Abstract:

The main crops (corn, sorghum, millet, soybean and peanut) in Jalaid Banner of Xing’an League of Inner Mongolia are cultivated by ridge film furrow cultivation with micro water collecting in field, so that the natural rainfall could be enriched into the ditch, which could improve the soil water environment of crop root zone and improve the utilization rate of farmland precipitation resources. Ridge film has the dual functions of runoff producing and soil water evaporation control. It can not only increase the soil water storage, but also reduce the evaporation between crops, and effectively inhibit the non-target output of farmland water. By using the cultivation method of ridge film furrow planting with field micro water collecting in 2018 and 2019, the results showed that the yield of spring maize, sorghum, soybean, millet and peanut increased by 19.36%, 38.24%, 30.44%, 19.33% and 3.46%, respectively. The cultivation method of ridge film furrow planting with field micro water collecting has certain yield increase effect on corn, sorghum, soybean and millet, and could save labor and time, and the furrows dug once could be used for many years. In addition, the technology could reduce surface soil wind erosion and soil erosion, increase ground temperature and reduce weeds in field.

Key words: main crops, corn, sorghum, mille, soybean, peanut, ridge film furrow planting, micro water collecting, yield increase effect, analysis.
