II. Features
Strong gel strength Increase the permeability of the soil
Three, applicable
Suitable for loamy soil and clay soil Crops, flowers, potted plants, fruit and vegetable seedlings, trees
IV. Problems
1. What are the reasons for the strong gel strength?
High degree of cross-linking? Is there any difference in cross-linking agent content and polymerization time of preparation process?
2. What is the reason for increasing the permeability of the soil?
3. The effect of increased gel strength on other properties
4. the service life can be increased?
5. DK and X contain different amounts of potassium, the effect on the product effect (Russia) X series of high potassium content?
① X series with high potassium content will have better wall protection
② DK is more suitable for fertile soil and dry and water-scarce places.
