| 摘 要： | 研究了不同施肥和株行距处理对王草生产性状的影响,结果显示:所有施肥处理中,以处理FT5(尿素150 kg/hm2.a+复合肥300 kg/hm2.a)效果最好,说明N、P、K 3元素互作效应高于N元素单效应,平衡施肥有利于王草的分蘖和干物质的积累,可提高王草的个体鲜重和鲜草产量;株行距对王草的生产性状也产生显著影响,株行距太小,不利于王草的生长,试验表明最佳株行距处理DT4(行距×株距为70 cm×50 cm),在此株行距下,王草各项生产性状均极显著(P<0.01)地优于其他处理。

| Abstract: | The effect of fertilization,row and individual space on the productive characters of King grass(Pennisetum americanum×P.purpureum)was studied and the results indicated that: The treatment FT5(150 kg urea + 300 kg NPK compound fertilizer hm~2/a per ha per year) showed the best performance among all fertilization treatments.And the fresh weight of individual plant was 667.58 g,the fresh yield could reach(394238.0) kg/hm~(2)·a.This suggested that the effect of interaction among N,P and K was stronger than that of sole N.The row space and individual space also affected the productive aspects and the results showed that the best treatment was 70 cm of row space and 50 cm of individual space,and the production related indices were significantly higher than other treatments(P<0.01).The fresh weight of individual plant was 769.42 g and the fresh yield was 380350.0 kg/hm~(2)·a. |
