It took 25-30 days for the roots to be harvested. During this period, the roots were preserved by heat preservation, and the root melon was harvested until the fifth melon was harvested in the melon period, which took 40-50 days. In order to enhance ventilation and promote fruit development. After 6 melons were harvested, the plants began to decline, and during this period, the melons should be preserved to extend the growth period.
[Temperature Management]
Do not ventilate within 5 days after planting. Keep the insulation of the enclosure and cover the straw at night to promote mild seedlings. Pay attention to maintaining daytime temperature 25-30°C and nighttime 15-18°C. Appropriate ventilation after easing the seedlings, the daytime temperature in the shed is controlled at about 25°C and 13-15°C at night. During the flowering period, the temperature in the shed can be reduced to 23-25°C and maintained at 10-15°C during the night. In the rainy days, when the temperature in the shed is not lower than 15°C, the time for rewinding and transmitting light should be extended as much as possible. After entering April, when the outside air temperature is stable above 12°C, it can be ventilated overnight.
[Fat Management]
Zucchini is suitable for moist soil, and 5-7 days after planting, the water will be irrigated with water. After watering with urea 8 kg per 667 m 2 or 2000 kg of diluted dung water, watering should be controlled before rooting. May not pour. After the first melon sat down, the second melon was topped with water and topdressing 15 kg of urea per 667 square meters. Into the prosperous period, pouring water once every 5-7 days, every 2 to 3 times of water to chase 1 fat, 2-3 times.
Artificial Pollination
Artificial pollination is preferably performed at 9-10 am, and can also be applied to the base of the corolla with 30-40 mg/L of 2,4-D or 50 mg/L of non-arsenic, or with a small sprayer.
ã€Shu Hua Shu Guo】
Zucchini leaves a normal, growing, small melon between each leaf, removing it as early as possible.
[bagging technology]
In spring shed cultivation of zucchini, due to high humidity, suitable temperature, pathogenic bacteria occur seriously, especially the incidence of gray mold, Sclerotinia, high incidence of serious impact on the yield and efficiency. The use of bagging technology for prevention is an easy and effective method.
(1) Bagging production and specifications. The use of old newspapers or magazines to grow 20 cm, 10 cm wide bag, one end of the paper bag with a stapler sealed or sealed with glue.
(2) Use technical methods. Before bagging, the bag was treated with 2.5% extinction dust, so that the bag was covered with dust particles to form a protective film. When the female flower is open, remove 2/3 of the corolla after adding 0,1 % of xeroxin from 30 mg/l of 2,4-D every day at approximately 8 am. Then, the treated bag is gently placed on the stalk and the tampons are sealed with a tack.
(3) supporting measures for bagging. In order to prevent the ground moisture from being wetted, it is necessary to use dry straw or other dried materials to protect the bag from moisture and protect the fruit from insect infestation.
