Problems solved by technology

Since potato planting must be plowed in autumn, and there are more than 40 windy days in winter and spring, the surface soil is severely eroded by wind, which is also a potential problem that the overall destruction speed of desertification in this region is still faster than the control speed

Embodiment Construction

[0010] Such as figure 1 As shown, this research plan adopts the method of inserting cereal crops that are easy to stubble at intervals in the potato planting fields that must be plowed over a large area. In winter and spring wind erosion seasons, the vertical poles of the cereal crops that are easy to stubble are used to block and improve intercropping. The wind speed threshold for turning over bare land to realize the reduction of wind erosion of farmland soil. The implementation steps are as follows:

[0011] ①Planting method: In spring, in the field where potatoes were planted on a large scale in previous years, the potatoes were planted with a certain width and a certain width was vacated. Form a strip intercropping layout of potatoes and cereal crops that are easy to stubble. Two rows of quinoa were transplanted in the band-shaped stubble intercropping field with a width exceeding 8.4m.

[0012] ② Determining the bandwidth: It is best to have the same width as the stub...

Abstract

The invention discloses a method of building a field biological fence, which mainly includes: sequentially planting ceratoides latens, cereal crops and potato at intervals in a plot from west to east, namely transplanting seedlings of the ceratoides latens from west to east, planting the cereal crops to the east and planting the potato to the east; repeating sequential planting of the three types of crops from west to east. The transplanted ceratoides latens is clipped once three years before reviving in spring, stalks of the cereal crops are maintained 15cm-20cm in height during harvest in autumn, ploughing and leveling are performed after the potato is harvested, and accordingly the field biological fence is formed. The method is simple in operation, has the double functions of increasing yield and income and protecting field ecological environment, and is practically suitable for northern dry farming areas to develop characteristic commercial crops and expand forage grass production.

Description

technical field [0001] The invention relates to a construction method of a biological fence net, in particular to a construction method of a biological fence net for windbreak and soil fixation in farmland. Background technique [0002] In the interlaced area of ​​agriculture and animal husbandry in northern my country, the soil wind erosion of dry farmland is serious in winter and spring, which is superimposed with the natural characteristics of strong winds, snowfall and little rainfall in the same period, resulting in a large area of ​​farmland with bare surface and loose topsoil. This area has become the northwest path An important reinforcement zone for dust sources. In recent years, potatoes have been widely planted in this area as the main economic crop. Since potato planting must be plowed in autumn, and there are more than 40 windy days in winter and spring, the surface soil is severely eroded by wind. This is also a potential problem that the overall speed of deser...
