摘要
针对固定道保护性耕作沟灌情况下,水分侧渗速度慢等问题,研制了两种形式的垄作割刀。通过田间试验分析了两种割刀对土壤含水量、地温及春小麦植株性状的影响。结果表明:经过割刀处理的垄能够有效地促进侧渗,较好地改善春小麦植株性状,提高其产量。
As to the slow side infiltration Problem of PRB （Permanent Raised Beds） system＇s furrow irrigation, two kinds of sweeps have been designated. Elementary Field experiment was contrived to analyze the effects of sweep treatments in the soil moisture content of different depths, the field temperature, and the characters of spring wheat. Results reveal that the operation of sweeps can promote side infiltration in beds effectively, improve the characters of spring wheat plants well and increase its yield.
