First, choose the appropriate varieties: selection of disease-resistant, high-quality, high yield, strong resistance, good varieties of goods, and according to the different planting seasons, select the appropriate planting varieties. Optional Yanbai cucumber, Jinyou 1, Jinyou 4, Jinyou 5, Jinchun 4 and other varieties.
Second, the selection of land: the choice of drainage and irrigation is convenient, deep soil, loose, fertile, water conservation and fertility of the soil cultivation, to avoid continuous cropping with the cucurbitaceae vegetables.
Third, sowing nursery: generally use seedling transplanting.
(a) sowing date: Spring cucumber nursery seedlings in the middle and late January sowing, cold bed nursery in early February and early March sowing; autumn cucumber sowing in mid-July-September. Seeds 100-150 grams per mu.
(B) the preparation of nutrient soil: Before sowing by compost 5 + 5 of paddy soil + 0.3 ~ 0.5% of superphosphate and appropriate amount of plant ash to prepare nutrient soil, and bed soil for disinfection.
(3) Seed soaking and germination: Seeds are first soaked with warm soup (2 portions of boiled water and 1/2 portion of cold water) for 15 minutes, and are continuously agitated, then washed out and soaked in water at about 25°C for 3-4 hours, and soaked in 25-30. The germination was stopped for 2-3 days under the condition of °C, and the germination was stopped when the radicle length was 2-3 mm.
(IV) Seeding and nursery management: Each seed should sow 2 seeds, cover 0.5-1 cm thick nutritious soil or “stone millet†after sowing, soak the bottom water, cover with plastic film in early spring, and wait until 70% of seed cotyledons are unearthed. After the removal of the plastic film into a small shed, strengthen seedling management, seedling age 35-40 days. Summer and autumn sowing transplanting to shade, anti-rainstorm, seedling age 20-30 days. Colonization was carried out 7 days before colonization.
4. Site preparation: Deeply plunge the soil more than 30 cm in 10-15 days before planting and press 133-150 cm wide to make a high compartment.
5. Base fertilizer: Combine site preparation, apply 2500-3000 kilograms of farmyard manure and 60-100 kilograms of compound fertilizer per acre as base fertilizer, mix the fertilizer with the soil in the nest, and timely cover and cover the plastic film.
Sixth, timely planting: early maturing soil temperature stable in more than 12 °C planting, greenhouse early maturing planted in mid-February, small plastic shed precocious cultivation in late February to early March planting; summer and autumn cucumber in cloudy or sunny evening colonization In the autumn, the planting will be planted from late July to mid-September. The plant will be planted in deep trenches, with two compartments in each compartment. The recession will be from 40 cm to 50 cm and the planting will be about 2000 litters. Each plant will be planted with 2 plants and should not be deep when planting. Planting, planting and pouring water after the rooting.
Seven, field management
(1) Fertilizer and water management: 1,000 kg of diluted fecal water is applied to each mu in the seedling stage and early flowering period, and 2 top dressings are harvested once per fruiting period in the fruiting period, and the 1:2 fecal water concentration is better. Chong Shi ternary compound fertilizer 4-5 kg.
(2) Racking and pruning: Cucumbers begin to appear at tendrils, and when they are 7-10 leaves, they are strung together and tied with vines. After every 4-6 knots, they are crushed with vines once, and excessive male flowers, tendrils, and side vines can be destroyed. And the yellow leaves on the lower part of the plant. When straddling, people usually use a human-backed frame. Each socket is inserted with a bamboo pole, and two bamboo poles are tied to adult fonts.
(c) pest control: the use of agricultural, biological, physical and chemical methods of comprehensive prevention and control.
1, damping-off disease: more seedlings occur, can be sprayed with 75% chlorothalonil WP 800 times after sowing;
2, downy mildew: the initial onset from the lower leaves, severe onset of high temperature and humidity. The use of high-bay cultivation can reduce the occurrence of disease, and 72.7% of Propocarb Water (Pric) 550-700 times spray can be used to control the disease at the early stage of disease.
3, powdery mildew: The disease began in the late melon, and harm other melon crops. At the beginning of the disease, 15% triadimefon (triadonine wettable powder) 1500 times, myclobutanil, flusilazole and other pesticides were sprayed for prevention and treatment.
4, keratopathies: leaf back water spots like gray spots, polygonal, yellow blister positive leaves, and downy mildew easily confused, two diseases often mixed hair, usually in the beginning of April onset. At the beginning of the disease, 77% copper hydroxide 600-800 times solution, 72% agricultural streptomycin 4000 times solution, or 2% kasugamycin 400-500 times solution can be used for spraying.
5. Epidemics: The incidence of cucumber in early spring is light, and the occurrence of cucumber in summer and autumn is heavy. It is easy to occur after planting until the pumping stage. Available, 72.7% of Propomos Water (Pric) 550-700 times spray;
6. Locust: Use 10% imidacloprid (Dajin Chen, buds and nets) 1500-2000 times liquid (40 g/mu), or 2.5% Lambda-cyhalothrin water emulsion (Kung Fu) 2500-3000 times liquid (20- 24 ml/mu), or 72.7% of Proplocarb (Prok) 550-700 times spray control.
7, Huang Shougua: After planting to the early flowering stage damage, 50% phoxim 1500 times can be used to irrigate the roots, adults with 2.5% lambda-cyhalothrin emulsion (Kung Fu) 2000 times liquid (30 ml/mu) spray control .
VIII, timely harvesting and listing: General flowering to maturity about 10-12 days harvest, root melon early harvest, full fruit period 2 days once. Note that it is necessary to take the drug safety interval before harvesting.
