Reasonable use of Zenggualing When planting over-summer cucumbers, when cucumber seedlings grow to 3 to 4 leaves, spray Zenggualing or Ethephon to promote female flower differentiation, but you must master the concentration. According to the variety characteristics, plant growth and water and fertilizer conditions in the shed, the appropriate spray concentration and dosage should be selected to avoid the occurrence of pesticide damage and affect the growth at the seedling stage. When spraying Zenggualing, just spray the plant growth point. After spraying, do not immediately water and spray other plant growth regulators, otherwise it will easily affect the efficacy. Reasonable temperature control At this stage, the temperature in the shed is high, and the temperature in the shed is difficult to reduce, which causes the cucumber to consume intensely at night, accumulate nutrients, and inhibit the reproductive growth. The cucumber flower buds are poorly differentiated, the female flowers are few, and the fruit formation ability is poor. During the day, cooling should be done by means of large ventilation, and a cooling agent should be sprayed on the shed film. Strict Guardian The temperature in summer is high, and watering is diligent, which is not conducive to rooting, and it is very important to control water and squat seedlings in the early stage. Plant growth to 7 to 10 leaves is a critical period of water control. At this time, the plant grows vigorously. If no measures are taken, the plant stems grow rapidly, affecting fruit setting. If obvious long-term symptoms such as long internodes and large and thin leaves appear again in the late growth stage of the plant, the drugs such as Zuxin and Chloride can be sprayed to control prosperity.
