The cucumber is a common Chinese melon vegetable, belonging to the Cucurbitaceae, pumpkin family, with clear heart heat, moistening the heart and lungs, in addition to thirst, the small intestine, water, swelling, through the lymphatic dissipation and other effects. Cucurbit is native to tropical Asia, India, North Africa, the whole plant is densely covered with soft hairs, with tendrils, can creep to the ground or climb other things to grow, leaves alternate, heart-shaped, serrated edge, usually divided into large gourd and small gourd, the former can be fresh food and the latter purely for ornamental. It likes high temperature, and its fertile temperature is 25 to 28 degrees Celsius, below 15 degrees Celsius or above 35 degrees Celsius will easily lead to poor fertility. Cucurbits can be categorized into seven types according to their fruit type, including kettle cucurbits, ladle cucurbits, long flat cucurbits, gourd cucurbits, dolphin cucurbits, spherical cucurbits, and warty cucurbits. Native to tropical Asia, India, and North Africa.

Soak the seeds in warm water at 40 ℃ for 12 to 24 hours, fish out, wrap in gauze and shake dry, and high on the soaked sweet gourd seeds. With a wooden trough or ordinary pot, pad a layer of sterilized sawdust or sand, and then a layer of gauze, the soaked seeds evenly placed on the gauze, covered with a wrung out new towel, covered with a cover curtain, covered with a quilt germination, and dusted with a new brush broom water 2 times a day. Germination temperature is generally 25 to 28 ℃. Requirements every day to pick up the seeds that have sprouted, placed in a separate pot, placed in a cool place indoors to control the growth of buds.

Sowing seeds in seedbed

1, seedbed preparation. The bottom of the seedbed is padded with 8 to 10 centimeters of horse manure or crushed grass, with a layer of soil on top, stepped on. At the same time with 70% of the 0.3 to 0.6 g / m2 of diclofenac wettable powder disinfection, while buckling the shed. After the seeds are sown, the shed is fastened again on the seedbed.

2, nutrient soil preparation. Choose the soil that has not been used with herbicides such as Pulsatilla and Beansulfuron and sieve it well and mix it with sifted rotted farmyard fertilizer in the ratio of 7:2.

3, bag seeding. Nutritional soil into 10 cm × 15 cm plastic bags, and in the bottom 1/3 of the plastic bag into the 20 ~ 30 grain diammonium as a base fertilizer, full of pier solid, and nutritional bag bottom corner cut or at the bottom of the aperture of 8 ~ 10 mm eye 2 ~ 4 in order to permeability. Sowing time according to the local season shall prevail. With a wooden stick in the middle of the nutrient bag to tie 3 to 4 cm deep eye, will be good germination of the seeds, bud eyes facing down put good, after the soil for a watering.

Seedling bed management

Appropriate watering, not too flooded; control of rodents, pests, available phoxim, trichlorfon mixed with wheat bran (bait) can be; hoeing in a timely manner, foliar fertilizer spraying; in the true leaves to grow to 3 ~ 4 pieces of the beginning of the centering, to prevent futility; seedbed temperature 25 ~ 28 ℃, the night is not less than 15 ℃. General seedling age 35 ~ 40 days, 5 ~ 7 days before planting seedling refining.

Transplanting at the right time

1, digging large holes. Before transplanting dig 20 cm × 20 cm hole, spacing 1.3 ~ 1.6 m, mu to protect seedlings 80 ~ 100 or so, each hole to apply 5 ~ 7.5 kg of farmyard manure and 100 ~ 250 grams of fertilizer (diammonium, potash, magnesium powder ratio of 3:1:1) to do the bottom fertilizer.

2, artificial transplanting. Before transplanting the nutrient bag watered, the seedling transplantation hole, cover the soil, and watered. At the same time cover the film, keyhole put seedlings. You can also choose to transplant double membrane, that is, after transplanting plus cover the arch film.

Field management

1, manual hoeing, timely control of pests and diseases.

2, combined with fertilizer importance of the empty ridge and grass. Use about 1 kg of straw or wheat straw per square meter to prevent grass shortage. In the main vine grows to 50 cm or so, it is best to combine with irrigation, each plant of urea 100 ~ 250 grams, fertilizer is not too close to the main root, to prevent the burning of the root. Do not scatter urea on the leaf surface to prevent leaf burning.

3, down the vine, pinch, pitchfork, artificial pollination. Shun vine, each plant to stay two main vines. The two main vines are horizontally placed on the empty ridge, can be cultivated once directed soil. Pinch, a branch, grow to 3 leaves, start to pinch, watch and pinch adjust the second and third level of branches, main vine pinch after August 23rd. Artificial pollination, the general sweet gourd every morning fork, pinch, 16:00 pm to start pollination, after the summer heat can stop pollination, the general two main vine melon 6 to 8.

Harvesting

Early August began to gradually harvest, that is, the first crop of melons to grow to 7 to 9 kilograms or so, the principle of the first day of harvesting, the next day, first peeled off the melon, and then peeled the melon strips.
