【摘要】 为了解决香蕉收获后废弃物的处理难题,利用香蕉茎杆制备成品有机肥,通过小区试验比较普通商品有机肥和香蕉茎秆有机肥做底肥施用对大白菜生长的影响,并对其经济效益进行评价。结果表明,施用有机肥对大白菜含水量和养分含量影响不大,但对大白菜株高和叶宽促进效果明显,施用有机肥使大白菜增产22.50%~43.10%,在万绿宝有机肥施量为6750 kg/hm2的条件下,大白菜产量最高,达30135 kg/hm2,6750 kg/hm2茎秆有机肥次之,在农民习惯施肥水平下(4500 kg/hm2),施用茎秆有机肥可比万绿宝有机肥增产3.50%,收益增加1800元/hm2。香蕉茎秆有机肥作为一种废弃物的再利用产品,其成本较低,应用效果好,在一定程度上可以代替商品有机肥使用。更多还原

【Abstract】 In order to solve the problem of waste disposal after banana harvest, we used banana stalk toproduce banana stalk organic fertilizer, through a plot experiment, we compared the influence of normalorganic fertilizer(Wanlvbao) and banana stalk organic fertilizer as base fertilizers on Chinese cabbage growth,and evaluated the economic benefits of banana stalk organic fertilizer. The results showed that: organicfertilizer had little effect on water content and nutrient content of Chinese cabbage, but had significant effect onplant height and leaf width. Using organic fertilizer could increase the production of Chinese cabbage by22.50%-43.10%. With 6750 kg/hm2 normal organic fertilizer, Chinese cabbage got the highest yield, whichreached 30135 kg/hm2, next was the treatment of 6750 kg/hm2 stalk organic fertilizer. At farmers’ conventionalfertilization level(4500 kg/hm2), stalk organic fertilizer could increase the yield by more than 3.50% incomparing with the normal organic fertilizer, the economic benefit increased 1800 yuan/hm2. As a kind ofbanana waste cycling products, banana stalk organic fertilizer was of low cost and good effect, and could beused instead of normal organic fertilizer.更多还原
