化控栽培技术对玉米抗倒性和产量的影响
The Effects of Lodging Resistance and Yield on Maize Chemical Regulation Cultivation Techniques
摘要
Abstract
Danyu336 was chose as material to study the effects of chemical regulation on maize lodging resistance and yield under different density.The results showed that highest yield was up to 13 736.6 kg/ha in the density of 75 000 plants/ha under the condition of chemical regulation,the yield was more than the conventional planting in the 75 000 plants/ha density,the yield presented significant differences between chemical regulation with conventional planting in the plant density of 75 000 plants/ha and 90 000 plants/ha.It's happened lodging rates 38.5％ under the density of 75 000 plants/ha by conventional planting while the chemical regulation wan not;serious lodging rates 84.6％ by conventional planting under the density of 90 000 plants/ha,but the chemical regulation was only at 35.8％,compared with 48.8％ less.It showed that chemical regulation could effectively reduce the plant height,ear height and the height of the center of gravity,optimizing plant type,to a certain extent,improve the quality of stem traits,enhance the capacity of resistance to lodging,enhance the capacity of the field ventilation pervious to light,improve photosynthetic ability and the accumulation of dry matter production under mid-high density condition.关键词
