Problems solved by technology

[0003] During the growth of crops, nutrients need to be added, among which drought-resistant and water-retaining fertilizers are one of many fertilizers. The existing drought-resistant and water-retaining fertilizers have a certain water-retaining effect, but the water-retaining performance is short, and the soil is easy to harden after adding drought-resisting and water-retaining fertilizers. It is not conducive to the growth of crops. For this reason, we propose a kind of drought-resistant and water-retaining fertilizer and its preparation method

Abstract

The invention discloses a drought-resistant and water-retaining fertilizer and a preparation method thereof. The drought-resistant and water-retaining fertilizer is prepared from the following raw materials by weight: 20-35 parts of crop straw, 9-16 parts of animal waste, 15-25 parts of chaff powder, 5-9 parts of bagasse, 17-24 parts of urea, 11-15 parts of potassium nitrate, 7-9 parts of an organic acid agent, 8-13 parts of microbial powder and 4-7 parts of starch grafted acrylate. According to the invention, the starch grafted acrylate is added into the drought-resistant and water-retainingfertilizer, the starch grafted acrylate has ultrahigh water absorption rate and water absorption speed, is non-toxic and harmless, can release and absorb water repeatedly, and endows the drought-resistant and water-retaining fertilizer with good water-retaining properties, by adding the organic acid agent composed of alginic acid, oxalic acid and salicylic acid, the organic acid agent can bind soil into a stable aggregate structure to loosen the soil, and the drought-resistant and water-retaining fertilizer added with the organic acid agent can activate phosphorus, potassium and trace elementssolidified in the soil out for crops to absorb and utilize, and the soil is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer materials, and more specifically relates to a drought-resistant and water-retaining fertilizer and a preparation method thereof. Background technique [0002] During the planting process of crops, in order to ensure the normal growth of the crops and obtain high and stable yields, the crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. Drought is one of the most frequent meteorological disasters in my country. In recent years, due to the frequent occurrence of El Niño and La Niña phenomena, abnormal weather conditions have become a common phenomenon, resulting in extremely uneven distribution of rainfall, and droughts have caused crop yields to decline or even fa...
