Description

technical field

[0001] The invention relates to the field of chemical fertilizers used in agricultural and forestry production, in particular to a multi-component water- and fertilizer-retaining compound fertilizer and a preparation method thereof. Background technique

[0002] Fertilizer is the food of plants, an extremely important means of agricultural production, and an important guarantee for the development of agricultural production and national food security. With the continuous development of my country's chemical fertilizer industry and agricultural production, the amount of fertilizer is increasing. Using a large amount of fertilizer will inevitably lead to excessive fertilization, weaken the production capacity of crops, aggravate environmental pollution, and waste a lot of scarce resources. At present, most of the fertilizers used in agriculture and forestry are simple fertilizers. Excessive application of such fertilizers for a long time will inevitably lead to...
