Summer temperatures are high and plants grow fast. The growth period of cucumber in summer is just under the high temperature and strong light conditions. In order to make it high quality and high yield, the water and fertilizer management in the field should be strengthened.
Throughout the summer, the cucumber grows rapidly and grows quickly. In addition to applying the base fertilizer, it is necessary to replenish the topdressing fertilizer, especially by adding phosphorus and potassium fertilizers, in order to make the pod grow vigorously and prevent premature growth and premature aging. After entering the melon period, there will be more watering and rainfall, and the soil nutrients will be easily lost. Therefore, more fertilizer and groundwater should be used. The watering time should be selected in the evening or in the morning and it should not be watered at noon.
In high-temperature and dry weather, watering is performed once every 1~2 days, and topdressing urea or high-nitrogen compound fertilizer (26-0-4) 20 kg per acre during the watering interval. In case of rain or heavy rain, it is necessary to drain water and prevent flooding. After the hot and rainy days, it is necessary to timely cool the well water. In order to prolong the melon period and increase the yield, the use of potassium dihydrogen phosphate 100g/water 50kg per acre for foliar spray, spray once every 3 to 5 days, can also be foliar spray multiple compound organic fertilizer, dilution 500 times, spray 3 times.
