Variety selection
Jiangsu local varieties of strong vitality, high temperature resistance. When the temperature reaches 30 degrees, they do not age ℃ in the summer, the harvest can last until the end of August. You can also choose Fengyan, Cuiyan, Chunyan, Xiyan and Miyan varieties produced by Taiwan Nongyou Company. Late-sown varieties should be heat-resistant, such as Dai Duo Xing.
Sowing at the right time
Summer sowing is around early May, and harvesting is around early July. Cultivating age-appropriate strong seedlings is the basis of high yield of milk cucumber. Seedbed soil should be selected in the soil loose and fertile, no melon on the vegetable garden. Each mu of field nursery needs 0.05 mu seedbed, with 150 grams of seed, 50-100 kg of rotted human manure, 2.5 kg of phosphate fertilizer. Apply a layer of furadan under the bed to control underground pests. The ground is prepared with fine soil, compartmentalized at a width of 1.3 m. On a level base, the seeds are sown with a layer of fine soil to prevent the seeds from being exposed. Nutrient bowls can also be made of paper or film. The prepared nutrient soil can be used to fill the nutrient bowl for sowing seeds, which is covered with a thin layer of soil. It is then covered with plastic film and a small arched shed is built over it. It is covered with grass curtains at night to protect it from the cold and keep it warm. Seedlings emerge 6 to 7 d after sowing. When about 70% of the seeds are broken, remove the flattened plastic film and exercise the seedlings through ventilation. Fertilizer application should be controlled at the seedling stage.
Improving the quality of transplanting
In the field, plots that had not grown melons for three years were selected. Before planting, combined with land reclamation, 1000 kilograms of humus per mu was applied, and sunny days were chosen for transplanting. Nutrient potting seedlings transplanted 10-15 days after the emergence of seedlings (i.e., cotyledon compression), with soil seedlings transplanted within 10 days after the emergence of seedlings. One day before planting, irrigate the nutrient bowl or soil with dilute manure water. After the water on the leaf surface evaporates, spray 600-800 times diluted Manganese Zinc Dyson. Seedlings should be lowered into the ground with fertilizers and medicines, and small seedlings should be transplanted with soil to avoid damaging the root system. Planting density of about 4,000 plants / mu, that is, the width of the bed 1.4 meters, each bed planting two rows, row spacing 60-75 cm, row spacing 20-26 cm.
Build a hut to catch the hearts. When the cucumbers start to grow, build a shed. The shed is in the shape of "herringbone", about 2 meters high, in time to tie the vines and straighten the branches and vines. The main vine grows to about 1.6 meters, and cover, promote the side vine melon, improve yield. Production practice shows that the number of side vine melons is twice the number of main vine melons. Therefore, 2-3 leaves should be left to pick the center.
Tillage and fertilization
In the early growth of milky cucumber, it is necessary to carry out timely tilling and weeding to reduce weed damage and promote root growth. Fertilizer should be controlled early and promoted late, that is, from planting to grape growth without fertilizer. For the weaker growth potential, light application of thin fertilizer can be applied to avoid delaying flowering and fruiting due to excessive plant growth, affecting yield. After spreading, apply 50-100kg of cake fertilizer and 30kg of potash per acre, and open furrows or drill holes. At the beginning of the harvest, fertilizer should be applied after the first harvest, 20 kg of urea per mu, and then every 10 days, the amount of fertilizer gradually increased.
Pest control
The main disease of cucumber is downy mildew. The early stage of the disease can be sprayed with 40% Aluminum Phosphorus Aluminum 250 times liquid and 60% Manganese Zinc 600 times liquid, every 1 week, spray 2 to 3 times. In the middle and late aphid infestation is serious, 100% aphid enemy net can control 2500 ~ 3000 times.
Harvest
Female flowers open 6-10 days later, when the melon is 12 cm long and 2.0-2.5 cm in diameter, fresh fruit can be harvested with a 1 cm stem. Milk cucumber can be harvested one week after flowering. Harvest standard: 44-46 milk cucumbers per kilogram, 10 cm long and 2 cm in diameter. In the early stages of harvest, harvest every 3-4 days. In the middle and late stages, as the temperature rises, the ripening time is accelerated and the harvesting interval is shortened. At the peak, harvest in the morning and evening.
