今年我区各县单季稻面积将扩大,这关系到全年的粮食生产.为此,在重新学习陈永康同志单季稻高产经验的基础上,就我所近年来单季稻苏粳2号高产栽培的实践,结合近期面上的调查,初步分析如下.一、千斤丰产田的主要特点1.丰产田的穗粒结构 苏粳2号是一个分蘖力中等,株型紧凑,植株清秀,比较耐肥的晚粳类型品种.产量构成因素中,千粒重变化较小,一般保持在27克左右.高产栽培,必须在保证足够穗数的基础上,主攻大
This year, the area of single-season rice will be expanded in all counties in our region, which is related to the annual grain production.Therefore, on the basis of re-studying Comrade Chen Yongkang’s high-yielding single-season rice production experience and on the practice of high-yielding cultivation of single-cropping rice system Sujing No.2 in recent years, A recent survey of the surface, the initial analysis is as follows.I, the main characteristics of a thousand kilograms of high yield field 1. Spike grain structure of high yielding fields Sujing No. 2 is a mid-tillering ability, compact plant type, more resistant to late Japonica type Varieties.Production components, grain weight changes smaller, generally maintained at about 27 grams.High-yielding cultivation, must ensure that sufficient number of ears, based on the large
