摘要
为筛选出适于娃娃菜生长的最佳施肥方案,以不施肥(NF)为对照,以当地化肥施用量(C)和当地化肥施用量减量30％(R)为两种化肥施用水平;以0、400、600、800 kg·667 m-2 4种堆肥施用水平,两因素组合成8个处理,研究不同施肥处理对娃娃菜生长、产量及品质的影响.结果表明,与对照相比,当地化肥施用量减量30％+600 kg·667 m-2堆肥(R6)处理的株幅和球高分别显著增加33.11％和26.23％,高于常规施肥处理和其他化肥减施处理;R6与其他处理相比干鲜质量均增加;R6的生物产量和经济产量分别比NF显著提高52.23％和120.21％;且R6处理与NF相比,显著提高娃娃菜维生素C、可溶性糖、可溶性蛋白、氨基酸含量,显著降低硝酸盐含量.主成分分析结果表明,R6处理的排名最高.综上,当地化肥减量30％+600 kg·667 m-2堆肥处理可明显促进娃娃菜生长、提高产量、改善品质,该施肥方案可为当地娃娃菜高产优质生产提供参考.
Abstract
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.
