氮磷钾配施对大蒜生长发育的影响
The influence of nitrogen,phosphorus and potassium fertilizer application on the growth and develop-ment of garlic
摘要
Abstract
Under the condition of the field test we have studied the effect of the ratio of N,P and K fertilizer on the de-velopment of garlic,including plant altitude,leaf-length,leaf-width,leaves number,nitrate nitrogen,content of as-corbic acid,content of chlorophyll,yield and economic benefit.The result showed that,more nitrogen,phosphorus and potassium may promote the plant high,N25 5 P90 K1 20 proportion was the best.Nitrate nitrogen increased with the N fertilizer,combined application of P,K fertilizer or phosphate diamine instead of superphosphate,nitrate nitrogen de-creased,and the treatment of N25 5 P90(磷铵)K240 was the lowest.More nitrogen and potassium may increase the content of chlorophyll,and N25 5 P90 K1 20 proportion was the best;N,P fertilizer application amount was too high,it would lead to the decline of the content of Vc,the treatment of N1 50 P45 K1 20 was the highest.With N fertilizer increased,the econom-ic benefit decreased.With the increase of P fertilizer,the yield of garlic was decreased.The yield of garlic was in-creased significantly under the combination of N25 5 and P90..Application of ammonium phosphate was better than super-phosphate.Provided fertilization with N 255 kg·hm-2 、P2 O5 45 kg·hm-2 、K2 O 120 kg·hm-2 ,the yield was the high-est.It is suggested that the garlic fertilization should control the amount of N and P fertilizer,and K application could improve the quality and the yield of garlic.关键词
