Applications of amino acid fertilizers on main crops

1. Fruit trees
The application of amino acid fertilizer on apple trees can increase the weight of louvers by 21–31.5g, and increase the yield per 667 square meters by 21.6%–30.8%. At the same time, it can significantly improve the quality of apples, that is, the hardness can be increased by 0.02–1.22kg/cm 2, the sugar content can be increased by 0.6%–0.84% and the anthocyanin content can also be increased.

2. Watermelon
Watermelon was sprayed with amino acid liquid fertilizer in the watermelon extension stage, the early stage of flowering and fruit set, and the puffing stage of watermelon, which could increase the yield of watermelon by 444.6kg/667 square meters (15.8%). The percentage of soluble solids increased by 11%, which was 11.3% higher than the control.

3. Wheat
The application of amino acid fertilizer on wheat not only has a certain impact on the vegetative growth of wheat, but also can increase the chlorophyll content of the leaves, enhance the photosynthetic capacity, accelerate the grain filling rate, and increase the grain weight and yield. The test showed that the combined effect of seed dressing and foliar spraying would be better, than foliar spraying, and seed dressing alone had little effect on yield.

4. Greenhouse vegetables
According to the experiments on greenhouse tomatoes, cucumbers, peppers, leeks, and other vegetables, the yield of various vegetables increased by 19%–35.1% compared with the control, and the quality was improved. In addition, it can also control some fungal diseases, such as downy mildew, blight, fusarium wilt, etc. After spraying amino acid fertilizer, it can increase the synthesis of anthocyanin, chlorophyll, and other substances in plants, activate plant function, promote plant photosynthesis, in addition, to enhance plant nitrogen fixation, and strengthen vegetative growth to increase yield. If it is added with seed dressing, it can also promote root development and enhance the cold and drought resistance of plants.
