Natural organic fertilizers help to enhance soil health. Organic fertilizer is an environmentally friendly substitute, which can replace chemical fertilizer. As we all know, chemical fertilizer will consume soil microorganisms and make them immerse in groundwater, which will cause great "disaster" to lakes, rivers and marine life.
The main advantage of using organic fertilizer is that you will continue to cultivate in the next few years instead of consuming soil. By improving soil fertility and stimulating plant growth in a sustainable and environmentally friendly way, organic fertilizers will increase nutrients in the soil for plants to absorb. These nutrients are also used by many microorganisms living in healthy and productive soil, which in turn are beneficial to plant growth and improve plant immunity and tolerance to high temperature and drought conditions.
It is very difficult to grow vegetables, fruit trees or traditional Chinese medicine in hard and hardened soil or loose sandy soil (except for a few crops, such as Polygonatum sibiricum).
If organic fertilizer is mixed into the field, it will become food for microorganisms, which is conducive to the reproduction of microorganisms. Bacteria, fungi, various insects, earthworms and other creatures of different sizes began to move.
At this time, through the mucus secreted by microorganisms, the ionic structure becomes a small ball in the microscopic soil. This kind of soil becomes granular structure, which is very suitable for crop growth.
Because there is a gap between the glutinous rice balls and jiaozi, it can make the ventilation and drainage good. At the same time, jiaozi can also store water with good water retention.
There are many microorganisms in this soil, and there is a balance between them. Therefore, there will be no proliferation of malignant microorganisms, just like the human intestine, beneficial microorganisms and harmful microorganisms reach a balance. At the same time, the damage of crops mixed with organic fertilizer will increase the risk of pests and diseases.
How to use it? Apply base fertilizer (base fertilizer)
Base fertilizer, commonly known as base fertilizer, is a fertilizer applied before sowing or transplanting. When ploughing, organic fertilizer is applied evenly, and chemical fertilizer is turned into the soil with ploughing. This method is simple and feasible, and can achieve the purpose of improving soil. However, when it is evenly applied to the soil, it cannot be utilized by the root system. Therefore, the low utilization rate of fertilizer will inevitably lead to repeated waste and bring certain economic losses, and secondly, it will easily cause soil obstacles. Therefore, this method is more suitable for planting high-density crops.
Topdressing application
There are two methods of topdressing organic fertilizer: deep application in soil and topdressing outside roots. When soil is applied deeply, organic fertilizer is generally applied near the dense layer of roots, and then covered with soil to avoid nutrient volatilization loss. Topdressing outside the root is to mix compost with water 0/0 times of/kloc-evenly, stand and take its supernatant, and spray fertilizer solution on crop leaves with the help of sprayer for absorption by the leaves.
Used as seed fertilizer
There are many ways to use seed fertilizer, such as seed dressing, seed soaking, strip application, hole application and so on. Seed dressing is a method of dissolving or diluting organic fertilizer with a small amount of water, spraying it on the surface of seeds, stirring while spraying it, so that the fertilizer solution can evenly stick to the surface of seeds, and sowing after drying in the shade. Seed soaking is to dissolve or dilute the fertilizer solution into a solution with a certain concentration. According to the ratio of liquid seeds 1: 10, put the seeds into the solution and soak them 12~24h, so that the fertilizer solution can penetrate into the seed coat with water, and sow them immediately after drying in the shade. After ditching or digging a pit, apply the fertilizer into the furrow hole of 3-5 cm in the plough layer, and then sow near the fertilizer belt, keeping the distance between the seeds and the fertilizer above 3 cm. As a seed fertilizer, nutrients should be released quickly, and neither acid nor alkali can be used. The fertilizer itself has no toxic effect on seed germination. Organic fertilizer that is fully decomposed after composting is a good seed fertilizer.
Used as fertilizer for seedlings
Fully decomposed organic fertilizer, with uniform distribution and comprehensive nutrients, is an ideal fertilizer for seedling raising. Generally, a certain amount of peat, slungshot or perlite is added to 10% fermented organic fertilizer, which is mixed with soil evenly and used as seedling substrate.
Full-layer fertilization and centralized fertilization of organic fertilizer
Full-layer application is to spread organic fertilizer all over the surface and apply it to the whole soil layer through cultivated land. This fertilization method can be applied in the case of more organic fertilizer (4000 ~ 6000 kg per mu) or higher crop density. Centralized application in soil is to apply compost near the roots of crops by ditching. This fertilization method is worth using when the amount of chemical fertilizer is small (per mu 1500~3000kg) and the soil fertility is low.
