研究表明,在总头数与预期穗数相等的有效分蘖终止期,采取深中耕与镇压相结合的控制措施,可使有效分蘖与无效分蘖间形成一个“断档”阶段,拉大有效生育与无效生育的距离,减少无效生产,提高有效蘖整齐度,促进根系发育,协调群体与个体的矛盾及地上部生长与地下部生长的矛盾,明显改善群体质量。这项措施提高了分蘖成穗率,增强了植株抗倒伏能力,降低了群体对个体的制约,干物质生产和源库关系更趋合理,产量和经济系数显著提高,是小麦高产、超高产综合配套技术的一项核心内容。
The research shows that the control measures of the combination of deep tillage and suppression can make the stage between “effective stalling” and “ineffective tillering” form an “off-stage” in the effective termination of effective tillers whose total number of heads is equal to the expected number of spikes, The contradiction between the growth of population and the growth of the underground part and the improvement of the quality of the group obviously. This measure increases the tillering rate, enhances the lodging resistance of plants, reduces the population restriction to the individual, makes the relationship between dry matter production and source and sink more reasonable, and significantly increases the yield and economic efficiency. It is a result of high yield and super high yield synthesis of wheat A core element of supporting technology.
