When is a good time to plant gourds? How to increase planting yield?

Zucchini has strong adaptability and can be compared with towel gourd, wax gourd and pumpkin. This vegetable is grown in both the north and the south. Due to different climatic conditions, the sowing time is also different. This is a warm crop. The optimum temperature for seed germination is above 65438 05℃, and the optimum temperature for seed growth is 20 ~ 25℃. When the temperature is lower than 10℃, the growth and development will be hindered, while when the temperature is higher than 36℃, premature aging will occur due to excessive transpiration. Therefore, in the south, melons are usually sown around Tomb-Sweeping Day, but in the north, they are sown around the solar term in Grain Rain.

Seed treatment. Before sowing, in order to ensure the germination rate, the seeds of that year should be selected. The seeds should be scalded in water at 70℃ and stirred quickly. After the water temperature drops to 30℃, soak the seeds for half a day and take them out for germination. 80% seeds can be sown when exposed.

Plant in time. Pumpkin seedlings are 30 ~ 40 days old and can be planted with 3 ~ 4 true leaves. Planting is carried out in sunny morning or afternoon. Although there will be some wilting in sunny days, the ground temperature is relatively high. After sowing, the seedlings grow fast and early, much shorter than in rainy days. Water the seedbed before transplanting to prevent the root system from being damaged during transplanting. It is best to transplant with soil.

Before planting, base fertilizer should be applied, and it is advisable to decompose farmyard manure. Ridge farming can be carried out if conditions permit. It is suggested to apply 2500 kg of farm manure per mu, or special fertilizer for vegetables or sulfur-containing compound fertilizer, per mu 150 kg. Pay attention to planting density when planting. Plant spacing is 0.7m Remember to water the roots once after planting.

Through artificial pollination, gourd can improve fruit setting rate. Usually, after the male and female flowers bloom, they are dipped in pollen with a brush on a sunny morning, and then touch the pistil of the female flower. If bees assist pollination, it can save the trouble of artificial pollination. Usually, pollination is not needed for flowering after summer. Because of short growth period, dry fruit shape, poor ornamental quality and low value, pollination can be stopped.
