Abstract

The invention discloses a water conservation type organic fertilizer and a preparation method thereof. The organic fertilizer contains the following raw materials: corn stalks, plant ash, wheat bran,bean dregs, humic acid, urea phosphate, distillers' grain and a water-retaining agent. The concrete steps are as follows: (1) mixing the corn stalks, plant ash, wheat bran, bean dregs, humic acid, urea phosphate and distillers' grain, and transferring the mixture into a fermentation tank, adding water until the water content is 50-60%, carrying out sealed fermentation, then drying ferment materials, and grinding to prepare fermented material powder; and (2) adding the water-retaining agent into the fermented material powder, stirring and granulating to prepare the organic fertilizer. The waterconservation type organic fertilizer is simple in preparation process, low in cost, free from pollution to soil, can meet the nutrients demanded by plant growth, has effects of improved soil structure, increasing of gas permeability of soil and reduction of water loss and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing, and in particular relates to a water-retaining organic fertilizer and a preparation method thereof. Background technique [0002] Drought and water shortage have seriously restricted the development of my country's agriculture and accelerated land desertification. my country's agricultural water consumption accounts for about 80% of the total consumption of water resources. However, the lack of water resources makes agriculture must take the path of water-saving development. Therefore, improving the utilization rate of agricultural water resources is the central task of my country's agricultural development. With the increasing environmental pollution and the decrease of green vegetation year by year, it poses a severe test to the living environment of human beings. The water in the soil is easy to lose, causing problems such as soil compaction and soil desertification. Ther...
