Preface for using organic fertilizer in apple orchards：
Why do apple orchards pay attention to the application of organic fertilizer produced by organic fertilizer production line? What are the benefits of organic fertilizer for apple trees? What is the effect of organic fertilizer produced by organic fertilizer production line on apple tree growth? Today, GATE organic fertilzier production line manufacture will give a brief introduction.
1. The organic fertilizer produced by the organic fertilizer production line not only contains all kinds of essential nutrients needed for apple growth and development, although the content is low compared with chemical fertilizers, but the varieties are all, not only contain a lot of nutrient elements nitrogen and phosphorus needed for fruit tree growth. Potassium, calcium, magnesium, sulfur, etc., also contain trace elements such as zinc, iron, B, manganese, etc. required for vegetative growth of fruit trees. It plays a very important role in coordinating the supply of various nutrient elements. At the same time, the organic fertilizer produced by the organic fertilizer production line is relatively slow in the supply of nutrients, generally not easy to appear fat damage phenomenon and long supply time and balanced growth is not easy to appear fattening phenomenon.
2. organic fertilizer produced by the organic fertilizer production line can significantly improve the physical properties of the soil.
Tests have shown that the organic fertilizer is mixed with the soil. The organic matter produced by the organic fertilizer produced by the organic fertilizer production line and the solid particles in the soil cross each other to form a soil structure with a good effect. The formation of the agglomerate structure can reduce the adhesion between the soil particles by 2-6 times and the adhesion force by 60%, which not only makes the orchard's farming operation more labor-saving, but also can greatly reduce the growth resistance of the root system and contribute to the extension of the root system. And the absorption and utilization of nutrients.
3. organic fertilizer produced by the organic fertilizer production line can improve soil buffer capacity of nutrients, reduce fertilizer damage, improve fertilizer efficiency.
Organic substances in organic fertilizers can produce large amounts of organic acids and humic acids during decomposition. These acidic substances not only promote the release of essential nutrients such as phosphorus, iron and zinc contained in the soil, but also combine with the applied urea, ammonium hydrogencarbonate, etc., and adsorb it to the surface of these acidic substances. The concentration of ammonium ions in the soil solution can prevent a large amount of ammonia nitrogen poisoning which is more likely to occur in the application of ammonium nitrogen fertilizer; at the same time, it reduces the volatilization and leaching loss of nitrogen fertilizer. The adsorbed fixed nitrogen fertilizer can be continuously released during the growth process of the apple tree, and is uniformly supplied to the fruit trees for absorption and utilization; not only improves the fertilizer efficiency, but also coordinates the nutrient supply of the soil.
4. The dark matter contained in the organic fertilizer produced by the organic fertilizer production line can increase the absorption of solar energy by the soil, and is conducive to improving the ground temperature in early spring.
The roots of apple trees can withstand a certain low temperature. Generally, the soil temperature begins to absorb nutrients at around 5 °C, but the rate and capacity of nutrient absorption increase gradually with the increase of ground temperature. When the temperature reaches 30 °C, there is a maximum value. It began to decline gradually. When the upper part of the early spring fruit tree has not been grown in a large amount, the sunlight can be irradiated to the surface in a large amount. The soil produced by the organic fertilizer produced by the organic fertilizer production line is darker in color, more solar energy is absorbed, and the ground temperature rises faster, which can promote the root system. Early activities, more absorption and accumulation of some nutrients for the use of the tree after germination, to promote the growth and development of apple trees.
