At present, the application of chemical fertilizers is more and more, but the output has not seen much growth. The main reason is that the fertilization method is not appropriate, and the following measures should be taken for this purpose.
According to the production target, the balanced fertilization is within a certain range of fertilization, and the crop yield is positively related to the fertilization amount. 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 kg of nitrogen, 4 kg of phosphorus pentoxide and 12 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 the deep fertilization, to adhere to the deep application of chemical fertilizers in the production of water and fertilizer, in order to protect the fertilizer with soil cover, reduce evaporation and loss. When the sensation is insufficient, it is necessary to properly irrigate the water and adjust the water to adjust the fertilizer.
Mixing organic fertilizer to enhance adsorption capacity After mixing chemical fertilizer with organic fertilizer, the available nutrients can be adsorbed or combined by organic fertilizer, and then gradually released, which not only prolongs the time of fertilizer supply, but also reduces the unnecessary consumption of nutrients. .
Improve fertilizer preparations, regulate the peak of fertilizer supply. First, make a single-type fertilizer into a broad-spectrum compound fertilizer; second, make special fertilizer according to the fertilizer characteristics of crops; third, use modified means to make quick-release fertilizer. Slow-release fertilizer; Fourth, the granular fertilizer that makes the inorganic fertilizer and bio-organic fertilizer make up the advantage, early or delay the 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.
