Brief introduction of Sanan compound fertilizer:
The proportion of nutrients is even, and nitrogen, phosphorus and potassium in "Sanan" account for 65,438+08% respectively. It is a general long-acting compound fertilizer with wide application range, especially suitable as base fertilizer, with long-lasting fertilizer effect, high utilization rate and few side effects, which is conducive to balancing soil nutrients and improving soil fertility.
It contains a variety of trace elements. In addition to nitrogen, phosphorus and potassium, "Sanan" also contains a variety of trace elements, which is conducive to promoting crop root growth, enhancing photosynthesis and improving crop stress resistance (drought resistance, waterlogging resistance, disease resistance, lodging resistance, cold resistance, freezing resistance, etc.). ) and significantly increase production.
The effect of increasing production is remarkable. After the application of "San 'an" to crops, the individual development is good, the population structure is reasonable, the early growth is not vigorous, the middle growth is stable and does not lodging, and the late growth is vigorous and does not premature aging. Generally, the yield can be increased by 20% ~ 30%.
Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties, which plays a very important role in balancing fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops.
The total content of compound fertilizer is generally high, and there are many kinds of nutrient elements. One-time application of compound fertilizer can supply at least two main nutrients to crops at the same time.
