Which fertilizers are allowed to produce green grapes?

1 Allowable application of base fertilizer

1) Farmyard manure. There are mainly compost, manure, manure, uncontaminated mud, cake fertilizer and so on. It should be fully fermented and fermented when applied. It also includes green manure and crop straw fertilizer.

2) Commercial organic fertilizer. A fertilizer produced by processing animal and plant residues, excreta, and biological waste as raw materials.

3) Humic acid fertilizer. Fertilizer produced from peat, lignite and weathered coal.

4) Microbial fertilizers. The active microbial preparation produced by a specific microbial strain is non-toxic and harmless and does not pollute the environment. It can improve the plant's nutrition or produce hormones through microbial activities and promote plant growth. At present, microbial fertilizers are divided into five categories: 1 microbial compound fertilizer. The three types of beneficial bacteria symbiotic systems, such as nitrogen-fixing bacteria, activated potassium bacteria, and activated phosphorus bacteria, are not antagonistic. It can improve the soil nutrient supply level and is an ideal source of fertilizer for producing pollution-free green fruits. 2 nitrogen-fixing bacteria fertilizer. It can fix nitrogen in the soil and in the rhizosphere of the grapes to provide nitrogen nutrition for the grapes. 3 nodules fertilizer. It can increase the supply of nitrogen in the rhizosphere soil. 4 phosphorus bacterial fertilizer. It can convert the insoluble phosphorus in the soil into available available phosphorus and improve the phosphorus nutrition in the soil. 5 phosphate bacteria fertilizer. Potassium-containing phosphates and apatites such as mica and feldspar in the soil can be decomposed to release potassium nutrition.

5) Organic compound fertilizer. Mixed or combined preparations of organic and inorganic substances. For example, after the harmless treatment of livestock and poultry manure, a suitable amount of fertilizer made of trace elements such as zinc, manganese and boron is added.

6) Inorganic (mineral) fertilizer. Mineral potassium fertilizer and potassium sulfate, mineral phosphorus powder, calcined phosphate rock salt, powdered sulfur fertilizer (limited to the appropriate amount in alkaline soil), limestone (limited to acidic soil application).

2 Applicable top dressing

1) Grape leaf top dressing must not contain chemically synthesized growth regulators. The foliar fertilizer that is allowed to be used is a trace element fertilizer, and a fertilizer formulated with trace elements such as copper, iron, manganese, zinc, boron, and beneficial elements.

2) Plant growth auxiliary fertilizers, such as the use of natural organic extracts or inoculating beneficial bacteria fermentation broth, and then add some humic acid, alginic acid, amino acids, vitamins and other fertilizers.

3 Other fertilizers allowed to be applied

Foods that do not contain synthetic additives, organic by-products of textile industrial products; fertilizers that contain preservative-free fish residue, beef wool waste, bone meal, amino acid residues, and livestock processing waste.
