Convolvulus is commonly cultivated in all parts of the province. It is the main greenery of summer and autumn. It has a high temperature and humidity environment. It has strong heat resistance and is not tolerant of frost. In case of frost, the stems and leaves will die, and the optimum temperature for growth is 25-30°C, 10°C. The following growth stagnation, so the winter should use plastic greenhouses for off-season cultivation. The varieties suitable for planting in our province include big chicken yellow, big bone blue, flag leaves, silk worms, big chicken blue and so on. The cultivation of greenhouses can basically be produced in an annual and annual supply. In order to obtain higher economic benefits, they should be planted from October to December and from December to March of the following year. The water spinach grows fast, has strong branching ability, and needs more fertilizer. It should apply enough basic fertilizer, generally apply 1500-2000 kg of decomposed organic fertilizer per acre, 100 kg of plant ash, and fully mix with the soil to form a height of 20 cm. 130-150 centimeters (including ditch). The seed coat of the water spinach seed is thick and hard. If direct sowing will be caused by low temperature and slow germination, in case of a long period of low temperature and rainy weather, it will cause the seeds to rot, so it is appropriate to carry out germination, can be soaked in warm water of about 30 °C 18-20 Hours, then germinate in a pregermination box placed in a sand cloth at 30°C, and when the seeds are 50%-60% white, the seeds can be sowed. Convolvulus can be sowed or drilled. The amount of seed per acre is 15-20 kilograms. After sowing, it is covered with fine soil about 1 centimeter thick. Drilling can be done horizontally on the surface of a 2-3 centimeter deep shallow ditch with 15 cm of groove distance. , And then spread the seeds evenly in the ditch, and then covered with fine soil, and then cover the surface with a shading net, and then drench water, can be opened after the emergence of shading nets. 1, temperature and humidity management In winter cultivation of greenhouse vegetables, low temperature, high humidity, and a long period of low temperature and rainy weather is extremely unfavorable to the growth of the thermophilic water spinach. Therefore, it is the key to anti-season cultivation to keep warm and prevent cold. After sowing, it is necessary to seal the greenhouse in time to ensure that the temperature in the greenhouse is higher than 10°C. Otherwise, it will cause freezing damage. At the same time, when there is sufficient sunshine and a high temperature, ventilation and dehumidification should be intensified to prevent the temperature in the greenhouse from exceeding 35°C. To prevent plant diseases, in order to maintain the vigorous growth of plants, increase production. The relative air temperature in the greenhouse may reach 100% in high humidity and rainy days. At this time, the membranes at both ends or around the greenhouse must be opened in time to allow ventilation. 2. Fertilizer and water management The spinach is a crop that is harvested many times. Therefore, in addition to applying base fertilizer, it is necessary to carry out multiple stages of top dressing in order to obtain high yield. The seedling stage can use 10% to 15% of diluted human fecal urine, and the amount of mu is 1,000. - 1500 kilograms, when the seedlings have 3-4 true leaves, 15-20 kg of compound fertilizer and 2-4 kg of urea are used in combination, and 5-8 kilograms of compound fertilizer (acres) are used for each harvest in the collection period. top dressing. Convolvulus requires large amounts of water and should be often watered to keep the soil moist. The main diseases are seedling damping-off and stalk rot, which are caused by low temperature and high relative humidity. The occurrence of diseases can be reduced through dehumidification. It can be used 700 times or 500 times spray control. . The main pests are crickets and red spiders, which can be sprayed with 1000 times or 1500 times the amount of grams of chlorsulfuron. Usually 35-45 days after sowing, when the water spinach plants grow to 35 cm high, they should be timely harvested.
