Embodiment approach 1

[0008] The compound fertilizer of this attapulgite mixes 30% urea, 10% monoammonium phosphate, 25% potassium chloride, 25% ammonium chloride, and 11.5% attapulgite by weight percentage to form Bagging.

[0009] The granulation rate of the compound fertilizer containing attapulgite increased by 10%. After being used in a 3 mu soybean experimental field, compared with the application of ordinary fertilizer, the soybean yield increased by 24%, the quality of agricultural products was also improved, and the soil fertility increased.

Embodiment approach 2

[0011] The compound fertilizer of the attapulgite is according to weight (kg): 300 kg of urea, 100 kg of monoammonium phosphate, 250 kg of potassium chloride, 250 kg of ammonium chloride, and 115 kg of attapulgite. bag.

[0012] The granulation rate of the compound fertilizer containing attapulgite increased by 11%. After being used in a 3 mu soybean experimental field, compared with the application of ordinary fertilizer, the soybean yield increased by 24%, the quality of agricultural products was also improved, and the soil fertility increased.

Abstract

The invention relates to compound fertilizer containing attapulgite. The compound fertilizer containing the attapulgite comprises, by weight (percentage): 30% urea, 10% monoammonium phosphate, 25% potassium chloride, 25% ammonium chloride, and 11.5% attapulgite. Accuracy of the components is plus-minus 5%. The compound fertilizer containing the attapulgite is free of pollution, capable of adjusting soil hardening and improving yield of crops and quality of products, is improved in effective granulation efficiency, is reduced in production cost, is simple in manufacture technology, can overcome defects existing in existing compound fertilizer granulation technology, is easy to popularize.

Description

technical field [0001] The invention relates to a special fertilizer for agricultural products, in particular to a compound fertilizer containing attapulgite. Background technique [0002] At present, there are many types of compound fertilizers, but none of these compound fertilizers can effectively improve the soil compaction caused by a single fertilizer for a long time, cannot effectively adjust the pH of the soil, and cannot improve the production yield and product quality of crops. The harvest has brought great losses, and has caused certain harm to people's health. In addition, in the compound fertilizer granulation process, clay minerals are commonly used as binders, carriers and conditioners. Since most compound fertilizer factories determine the types and proportions of clay minerals used empirically, the effective granulation rate of compound fertilizers is often not high and unstable, resulting in too much return, which seriously affects the compound fertili...
