在旱作区，利用小麦收割后的根茬、杆草、麦糠等物，适时的覆盖在花生行间，可起到减轻土壤板结，改善土壤结构，增加有机质，培肥地力，提高旱地蓄水保墒的能力。生产实践表明，麦套花生在同等条件和一定范围内随着根茬覆盖量的增加，花生营养体生长量有增长的趋势，单株结果数和饱果率提高，平茬麦套覆盖增产４．７４％～１４．１％，高留茬覆盖增产７．９％～２１．７％。 In the rainfed area, the use of wheat stubble after harvest, bar grass, wheat bran and other timely coverage of peanut in between, can play to reduce soil compaction, improve soil structure, increase soil fertility, improve soil fertility and improve dry storage Water conservation capacity. The production practice shows that the growth of peanut vegetative body increases with the increase of stubble coverage under the same conditions and within a certain range. The number of peanut vegetative growth and fruit ripening rate increase, .74% ~ 14.1%, high stubble coverage yield 7.9% ~ 21.7%.
