| 摘 要： | 用五个具有不同穗型特点的小麦品种(系)进行不同密度的比较试验,结果表明:只有群体合理,才能使穗、粒、重得到协调发展,获得最佳产量。在相同栽培条件下,品种间对密度要求大体趋势一致。但因品种特性的差异,对密度要求并不完全相同,各有其侧重的穗、粒、重适宜范围。

| Abstract: | The experiment on planting density in 5 wheat varieties with different ear shapes was carried out.The results showed that only the population of wheat plants was suitable and the number of ears and grains,weight per 1000 grain was coordinated,could the hightest grain yield be obtained.Under the same cultivation the demand to density of each variety was almost similar but not complete identical.Therefore,in order to form the suitable structure of wheat population,it was necessary to keep the number of ears and grains,weight per 1000 grain of each variety a proper range. |
