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 1.2 to 1.5 meters is appropriate.
Sowing seedlings
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 first soaked 4 to 6 hours, without direct germination sowing, sowing a seed per hole, after sowing with a sieve covered with fine soil. After sowing, before emergence, the temperature of day and night should be maintained 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.
Timely colonization
1.Preparation before planting: 10 to 15 days before planting, make a fine land preparation, apply high-quality organic manure-rich compost chicken manure, bean cake fertilizer and other high-quality fertilizers, apply 5000 kg of organic fertilizer per acre, diammonium 100 kg, and press 70 cm. Line spacing can also be used to plant large and small rows, with a large row spacing of 80cm and a small row spacing of 60cm.
2. Colonization: Before and after mid-September, when the seedlings grow up to two leaves and one heart can be planted, planting 3 to 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 and water the seedlings. The planting process should be carried out with as many soil ridges as possible and less root damage. Because the seedling age is shorter, the planting depth should not be too deep, and the planting area is 2500-2800. Strains.
Management after planting and before harvest
1. Temperature management: When the outside temperature is high when planting, it can allow the seedlings to grow for a period of time in the open ground. If the temperature and the ground temperature at noon are too high, shady cooling measures should be taken.
2. Water and Fertilizer Management: Watering should be controlled by pouring small water to promote the main. Therefore, after planting, we emphasize pouring 2 to 3 times of water. In addition to planting water, we will plant the seedling water every other day; 7 to 8 days will be completed and the seedlings will be regenerated, then the growth will be resumed and water will be poured once. Watering in time will promote the easing of seedlings and maintain 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.
3. Hang vines, pruning and other management: cucumber in the plant eight or nine leaves, stems around 40 centimeters, began to use nylon rope hanging vines, fixed vine. In terms of plant adjustment, individual vine pruning (with sticky cucumber) and two to three vine pruning, 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 2 larvae of strong side branches, when the side branches were melons After reaching 10 to 12 knots, the tip of the 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.
Harvesting period management
The temperature control in the early stage should not be too high, maintain 25~30°C during the day, 13~15°C during the night, 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 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 the next morning, and the temperature can be reduced appropriately when it is cloudy.
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. Every time 1 to 2 water chase a fertilizer, every time, Mu applied organic fertilizer 100~200kg or diammonium 10~20kg, it is better to use the two alternately, so that the melon can be kept until the following year 2~3 months, in the period of melon It should also cooperate with foliar spray fertilizer, generally can spray 0.2% potassium dihydrogen phosphate, combined with artificial spray carbon dioxide gas fertilizer.
