Brief：
Polyaspartic acid (PASP) is a kind of water soluble, biodegradable ,non-toxic ,chemosynthetic amino acid polymer. it is condensation polymer linked by peptide bond formed by L-aspartic acid amnio groups and carboxyl groups. It is macromolecular structure moreover with much free amino and carboxyl groups. the molecular weight scope is from 1000 to 5000 Dalton.
Functional mechanism of PASP in agriculture:
1 . 100% water solubility make it more convenient and economic for user to foliar spray and drip irrigation ,moreover, improve the solubility of some ions (such as Ca Mg) in irrigation water and be against sedimentation.
2. 5% low molecular weight containing in PASP，which are easily decomposed to single L-aspartic acid and to promote chlorophyll synthesis and photosynthesis, push nutrition matters transporting to fruits , improve the yield and increase the quality, Promote the resistant matters generation, Increases tolerance of plant against drought, cold, disease and heat.
3. 75% highly molecular weight containing in PASP ,which are three-dimensional winding structure and with huge quantities free amino and carboxyl groups, it can chelate nutrients to reduce N loss and be against p and k fixed by cation irons, to improve the utility of them .
4. Enhance root cell division and improve the soil structure and fertility, be good to root vigor, enlarge root hair region.
Usage:
apply on the plants directly
