2种缓释肥对干制辣椒经济产出效益及肥料利用率的影响
Effects of Two Kinds of Slow-release Fertilizers on Economic Output and Fertilizer Utilization Efficiencies of Dried Peppers
摘要
Abstract
[Objective] The aim was to improve the dried pepper yield and output value, overcome the blindness and accuracy of fertilization, and increase the fertilizer utilization efficiency, so as to find out the suitable slow release fertilizer and balance application technique for the promotion of Yunnan dried pepper in the main producing areas. [Method] The field plot experiment was conducted to study the effects of two kinds of slow-release fertilizer and balance-recommended fertilization on the growth, output and fertilizer use efficiency of dried pepper. [ Resujl ] Both balance-recommended fertilization and two kinds of slow-release fertilizer were conducive to dried pepper growth and fertilizer uptake efficiency, thereby contributing to an increase in the dry matter accumulation and economic output efficiency of dried pepper fruit. Compared to conventional fertilization, the fertilizer utilization efficiency increased separately by 11.68% , 10. 64% and 8. 56% in the condition of balance-recommended fertilizer, slow release compound fertilizer and urea refined (slow release nitrogen fertilizer) , the pepper production increased by 20. 94% , 17. 50% , 14. 54% , and the net output value increased by 3 820, 3 656 and 3 146 yuan/hm2. The dried pepper production increased primarily through monoclonal fruiting number. [Conclusion] The fertilizer nitrogen inputs could be reduced to improve fertilizer uptake, thereby cutting down the waste of resources and reducing the environmental risks under slow release fertilizer and balance-recommended fertilization without reducing-the yield of dried peppers.关键词
