Scientists from the United States have shown that carbon dioxide gas fertilizers are most effective when they are used during vigorous growth and maturity of crops. Spraying carbon dioxide gas fertilizer during these two periods can increase vegetable yield by 90%, rice production by 70%, and soybean production by 60%. At present, the commonly used methods for the use of carbon dioxide gas mainly use combustion and chemical reaction methods. These two methods are relatively simple to operate and can be directly burned, hung on trees, or buried in soil, but they should also be properly observed during use. How to use it.
First, it is used when the crop grows vigorously and maturely, and at the same time, it enhances fertilizer and water management and promotes coordinated growth of the plants;
Second, try to use sunny and windless weather. Generally, use it in the early spring to clear the straw half an hour later, and use it to close the greenhouse to prevent gas spillage.
Third, if you choose to use the combustion method to produce gas fertilizer, you should ensure that the open flame is fully burned to prevent the production of harmful gases such as carbon monoxide;
Fourth, pay attention to the use of carbon dioxide gas fertilizer. When gas and fertilizer are used, not as much as possible. If the amount is too much, it will not only promote the growth of the plant, but also cause some waste and increase production costs.
