七十年代初,我们在水稻矮化育种工作的基础上提出了丛生快长类型品,种选育的设计思想,经十多年的育种实践,一批“丛生快长”的新良种在生产上收到较大的经济效益。为了探讨丛化类型品种增产原理,本研究对3种不同类型的4个品种的产量构成因素及其群体内透光率变化作了观察分析,现报告试验结果如下。一、试验材料与方法供试品种类型:典型矮化类型品种“珍珠矮11号”和“朝阳早18号”;典型丛化类型品种“双桂36号”;介于矮化和丛化的中间类型品种“桂朝2号”。
In the early 1970s, on the basis of the dwarf breeding work in rice, we put forward the design idea of growing and growing long types of varieties and varieties. After more than ten years of breeding practice, a batch of new varieties of “ On the receipt of greater economic benefits. In order to explore the principle of yield increase of plexiform types, we observed and analyzed the yield components of three different types of four cultivars and their transmissibility. The results of the test are as follows. First, the test materials and methods to test the types of cultivars: typical dwarf varieties ”pear short 11“ and ”Chaoyang early 18“; typical plexiglass type ”Shuang Gui 36“; between the dwarf and pied The middle type breed ”Gui North 2".
