Features: 1, new fertilizer: Acidic compound fertilizer phosphate is a new high-efficiency fertilizer developed for soil in alkaline areas, and it is an upgraded product of traditional diammonium phosphate, which is made from the addition of pyridine phosphate, nitrogen phosphorus activator, sulfur and other active substances. With loose soil, promote absorption, phosphorus efficiency, long-lasting nitrogen, living nutrition characteristics. 2, three major effects: 1, reduce the pH of alkaline soil, continue to improve the soil. 2, improve the utilization rate of nitrogen 50%. 3, improve the utilization rate of phosphorus 50%. 3, the mechanism of product action: The pH value of the surrounding soil can be significantly reduced by the ratio of 1:5 and pH 3.0, and the pH value of the soil around the soil of the acidic compound fertilizer of phosphoric acid is reduced, which reduces the volatilization of ammonium nitrogen, thus improving the utilization rate of nitrogen fertilizer; The acidification membrane technology and phosphorus activation agent of phosphorus-phosphate acidic compound fertilizer products can ensure that phosphorus in their products is not fixed, and can activate the fixed phosphorus elements in the soil, reduce the fixed soil of phosphoric acid root, extend the "freshness period" of effective phosphorus, and increase the continuous supply capacity of phosphorus. How to use: (1) Trial crops: all kinds of fields and cash crops.
(2) Fertilization period: before the vegetable sedgout, after the fruit is harvested, the base fertilizer before the planting of the field crop.
(3) sea fertilizer mode: dense planting crops such as wheat, millet, spinach, etc., can be removed after ploughing or trench ingestion, wide-line planting crops such as corn, potatoes, peanuts, cotton, fruit shelter, etc., can be ditched,
to ensure better fertilizer.
(4) Fertilizer dosage: base fertilizer dosage 15 to 25 kg / mu
(5) It is advisable to use with other fertilizers.
Note:
(1) When concentrating fertilization, pay attention to the isolation of fat planting.
2 This product has strong acidity, can not be mixed with alkaline fertilizer
(3) Suitable for alkaline soil filling, acidic soil careful use
(4) The specific dosage can be determined according to the characteristics of crop fertility, soil fertility, fertilization methods and other compound fertilizer stoma that needs to be matched.
