Reasons for the low content of organic matter in orchard soil

There are many reasons that affect the change of soil organic matter content. Organic fertilizer equipment manufacturers think that it mainly includes the quantity and structure of fertilizer input, planting mode, soil type, agricultural product market and agricultural technology.
1. The fertilization structure is unreasonable. The main reason for the low soil organic matter is that a large amount of fertilizer and organic fertilizer are not enough. The application of organic fertilizer is more labor-consuming, and the whole process requires the material to be mixed by the compost turning machine for composting. The fertilizer production line processes compost, and the price of organic fertilizer is higher, while the fertilizer is cheap and favored, and the organic fertilizer is ignored. The main reasons for the change of orchard soil quality are insufficient input of organic nutrients, excessive application of nitrogen and phosphorus, relatively insufficient input of potassium, excessive and frequent use of copper containing fungicides. The use of this kind of chemical fertilizer year after year increased the total nitrogen of orchard soil, but decreased the C / N ratio, resulting in soil hardening, acid-base imbalance and fertility decline. With the increase of planting years, the soil properties of orchard degenerated obviously.

2. The source of organic fertilizer is seriously insufficient. Although the number of commercial bio organic fertilizer plants has increased rapidly in recent years, these organic fertilizer production equipment can not meet the demand, and there are still problems such as price and quality. Local organic fertilizer producers in most countries are far from meeting the actual needs. At the same time, the price of commercial organic fertilizer is on the high side and people are unwilling to use it, which limits the large-scale application of commercial organic fertilizer.
3. The cultivation mode of orchard grass was not effectively applied. Although the cultivation mode of orchard grass is an effective way to improve the ecological conditions of orchard, improve the soil fertility, increase the organic matter of soil, and produce high-quality fruits, so as to make the orchard healthy and healthy. But on the one hand, the traditional idea is that the orchard should be cleared up and weeded. It is one-sided to link orchard grass with fruit trees competing for fertilizer and water. It is not willing to grow grass, and it is not fully aware of the serious problems of soil degradation and fruit quality degradation caused by large-scale application of chemical fertilizer. On the other hand, the lack of scientific management technology and Research on the grass orchard, the inadequate management of the grass orchard, and the lack of management and utilization of the planting grass lead to the idleness of the grass in the orchard, which does not play a key role in improving the fertility of the orchard, and further aggravates the wrong idea that the grass and fruit trees compete for fertilizer and water. Therefore, in the aspects of management and utilization of orchard forage, such as determination of mowing time, mechanization of mowing, prevention and control of diseases and pests before and after mowing, protection of natural enemies, scientific utilization of mowed forage, regeneration and rejuvenation of forage, we should further strengthen research and improve technology.
4. Biodegradation aggravates the poor soil. Sufficient light, proper temperature and proper precipitation are favorable for the growth and development of fruit trees and the activities of aerobic microorganisms in the soil. The activities of these microorganisms aggravate the degradation process of organic matter in the soil and make it transform into carbon dioxide to escape from the soil, resulting in lower organic matter. If not supplemented in time, it will aggravate the impoverishment of the soil. The soil needs high quality fertilizer processed by organic fertilizer granulator.

Process of fermenting livestock manure into organic fertilizer

The raw materials of organic fermentation compost include straw, animal manure, domestic sludge, processing organic waste, garden pruning waste, biomass waste, etc. Composting refers to the process of harmless and stable solid organic waste through the function of microorganism in fertilizer production line under certain water, C / N ratio, ventilation and other artificial control conditions. Compost is a kind of production method of organic fertilizer and a biological treatment method of solid waste.
Technological process of organic fertilizer composting


The production process of organic fertilizer compost includes: raw material storage and pretreatment, compost inoculation, fermentation, aging fermentation, compost quality inspection, finished product packaging or processing of organic fertilizer production equipment.

  1.  In the raw material storage area, dry materials with low moisture content should be stored in the rain to keep low moisture content;
  2.  Wet materials with high moisture content should not be stored for a long time. They should be treated in time to reduce the generation of odor and leachate as much as possible and prevent secondary environmental pollution.
  3.  There should be a special raw material storage area for raw material storage. It is better to set up a raw material storage workshop in which different raw material characteristics are classified for storage;
  4.  The water content, particle size, C / N and pH value of organic fertilizer shall be adjusted in the pretreatment process.

The process of livestock manure fermentation into organic fertilizer

  1.  Stacking on the ground, using the ground umper, or putting materials in the fermentation tank, using the trough dumper
  2.  Evenly sprinkle the fungicide, turn over the pile and ferment to reach the temperature rise, stink, decay, and kill the miscellaneous bacteria and grass seeds
  3.  Fermentation 7-12 days, according to the temperature of different places, the number of times of turning pile is different
  4.  Complete fermentation and maturity, out of the tank (directly collected by forklift on the ground)
  5.  Use the grading screen for coarse and fine screening (the screened powder fertilizer can be sold directly)
  6.  Smash the screened block with a grinder and return it to the grading screen
  7.  Mix the required trace elements in a blender
  8.  Granulating with fertilizer granulator.Fertilizer granulator can choose disc granulator, double roller granulator, organic fertilizer granulator, drum granulator, flat die granulator, and ring die granulator.
  9.  Feed to dryer and cooler
  10.  Automatic packaging machine packaging sales
