| Research on field effect and manufacture technology of "PJF"active fluid fertilizer Wu Junsheng ABSTRACT "PJF"active nutritional fluid fertilizer was a new type fertilizer made by Institute of soil and fertilizer, Shanxi academy of agricultural sciences. It was suitable for spraying on leaves of plant and on soil. Compared with other types of fluid fertilizer, its nutrient content is one of the highest ones. It was composed of 16% macro-element, 4% microelement, and fluid acid or plant growth regulator. There were not any heavy metals in this fertilizer, so it was safe to crop and environment. There was organic buffering regent, so it could be safely mixed with any pesticide, bactericide and herbicide. After diluted by tap water, no precipitation happened. The field experiments suggested that "PJF"active nutritional fluid fertilizer obviously increased production of corn by 6.9-31.0%, and winter wheat by 7.1- 38.0%, and apple by 11.2-35.0%, and vegetable by 6.3-32.9%. Furthermore, this fertilizer could increase plant-suffering ability when it was encountered drought, hail and other weather disaster. Applying "PJF"active nutritional fluid fertilizer could markedly increase plant yield and farmer's income, and also improve crop quality. |
