旱作水稻稻茬小麦增产栽培技术研究

STUDY ON CULTIVATION TECHNIQUES OF INCREASING PRODUCTION IN WHEAT GROWN AFTER DRY RICE HARVESTS

水稻稻茬小麦因水稻收获晚、适耕期短、整地困难、播种质量差等因素的影响，很难适期播种，加之水稻稻茬土壤板化，理化性状差，导致稻茬小麦的单产长期低而不稳，在２００ｋｇ上下徘徊。为改变这一现状，我们提出了以旱作水稻替代水稻，并进行试验研究。结果表明，旱作水稻比水稻早熟１０天，并能调整土壤理化性状，旱作水稻稻茬小麦比水稻稻茬小麦增产１００ｋｇ。

Wheat grown after the rice harvest is very difficult to sow in time, because rice is harvested too late. In addition, the soil after rice harvests is hardened and impervious, not good in functions of physics and chemistry, so the production of wheat grown after rice harvests is low and unstable. To change the situation, we advance a test of replacement of rice by dry rice. The result displays that wheat grown after dry rice harvest has increased by 100 kg, because dry rice ripens 10 day earlier than wheat grown after rice and the function of soil can be regulated in physics and chemistry features.
