香蕉茎秆有机肥对大白菜生长的影响

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。

Effect of banana stalk organic fertilizer to the growth of Chinese cabbage

In order to solve the problem of waste disposal after banana’s harvest, we used banana stalk to produce banana stalk organic fertilizer, through a plot experiment, we compared the growth influence of Chinese cabbage by normal organic fertilizer(Wanlvbao) and banana stalk organic fertilizer as base fertilizer usage, and evaluated its economic benefits. The results showed that: organic fertilizer took little effect on water content and nutrient content for Chinese cabbage, but took significantly effect on plant height and its leaf width, using organic fertilizer increased 22.50%-43.10% production of Chinese cabbage. On the condition of 6750 kg/hm2 normal organic fertilizer application, Chinese cabbage got the highest yield, which reached 30135 kg/hm2, next was 6750 kg/hm2 stalk organic manure fertilizer. For farmer conventional fertilization level (4500 kg/hm2), application of stalk organic fertilizer increased more than 3.50% to normal organic fertilizer, income increased 1800 yuan/hm2. As a kind of banana waste cycling products, cost for banana stalk organic fertilizer was low, and took good effects, in some case, it can be used instead of normal organic fertilizer.
