A method of mulberry overwintering safely

Abstract

The invention relates to a safe fruit mulberry overwintering method. The method includes the following steps of firstly, shaping and trimming tree bodies in the middle ten days and the last ten days in October each year to remove weak branches, lower branches and irregular branches, and regulating the height of the tree bodies to be 2.5 m or lower; secondly, conducting branch bundling in the first ten days in November, bundling and wrapping trunks through straw in the last ten days of November, sealing and wrapping whole fruit mulberries through plastic bags, and finally wrapping a layer of windtight gunny bag or blanket on the wrapped fruit mulberries; thirdly, conducting winter irrigation once during the period from the middle ten days and the last ten days of November and the first ten days of December; fourthly, relieving wrapping and branch bundling in the middle ten days and the last ten days of March in the next year. By means of the method, the survival rate of fruit mulberries reaches up to 98% or higher after the fruit mulberries experience the extremely-low temperature in winter, all fruiting branches are stored, and the fruit mulberry growth and the high-yield harvesting of fruit mulberries in the next year can be normal. The safe fruit mulberry overwintering method has the advantages of being low in cost, convenient to operate and good in effect.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for safely overwintering fruit mulberries. Background technique [0002] Fruit mulberry is listed in the list of more than 80 kinds of plants that are "both food and medicine" determined and announced by the National Health and Family Planning Commission. It is a booming emerging medicine and food homology industry. The whole body of fruit mulberry is full of treasures, mulberry fruit (mulberry), mulberry branches, and mulberry white bark are all precious Chinese medicinal materials, while mulberry leaves and mulberry fruits are nutritious foods. At the same time, mulberry fruits belong to the third generation and have significant health benefits. fruit. Therefore, fruit mulberry has become a priority development industry in most regions of the country including Xinjiang and Northeast my country. The critical problems that production is currently trying to solve. ...

AI Technical Summary

Problems solved by technology

[0003] For areas with low winter temperatures such as Xinjiang and Northeast China, most of the mulberry industrialized varieties are non-local varieties with poor cold resistance. After the extreme low temperature in winter, some varieties cannot survive at all. Even if they survive, most of the branches of the mulberry fruit have been frozen. Death will lead to the failure of the mulberry harvest in the second year, so extreme low temperature is a key issue that seriously restricts the production of fruit mulberry

[0004] At present, fruit mulberry wintering generally adopts methods such as soil burial and the use of antifreeze agents. The soil burial method is labor-intensive, high in cost, and cannot fundamentally solve the problem of fruit mulberry industrial production; The survival rate of the fruit mulberry and the survival rate of the fruiting branch are restricted. In summary, the methods currently used for the prevention and treatment of the low temperature and freezing damage of the fruit mulberry cannot fundamentally solve the problem of a safe overwintering place for the fruit mulberry.
