不同苗龄玉米苗对垄上栽植机的适应性探讨

Adaptability Study on Different Ages of Corn Seedlings during Transplanting by The Ridge Planting Machine

试验比较了苗龄在1叶至5叶期间的甜玉米苗用机械移栽的效果以及植株生长情况和产量情况。结果表明:1叶1心至3叶1心期间的苗均试用于机械移栽,并且产量较高;4叶以后的大苗不仅容易造成机械损伤,而且成苗情况和产量情况均不理想。在试验条件下,推荐1叶1心至3叶1心苗进行机械移栽。

The study compared the effects of sweet corn seedlings which age from 1 leaf to 5 leaves during mechanical transplanting as well as the plant growth and yields. The results showed that the seedlings aged from 1 leaf to 3 leaves were all adapted to the mechani- cal transplanting, and the yields was higher, the seedlings older than 4 leaves not only cause mechanical damage likely, but also the seedling itself and the yields are not ideal. Under the conditions of the experiment, the seedlings which aged from 1 leaf to 3 leaves were recommended for mechanical transplanting.
