Embodiment 1

[0025] The organic fertilizer of the present embodiment comprises the following components by weight:

[0026] The present embodiment is made up of the following raw materials by weight: 300 kg of cow dung, 400 kg of sheep dung, 20 kg of peat, 2.5 kg of microbial inoculum, 30 kg of leguminous crops, 5 kg of alfalfa, 6 kg of discarded leaves of Chinese cabbage, 5 kg of leek, wood acid Liquid 2kg.

[0027] The method that present embodiment utilizes cattle and sheep dung to prepare organic fertilizer comprises the following steps:

[0028] 1) Air-dry 300kg of cow dung and 400kg of sheep dung to adjust the water content to 65%. With the total carbon and total nitrogen content of cow dung and sheep dung at 25:1, mix peat into cow dung and sheep dung respectively 18kg and 23kg respectively.

[0029] 2) Add 1kg and 1.5kg of microbial agents to the ingredients obtained in step 1) and cow dung and sheep manure respectively, adjust the pH to 6.8 and 6.9 respectively, stack them into ...

Embodiment 2

[0038] Dry 400kg of cow dung and 300kg of sheep dung in the air to adjust the water content to 55%. With the total carbon and total nitrogen content of cow dung and sheep dung at 25:1, add peat to cow dung and sheep dung respectively. 25kg and 11kg.

[0039] Add 1.5kg and 1.0kg of microbial agents to cow dung and sheep manure respectively, adjust the pH to 6.8 and 6.9 respectively, pile them up into ladders, attach plastic films to them, ferment at 40°C, and turn the pile every 10 days. Replenish water once every 20 days, and ferment for 50 days. After 50 days, the conductivity is 3.7ms·cm-1 and 3.8ms·cm-1. The leguminous crop mung bean was killed at 100° C. for 25 minutes, and pulverized with a pulverizer with a pulverization diameter of 50 mm. After mixing 300kg of cow manure, 400kg of sheep manure, and 1kg of leguminous crops, the organic fertilizer is initially prepared. Mix 2kg of alfalfa, 2kg of Chinese cabbage, 2kg of discarded cabbage leaves, and 1kg of leek leaves, ...

Embodiment 3

[0044] The ingredients and proportioning of the organic fertilizer used in this example are the same as those in Example 1, except that in Example 3 peppers are grown in facility greenhouses for comparative testing. Pepper cultivation experiments were applied in the same amount as conventional farm fertilizers. The test results showed that the pepper seedlings grew vigorously, and the plant height, stem diameter, root length, and dry and fresh weight were all higher than conventional farm fertilizers, and the pepper yield increased by 15%.

Abstract

The invention discloses a method for preparing organic fertilizer from cow dung and sheep manure. According to the method, the cow dung and the sheep manure are taken as main raw materials and added with other auxiliaries for preparation of the organic fertilizer with a fermentation technology. The organic fertilizer prepared with the method has low cost and is simple and convenient to apply, the sheep manure and the cow dung can be composted effectively, nutrient conversion and germ egg killing effects are obvious, the utilization rate of the sheep manure and the cow dung is increased, and a fermentation product has no toxic effect on crops; besides, leguminous crops and waste vegetable leaves are reasonably used, the soil porosity can be improved effectively and the physical and chemical properties of soil can be improved after the fertilizer is applied. With application of the organic fertilizer, the effects of moisture and fertility preservation and high fertilizer supply capacity can be realized, the applying quantity of the fertilizer can be regulated according to different soil and weather conditions, and the organic fertilizer is widely applied to cultivation, seedling culture and the like of various crops.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to organic fertilizers in fertilizers, in particular to a method for preparing organic fertilizers by utilizing cow and sheep dung. technical background [0002] Organic agriculture is a production system that does not use or basically does not use synthetic fertilizers, pesticides, growth regulators and livestock feed additives. Organic fertilizer refers to a type of fertilizer made from natural organic matter decomposed or fermented by microorganisms. It is also called farmyard manure in China. After the organic fertilizer decomposes, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products. Adding alfalfa to the soil, the volatile substances released by it can quickly increase the activ...
