Effects of reducing chemical fertilizer application combined with organic fertilizer and microbial inoculant on yield and quality of post-wheat crop-ping baby cabbage
In order to establish a foundation for scientific fertilization in the post-wheat cultivation of Chinese cabbage(Brassica rapa var.chinensis),this experiment studied the effects of reducing chemical fertilizer in combination with organic fertilizer and microbial inoculant on the growth,yield,and quality of baby Chinese cabbage.The Chunyu Huang variety of baby Chinese cabbage served as the experimental material.Seven treatments were set up,including conventional fertilization,reducing chemical fertilizer mixed with increasing organic fertilizer,and microbial inoculant.The plant height,dry and flesh mass of aboveground and underground plant parts,flesh vegetable yield,net vegetable yield,netvege-table rate,as well as the concentration of vitamin C,total soluble sugar,and various mineral elements were measured.The results showed that reducing fertilizer application and increasing organic fertilizer could significantly increase plant height,dry and fresh mass of aboveground and underground parts,fresh vegetable yield and net vegetable yield of baby cabbage plants.Appropriate reduction of chemical fertilizer combined with organic fertilizer and microbial agent could promote the growth and high yield of baby cabbage,and significantly increase the content of vitamin C,soluble total sugar,soluble solid,as well as Ca,Fe and Zn mineral elements in baby cabbage,which improved its quality and nutritional value.The quality and yield of baby cabbage were improved by chemical fertilizer reduction combined with organic fertilizer and microbial microbial agent,among which JF4 treatment(chemical fertilizer reduction by 40％+organic fertilizer increase by 7500 kg·hm-2+microbial microbial agent 75 kg·hm-2)had the best effect,which could be used as an optimal fertilization scheme for multiple planting baby cabbage after wheat in this region.
