Embodiment Construction

[0022] The embodiment of the present application provides an organic fertilizer, including a basic composition, a mineral composition, and humus or a microbial liquid obtained by culturing humus;

[0023] The humus soil is collected from the surface of the mountain or the forest for many years with the humus dead leaves, dead grass and leaf soil. The humus soil contains a variety of natural biological bacteria, which can decompose fermented plant straw, cow dung, etc., without any side effects.

[0024] The basic composition includes cow dung, corn cobs, rice husks, wood residue and rice bran;

[0025] Cow dung, rice husk, wood slag, corncob, etc. have a certain softening effect, and combine with the compacted soil to increase soil voids, facilitate soil ventilation, and increase soil oxygen content and fertilizer absorption capacity. Combined with organic fertilizers to form acidic fertilizers, it can adjust the pH of the soil and reduce the salinity of the soil.

Abstract

The invention discloses an organic fertilizer and a preparation method thereof. The organic fertilizer comprises a basic composition, a mineral composition, and humus soil or a microbial liquid cultured by using humus soil; wherein the basic composition comprises cattle manure, corncobs, rice husk, wood residue and rice bran; the mineral composition comprises biotite, sodium silicate, red soil powder and humic acid. The organic fertilizer prepared by the invention can meet the nutrition supply and demand of rice in the whole growth period, and can provide N, P, K, Ca and trace elements required by the rice growth period under the ensured condition that rice fertilizer removal is not caused. Cattle manure, rice husk, wood residue and corncob have a certain softening effect and are combinedwith hardened soil, so that soil porosity is increased, soil ventilation is facilitated, and the soil oxygen content and the fertilizer absorption capacity are improved. The organic fertilizer not only can improve the soil structure and avoid environmental pollution, but also can improve the quality and yield of rice.

Description

technical field [0001] The application relates to the field of agricultural technology, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] The macronutrient elements nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crops, especially rice growth, and fertilizers containing nitrogen, phosphorus, and potassium need to be supplemented. At present, the commonly used fertilizers are mainly chemical fertilizers. Chemical fertilizers are fertilizers made by chemical methods that contain one or several nutrients needed for the growth of crops. Long-term use of chemical fertilizers can easily lead to reduced soil microbial activity, nutrient imbalance, nitrate accumulation, soil acidification and compaction, etc., resulting in environmental pollution. Contents of the invention [0003] The purpose of this application is to provide an organic fertilizer and a preparation method thereof, so as to sol...
