当归玉米套种栽培模式研究

On cultivation patterns of Chinese angelica's interpolating with maize

春播秋收的当归 ,因生长季节短 ,草荒等原因 ,产量低。夏播二年秋收 ,幼苗因受日灼 ,成活少。将当归夏季与玉米套种 ,能有效克服日灼 ,二年秋季收获 。

The effects of sowing and harvest fime,cultitating in combination with maize on plant growth and yield of An-gelica sinennsis were studied.The results indicated that seeding in summer and harvesting in nest autumn and cultivating in combination with maize in summer resulted in the best plant growth and highest yield.When the culture tims was the same but without the combination with maize ,the sprout could hardly survive summer as the result of scorch.Sowing in spring and harvesting in autumn,resulted in lower yield because of the shorter growth span and mass of weeds.
