Problems solved by technology

[0004] At present, there are still many problems to be studied in the application of water-retaining agents in agriculture. For example, due to the influence of various factors (soil structure, moisture, temperature, ventilation conditions, etc.) Only under certain conditions can it be absorbed and utilized by plants, resulting in insignificant effects on crop yield, drought resistance and fruit quality.

example 1

[0036] This test takes Jiangnan No. 3 as the test material in Yangxian Tobacco Area, and adopts field experiments to analyze the combined application of inorganic fertilizer (special fertilizer for tobacco) and the drought-resistant and water-retaining organic fertilizer prepared by the present invention and the integration of inorganic fertilizer and tobacco-specific charcoal base. The effects of combined fertilizer application on nitrogen and potassium content, photosynthetic characteristics, agronomic and economic traits of flue-cured tobacco are shown in the table below.

Abstract

The invention provides an organic fertilizer for drought resistance and water retention of plants as well as a preparation method thereof. The organic fertilizer comprises organic fertilizer coating particles; the organic fertilizer coating particles are prepared by the following components in parts by weight: 780-820 parts of organic fertilizer particles and 180-220 parts of a water-retaining agent which is coated on the surfaces of the organic fertilizer particles; the organic fertilizer particles are prepared by the following components in parts by weight: 150-300 parts of biochar, 1-5 parts of trace elements, 10-30 parts of a biological bacterial fertilizer, and 600-700 parts of fermented animal manure. The biochar and the animal manure fermentation products are used as main components of the organic fertilizer, trace elements and the biological bacterial fertilizer are added, the water-retaining agent is used as a cheap carrier, the water-retaining agent is used for coating the organic fertilizer, so that the organic fertilizer for drought resistance and water retention of plants is prepared; the fertilizer has the advantages of good drought resistance, water retention, fertilizer conservation, low cost, simple application method, reduced pollution to soil environment, and the like, and the fertilizer is good for ecological balance.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a plant drought-resistant and water-retaining organic fertilizer and a preparation method thereof. Background technique [0002] Moisture conditions are the main conditions that determine the type of agricultural development. Due to its high frequency of occurrence, long duration, wide range of impacts, and large after-effects, drought has been the first disaster that endangers agricultural and animal husbandry production since ancient times. With the economic development and population expansion of human beings, the shortage of water resources is becoming more and more serious, and the trend of aridification has become a global concern. Therefore, drought has become one of the restrictive factors in agricultural development. [0003] Biochar is rich in organic carbon, which can increase soil organic carbon content, as well as soil organic matter or humus content, thereb...
