I. Selection of varieties
The general selection requirement is strong growth, thickness and short syllabi. Leaf is deep green. The three to five knots began with a high rate of melons。
Ii. Selection of the land
The selection of plots with fertile soil, deep soil depths, which do not easily result in water accumulation and continuous cucumber planting for up to two years, is preferable to fields where root and root crops are planted without the use of herbicides, such as fields with peanuts and soybeans。
Iii. Cultivating seedlings
In general, cucumber can be grown from late september to the end of december。
1. Pre-sterilization seed
The seedlings are first decontaminated for 8 to 10 minutes with a warm water of about 50 °c ~ 60 °c. The seeds are then immersed until around 30 °c, then immersed for 5 to 6 hours, drained from the seed membrane to leachate and placed in an air-breathing wet gauze, in a 25 to 30 ° shed, or in a greenhouse for seeding。
2. Local planting of prepared nutrition
Nutrient soil is calculated as a cube: 7-8 seedbeds + 5 fully decomposed farm fats 4-5 + 0. 5 + 1 kg phosphorous + 0. 1 kg 70% dyson manganese zinc + 10 ~ 15 kg grasswood + 0. 1 kg of octophos-methyl, which is then applied after a five- to seven-day period after they have all been flatted。
3. Shrimp management
Shrimp management is mainly temperature-controlled wetting and water is preferably sprayed with a canteen, which is selected on the morning of the sun, and is followed by timely ventilation and wetting, while leaf spraying of 0. 2% potassium phosphate + 1% glucose is taken into account in combination with pest control to enhance the resistance of the seedling to cold。
Iv. Planting
The first 10 to 15 days of shacks were installed, and seven days later the shacks were watered with water and three days with ventilation. The production and quality can be improved by having three to five days before planting, when the ground is levelled and fertilized, usually from 5,000 to 5,500 kg of decomposition organic fertilizer per acre, 80 to 100 kg of compound fertilizer as base fertilizer, and by adding fertilizers containing a number of moderate and trace elements, such as calcium and boron。
In light of changes in temperature, the temperature in the shed is maintained at about 25°c, usually at a distance of 25 to 27 cm and 60 to 65 cm, with approximately 4,000 to 4,500 units per acre。
Saplings are immersed in liquids with 1 pack of fungus + 1 pack of mucus + 1 bag of water — 30 pounds of water — and can be taken out of static for 1 to 2 hours after immersion of about 3 to 5 seconds。
The plant is usually set at a morning temperature of about 10°c - 15°c, with a watering of a mild seedling, careful not to be applied to the fattening of the potassium nitrogen phosphorus, and should be fed with silicon or calcium fertilizer, and 6 kg of silicon fertilizer per acre。
Medium-term management
After planting, the first vine management needs to be careful that all the buds except the main stem must be wiped out, before the cucumbers reach the shelf, with two or three strong twigs left to develop and the extra twigs cut。
(c) prevention of diseases in a timely manner, prevention of white powder and frost, spraying of seven to 10 days of frosted zinc leaf with frosting and fungal diseases。
Vi. Medium-term management
It is mainly a rational melon and root-rearing technique, which is the third to leave a third melon in four leaves from the second. It avoids defertilization in growth and should therefore be applied in combination with nitrogen, phosphorus and potassium fertilizer. Attention is also being paid to the timely prevention of folic anthrax, which is sprayed twice in five days with 1,500 times etheramide, 1,500 times baccalaure, 800 times the opening dollar. With the cucumbers, the cucumbers grow relatively straight, water the water with 1:50 beers, and the flowers are more colorful。
