| 摘 要： | 研究表明，西瓜苗期对氮、磷、钾的吸收很少。随着植株的生长逐渐增多，抽蔓到一棚瓜成熟期间对氮的吸收有明显的线性关系，回归方程为ｙ＝０．１４１９ｘ－５．３８７８，ｒ＝０．９９７１＊＊。座果后对磷的吸收逐渐增多；开花结果后对钾的吸收逐渐增多。西瓜植株对、氮、磷、钾的分配在结果前主要用于叶的发育和建成，其次是茎、根的生长；座果后，逐渐转向果实的发育

| Abstract: | During 1987-1989 field experiments showed that watermelon absorbed little N,P,K during the seedling stage but it gradually took more when the vining stage.A significant linear relation was found on the N absorption from vining to the first harvest,with the regression equation being:y=0.1419 x-5.3878,r=0.9971 ** .The plant gradually absorbed more P after setting and took even more K during flowering and fruiting stages.N P and K primarily contributed to the development and establishment of leaves and they also supported the growth of stems and roots before fruiting.After setting,N,P,K were gradually concentrated in the fruits. |
