Comparative Study on the Effects of Fertilizer Reduction with Efficiency Increase by Appling Different Rice-Specific New Type Fertilizers
摘要
Abstract
[Objective] To study the difference of fertilizer reduction, cost saving, efficiency and income increase of rice-specific new fertilizers type in rice production. [Method] The two-line hybrid rice Longliangyou 688 was used as material, and the treatment without fertilization was used as the control, the influence and difference of rice-special loss-control fertilizer, charcoal based long-term fertilizer, maintenance fertilizer, active synergistic fertilizer, active glycopeptide fertilizer and conventional compound fertilizer on rice growth, yield, fertilizer use efficiency and economic benefits were studied. [Result] The application of new fertilizers for rice promoted the prolongation of the peak tillering period, and increased the number of tillers and effective panicles. The new fertilizer treatments reduced N, P and K by 12.51％, 6.67％ and 6.67％ respectively, saved fertilizer cost by 184.65 kg/hm2, and reduced the cost of labor by 1 125元/hm2. Although slightly reduction of yield, the agronomic utilization efficiency, partial productivity and the net income were generally increased. Compared with the conventional fertilizer treatment, the effective panicle number increased by 14.76％, the total grain number per panicle increased slightly, and the yield increased by 4.8％, N agronomic use efficiency and N partial productivity increased by 29.3％ and 19.6％ respectively, P and K agronomic use efficiency increased by 21.4％, P and K partial productivity increased by 12.3％, and the net income increased by 2 573. 85 yuan/hm2 under active glycopeptide fertilizer treatment, which had the most effect of fertilizer reduction, cost saving, efficiency and income increase. [Conclusion] According to the effect of efficiency and income increase, the order of rice-specific new fertilizers type was active glycopeptide fertilizer＞ charcoal based long-term fertilizer＞ active synergistic fertilizer＞ loss-control fertilizer＞ maintenance fertilizer.关键词
