日本米丘林学会在苏联方形簇播的先进经验的启发下,总结了本国老农的水稻方形簇播密植的栽培方法,并进行试验,一般都获得增产,如能结合集中施肥,其增产效果更为显著。日本“米丘林农业”报等进步报刊不断介绍这一先进栽培方法的成果。水稻方形簇播(巢植法)的栽培样式,一般是按正方形1尺5寸左右距离分成若干簇;每簇种植4穴(丛),穴间距离2—3寸;每穴种植1—3株,如图1。也有每簇种植3穴或5穴的,方法如图2。兹介绍几个试验结果于下: 一.日本秋田县北秋米丘林学会泽田一义 1955年水稻方形簇播试验 1.栽培样式:共分7个处理 (1)点播(春化15 Inspired by the advanced experience of cluster planting in the Soviet Union, the Japanese Michurin Society summarized the cultivation methods of paddy planting and planting close planting of its own peasants in the country. In general, they all increased production. If they combined concentrated fertilization, the yield increase was more For the obvious. Japan’s “Michurin Agriculture” and other progressive newspapers continue to introduce the results of this advanced cultivation methods. Rice square planting (nest planting method) cultivation style, is generally divided into square clusters of about 1 foot 5 inches; each cluster planting 4 points (plexus), the distance between holes 2-3 inches; Strain, as shown in Figure 1. There are also three or three clusters of planting points, the method shown in Figure 2. Here are a few test results in the following: I. Akita Prefecture in Akita Prefecture in Japan learned Sawada Yoshida 1955 rice square cluster test 1. Cultivation style: Divided into seven treatment (1) on-demand (vernalization 15
