Gherkin is one of the dominant varieties of early spring vegetables. Its growth period is short, it is listed early, and the economic benefits of cultivation are high. ?
Cultivate strong seedlings: soak in warm water of 50～55°C for 15 minutes before sowing, soak in cold water for 3~4 hours after cooling, make seeds fully absorb water, and then wrap in wet sand cloth or clean towel on tile pot Or mouth cylinder, maintain the temperature of 25 ~ 28 °C, check once every 8 hours, if the humidity is not enough, with warm water shower, protect the water evenly, generally 24 hours after germination, and then move the room to be slow Slowly after sowing. Seedbed disinfection, with 10 grams of 64% antimony or 58% Remycin mixed with fine sand per square meter, was sprinkled into the seedbed, covered with a lid, and the seeds were sandwiched, effectively killing the seeds and seedlings. Timely sowing, in mid-November to early December, about 15 grams per square meter seedbed sowing, field seeding sowing 150 to 250 grams per acre, after sowing with film arch 25 cm high cover to prevent cold damage. When the seedlings thaw and the film needs to be broken to facilitate the seedlings to produce a film. If transplanting seedlings, there are 2 to 3 true leaves that can be planted. ?
Planting management: The results of early harvest cucumber, long harvest time, high yield, yield per mu 3500 ~ 4500kg. We should choose a thick, fertile plot of cultivated land and apply basic fertilizer at a rate of 3000-3500 kg per mu, potassium sulfate 10-20 kg, and calcium calcium 40-50 kg. Before harvesting, timely soil preparation, ripening the soil, and planting for planting. 15 meters wide, 30 cm wide, 30 cm wide and 50 cm wide, or 40 cm long and 60 cm long, 2 plants per pond (or 2 plants), covered with plastic film immediately after the flat surface, broken membranes and planted, and then Cover the membrane, membrane arch 25 to 30 cm high. When the seedlings grow to thrive, peel off the membrane. In the seedling stage, the water requirement is small, the ground temperature is relatively low, watering is less, and water is used to thin the water to make the seedlings. When the root melon begins to harvest, a large number of roots have already formed, and the amount of fertilizer needed is increased. The first fertilizer application can be carried out, and 10 kg of ammonium nitrate or 8 kg of urea can be used to mix 15 kg of common calcium; during the full fruit period, the second time can be pursued. With ammonium nitrate 15 kilograms, calcium sulphate 15 ~ 20 kilograms, mixed topdressing, chase once a week, a small number of times, each pouring fertilizer after pouring enough water. Lack of water and fertilizer is an important cause of malformation and affecting yield. Do not topdress ammonium bicarbonate in the seedling stage to avoid causing nitrogen poisoning in the seedlings. When the seedlings open to 4 to 6 true leaves can start. The main twigs of pruning were dominated by pruning, and the lateral branches were removed. The lateral branches in the upper part could retain the cucurbits. ?
Pest control: The main diseases of cucumber during the whole growth period are downy mildew and bacterial angular spot, which occur alternately or mixed in the field. The prevention and treatment of bacterial keratoses can be sprayed with 30% dt bactericide 500 times in the initial stage of disease, 70% dtm temperature powder 500 to 600 times, or 25% trehalone 600 to 800 times, and agricultural streptomycin 4000 to 5000. Times, or 45% Daisen ammonium water agent 1000 times. The prevention of downy mildew using urea 150 grams plus 500 grams of brown sugar and 50 kilograms of water, every 5 days during the growth of cucumber, continuous spray 4 to 5 times, requiring morning spray, spray on the back of the leaves. Chemicals can be used to control 40% of aluminum alfa 200 times, 75% of chlorothalonil 600 times, 70% of mancozeb 500 times, 25% of methane cadmium 400 to 600 times, 64% of antivirals 400 times, or 25% Poison Mn-Zn is sprayed 400 to 600 times, or 1000 to 2000 times to root. Various agents are used interchangeably. When downy mildew mixed with bacterial keratoses can be used 30% dt fungicide 500 times plus 40% diethylaluminophosphate 200 times; 30% dt bactericide 500 times plus 25% metalaxyl 800 times; or 1 million Unit streptomycin sulfate 150ppm plus 15% triadimefon 2000 times mixed spray. When downy mildew is mixed with anthrax, it can be sprayed with 40% diethylaluminium phosphate 200 times and 25% carbendazim. 40% Dimethoate EC 800 times; 30% Trimethoprim 1000 times, 20% Trimethoprim EC 1000-1200 times; 50% diazinon EC 800-1000 times; or 24% Wan Ling Shui agent 800 times liquid spray.
