Summer cucumber fertilizer water management measures

Cucumbers are fertile, and cucumbers need more nitrogen and potassium in the fruiting stage. Therefore, after the first time, the melons should be topdressed once, and 20 kg of potassium sulfate compound fertilizer per acre is applied. After entering the harvest period, you can ditch in the middle of the sputum, apply 15 kg of potassium sulphate compound fertilizer per acre, and cover the soil after application. In the later stage, combined with spraying, root dressing can be carried out, such as spraying potassium dihydrogen phosphate, magnesium sulfate, boron and other trace element fertilizers or 1% urea solution to promote cucumber growth. If the plants are robust and vigorous, the amount of topdressing should be appropriately reduced. If the growth of the plants is weak, the amount of fertilizer and the number of topdressing should be increased.

Water management Summer cucumber seedlings due to more rainfall, air humidity and soil moisture are larger, generally can not drench water; in case of high temperature hot weather, in order to reduce the temperature, water can be properly washed to supplement the loss of water due to leaf transpiration. With the growth of the stems and leaves of the plants, it is necessary to meet the needs of stem and leaf growth and transpiration of the leaves in the flowering stage, and to ensure the water requirement of the flowering results of the plants. Therefore, in the sunny or dry places, the semi-ditch water should be kept during the daytime. Drain at night, spray water on the surface in the evening, spray water in the morning or evening if necessary to reduce the temperature. After the rain, it is necessary to eliminate the accumulated water in the field, water the well and lower the ground temperature.
