A plastic bag with a diameter of 18 ~ 20cm and a length of 25cm contains culture soil with a relative humidity of about 75%. Small holes with a diameter of 0.5cm are left at every angle under the bag, so that accumulated water can seep out. First, fill a part of the culture soil in the battery, then plant seeds that accelerate germination up and down, and cover the hands with soil to form a high mound in the center of the battery. Do not water, concentrate in greenhouse or plastic shed, and cover with plastic film to keep moisture. The temperature of plastic greenhouse (greenhouse) and plastic greenhouse (greenhouse) is controlled at 15 ~ 20, and the seedlings grow healthily. Remove the plastic film after catching the seedlings. Don't draw water from the melon bag into the plastic film. Clean the plastic film, moisten the soil, and don't water it in a hurry. During the day, the grass on the film can uncover chestnuts, and cantaloupe can see enough light.

As the temperature rises, the growth of cucumber seedlings will accelerate, so a small amount of water can be properly poured, and flooding is strictly prohibited. Otherwise it will cause cucumber rot. Waiting for the melon seedlings to form a large number of roots, the water supply management can be normal because the biological clock pulse is invalid or the biological clock pulse has passed the "rotten mother" period. During seedling raising, temperature and water management are the main measures. Miao people's physical weakness is caused by low temperature, so the temperature can be raised appropriately. If the melon seedlings are long, you can leave 4-6 leaves to pick the core, and leave 2-3 leaves after the lateral buds come out. If you find saplings with rotten seeds earlier, you can grab them with a well-rooted hand, gently remove the rotten melons and fill them with wet culture soil to cultivate good saplings. 0.3%~0.5% urea solution can be sprayed when melon seedlings are yellow and thin.

Take out the embryo and cultivate the seedlings with culture soil. The plastic bag for seedling cultivation is 20 cm long and has several water leakage holes at the bottom. Before sowing, the bag can be filled with about 10 cm of culture soil. There are two ways to sow seeds. One is to put the germinated embryo horizontally, with the bud facing upwards and the cotyledon covering 3 ~ 4 cm. A single germinated embryo can increase dew by 1 ~ 2 cm in soil. The second is to place the embryo vertically so that one end of the root is facing down and the other end is facing up. The thickness of composite soil does not expose cotyledons, and the soil thickness is about 5 cm. Fold the plastic bag mouth after sowing, in order to keep warm and moist, you don't need to water it for a long time. Plastic bags after sowing can be placed in greenhouses or other protective facilities in winter. In the early stage, the seedbed should be covered with electric hot wire to heat up, and in the evening, it should be covered with bitter heat preservation and temperature management, but the water should be earlier.

Bergamot is no stranger to friends in the south, but it is a little deaf to friends in the north. Papaya is a perennial vine of Cucurbitaceae, native to Mexico, Central America and other regions, and mostly planted in southern China. The shape of bergamot looks like folded hands, so it has the name of watermelon bergamot, which contains a certain auspicious meaning. Bergamot tastes crisp and can be eaten raw. The tender stems and underground stems of bergamot can also be eaten. Moreover, bergamot is a nutritious vegetable with low fat and sodium, which is unavailable.
