植物钾素营养研究进展

将植物钾素营养研究进程分成三个阶段 ,从钾的生理作用研究 ,钾对农产品产量和品质的影响 ,逆境胁迫与钾素营养研究 ,生物钾肥的研究 ,耐低钾基因型的筛选等五个方面入手 ,对钾素研究作了比较详细的综述 ,并对近年来我国钾素研究取得的进展进行评述。认为生物钾肥的研制和耐低钾基因型的筛选是今后研究的重点 ,是解决我国钾源短缺的有效途径

Studying Proceeding of Plant Potassium Nutrient

The study of plant potassium nutrient is divided into three stages. Five aspect researches, e.g. the physiological function of potassium, the effect of potassium on the yield and quality of agricultural products, adverse circumstance force and potassium nutrient, bio potassium fertilizer and the choosing of genes which produce low content potassium are reviewed in detail. The study proceeding of potassium in our country in recently years is also discussed. Meanwhile the study way and focal point about potassium have been put forward. Studying and making bio potassium fertilizer and choosing the genes which produce low content potassium is to be the stress and the effective way to solve the short potassium resource in our country in the future.
