What fertilizer should be put into the Lycium barbarum tree in crops?

Compared with pure chemical fertilizer, compound fertilizer can increase income and improve efficiency, which has been recognized by farmers. However, it is still difficult for farmers to control how to choose high-quality compound fertilizer in order to achieve the goal of low consumption and high efficiency. In addition, there are many kinds of compound fertilizers on the market, and there are fresh names and flowers on the packaging.

Joe's words added to the difficulty of identification. Therefore, farmers need to know the common sense of choosing compound fertilizer. ?

Emperor Yifei reminds you:

First, controlling the basic process of compound fertilizer production has a guiding role in selecting compound fertilizer. Compound fertilizer can be easily divided into potassium chloride type, potassium sulfate type and potassium nitrate type according to the composition process. Among them, potassium chloride is the most widely used conventional compound fertilizer with relatively low cost; Potassium sulfate is a compound fertilizer for chlorine-free or chlorine-sensitive crops with strong specificity and moderate cost. Potassium nitrate is a kind of advanced compound fertilizer developed in recent years, which has no side effects on soil. Such as rice, potassium chloride compound fertilizer, tea, citrus,

Potassium sulfate compound fertilizer can be used for vegetables. Potassium nitrate compound fertilizer can be used for citrus and tobacco. ?

Di Yifei believes that,

Second, it is very necessary to master the grading standards of high, medium and low concentrations of compound fertilizers when purchasing compound fertilizers. The internal quality of compound fertilizer is determined by the production process, and another important index is the content of effective nutrients. Available nutrients can only be labeled with N+P2O5+K2O, and other nutrients are not labeled (GB15063-94-94 standard). It is not standard for some enterprises to label elements such as S into total nutrients, which misleads farmers. Effective nutrients ≥ 40% are high-concentration compound fertilizers, effective nutrients 30-40% are medium-concentration and effective nutrients 25-30% are low-concentration. The minimum nutrient standard of ternary compound fertilizer is ≥ 25%, 20-25% can only produce binary compound fertilizer, and less than 20% is a product that is not allowed to be produced by the state. Therefore, knowing this.

This concept is of positive significance to the purchase of compound fertilizer. You can get a glimpse of the grade of compound fertilizer just by looking at the packaging. ?

The first fertilizer, the best fertilizer

Third, the purchase of compound fertilizer can not only be judged by appearance, particle size, color and solubility, but also by brand effect. Brand is the product of market competition, and high-quality products have recognized market effects. At present, some small domestic enterprises keep witnessing the appearance of counterfeit brand-name products or inferior imported products in order to cater to the illegal entreaties of some dealers, which seriously damages the legitimate interests of farmers and should be vigilant. For example, sulfur-containing compound fertilizer is often sold as potassium sulfate compound fertilizer in the market to deceive farmers.

In fact, in a real sense, most compound fertilizers contain sulfur. Fourthly, the choice of compound fertilizer varies with time, place and use. Acidic soil, soil with low organic matter content, should choose alkaline compound fertilizer or organic compound fertilizer, alkaline soil should choose acidic compound fertilizer, such as humic acid ternary compound fertilizer, phosphorus-rich or potassium-rich soil can choose directional binary compound fertilizer. Potassium nitrate compound fertilizer can be used in dry season. Ammonium-nitrogen compound fertilizer can be applied in plum season or rainy season, coarse-grained compound fertilizer can be used as base fertilizer to prolong fertilizer efficiency, and small-grained compound fertilizer can be used as topdressing to accelerate fertilization.

Effective.

In short, the choice or purchase of compound fertilizer should aim at economy, safety, high efficiency and quality improvement to achieve the best value. ?
