Problems solved by technology

[0007] In order to solve the problem that existing fertilizers do not have water retention, fertilizer retention, and rapid nutrient loss in agricultural production, resulting in crop yield reduction or loss of harvest, the present invention provides a cheap, high-efficiency water-retention organic fertilizer that does not contain chemical components. Vegetable oil processing produces by-products plant blended oil bran cake and organic waste as the main raw materials. While eliminating the secondary pollution caused by organic waste to the environment, the recycling of resources is realized

Abstract

The invention provides a water-retaining organic fertilizer and a preparation method thereof, which belongs to the technical field of organic fertilizers. The method provided by the invention uses an edible vegetable blended oil bran cake as a main raw material for development of the water-retaining organic fertilizer, and the problems of existence of multiple harmful components caused by addition of chemical materials and single efficacy of products in traditional organic fertilizers are overcome. The water-retaining organic fertilizer is prepared from the edible vegetable blended oil bran cake, organic waste, a conditioning agent and a microbial inoculant. The preparation method comprises the following steps: crushing the edible vegetable blended oil bran cake and the organic waste; then mixing the crushed bran cake and organic waste with the conditioning agent and the microbial inoculant under stirring; and carrying out pool stacking fermentation, stripe-shaped stacking fermentation, screening and granulation so as to obtain the water-retaining organic fertilizer. According to the invention, because of usage of organic matter raw materials containing abundant mycoprotein, the organic fertilizer has a water-retaining function, and the problem of reduced output or poor output of crops caused by lack of water, no retention of water and fertility, no drought tolerance and loss of nutrients in agricultural production is overcome.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and relates to a method for preparing organic fertilizers by using edible plants to blend oil and bran cakes. Background technique [0002] It is understood that the average annual precipitation in 45% of my country's regions is less than 400mm. Agricultural production reduction and desertification caused by drought and soil erosion have become serious natural disasters in my country and even in the world. A reliable means, known as the fourth largest category of agrochemicals after fertilizers, pesticides, and mulch. [0003] At present, most of the water-retaining agent products in China are neither fertilizers nor pesticides, and the main components are some high-molecular polymers. At present, the multifunctional composite long-acting water-retaining agents available on the market, such as polyacrylamide-type water-retaining agents, are expensive, generally more than 30,000 to 50,...
