木质素作为尿素控释材料对小麦氮肥利用效果的研究

Lignin Used as a Controlled-release Material of Urea in Nitrogen-utilized Effects for Wheat

采用小麦盆栽试验方法,进行了利用木质素作为尿素控释材料对作物生长作用和提高氮肥利用率的研究。结果表明,在相同供氮量条件下,与纯尿素处理比较,添加一定数量木质素,不仅加速小麦营养生长,提高结实率,促进粒数膨大,达到增产效果;而且能较大幅度地提高氮肥利用率。

A pot experiment grown wheat in which lignin was used as a controlled-release material of urea,it was conducted to research the effects on growth and nitrogen-utilized effects of wheat.The result showed that a few lignin could not only increase wheat yield and nutrition growth,improve seeding rate,enlarge fruit,but also improve nitrogen-utilized efficiency at large scale.
