What are the organic foliar fertilizers? What are the commonly used organic fertilizers?

Foliar fertilizer can be divided into nutrient foliar fertilizer, regulating foliar fertilizer, biological foliar fertilizer, compound foliar fertilizer, etc., like nutrient foliar fertilizer has a high content of nitrogen, phosphorus, potassium and trace elements, which is suitable for the supplement of various nutrients in the later stage of crop growth, and there are other types of foliar fertilizer that are not supplemented.

There are four main categories, the first is a nutrient-type foliar fertilizer, which has a greater effect on mature plants or crops; The second is a regulated foliar fertilizer, which can make plants grow and develop better; The third type is a bio-based foliar fertilizer, which can make plants grow healthier and prevent pests. The fourth type of compound foliar fertilizer has a relatively comprehensive effect.

Vegetative foliar fertilizer, regulated foliar fertilizer, biological foliar fertilizer, compound foliar fertilizer. There are many kinds of compound foliar fertilizers, and there are various forms of compound and mixed fertilizers, which are basically the scientific combination of the above various foliar fertilizers.

1) Manure and compost.

It is rich in organic matter, has the effect of improving the physical properties of the soil, and is a complete fertilizer containing nitrogen (N), phosphorus (P) and potassium (K), which is mainly used as the base fertilizer for flowers in the open field.

2) Cow dung. It is a delay-acting fertilizer, the fertilizer effect is long-lasting, and it is mixed in the soil or used as top dressing with its leaching solution after it is fully decomposed.

3) Chicken manure. Completely fattened. High heat during fermentation, apply after sufficient decomposition, and do not touch the roots of the flowers directly. It can be fermented with 10 times water, and diluted 10 to 20 times when used to do top dressing.

4) Meal cakes.

It mainly contains nitrogen (N), but also phosphorus (P). It is mainly used as top dressing, but it can also be used as base fertilizer. Add 10 times water to ferment, and dilute 10 times when used to do top dressing.

5) Bone meal. Delay-acting fertilizer. It is suitable for use in high-temperature places such as greenhouses. It can be used as basal fertilizer, or it can be spread on the soil surface and mixed with topsoil as top dressing. It is better to mix with other fertilizers for fermentation. It can improve the quality of flowers and has a significant effect on enhancing the strength of flower stems.

6) Rice bran. It mainly contains phosphorus, promotes the decomposition of other fertilizers, and has a long fertilizer effect. It can be used as base fertilizer.

7) Grass ash.

It mainly contains potassium and has high fertilizer efficiency, but it is easy to make the soil compact. Species with weak roots and sowing are better used.

8) Horseshoe slices, horns.

Chop and mix with soil, make base fertilizer after rotting, and make base fertilizer for potted plants. It can also be soaked in water and diluted to make top dressing.

Organic fertilizer, commonly known as farmhouse fertilizer, refers to a slow-release fertilizer with a large amount of biomass, animal and plant residues, excrement and biological waste. Organic fertilizer not only contains macronutrients and trace elements required by plants, but also organic fertilizer is rich in organic nutrients. The main role of organic fertilizer in agricultural production is manifested in the following aspects:

1. Soil improvement and fertility improvement After organic fertilizer is applied to the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the ability of soil maintenance and fertilizer and buffer, and create good soil conditions for crop growth.

Two: increase yield, improve quality, organic fertilizer is rich in organic matter and various nutrients, providing nutrients for agricultural crops. After the organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote crop growth and improve agricultural products.

Three: improve fertilizer utilization. Organic fertilizer contains a variety of nutrients but has a relatively low content and slow release, while chemical fertilizer has a high unit nutrient content, few components and is released quickly.

The two are applied rationally and complement each other to decompose organic matter. The organic acids produced also promote the dissolution of mineral nutrients in the soil and fertilizers. Chemical fertilizer and organic fertilizer promote each other, which is conducive to crop absorption and improves fertilizer utilization efficiency.
