1. Strengthen the management of fertilizers and waters, and increase the availability of available nitrogen fertilizers according to the degree of phytotoxicity, and increase the number of irrigations at the same time to ensure adequate water and fertilizer supply. 2, increase the temperature inside the shed. When phytotoxicity occurs, the temperature of the shed is increased to 30°C during the day to promote the growth of seedlings, and the original low temperature can be maintained at night to ensure that female flowers continue to differentiate. 3, spraying gibberellin, cucumber grow up to 4 leaves 1 heart when treated with ethephon, the concentration of greater than 200ppm will occur when the phytotoxicity, which can be used 20-50ppm gibberellin solution spray.

The gibberellin currently on the market is a bagged crystal, which should be dissolved with alcohol or liquor prior to application and then formulated in the required concentration. 2, to spray early after the emergence of symptoms of drug injury, otherwise the effect is not good. 3, spraying the first time after the first spray for a second time, about 15 days can all return to normal. When the water supply is insufficient, and the amount of fertilizer is not enough, the cucumber's loin fruit will appear. After the cucumber is pollinated, the supply of nutrients in the plants is insufficient, dry matter accumulation is less, and it is easy to form bee loincloths. Prevention and control measures to strengthen nutrition, especially during the melon period to increase fertilizer and water supply, to ensure adequate accumulation of nutrients.
