Summer sowing celery preservation seedlings strong seedlings technology

July is the most severe month of the year. High temperatures, strong light, heavy rain, hail and even drought are very likely. From the beginning of July to the middle of July, it is the season to prepare winter greenhouses and greenhouses for the production of celery seedlings. However, the celery seeds are small and grow slowly, and the seedling period needs 70 to 80 days. How do the delicate celery seedlings save seedlings and breed strong seedlings in this unfavorable environment? After many years of practice and earnestly summing up experiences, I believe that the following ten key tasks need to be tackled: Choosing celery from a variety of celery varieties is rare. The ribs are brittle and the petioles are generous and popular. After many years of trial planting and observation by the masses, the celery varieties that are currently adapted to the market include FS, Celery No. 3, Victory Celery, and the Statue of Liberty. To determine the seeding amount of celery seed weight of 0.4 grams, if calculated according to theory, 10,000 acres of seedlings need seed about 5 grams. However, because the celery seed is small, it will be endangered by various factors during the growth process. Therefore, it is entirely possible to increase the amount of seeds for seedlings by 8 to 10 times, and to maintain 8 to 10 seeds per seedling. Under this scenario, as long as the land is well-prepared and various protective measures are followed, planting 1 mu of celery to buy about 40 grams of seed can be sufficient. If the protection measures cannot be followed after sowing, even if the seeding rate is increased, it will be difficult to ensure the whole seedlings, and it will be more difficult to breed strong seedlings. Low-temperature germination celery likes cold, when the temperature is higher than 25 Â°C budding is very slow, more than 30 Â°C will be difficult to bud, in 15 Â°C ~ 20 Â°C under conditions of 8 to 10 days can be a smooth budding. Therefore, low temperature germination is required under high temperature conditions. Specific methods: Before germination, soak the seeds in cold water for 24 hours, rinse them out with plenty of water, rinse them until they are clear, then drain the water. Spread the seeds on the newspaper and put the seeds loose into a clean wet cloth bag. In the germination. For moisturizing, put the bag in a plastic bag. In rural areas, many seeds are hung in the well (40 to 50 centimeters away from the surface of the water) and the bag is ventilated once every 2 to 3 days. A refrigerator can put the seed bag in the refrigerator freezer (usually at about 10 Â°C), low temperature treatment 9 to 10 days, the germination rate of up to 70%. The seed buds treated with low temperature can be seeded 6 days after sowing and can be seedlings in 10 days. Seed bud celery seed germination by low temperature, but due to the different fullness of the seed, the speed of germination is also very different. In order to be able to emerge soon after sowing and the emergence of neat and consistent, can change the previous shoots, sub-mixed sowing only sowing buds do not sow seeds. Specific approach: 7 days after low temperature germination, the seeds are screened every morning with screen nets. The ungerminated seeds continue to germinate and the buds can be sown. It is also possible to wrap the budded seeds with a damp cloth and put it in a well at a low temperature for 1 to 2 days until most of the seeds have sowed after sowing. However, the waiting time should not be too long, so as to prevent it from being intertwined due to the long roots, it is difficult to broadcast uniform, and it is easy to emerge after the emergence of seedlings and seedlings. Before seeding, seedbeds should be filled with base fertilizer, which should be leveled and filled with bottom water. In order to sow the seeds, some moist sand can be added to the seed buds. The prevention and treatment of nematode nematodes has become the biggest hazard in the vegetable area. It has a long survival time in soil, and there are many kinds of harmful vegetables, especially in the summer hot season. According to the survey, if the nursery soil contains nematodes, the young root system of celery will be harmed. The celery seedlings that are harmed by nematodes grow slowly. The celery seedlings with nematodes are planted in the field, and the growth is extremely slow, and the yield will be reduced. Therefore, soil used for seedbeds can be excavated from wheat stubble. If soil from vegetable fields is used, be sure to leave the stubble roots in the soil. Then apply 10% Yishubao or 10% Kelvin 4 to 5 grams per square meter to the bed. Mix, water, leveling sowing, 40 days and then apply the above amount once. After weeding, the seed of weeding celery is small and grows slowly after emergence and has poor competitiveness with weeds. If the grass is not timely, it is prone to "grass bullying seedlings" phenomenon, and even being "eaten" by the grass. For this reason, herbicides should be sprayed on the celery in two days after sowing. According to the author's test, it is better to use 33% Shitianbu or Nongsi. Per acre seedbed medication 120 ~ 150 ml, 70 ~ 75 kg of water. When standing on the spray, the sprayer sprays the uniform spray backwards, and the foot can't step on the surface that has been closed by the liquid, so as to prevent the destruction of the film, thereby reducing the anti-grass effect. Sun protection against rain High temperatures and strong light in summer, especially with heavy rain, often make seedlings with poor resistance difficult to resist, and it is difficult to grow seedlings without any protective measures. Therefore, after sowing, a 4-meter-long bamboo culm was planted on the bed, and a 1-meter-high arch shed was placed on the bed. The shed was 2 meters wide. In order to facilitate the fall of rain, the arc of the shed should be slightly larger. The awning is covered with a shade net with an opacity ratio of 50%, or an old film with a width of 4 meters. However, a height of 50 centimeters should be set around to facilitate ventilation and cooling. Appropriate time seedlings and Dingmiao celery emergence, the cotyledon flattened when the heart leaves for the first time the seedlings, the seedlings, too thick between the seedlings, seedling spacing plus 0.5 cm. The second time the seedlings were planted 15 days later, the seedling spacing was about 1 cm. After 1 month, the seedlings were seeded and the seedling spacing was 4 cm. Each time after seedlings, root water should be poured once to compact the soil between the seedlings when the seedlings are loosened. Note that the water management celery seedling root is shallow, not drought tolerant, and not resistant to earthworms. During the nursery, moisture management should be carried out according to the weather and soil conditions to keep the surface moist and not to accumulate water after the rain. Therefore, the seedbed should be drained smoothly, and the water in the urine should be drained in a timely manner one hour after the rain. Disease prevention and treatment Diseases of celery seedlings can cause celery damping-off disease and celery blight of large dead seedlings. The occurrence of damping-off of celery is generally preceded by individual seedlings, which are laid down several days later. The celery blight frequently occurs in the middle of the nursery. It is slightly later than the damping-off disease. The seedlings in the early stages of the disease are wilted during the day and recover at night. In severe cases, the lesions spread to the base of the stem, resulting in contraction of the stems and dead on the ground but not lodging. The occurrence of both diseases is related to the robustness of the celery seedlings, and the thin weak seedlings are most susceptible to disease. Control methods: Use 50% carbendazim powder 9-10 grams per square meter seedbed before nursery, add 15 kg of fine soil and mix well with synthetic soil. Before sowing, 1/3 of the medicine soil is used as bedding, seed buds are planted on the bedding, and 2/3 of the medicine soil is used as cover soil to cover the seed buds. This kind of method of underlaying and covering can prevent diseases. In the seedbed, individual dead seedlings were found to be unplugged in time and disinfected with 75% chlorothalonil 700 times full bed spray. Seedlings can not be too thick, pay attention to ventilated ventilation, the surface should often be sprinkled with some dry fine soil (can be mixed with some carbendazim), in order to protect the disease.
