How to apply calcium magnesium phosphate fertilizer? Calcium magnesium phosphate fertilizer is a kind of multi-element fertilizer which mainly contains phosphorus and contains calcium, magnesium, silicon and other components. Calcium magnesium phosphate fertilizer is insoluble in water, non-toxic, non-corrosive, not easy to absorb moisture, not easy to caking, so it is a chemical alkaline fertilizer. It is widely used in all kinds of crops and phosphorus-deficient acidic soil. The application methods are as follows: first, it is most suitable for deep application of base fertilizer. After calcium magnesium phosphate fertilizer is applied to the soil, phosphorus can only be dissolved by weak acid and can only be used by crops after a certain transformation process, so the fertilizer effect is slow, so it belongs to slow-acting fertilizer. In general, combined with deep ploughing, fertilizer is evenly applied to the soil and mixed with the soil layer, so as to facilitate the dissolution of soil acidity and the absorption of crops. Second, mixed with more than 10 times of high-quality organic fertilizer for more than one month, the retting fertilizer can be used as base fertilizer, seed fertilizer, or dipped in seedling roots. 3. Matters needing attention in the application of calcium magnesium phosphate fertilizer: 1. The effect of calcium magnesium phosphate fertilizer combined with common calcium and nitrogen fertilizer is better, but it can not be mixed with them. two。 Calcium magnesium phosphate fertilizer usually can not be mixed with acid fertilizer, otherwise it will reduce the effect of fertilizer. 3. The amount of calcium magnesium phosphate fertilizer should be appropriate, generally, the amount of calcium magnesium phosphate fertilizer per mu should be controlled at 15murmur20kg. Excessive application of calcium magnesium phosphate fertilizer will not only not increase the fertilizer utilization efficiency, but also decrease. Usually, when magnesium phosphate fertilizer is applied per mu at the rate of 35ml / mu, 40kg / mu can be applied every other year. 4. Calcium magnesium phosphate fertilizer is most suitable for crops with strong ability to absorb citrus soluble phosphorus, such as rape, radish, legume crops and melons.
