Bio-organic compound fertilizers have been widely used in agricultural production in China in recent years. This kind of organic fertilizers combined with inorganic fertilizers, accompanied by a variety of micro-organisms or high-energy compounds, is very popular among farmers. The benefits are also obvious: First, it can improve the physical and chemical properties of the soil, improve the water retention and fertilizer retention performance, and continue the cotton production stamina; the second is to significantly inhibit cotton blight and enhance the resistance to stress, especially in cotton fields with severe blight, the performance is more significant. The third is to reduce the pollution of the farmland environment; the fourth is to promote high yield and stable yield of cotton and improve fiber quality.
Although bio-organic compound fertilizer has many significant advantages, its share in the agricultural capital market is still relatively limited. There are also great differences in the application of localities. Some areas have large application areas, and some are still in their infancy. Not yet exploited. The reason is that some places reflect that the sales price is too high, and the farmers are unbearable; some reflect that the fertilizer effect starts slowly and the crop dominant effect is weak; some think that the fertilizer production process is different, and the rough craftsmen are unwilling to agree. Others say that individual product fertilizers are not stable enough.
Why do these problems occur when fertilizers that are supposed to be optimistic? According to our many years of investigation and analysis, the first is that the price of raw materials for the production of organic compound fertilizer is too high, and the intermediate links in sales are excessive, which increases the production and marketing costs. Second, the fertilizer formula emphasizes the content of organic matter and ignores In the fertilization process, only the bio-organic compound fertilizer was applied alone, and the quick-acting fertilizer was not applied. Fourth, the soil moisture was insufficient when fertilizing, or the local temperature was too low, and it was difficult to release the fertilizer effect. In this regard, in order to give full play to the role of bio-organic compound fertilizers, policy support, increased production and savings, correct guidance, and scientific use should be adopted to accelerate the application.
First, optimize production costs. First, policy support, governments at all levels should subsidize 100 yuan to 200 yuan per ton of bio-organic compound fertilizer, as in grain production; second, use organic raw materials on site, not suitable for long-distance transportation, increase costs; third, reduce sales links, Try to do a good job in terminal sales; Fourth, enterprises organize technology to the countryside, do a good job in after-sales service, so that fertilizers can fully exert fertilizer efficiency.
Secondly, it is necessary to apply at a suitable temperature. Regardless of the soil applied, there must be sufficient sensation to promote rapid differentiation and transformation. The temperature is in the range of 10 °C ~ 30 °C, and when the temperature is lower than 10 °C or higher than 30 °C, the conversion and absorption of fertilizer will cause obstacles.
Third, it must be properly applied. First, in order to make the fertilizer play a long-lasting and quick-acting effect, all the fields where bio-organic compound fertilizer is applied should be applied with 15~25 kg of inorganic compound fertilizer or 30~40 kg of ammonium bicarbonate per mu, and then according to the soil of cotton field. In case of potassium deficiency, supplement a certain amount of potassium fertilizer, can not replace potassium fertilizer with bio-organic compound fertilizer; second, apply base fertilizer, 50 kg per mu is appropriate; third, when soil moisture is insufficient, one must be deep application, and the second is to be in water source. Good place to fight drought after the application.
