Problems solved by technology

Because farmers pay more attention to the economic benefits of garlic, the fertilization is mainly nitrogen fertilizer (urea-based). The common problem of current fertilization is that the C / N ratio of the soil is out of balance, and the carbon and nitrogen content of the farmland soil has not been effectively controlled. In addition, improper fertilization leads to The stress resistance of garlic gradually decreases, the nitrogen absorption and utilization rate is low, and the risk of nitrogen loss increases
In addition, with the vigorous development of the breeding industry in various places, the proportion of farmers stacking animal manure at will is very large, and the time control of returning animal manure to the field is unreasonable, which makes the nutrient loss of animal manure serious, and it is easy to cause Water and groundwater pollution

preparation example Construction

[0023] The above-mentioned preparation method of the organic soil substrate for garlic, comprises the steps:

[0024] ①Press the fresh straw to dehydrate the fresh straw and remove the small molecular carbon; cut the fresh straw into 10cm with a cutting machine and press it to reduce the moisture of the fresh straw to less than 30%; Carbon refers to the removal of small molecules such as monosaccharides and polysaccharides in fresh straws by pressing fresh straws to achieve carbon source filtration.

[0025] 2. Mixing poultry and livestock manure and organic biological residues with the pressed fresh straw to form fermentation raw materials, so as to adjust the C / N of the pressed fresh straw; and organic biological residues.

[0026] ③ The fermentation raw materials are decomposed by "anaerobic high-temperature fermentation". The fermentation time of anaerobic high-temperature fermentation is 10 days, and the temperature rises to 60-70 °C, so as to remove the easily decomposa...

Embodiment 1

[0040] Example 1: Organic soil substrate for garlic with corn stover and cow dung as main raw materials

[0041] Cow dung 80%

[0042] Corn stover 20%

[0043] The preparation process of the organic soil substrate for garlic is as follows:

[0044]Squeeze fresh straw to dehydrate and remove small molecular carbon, so that its organic matter is mainly to alleviate organic matter; use livestock manure and organic biological residues to mix with fresh straw after pressing to become fermentation raw materials, so as to adjust the fresh straw after pressing. The C / N of the straw; ensure that the C / N of the organic fertilizer substrate after fermentation is 30-40; the fermentation raw materials are decomposed by "anaerobic high-temperature fermentation" to remove the perishable organic matter in the fermentation raw materials, so that they can be used for The content of perishable organic matter in the organic soil matrix of garlic is less than 5%; the fermentation time of anaer...

Embodiment 2

[0047] Example 2: Organic Fertilizer Matrix with Corn Stalk and Chicken Manure as Main Raw Materials

[0048] This embodiment is prepared according to the following raw materials:

[0049] Chicken Manure 40%

[0050] Corn stover 60%

[0051] The preparation method is the same as in Example 1, and the field test can also have a good yield-increasing effect on garlic.

[0052] Garlic field experiments were carried out in the Erhai River Basin of Dali Prefecture, Yunnan. The treatment settings are: blank - do not apply any fertilizer; habit - farmers are used to fertilizing, organic fertilizer 0.6t / mu, chemical fertilizer nitrogen (N) 45kg / mu, chemical fertilizer phosphorus (P 2 o 5 )12kg / mu, chemical fertilizer potassium (K 2 O) 25kg / mu; organic fertilizer substrate - apply the substrate 0.6t / mu, evenly cover the substrate on the garlic seeds, cover soil, chemical fertilizer nitrogen (N) 25kg / mu, chemical fertilizer phosphorus (P 2 o 5 )12kg / mu, chemical fertilizer pota...

Abstract

The invention belongs to the field of agricultural environmental protection and particularly relates to an organic ridging matrix for garlic and a preparation method thereof. The preparation method comprises the following steps of: pressing fresh straw to remove water and micromolecular carbon from the fresh straw; mixing livestock and fowl manure, organismal residual bodies and the pressed freshstraw to prepare fermentation raw materials; decaying the fermentation raw materials by anaerobic high temperature fermentation to remove organic matters which are easy to decay; and cooling, drying,grinding and sieving the fermentation raw materials which are totally decayed to obtain the organic ridging matrix. The organic ridging matrix for the garlic of the invention has higher C / N ratio, can be used for fixing inorganic nitrogen, can activate organic nitrogen in soil and reduce nitrogen loss, can meet nutrient substances required by crop growth, overcomes the defects of imbalanced C / N ratio and ineffective control of the carbon and nitrogen content of farmland soil after the conventional fertilizer is used, has excellent effect in the aspects of developing ecological agriculture andenvironmental-friendly agriculture and protecting soil resources and improves the utilization rate of agricultural wastes.

Description

technical field [0001] The invention relates to the field of agricultural and environmental protection, in particular to an organic earth-building substrate for garlic and a preparation method thereof. Background technique [0002] At present, the amount of chemical fertilizer application on cultivated land in my country is on the rise. Excessive fertilization of economic crops and low nutrient utilization rate are the problem, one of the important reasons is the imbalance of soil C / N ratio. The content, proportion and existing forms of carbon and nitrogen in farmland soil are one of the main factors affecting the ecological regulation function and fertility level of soil nutrients. In recent years, garlic has become one of the main economic crops planted by farmers in some areas. The root system of garlic is shallow, with few root hairs, weak fertilizer absorption ability, and relatively high requirements for the quantity and quality of fertilizers. Because farmers pay mo...
