众所周知,皮棉产量是由密度×单株铃数×单铃子棉重×衣分构成的。单株铃数是构成棉花产量的因子之一,它与密度构成亩铃数。由于品种和栽培技术条件的不同,单株铃数在近似密度下,变动幅度是比较大的。亩铃数的多少,在很大程度上对产量有决定的影响。因此,单株铃数是产量构成中最重要的因子,也是品种和栽培试验中的重要记 It is well-known that lint yield consists of density × number of bolls per plant × weight of boll cotton × crop. The number of bolls per plant is one of the factors that make up cotton yield. Due to the different varieties and cultivation techniques, the number of bolls per plant in the approximate density, the change is relatively large. Mu number of bells, to a large extent, have a decisive impact on production. Therefore, the number of bolls per plant is the most important factor in yield composition and is also an important marker in varieties and cultivation trials
