| 摘 要： | 本文根据硅酸盐菌剂即生物钾肥具有分解和氧化土壤硅酸盐矿物，破坏矿物晶体构造，转化土壤中无效钾的机能，于１９９２～１９９４年进行了生物钾肥对冬小麦生长发育与产量效应的试验研究。探讨出以播前拌种返青沟施是促使小麦促根、增蘖、抗寒、抗干热风、增穗、增粒、增重，提高缺钾麦田再创高产的重要途径。

| Abstract: | The silicate bacterial agent called Biological potassium Furtilizer(B. P. F. )has the advantages of decomposing and oxidizing the ineffective minerals in soil into the effective ones by means of breaking up the mineral crystal structure. Therefore,the experiments of effects of B. P. F. on wheat growth and yield as well were carried out with the duration of 1992￣1994. The results showed that these practices seed dressing with B. P. F.before sowing and furrow application at the stage of turning green would give the wheat plant a better development in root system,more tillering,stronger resistance to both coldness and drought,and higher increase in ears and weight per kiloseed. So they are spoken of as the most important ways to reincrease in wheat yield in the fields in lack of potassium furtilizer. |
