The role of fulvic acid application on wheat

Wheat heading to filling stage. An acre of wheat consumes about 10,000 kilograms of water on average, and consumes 300,000 kilograms in 30 days. Three hundred million kilograms of wheat consumes 30 trillion kilograms or 15 billion tons of water. Many people believe that the water in the wheat field is mainly due to the transpiration of sunshine. In fact, more than 90% of the water is steamed through the leaves. Agricultural chemists in various countries have tried to find a chemical to reduce the transpiration of the foliage.

However, some of the found agents are expensive, have a short duration of action, and some have disadvantages such as pollution and poor photosynthesis, so they are not practical.
It is the Chinese scientists who first discovered that the natural fulvic acid has anti-transpiration effect and made a report at the world conference held in Australia, which has attracted the attention of all countries in the world. fulvic acid is different from the above-mentioned chemical reagents, and the price is low. The action time can reach ten to fifteen days, and it is pollution-free and does not hinder normal photosynthesis. fulvic acid reduces transpiration by 10-15% in ten to fifteen days. Don’t underestimate this number. It says that 100 million mu of wheat will be transpiration of 15 billion tons of water a month, and a 10% reduction is 1.5 billion tons. This is of great significance for wheat to fight drought and harvest.

What is the reason that fulvic acid can reduce water transpiration?
We observed using a high-resolution electron microscope that the water is transpiration from the small pores of the leaf surface. The fulvic acid can reduce the opening of the pores of the leaves, reduce the transpiration of water, and mobilize the absorption of potassium ions by plants. Promote metabolism, promote respiratory intensity, photosynthesis intensity, promote plant enzyme activity, improve crop drought resistance, and thus improve water-saving capacity, and plants’ ability to resist drought, cold, and pests and diseases will increase. When wheat is grouted, it is most afraid of dry hot air. It can be seen that the transpiration of 10,000 jin of water in the first part of the article is normal. When the dry hot air comes, the temperature is high, the air is very dry, and there is wind. The transpiration will be greatly enhanced. The water absorbed by the roots is far from being supplied. In severe cases, the wheat will die and die, not to mention the reduction in production. If you pay attention to the weather forecast, spraying the fulvic acid one to two days before the onset of dry hot air can effectively resist heat and drought. Similarly, spraying fulvic acid one to two days before the cold current can greatly reduce the impact of cold current on crops.
