摘要
给出了用于度量水稻群体植伤的一组指标:植伤持续期、植伤强度和相对植伤势。分析了栽插密度、施用N素对盐粳187群体植伤的影响,结果表明,栽插密度对盐粳187群体植伤影响不显著,而施用N素则对群体植伤有显著影响。
A series of indexes for measuring tra nsplanting injury in rice populatio n(TIRP)were gived in this paper as follows:D uration of transplanting injury(DTI ),intensity of transplanting injury(ITI )and relative potential of transplan ting injury(RPTI ).Effects of planting density(PD)and applying nitrogen(AN)on TIRP of Yanjing 187were analysed,the results were that the effect of PD on TIRP of Yanjing 187was no significance and t he effect of AN on TIRP was significan ce.
