Abstract

The invention relates to a water-holding and cultivating functional compound fertilizer, comprising a nitrogen fertilizer, a phosphate fertilizer a potash fertilizer, a trace element fertilizer, a compound amino acid, a soil conditioner, an organic matter and the like. In addition, the invention relates to a preparation method of the water-holding and cultivating functional compound fertilizer. The invention also relates to use of the water-holding and cultivating functional compound fertilizer for improvement of the growth characters and / or yield of crops.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound fertilizer with water-retaining and loosening functions and its preparation method and application. Background technique [0002] At present, a large amount of fertilizers are used in agricultural production, but only a small part of the nutrients can be absorbed by plants. This is mainly because the application of a large amount of inorganic fertilizers will cause soil compaction, which is not conducive to the absorption of nutrients by plants. In addition, the absorption of plant nutrients is related to the soil moisture content, and the soil moisture content is small, which is not conducive to the absorption of nutrients by crops. [0003] CN1844060A discloses a liquid fertilizer, which is made of the following raw materials in parts by weight: 140-160 parts of nitrogen fertilizer, 100-120 parts of potassium fertilizer, 100-110 parts of phosphate fertilizer, 120-150 parts...
