Fermentation process

The production process of Organic fertilizer is mainly to lower the moisture content than lower than60%Organic solid waste is mixed and uniformly mixed with auxiliary materials (plant straw, etc.), microbial fermented bacteria, etc., and continuously fermented through pool -type oxygen to make it fully rot, sterilize, deodorize, and remove water.Rotten material moisture content is general30-35%Within the range, it can be directly used to produce spherical organic Fertilizers after screening and magnetic selection, or after further drying the powder and organic production.

Granular process process

The process of Compound fertilizer can be divided into: raw materials, mixing raw materials, raw materials, granules, granular drying, granular cooling, granular grading, finished envelope, and final finished packaging.

1, Raw ingredients:

Hulmum, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (one ammonium phosphate, cyclistan, severe calcium, general calcium), potassium chloride (potassium sulfate) and other raw materials are equipped at a certain proportion (according to market demand and soil in various placesTest results).

2, Stir in raw materials:

Stir well raw materials to improve the uniform Fertilizer content of the overall Fertilizer particles.

3, Raw material granules:

Send the raw materials that are mixed evenly into the granulator (can be used to make granulation, or squeezed granules)Essence

4, Granules drying:

Send the granular particles into the dryer to dry the water contained in the particles to increase the strength of the particles and make it easy to save.

5, Granules cooling:

The temperature of the dry Fertilizer after drying is too high, and it is easy to make the mass. After cooling, it is easy to store and transport.

6, Granular grading:

The cooled particles are graded, and the unqualified particles are crushed and re -made of granules, and the qualified products are divided.

7The finished film film:

increase the qualified products to increase the brightness and roundness of the particles.

8, Finished packaging:

Put the wrapped particles in the finished product in the ventilated place.

benefit

Analysis of social benefits

How to make full use of the resources of organic waste is an important issue in my country to establish a resource -saving society, promote the circular economy and develop organic agriculture.my country is a large country with Fertilizer consumption. The production of chemical Fertilizers must consume a lot of non -renewable resources such as coal, electricity, and natural gas. The development of this project uses solid organic waste to produce ball -type particle organic Fertilizers to achieve the purpose of saving non -renewable resources and protecting the environment. The social benefits are huge, which is in line with my country's energy conservation and emission reduction industrial policies.

Ecological environmental benefits

Increasing the application of Organic fertilizer can effectively solve the pollution caused by organic waste such as livestock and poultry breeding, reduce the nitrate content of groundwater, and reduce the nutritionalization of surface water body caused by surface source pollution.The safety and quality of agricultural products, the prevention and treatment of contamination, and the efficiency of ecological environment is extremely significant.

[seed preservation temperature] How long can the seed cold storage storage be reached?

Validity of vegetable seed preservation

Vegetable seed germination rate is very related to the preservation period, different vegetable species, and their preservation years are different.

tomato:Generally, it can be stored for 3-4 years, and the longest does not exceed 4 years. Otherwise, the method of reducing the bud rate will be reduced. The method of identifying the old and new seeds is that there are furry on the new seeds and tomato flavors.

Cucumber:At most 2-3 years, which exceeds this period, the period of the deadline is generally reduced by 20-30%. Even if it can emerge, some often have no true leaves after seedlings, and it is not easy to survive.

eggplant:seeds that are generally within 6 years can be used. The new seeds are shiny, and the old seeds reduce the luster according to the storage period.

chili:It must not exceed 3 years, otherwise the bud rate will be reduced, the bud rate of 2 years will be reduced by about 10%, and the storage of three years will be reduced by about 30%. The new seeds are golden yellow, and the Chen seeds are apricot yellow.

Scallion seed:In the summer, the green onions must be used to use the new seeds of the year. If the seeds of the aged, the green onions will smoke moss.The spring onion can be produced in the first year.

coriander:It must be stored for one year, but the storage time should not exceed 3 years.Otherwise, the fragrance will become smaller.

celery:It can be stored for 3 years. The seeds that year cannot be used in that year, and it must be used for one year.

Chinese chives:The new seeds were good at that time, and the germination rate of two years was greatly reduced.

Chinese cabbage:It can be stored for two years. The seeds harvested in that year can be sowed in that year, but if more than two years, the seedling rate is reduced by 20-30%, and the disease resistance is low.

seed preservation temperature

During the storage period, the percentage of the relative humidity of the air in the storage room plus the temperature((Hua'sCureThe number should not be greater than100Otherwise, it will affect the storage effect.Onions, broccoli, carrots, lettuce, tomato, eggplant and other vegetables are stored in20Percent(66T)The temperature and air relative humidity of the air is50Under the conditions, it can be stored safely.The seeds of cauliflower are stored in17(62..6F)Relative humidity with air is35Under the condition,4During the year, the seeds of seeds remain unchanged.When the temperature is5, the relative humidity of the air is45%one50At %, many seeds can be stored10Year or more time.If the temperature and the relative humidity of the air can be reduced, the effect of seed preservation can be improved.

The maintenance of the seeds of seeds is also closely related to the content of the seeds itself, and reducing the moisture content can extend the seed life.According to research, the moisture content of the seeds decreasesL%, Temperature decrease5..6C can double the life of the seeds.

Of course, the seeds of different varieties of the same vegetable have different reactions of storage conditions.

According to the above principles, the seeds of vegetables are effectively stored effectively((Or other crop seedsCureThere are also many methods. At present, the low -temperature drying storage method or sealing low -temperature storage method is used internationally internationally. The former is mainly to build a low -temperature drying seed library to store seeds.storage at low temperature.According to the test, the seeds of vegetables with low water content are-4storage at low temperature at low temperature20In the year, he still had a high life.Moso seeds with low water content are in a closed container and stored in2Under , pass through10After the year, there is almost no reduction of its living power.

In addition, Chinese cabbage and cabbage are not affordable"Original species" seeds, stored with silicone dryer, put in4-5storage can be stored under the condition ofLOOver the year.
