Abstract:

This experiment was conducted to understand the effects of different types of fertilizers, fertilizer ratios, and amount on the agronomic traits and yield of vegetable soybeans, further screening of suitable fertilizer types and optimization of fertilizer structure. The results showed that treatment 1 performed the best in terms of the quantity and quality of different types of bean kernels; From the three indicators of total pod number, total mass, and average pod mass, treatment 1 performed the best; There is no significant correlation between 100 grain weight and the number of branches, plant height and the number of branches, and 100 grain weight and the yield; Treatment 4, with a base fertilizer of 300 kg·hm^-2 (nitrogen phosphorus potassium ratio of N 20%, P₂O₅ 15%, K₂O 10%) and topdressing of 525 kg·hm^-2 (N 14%, P₂O₅ 4%, K₂O 22%), can achieve maximum yield; Treatment 5, Hanfeng (with a nitrogen phosphorus potassium ratio of N 22%, P₂O₅ 10%, K₂O 16%) can achieve maximum plant height by applying 600 kg·hm^-2 at once; Treatment 6, Haolegeng (nitrogen phosphorus potassium ratio of N 13%, P₂O₅ 6%, K₂O 8%) can achieve a maximum 100 grain weight by applying 1 020 kg·hm^-2 at once. The amount and ratio of fertilizers and fertilizers from different manufacturers will have a significant impact on the yield of vegetable soybean Zhexian 9.
