近年,由于玉米田间施肥量的增大、施药种类及次数增多、种植密度增大、环境条件及气候的变化等因素,造成大田种植玉米的分蘖增多。本文对玉米的分蘖生理、影响因素进行了概述,对分蘖与玉米产量的关系进行初步探讨。1玉米的分蘖生理特性稻麦分蘖是有益的,可以增加穗数并提高籽粒产量。玉米分蘖与玉米产量之间的相互关系是近年存在争议的问题。普遍认为,分蘖吸收营养造成减产,应将分蘖拔除。经大量实验证明,玉米分蘖不但对玉米产量没 In recent years, due to the increase of fertilizers in corn field, the types and frequency of pesticides increased, planting density increased, environmental conditions and climate changes and other factors, resulting in increased corn tillering in the field. In this paper, we summarized the tiller physiology and its influencing factors, and discussed the relationship between tiller and corn yield. 1 Tillers Physiological characteristics of rice Tillering rice and wheat is beneficial, can increase the number of ears and increase grain yield. The correlation between tillering of maize and corn yield is a controversial issue in recent years. It is generally accepted that tillers can absorb nutrients to reduce production, and tillers should be removed. After a large number of experiments show that corn tiller not only corn production did not
