Embodiment 1

[0010] An agricultural organic fertilizer, which is prepared by the following method: mix pig manure and corn stalks at a weight ratio of 4:1, and ferment for 5 days to obtain a fermentation mixture; dry the fermentation mixture and mix it with fly ash to obtain an agricultural fertilizer. Organic Fertilizer. The weight ratio of the fermentation mixture to fly ash is 6:1.

Embodiment 2

[0012] An agricultural organic fertilizer is prepared by the following method: mix pig manure and wheat straw according to the weight ratio of 4: 2, and ferment for 6 days to obtain a fermentation mixture; dry the fermentation mixture and mix it with fly ash to obtain the agricultural fertilizer. Organic Fertilizer. The weight ratio of the fermentation mixture to fly ash is 6: 2.

Embodiment 3

[0014] An agricultural organic fertilizer, which is prepared by the following method: mix pig manure and corn stalks at a weight ratio of 4:1.2, and ferment for 5 days to obtain a fermentation mixture; dry the fermentation mixture and mix it with fly ash to obtain the agricultural fertilizer. Organic Fertilizer. The weight ratio of the fermentation mixture to fly ash is 6:1.2.

[0015] Using the agricultural organic fertilizer prepared in Examples 1, 2 and 3 to plant vegetables, the yield of vegetables is increased by 15-20%, and the cost is reduced by 10-20%.

Abstract

The invention provides an agricultural organic fertilizer and relates to the field of agriculture. The agricultural organic fertilizer comprises the following steps: after mixing pig manure with straws, fertilizing to obtain a fertilized mixture; after drying the fertilized mixture, mixing the fertilized mixture with coal ash to obtain the agricultural organic fertilizer. The agricultural organic fertilizer provided by the invention is low in cost and can improve yield of vegetables.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an agricultural organic fertilizer. Background technique [0002] Organic fertilizer (manure) refers to a type of fertilizer made from natural organic matter decomposed or fermented by microorganisms. Also known as farmyard manure in China. Its characteristics are: wide source of raw materials, large quantity; complete nutrient content, low content; slow and long fertilizer effect, it must be decomposed and transformed by microorganisms before it can be absorbed by plants; good effect of improving soil and cultivating fertilizer. Commonly used natural fertilizers include green manure, human excrement, barn manure, compost, retting manure, biogas fertilizer and waste fertilizer. However, the organic fertilizers in the prior art have the disadvantages of high price, slow fertilizer efficiency, and inability to decompose and transform harmful substances generated by soil pesticides or f...
