Embodiment 1

[0033] The proportion by weight of each component is: 9.5 parts of potassium sulfate, 11 parts of ammonium sulfate, 14 parts of monoammonium phosphate, 12 parts of urea, 9.5 parts of medium and trace element additives, 9.7 parts of conditioner, polyaspartic acid or its 0.3 part of salt, 34 parts of humic acid or its salt. Among them, the medium and trace element additives are mixed by zinc sulfate, manganese sulfate, magnesium sulfate, ferrous sulfate, and gypsum powder in a ratio of 1:1:1:1:2 by weight, and polyaspartic acid or its salt is polytianmen Partic acid, humic acid or their salts are ammoniated peat. The conditioner is attapulgite or zeolite powder.

[0034] Preparation:

[0035] The original granulation process is adopted, and its equipment and process are the same as those of the existing granulation method for producing fertilizers. The difference between it and the existing equipment is that two metering machines connected to the granulator are added before th...

Embodiment 2

[0040] The proportion by weight of each component is: 17 parts of potassium sulfate, 7 parts of ammonium sulfate, 14 parts of monoammonium phosphate, 18 parts of urea, 6 parts of medium and trace element additives, 17.6 parts of conditioner, polyaspartic acid or its 0.4 parts of salt, 20 parts of humic acid or its salt. Among them, the medium and trace element additives are mixed by zinc sulfate, manganese sulfate, magnesium sulfate, ferrous sulfate, and gypsum powder in a ratio of 1:1:1:1:2 by weight, and polyaspartic acid or its salt is polytianmen Potassium particic acid, humic acid or a salt thereof is a potassium salt of humic acid. The conditioning agent is attapulgite or zeolite powder.

[0041] Preparation:

[0042] The original slurry method granulation technology is adopted, and its equipment and technology are the same as those of the existing pellet method for producing chemical fertilizers. Mix other components except polyaspartic acid or its salt and humic aci...

Embodiment 3

[0047] Field control test of special fertilizer for garlic of the present invention.

[0048] The experimental location is Zhanglou Farm, Pizhou City, Jiangsu Province. The garlic field covers a total area of ​​5 mu, and 1,000 kg of commercial organic fertilizer is uniformly applied before the garlic field is leveled. Contrast 2.5 mu, apply local conventional compound fertilizer (15-15-15), 150 kilograms per mu; special fertilizer treatment uses the garlic special fertilizer that embodiment 1 produces (additive is the weathering of polyaspartic acid potassium salt and ammoniation treatment) coal) 150 kg per mu. Except for different fertilizers, other field management measures were the same.

[0049] The results showed that compared with the garlic applied with ordinary compound fertilizer, the garlic treated with special fertilizer for garlic had darker green leaves, wider leaves and faster growth. After testing the chlorophyll content in the leaves, the application of spec...

Abstract

The invention discloses a garlic special compound fertilizer containing aspartate and a preparation method thereof. The compound fertilizer is prepared from potassium sulfate, ammonium sulfate, monoammonium phosphate, urea, poly(aspartic acid) or salts thereof, humic acid or salts thereof, medium and trace mineral supplements and a conditioner as raw materials. The invention also provides a preparation method of the compound fertilizer, which comprises equipment and process for producing the fertilizer by using a slurry method and equipment and process for producing the fertilizer by using anaggregating method. The garlic special compound fertilizer can be used for coordinating and stimulating overground and underground parts of the crops so as to promote the root growth of the crops, improves the photosynthetic efficiency, promotes the absorption of the root system to the NPK and trace elements, and completely improves the utilization rate of the fertilizer.

Description

technical field [0001] The invention relates to a special fertilizer for field base fertilizer application of economic crops, in particular to a fertilizer suitable for the production and use of soil in the Xuhuai soil area and the Yishu River soil area of ​​Jiangsu Province. [0002] Background technique [0003] Jiangsu is one of the four main garlic producing areas in China, and Pizhou City is one of the largest white garlic producing areas and white garlic export bases in the country. The city is suitable for garlic planting with more than 1 million acres of arable land, and the garlic field has a stable yield of more than 1,500 kg. The garlic planting area exceeds 600,000 mu, with an annual output of nearly 800,000 tons of dried garlic, an annual export of more than 250,000 tons of garlic, and an annual foreign exchange earning of 150 million US dollars. And formed a relatively complete industrial chain. The garlic industry has become the pillar industry of the local ...
