10. Features

Ascorbic acid is widely distributed in the fruits of plants as a vitamin-type growth substance. Ascorbic acid participates in redox in electron transport systems in plants and promotes plant metabolism. Mixed with indolebutyric acid has a better effect on the induction of rooting than the single use. It also has the effect of capturing free radicals in the body and improving the ability of tomatoes to resist gray mold. In addition, it can be used as a rooting agent for marigold, melamine Powdercosmos, and kidney beans to increase the yield of tobacco leaves.

11. Using technology

(1) Promote rooting

Marigold, cosmos, and kidney beans are treated with ascorbic acid 30mg/L+butyric acid 30mg/L, which can significantly promote the rooting effect of cuttings.

(2) Disease resistance

Wheat seedling stage and booting stage can be sprayed with 30mg/L liquid, which can enhance disease resistance and increase yield.

Tomatoes can be sprayed on tomato fruits with 20~30mg/L liquid to improve the ability to resist gray mold.

Tobacco is sprayed with 125mg/L of liquid medicine to resist mosaic virus disease.

(3) Extend flowering and preservation

Gerbera soaks the fresh cut flower branches with 50mg/L liquid, which can increase the flower stems, prolong the flowering period and achieve preservation.

(4) Improve quality and increase production

Spraying with 30mg/L of liquid in the seedling stage can increase the yield.

The tea tree is sprayed with 20~30mg/L liquid, which can improve the quality of tea and increase the yield.

Tobacco is sprayed evenly with a concentration of 30mg/L, which can regulate growth and increase yield.

The 30-40mg/L liquid leaf spray can be used to increase the yield during the growth period of the pepper.

The use of 20~30mg/L liquid leaf spray on the growth period of mandarin orange can improve quality and increase yield.

12. Notes

(1) The ascorbic acid aqueous solution is acidic, and is quickly oxidized to deoxyascorbic acid upon contact with air.

(2) Light yellow after long storage time. (Yuege Fertilizer Network comprehensive finishing, please indicate the source, please contact 13203809264 for details)
