摘要: <正>通过盆栽实验,研究了NH÷N与N03--N两种形态氮素不同配比对红松幼苗光合特性的影响及其生理机制。结果表明,与对照(cK)相比,氮素处理降低了膜透性,提高了净光合速率、气孔导度、RuBP羧化酶活性、糖含量、光系统电子传递活性等生理指标。不同氮素混合处理使红松幼苗各生理指标增加的效应大于纯NH+4-N和NO3-N处理效果。在混合处理中,以n(NH+4-N)/n(NO-3-N)(摩尔比)为1/32/2时的效果最显著,红松幼苗光合性能最佳。因此苗木施用氮肥时应考虑不同形态氮素的合理配比问题。

Abstract: The right-transposed, left-transposed and full-transposed matrices were introduced in the paper [1] and some properties of them were given. This paper also gave the definition of some concepts of O-orthogonal,R-orthogonal and L-orthogonal matrices and some necessary and sufficient conditions and some related conclusions of O-orthogonal, R-orthogonal and L-orthogonal matrices.
