants 3 to 4 days; if cold serious about 2o% cut. Ant income may be deferred for 6 to 7 days. Be extended as long as hatched, and its species of silkworms made the amount of the basic maintenance of the original plan can be the same (d) strengthen the management of mulberry. Mulberry was after the spring frost. Should immediately do a good job as management. 1. Frost immediately after the draw hoe Mulberry to increase temperature, to shorten the recovery of mulberry growing season 2. Cut into strips to be immediately cut bar. ~ Determined not to bungle the recovery of the growth of mulberry. 3. Cold in Mulberry, immediately available fertilizer in the furrow opened by the foot leaves 2 to 3 after the foliar fertilizer hoop to /} f one who margin of Ding Pakistan, and,[link widoczny dla zalogowanych], j spoonbills B] 993 No. 4 3l Jiangsu sericulture sericulture specific compound in the promotion of our experience in the fall of Zhao Xichang Zou sound (no curium County town of hard-put more services company) since we started in 1990 in promoting the use of mulberry sericulture by the College of Suzhou and Wuxi County Recovering Fertilizer plant to develop sericulture specific compound, to 1992, the county has 23 towns and three in the field and the original silkworm silkworm district promotion, application of fertilizer in the Mulberry area of 8,000 acres or more. Mulberry area of the county 60 or more. Mulberry silkworm area specific compound has been widely welcomed by the masses. We Xin, Shuofang two set points in rural compared specifically investigated. The single application of chemical fertilizer as a control,[link widoczny dla zalogowanych], a full year Mushi pure nitrogen as the standard 25 kg, respectively,[link widoczny dla zalogowanych], in spring, summer and winter was applied, based compound area, fertilizer + manure areas, an organic chemical nitrogen fertilizer Area three treatments. By 1990, Liu Xuequan (Wuxi Lei Internet service companies and more) S1991 two-year comparative study, the results showed that the compound leaf area per plant produced higher than the control area were 12 and 27 years, fertilizer + organic fertilizer area higher than 24 and 32, respectively, while the area of chemical fertilizer + organic fertilizer were only increased by 5 and l2. Shall have the same situation a long tendency (Table 1). Mulberry application of fertilizer per plant than with N fertilizer can increase Mulberry Mulberry 0'2 ~ 0.4 kg, total 1200 acres planted, yield per mu of mulberry leaves 240 ~ 480 kg. If the combined application of organic fertilizer. Stimulation effect is more obvious: the same time, mulberry, after application of fertilizer can increase soil phosphorus and potassium content of mulberry. Table 1 leaf yield of different fertilizer application compared the project base annual leaf consumption (Pi kg / plant) means the average Qiang Indigo length (cm / bar) index area 19901.81l12135l09199l2ool21231l5 compound fertilizer + organic fertilizer ammonia fertilizer chemical District l99019912414lll41991209132129l21199o1_69105 + organic fertilizer District l99l1-7ll2199o1.611D0124 single application of chemical fertilizer District 199ll581i) ol07 mulberry leaves to promote accelerated growth and late maturity. (E) cutting technology to improve the summer. Shoots in the upper section Sang Sang Chan seriously cream. After the buds were frozen to death. Growth advantage to break the top of mulberry, prompting some of the lower branches generate growth and bud germination of dormant buds of mulberry summer to be improved when cutting bar cutting technology, the When the election is to stay in the mining branch leaf base 2 to 3 growth buds that do not use (the lower part of each bud of mulberry leaves can be used), the rest of the growth of shoots and buds all cores collected only to feed silkworms and mulberry leaves at any time taken to light strip cut,[link widoczny dla zalogowanych], so that the growth of buds left to continue growing. This allows the spring summer and left after cutting buds will continue to grow, so that uninterrupted growth period of mulberry leaves, summer leaves yield about l5; other hand, the mulberry tree after frost delays caused by deferred income ants cutting the summer time, but also thus be filled. The following year when the summer cutting. Then adjust the tree will be cut back to leave a part of the cutting part of a normal summer. So. This method can also rejuvenation mulberry. Mulberry conducive to increase the following year.
