Gherkin is an annual creeper of the Cucurbitaceae. This type of melon has a length of 14-18 cm, a diameter of about 3 cm, and a weight of 100 g. The epidermis is soft, smooth, glorious, crisp, and rich in melons. The economic benefits are quite high. Most of the Dutch cucumbers are females, which are important for greenhouse cultivation. Unlike most open-field cultivars, fruit development can be achieved without pollination and fertilization, and intact seeds do not form. The fruit maturity is consistent and early yields are high. The characteristics of this type of melon are: melons, 1 melon, 1 melon and 1 melon. If properly managed, the output of a single 667 square meters (mu) can be more than 10 tons. One year can be planted 2-3 茬. First, nursery Cucumber seeds are expensive and can be sown with trays or nutritious grains when growing seedlings. The planting forest has a high temperature request, and the germination temperature is 24°C-26°C. Generally, it will emerge in 4 days. After emergence, keep 23°C-25°C during the day and 16°C-18°C during the night. Roots are afraid of phlegm, hi temperature and cold, aerobic breathing lush. Must use a well-ventilated, heat preservation, fertilizer conservation, water seepage, moisturizing ability of the matrix, such as peat, vermiculite, perlite, cocoa peat and so on. Second, planting Gherkin has larger leaves, early fruiting period, sustainable fruiting, but the root system can receive weak, so before the planting to exquisite land preparation, a large number of application of organic fertilizer, 667 square meters of cooked livestock manure more than 5,000 kilograms, Add some compound fertilizer. Do small stilts, wide 1 ~ 1.2 meters. The seedling colonization scale is 2 to 4 true leaves, and the seedling age is 25 days, and the density is 2,500/667 square meters. Planting seedlings immediately after planting will facilitate the development of the root system. Third, field management 1. After the fertilization and water planting, a small sapling of water was replenished 3 to 4 days after planting, and the seedlings were increased. After easing the seedling water and then watering, it is necessary to use fertilizer for each fertilizer, and apply 10 kg of urea per 667 square meters, pouring it once every 5 to 7 days. During the melon period, 0.2% to 0.3% of potassium dihydrogen phosphate was sprayed once a week. The air humidity is kept at 80%. 2. The temperature is planted within 1 week during the day and maintained at 25°C-30°C, 18°C-20°C at night, and no more than 35°C. After the seedlings are slowly reduced, the temperature is 22°C to 25°C during the day and 16°C to 18°C ​​at night. 3. Illumination Dutch cucumbers are resistant to weak light and can produce higher yields in the winter under low light conditions. In the summer when there is high temperature and strong light, shade nets must be covered. 4. Carbon dioxide fertilization, if possible, should be properly supplemented with carbon dioxide gas fertilizer so that the indoor carbon dioxide concentration reaches 750 mg/kg, and cucumber production will increase by 20%.
