Problems solved by technology

General fertilizers only provide nutrients to crops, and the effect of using them in water-deficient areas in my country is not obvious enough. Many fertilizers are applied in the field all year round and cannot be dissolved or absorbed by crops. The main reason is that the soil lacks water, so that the effect of fertilizers cannot be achieved. Take full advantage or not

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] A kind of anti-drought and moisturizing fertilizer, which is composed of agricultural ammonium, ammonium phosphate, potassium, water retaining agent and coating agent, wherein the weight percentage of each component is,

[0016]

[0017] A preparation method for drought-resistant and moisturizing fertilizer, the steps are:

[0018] (1), each component is carried out metering batching;

[0019] (2) Roughly crush the measured components into powder, with a particle size of less than 0.5 mm;

[0020] (3), granulation, the particle size is controlled at 2-5mm;

[0021] (4), drying and cooling, the temperature during drying is 320-340 ℃;

[0022] (5) sieving to ensure that the particle size is 2-4mm;

[0023] (6) Just pack it.

Abstract

A drought-resistant moisture-retaining fertilizer and a preparation method thereof relate to the technical field of fertilizers, and the drought-resistant moisture-retention fertilizer is characterized by comprising 32-34% of agricultural ammonium chloride, 35-40% of ammonium phosphate, 20-25% of potassium, 2-3% of a water-retaining agent, and 0.05-1% of a coating agent. The preparation method comprises the following procedures of weighing of each components, coarse crushing, granulation, drying and cooling, screening, and packaging. The fertilizer of the invention can fully retain water when rainwater is abundant so as to maintain soil moisture, and can slowly release nutrients during drought and water shortage; therefore, not only water required by crops is ensured, but also the fertilizer efficiency is ensured, and the yield is improved by 10-30%.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a drought-resistant and moisturizing fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is the food of plants, and fertilization is an essential means to ensure high and stable crop yields in the agricultural production process. In recent years, with global warming, my country's annual average temperature has risen, regional precipitation and river runoff fluctuations have increased significantly, extreme weather and climate events have increased, drought disasters have shown a trend of increasing, and the scope of drought has continued to change from The rural area has expanded to the city and the ecological environment, and the area of ​​drought has also expanded from the west and north to the east and south. In the grain-producing areas of the North China Plain, due to the perennial overexploitation of groundwater, a large number of underg...
