摘要
为探明甬优1540作连作晚稻种植的高产栽培技术途径,汇总整理了 2016-2021年浙江省各地共69组甬优1540作连作晚稻种植的有效穗数、每穗总粒数、结实率、每穗实粒数、千粒重和产量数据,比较了甬优1540不同产量水平的产量及其构成因素差异.结果表明,甬优1540作连作晚稻种植的高产栽培技术途径为注重有效穗数和每穗实粒数的提高,争取穗、粒兼顾,协调穗、粒结构,提高结实率,在此基础上发挥千粒重的增产作用,从而构建起整体协调的产量结构,促进高产.
Abstract
To explore the high-yielding cultivation technology for Yongyou 1540 planted as double-cropping late rice,the data on effective panicle number,the number of total spikelets per panicle,seed setting rate,the number of filled grains per panicle,1 000-grain weight and yield were collected and analyzed from 69 groups of Yongyou 1540 grown as double-cropping late rice in different regions of Zhejiang Province from 2016 to 2021,and the yield and its components at different yield levels of Yongyou 1540 were compared.The results showed that the high-yielding cultivation approach for Yongyou 1540 was to pay high attention to increase of effective panicle number and the number of filled grains per panicle,strive for the balance between panicle and grain number,coordinate panicle and grain structure and improve the seed setting rate,and on this basis,play the role of yield increasing effect of 1 000-grain weight,so as to build the overall coordinated yield structure and achieve high yield.
