通过对高产棉田和普通棉田的生长状况、植物和土壤水分平衡与热量平衡的研究 ,提出在沙壤地的普通棉田 ,采用“轻灌勤灌”的灌溉方法 ,是改善棉田水热平衡 ,获得高产的有效技术措施 Based on the research on the growth status, plant and soil water balance and heat balance in high-yield cotton fields and ordinary cotton fields, it is proposed that the irrigation method of “light irrigation and ground irrigation” in ordinary cotton fields of sandy soil is to improve the water-heat balance in cotton field and obtain high yield Effective technical measures
