Reasons for the low content of organic matter in orchard soil

2020/03/11
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 windrow turner 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 fertilizer manufacturing process 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 fertilizer granulator machine.
