经4年来对太湖糯的研究,结果表明:太湖糯的产量随源或库的增加而提高,比较两者的效应以后者为大,其源、库特征当属源库互作型,但偏向于库限制型。据此,提出了以扩库为基础、以强源作保证的扩库强源高产栽培对策。在亩颖花量、结实率及千粒重这三个产量构成因素中,对产量的作用以亩颖花量最大,从而提出了稳穗增粒的高产主攻途径。依据对栽培特性的深化认识与其技术效应的综合分析,提出了实行与温光同步的适期播栽法、确定高光效群体的适宜起点、建立高产的肥水促控技术、采取有效的综防措施等四项相配套的技术关键。结合大面积生产的实际和以上研究的结果,制订了高产技术规范,经应用验证,增产显著,效益明显。
After four years of research on Taihu waxy rice, the results showed that the yield of waxy Taihu Lake increased with the increase of source or sink, while the latter was larger than the latter. Limited to the library. Based on this, a new countermeasure for high-yielding and high-yielding cultivation with strong source was put forward based on expanded basement. Among the three yield components of grain yield, seed setting rate and grain weight per hectare, the effect of grain yield on the yield of grain was the highest. According to the comprehensive understanding of the cultivation characteristics of the deepening awareness and technical effects, put forward the implementation of the appropriate temperature and light sowing method to determine the appropriate starting point for high light efficiency groups to establish high-yield fertilizer to promote control technology to take effective comprehensive preventive measures And other four supporting the technical key. Combined with the actual production of large-scale production and the results of the above research, developed high-yielding technical specifications, the application of proven, significant yield increase, significant benefits.
