Organic fertilizer can increase soil organic matter content in orchard and improve soil structure. Therefore, the application of organic fertilizer is one of the most important material inputs for the cultivation of orchards, and is also an important technical measure. Choosing the right organic fertilizer is an important condition to ensure the good growth of fruit trees and improve the quality of the fruit. So there are so many types of organic fertilizers, which ones are more suitable for orchards?
Traditional organic fertilizer
The application of traditional organic fertilizers has been around for a long time, and it is still the main practice of applying base fertilizers in most orchards in autumn and winter. In use, there are useful manure, chicken manure, cow dung, pig manure, sheep manure and other livestock manure and human excrement.
Sheep manure is a natural green fertilizer, which contains 4% to 27% of organic matter. It is more than other livestock manure. Nitrogen, phosphorus and potassium are rich in nutrients, fine in manure and rich in fertilizer. It is a hot fertilizer.
Chicken manure is rich in nutrients, especially in chicken manure, and the organic matter content is 25.5%. It can be a better green organic fertilizer through proper processing and utilization.
Pig manure contains 15% organic matter, the total nutrient content is not high, carbon and nitrogen are relatively small (14:1), and it is generally easy to be decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops.
The organic matter content of cow dung is 14.5%, the air-dried sample contains 43.6% of crude fiber, and the three elements of nitrogen, phosphorus and potassium are close to 1%.
Due to the large amount of traditional organic fertilizer per acre, deep digging and deep burial are required during application, and the labor intensity is large, which seriously affects the fruit fertilizer and the enthusiasm of soil organic matter. Coupled with the increasing aging of orchard production staff, the application of traditional organic fertilizer has been greatly challenged, affecting the sustainable production of orchards.
2. Straw returning and planting green manure
The traditional colony orchard operation rules generally require the excavation of a depth of 80 cm each of the planting ditch, filling the corn or wheat straw in the ditch, but in the large-scale realization of the machine to catch the machine, the straw returned to the field today, the above operation has changed It is not easy to achieve.
Grass production is the preferred ground management system for advanced countries and regions in Japan, Europe and the United States. The coverage of grass in Japanese orchards is over 90%, and the coverage of grass in orchards in Europe and the United States is also above 70%.
However, the grass-making system is rarely used in the production of orchards in China. Many orchards are mainly based on clearing and chemical fertilizers. When weeding work costs are low, and the efficiency is low, some orchards use herbicides, but the production is harmless and the use is not good. Will cause phytotoxicity.
Planting green manure in the orchard can not only increase soil organic matter content in orchard, reduce soil water evaporation, regulate soil temperature, improve soil physical and chemical properties, improve nutrient utilization, but also improve fruit tree growth, improve orchard yield and quality, and greatly reduce labor management intensity. Increase the economic benefits of the orchard.
3. Commercial organic fertilizer
The use of livestock and poultry manure, animal and plant residues and other organic-rich by-product resources as the main raw material, the fermented fermented fertilizer is called commercial organic fertilizer, which does not include green manure, farmyard manure and organic manure built by farmers themselves.
In today's large-scale development of the aquaculture industry, livestock manure as a raw material for commercial organic fertilizers has added more lime, clay and other materials to the environment during the management of the farm, which has reduced nutrients in disguise. Therefore, in order to meet the Ministry of Agriculture's ministerial standards, one is to add crop straw to co-fermentation, and the other is to directly add a certain proportion of humic acid raw materials, which will increase the production cost accordingly.
4. Bio-organic fertilizer
The bio-organic fertilizer has a complete range of nutrients, which can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply.
The beneficial microorganisms enter the soil and form a mutual symbiotic relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role of the group. The beneficial bacteria are produced during the growth and reproduction process. A large number of metabolites, which promote the decomposition and transformation of organic matter, can directly or indirectly provide crops with a variety of nutrients and stimulating substances to promote and regulate crop growth. Years of application can greatly alleviate continuous cropping obstacles and reduce environmental pollution. It is an environmentally friendly fertilizer.
Having said that, I believe that everyone has a certain understanding of organic fertilizer, right? In order to improve soil physical and chemical properties, improve fruit quality, produce high-quality fruit, save labor, and achieve labor-saving and labor-saving, it is recommended to use high-concentration bio-organic fertilizer with organic matter content of 40% or more as the base fertilizer for autumn and winter in the production of orchard. For years, the green manure is turned over, and the growing season is supplemented with an appropriate amount of chemical fertilizer, which can optimize the fertilizer type of the orchard and create a high-quality orchard.
