不同有机肥施入量对有机蔬菜产量的影响研究

Effect of Different Amount of Organic Fertilizer in the Yield of Organic Vegetables

以青刀豆、西兰花、甘薯、胡萝卜和圆葱等主要有机蔬菜为试材,研究不同有机肥施入量对有机蔬菜产量的影响。结果表明:随着施入有机肥数量的增加,5种蔬菜的产量都呈递增的趋势,但施肥量增加到一定量后,有机蔬菜产量提高不明显,差异不显著;667m2地块中青刀豆的最佳施肥量为2000kg;西兰花和甘薯的最佳施肥量为2500kg;胡萝卜和圆葱的最佳施肥量为3000kg。

The effect of different amount of organic manure in the yield of green beans,broccoli,sweet potatoes,carrots and onions of was studied.The results showed that：the yields of five vegetables were all increased as the increasing of the amount of organic fertilizer.But statistical analysis showeed that after a certain amount of fertilizer to organic vegetable,the production increase was not obvious,the difference was not significant.The comprehensive analysis showed that the best amount of fertilizer for green beans was 2 000kg;the best amount of fertilizer for broccoli and sweet potatoes was 2 500kg;the best amount of fertilizer for carrot and onion was 3 000kg.
