First, the introduction of zinc humic acid urea
1, the value of the added urea product color is brown to black, nitrogen content of not less than 46%, in accordance with the national standard of urea nitrogen content (GB2440-2001);
2, the efficiency is obvious, add the synergistic agent with conventional detection;
3, the synergistic agent for the plant source of natural substances and extracts, to the environment, crops and human body harmless;
4, the zinc humic acid synergist, trace zinc, humic acid content is more than 0.12%, ammonia volatilization inhibition rate was higher than 10%.
Two, product features
1, adding active agent, high nutrient utilization;
2, natural root inducing agent, deep root seedlings;
3, chelate trace element zinc, nutrition is more comprehensive;
4, fast long-term combination, safety and increase production.
Three, test verification
Zinc humic acid products in the country to establish a demonstration network in 17 provinces of Heilongjiang, Jilin, Xinjiang, Shaanxi, Shandong, Henan, Hunan, Zhejiang, Hubei, Jiangxi, Chongqing, Guangdong, spring maize, cotton, winter wheat and summer corn, peanut, rice, rape and other 17 kinds of field crops. Test results for a wide range of field. Zinc humic acid urea and common urea in the same amount of the case, the average yield of 9.6% crops.
