一、产量构成据近几年在苏州、无锡两市大面积示范结果,机插水稻一般亩产在500公斤以上,基本同手插大苗持平。高产单位及丰产方亩产550～600公斤,高产田块达656.5公斤。又从11组对比试验田块考种核产表明,机插水稻较常规水稻亩穗数增9.7%,每穗粒数减少8.3%,增穗所得略大于穗形减少所失,平均亩产增5.7%。从蓉南村及换新村近百块典型田块及试验的产量和穗粒结构资料分析表明,机插水稻高产,与以下几个因素有关:
I. Composition of Output According to the large-scale demonstration results of the two cities in Suzhou and Wuxi in recent years, the average output of machine-inserted rice is above 500 kg. High-yielding units and high-yielding side mu produce 550 ~ 600 kilograms, high yield plots of 656.5 kilograms. In addition, the results of field test showed that the average number of grains per spike increased by 9.7% and the number of grains per panicle decreased by 8.3%. The increase of ear production was slightly larger than the decrease of spike shape, and the average yield per mu increased by 5.7% %. The analysis of yield and grain-ear structure data from nearly 100 typical plots and trials in Rongnan Village and Xuanxin Village shows that the high yield of machine-inserted rice is related to the following factors:
