大田作物的田间整齐度,包括植株在田间分布的均匀性和植株个体间性状差异两方面。田间分布的均匀度与作物对肥水和光能的利用有关,而个体性状整齐度的差异则与产量性状有关。对于稻、麦等分蘗性作物的群体整齐度可以通过肥水调控达到部分补偿,而目前的玉米栽培种绝大多数为单茎单穗类型,自我调节能力较弱,所以生产中一向强
The field uniformity of field crops includes the uniformity of plant distribution in the field and the difference in traits among plants. The uniformity of field distribution is related to crop utilization of fertilizer and light energy, while the difference in individual uniformity is related to yield traits. For rice, wheat and other bushy crops group uniformity can be partially compensated by the regulation of fertilizer and water, and the vast majority of the current corn cultivars are single stems and spikes, self-regulation ability is weak, so the production has always been strong
