First of all, before sowing, the seeds should be dried in the sun or soaked in warm soup to kill some larvae, viruses and bacteria attached to the surface of the seeds, thus improving the disease resistance of the seeds themselves and promoting the improvement of yield and quality. Specific methods: soak the seeds in warm water at 55℃ 10- 15 minutes, naturally cool, soak the seeds in clean water for 4-6 hours, and then wash the seeds with clean water.
At this time, farmers after soaking seeds should pay attention. If the seeds are sown in early spring, it is necessary to accelerate germination because of the low temperature of the planting environment after soaking. Wrap the cleaned pumpkin seeds with gauze and keep them moist, place them in a cool environment at 28℃-30℃, and plant them after the seeds are exposed more than half;
If you sow in autumn, the sowing environment requires high requirements, and you can sow directly without germination.
Second, fertilization. Pumpkin with small fruit needs a lot of fertilizer, which is characterized by light before and heavy after. Generally, base fertilizer should be applied, and topdressing should be appropriate according to the growth situation. When the fruit grows to 0.3-0.5kg, it is necessary to strengthen fertilizer and water management and promote fruit expansion. Apply ternary compound fertilizer and potassium chloride 5- 10 kg per mu. Apply fertilizer once at each harvest of melon, and apply it continuously for 3 ~ 4 times.
Finally, the fruit setting rate of small fruit pumpkin is very important. Artificial pollination can be carried out at 7~9 o'clock every day in flowering period to improve the fruit setting rate. Specific methods: Take down the male flowers that opened that day and gently wipe them on the stigma of the female flowers. A male flower can cover 2-3 female flowers, and after fruit setting, the slowly expanding and deformed fruits should be removed in time.
