What is the impact of dusty weather in spring ploughing season? How to reduce losses?

In our local area, there are all kinds of out-of-season vegetables, such as cucumber, tomato, eggplant, zucchini, pepper and various leafy vegetables, such as rape, lettuce, spinach and so on, as well as melons and strawberries. Strong wind and dust will affect the emergence and growth of crops in the field. Due to the action of wind and sand, the plastic film in the field was blown open and torn, and some even blew the seeds away, causing soil moisture loss and seriously affecting crop emergence.

The strong wind and dust in spring will blow away the seeds of crops, thus greatly reducing the fertility probability of crops and affecting the sowing of crops. At the same time, dust blows away farmland or farmland, making the land drier and crops difficult to grow. Water intake does not damage the environment, fixed-point water supply is easy to manage, the height difference of 400 meters does not need to be flat, and the physical and chemical properties do not decrease for a hundred years, making the desert an oasis fertile field.

Ultra-high molecular polyethylene pipeline has no leakage in long-distance water supply, adapts to complex geological terrain, does not need to dig trenches, does not damage the environment by taking water at multiple points, and is convenient for fixed-point water supply management. The height difference of 400 meters does not need to be flat, and the physical and chemical properties will not be reduced for a hundred years. Nowadays, many vegetables and fruits are grown in plastic greenhouses.

Wind erosion: when strong wind acts on loose soil in arid areas, it will scrape off a layer of topsoil, which is called wind erosion. For example, on May 5, 1993,/kloc-0, the average wind erosion depth of black wind was 10 cm (at most 50 cm), that is, an average of 60 to 70 cubic meters of fertile topsoil per mu was blown away by the wind. (1) Adjust the agricultural planting structure, change the current single planting mode in the north, popularize the techniques of grain-grass mixed cropping, grain-grass intercropping and grass-field rotation, introduce pasture and overwintering crops into the farmland cultivation system, and increase the surface coverage of farmland in winter and spring. Solar power generation. Making full use of space and light energy resources in desert areas to build large-scale contiguous solar power stations can not only bring immediate visual benefits, but also reduce ground evaporation and promote the restoration of surface vegetation.
