Description

Preparation method of special organic fertilizer for pepper
Technical Field
The invention relates to the technical field of fertilizer preparation, in particular to a preparation method of a special organic fertilizer for pepper.
Background
The zanthoxylum bungeanum also called green zanthoxylum bungeanum, green pepper, pricklyash peel, red pepper and red pepper is an economic plant of the genus zanthoxylum of the family rutaceae, and the fruit of the zanthoxylum bungeanum is a traditional seasoning material and a traditional Chinese medicinal material, so the zanthoxylum bungeanum has higher economic value. The pepper is deciduous shrub or small arbor, 3-7 m high, developed root system, drought and barren resistance, wide distribution range, and remarkable ecological benefit. The pepper is a dual-purpose tree species integrating ecological benefit and economic value, and the pepper has become the first-choice economic tree species of masses in mountain areas.
The special organic fertilizer is provided based on the problems of different growth habits of various crops, differences of different nutritional requirements, characteristics of different soils and the like. The core of the production of the special organic fertilizer is the problem of the formula. In the crop planting process, the soil quality can be reduced by using the fertilizer for a long time, the granular structure of the soil is difficult to form under the condition of lacking organic matters, the adhesion among soil particles is weakened, the water retention capacity of the soil is gradually reduced, and even the better fertilizer can not release energy under the proper environmental condition when the soil can not keep sufficient water. And the water and soil are lost, and the fertilizer is easy to cause pollution. The organic fertilizer can improve the soil and fertilize the soil, and after the organic fertilizer is applied to the soil, the physical and chemical conditions and the biological characteristics of the soil can be effectively improved, the soil is cured, and the water retention capacity, the fertilizer supply capacity and the buffer capacity of the soil are enhanced. On the other hand, the organic fertilizer can improve the yield and the quality of crops, contains rich organic matters and comprehensive nutrient elements, and provides green and environment-friendly nutrients for the crops.
The growth period of the pepper is very long, the pepper tree is in the young stage before the seeds germinate and emerge to blossom and fruit, and the young stage is generally 2-3 years; the period from the beginning of flowering to the beginning of mass fruiting is the initial stage of fruiting, a small amount of flowers and fruits can be obtained after 3 years of planting of the pepper trees, and the flowers and the fruits are increased after 4-5 years; the full bearing period is that the pepper trees generally enter the full bearing period from 10 years to before aging, the yield is obviously increased, the full bearing period generally lasts for 10-15 years, and the long period can reach 20 years. The pricklyash trees are photic, drought-resistant and barren, so that large areas of pricklyash trees in China are planted in terraced fields, mountain areas, barren mountains and the like. However, like other fruit trees, the pepper trees need to absorb major elements such as nitrogen, phosphorus and potassium and trace elements such as boron, zinc and copper from soil, and in order to ensure high and stable yield of the pepper trees in successive years, the pepper trees need to be fertilized in time to supplement nutrients so as to meet the requirements of growth and fruiting of the pepper trees. The method has two fertilization stages of base fertilizer and top dressing, and can meet the growth requirement of the pepper tree only by ensuring sufficient fertilizer quantity. Due to the long growth period, the base fertilizer is required to be applied before the pepper tree is planted, and after the fruiting period, the base fertilizer is also required to be applied from the harvest of the pepper every year to the germination of the pepper tree in spring. The base fertilizer is mainly organic fertilizer and is mixed with phosphate fertilizer. The application of the base fertilizer in autumn can increase the propagation of soil microorganisms, and is beneficial to converting the soil microorganisms into inorganic salt so as to be quickly absorbed and utilized by the root system of the pepper tree. Meanwhile, the growth soil environment of the pepper is generally arid and barren, so that quick-acting fertilizer and slow-acting fertilizer are needed to be applied in production, and organic fertilizer, particularly biological organic fertilizer, is a good choice of slow-acting fertilizer and plays a very important role in maintaining the good ecological environment of the pepper. At present, for the convenience of greedy maps, many farmers mostly select single chemical fertilizers or water-soluble fertilizers for applying fertilizers in pepper production; unreasonable fertilization has great influence on the yield and the quality of the pepper, and the problems of late fruiting, early fallen leaves, low yield and easy premature senility of young trees in production are prominent.
The growth period of the pepper is long, the growth environment of the pepper easily causes the loss of the nutrient components of the fertilizer, and the development of the high-quality special fertilizer rich in various nutrient elements for pepper production is an important way for solving the problems at present. In view of the above, we propose a preparation method of organic fertilizer special for pepper to solve the above problems.
