Abstract

The invention relates to a soil organic matter cultivation functional fertilizer and a preparation method thereof, the carbon-nitrogen ratio of the functional fertilizer is 5.0-30.0, and the functional fertilizer comprises the following raw materials in percentage by weight: 71.0-77.6% of corn straw, 0.4-7.0% of urea, 20% of potassium dihydrogen phosphate, 1.0% of collagen and 1.0% of zeolite powder. According to the invention, different ratios of the corn straw and the urea are utilized to prepare the soil organic matter cultivation functional fertilizers with different carbon-nitrogen ratiosthrough ammoniation treatment, so that the water and fertilizer conservation capacity and nutrient conversion capacity of soil are improved, the fertilizers can be widely applied to the organic cultivation process of farmlands with different soil fertility (especially farmlands with low soil fertility), and the fertilizer is beneficial to the high quality, high efficiency, ecology and sustainabledevelopment of agriculture.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a soil organic matter cultivation functional fertilizer and a preparation method thereof. Background technique [0002] Straw is a by-product of agricultural production, and its output increases with the continuous improvement of grain production. The amount of crop straw resources in my country ranks first in the world. [0003] Crop straw is the largest renewable resource on earth and an important by-product of crops. On the one hand, straw incineration has caused a huge waste of resources; on the other hand, the harmful substances such as sulfur dioxide and phenpropyr released during the incineration process will pollute the air and endanger human health. The scientific return of crop stalks has become a prominent issue in agricultural production, and has attracted more and more attention from society and public opinion. At present, with the development of ...
