After 30-35 days of seedling management, seedlings with 3-4 true leaves can be cultivated for colonization.
Apply the base fertilizer before planting. Acre of high-quality farmyard manure 3000-5000 kg, can also be applied to horse manure, sheep manure and so on.
After the whole land is completed, the ridges with a distance of 60-65 cm will be planted at a distance of 40-50 cm, and 2000-2500 plants per acre will be planted. It can also be made into a 1.3-meter-wide flat raft, with two rows per raft.
When planting the seedlings, sit on the water planting. After the water seeps, seal and fix the melons.
The planting safety period is above 13 °C, and the nighttime temperature is not lower than 10 °C.
After slow seedlings should be topdressed (applying 150-200 kg of cake fertilizer, or 50-60 kg of ternary compound fertilizer), and pouring "revitalizing water", but because of the low ground temperature, it is not appropriate to water too much. After that, the soil should be ploughed in time, no water and fertilizer should be applied, and the first melon should be watered until it reaches 10-12 cm. After the melon is dried, it is usually watered once every 5-7 days to keep the topsoil moist, and the rainy season needs to be drained.
When the melon is in the water, the fertilizer is applied 2-3 times. Each application of manure is 1000-1500 kg/mu, or ammonium carbonate 10-15 kg/mu.
Pay attention to the management of water and fertilizer. In the seedling stage or the first female flower, the water and fertilizer will be too long. If the water and fertilizer are not kept up, the yield will decrease. In addition, excessive fruit retention in the early stage may cause poor development of the pupa and affect the total yield.
For early maturity and high yield, artificial pollination should also be carried out (especially when there is no insect pollination). Every day from 6-8 am, the male flowers that are being opened are taken down, the corolla is peeled off, the stamens are exposed, and the female flower stigma is applied several times.
If you need to keep the seeds, you should generally select the melons that are later knotted, otherwise the yield will be affected; the plants that are specially kept will not be subject to this restriction.
