Although the autumn is over, it is still the time when the temperature is the highest, and the plants grow fast. At this time, the summer cucumber growth period is still under the high temperature and strong light environment conditions, in order to make it high quality and high yield, the field water and fertilizer management should be strengthened.
The summer cucumber grows rapidly and aging is fast. In addition to applying the base fertilizer, it is necessary to reapply the top dressing, especially the application of phosphorus and potassium fertilizer, in order to make the melon grow vigorously, avoiding prolonged and premature aging. After entering the melon period, watering and rainfall are more, and soil nutrients are easily lost. Therefore, more fertilizer should be applied and watering should be done frequently. The watering time should be selected in the evening or in the morning. It is not advisable to water at noon.
In the case of high temperature and dry weather, watering once every 1-2 days, 20 kg of urea or high-nitrogen compound fertilizer (26-0-4) per acre. In case of rain or heavy rain, drain and prevent flooding. After the hot and heavy rain, it is necessary to timely cool the well water. In order to prolong the melon period and increase the yield, the surface can be sprayed with 100 kg of potassium dihydrogen phosphate and 50 kg of water per acre, sprayed once every 3 to 5 days, or sprayed with multi-component organic fertilizer on the foliar surface. 500 times, spray the leaves 3 times.
