Spring Harvest Mulberry Garden
In order to maintain a good tree and mulberry tree rejuvenation, the young and senescent mulberry trees of the year or two should undergo spring cutting. That is, the mulberry should be cut before the spring mulberry sprouts, so that the mulberry sprouts can be germinated from the cut. The spring-cut silkworm leaves of the mulberry field have only the sparse buds and the roots of the mulberry leaves, and the amount of the leaves only accounts for about 20% of the summer mulberry trees. However, during the period from the end of spring silkworms to summer silkworms, the labor force in rural areas was more vacant. Both temperature and rainwater were suitable for the long development of mulberry trees. Spring mulberry groves had lush foliage and many branches on the branches. These mulberry leaves were raised. An early summer silkworm can significantly improve the economic benefits of mulberry fields. Investigations, spring harvesting of mulberry gardens until the end of June, normal management of mulberry cultivation, average length of 1.3 meters, with 32-34 leaves, large and thick leaves, green leaves, mulberry branches have grown more than 50 days, If the summer silkworms are reared at regular times, the leaves of the branches have become ageing, and even the yellowing has fallen off, resulting in reduced leaf quality or waste of mulberry leaves; therefore, the spring cutting mulberry gardens can be reared in the early summer silkworm 10-15 days in advance. According to the comparative test, the early-early summer silkworm was earlier than the early-season silkworm, and the yield per mu per mu increased by 14.2% and 15.3%, respectively.
In the spring-cut mulberry field, the following work should be done on the summer silkworm:
1. After the silkworm has been strictly disinfected, the silkworm has to seize the time strictly to complete the strict disinfection of the silkworm silkworm enclosure and its surrounding environment to prevent the pathogen from infecting the early summer silkworm, so as to ensure the early summer silkworm safety.
2. Feeding summer and autumn silkworm varieties The temperature during the early summer silkworm rearing period is more suitable for the growth and development of silkworm larvae, and it is necessary to seize the high yield of silkworm pupa and it is advisable to raise summer and autumn cultivars with strong resistance.
3, to strengthen the spring harvesting mulberry tube early summer silkworm rearing, timely mulberry weeding in the spring mulching, pest control, re-apply a fertilizer to promote the mulberry vigorous growth, improve the quality of autumn leaves, in order to facilitate the cultivation of autumn silkworm.
