1, sowing
1.1 sowing time Because parents need to sow the wrong time, according to the characteristics of the general father of the general broadcast in advance 5 to 10 days in order to be able to provide sufficient male. Seedling age is generally 30 to 40 days. When planting, seedlings can reach 2 leaves 1 heart to 3 leaves 1 heart. In the south-central part of Hebei Province, the father is usually planted in early February, and the female parent is sowed 5 to 10 days later, and is advanced or delayed according to weather conditions.
1.2 Prepare seedlings for seedlings before use Seedlings for nutrition, 1010 plastic oysters can be used for nutrition. The nutrient soil should use fertile topsoil that has not been grown with melons. Each side of the soil is adulterated with 0.3 cubic meters of ring fertilizer and 1.5~2kg of compound fertilizer. Put the nutritious soil on the bed, squeeze it tightly on the bed, soak the seedlings into the bottom water before sowing, but avoid getting wet.
1.3 Seeding Techniques Seeds of 1 seed germinated per shoot. When sowing, it is necessary to use medicinal soil for “covering under coverâ€. Generally, the thickness of cover soil is 0.8 to 1 cm. After sowing, seedlings are to be covered with a plastic film and a small arch shed so that the temperature inside the shed is kept at 32° C. during the day and not less than 20° C. during the night. After the seeds are removed, the soil is removed.
1.4 After the emergence of seedling management, the temperature is controlled at 25-28°C during the day and 12-15°C at night. After cotyledon flattening, the temperature can be appropriately increased, and the temperature can be increased to 28 to 30°C during the day and 15°C at night. After the melon seedlings have 2 leaves 1 heart or 3 leaves 1 heart, they can be planted.
2, colonization
2.1 Planting time Planting time is generally about mid-March.
2.2 Preparation before planting melon seed production requires a higher amount of fertilizer, to re-applied organic fertilizer, the general application of crude fertilizer per acre at the end of 3 to 4 cubic meters, three yuan compound fertilizer 100kg, the fertilizer deep, after turning the ground leveling Do something fine.
2.3 Planting Techniques Planting techniques are generally used in the planting of sorghum planting. First, sorghum is made with a row spacing of 60 cm, and then a small trench of 15 cm deep is opened in the sorghum to prepare for planting. Female mothers such as single vine pruning mu planting density of 2200, row spacing 60cm, plant spacing 50cm, strains left double melon. Such as double vine pruning can plant 1200 per acre, row spacing is 60cm, plant spacing is 90cm, leaving 3 to 4 melons per plant. The number of paternal parents depends on the number of mothers. The proportion of parents is generally 1:10. During planting, the seedlings are placed in the ditch in accordance with the spacing of the plants. Water is poured along the ditch. After the water infiltrates, the soil is turned into a sorghum and then covered with a plastic film.
2.4 Post-planting management The temperature in the greenhouse before the seedlings should be controlled at 30-33°C, and the new roots should be sprayed. When the new leaf grows, the temperature is lowered, during the day 30°C and at night 15°C. After planting water, it is necessary to draw several times to facilitate conservation.
3, pruning from the planting to pollination before the parents of the melon should be pruned, pruning there are two ways: one is a single vine pruning, the other is a double vine pruning, to be determined by the density. When the single vine pruning, the female vine vines grow 6 vines below the leaf side of the vine can be left to 2 to 3 vegetative branches according to the strength of the seedlings, leaving these lateral branches 2 to 3 leaves topping. The lateral branches from 6 leaves to 11 leaves were all removed. Generally, 12 to 15 leaves of the side vines stay on the melon, pollination, the election to stay next to the two vines on the vine, generally leaving two melons per plant.
When double-vine pruning, the melon seedlings were topped when they were 5 leaves, and each had two strong lateral vines. When the leaves of 8 leaves were selected, the vines on the adjacent two vines were left to stay, and after the pollination, 2 vines were left.
The father of the melon does not squash and grow, the father wants to be early, after the seedlings, the fertilizer can be topped and watered to maintain the growth of the father.
4. Cross pollination Every morning from morning till sunrise, pick the male flower that will be opened immediately and put it into a covered container (such as a lunch box, a tin can, a plastic jar, etc.). Place a clean and moistened container at the bottom of the container. Small towels or shawls, covered with lids placed in a cool place, side by side, so as not to lose the water wilting, or in the afternoon on the male plant will open the male flowers to be bagged the next day, picking the next day Conduct pollination. The mothers who are to be open the next day are fully decapitated and pollinated with the male paternal male flowers. Each male flower can grant 2 female flowers, and then the pollinated female flowers are put on the paper hat. Make a mark. Pollination should be carried out from 6 to 10 o'clock in the morning and from 4 to 7 o'clock in the afternoon, avoiding high temperatures during noon.
The above process requires a one-time completion. When the bag is bagged, the upper hat of the female flower must be firm, and the marked mark must be clearly firm. After the completion of the powder, check the complete flower after pollination. If the leaking sleeve or the flag is completely clear, it must be removed.
After pollination to the melon seat, the temperature in the shed during the day should be maintained at 25 to 30°C, and not less than 16°C at night.
5. After pollination is completed after pollination, the mother plants of Quantian should be re-arranged and the unmarked natural pollinated melons should be completely removed. The mulching film should be removed and the collaterals above the seat of the melon segments should be left with 2 to 3 leaves topping. The main vine grows up to 25 leaves. When the whole field is about 70% of the size of melons like jujube, it can be watered and topdressed. When applying fertilizer, 25kg of urea or 30kg of compound fertilizer can be applied per acre. After 10 days, the water is poured again and the fertilizer is applied as appropriate.
6. Seed-producing melon seed collection technology
6.1 Melon production Melons should be cleaned once in three days before harvesting. It is necessary to go through the tests on a piece by piece basis and remove those unmarked melons. When the harvest is officially conducted, special personnel are responsible for the melon harvesting work. It is necessary to recognize whether there is a pollination flag for each melon and avoid mixing pollinated melons that are not hybridized during the seed collection process.
6.2 After the seeds have been cut, pour the seeds into a cylinder or a bucket. After pouring into clean water to wash, wash the sunken seeds that have been washed clean and dipped into the water.
6.3 Select seed seeds should be selected after basking, and white seeds, broken seeds, and special-shaped seeds should all be selected. Qualified seeds are stored in storage.
