Abstract

The invention discloses a value-added stress-resistant fertilizer aid and a preparation method, and relates to the technical field of agricultural science and technology. The value-added stress-resistant fertilizer aid comprises 84-94 wt% of a fertilizer value-added factor and 6-16 wt% of a crop stress-resistant factor; the fertilizer value-added factor is prepared from 1-5 wt% of polyaspartic acid calcium zinc, 0.1-0.5 wt% of DMPP and 78.5-92.9 wt% of a modified adsorbent; the modified adsorbent is a mixture of attapulgite and diatomite which are dried and crushed to 200-300 meshes at a high temperature; and the crop stress-resistant factor is prepared 1-10 wt% of alginate oligosaccharide, 0.5-4 wt% of chitosan oligosaccharide and 0.2-1 wt% of oligomeric acid. The value-added and stress-resistant fertilizer aid not only can increase the yield of crops, but also can improve the stress resistance of the crops, and overcomes the problem of deterioration of physical and chemical properties of soil due to application of a large amount of chemical fertilizer all the year round.

Description

technical field [0001] The invention relates to the technical field of agricultural science and technology, in particular to a value-added stress-resistant fertilizer additive and a preparation method thereof. Background technique [0002] Studies have shown that there is a law of diminishing returns in the relationship between fertilization and yield: the more fertilization, the lower the utilization rate of fertilizer, the less the yield of increased crops per unit of fertilization, and excessive fertilization may even cause production reduction and pollute the environment. The main reasons are: [0003] 1. Low technical content of fertilizer products; [0004] 2. The level of fertilization technology is low; [0005] 3. The soil is compacted, and the effect of water and fertilizer retention is poor; [0006] 4. Crops are affected by adversity environments such as salinity, cold, drought, and disease, and the root growth is weak, which affects the absorption and utiliza...
