Foliar spray fertilizer. Spraying 0.3% aqueous urea solution in the seedling stage can promote early seedling growth. It can also spray 0.5% ferrous sulfate solution to promote the seedlings and make the leaves dark green. Spraying 0.2% boric acid solution at 7 leaves can preserve flowers and preserve fruit; in the case of a large number of melons, spraying 0.3% potassium dihydrogen phosphate solution and 0.5% urea mixture for fertilizer supplement can increase the yield of melon.
Spray chicken manure. Spraying chicken manure with cucumber can not only supplement the deficiency of nitrogen, phosphorus, potassium and trace elements, but also stimulate the growth and development of crops, promote early maturity and increase drought resistance, cold resistance and disease resistance. According to the test, the chicken feces can be sprayed 3 times in the growth period of cucumber, which can increase the yield by about 15%. The method comprises the following steps: taking 3 kg of dried chicken manure, 50 kg of water, soaking for 5-7 days, and after fully fermenting, the residue is filtered off and sprayed on the surface. Spray on the first cucumber finger when it is thick, 30-40 kg of liquid per acre, spray 10 days at a time, spray in the afternoon or evening.
Artificial assisted pollination. After the flowering of cucumber, artificial-assisted pollination, the male flower of the harvested flower is aimed at the stigma of the female stamen, and gently applied a few times to reduce the phenomenon of cucumber falling off and turning melon, increasing the fruit setting rate and increasing the yield of cucumber.
Artificial emasculation. In the five-day period of the squash, go to the male once, leaving 5% to 10% of the male flowers. The initial interval of the squash can be longer, and the time is 6-7 days. Cucumber emasculation can reduce nutrient consumption, promote plant growth, and increase yield.
Topping. The side vines with weak growth potential are topped after sitting on the melon, and the side vines with strong growth can be used to increase the yield of the melon group.
