The delay of the greenhouse delaying the irrigation of the cucumber before the melon should be controlled mainly, less irrigation or irrigation of small water, and reduce the amount of nitrogen fertilizer, appropriate application of phosphorus, potassium fertilizer and 0.2% potassium dihydrogen phosphate root dressing. The early temperature is high, cucumber grows fast, and only 40-45 days from sowing to picking roots. Before the insertion rack, 1 topdressing can be carried out, and 500 kilos of human urine or 300 kilos of dried manure can be applied and put into the rack after irrigation. After entering the melon period, water and fertilizer should be enough to pour 1 water every 4 or 5 days. After top dressing from the rack to mid-October, it is usually top dressing 2 or 3 times. In the single-slope greenhouse, cucumbers can be cultivated for a long time, and they can be top-dressed again in late October or early November. Top dressing should grasp the high temperature in the early period, and cool the quick-acting fertilizer, no more than 20 kg of ammonium sulfate per acre will not only supplement the fertilizer but also reduce the ground temperature. When the temperature is low in the middle and later periods, it should be watered once every 7-8 days. The top dressing should be applied with decomposed organic fertilizer, which will help increase the ground temperature, and the fertilizer effect will last for a long period of time. Once the dosage is 500-750 kilograms per mu, it will be flushed with water. . In addition, in the early stage can also be combined with spraying, spraying 0.3% of urea and 0.2% of potassium dihydrogen phosphate, foliar fertilizer. Continuous rain, weak light, and low-temperature facilitation after the melon, can be sprayed with 0.1% boric acid solution once.
