| 摘 要： | 以苎麻中苎一号为材料,以常规扦插苗为对照,利用打顶技术(扦插时打顶和插后一周打顶)对低位分枝扦插苗的营养特性进行研究。结果表明:低位分枝扦插苗对氮、磷、钾的积累总量及根、茎、叶中氮、磷、钾的积累量均高于常规扦插苗;低位分枝扦插苗与常规扦插苗根、茎、叶不同部位的氮、磷、钾含量的增长规律一致,氮含量的增长前期表现为叶>根>茎,后期表现为叶>茎>根;磷含量的增长前期表现为根>叶>茎,后期表现为叶>根>茎;钾含量的增长前期表现为根>茎>叶,后期表现为茎>根>叶。 |

| Abstract: | With ramie varieties of Zhongzhu No 1 as materials and regular cutting-seedling as control,adopting the new method of cultivation in the field,the nourishment characters of low-branch and regular method breeding were studied.The results showed that the total N,P,K and the N,P,K in the stem,root and leaf respectively was higher than the regular method for the low-branch new planted ramie,but it was opposite in reproductive organs.In the low-branch and the regular method new planted ramie,the distribution patterns of the content of N,P,K was the same:the N content distribution in the early stage was leaf>root>stem,in the later stage was leaf>stem>root;the P content distribution in the early stage was root>leaf>stem,in the later stage was leaf>root>stem;the K content distribution in the early stage was root>stem>leaf,in the later stage was stem>root>leaf. |
