摘要
草肥(绿肥或秸秆)覆盖耕作具有明显的保水增肥效应,可大幅度提高旱地小麦产量。每亩用2000kg绿肥覆盖休闲期麦田,可增加蓄水50mm左右,同时增加土壤有机质和养分含量,可增收小麦150kg以上。试验认为,合理的草肥覆盖耕作方式是小麦和绿肥牧草实行条带间隔种植,以草养麦,麦草轮作,可大大提高经济效益和生态效益。
Green manure(green manure crops or crop stalks)mulching cultivativation is of anapparent effect to conserve soil moisture,enrich soil fertility and increase wheat yield inrainfed land by a wide margin. 2000 kg of green manure used to mulch one mu to beplanted with wheat during summer fallow can increase Water storage of 50 mm or so,and also,soil organic matter and nutrients,thus,resulting in an increase in wheat yield ofover 150 kg. The experiments show that rational green manure crop mulching cultivationis the way to practise strip rotation of wheat with green manure and forage crops so asto achiveve the rotation of green manure crops to feed wheat with a big increase in eco-nomic results and ecological benefits.
