| Abstract: | Sushu 9 has more roots,grows faster and roots enlarge earlier than Xushu 18(CK) after planting.Sushu 9 has higher rate of net assimilation.During the 70 days after planting,the dry matter accumulation of Sushu 9 is faster than that of Xushu 18,but it is not obvious at the late stage of growth.When N,P and K are used in combination,the yield of root and vine will be enhanced by N increasing.[HJ5:1] |
