不同种肥施用水平对大果沙棘苗期生长的影响

在西宁地区采用裂区设计将不同品种沙棘种植于不同种肥用量下进行实验结果表明：中华沙棘在其株高、根长、根茎、干重四项指标的测定中均高于向阳、楚伊两个大果沙棘品种。在300 kg/hm^2的施肥水平下,大果沙棘的苗期株高、根长、根茎、干重生长量最大。品种和不同磷酸二氨的施肥量的互作显著,中华沙棘在低肥条件下的生长量大,在高肥条件下向阳、楚伊的生长量大。

Effect of Different Fertilization Levels on Seedling Growth of Big Fruit Seabuckthorn

Experiments were carried out by using split-plot design in Xining with different varieties of seabuckthorn cultivated under different fertilization levels.Results showed that the Chinese seabuckthorn showed better parameters of height,length of root,diameter of root and dry weight than varieties of Xiangyang and Chuyi.With the fertilization level at 300 kg/hm2,big fruit seabuckthorn showed the best parameters in height,root length,root diameter and dry weight of fruit.Fertilization levels of diammonium phos...
