What impact does sand and dust weather have on spring plowing season? How should losses be reduced?
In our local area, we grow various non-seasonal vegetables, such as cucumbers, tomatoes, eggplants, zucchini, peppers, and various leafy vegetables, such as rapeseed, lettuce, spinach, etc., and Melon, strawberry, etc. Strong winds and dust will affect the emergence and growth of field crops. Due to the effect of wind and sand, the mulch films in the fields are blown open and torn, and some even blow away the seeds, causing moisture loss and seriously affecting crop emergence.
The strong wind and dust in spring will scatter the seeds of crops, thus greatly reducing the probability of crop birth and affecting the sowing of crops. At the same time, wind and dust blow away farmland or farmland, making the land drier and making it difficult for crops to grow. Water extraction does not damage the environment, fixed-point water supply is easy to manage, no leveling is required for a 400-meter height difference, and physical and chemical properties will not be reduced for a hundred years, turning deserts into oasis and fertile farmland.
Ultra-high molecular polyethylene pipelines transport water over long distances without leakage or leakage. They can adapt to complex geological terrains without digging trenches. Water intake at multiple points does not damage the environment. Fixed-point water supply is easy to manage. No leveling is required for a height difference of 400 meters. , the physical and chemical properties have not been reduced for hundreds of years. Nowadays, many plastic greenhouses are used to grow vegetables and fruits. Wind erosion: When strong winds act on loose soil in arid areas, they will remove a layer of topsoil, which is called wind erosion. For example, the average wind erosion depth of the black wind on May 5, 1993 was ten centimeters (up to 50 centimeters), that is, an average of 60 centimeters per acre of land. Up to 70 cubic meters of fertile topsoil was blown away by the wind. (1) Adjust the agricultural planting structure, change the current single planting method in the north, promote grain and grass mixed cropping technology, grain and grass intercropping, and grassland rotation, introduce forage and overwintering crops into the farmland farming system, and increase the surface coverage of farmland in winter and spring. Solar power. Making full use of the space and light energy resources in desert areas and building large-scale contiguous solar farms can not only bring immediate immediate benefits, but also reduce ground evaporation and promote the recovery of surface vegetation.
