Cultivation techniques of Honey Pumpkin in Spring

Honey pumpkin plant creeping grape growth, single melon weight 2 to 3 kilograms, fruit about 36 cm long, transverse diameter 14.5 cm, melon hammer-shaped, ripe fruit orange-yellow, meat thick, orange-red, delicate starch, sweet taste, high quality. Early and middle maturity, harvest 85-90 days after planting, spring planting from January to March, autumn planting from July to August, yield per mu 2000 kg. The following mainly introduces the key techniques of spring cultivation of Miben pumpkin. 1. The spring sowing period in Guangdong is generally arranged from January to March. The germination ability of Miben pumpkin seeds is strong, and generally they can be sowed without soaking seeds to accelerate germination. Those sown in advance in early spring can use nutrition cups or bowls for cold prevention and planting after the temperature picks up. If the seeds are sown at the end of February and March, direct seeding (hole sowing) is generally used, with 2-3 seeds per hole, 2 meters between rows, 50 centimeters between plants, and 2-3 centimeters of soil after sowing. 2. Field management 1. Fertilization: turn the soil deeply before sowing, and at the same time apply 2000kg / mu pig and cow manure as base fertilizer. After the plant extends the vine, 15-20 cm from the root, open a ditch to fertilize, apply 500-1000 kg of soil fertilizer or 15-20 kg of urea per mu, and irrigate after fertilization. In the flowering and fruiting period, some potash fertilizer or compound fertilizer should be applied properly, and then fertilized according to the growth of the plant. 2. Irrigation and drainage: after sowing, pumpkin should be drenched with enough water to facilitate seed germination. Before emergence to planting, generally do not drench or less water, after planting to restore the growth of the plant before the extension of the water should not be too much. In addition to timely irrigation after fertilization, in general, watering or irrigation is carried out according to the weather and plant growth, so that the ground is dry and the plant growth is prosperous. It is necessary to do a good job in drainage on rainy days. 3. Pruning and pressing vines: pruning and pressing vines is one of the technical measures for Miben pumpkin to achieve early maturity and high yield. The methods of topping and lateral branch removal can be used for the pruning of pumpkin. The method of topping is to remove the terminal bud when the plant grows to 6-8 true leaves, leaving 3-4 vines and 1-2 melons on each vine. The method of removing the side branches is to leave only one main vine, remove all the son and grandson vines, and begin to press the vines at the length of 40cm to 50cm. 4. Artificial pollination: the pollen is lightly smeared on the stigma of female flowers at 8: 10 o'clock every morning after flowering, and each male flower can be used to pollinate 1-2 female flowers. Third, the main diseases of Miben pumpkin are virus disease and powdery mildew. Virus disease is also called mosaic disease, after the onset of the plant, the leaves are mosaic-like, wrinkled, smaller, and appear dark green tumor-like protuberant spots, fruit deformities, plant obvious atrophy and dwarfing. The more effective measure to control virus disease is to control and eliminate aphids. If diseased plants are found, they should be removed and burned as soon as possible and disinfected with lime to prevent spread. Powdery mildew often occurs in the middle and later stages of growth, and can be controlled by trimethoprim, carbendazim, colloidal sulfur and so on. The main pests of Miben pumpkin are aphids and Huangshou melon, which can be sprayed with 40% dimethoate 600 times 800 times or 10% imidacloprid wettable powder 3000 times 4000 times.
