What is cucumber cucumber? Cucumber female flowers are not open or open after the ovary does not inflate, rapidly shrinking yellow off, known as melon. The phenomena of cucumber and melon that appear in greenhouses are caused by many factors such as environmental conditions, cultivation seasons, and cultivars. Now the solution measures are briefly described as follows: 1. Due to excessively high or low temperatures during the nursery period, water shortage due to drought Insufficient illumination, seedling growth, and other reasons cause the flower buds to be blocked due to the differentiation of flower buds. It can be solved by cultivating cucumber seedlings. Papaya caused by hypothermia at the seedling stage can be remedied by foliar spraying of 1% potassium dihydrogen phosphate + 1% glucose + 1% urea mixture. In order to prevent jujube from causing leggy in the seedling stage, the seedlings can be sprayed with 150-200 mg/kg ethephon solution in 1 leaf 1 heart and 3 leaf 1 heart period to prevent leggy, promote female flowers, and increase yield. 2. Due to the excessive growth of vegetative growth, the melons can be solved by means of coordinated reproductive growth and vegetative growth. Such as delaying top dressing and watering period, controlling the application of nitrogen fertilizer. It has been found that when the plants grow vigorously and cause melons, 100 mg/kg ethephon solution can be sprayed to promote the occurrence of female flowers; when the plant internodes are too long, growth is weak, and there are signs of leggy, 20 mg/kg of chlormeson solution can be sprayed. Suppresses leggy and promotes melon growth. 3. Due to the high temperature during the growth period, drought or lack of fertilizer or nitrogen fertilizer caused by the melon, can be taken to reduce the temperature, timely irrigation, increase the application of phosphorus and potassium fertilizer solution. The production of human fecal urine (500-700 kg/mu) and foliar spray of 0.3% potassium dihydrogen phosphate + 0.5% urea + 1% glucose mixture are often used to overcome the excessive nitrogen fertilizer caused by the melon. 4. Because of the low temperature, cloudy day caused by the melon can be taken: (1) 1% potassium dihydrogen phosphate + 1% glucose + 1% urea mixed foliar spray (mainly used at the seedling stage). (2) Overwintering and picking cucumbers, spraying flowers with 100 mg/kg gibberellin solution during the melon period can promote the growth of the melons and prevent the low temperature of the melons. (3) Spraying small melon with a solution of 500-1000 mg/kg cytokinin 2 to 3 days after flowering of cucumber can accelerate the growth of the melon and prevent the growth of the melon. (4) When 7 cucumber leaves are sprayed, 0.2% boric acid aqueous solution is sprayed to protect the melon. (5) 50 ~ 100 mg / kg gibberellin + 40 mg / kg naphthyl acetate mixture, smear with a brush or smear melon or melon spray with a handheld sprayer, can reduce the melon, and melon strip expansion speed Fast, increase production and increase income. 5. Due to the uncomfortable gas concentration in the shed, the carbs can be treated with greenhouse carbon dioxide fertilization. The carbon dioxide gas fertilizer produced by Henan Xinfeng Technology Development Co., Ltd. has a good effect. 6. Due to the excessive close planting of the melon, can be taken to solve the method of reasonable close planting. (1) The density of early spring cucumbers should be 4000 plants/mu. (2) The density of cucumber after the fall is 5,000 plants/mu. (3) The density of cucumbers used for wintering is 3500-4000 plants/mu. 7. Due to the root melon harvesting is not timely to cause melon, can be timely picking root melon. This kind of situation often occurs on the grower who first cultivated cucumbers. If the melons grow in the field due to the late root picking, they can be compensated by applying human excrement and spraying the phosphorus and potassium fertilizers outside the roots. 8. Pesticides caused by pests and diseases can be solved by strengthening pest control, spraying some plant growth regulators and strengthening fertilizer and water management, improving cucumber disease resistance, and promoting robust growth. Commonly used plant growth regulators on cucumbers are 500-fold greener 95 and 1000-fold plant power 2003. 9. Due to the strong variety of knots, and the nutritional supply can not keep up with the melon, the cultivation of different types of cultivation facilities, the use of suitable cultivars. Generally available in Jinza No.2, Jinza No.4, Jinchun No.3, Jinyou No.1, Jinyou No.2, and Jinlu No.3, and the melons are lighter; Xintai Miqin, Changchun Mimi, etc. There are melons, a lot of melons, and the management of fertilizers and water cannot keep up. When the pests and diseases are serious, they tend to show heavier melons.
