Problems solved by technology

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 yield of organic vegetables.
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. Vegetables are completely operated in accordance with the production standards of organic agricultural products, and the safety of their products is difficult to guarantee
The existing organic fertilizer fermentation technology generally ferments all the raw materials together to release most of the nutrients in the organic matter, which is unfavorable for the later fruit growth of solanaceous vegetables
If organic fertilizer is topdressed and applied on the soil surface, the effect is not good, and fertilization by digging trenches will damage the root system of vegetables
To solve the above problems, it is necessary to change the existing organic fertilizer production mode, so that the nutrient release in the organic fertilizer meets the nutrient absorption requirements of solanaceous vegetables, and there is no report on this aspect so far

Embodiment 1

[0041] Embodiment 1: special organic fertilizer for solanaceous organic vegetables, the mass parts of raw material components are as follows:

[0042] Furfural residue 300 parts

[0043] Cottonseed hulls 400 parts

[0044] Weathered coal 200 parts

[0045] Cake 100 parts

[0046] Microbial fermentation agent 20 parts.

[0047] (1) Raw material preparation

[0048] The furfural slag is crushed into small pieces with a particle size of less than 2 mm, aired until the moisture content is below 25 wt%, the cottonseed hulls are crushed through a 10-mesh sieve, and the cake is crushed through a 20-mesh sieve.

[0049] (2) Take 400 parts of cottonseed hulls, 200 parts of weathered coal and 10 parts of microbial fermentation agent and mix well. Adjust the moisture of the mixture to be 55wt%, pH7. Fermented 21 days by prior art. Another 10 parts of microbial fermentation agent and 300 parts of furfural slag were mixed with the above-mentioned fermented raw materials, adjusted to...

Embodiment 2

[0053] (1) Raw material preparation: crush the furfural slag into small pieces with a particle size less than 3 mm, dry the moisture content to below 25 wt%, crush the cottonseed hulls and pass through a 10-mesh sieve, and crush the cake through a 20-mesh sieve.

[0054] (2) Take 450 parts of cottonseed hulls, 150 parts of weathered coal and 8 parts of microbial fermentation agent and fully mix them evenly. Adjust the moisture of the mixture to be 60wt%, pH7.5. Fermented 18 days by prior art. Another 8 parts of microbial fermentation agent and 250 parts of furfural slag were mixed with the above-mentioned fermented raw materials, adjusted to 60 wt% moisture and pH 7.2, and then fermented for 21 days. Get fermented material.

[0055] (3) Soak 150 parts of the cake in 300 parts of water for 12 hours, boil for 15 minutes, add the liquid together with the above fermented material and mix evenly, and granulate according to the prior art to obtain a granular fertilizer product.

Embodiment 3

[0058] (1) Raw material preparation is the same as in Example 1.

[0059] (2) Get 300 parts of cottonseed hulls, 250 parts of weathered coal and 5 parts of microbial fermentation agent, wherein all of cottonseed hulls and weathered coal, and 1 / 2 of microbial fermentation agent are fully mixed evenly. Adjust the moisture of the mixture to be 65%wt, pH7.2. Fermented 14 days by prior art. Another 5 parts of microbial fermentation agent and 400 parts of furfural slag were mixed with the above-mentioned fermented raw materials, adjusted to 65 wt% moisture and pH 7.0, and then fermented for 24 days. Get fermented material.

[0060] (3) Soak 50 parts of the cake in 100 parts of water for 10 hours, boil for 25 minutes, add the liquid together with the above-mentioned fermented material and mix evenly, and dry the water content to 20wt% to obtain a powder product.

[0061] This fertilizer is especially suitable for tomatoes, peppers or bell peppers.

Abstract

The invention relates to a special organic fertilizer for solanaceous fruit organic vegetables and a preparing method thereof. The organic fertilizer is prepared from the following components in parts by weight: 250-400 parts of furfural, 300-450 parts of cotton seed hulls, 150-250 parts of weathered coal, 50-150 parts of grouts and 10-20 parts of microorganism fermentation strains. According to the nutrient requirement of the solanaceous fruit vegetable and the nutrient content of various organic matters, the special organic fertilizer is prepared from different organic raw materials through mixing and fermentation, has strong pertinence, and is free from harmful substances. According to the difficulty degree of the fermentation and decomposition of various raw materials, the fermentation and rotten are carried out by sections, therefore, the nutrient release time in the final product satisfies the absorbing requirements of the solanaceous fruit vegetables, the vegetable is strong in the time of infertility, and has high yield and good quality.

Description

technical field [0001] The invention relates to a special organic fertilizer for organic vegetables, in particular to a special organic fertilizer for solanaceous organic vegetables and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] At present, in the process of planting vegetables, chemical fertilizers, pesticides, herbicides and plant growth regulators are often used. Although the production level has been greatly improved, it has also brought a variety of harmful substances in the products. Health poses a threat. Therefore, healthy and safe organic vegetables are increasingly recognized by domestic and foreign consumers. [0003] The so-called organic vegetables refer to organic agricultural production systems, where the quality of the ecological environment meets the specified standards, do not use any harmful chemically synthesized pesticides, chemical fertilizers and other chemical substances in t...
