Summary of the application effects of potassium fulvic acid from mineral sources in the observation area on wheat
3. Promote crops to both “increase income” and “saving expenditure”, and improve drought resistance.
The root system of crops is strong and developed, which improves the vitality of the root system, enhances the absorption capacity of the root system for water and nutrients, and plays an “open source” role; after the mineral source potassium fulvicate is sprayed on the leaves of crops, the stomata on the leaves shrink or close, Transpiration is reduced and water consumption is reduced, which plays a “throttling” role. Potassium fulvicate, a mineral source, promotes crops to both “increase income” and reduce expenditure. The moisture content of crop leaves increases, the water potential of the plants increases significantly, and the dry tips of the leaves are significantly reduced, making the physiological status of the crops strong and vigorous.
4. Enhance the stress resistance of crops
Lodging resistance: The lodging rate of wheat after applying potassium fulvic acid from mineral sources is only 1.4‰, and most of the plants are tilted at 45 degrees; the lodging rate of wheat without application is 8.8‰, and most of the plants are lying flat.
Resistance to diseases and pests: The incidence rate of root disease (seedling bolting) of wheat plants that have been treated with potassium fulvic acid from mineral sources is 0.98%, and the damage caused by midges and aphids is negligible. The incidence rate of root diseases of wheat plants that have not been applied is as high as 8.2%, and the harm caused by aphids, especially midges, is considerable. Serious, resulting in a serious reduction in wheat production last year.
Cold resistance: After the late spring cold, a small part of the seedlings of wheat treated with mineral potassium fulvicate will turn red and return to life after a few days; most of the wheat seedlings that have not been treated with potassium fulvicate will turn red as a whole and become wilted, at least ten days later. Only then did it gradually regain its vitality.
