百喜草营养动态初探

Preliminary Research on the Nutritional functions of Paspalum Notatum Flugge

本文对水土保持草被植物百喜草的营养动态进行了初步研究。结果表明,其蛋白质、脂肪、碳水化合物及钙磷等养分含量丰富,百喜草苗期营养价值最高,但鲜草产量低;进入旺长期后,枝繁叶茂,鲜草产量迅速提高,养分含量也较高,是作青饲料的最好时期。如用作青贮或晒制干草粉应在抽穗初期进行。

The nutritional functions of Paspalum notatum flugge which is a plant for water and soil con- servation was investigated preliminarily.It showed that the quanlitity of protein,fat,carbohydrate,Ca and P in the plant were plentiful.,In seeding period its nutrition was maxium,while fresh grass output was low. After fast growth period,fresh grass output incrased rapidly with higher nutrition contents.It,was the best chance as fresh forage.production of silage or huy powder should be carried out in the begining of heading stage.Paspalum notatum flugge was a good kind of forage grass with water and soil conservantion function..It could play an important role inin current quiting plough to plant trees and grass,developing animal husbandry in Guizhou province.
