Bio-organic compound fertilizer can prevent shed vegetable fertilizer

One increase: increase the application of fully decomposed organic farmyard manure to improve soil fertility. In recent years, the promotion of refined organic fertilizers has overcome the shortcomings of farmyard manure and avoided the occurrence of fertilizer damage.

Second control: control the amount of fertilizer, suitable for the mid-range level. It should also be noted that the foliar fertilizer should be sprayed to the optimum concentration to achieve twice the result with half the effort. When the concentration is too high, it is sprayed at high temperature at noon, which is prone to fat damage.

Sanqin: Master the principle of a small amount of diligence, avoid excessive application of high-concentration fertilizer.

Four with: Formulation of fertilization. It is necessary to change the nitrogen fertilizer to reduce nitrogen, stabilize phosphorus, increase potassium, and apply organic fertilizer, NPK and trace element fertilizers.

Five-cover: Advocate full-scale deep application or ditch application of soil, it is not appropriate to spread on the soil surface. The point should be more than 10 cm from the roots of the crop.

Six washes: use June or August to wash the salt with precipitation or irrigation.

Seven changes: deep soil or 0-20 cm surface soil, or rotated greenhouses to reduce surface salt.

Eight pushes: We must vigorously promote bio-organic compound fertilizers. The biological fertilizer contains microbial activated bacteria, which is a "four-in-one" fertilizer composed of organic fertilizer, inorganic fertilizer, bacterial fertilizer and synergist. It realizes the scientific formula of various fertilizers, complementing each other's advantages, and achieving the balance of greenhouse vegetables. One of the best fertilizers for fertilization.
