栽植方式和品种对杨树林下麦冬分蘖株数的影响

Impact on the number of tiller of Liriope spicata with the different planting manners and varieties under the poplar woodland

在郁闭后的杨树林下进行麦冬不同品种、不同栽植方式试验。1年的试验结果表明:中叶麦冬分蘖株数最多,达45株/m2;栽植方式为3株/丛时,其分蘖株数最多,达62株m2;适当密植有利于分蘖,栽植密度为10 cm×10 cm时,其分蘖株数最多,达102株/m2;根系长度对分蘖株数的影响不明显。

The test on different varieties of Liriope spicata and different planting manners in the close woodland of poplar was conducted,the one-year test results showed that,the tiller with the moderate leaf of Liriope spicata was the most in all varieties,the number of tiller was up to 45 plants per square meter. The tiller with of 3 plants per plexus was the most in different planting manners,the number of tiller was up to 62 plants per square meter. Close planting was beneficial to tillering,with the planting density of 10 cm × 10 cm,the number of tiller was up to 102 plants per square meter. Root length was not obvious influence on the number of tiller.
