The low utilization rate of fertilizers is mainly due to improper fertilization methods.
Measure
According to the production target, we should do a good job of balanced fertilization. Within a certain range of fertilization, crop yield is positively correlated with fertilization. If the total amount of fertilization or the amount of single fertilization is too much, the ecological balance will be lost due to the nutrient environment, but it will be reduced. Therefore, it cannot be said that the more fertilizer is applied, the higher the yield will be. It has been determined that for every 100 kg of rice produced, 1.85 kg of nitrogen, 0.85 kg of phosphorus pentoxide and 2.1 kg of potassium oxide are required to be absorbed from the soil. For every 100 kg of lint produced, it needs to absorb 12.0 kg of nitrogen, 4.0 kg of phosphorus pentoxide and 12.0 kg of potassium oxide. Of course, when determining the amount of fertilizer, we must also consider factors such as climate, soil, and fertility.
Adhere to deep fertilization, to achieve water and fertilizer. In production, it is necessary to adhere to the deep application of chemical fertilizers in order to protect the fertilizer with soil cover and reduce volatilization and loss. When the sensation is insufficient, it is necessary to properly irrigate the water and adjust the water to adjust the fertilizer.
Mix organic fertilizer to enhance adsorption capacity. After mixing chemical fertilizers with organic fertilizers, the available nutrients can be adsorbed or combined by organic fertilizers, and then gradually released, which not only prolongs the time of fertilizer supply, but also reduces the unnecessary consumption of nutrients.
Improve fertilizer preparations and regulate peak fertilizer supply. The first is to make a single-type fertilizer into a broad-spectrum compound fertilizer; the second is to make special fertilizer according to the fertilizer characteristics of the crop; the third is to use the modified means to make the quick-release fertilizer into slow-release fertilizer; Fertilizer and bio-organic fertilizer make up the advantage of compensating granular fertilizer, early or delayed application time, so that the peak of fertilizer demand and the peak of fertilizer supply are connected to each other, and the fertilizer effect is fully exerted.
