通过随机区组试验,研究分蘖对玉米生育期、农艺性状及产量的影响。结果表明:保留分蘖的黄玉米植株与掰除分蘖的黄玉米植株相比,主茎穗数相差不大,但是主茎单穗重、鲜籽粒重增加,产量增加4.29%。水果玉米在不去分蘖条件下,因部分分蘖的成穗,单株产量较不去分蘖产量增产12.36%。因此,玉米苗期分蘖对生育期没有影响,但可以降低玉米株高和结穗高度,使茎秆增粗,叶面积增大。玉米生育期不去分蘖有利于主茎穗穗重及穗粒重增加,产量提高。
Randomized block experiments were conducted to study the effects of tillers on the growth, agronomic traits and yield of maize. The results showed that the number of spike of main stem was similar to that of yellow corn with tillering tillering, but the weight of main stem with single spike and kernel weight increased by 4.29%. Fruit corn without tillering conditions, due to the partial tillering ear, yield per plant less tiller yield 12.36%. Therefore, tillering of maize seedling stage has no effect on the growth stage, but can reduce the corn plant height and the height of the ear, make the stem thicker, the leaf area increases. Not tillering during the growth of corn is conducive to the main stem spike weight and grain weight increase, yield increased.
