贵州冬作马铃薯增施钾肥的效益分析
Benefit Analysis of Increasing Application Rate of Potassium Fertilizer in Production of Winter Potato in Guizhou
摘要
Abstract
In order to obtain detailed data to guide the rational application of fertilizers, we studied the effects of different fertil-izers, fertilizer combinations, and various fertilization modes on the yield, tradable potato rate and economic benefit of winter potato production in Guizhou.The results showed that:applying different kinds of fertilizers had obvious influences on the yield and trad-able potato rate of winter potato; fertilization mode had significant influence on the tradable potato rate.After applying K2 SO4 +( NH2 ) 2 CO+water or KCl+( NH2 ) 2 CO+water, better effects were acquired, and the output value, net income, and income-increasing (in comparison with the control) percentage of winter potato production were 48490.5 yuan/hm2, 21378.0 yuan/hm2, 120.2% or 45750.0 yuan/hm2, 18997.5 yuan/hm2, 95.7% respectively.Thus, K2SO4 +(NH2)2CO and KCl +(NH2)2CO could be properly popularized, utilized and further verified in the production of winter potato in Guizhou.关键词
