农桐间作,会不会发生泡桐与小麦争光的矛盾呢?这是人们最关心的问题,近几年,我们带着这个问题,在商丘地区农桐间作田作了大量的光照强度观测,从获得资料看此问题有了肯定的答案:夏播作物因生长季正处在盛夏,此时泡桐枝叶繁茂,由于泡桐遮荫而表现为有争光现象,造成夏播作物有不同程度减产。而麦桐间作,由于泡桐和小麦的生育周期是错开的,两者基本上不存在争光现象。不仅如此,农桐间作还为小麦创造了良好生态环境,间作地小麦与对照地小麦相比都表现有明显的增产.
Agropyral intercropping, there will be the contradiction between Paulownia and wheat glory it? This is the people are most concerned about the issue, in recent years, we took this issue, in the Shangqiu area Intercropped with inter-cropland Tian made a lot of light intensity observations from Access to information to see this issue with a positive answer: Summer sowing crops due to the growing season is in midsummer, at this time foliage lush foliage, due to paulownia shade showed a win glory, resulting in summer sowing crops have different degrees of yield reduction. Intercropping wheat, because the Paulownia and wheat fertility cycle is staggered, basically there is no glory between the two phenomena. Not only that, Agropyral intermediary also created a good ecological environment for wheat, intercropping wheat compared with the control of wheat have shown significant increase.
