Weathered Coal Humic Acid, Sulfonated, And The Development Of New Rice Sturdy - Seeding Agent

The seedlings growth is the foundation of high yields of rice growth, butthe biggest problems of seedlings growth is damping off disease of the rice.For this reason the author researches a new type sulphonated humic acidgrowth promoter of the rice shoots. This growth promoter is a secular releasemultifunctional fertilizer which contains both organic and inorganicsubstances. It consists of some of sulphonated humic acids andmicroelements as well as nitrogen, phosphor and potassium. It is a new typerice shoots growth promoter assembled disease prevented agent, disinfector,soil PH adjuster, seedling nutrition and chemical controller of plants. Thefield experiment shows that after employing this growth promoter the riceshoots is robuster , the seeding age is more flexible, the root fasten moreflourishing, leaf age develop faster, and the tiller ability is better.
