Effects of Different Fertilizer Ratios on Greenhouse Cabbage Production
In order to explore the effects of different fertilizer ratios on the yield and quality of greenhouse cabbage,the fertilization experiment was carried out with Xiasheng No.1 as the experimental material.The results showed that the application of formula fertilizer,slow-release fertilizer and organic fertilizer instead of chemical fertilizer reduced the purity of chemical fertilizer by 22.1%,18.3%and 2.3%,the growth of cabbage was good,and the yield was higher than that of conventional fertilization.Although the cost of fertilizer input increased,the effect of increasing yield was significant,and the economic benefits of each treatment was better than that of conventional fertilization.Applying 300 kg of commercial organic fertilizer,30 kg of nitrate-N fertilizer(22-9-9)and 20 kg of urea per 667 m2 could not only reduce the input of chemical fertilizer and production cost,but also increase the crop yield and improve the planting income.
