研究发现：旱地产量为最干旱时段的土壤水分（旱点）所制约，进而认识到，旱地农业生产力似存在二重“箍桶效应”现象。二重“箍桶效应”揭示出旱地还有较大的水分潜力；据此提出了技术对策：对无客水补充条件的耕地，立足于当地年降雨总量，将灌区又作为水源地，汇集降雨高峰期部分雨水并妥善蓄存，灌溉于作物最感干渴的时段，获取相对高产与稳产。由于灌区与水源地重合，故将此对策命名为耕地集雨就地灌溉。据估算，此项技术可能是北方旱地农业粮食增产的突破口和解决水资源短缺的战略措施。
The study found that the dry land production was controlled by the soil water content (drought point) in the driest period, and then realized that there was a double “hoop and barrel effect” phenomenon in dryland agricultural productivity. The double “hoop barrel effect” reveals that there is still greater potential for water in dry land. Based on this, a technical countermeasure is proposed: for cultivated land with no passenger water supplementing conditions, based on the total amount of annual rainfall in the area, the irrigated area is also used as a water source During the peak rains, part of the rainwater is stored properly and irrigated during the thirst of the crop, giving relatively high yields and stable yields. As the irrigated area coincides with the water source, it is named as in-situ irrigated farmland. It is estimated that this technology may be a breakthrough in the agricultural production of dry land in northern China and a strategic measure to solve the water shortage.
