Mulberry Garden Management Needs To Be Strengthened In Guangxi's Main Silkworm Producing Areas

1-3 December 2010, state Sericulture Zhu Fangrong, a research expert in the industrial technology system, led a team of senior agronomist Lin Qiang to the national sericultural industry technology system Hechi comprehensive experimental station, Guangxi innovation team Yizhou comprehensive test station and Liucheng County for sericulture technology training and guidance for winter mulberry management.

In the training class, Zhu Fangrong researcher analyzed the current situation of sericulture development in our region and taught the cultivation techniques of mulberry high yield, high quality and high efficiency. During the training and investigation, the leaders and technicians of the city and County Agricultural Bureau, experimental station, sericulture station and sericulture office were conducting research and communication on demonstration and promotion of disease prevention and High-yielding Winter cutting technology.

Zhu Fangrong researcher pointed out that in recent years, some sericultural areas Mulberry garden Winter cutting is not standardized. First, the winter cutting time is generally too late, until the mulberry trees have sprouted or the young leaves have been cut down. At this time, mulberry trees have consumed a lot of nutrition. Two, root cutting methods are used to cut off all the growth branches in the second half of the year, that is to say, the nutrients and anti disease substances accumulated from the branches are cleared up, resulting in slow growth of mulberry trees in spring, small leaves, and outbreak of mulberry mosaic disease, which seriously affects the yield and quality of spring leaves.

In response to these problems, he urged all localities to publicize vigorously. Demonstration and extension The mulberry garden must be carried out 10 days before and after the winter solstice (i.e. 17 to 27 December), not to carry out the winter cutting on the branches and avoid the loss of tree nutrition; two is to change the old habit of cutting roots (cutting to roots or flat cuts), and adopting the way of keeping long branches in winter, that is to cut the branches that are half a year old to grow 30 to 50 centimeters, and to cut down the weak branches of the disease branches. In this way, mulberry trees sprout early, germinate and grow vigorously, and the mulberry trees are fast sealed, and the leaves are thick and thick. They can effectively control the occurrence of mulberry mosaic disease, enhance the ability of mulberry trees to resist other diseases, and increase the yield and quality of mulberry spring leaves in a large scale. To standardize scientific winter cutting technology, first, timely winter cutting.
