1. Nursery

The suitable sowing date is from late January to early February. Seedlings are raised in idle greenhouses. The farmyard manure and soil are sieved and mixed with appropriate amount of potassium sulfate compound fertilizer and evenly put into a nutrient bowl and placed in the seedbed. Then the footing water is poured, and the seeds that have sunned or promoted the buds are placed in the pot, and the cover soil is 1.5-2. cm. Finally, a small arch shed was affixed. In the evening, a small shed was covered with straw to protect the seedlings. After the emergence of seedlings, timely lifting of the ventilation of the small arch to prevent leggy. The daytime temperature is maintained at 20-30°C and nighttime is not less than 8°C.

2. Colonization

When the seedling grows to 3 leaves and 1 heart, it can be planted. Because zucchini plants are slow and slow, they can be transplanted on a cloudy or sunny afternoon. If transplanted on sunny days, cover grass or other shades in time to facilitate the return of seedlings after transplanting. Due to the lower temperature at night, the small arch sheds were well-sealed and covered in a timely manner after the colonization, and straw grasses were used to incubate at night to facilitate its growth. Sunny days and mornings, the cover film and grasshoppers were promptly opened to ensure that the plants were fully illuminated. On a cloudy day, the plants can be exposed by covering the grasshoppers and coverings according to the temperature in the greenhouse. During the period of easing, the shed should be maintained at 25 to 30°C and 15 to 18°C ​​at night. After easing the seedlings, the temperature should be appropriately reduced, about 25°C during the day and about 10°C at night. Afterwards, the amount of ventilation will increase as the weather warms. Remove the inner arch shed at night temperatures above 10°C. With the wind cooling, the use of non-drip film, covering the film when planting, taking the drip irrigation under the membrane, can effectively reduce the humidity inside the greenhouse to prevent the occurrence of diseases.

3. Post-planting management

(1) fertilizer and water management. The zucchini is a favorite fertilizer vegetable. Before applying the planting, the base fertilizer is applied. The ditch is ridged, and the planting distance is 60 cm and the plant spacing is 50 cm. Before the planting, irrigating the water, controlling the water to bloom and setting fruit; After the first melon is seated, pour a water, after the water management according to the principle of “watering melon without watering flowers”; the melon period needs large amount of water, combined with watering Crushing potassium sulfate compound fertilizer 30 kg per 667 square meters. During the period, it is also possible to use the leaching solution of soybean cake to compost. The effect of dressing fertilizer outside the root is quick and easy. Potassium dihydrogen phosphate, urea, foliar and so on can be sprayed.

(2) Use hormones to increase production and increase efficiency. When the zucchini seedlings grow to 4 leaves, 150 mg/kg ethephon solution is added to spray the seedlings with a 0.2% to 0.4% solution for a long time. 10 to 15 days spray once, even spray 3 times, can make the seedling leaves dark green color, students served as robust, increase female flowers, drought resistance, cold resistance and disease resistance.

(3) Plant adjustment and artificial pollination. In the middle of the growth of zucchini, because the outside temperature rises, the plants grow faster and the stems and vines squat on the ground. In order to fully receive the light, the sick, old leaves and lateral buds and tendrils should be removed in time, and the disease can be prevented and nutrient consumption reduced. Take vines to increase lighting. In order to increase the rate of sitting, 20 to 30 mg/kg of 2,4-D solution can be applied to female stigmas or artificial pollination from 8 to 9 am every day.

4. reward

When the root melon grows to about 0.5 kilograms, it is timely picked and listed so as not to affect the growth of the young melon on the following node. Afterwards, with the increase of temperature, the growth speeds up, and the quality of picking melons can be appropriately enlarged.

5. Pest Control

Insect pests are mainly locusts, leaf miners, etc. Diseases include viral diseases, gray mold, and powdery mildew. Can be treated with symptomatic drugs.
