Effects of chemical fertilizer reduction and different amounts of compost on yield and quality of mini Chinese cabbage
In order to screen out the best fertilization treatment suitable for the growth of mini Chinese cabbage,no fertil-ization(NF)was used as the control,the local chemical fertilizer application amount(C)and the local chemical fertilizer application amount reduced by 30％(R)were the two chemical fertilizer application levels;0,400,600,800 kg·667 m-2 were four compost application levels.The two factors were combined into 8 treatments to explore the effects of fertiliza-tion treatment on growth,yield and quality of mini Chinese cabbage.Compared with the control,the plant width and ball height of the treatment with local chemical fertilizer reduction of 30％+600 kg·667 m-2 compost(R6)increased by 33.11％and 26.23％respectively,which were higher than those of conventional fertilization and chemical fertilizers.Oth-er treatments that reduced fertilizer use;R6 increased both dry and fresh mass compared with other treatments;the biologi-cal yield and economic yield of R6 increased by 52.23％and 120.21％,respectively;and the R6 treatment increased the vi-tamin C,soluble sugar,soluble protein and amino acid contents of mini Chinese cabbage and reduced nitrate content sig-nificantly.The principal component analysis results showed that the R6 treatment ranked the highest.In summary,30％re-duction of local chemical fertilizer plus 600 kg·667 m-2 compost treatment can significantly promote the growth of mini Chinese cabbage,increase yield,and improve quality.This fertilization method can provide scientific fertilization basis for the high-yield and high-quality production of local mini Chinese cabbage.
