水稻的穗部参数水稻的穗部性状是构成产量的重要因素,合理的穗型结构不仅能增加每穗的总粒数,而且能够提高成粒率和籽粒的饱满程度,合理的穗型结构也能够更好地利用光能和增强对病虫的抵抗能力。在过去的研究工作中,除对穗粒数、粒重和结实率的研究外,对其他性状则很少研究,例如稻穗的着粒密度,穗支梗的数目、长度,穗子的弯曲程度等,这些性状在育种工作和高产栽培中都具有重
The panicle parameters of rice is an important factor of rice yield. Reasonable panicle structure can not only increase the total number of panicle per panicle, but also increase the rate of granulation and the fullness of grain. The reasonable panicle structure Better use of light energy and increased resistance to pests and diseases. In the past research work, except for the study of grain number, grain weight and seed setting rate, few studies were conducted on other traits, such as the grain density of rice, the number and length of ear stems, the degree of bending of ear Etc., these traits have great importance in breeding and high-yielding cultivation
