摘要: 以鄂牧6号饲用苎麻(Boehmeria nivea L.)为试验材料,研究了苎麻叶片中5种矿质营养元素(N、P、K、Ca、Mg)6个收获时期的含量动态变化及相关性。结果表明,苎麻叶片中5种营养元素含量、吸收量及吸收速率都表现为N>Ca>K>Mg>P。N、P、K、Ca、Mg 5种营养元素含量变化规律不同,但5种元素的吸收量、吸收速率变化规律相同,都表现为先升高后下降。K与N、Mg含量间分别呈显著负相关和正相关(P<0.05), Ca与K、Mg含量间呈极显著正相关(P<0.01)。

Abstract: The dynamic changes and the relativity of five mineral nutrients (N, P, K, Ca and Mg) of feeding ramie Emu No.6 leaves were studied during six harvest periods. The results showed that the content, absorption amount and absorption rate of the five nutrients in the leaves were N> Ca> K> Mg> P. The contents of N、P、K、Ca and Mg were different at different harvest periods. The absorption amount and absorption rate of the five elements changed in the same way, and all of them increased first and then decreased. Elements K and N, K and Mg showed remarkable negative relativity and positive relativity(P<0.05), Ca and K, Ca and Mg showed extremely remarkable positive relativity(P<0.01).

Key words: ramie (Boehmeria nivea L.), nutrient elements, leaves, change
