1, the seed melons are harvested at the end of 1 1 month and placed at 5℃ ~ 7℃. You can keep the whole melon in a jar or sand in a warm place, covered with coal ash and covered with straw to keep warm and prevent freezing for the winter.

2. Germination time: Take out the seed melons at the end of the second year 1 month, wrap them in plastic bags one by one, and move them to a warm room or a hot kang to germinate. The temperature is15 ~ 20℃. The temperature of accelerating germination should not be too high. If the temperature is too high, the bud will be faster, but the bud will be fine and not strong.

3. Isolation fingered citron is a monoecious cross-pollinated plant, and attention should be paid to isolating varieties (strains) during seed cultivation. The commonly used methods are regional isolation method and manual bagging isolation method.

4. When the regional isolation method is used for large-scale seed reservation, the planting distance between varieties should be at least 1000 meters apart, and it can be shortened to about 500 meters if there are natural isolation barriers such as mountains.

5. When a small amount of seeds are reserved by artificial isolation method, paper bags can be put on before the male and female flowers open1~ 2 days, or the petals can be clamped with fuses and small plastics, and the newly opened male flower pollen can be coated on the stigma of the female flowers during pollination.

6, then put back the paper bag or clamp the petals to prevent insects from pollinating. Artificial pollination should be carried out from 6: 00 am to 8: 00 am.

7. Harvesting seed melons can only be harvested when they reach physiological maturity, that is, the skin changes from green to yellowish, or from white to yellowish white, and the skin surface is smooth and hard, with thorns and thorns, and the hand feels prickly.
