The cultivation of spring squash in the spring is usually done by seedling transplanting. The seedling transplanting can be used in the morning market to increase the income.

First, choose a good species

Spring cultivars can choose a nest of monkeys, early green, black beauty, Algerian zucchini and so on.

Second, seed processing

Zucchini should be sown before sowing, soaking, germination and disinfection. When selecting the seedlings, remove the impurities, small seeds, and pod seeds, and choose to keep full-grown seeds. The amount of seed used for planting 1 mu of land is 0.3 kg. After choosing a good seed, soak it in cold water, then scoop up and put it in water of 50°C-55°C. Stir constantly, and continue soaking for 4-6 hours after cooling for 15-20 minutes to 25°C-30°C. To reduce seed germs, remove the seeds and soak them with 1% potassium permanganate solution for 20-30 minutes or soak them with 10% sodium phosphate solution for 15 minutes, remove and place in a wet gauze bag or tile pot and place at 25°C. Under the temperature, germination, 2 days after the radicle grew about 0.3 cm can be sown.

Third, sowing

Pre-prepared nutritious soil, then fill enough water. The use of nutritional seedlings nursery, each nutrient seeding a good seed buds, seed bud tip down, sow 2 cm thick after sowing.

Fourth, control the temperature and humidity

After sowing, should maintain a higher temperature, during the day 25 °C -30 °C, night 15 °C -20 °C, relative humidity of 80% -90%, generally 3-4 days to emerge. When 80% of the soil is unearthed, it is timely ventilated and cooled to maintain the temperature of 20°C-25°C during the day and 13°C at night so as to promote the thickening of seedlings, accelerate the differentiation of female flowers, and prevent leggy seedlings from becoming prolonged. Gradually increase the amount of ventilation 10 days before planting, cooling and hardening seedlings. General seedlings need to control the watering, no drought, no pouring.

Fifth, apply base fertilizer

Before planting, sufficient base fertilizer should be applied, and 3,000-5,000 kilograms of high-quality organic fertilizer, 100 kilograms of superphosphate, 25 kilograms of potassium sulfate, 100 kilograms of cake fertilizer and 25 kilograms of diammonium phosphate should be applied per acre.

Sixth, appropriate colonization

Zucchini requires less temperature than other melons. The local temperature stability can reach above 6°C-8°C, and it can be planted when the temperature is above 10°C. The standard of strong seedlings is 3-4 true leaves of seedlings, 0.4-0.5 cm thick stems, up to 15 cm strains, and dark green leaves.

VII. Density of colonization

The greenhouses were planted on the ridges and ridges, with a row spacing of 80 cm, a row spacing of 60 cm and a spacing of 45 cm.
