First, variety selection, disease resistance and high yield
Due to the supply of hotels and restaurants, fruit cucumbers are more stringent. To select heat-resistant, disease-resistant, melon-striped, short (less than 15 cm), dark green imported varieties, this is the premise and basis for achieving high quality and efficiency.
Second, the soil disinfection, high temperature stuffy shed
Combining with Shi Jianfei, Mu thrown 2-2.5 kg into the enemy and then farmland. After the arable land, all the vents in the greenhouse were closed tightly and the greenhouse was sterilized for 10-15 days.
Three, precision seeding, mulching root seedlings
Due to the high price of fruit-based cucumber seeds, high-quality nutritional substrate plugs are used for seedling production. Seeds can also be sterilized before sowing, commonly used warm soup soaking seed method, that is, the seeds immersed in 55 °C hot water (according to boiling water 2: cold water 1 volume ratio hook) and constantly stirring, keep the water temperature for 15 minutes, then you can make The water temperature naturally drops to room temperature, soaking for 4-6 hours, removing the seeds, draining the excess water, and preparing for sowing. Can also be used to soak seed, commonly used drugs are carbendazim (500 times liquid), potassium permanganate (1000 times liquid) and so on. Disinfect the seed with the agent to strictly grasp the concentration of the agent and the soaking time, such as 50% carbendazim 500 times, soaking time does not exceed 30 minutes. In the process of soaking seeds, it is necessary to continuously stir the seeds. After the chemicals are disinfected, they should be washed repeatedly with clean water. If it is a coated seed, it is not necessary to carry out the above seed treatment and direct sowing, pay attention to the seedling tray after seeding to pour enough water, keep the cover soil moist before emergence, which will help the emergence of seedlings.
Attention should be paid to five points in the precision seeding: firstly, the seeds should be laid flat; secondly, the thickness of the cover soil should be 1.5-2 cm; it should not be too thin to prevent the cap from being unearthed; and the third time is that after the June 20 seeding time, the local corn field will be missed. Herbicide time; Fourth, hot weather, greenhouse temperature exceeds 35 °C, before and after noon with a shade net cooling; Fifth, nursery attention to the prevention of seedling disease, nurturing strong seedlings.
Fourth, high ridge cultivation, ventilation and rain
Select the former to be soil and fertile soil such as beans and onions and garlic. It is best not to make continuous series with melons. If you can't open the mouthwash, you need to use anti-strengthening agent. One-time basal fertilization before soil preparation, applying more than 5,000 kilograms of fully-fertilized organic fertilizer per acre. For soil compacted plots, proper amount of bio-organic fertilizer can be applied to improve soil microbial status. Make a small stilt with a height of 15 cm and a width of 70 cm, cover with a black mulch, and leave 80 cm of work lanes. For each row of 2 rows, the density of mu is no more than 2000 trees, and the planting is easy to use for ventilation and light transmission to reduce the occurrence of diseases.
Fifth, special pruning, balanced growth
According to the characteristics of fruit cucumbers, such as main cranberries, we use special pruning techniques. The total number of lateral vines below the main vine 6 leaves was removed. The side vines with more than 6 leaves left 3 leaf topping and the vines grown with lateral vines also left 1 leaf topping to improve early yield and total production. After the fruit is full of cucumbers, remove the top and remove the lower disease and old yellow leaves. Due to the high temperature in summer, the humidity in the rainy season is high and the temperature is hot and stuffy. The pruning must be kept in order to facilitate the ventilation of the fields and reduce the diseases caused by high temperature and humidity.
Six, timely ventilation, rain and disease prevention
The cultivation of fruit cucumbers in summer and ventilation in time is the key. To do so, open all the air outlets on rainy days and close them in a rainy manner in time to prevent rainwater from entering the shed and causing diseases.
Seven, watering is reasonable, less fertilization
After 5-7 days of colonization, when the heart leaves begin to grow, when the underground minister produces a large number of new roots, pour a gentle seedling water, promote root growth, and then do not water the roots before sitting on the roots, carry out the cultivator seedlings, and force the roots to descend. When the root melon began to enlarge, the seedlings should be ended and the fruit water should be poured in time. The cucumber roots of the fruit are shallow, and the squash should be enhanced with fertilizer and water management to keep the soil moist. Avoid flooding and flooding with small water. Watering should be done before picking the cranberries. No watering can be done at noon. Fertilizer should be applied sparingly, at the end of the seedlings, combined with watering to chase a fertilizer, and then every time after pouring 1 to 2 times of water to recover a fertilizer, the top dressing should be mastered a small number of times, each time applying 10 to 15 kg of compound fertilizer per acre. Foliar spray can also be used to promote the growth of cucumber.
Eight, pest control, prevention
After the planting of the cucumbers, we must pay attention to the prevention of diseases. At this time, high temperature and rainy season, the ventilation of the greenhouse is not good, the planting seedlings are vulnerable, and the disease resistance is poor. The late-night temperature difference between day and night increased, fruit cucumber due to lush foliage, if the ventilation is not good, can easily cause the occurrence of downy mildew, so every 7-10 days to spray 72% DuPont Kelu 800 times fluid, 25% metalaxyl Manganese zinc and other agents to prevent the occurrence of diseases.
For insect pest prevention, pest control nets were added at the entrance and outlet of the greenhouses to physically isolate them; using the characteristics of locusts, whiteflies, and spotted flies to strongly shade yellow, yellow sticky boards were hung in the canopies to achieve The purpose of pest control. If necessary, take chemical control, Liriomyza with 2% avermectin 3000 ~ 4000 times liquid; whitefly can be used 10% buprofezin 1000 times; aphid can be used 10% imidacloprid 1500 times spray control. Pest control spraying 10 to 15 days 1, the general election sunny and windless weather, when the temperature is high, the pharmaceutical concentration should be appropriately reduced. To prevent and treat pests and diseases, one type of pesticide should not be used multiple times, and multiple agents should be used interchangeably to prevent drug resistance and reduce the use of pesticides.
