Now, it is during the spring planting time for cucumber seedlings. The cultivation techniques of this cucumber are now described below for reference.
First, nursery
1. Select species. The varieties that are resistant to disease, strong in resistance, good in commodity, and high in yield are selected, such as Jinyou No. 10 and Boai No. 3.
2. Seed treatment. Soak the seed in warm water of 55°C for 10-15 minutes, and continue stirring until the water temperature drops to 30°C, then soak for 3-4 hours, then wash the seed repeatedly with clean water, dry the mucus, and then dry the germination. Prevention of diseases such as scabs and anthrax. The soaked seeds are wrapped in a clean, damp cloth and germinated at 28°C to 32°C for 1 to 2 days. When 70% of the seeds are whitened, they can be sowed.
3. Seedbed preparation. The garden soil or field soil that has not been used for 3 to 5 years to grow the melon vegetables is mixed well with the organic fertilizer with good quality and decomposed at a ratio of 3:1, and 2 kg of the three-element compound fertilizer is added per cubic meter. Mix 50% carbendazim WP and 50% thiram wettable powder 1:1, mix 8 to 10 grams of agent per square meter and 15 to 30 grams of fine soil, 2/3 of which is used to make beds. 1/3 is used for covering after sowing.
4. Seedlings. The nursery can be carried out in a warming greenhouse or a solar greenhouse. Nutrient crops, nutrients, or seedlings can be used.
5. Sow. Dig seedlings in a 15 cm deep seedbed, and then spread a layer of grass ash (or fine sand) on the bottom of the bed. Then lay a bed with 10 cm soil thickness, irrigating the water, and drain the water to draw a 10 cm 10 cm square on the seedling bed. 10 cm deep, put a seed in the center of each piece, covered with medicine soil thickness 2 cm, and then seedlings covered with plastic film on the bed to keep moist.
Second, seedling management
1. Temperature management. Sowing to unearthed daytime temperature should be controlled at 28°C～32°C and nighttime at 10°C～18°C; unearthed to break heart daytime temperature should be controlled at 25°C～30°C, nighttime 16°C～18°C; broken heart to set daylight temperature It is controlled at 20°C～25°C and nighttime at 12°C～16°C.
2. Moisture management. Seedlings should be properly controlled, see dry see wet, watering thoroughly.
3 hardening seedlings. 7 to 10 days before planting, water should be controlled to increase the amount of ventilation for low-temperature hardening. Daytime temperatures range from 18°C ​​to 20°C and nighttime from 8°C to 10°C. When the seedlings reach the height of 15 cm, 3 leaves and 1 heart, the seedlings can be planted when they are about 35 days old.
Third, colonization
1. Soil preparation. The base fertilizer is mainly composed of mature organic fertilizer, supplemented by chemical fertilizer and compound fertilizer. In general, organic fertilizer is applied at 4,500 to 5,500 kilograms per mu, compound fertilizer is 20 to 50 kilograms, and superphosphate is 25 to 50 kilograms.
2. Disinfection. 10 to 15 days before planting, arbors or greenhouses with sulphur powder 2 to 3 kilograms, plus 80% of dioxin 127 kg of dichlorvos, mixed with sawdust, and ignited in groups, sealed greenhouses last night, disinfection, odorless after colonization.
3. Colonization. Colonization was carried out at the beginning of March. Row spacing was 50-60 cm and plant spacing was 25 cm.
IV. Management after planting
1. Water and fertilizer management. After planting, water should be poured for 1 time, and water should not be poured afterwards. In the early days of the squash and the period of melon growth, the water requirement increases. It is necessary to adjust the watering interval due to growth, weather and other factors. Each time you have to pour water, it should be done in the sunny morning. You can also use under-membrane irrigation, through the ventilation. Adjust humidity.
Into the melon period should be combined with water and fertilization, the initial period of every two water chase a fertilizer, the melon during the peak period of a water chase a fertilizer, topdressing nitrogen fertilizer every time 2 ~ 3 kg per kilogram, the middle of the growth of potassium fertilizer 4 kg. The melon period is treated with 0.3% to 0.5% potassium dihydrogen phosphate solution for foliar spraying 2 or 3 times, adjusting the melons and promoting the growth of melon strips.
2. Temperature and humidity management. After the planting, the general temperature in the morning is controlled at 25°C-32°C, 25°C-20°C in the afternoon and 15°C at night.
Greenhouse cucumber relative humidity to be controlled below 85%, as far as possible to make the cucumber leaves do not dew, no dripping, the use of under-membrane irrigation, watering and timely release of moisture. When the outside temperature is higher than 12°C, the air can be released overnight.
3. Plant adjustments. When the melon seedlings are ran out, they can use a bamboo or wooden stick to take a 1.5-meter-high ergonomic stand in time. The vines can be tied together for about one foot, and then every 3 to 4 knots will be tied once. Tied vines are generally tied to the 1-2 sections of the melon. When the vines are tied, tendrils, diseased leaves, and yellow leaves should be removed. Root melon should be picked in time to avoid embarrassment.
