First, do a good job in the greenhouse, the middle arch shed fruit vegetables. From December last year to January this year, the tomato, cucumber, pepper, eggplant and other seedlings cultivated in the greenhouse can be planted in the greenhouse and the middle arch shed in the middle of March. When planting, you should apply more organic fertilizer and less nitrogen fertilizer. Apply more than 10 square feet of chicken manure per acre, or 15 square meters of farmyard manure. The plants are large, strong and sick, and the fruit yield will be high and the taste will be good. Second, it must be planted appropriately. It is necessary to completely change the traditional practice of "a variety of seedlings and more than one pound of fruit." Properly planted, the individual grows well, the disease is light, and the drug can be used less. Tomato and cucumber can be planted in 3200 ~ 3500 plants. Three must be planted early. Early planting can be long, but the risk is high. It is recommended to carry out multi-layer coverage after planting, so that it is prepared.
Second, strengthen the management of large-scale fruit vegetables in the greenhouse during the winter. The winter greenhouse is dominated by cucumbers, followed by tomatoes. In March, the sunshine will grow day by day, and the temperature will rise slowly. It is necessary to seize the 3 to 4 months to strengthen the water and fertilizer supply. According to different soil quality, water is poured once every 5 to 7 days, and the fertilizer is applied once every 1 hour. The chicken manure filter can be used for top dressing. It can also be used with 20 kg of urea per acre with watering. In the temperature management, for the plants that have entered the fruiting period, the sunny temperature is kept at 30 °C ~ 32 °C, the night can be lower, and the temperature difference between day and night is controlled above 15 °C. As long as the supply of fertilizer and water is sufficient and the temperature difference is increased, the plant will grow and not decline, and the result period will be extended. In addition, it is necessary to release the dust early in the evening, often wipe off the dust on the film, see more light, see strong light. By mid-March, if there is no major change in the weather, the night grass can be placed one by one, or even one by one. In the second half of March, the grass can not be placed.
Third, the onion, leek seedlings from mid-March to early April began to grow large onions, amaranth seedlings. Scallions can be selected with Yuyi green onions and Zhangqiu green onions. Amaranth uses 791, Pingyi 4 and other varieties without sleep characteristics. Watering and then spreading the seeds, spraying the herbicide after covering the soil. The herbicide can be used with 40% Napo, or 33% Shi Tianpu, 50 to 60 kg of water. Spray must be sprayed backwards to prevent the footprint from damaging the film and reducing the grass-proof effect. The nozzle should be lowered and sprayed when there is no wind to prevent the liquid from drifting and harming nearby crops.
Fourth, the cultivation of exposed watermelon seedlings The traditional method of the openland watermelon is broadcast live in late April. Although the live broadcast is labor-saving, it is difficult to get a whole seedling at a time. Nutritional alfalfa grafting should be strongly promoted. The 90A hoist is used as the rootstock, and the excellent watermelon seedling is the scion, which can be used by abutting or plugging. For the cultivation of watermelon in open field, it is necessary to choose a variety of large, high-yield, easy-to-eat melons, such as Taiwan Heibao, Moyu No. 2, Yuyi New No. 1, Kaiza No. 2, Zheng Kang No. 3, Zheng Kang No. 4, etc. The seedbed adopts a variety of covering forms such as a small arch shed in the greenhouse to ensure that the whole seedlings are planted and the seedlings are bred.
5. Yuxi gourd and cucumber seedlings In early March, a batch of cucumber and zucchini seedlings cultivated in a short period of time were cultivated. Seedling age 25 to 30 days, planted at the end of March or early April. Covered for 15 days after planting. Although the coverage time is short, the seedlings are fast and the roots are good, which lays a foundation for early maturity and high yield. Cucumber can be selected from Jinlu No. 4, Jinyou No. 4, and Yucui No. 2, and the western cucurbits are selected from Adonis, Early Green, and White Jade.
6. Solanum and fruit vegetable seedlings The eggplant vegetable seedlings cultivated in the greenhouse and hotbed at the beginning of January to February have grown to 2 leaves and 1 heart. At this time, they should be divided into 10 cm squares to the middle arch shed, or multi-layer covered greenhouse. In the end, continue to cultivate for cultivation after exposure to frost.
7. Sowing some fast-growing leafy vegetables Use the winter idle land to sow some fast-growing cold-tolerant leafy vegetables, such as alfalfa, Shanghai green, spinach, and oily wheat. It can be broadcasted and covered with a film for several days after sowing. These leafy vegetables were marketed more than 40 days after sowing.
Eight, double film cover sowing spring cabbage, spring radish, spring carrots Chinese cabbage selection of Chinese cabbage 1l and other resistance to smoking. It adopts small high ridges, one ridge and two rows, and the mulch film is covered after sowing, and the arch shed is covered, and 3000 plants per mu are protected. Pay attention to ventilation in April, the shed temperature is not higher than 25 °C, and harvested in mid-May. The radish uses spring-type varieties such as Fuchun Dagen and Lichun Dagen. The method is the same as cabbage, but about 4000 plants per mu. Spring carrots can be used in straight three red, black field 5 inch and other varieties. Short-term film coverage is required for planting in early March. If it is not covered, it can be planted in the flat from the end of March to the beginning of April.
IX. Pest Control In March, pests and diseases were mainly concentrated in greenhouses, greenhouses and other protected areas. Cucumber has downy mildew, anthracnose, blight, gray mold, etc. Tomato has gray mold, leaf mold, early blight, late blight, spot blotch, zucchini mainly has gray mold, powdery mildew, etc., eggplant and pepper There are diseases such as diseases. In addition to strengthening ventilation and reducing humidity, these diseases can be selected from the group consisting of chlorpyrifos, carbendazim, chlorothalonil, chlorpyrifos, kelu and biocide Trik. The pests mainly include aphids and whitefly. It is necessary to install insect-proof nets in the vents of greenhouses and greenhouses, and then close them. Use dichlorvos and anti-smoke to kill them. It can also be sprayed with lesbian, poisonous, and insects.
In addition, the seedlings are sprayed once with insecticides and fungicides on the seedbed before planting.
Second, strengthen the management of large-scale fruit vegetables in the greenhouse during the winter. The winter greenhouse is dominated by cucumbers, followed by tomatoes.
