灾害性天气多,品种增产优势不强,布局不合理;农业投资减少,稻田抗灾能力减弱;新技术推广速度慢,是造成早稻单产徘徊的主要原因。要迅速扭转早稻单产徘徊局面,需要进一步发挥早稻品种增产潜力,增加农业投入,提高抗灾能力,采取有效措施,培肥地力,加快新技术推广力度。
Disastrous weather is more and the advantages of yield increase are not strong and the layout is irrational. The decrease of agricultural investment and the reduction of disaster-resistance capability of paddy fields are the main reasons causing the shortening of new rice production. In order to quickly reverse the situation in which the yield of early rice is stagnating, it is necessary to further develop the potential for increasing the yield of early rice varieties, increase agricultural input, improve disaster resilience, take effective measures to cultivate fertility and accelerate the promotion of new technologies.
