1. Soil selection and soil preparation
Select pH 6.0-7.5, rich in organic matter, good irrigation and drainage, water retention and fertilizer of the sticky sandy loam soil, bogey and melon crops continuous cropping, the former is best rice field. The site preparation uses deep ditch sorghum, which has a width of 1.8-2.0 meters (even ditch), a pod height of 30 cm, a north-south trend, double-row planting, and 30 cm spacing.
2, sowing nursery
Seed sowing from early spring to March, summer and autumn plant from June to August. Spring sowing with seed soaking germination or mulching film coverage live, soaking in summer and autumn sowing live or dry seed can be. Immersion germination is commonly used in the sowing of cucumbers, and it is sterilized with warm water of 50-55°C for 10 minutes, and constantly stirred to prevent scalding. Then soaked in warm water at about 30°C for 4 - 6 hours, rinsed, rinsed, drained, moisturized and germinated in a 28-30°C incubator or warm place, germination started 20 hours later. In early spring, small sheds are used to incubate and raise seedlings, and nursery cups or seedbeds are used to raise seedlings. Seedlings are planted at 15-20 days (2 true leaves) when they are planted on a sunny evening. Pay attention to the protection of the root system, leaching before raising seedlings, and ordering when raising seedlings. Do soil planting to prevent root damage.
3, fertilizer and water management and earth
The application of base fertilizer is one of the keys to stable production and high yield. Cucumber has a good response to basal fertilizer. During the site preparation, deep-growing and decomposing organic fertilizer is added. Mushi 2000 kg-3000 kg, hair fertilizer 50 kg and superphosphate 30 kg are used as base fertilizer. When the plants have 2-3 true leaves, the top dressing is started. Cucumber roots have weak absorption and are sensitive to high concentrations of fertilizers. Topdressing is based on the principle of "diligent application and thin application". Fertilizer is applied once every 6-8 days, and urea is between 5 kg and 6 kg. When the tendrils appear, combine the cultivating and weeding soil to fertilize the soil, harvest the first batch of melon and then fertilize the soil 1 times, Mushi peanut bran 15 kg-20 kg, compound fertilizer 30 kg, potassium fertilizer 10 kg. In summer and autumn, due to high temperatures, rapid growth and development, and rapid aging, coupled with large rainfall, fertilizer and water loss, in addition to the base fertilizer, to top dressing. 1-2 tablets of true leaf stage and harvesting of the first batch of melon soil after fertilizing 1 time, pay attention to phosphorus and potassium fertilizer, in order to avoid steep, premature aging. Spring cucumber seedlings need to control moisture. During the flowering period, the amount of water needed was the most. In sunny days, the water was usually sprayed once a day, and the drought was flooded once a day for 3-5 days. We must do flood prevention work during rainy days.
4. Stretching and arranging
When the tendrils appear, it is often used to cross the bamboo and lead the vine. The vine was introduced after the tendrils appeared. The vines were introduced once every 3-4 days to make the plants evenly distributed and carried out in the late evening. Whether the cucumber is pruned depends on the variety, the main vine results generally do not pruning; the main side of the vine results or side vine results, to pick the top pruning, generally less than 8 nodes below the side of vines cut off, more than 9 branches stay 3 after the top pick The main vine spreads around 30 knots.
