Scientific application of organic fertilizer Before planting, vegetable farmers should pay attention to increase the amount of organic fertilizer, deep application of organic fertilizer. Deep application of organic fertilizer can increase the content of organic matter in soil, promote the formation of soil aggregate structure, and increase the permeability of soil. In addition, vegetable farmers should also pay attention to increase the amount of biological fertilizer. Biological bacterial fertilizer can increase the amount of beneficial microorganisms in the soil and inhibit the occurrence of soil-borne diseases.
Reducing the amount of fertilizers used to grow crops before planting in greenhouses often involves the use of more organic fertilizers, and the amount of fertilizer used in later stages is greater. In this case, the use of chemical fertilizers or no chemical fertilizers should be reduced when the greenhouses are planted. Under high temperature, the solubility of chemical fertilizers in soil is high, and the salt content in the soil is more. Excessive application of chemical fertilizers is not conducive to the growth of roots.
Watering should be reasonably watered only to promote the deep rooting of vegetable roots and the formation of strong trees, which will benefit the high yield of vegetables. In general, one month after the vegetable is planted, the first three waters must be poured. Some vegetable farmers in the planting of vegetables, in order to promote the slow seedlings, blindly watering, watering no less than seven or eight times in a month. Watering is too busy, the soil is too wet, the roots are difficult to lower, vegetables are prone to leggy, disease resistance is poor, and fruit set rate is low. On the contrary, some vegetable farmers do not dare to water after vegetables are planted in order to prevent vegetables from prospering, and they will also affect the growth of vegetables.
Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
