The current topdressing method used by growers of bitter melons is to flush with water, which is convenient and can evenly apply the fertilizer to the soil. However, it is not advisable to use topdressing in this manner. The reason is that the number of plants in the bitter gourd species is less, only 200 to 300 plants per acre, and only 3 to 6 plants per row. If the fertilizer is applied along with water, the fertilizer utilization rate will be very low and the waste will be serious.
Therefore, to remind farmers friends: dressing bitter gourd should be changed to concentrated fertilization, such as digging ring groove fertilization, which can greatly improve the utilization of fertilizer. The specific method is to dig a ring groove 20 centimeters inside the bitter gourd plant, the ditch depth is 5 cm, then apply 50 g compound fertilizer or 80 g biological fertilizer per ditch, and water the soil after burying the ditch. It is also possible to dig a half-metre-long strip of furrows 20 centimeters from the inside of the bitter gourd plant, applying the above-mentioned amount of fertilizer to each furrow. The effect is also good. It should be noted that bitter gourd should be watered in time after top dressing so that the absorption effect is better.
