沭阳县地处黄淮海平原南部,全年的热量资源能满足原来种植成熟期较短的中籼或中粳和偏春性小麦的需要。现改种生育期较长的籼型杂交稻和半冬性小麦后,热量资源不足,季节和劳力紧张。杂交稻若按常规方式育秧移栽于麦茬,往往成熟期迟,结实率低,产量不高,并且腾茬晚,还影响小麦生产。为此,我们进行了多种方式培育多蘖大苗的试验,以探索不同的方式对秧苗素质及产量的影响,为杂交稻培育壮秧提供依据。 Shuyang County is located in the southern part of the Huang-Huai-Hai Plain. Its annual heat resources can meet the needs of the original middle-aged or middle-aged wheat with short mature maturity. Now planted a longer growing period of indica hybrid rice and semi-winter wheat, lack of heat resources, seasonal and labor-intensive. Hybrid rice if conventional methods of transplanting seedlings planted in wheat stubble, often late maturity, seed setting rate is low, yield is not high, and Tengcu late, but also affect the wheat production. To this end, we conducted a variety of ways to cultivate more tiller seedlings trials to explore different ways on the quality and yield of seedlings, providing strong evidence for hybrid rice cultivation strong seedlings.
