癞可丽南瓜 cultivation technique

Qi Keli is a new excellent pumpkin variety introduced from Jiangsu Zhengda Seed Co., Ltd. in Thailand. It was introduced into the city in 1998. It has the characteristics of early maturity, beautiful appearance and excellent quality. It has become a village in the city, and the labor farmers have become rich. Excellent variety.

First, the characteristics of the characteristics

The plants are strong, heat-resistant, disease-resistant and adaptable. The leaves are large, 5-lobed, nearly heart-shaped, dark green, long petiole. The first female flower is born in the main vine 13-15, and the female flower is reproduced every 6-7 knots later, and the fruit setting rate is high. The fruit is flat and round, and the skin is dark green. The surface of the fruit is densely poplar-like. The weight of the single melon is 2.5kg. It is thick and brown, and the meat is sweet and dense. It is very resistant to storage and transportation. It is mainly composed of main vines, 3 to 4 single-planted melons, and 3,500 to 4,000 kg of 667 m2.

Second, cultivation techniques

1. Sowing at the right time, cultivating the seedling period of strong seedlings is suitable in mid-July, using small arch sheds and nutrition bags for seedlings, soaking seeds with warm water of 55 °C before sowing, and naturally sown in the nutrition bag of the seedbed after cooling, due to positive value In the hot season, the seeds may not germinate. After the sowing, the water was poured, and the seedbed was arched into a plastic shed. The temperature of the small shed is controlled at 26~30°C during the day and 16°C at night. The shed should be ventilated and dehumidified in time and pay attention to prevention and cure. Seedling age 17 to 21 days, 2 leaves 1 heart can be transplanted.

2. Soil preparation and planting In summer and autumn, there are more rainwater cultivation. The land should be selected with high topography, deep soil layer, loose and fertile soil, and well-filled land. It is cultivated with sorghum, with a width of 150cm, a height of 40cm, and a width of 40cm. The surface of the sputum should be straight and covered with a black mulch to improve the ground temperature and prevent weeds in the field. Combined with land preparation, 667m2 is applied with 2000kg of high-quality organic fertilizer, 50kg of superphosphate, 10kg of potassium sulfate, fully mixed, and applied to the planting ditch as a base fertilizer during land preparation. Two rows of colonization, plant spacing 60cm, row spacing 100cm. 450 plants were planted in 667m2. When the seedling height is 30cm, flatten the scaffolding and lead the vines to the shelves.

3. Strengthen field management

(1) The purpose of rational pruning is to ensure the fruit setting rate. Generally, the side branches of the first female flower are all removed, and the above lateral branches are adjusted to grow. The plant grows vigorously and can leave 4 to 5 side vines. The growth of the plant can leave 2 to 3 side vines, and the plant growth may be weak. Leave the side branches. The diseased leaves and old leaves should also be removed in time to facilitate ventilation and light transmission in the field.

(2) Timely topdressing plants can be traced once after harvesting, and 20 kg of urea is applied per 667 m2, 15 kg of superphosphate, 10 kg of potassium sulfate, and water is applied. The second top dressing can be the first in 70% of plants. When the young melon grows to a large goose egg, 50 kg of high-efficiency compound fertilizer is applied per 667 m2, and the hole is applied at a distance of 25 cm from the root of the melon to promote fruit enlargement.

(3) Timely prevention and control of summer and autumn planting when there is more rain, it is necessary to drain and prevent flooding in time, so that there is no water in the field.

(4) Artificial pollination In order to increase the fruit setting rate of pumpkin, artificial supplementary pollination must be carried out. Artificial pollination is carried out every morning from 6 to 9 o'clock. The male flowers that are open on the day are taken down, the corolla is peeled off, the flower handle is pinched, and the pollen is gently applied to the head of the flowering female flower. One male flower can be given 2 to 3 flowers. female flower.

4. Harvest

Root melon should be harvested in advance to facilitate robust growth and continuous results. In the local market, the cantaloupe can be harvested. If it is to be exported, the skin wax powder should be thickened after the melon is cooked, and the tumor will be harvested when it is raised. Old ripe melons are stored properly and can be stored for 3 to 4 months, which can be supplied to the market.
