1958年农业生产大跃进的经验证明,密植能充分利用地力、空气和阳光,在单位面积内获得较多的穗数和粒数,增加产量。密植后本田用种量大,所用的秧田面积也大。如孝感县58年双季晚稻一般插3×4寸,每穴4—6苗,每亩用种20斤以上。如以每亩播种80斤计算,则1亩秧田只能栽4亩本田,这样产生了稀播与占用秧田面积太大的矛盾。近2—3年来,湖北省农业科学研究所和各地试验证明;采用迟熟早、中粳稻,如早粳16号、
The experience of the Great Leap Forward in Agricultural Production in 1958 proves that close planting can make full use of geo-force, air and sunshine and obtain more spikes and grains per unit area to increase output. Honda dense seed after planting, the area used is also large seedling. For example, Xiaogan County 58-year double season late rice generally inserted 3 × 4 inch, 4-6 holes per hole, with 20 kg per mu or more. If planting 80 kg per acre basis, then 1 mu of seedlings can only planted 4 acres of Honda, resulting in a thin sowing and occupation of seedling area too much conflict. Nearly 2-3 years, Hubei Academy of Agricultural Sciences and around the test proved that the late maturity, middle japonica rice, such as early japonica 16,
