| 摘 要： | 试验表明,施肥对高粱杂交草的生长及干物质积累影响显著.不施氮肥的高粱杂交草植株细小,叶片黄化,老叶提早脱落;施氮植株茎杆粗壮,叶色浓绿,但易于遭受虫害.施用氮肥能极显著地增加高粱杂交草的株高,在不施氮肥的情况下,施用磷肥则对株高有抑制作用.氮肥也是影响高粱杂交草干物质积累的主要因素,施用氮肥的各处理干物重均极显著高于不施氮的处理.

| Abstract: | The Effects of fertilizer on the growth and dry weight of sorghum hybrid grass were studied by pot experiment. The results show that: (1) the plant of sorghum hybrid grass no applied fertilizer N was thin and small, the leaves were yellow, and the old leaves early fell off. The plant applied fertilizer N was strong and big, the leaves were deep green, but were easy to be harmed by injurious insects. (2) Applying fertilizer N was enable to rise notably the plant height of sorghum hybrid grass, applying fertilizer P could pent up the increasing of the plant height of sorghum hybrid grass on the condition of no applying fertilizer N. (3)Fertilizer N was the most major factor effecting the accumulation of sorghum hybrid grass dry matter, the dry weight of all of the treatments applied fertilizer N were notable higher than those no applied fertilizer N. |
