1. Selection of improved varieties: Improved varieties are an important condition for high yield and high efficiency. Since the performance of “Hanzhong Dongluo†and “791†in the county in 1998, the area has increased significantly, and its area has been expanding year by year, and the economic benefits have been significantly improved. The winter of 96-99 has been significant. There were 0.48, 0.85, 1.15, and 13800 mu of total cultivated area for Hanzhong winter glutinous and 791 in greenhouses, respectively, which totaled 38,600 mu, accounting for 88.7% of the area that should be promoted in the same period, of which the promotion rate in 1998 was 95.8%. 99 years of promotion rate of 100%.
2, site selection: should choose fertile soil, deep plowing layer, convenient drainage and irrigation of the plot as a site, the first year of species of Chinese amaranth to deep plowing before the winter, the following spring replanting high-quality organic fertilizer, generally Mushi 80 -100 lbs, intensive cultivation, flat work.
3, appropriate sowing: shed planted leeks 4-5 years for seedlings, I suitable sowing period in the end of March to early April, the general spacing 20 cm, ditch depth 7-10 cm, groove width 6-10 cm, ditch After the seedlings are sowed, the seeds are sown after lack of lyrical crops, about 4 kg per mu, and 1-1.5 cm soil after sowing, and then they are applied to the surface of the mulberry seedlings. The mulching film has functions of increasing temperature, keeping pods, promoting germination, and maintaining seedlings. After 10 days of general sowing, seedlings are planted, and the film is removed after emergence. After the film is uncovered, fertilization, watering, loose soil, and weeding are performed according to soil moisture conditions.
4. Management of greenhouses: Greenhouses are generally constructed of bamboo and wooden structures, with a width of 6 meters and a length of 30-50 meters. The management of greenhouses should pay attention to the following points: (1) Clean gardens, fertilization, pest control, cover soil, irrigation, and disease prevention. 1 Clear Garden: Around December 10th, all the ground parts will die. The nutrients in the leaves of the leeks can be removed after the roots are returned to the roots. Fertilizer, pests, and irrigation are then applied immediately after the clear garden; 2 Fertilization: 50 kg of urea per mus. Calcium phosphate 100 kilograms, chemical fertilizers should be applied to deepen the ditch; 3 pest control: 75% phoxim 0.5 kg watered 30-40 kilograms of fertilizer is used to prevent and control underground pests such as earthworms and earthworms after the application of chemical fertilizers. The second time after the leek is unearthed, Phoxim spray control; 4 covered nutrient soil: nutrient soil thickness is controlled at 5-6 cm, nutrient soil is generally used in the high-temperature season with garden soil plus 30% of household miscellaneous fertilizers mixed and stacked, fertilizer pond dried and crushed is also One of the high-quality nutritive soil raw materials; 5 irrigation: Foot water is one of the high-yielding links of shed planted leeks, after the nutrition soil covers, it needs to be filled with water, and it is generally based on barrage irrigation; 6 disease prevention: disease of leeks with gray mold is The main method of prevention and control is to use 50% carbendazim 250 grams watered 30 kg spray per mu after harvesting. (2) Shedage time: Shed shed for 3-5 days after leeching, and the daylight temperature is controlled at 20-25°C during nighttime and not lower than 6°C at night. (3) Harvesting: The first leek was listed 45 days after the shed, this time coincides with the sales peak of the Spring Festival, and the price is higher. It is the key to high yield and high efficiency in greenhouses. After that, every 25 days will be cut and the total period will be 4 So far. Shed leeks only harvest 4 times a year in the spring, spring - autumn should strengthen management, root protection leaves, savings nutrients, should not be re-listed, spring - autumn management should pay attention to 2 points: 1, leeches for more than two years is strictly prohibited Flowering and knotting can be reduced by taking tender flowers and other methods to reduce nutrient consumption. 2, to prevent lodging and rot: For the more prosperous leeks, cut one-third to one-half of the leaves, can effectively control the amaranth lodging and rot.
