1. A hole with a depth of 5 cm and a diameter of about 4 cm can be drilled on the plastic film for sowing. The vertical distance of each plant is 30 cm to 35 cm, and 3 rows can be planted in each border.
2. After sowing, cover the soil and pour a little water to help slow down the seedlings.
3. When the seedlings grow to a certain degree, it is necessary to pick the vines.
Remove the long beard from the main vine so that the lateral vine can grow better. During the growth of watermelon, a melon vine should be set aside every 2 ~ 3 knots. After selecting, leave two melons on each side vine, and remove all melons with bad shape, deformity and flat size.
Extended data:
grow seedlings
1, prepare a seedbed, and then sow on the seedbed;
2. Build an arched shed with bamboo to ensure that the temperature will not affect the germination of seeds;
3. The seeds will grow seedlings within 3-5 days after sowing;
4. A little ventilation and timely watering can make the seedlings grow faster;
5, when the seedlings grow to 5 cm to 8 cm, they should be bagged for temporary cultivation, and the bags should be filled with nutrient soil;
6. Then transplant the seedlings into a nutrition bowl and put them in a seedbed. This can make the roots of seedlings grow faster, which is convenient for future management and planting. The seedlings can be colonized when they grow to 10cm ~ 15cm.
