遮阳对果园生草繁缕生物学特性的影响

Effects of Shading on Biological Characteristics of Stellaria media(L.) Vill. in Orchard Grassing

以繁缕为试验材料,研究不同程度遮阳(65%,95%)处理下,繁缕的营养生长及生命周期变化。结果表明,遮阳率达到95%时,繁缕营养生长明显好于自然光照条件,且枯黄期晚于自然光照13d。综合分析表明,繁缕耐阴性极强,适合密植果园生草栽培,尤其适合目前的乔砧密植成龄果园。

This study used Stellaria media(L.) as material, the vegetative growth and life cycle changes of Stellaria media(L.) were studied under different degrees of shading treatment(65%, 95%). The results showed that when the shading rate reached 95%, the nutrient growth of Stellaria media(L.) was significantly better than that of under natural light conditions, and the wilt period was 13 d later than that of under natural light. The comprehensive analysis shows that shade tolerance of Stellaria media(L.) is good, which is suitable for herbage cultivation in dense orchard, especially for mature orchard with tree rootstock dense planting.
