Problems solved by technology

Plant growth regulators increase the fruit setting rate by promoting the rapid thickening of the fruit stalk. When using it, the method of smearing the flower stalk and spraying the flower is mainly used. However, due to the difficulty in controlling the concentration, deformed fruit, cracked fruit, and stiff fruit are prone to occur. The flower method is more labor-intensive, so the usage rate is getting lower and lower

The mixed solution of nutrient elements and plant growth regulators is used by plant spraying method, which saves labor, time and high efficiency, but the addition of trace elements and / or pesticides increases the cost, which is difficult for some farmers to accept
