地膜小麦集水灌溉技术研究

The Irrigation Technique Pooling Water with Plastic Film of Wheat

将旱地农田小沟垄集水和覆膜穴播增温保墒节水效果有机地结合在一起,充分接纳雨水,集水保墒,有效地提高了土壤耕层含水量和地表温度,增产增收效果显著。地膜小麦集水补灌,不同时期、不同补灌量处理间产量存在显著差异。从补灌时期看,以拔节期补灌产量最高,其次为扬花期,再次为冬前。从补灌量看,在同一补灌时期,补灌量高者产量高,每次补灌量应不低于150 m3/hm2。

On the base of spreading and using the technique of plastic film covered the fields, the scientific researchers have done a lot of research to it the that the irrigating technique pooling water with plastic film is used at wheat, gratifying results have been achieved, several practicing techniques that can be used at dry,semidry or slight dry farmlands have been created. The results showed that wheat yield was significantly different when irrigated in varying periods or with different quantities. Judged by＇irrigation period, the sequence of wheat yield was jointing stage〉flowering〉before winter. Judged by irrigation quantity, the higher the irrigation quantity in the same period, the higher the yield of wheat. The quantity is better higher than 150 m^2/hme for each irrigation.
