1, seed soaking: after the varieties are selected, they are screened. Soak the seeds in warm soup with 55℃ water 1 min, then cool to 25℃ and accelerate germination. When the seeds germinate and appear, sow them quickly.

2. Seedling raising: you can choose a 65-hole black seedling raising tray and plant it in the field at the seedling age of 3-5 leaves.

3. Fertilization: the base fertilizer is fully applied at one time, and the furrow is 30cm away from the plant, and 50- 100kg of potassium sulfate compound fertilizer or 2-3 cubic meters of decomposed livestock manure is applied per mu.

4. Medication: 2-4 kilograms of trichlorfon, phoxim or abamectin are sprayed per mu to control underground pests, nematodes or soil-borne diseases; Spraying phytosanitary and protective fungicides on the leaves once every 10 days, a total of 1 time.

5. Watering: Water less at ordinary times, seize the key period, such as watering swollen melons, and topdressing the quick-acting compound fertilizer at the same time to ensure that the melons are full of nutrients, and water them in time in case of drought.

6. Management: Select the appropriate pruning and pruning methods according to the variety characteristics. For example, Mixiang 900 can grow naturally without pruning and harrowing.

Origin and evolution:

According to the distribution of wild and cultivated species of melon, it is considered that Guinea in tropical Africa is the primary origin center of melon, which was introduced into the Middle East and Near East, Central Asia (including China and Xinjiang) and India through ancient Egypt. It evolved into a melon in Central Asia.

China is the primary and secondary origin center of thin-skinned melon, which was introduced to Russia from Central Asia in the12-13rd century, to America from Europe in the early16th century, and to Japan from America in the 1960s. The melons introduced into India were further divided into thin-skinned melons, and then introduced into China, Korea and Japan.

North China is the secondary origin center of thin-skinned melon. Some people think that melon has multiple origin centers. West Asia (including Turkmenistan and Transcaucasia in the Soviet Union, Iran, Asia Minor and Arabia) is the primary origin center of melon, while Central Asia (Afghanistan, Tajikistan, Uzbekistan, Turkmenistan and Xinjiang in China) is the secondary origin center of melon. China is the primary and secondary origin center of melon.
