水稻每亩的栽插穴数和基本苗数,是构成水稻群体的基础。为了给生产上进行合理密植提供依据,我们于1982～1983年进行了栽插密度与建立高光效群体结构关系的研究。现将研究结果报告如下: 材料与方法 试验在我院进行,以汕优3号工厂秧为材料,5月10日进行温室播种立苗,5月12日田间绿化炼苗,5月25～29日栽插。栽插密度分三个处理:Ⅰ.每亩2万穴,基本苗2.8万,叶龄3.4;Ⅱ.每亩1.5万穴,基本苗2.3万,叶龄4.0;Ⅲ.每亩1.2万穴,基本苗
The number of planting holes per acre and the basic seedlings per acre are the basis for forming rice groups. In order to provide a basis for rational and close planting in production, we conducted a study on the relationship between planting density and the establishment of high light efficiency population structure from 1982 to 1983. Now the research results are reported as follows: Materials and methods in our hospital test to plant material Shanyou 3 for the material, May 10 for planting seedlings in the greenhouse, field greening on May 12 Lian Miao, May 25 to 29 Day planted. Planting density in three treatments: Ⅰ. 20,000 acre per acre, basic seedlings 28,000, leaf age 3.4; Ⅱ 15,000 acre per acre, basic seedlings 23,000, leaf age 4.0; Ⅲ. 12,000 acre per acre, Basic seedlings
