日本的中国农业试验坊在直播水稻试验田里,采用密植少肥栽培法,获得每亩906斤糙米的高产记录。试验田播种的密度为每平方米417粒种子,每亩的播种量为16斤,平均每平方米有83.3个穴,每穴播5粒种子,株行距离为12×10厘米。种子的发芽率为80％,这样,即使在分蘗期不施追肥,也能保证每粒种子抽一个穗。因此,每平方米可有450—500个穗,从而确保
Japan’s China Agricultural Experiment Square in the direct-seeded rice experimental field, the use of close planting less fat cultivation method, access to 906 kg of brown rice per mu high yield record. The experimental field sowing density of 417 seeds per square meter, seeding per acre of 16 kg, an average of 83.3 holes per square meter, sowing five seeds per hole, line spacing of 12 × 10 cm. Seed germination rate of 80%, so that even in the tillering stage without topdressing, but also ensure that each seed pumping a spike. Therefore, there are 450-500 spikes per square meter to ensure
