摘要
以阿尔冈金为供试材料,研究施肥对苜蓿Medicago sativa营养成分的影响。粗蛋白和粗纤维的含量是衡量牧草品质的2个重要指标。结果表明营养成分含量并不随肥料施入量的增加而增加,粗蛋白和粗脂肪的含量开花期高于成熟期,粗纤维和粗灰分的含量开花期低于成熟期。试验测得尿素施入量为1 206.5kg/hm2、过磷酸钙施入量为907.8 kg/hm2、不施硫酸钾时粗蛋白和粗纤维的含量达国家一级标准。
Using Argangjin as the experimental material, the effect of fertilizer on the nutrition of alfalfa was studied. Contents of crude protein and crude fiber were two important indexes to evaluate the quality of the forage. The results showed that the nutrient content was not to increase with fertilizing increase, contents of crude protein and crude fat was higher in flowering period than mature period, and contents of crude fiber and crude ash was lower in flowering period than mature period. The experiment showed that the contents of crude protein and crude fiber reached the 1st level of the state＇s standards when urea fertilizing 1 206.5 kg/hm^2, super calcium phosphate fertilizing 907. 8 kg/hm^2 and no potassium sulphate.
