Effect of Banana Stalk Organic Fertilizer on the Growth of Chinese Cabbage.

In order to solve the problem of waste disposal after banana harvest, we use banana stalk to produce banana stalk organic fertilizer, through a plot experiment. We compare the influence of normal organic fertilizer (Wanlubao) and banana stalk organic fertilizer as base fertilizers on Chinese cabbage growth, and evaluate the economic benefits of banana stalk organic fertilizer. The results show that organic fertilizer has little effect on water content and nutrient content of Chinese cabbage, but has significant effect on plant height and leaf width. Using organic fertilizer can increase the production of Chinese cabbage by 22.50%-43.10%. With 6750 kg/ha normal organic fertilizer, Chinese cabbage gets the highest yield, which reaches 30135 kg/ha, followed by the treatment of 6750 kg/ha stalk organic fertilizer. At farmers' conventional fertilization level (4500 kg/ha), stalk organic fertilizer can increase the yield by more than 3.50% in comparison with the normal organic fertilizer, and the economic benefit increases by 1800 yuan/ha. As a kind of banana waste cycling product, banana stalk organic fertilizer is of low cost and good effect, and can be used instead of normal organic fertilizer. [ABSTRACT FROM AUTHOR]
