Abstract
Objective] To research the proper dosages of organic fertilizer and nitrogenous fertilizer to enhance the yield and economic benefits of Chinese cabbage.[ Method] Based on the same dosage of phosphate fertilizer and potash fertilizer , four dosages of organic fertilizers and ni-trogenous fertilizers were designed for single application and combined application.[Result] Yield of no fertilizer region was the lowest, which was only 11 075.0 kg/hm2 .Among the fertilizer application treatments, single organic fertilizer treatment had the lowest yield, which was only 12 937.5 kg/hm2;while treatments of 3 000.0 kg/hm2 commerical organic fertilizer,150.0 kg/hm2 urea, 300.0 kg/hm2 ordinary superphosphate and 375.0 kg/hm2 potasslium sucfate was the highest, which was 19 525.0 kg/hm2; and their economic benefits were the maximum, reaching 29 287.5 yuan/hm2.[Conclusion] Research showed that based on large-area cultivation of Chinese cabbage, we suggest to adopt the treatment of 3 000.0 kg/hm2 organic fertilizer, 150.0 kg/hm2 urea, 300.0 kg/hm2 ordinary superphosphate and 375.0 kg/hm2 potassium sulfate.This treatment could enhance the yield of Chinese cabbage , promote the mutual complementation between organic fertilizer and chemical fertilizer , and is helpful to the crop absorption.关键词
