摘要:
分析总结了开发农田蒸发水的可行性、可能性，调查了降雨量、蒸发水对旱区作物产量的影响及试验研究，提出了"留茬免耕秸秆全程覆盖"耕作新技术.在我们试验条件下，"留茬免耕秸秆全程覆盖"技术较传统耕作技术，小麦增产56.4%，玉米增产87%，夏闲期土壤含水量增加4.4%.多年试验、示范结果表明："留茬免耕秸秆全程覆盖"是减少农田蒸发水、解决旱地农田干旱、增产增收、保护生态、培肥地力、投资少、易操作的一项先进实用技术.
Abstract:
The authors analyse and summarize fecesiblcy and probably of exploitation farmland evaporation water;At the same time,the effects of precipitation and evaporation to grain yield were investigated and field experiments ware conducted,with"left stubble non-tillage straw mulching for whole growing process"cultivated new technique.On our experiment condition,with the technique raising wheat yield 56.4%,raising maine yield 87%,soils content of water increasing 4.4% in 0～200 mm in summer fallows than tradition tillage technique.The numerous experiment and demonstrate results shown:" left stubble non-tillage straw mulching for whole growing process" is the advanced applied technique of reducing farmland evaporation,improving dryland,increasing yiely and income,protecting ecology,fertility raising,little input,operating easy.
