播量、穴栽插本数、分蘖发生时期、植伤诸因素均显著影响穗型质量,分蘖发生时期最为突出。一次分蘖节位、二次分蘖见蘖期分别与穗总粒数、穗粒重显著相关,随着分蘖节位每升高1个和见蘖期推迟3d,穗总粒数减少7.66~21.71粒;穗粒重降低0.15~0.41g。综合粒、重等因素,穗质量为主茎>第1节位分蘖>秧田期一次分蘖>本田一次分蘖>二次分蘖。提高穗质量除稀播培育多蘖壮秧外,要以促进低节位分蘖和同伸的二次分蘖早生快发为重点,其次要控制9节位以上分蘖及其同伸的二次分蘖发生
Sowing quantity, the number of acupoints inserted, the time of tillering, and the factors of plantation all significantly affected the quality of panicle type, and the tillering stage was the most prominent. The first tillering node and the second tillering at the tillering stage were significantly correlated with the total grain number per panicle and the grain weight per ear. As the tillering node increased by 1 and the tillering stage by 3 days, the total grain number decreased by 7.66 ~ 21.71 grains; Spike grain weight decreased 0.15 ~ 0.41g. Comprehensive grain, heavy and other factors, the quality of the main stem spike> Section 1> tillering> seedling stage of a tiller> Honda primary tiller> secondary tillering. To improve the quality of the ear except for thinning and cultivating more tiller seedlings, to promote the low node tillering and extension of the secondary tillering early rapid onset as the focus, followed by the control of more than 9 nodes tillers and its secondary elongation occurs
