目前常规水稻品种是通过单株选育的,而大面积栽培上却以丛插为主。那么,自然就存在这样一个问题:选什么样的单株才能在丛插条件下表现良好?单株栽培与丛插栽培有什么关系?我们于1983年开展了本项研究。 材料和方法 用桂朝2号、广二矮104及基本稳定的品系共23个。采用成对比较设计,分为单、丛两种栽培方法,均为5×6寸,小区12×20穴,除去二行边行后计产。考察了单产、穗长、每穗总粒数、结实率、千粒重、单株穗数、全生育期、成穗率、谷草比、抽穗期和成熟期叶指、抽穗期地上干重、透光率、剑
At present, conventional rice varieties are bred by individual plants, while large-area cultivation is dominated by plexus plugging. So, naturally, there is such a question as to what kind of plant should we choose to perform well under the conditions of cluster planting? What is the relationship between single plantation and cluster cultivation? We conducted this study in 1983. Materials and methods used Gui Chaow 2, Guang Er short 104 and basically stable strains of a total of 23. Paired comparison design, divided into single, Cong two cultivation methods are 5 × 6 inch, 12 × 20 cells, remove the two lines after the line production. The effects of yield per plant, spike length, total grains per panicle, seed setting rate, 1000-grain weight, spike number per plant, whole growth period, spike rate, aspartate ratio, leaf index at heading and maturity stage, Rate, sword
