2. Mid-ripe varieties: it takes 100,120 days from sowing to harvest, slightly later from female flower opening to maturity, larger plant type, strong growth, large melon, thick skin, more resistant to transportation and storage, such as Xinong R and so on.

3. Late-maturing varieties: it takes more than 120 days from sowing to harvest, less cultivation, large melon, high yield and resistance to storage and transportation, such as Hongyou 2, Jingfengbao, Fengshou 2, Xinhongbao, Jinhuabao, Qihong watermelon and so on.

Sowing method of watermelon

1. Soaking seeds to promote germination: before sowing watermelon seeds for 2 days, then disinfect the seeds, soak the seeds with 55 ℃ warm water, wash the treated seeds, put them in a thermostat and germinate at 40 ℃ for 6 hours, accelerate germination at a constant temperature of 33 ℃, and sow seeds when the radicle grows to 0.5cm.

2. Prepare the seedling bed: the watermelon seedling bed selects the plot of leeward to the sun, high dryness and convenient management, raising seedlings in greenhouse or greenhouse in early spring, sunshade should be built after autumn, nutrient soil should be loose, free of diseases and insect pests, N, P and K fertilizer should be applied in proportion, slightly sticky.

3. Sowing at the right time: the early-maturing watermelon varieties were sowed from mid-December to late March last year, the middle-maturing varieties were sown from April to June, the autumn was postponed to the middle and late July, the seeds were watered thoroughly one day before sowing, and the seeds were placed flat in a nutrition bowl, 1 grain per bowl, covered with thin film.

4. Temperature management: the temperature in the bed of watermelon was controlled at 28: 35 ℃ in daytime and 20: 25 ℃ at night, 20: 25 ℃ in daytime and 15: 18 ℃ at night after 80% seeds were broken, and 25: 28 ℃ in daytime after the first true leaf appeared. Seedling refinement began one week before transplanting.

5. Water management: watermelon seedlings are generally no longer watered before they are unearthed, watering should be controlled at the cotyledon stage, and the amount of water can be increased after the real leaves are exhibited. In addition, pay attention to uncover the film ventilation to prevent high temperature and humidity. Water supply should be paid attention to during the high temperature drying of autumn watermelon seedlings.

Planting methods of watermelon

1. Selection and fertilization: for watermelon planting, it is appropriate to select sandy loam with deep soil layer, loose soil and convenient drainage and irrigation. the base fertilizer is mainly organic fertilizer and cake fertilizer, supplemented by inorganic fertilizer, which generally accounts for 6070% of the total fertilizer. Nitrogen, phosphorus and potassium are reasonably matched. Micro-fertilizer is applied or sprayed according to the situation.

2. Timely planting: watermelon early-maturing varieties can be colonized when they grow 2 or 3 true leaves in one month, middle-maturing varieties 20-25 days, late-maturing varieties 7-10 days, wide-border planting 2 rows, narrow-border planting 1 row, transplanting while covering film.

3. Pruning and pressing vines: watermelons are generally pruned with three vines, leaving the main vine and two strong lateral vines when the main vine is 8-9 leaves, pressing the vine with soil when the vine grows to 50 cm, and then pressing it again at intervals of 3-4 knots, each vine is pressed for 2-3 times, and the melon vines are arranged evenly.

4. Sitting melon and turning melon: watermelon chooses the 2nd and 3rd female flowers on the main vine or the 1st and 2nd female flowers on lateral vines. Artificial pollination should be used in case of low temperature or cloudy and rainy weather. Turn melon in time after the fruit is fully grown, turn in one direction when turning melon, about 1x3 each time.

5. Water and fertilizer management: when young watermelons grow to the size of eggs, expanded melon fertilizer is applied according to plant growth, generally 45% nitrosulfo or potassium sulfate controlled-release fertilizer is applied to 15,20kg per mu, and water should be irrigated in the early and late night when the temperature is low. At the same time, drain the stagnant water in the field in time after rain.

6. timely harvest: watermelons should be harvested in the morning, long-distance transportation or storage in medium well, and sales in the suburbs at well-done on the same day. Generally, early-maturing varieties are harvested about 30 days after pollination, 35 days for medium-maturing varieties and 40 days for late-maturing varieties.

7. pest control: the main diseases of watermelon are Fusarium wilt, anthrax, virus, powdery mildew, blight, etc., and the main pests are small land tiger, aphid, red spider, Huangshou melon, melon maggot, leaf miner and so on.
