旱管稻不同覆盖物比较试验表明 ,采用地膜覆盖 ,土壤保墒性能强 ,水稻植株生长健壮 ,易达到早发、早够苗、成足穗的目的 ,有利于旱管稻产量的提高。覆盖秸秆保墒效果较差 ,且影响分蘖期地温上升 ,影响水稻产量。覆盖经腐熟过的秸秆 ,在水稻生育期间可以腐烂利用 ,达到增产的目的。
The comparative experiments of different covering of dry-pipe rice showed that the use of mulching, strong soil moisture retention, robust growth of rice plants, easy to achieve early hair, early enough seedlings, into the ear, is conducive to improving the yield of dry pipe rice. Covering straw moisture conservation effect is poor, and affect the tillering temperature rise, affecting rice yield. Cover the matured straw, rice can be decomposed during growth, to achieve the purpose of increasing production.
