The melon, also known as the melon, is a variant of the melon, which belongs to the cucurbitaceae. China's Guangdong and Guangxi have a long history of cultivation. Planting in the north is less. In order to adjust the planting structure, improve economic efficiency and enrich the supply variety, the Mengke Horticultural Institute in Shuangta District of Chaoyang City introduced the cultivation experiment in 2001-2002 and achieved success. The solar greenhouse is planted with 130 square meters and the income is 2,870 yuan. After deducting the cost of 600 yuan, the net income is 2270 yuan, and the net income of 667 square meters is 11,350 yuan. The specific cultivation techniques are as follows.
First, the variety selection
Choose high-quality, high-yield, resistant to pests and diseases, strong resistance, adaptability, and good commercial quality. The melon is oblong, 15-20 cm long, about 10 cm in diameter, and dark green.
Second, nursery
Seedlings were planted with nutrients and bred on January 27 before the Spring Festival. The seeds are first soaked in 55 ° C hot water for 20 minutes, stirred while soaking, and then soaked in water at 30 ° C for about 20 hours. When the seeds are not dry, they are germinated. When the seed bud grows to the equivalent of 1/3 of the seed, it is planted into the nutrient bowl and seeded in a solar greenhouse.
Third, colonization
1. Prepare the base fertilizer before planting, and apply more than 3,500 kg of high-quality farmyard manure per 667 square meters. The base fertilizer is mainly based on the application of a single line of 1 meter. The greenhouse was disinfected before planting, and the mixture was ignited with 80% dichlorvos and sesame oil mixed with sawdust and sulfur powder, sealed for 1 day and night, and planted after odorless and odorless.
2. The planting time and method were planted on March 1st, the planting distance was 20 cm, the single row distance was 1 meter, and the average 667 square meters planted 3300-3400 plants. The sulcus was firmly planted and the mulch was buckled.
Fourth, post-plant management
1. Fertilizer management The melon is poured 16 times in the whole growth cycle, including 6 in the early growth period and 10 in the middle and late growth stages. When the flowering is first, the first melon walnut is poured into a small water, and the film is under dark irrigation, and the small water is poured. After cascading, water should be poured once every 3-4 days, and it should not be watered in the evening. In the early stage of growth, 15 kg of urea, 15 kg of diammonium phosphate, 5 kg of potassium sulphate and 1000 kg of chicken manure were applied, and the application was carried out twice to supplement the growth requirements of each growth period.
2, increase the light to use a functional film with good light transmission, keep the film surface clean in winter and spring to increase the light intensity.
3. Control the indoor temperature and humidity according to the requirements of temperature and humidity in different growth stages of melon, and control the temperature and humidity in the shed to the appropriate range through measures such as ground cover, under-film dark irrigation, ventilation and moisture removal, and temperature control. Inside. The temperature is generally controlled between 15 ° C and 30 ° C.
4. Pest control is based on the principle of prevention and control of agricultural measures, supplemented by chemical control, and does not use high-toxic and high-residue pesticides. The main pests are whitefly mites, sprayed with chlorpyrifos and aphids for a net control; gray mold can be sprayed with anti-mildew. After one month of colonization, the drug was sprayed once every 7 days, and the drug solution was sprayed 5 times.
The above is about the planting technology of melons, I hope to have some help for everyone, please pay attention to the Hui Nong School for more details.
