化肥减施对大蒜经济性状及烤烟-大蒜轮作土壤养分的影响
Effects of chemical fertilizer reduction on the economic traits of garlic and soil nutrients in flue-cured tobacco-garlic rotation
摘要
Abstract
In order to identify the optimal fertilization amount for garlic(Allium sativum L.)that does not affect garlic yield,has a small impact on tobacco quality,and is environmentally friendly,a field plot experiment was conducted to study the effects of different fertilization rates on the economic traits of garlic and soil nutrients in flue-cured tobacco-garlic rotation,with a reduction of 20%,40%and 60%on the basis of garlic farmers'habitual fertilization rates.The results showed that the economic traits of garlic bolt were the best when the fertilizer application rate was reduced by 60%,the economic traits of bulb were the best when the fertilizer applica-tion rate was reduced by 40%,and the total output value of garlic was the best when the fertilizer application rate was reduced by 40%.Considering the risk of non-point source pollution of nitrogen and phosphorus,the loss amount and loss rate of nitrogen and phospho-rus were significantly reduced under the treatment of 60%reduction of fertilizer application(P<0.05),but the yield and total output value of garlic bulbs were not significantly reduced under this treatment(P<0.05),which was the optimal garlic fertilization treatment.Because the contradiction in nitrogen fertilizer management under garlic and flue-cured tobacco rotation could not be resolved,garlic was not suitable as a pre-crop for flue-cured tobacco.关键词
