High-yield cultivation technology of milk cucumber
Milk cucumber is a traditional processed vegetable variety. It grows about 10,000 mu per year. It is named because of its small melon color and bright yellow skin color. After full-shape processing, the color is bright and the meat is crisp, which is always the top grade in processed vegetables. The market prospect is good. . 1 Characteristics: Medium plant growth, less branching, main vine cultivars, flower clusters, 2-3 flowers per section, growth period 60-65 days, general merchandise melon short cylindrical, length 8-10cm, diameter 1.5 ~ 2.0cm, melon-shaped straight, less tumor thorn, is more sensitive to light and temperature, low temperature or light is easy to produce deformed melon. 2 Cultivating Techniques 2.1 Suitable sowing and cultivating cultivation of strong cucumbers in the Yangtze River Basin Due to the influence of the plum rain, it is generally necessary to consider the harvest period to avoid the Meiyu period as far as possible, so as to reduce the disease, improve the quality, and expose the plants to the open season. According to many years of practice, the sowing period should be at the end of March and early April. Generally, nutrients or nutrients are used to grow seedlings. Nutrient soil can be used to add 20% of decomposed organic manure and 1 part of imported compound fertilizer to the soil. 7cm or so, after the actual shooting, use a knife to cut into 8cm square nutrient soil, net 2kg per 667m2 with 400 times Manson Mn-Zn solution, to prevent and control underground pests and diseases, use 500 times chlorothalonil before sowing The solution soaked for 15 minutes, washed, soaked for 4 to 6 hours, and then germination. Use greenhouses and small arch shed nursery or small arch shelter seedlings, after sowing to cover the film to maintain the humidity, seedling temperature 25 ~ 30 °C, usually controlled at 22 ~ 25 °C, to strengthen light and ventilation management, middle seedlings 4 leaf stage colonization, seedling age In 25 to 30 days, the seedlings were grown at low temperature for 3 to 5 days before planting. 2.2 Reasonable crop rotation, sufficient base fertilizer to choose dry land rotation for more than 3 years, paddy and dry land for more than 2 years, soil fertility in the upper, irrigation and better irrigation conditions. Combine soil preparation with 2000-2500kg of organic fertilizer and compound fertilizer of 50kg per 667m2, deep trench sorghum, 1.3m wide (with groove), 30cm wide and 25cm deep. 2.3 Proper close planting, timely use of growth regulators to select good weather, plant 2 rows per plant, plant spacing 35 cm, plant 3300 plants per 667 square meters, applying superphosphate 40 kg per 667 square meter when planting, planting and regenerating seedlings after 5 Spray 40% ethephon 100mg/kg before and after flower bud differentiation to promote the formation of female flowers, spray once every 4 to 5 days, and pay attention to keep pollination when spraying, generally leave 2 lines for pollination In order to prevent poor pollination and produce melon. 2.4 Strengthen fertilizer and water management After the milk cucumbers are put on shelves (sheds), fertilizers must be top-dressed in time. The milk cucumber is not tolerant to fat, and topdressing should be applied frequently; urea is the main form in the early stage of growth, and it is usually applied 1 to 2 times after easing the seedlings, applying urea 5 to 10 kg per 667 square meters at a time to accelerate the growth of seedlings. Timely application of a compound fertilizer, 30kg per 667 square meters, into the results of the peak period, the general application of a compound fertilizer about 7 days, each application of compound fertilizer 15 ~ 20kg, in order to ensure continuous ability to prevent premature aging. Manganese high 1.8 ~ 2.0m topping; enter the results of the period, we must give water to ensure that the melon field to keep moist, in case of continued drought, should be shallow ditch irrigation to meet the fruit expansion needs, improve production and quality. 2.5 Strengthen pest and disease control The main diseases of milk cucumber are mainly wilt disease, downy mildew disease and epidemic disease. The incidence of milk cucumber varies greatly from year to year. The dependence on chemical control is often not very good. Therefore, field management must be strengthened. Taking agricultural comprehensive prevention and control as the main method, applying rotation, applying organic fertilizer, deep ravines, reasonable density, strengthening ventilation, and avoiding rainy days, can play a good effect. Fusarium wilt can be treated with chlorothalonil, carbendazim, or withered root to prevent root canker; downy mildew can be treated with chlorothalonil or metalaxyl; the disease can be treated with Du Gangkelu. 2.6 Time-harvesting fruits can be harvested in about 10 days after flowering, and the head melons and two melons must be harvested in time. After entering the full fruit period, they will be picked once in the morning and in the evening to control the melon type. Generally there are 18 to 22 articles per 500g. , Timely classification and listing after harvest.
