Problems solved by technology

However, the problem of fertilization in the production of organic agricultural products has not been well resolved, and the varieties of organic fertilizers mainly come from existing products on the market
Therefore, there are two problems. One is that the nutrient content of organic fertilizer is unstable, and the ratio of main nutrient elements is unreasonable, resulting in a significant reduction in the output of organic food.
Second, some organic fertilizers contain harmful substances. For example, organic fertilizers produced with animal manure as the main raw material contain feed additive residues, and organic fertilizers produced with biochemical sludge from sewage treatment plants as the main raw material contain heavy metals. It is completely operated in accordance with the production standards of organic agricultural products, and the safety of its products is difficult to guarantee
At the same time, because these crops use underground tubers as harvest products, and the growth and expansion of tubers and the growth of aboveground vines interact and restrict each other, it is necessary to regulate the supply speed and quantity of nitrogen in fertilizers to achieve coordinated growth of the two. The production mode of ordinary organic fertilizers difficult to meet this requirement

preparation example Construction

[0015] The preparation method of the special organic fertilizer for the cultivation of potato and taro crop organic agricultural products of the present invention, the steps are as follows:

[0016] (1) Raw material preparation

[0017] The moisture content of crop seedlings and tendrils should be air-dried to below 60% when used immediately; the moisture content of crop seedlings and tendrils should be air-dried to below 20% when stored for use;

[0018] The cake was crushed through a 20-mesh sieve.

[0019] (2) Weigh crop seedlings, tobacco residues and microbial fermentation inoculum according to the above formula, and mix them evenly. Adjust the water content of the mixed material to 55-60 wt%, and ferment for 35-45 days to obtain the fermented material. Fermentation conditions are according to well-known techniques in the art, and are not particularly limited. (3) Soak the cake in water for 8-12 hours, steam or boil it for 15-30 minutes, add it together with the liquid...

specific Embodiment approach

[0035] The present invention will be further described below in conjunction with the examples, but not limited thereto.

[0036] The raw materials in the embodiment are as follows:

[0037] The content of organic matter in the soot residue is 53.21wt%, the content of total nitrogen is 1.73wt%, the content of total phosphorus is 1.17wt%, and the content of total potassium is 1.20wt%. Tobacco leaf residue discarded during the production process of China Tobacco Henan Industrial Company.

[0038] The cake is soybean meal, a by-product of soybean oil production by Shandong Everbright Sun Moon Co., Ltd., with a total nitrogen content of 2.00wt%, total phosphorus 0.56wt%, and total potassium 0.06wt%.

[0039] The microbial fermentation agent is EM composite agent, produced by Jiangxi Tianyi Biotechnology Development Co., Ltd.

[0040] The amounts and parts of raw materials in the examples are parts by mass, and all percentages are percentages by mass.

Embodiment 1

[0042] The crop vines used are cucumber plants, also called cucumber vines, which are taken from Tai'an City, Shandong Province. Calculated on an air-dry basis, the total nitrogen content is 1.79 wt%, total phosphorus 0.57 wt%, and total potassium 3.16 wt%.

[0043] The mass parts of raw material components are as follows:

[0044] Cucumber vines 700 servings

[0045] Smoke residue 250 parts

[0046] 50 servings of cake

[0047] Microbial fermentation agent 20 parts

[0048] (1) Raw material preparation

[0049] The water content of cucumber seedlings and vines is air-dried to 60%, and the length is cut to 2 cm, and the cake is crushed and passed through a 20-mesh sieve.

[0050] (2) Weigh the cucumber vines, tobacco residue and microbial fermentation agent according to the formula, and fully mix them evenly. Adjust the moisture content of the mixture to 60%, and the carbon-nitrogen ratio and pH value are natural. Ferment for 45 days to obtain fermented material.

Abstract

The invention relates to an organic fertilizer special for cultivating tuber vegetable organic farm products and a preparation method thereof. The organic fertilizer is prepared by mixing and fermenting crop seedling tendrils serving as a main material and scarp, cakes and microorganisms. The special organic fertilizer is prepared by mixing and fermenting according to the requirement of tuber vegetable crops on nutrients and various organic matters, and has reasonable nutrient proportion and strong pertinence. The wasted tendril plants are used for producing the organic fertilizer, so a new source of raw materials is increased.

Description

technical field [0001] The invention relates to a special organic fertilizer, in particular to a special organic fertilizer for the cultivation of yam-like organic agricultural products and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] At present, the global organic food market is growing at an average annual rate of 20% to 30%, and it is expected to reach 100 billion US dollars in 2010. China's organic food is also in a period of rapid development. In 2005, the domestic sales of organic food were 3.71 billion yuan, the export was 136 million US dollars, and the total certified area was 1.655 million hectares. By the end of 2006, domestic sales of organic food reached 5.6 billion yuan. In 2007, the market size has reached 6.17 billion yuan, and there are more than 2,300 domestic organic food manufacturers. However, the problem of fertilization in the production of organic agricultural products has no...
