我县水稻插植方式,与其它地区一样,通常采用近方形(株距接近行距)插植。随着插植密度的提高,行距随之缩小,使水稻生长中个体与群体的矛盾突出,田间荫蔽度增大,病虫害加重,操作困难等。为了解决这些问题,国内不少地区和单位正在探索大行距栽培方式,并获得了不同程度的增产。我们在去年早稻生产中,为了使生育中期施用厩肥操作方便,采用了加大行距(由通常的5寸加大到8寸)、缩小株距(由4～5寸缩小到2.5寸左右),不减少
Rice planting methods in our county, like other regions, usually adopt near square planting distance. With the increase of planting density, the row spacing will be reduced, the contradiction between individuals and groups in rice growth will be prominent, the field shade will increase, pests and diseases will increase, and the operation will be difficult. In order to solve these problems, many areas and units in China are exploring ways of cultivating large-scale investment and gaining different degrees of increase in production. In the rice production last year, in order to facilitate the application of manure during mid-term growth, we increased the spacing (from the usual 5 inches to 8 inches) and narrowed the spacing (from 4 to 5 inches to 2.5 inches) cut back
