Composite polysaccharide fertilizer synergist and preparation method thereof

Abstract

The invention belongs to the field of biological preparations and discloses a composite polysaccharide fertilizer synergist and a preparation method thereof. The synergist is prepared from, by weight, 0.1-1 part of xanthan gum, 0.1-1 part of Welan gum and 0.001-1 part of polyglutamic acid. The invention further discloses a preparation method and application of the fertilizer synergist. The synergist is natural and free of pollution, has the effect of regulating growth of crops, stimulates vitality of the crops, increases the absorption rate of the crops, improves nutrient absorption efficiency of the crops, increases the utilization rate of fertilizer, and improves the quality of the crops. Thus, the synergist is mixed with the fertilizer to be used, so the yield of food crops, leafy vegetables, melons, fruits and other crops can be effectively increased, and the quality can also be greatly improved.

Description

technical field [0001] The invention relates to the technical field of biological preparations, in particular to a compound polysaccharide fertilizer synergist and a preparation method thereof. Background technique [0002] At present, the utilization rate of chemical fertilizers in my country is not high, and the utilization rate of nitrogen fertilizer in the current season is only 35%. The low fertilizer utilization rate has always been a problem in China's agricultural fertilization. At the same time, the large-scale application of chemical fertilizers has also caused serious pollution to the environment. For example, heavy metals and toxic elements have increased, microbial activity has decreased, substances are difficult to transform and degrade, nutrient imbalance, nitrate accumulation, acidification intensified, and pH changes are too large. Therefore, improving the utilization rate of chemical fertilizers is of great significance to the sustainable development of ag...
