Study on the Application Effect of Alginate Oligosaccharide in Agriculture

Alginate Oligosaccharide is an oligosaccharide derived from the degradation of sodium alginate. It has a low molecular weight and is easily absorbed in plants. It can regulate crop growth, increase crop yield and quality, and enhance plant resistance to pathogenic bacteria and stress. Fertilizers, pesticides, auxiliaries, etc. play a role in production. In agricultural production, Alginate Oligosaccharide can be developed into a safe and pollution-free green organic fertilizer, which plays a role in increasing the production and quality of traditional fertilizers. At the same time, it also supplements the deficiencies of traditional fertilizers and artificial synthetic plant regulators, which is conducive to improving the safety of my country’s agricultural products. protect environment.

The experiment studied the effects of Alginate Oligosaccharide samples ADO1, ADO2, ADO3, ADO4, ADO5, ADO6 on the budding rate, bud length and root length of rice, Chinese cabbage, amaranth, radish, cucumber and watermelon. The concentration of Alginate Oligosaccharide samples were all set to 100ppm, and CK was a clear water control. There were 7 treatments. Soaking time of rice and watermelon was 24 hours, soaking time of Chinese cabbage, amaranth and radish was 10 hours, and soaking time of cucumber was 12 hours. Germination test.

The experimental results show that: Alginate Oligosaccharide can increase the germination rate of crop seeds, and promote seed rooting, and the effect is significant. Among them, ADO6 has the best effect. In terms of the effect of promoting root growth, radish has the highest increase of 86.3%, followed by cabbage heart and amaranth. , Watermelon, cucumber, rice, the increase was 19.1%, 17.4%, 14%, 12% and 6.96% respectively. In terms of the effect of promoting bud growth, watermelon had the highest increase rate of 24.6%, followed by amaranth, cucumber, radish, rice, and Chinese cabbage, with increasing rates of 23.5%, 20.5%, 15.6%, 6.9% and 0.6%, respectively.
