水稻不同基因型耐低磷分类.

Аccording to total P absorption per plant，grain weight and relative value of root volume in low P stress，the rice germplasm could be divided into 5 genotypes： I root extend adaption，II low concentration adaption，III waste， IV high P utilization efficiency，V passiveness adaption. VI high P utilization efficiency should be chosen when screening tolerant genotypes in low phosphorus because it could pro duce more biomass per unit P. 7 varieties with high P utilization efficiency were achieved，which were Niandali，Shuangchengnuo，Youmangxiaohongbandao，Maguzi，Laoyehuzi，Chengdejinzu，Nuozi.
