Temperature: After the plants are sitting on the melon, in order to accelerate their growth, the temperature in the shed must be properly increased. The daytime temperature should be controlled at 25°C~28°C and nighttime at 15°C~18°C to promote plant growth and increase yield. Because of the strong light requirements of the zucchini, in actual operation, early release can be used to put grass curtain, every 3 to 5 days to wipe the drip-free greenhouse film, remove the grass on the film, dust, back wall hanging within the shed Reflective film, increase the intensity of light in the shed; if you encounter continuous rain, snow weather, you can spray photosynthetic accelerator to increase photosynthesis.
Fertilizer: When the first melon sits and grows to 10 centimeters, the second water can be poured. Afterwards, the zucchini will gradually enter the fruitful period. In the management of greenhouses, fertilization and watering should be carried out according to the weather and plant development.
Artificial pollination: When the shed temperature reaches 20°C every day from 8 to 9 am, the newly opened male flower is removed, the petals are removed, and the stamen pollen is lightly applied to the stigma of female pedestal. Also, 20- to 30-PPM of 2.4-D or 30 can be used. ~40PPM of the female flower with the anti-dropping pigment and applied with a brush between the base of the style and the base of the flower. If the artificial pollination is combined with 2.4-D or anti-dropping element, the effect is better.
Hangman: In each ridge, 1.8 meters above the courgette, a small steel wire is pulled in the north and south direction. Each garden gourd is tied with a sling. The upper head is tied to the small steel wire and the lower tie is tied with a sling. After planting melons, the plants will not tilt sideways. When leaving the vine, leave one for each plant, and wipe off the remaining axillary buds as soon as possible. At the same time, the old leaves that have lost their function at the bottom and yellow are often destroyed, reducing nutrient consumption. In the growth process of zucchini, many tendrils tend to be produced. In order to save nutrition, tendrils should be erased as soon as possible.
