晋中麦后不同苗龄移栽对玉米生长及产量的影响

Effects of Transplantation at Different Seedlings Age to Maize Growing and Yield after Winter Wheat Harvesting in Central Shanxi

在山西晋中冬麦区,利用秸秆育苗钵进行不同苗龄麦后移栽玉米试验,对夏玉米的生长、产量进行了研究。结果表明,在充分利用现有的光热资源条件下,利用秸秆育苗钵育苗,在幼苗二叶一心和三叶一心的苗龄下移栽玉米,可以实现早栽培、延长玉米有效生育期,使中晚熟玉米可以正常成熟,从而提高当地玉米产量。

In winter wheat region of Central Shanxi, straw seedling pot was utilized in maize seedling transplantation after winter wheat harvesting to research the effect to the growth and yield of the summer maize. The results indicated that： under the conditions of complete utilizing existing light and hot resources, transplanting the maize under the seedling age of 2-1eaves and 1- heart or 3-1eaves and 1-heart and culture the seedlings in straw seedling pot, it will realize forcing cultivation and extend the valid breeding time of the maize to make sure the late-maturing maize mature on time and increase yields of local maize.
