中小型西瓜不同生育期对氮磷钾的吸收分配规律研究
Study on the absorption and distribution of nitrogen,phosphorus and potassium of middle and small size watermelon in different growth stages
摘要
Abstract
The absorption and distribution characteristics of main mineral nutrients of nitrogen, phosphorus,potassium of watermelon were studied under the condition of spring sowing facilities cultivation using ‘Zaojia 8424’and ‘Zaochunhongyu’watermelon varieties as materials.The results showed that the absorption and distribution rates of nitrogen,phosphorus,potassium are different in different growth stages of watermelon,distribution of N,P,K is mainly used for the development of leaf before fruiting,the second is for the growth of the stem,and turns to fruit development gradually after fruit setting.Among the absorption amount of N,P,K of watermelon,K was the most,the second was N,the least was P.The total amount of N,P,K absorbed by ‘Zaojia 8424’in mature stage were 24.21 g/plant,and the N∶P2 O5∶K2 O ratio was 1∶0.26∶1 .84;The total amount of N,P,K absorbed by‘Zaochunhongyu’in mature stage were 25.04 g/plant,and the N∶P2 O5∶K2 O ratio was 1∶0.29∶1 .62.关键词
