Bio-organic compound fertilizers, which are combined with organic fertilizers and inorganic fertilizers, are accompanied by a variety of microorganisms or high-energy compounds. They are popular among farmers and have obvious effects. First, they can improve soil physical and chemical properties, enhance water retention and fertilizer retention. To improve the ability of continuous fertilizer supply; secondly, it can significantly inhibit the diseases of cotton, melon blight and rice sheath blight, and enhance the resistance to stress; third, it can improve the quality of crops, especially to improve watermelon, sugar cane, strawberry, etc. The sweetness of the fruit is very obvious; the fourth is to promote the increase of crop yield. Generally, the application of bio-organic compound fertilizer is about 10% higher than that of single-application fertilizer; the fifth is to reduce the pollution of the agricultural environment and produce a large amount of pollution-free food.
Although bio-organic compound fertilizers have many significant advantages, their share in the market is still relatively limited, and there are also large differences in the use of localities. The main 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 farmers who use plastic greenhouses to grow vegetables reflect the phenomenon of burning seedlings. Why are these problems occurring? First, the price of raw materials used for producing fertilizer is too high, and the intermediate links in sales are excessive, and the price is increased. Second, the single application of bio-organic compound fertilizer ignores the effect of other fertilizers, or the application rate is too low. Third, the soil when fertilizing Insufficient sensation, or the temperature was too low at the time; fourth, the amount of application was too large. In order to give full play to the fertilizer efficiency of bio-organic compound fertilizers, it is necessary to accelerate the promotion and application by means of increasing production, saving, correcting, and scientific use.
First, reduce production costs. First, the use of organic raw materials on the spot, not long-distance transportation, increase costs; Second, reduce the intermediate links in sales, production and sales close-up docking; Third, do a good job in after-sales service, organize technology to the countryside, so that fertilizers quickly play fertilizer.
Secondly, it is necessary to apply at a suitable temperature. Regardless of the soil applied, there must be sufficient sensation to promote rapid decomposition 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 35 °C, the conversion and absorption of fertilizer will cause obstacles.
Third, it must be properly applied. First, in order to make the fertilizer reflect the long-acting and quick-acting effect, all the fields where the bio-organic compound fertilizer is applied should be applied with about 30 kg of ammonium bicarbonate per mu, and then other nutrients should be applied according to the needs of different crops. Compound fertilizer replaces other fertilizers. The second is to apply base fertilizer, the amount per mu does not exceed 50 kg. Especially in plastic greenhouses, it is even more difficult to apply. Third, when the soil moisture is insufficient, it is necessary to promptly resist drought and control after application.
