日本在1977年3月出版的《农业技术大系》作物编第3卷中,收集了50篇文章,分别介绍了1975—1976年日本不同农区50家水稻高产农户的典型经验。其中有36户一季亩产稻谷超千斤。他们的产量分别为,亩产1,000—1,100斤的14户,1,100—1,200斤的10户,1,200—1,300斤的7户,1,300—1,400斤的2户,1,400斤以上的2户。另有1户是日本中部滋贺县的小西丰,产量最高,1976年30亩,平均亩产1,603斤。本着“洋为中用”的精神,本文着重就亩产1,200斤以上12家农户的有关栽培技术,从如下四方面进行介绍,并稍加评论。一、关子本田用种量,栽插密度和产量构成12家亩产稻谷1,200斤以上的高产农户,每亩本田用种量为1.5—8斤。其中以单本插取得高产
In Volume 3 of Japan’s Major Agricultural Science and Technology Series, published in March 1977, Japan collected 50 articles describing the typical experiences of 50 high-yielding rice farmers in different agricultural areas of Japan from 1975 to 1976. Among them, 36 are super rice in the first quarter with a super-yield. Their output was 14 households of 1,000-1,100 kg per mu, 10 households of 1,100-1,200 kg, 7 households of 1,200-1,300 kg, 2 households of 1,300-1,400 kg and 2 households of 1,400 kg or more. Another one is Xiaoxifeng in Shiga Prefecture, central Japan, with the highest output. In 1976, it was 30 mu, an average of 1,603 kg per mu. In the spirit of “foreign-oriented”, this article focuses on the cultivation techniques of 12 households of more than 1,200 catties per mu, which are introduced from the following four aspects with a little comment. First, shut Honda with seed, planted density and yield constitute 12 acres of rice more than 1,200 pounds of high-yielding farmers, the amount of hm per mu for the 1.5-8 kg. Among them, a single high yield was inserted
