Stingless micro-cucumber, also known as the Dutch cucumber, is often used as a seedling for nutrition. Its nutrient-based formula: Soil grown in the field without vegetative melons and rotted and sifted organic fertilizers are mixed in a ratio of 7:3 or 6:4. If fertility is insufficient, 100g of potassium dihydrogen phosphate is added per cubic meter, and the mixture is fully mixed. Within the nutrition bowl, the width of the seedlings is 1.2-1.5 meters.
Before sowing, the nutritional bowl should be poured with water, then the seeds should be sowed. Seeds can be soaked before germination, and then sowing; can also be soaked 4-6 hours after sowing, direct seeding without germination, sowing a seed per hole, after sowing with a sieve covered with fine moist soil. After sowing, before emergence, the temperature should stay at 24-26 °C, generally 4-6 days can be out of Qi. After the seedlings are flushed, the temperature is appropriately lowered to maintain the daytime temperature of 23-25°C and nighttime at 16-18°C.
In addition, during the seedling stage to actively prevent pests and diseases, should strictly control the spraying time, spray concentration and spray frequency. The spraying time must be carried out in the evening, the droplets should be fine, the spray should be uniform, and the foliar should be covered with a fine mist, and must not be re-sprayed to prevent phytotoxicity.
Third, timely planting
1. Preparation before planting
Precisely 10-15 days before planting, it is necessary to finely prepare the soil, apply high-quality manure rich in organic compost, chicken manure, bean cake fertilizer and other high-quality fertilizers, apply 5000 kg of high-quality organic fertilizer per acre, 100 kg of diammonium, and do 70 cm and other row spacing. Large and small rows of plants, big row spacing 80cm, small row spacing 60cm.
2, colonization
Around mid-September, when the seedlings grow to two leaves and one heart can be planted, planted 3-5 days before depending on the soil moisture situation, in advance to make the earthworms. When planting, select the afternoon of sunny days, dig pits with 35cm planting distance to plant the water-seedlings. The planting process should be carried out with as many soil ridges as possible, and less root damage. Due to the shorter seedling age, the planting depth should not be too deep, and the planting area should be 2500-2800. Strains.
IV. Management after planting and before harvest
1, temperature management
External temperature during planting is still high, allowing seedlings to grow for a period of time in the open, if the noon temperature and ground temperature is too high, shade measures should be taken to cool.
2, water and fertilizer management
Watering should be controlled by pouring water to promote the main. Therefore, after planting, it was emphasized that 2-3 times of water was poured. In addition to the colonization water, the seedling water was poured every other day; the seedlings were regenerated after 7-8 days, and then the growth was resumed and water was poured once. Watering in time promoted the easing of seedlings and maintained the plant Strong growth is particularly important. If the base fertilizer is insufficient, a small amount of decomposed organic fertilizer may be applied on both sides of the planting line before the third watering, and attention may be paid to applying the available nitrogen fertilizer. After the fertilizer is applied, the soil is topped off and the next time the topdressing watering should be performed during root enlargement, depending on the situation, the soil water deficit plants need to be advanced before the roots expand, and when the water shortage is strong, the roots can be postponed to the roots. After harvesting, the top dressing is usually combined with watering to diammonium.
Fifth, take melon period management
The temperature control in the early stage should not be too high, keep 25-30°C during the day, 13-15°C during the night and 20-22°C on cloudy days. When the average temperature in the outside world drops to 12-14°C, insulation measures should be taken, such as stamping the grasshoppers. Non-woven fabrics, etc. In winter, the temperature is controlled at 23-25°C during the day and cannot exceed 28°C. The lowest temperature is 12-14°C in the morning and the temperature in the cloudy days can be appropriately reduced.
In the early stage of melon harvesting, the outside temperature was relatively high, and the water was usually watered for about 10 days. After that, it was poured once every 15 days as the temperature decreased. 1-2 water chase after a fertilizer, each time the top of the deforestation organic fertilizer 100-200kg or diammonium 10-20kg, it is best to use the two alternately, so that the quail can be maintained until the following year 2-3 months, in the melon period It should also cooperate with foliar spray fertilizer, generally can spray 0.2% potassium dihydrogen phosphate, combined with artificial spray carbon dioxide gas fertilizer.
3, hanging vine, pruning and other management
When the cucumber grows in eight or nine leaves of the plant, and the vine is about 40 centimeters in length, it begins to use a nylon rope to hang the vine and fix the vine. In terms of plant adjustment, single branching (with sticky cucumbers) and two to three branches were all pruned, that is to say, all the lateral branches below the 7th section of the plant were removed, and more than 7 branches retained 1-2 branches of lateral branches. After reaching the end of 10-12 knots, the top of the main vine is picked at 22-25 knots. In order to prevent roots from falling, if there are more root melons (more than two), one should be kept and the rest removed. In the growth and development process of some varieties of cucumbers, a section of two melons or a section of melons often appear. The performance of reproductive growth is stronger than that of vegetative growth, and the necessary fruit thinning and fruit thinning should be carried out to regulate the plants. The vegetative growth.
