The annual spring plowing will soon begin. Farmers are all preparing seeds, fertilizers and pesticides, of which fertilizers are the most used. The mixed use of organic fertilizer, compound fertilizer and biological organic fertilizer can not only ensure the nutrients needed for plant growth and development, but also kill insects and cure diseases, improve nutrient utilization, and achieve a win-win goal.

Organic fertilizer: It is a kind of fertilizer that contains a lot of organic matter and a variety of quick-acting nutrients. It is the most nutrient-rich fertilizer. It can develop a variety of nutrients for crop growth, and at the same time, it can supplement the organic matter that is seriously lacking in the soil and improve the soil. surroundings. However, due to the specialization of farming, most families no longer farm, and organic fertilizers are becoming less and less. If you want to apply organic fertilizers, you can only buy organic fertilizer products processed by manufacturers on the market.

Compound fertilizer: It is currently the largest amount of chemical fertilizer. This fertilizer has high nutrient content, good solubility, and can provide a variety of nutrients for crop growth. Due to the increasing amount, the utilization rate is getting lower and lower, causing the volatilization and loss of a large amount of nutrients, the soil compaction is serious, and the pest damage is getting more and more serious.

Microbial fertilizer: it is a kind of fertilizer containing a large number of beneficial microorganisms, bacteria and fungi. These beneficial bacteria mainly include Bacillus subtilis, Bacillus licheniformis, Bacillus cereus and other beneficial bacteria. After this fertilizer is applied to the soil, Under temperature and humidity conditions, these microorganisms can use the organic matter in the soil to multiply at a speed 6-10 times faster than that of the pathogens, and quickly become the dominant bacteria in the soil. At the same time, these beneficial bacteria can also secrete bacteriolytic substances to inhibit and kill the soil. Propagation of other harmful germs to achieve the purpose of pest control. This kind of microbial fertilizer is gradually recognized by farmers' friends.

How to match it reasonably!

1. Pay attention to the application time. Organic fertilizer is slow and effective. It should be applied early. Generally, it is applied as a one-time base before sowing or planting. It is best to decompose before use. The effect of topdressing in the later period is not as obvious as that of base fertilizer.

Chemical fertilizers have quick results. When used as base fertilizer, they should be applied about a week in advance. When topdressing, they should be applied before the critical period of crop nutrition or the peak period of nutrient absorption to meet their needs.

Biological bacteria fertilizer can only play the role of bacteriostasis after being multiplied in the soil, so it must be applied early before planting to allow time for reproduction and growth. It can be applied to the soil together with organic fertilizer or before planting Or point application when planting.

2. Pay attention to the application method. The main function of organic fertilizer is to improve the soil and provide nutrients at the same time. It is generally applied to the soil as a base fertilizer. Therefore, it must be combined with deep plowing to completely mix the soil with the organic fertilizer to achieve the purpose of improving the soil. It can be used in conjunction with biological stimulants to better improve the soil environment, balance nutrients, and increase soil aggregate structure.

In the base fertilizer, because the nutrient in the organic fertilizer is mainly nitrogen, the nitrogen fertilizer matched with the organic fertilizer can be used less, and 30% can be used as the base fertilizer and 70% as the top dressing. Phosphate fertilizer and potash fertilizer can be applied as base fertilizer at one time. Phosphate fertilizer is not suitable for later application due to its poor mobility, so phosphate fertilizer should be applied to the soil as base fertilizer.

Topdressing chemical fertilizer is best to use fully soluble quick-acting fertilizer as the main fertilizer. After such fertilizer is decomposed, it can be quickly absorbed by vegetables and has little impact on the soil.

Biological bacterial fertilizer can be applied in the planting hole or along with organic fertilizer because of its low dosage. In the later stage, the same biological bacterial fertilizer can be applied multiple times to strengthen the bacterial flora and improve the ability of dissolving phosphorus and potassium and preventing diseases.

3. Pay attention to the amount of fertilizer used for different crops in different growth periods, and the amount of fertilizer required is different. Fertilization should be carried out according to the different required fertilizer ratios of crops. At the same time, attention should be paid to the overall consideration of the content of nutrient elements in the soil. It is best to conduct soil testing once, and follow the recommendations for soil testing and fertilization.
