The "Three Musketeers of Fertilizers" perfectly complement each other, help the vegetable harvest!

For vegetables to have a high yield, any link such as variety selection, seedling quality, and field management must be taken seriously. Among them, scientific fertilization is the most important thing. Vegetable yields are generally high, and reasonable fertilization should be given more attention.

At present, the main fertilizers used in vegetable production are the "three swordsmen", namely organic fertilizers, chemical fertilizers and biological bacterial fertilizers. Among them, organic fertilizers have the longest history and the oldest qualifications. The application history of chemical fertilizers in our country is less than half a century, while biological bacterial fertilizer is a high-profile new force in the fertilizer family. The capabilities of the "three fertilizers" are different. To ensure a good harvest and increase benefits, it is necessary to "combine the three fertilizers into one" "Only by complementing the shortcomings can we escort the vegetable harvest.

1. Organic fertilizer: "Decathlon", but it is easy to lose the chain at critical moments

Organic fertilizer mainly comes from plant residues and animal excrement. Its outstanding and irreplaceable advantage is that it has the most comprehensive nutritional content. It has all kinds of 16 kinds of essential nutrients necessary for vegetable growth. It is omnipotent, which avoids the short board on the yield bucket due to the lack of certain elements; the colloid formed after the decomposition of organic fertilizer can well improve the soil structure and improve soil cultivation performance. The function is the existence of high weight in the fertilizer family.

The weakness of organic fertilizers is that the level of fertility is limited. It cannot support the appetite for high-yield cultivation of vegetables by itself. Moreover, the nutrients in organic fertilizers must be released after being decomposed by microorganisms. The fertilizer supply is relatively slow. In the peak period, it will be unable to meet the fertility demand in a timely manner and lose the chain; another is the imbalance of organic fertilizer nutrients, with more nitrogen content but insufficient potassium content.

2. Fertilizer: a heroic vanguard, but lacks skills

Common chemical fertilizers are basically nitrogen, phosphorus, and potassium. The appearance of chemical fertilizers has shocked the production level of the entire agriculture, and is a dazzling milestone in the history of human agricultural civilization. Chemical fertilizers are highly soluble, and their ability to supply fertilizers in a timely manner is outstanding. During the peak production period typical of melons and solanaceous vegetables, chemical fertilizers are the most heroic vanguard to support sustained high production.

However, the shortcomings of chemical fertilizers are also obvious. First of all, the nutrient content is single. If it is used to meet the other ten kinds of trace elements necessary for crop growth, it will be exhausted. Another shortcoming of chemical fertilizers is that long-term large-scale application will increase soil salinization, affect root growth, and cause soil compaction. These will make the soil less arable and more difficult to increase production and income.

3. Biological fertilizer: powerful, but easily overlooked

As a "beautiful boy" that has attracted much attention on the entire fertilizer street, biological bacterial fertilizer is a very special existence, because it is not responsible for the specific business of supplying nutrients for vegetable growth. It is a low-key role that does not show up, but it is "but does good Don't ask about the future", the pure fat of being good at making wedding clothes for others.

The main endowment of biological bacterial fertilizer is that it can rescue nutrients that are absorbed and fixed by soil colloids but cannot be absorbed and utilized by roots, and change from an invalid state to an effective state. It can not only delay the salinization of the soil caused by excessive fertilization, but also can Reduce the amount of fertilizer to save costs. At the same time, microorganisms can produce metabolites that stimulate root growth and improve absorption capacity during the metabolic process.

However, the biggest shortcoming of biological bacterial fertilizer is that it cannot provide nutrients for vegetable growth like organic fertilizers and chemical fertilizers.

Summary: From the above analysis, it is not difficult to see that the three fertilizer swordsmen have different talents, but they all have shortcomings, but the three can achieve perfect complementarity.

How can the "Three Musketeers of Fertilizer" be more effective?

1. The issue of application time

Organic fertilizers are slow in fertilizer efficiency, so they should be used from the stage of soil preparation, that is, before sowing or planting vegetable seedlings, and should be applied at one time, so that the microorganisms in the soil can have relatively sufficient decomposition time. Provide a comprehensive nutrient guarantee during the growth process, but note that the organic fertilizer must be fully fermented and decomposed, otherwise this "all-around player" may release "poisonous gases" such as ammonia gas and hydrogen sulfide, which in turn will damage the vegetable seedlings.

Chemical fertilizers are very soluble. If they cannot be absorbed and utilized in time, they will infiltrate into the depths that the roots cannot touch with the water. Therefore, the chemical fertilizers used as base fertilizers can be applied 5-7 days before planting or sowing. Do topdressing when the peak period of yield accumulation comes.

In order for the biological fertilizer to play a role, it must rely on the strength of a huge group. Only by applying the microbial bacteria in the soil, the effect is relatively limited. The bacterial fertilizer is applied together with the organic fertilizer, and the organic fertilizer can just provide certain nutrients for the reproduction of microorganisms.

2. The issue of fertilization methods

From the perspective of nutrient content, the nitrogen content in organic fertilizers is relatively high. Therefore, for plots with a large amount of organic fertilizers, the amount of nitrogen fertilizers such as urea in the base fertilizer should be appropriately reduced. About 20% is enough, and the effect of topdressing in time with the growth of vegetables will be higher. The amount of organic fertilizer is relatively large, and it shoulders the mission of improving soil tillability, so the fertilizer should be fully spread and evenly mixed with the soil.

After the phosphate fertilizer enters the soil, the effective utilization rate is relatively poor. The more efficient application method is to apply enough base fertilizer at one time, but it is not suitable to spread it evenly before rotary tillage, which is more likely to be absorbed by the soil colloid. , Concentrated furrow application between cultivation rows. The utilization rate of potassium fertilizer is high, and the amount of potassium fertilizer should be increased after the flowering and fruiting period, and the amount of nitrogen fertilizer should be appropriately reduced.

In addition to applying the bacterial fertilizer in the base fertilizer, it can also be applied in the planting hole, or in the furrow between the rows, so that in the area where the root community is concentrated, the effect of dissolving phosphorus and potassium will be better.

To sum up, the three kinds of fertilizers can guarantee a good harvest if they are applied in the correct way.
