喀斯特高原山区蓖麻施肥量对产量性状的影响
Effect of Fertilizing Amount on Yield Traits of Castor in Karst Plateau Mountainous Area
摘要
Abstract
Using Zibima No.7 as the test material, we set up seven fertilizer (N, P2O5, KCl) application amount treatments by randomized block design , and compared the growth , fruiting and yield traits of castor .The results showed that the plant height increased with the increase in application amount of N , P2O5, KCl, and the plants in treatment 6 was the highest (301.67 cm). The castor in treatment 4 had the most single-plant capsule number (243.51), followed by that in treatment 3 (222.44).As for castor yield, the treatment 4 was the highest (3610.17 kg/hm2), followed by treatment 3 (3229.83 kg/hm2), while other treat-ments were under 3000 kg/hm2 .Therefore, the best fertilizing amount of castor in karst plateau mountainous area was N 172.5 kg/hm2 , P2 O5 45.0 kg/hm2 , KCl 180.0 kg/hm2 , and the best proportion of N , P2 O5 and KCl was 3.83∶1∶4.关键词
