Garlic is a garlic vegetable that is cold-resistant and grows 12-25°c, with long-sunseed crops. Water is suitable for easy, fertile, organically rich micro-alkali soil cultivation. The following is the main focus of garlic cultivation:
(i) choice of varieties
The main varieties currently suitable for cultivation in the tritium area are the sichuan red seven (generation, generation), the soft garlic, the first, the second and the local purple garlic。
(ii) time of seeding
The dam areas are usually premature garlic seedlings and red seven stars (generations, generations) growing on white dew (early september). The best planting period for the second stage is around the fall split (mid-september). The late delivery of garlic is appropriate from autumn to winter (i. E. From 23 september to 8 october). High-altitude areas can be cultivated by an order in advance。
(iii) seed treatment
Before seeding, the garlic is selected and graded, removed from the pest-infested garlic, divided by large and small, and planted by grade。
(iv) twilight and rationally constructed
The whole floor is made with the requirement to be thick and thick, with a surface width of 3-4 metres. The seeding should not be too deep, and the soil should be kept moist and promote early seeding. The red seven-star acres require 100-120 kg of seedage, other species are small in garlic petals, and the acreage is only 60-75 kg, with an acreage density of 30,000-40,000, 15-18 centimetres in rows, 8-10 centimetres in length, pre-cooked varieties, and late-cooked varieties。
(v) field management
Weed-cutting pine soil: if the soil is shrunk or weededed, weeding shall be combined and the first tillage shall take place when the seedling is 10-13 cm, the first tillage shall take place when there are 2-3 leaves, and the second when there are 5-6 leaves at 26-33 cm. Garlic weeding is more expensive, and chemical herbicides should be promoted to improve their efficacy: three days after garlic planting, spraying herbs with gore and grass-killing, and one or two times after seeding should prevent soil slinging and weeding. If weeds are larger, different herbicides may be selected once for different types of weed。
2. Water: when the garlic is soaked, the soil is soaked when the currents normally do not require water, and the soil should be dried up once. In early childhood, water should generally be used less, more often than not, and water should be properly controlled to prevent the premature growth and “retire mothers”. Increased water is needed to avoid drought and to keep the soil wet during periods of high graze and tubers. Water should be pumped mainly in ditches, without flooding the surfaces, and the earth's tides should be lifted to avoid flooding, and the five to seven days before the garlic harvest should be stopped, otherwise it would be easy to produce garlic。
3. Fertilizers: as garlic is long-lived and needs high levels of fertility, it should be applied to the bottom, in stages, to meet the growing needs of garlic. Garlic fertilization should be based on organic fertilizer, which accounts for 70 per cent of total fertilizer use, and the ratio of nitrogen, phosphorus and potassium: 0. 8:1 is appropriate, with an acre in the range of 12. 5 kg of pure nitrogen, with care to supplement calcium-containing fertilizers, increase the application of boron fertilizers, and use “a clean-up” or double-down early recovery methods for fertilization. The average bottom acre is 30 kg of compound fertilizer (15:15:15) with hog dung 50 - 80 loads, the defecation period (around 5 leaves after seeding) is followed by a single seedling fattening, the acre is 30 kg of urea or 35 kg of ammonium carbon, the round foot period (after 8 leaves) is 20 kg of urea or 30 kg of ammonium carbon per acre。
4 insects and diseases: during the growth of garlic, especially after december, cold tides are higher, with low oligarchy and high humidity leading to garlic pests. The main diseases are rusty, leafy, disease. Prophylactics: rustin, bacillus, trichlorfon, zhex, which can be administered at the onset or during the onset of the disease; pests with onions that can be killed with trichlorfon. Following spring, with rising temperatures and rising sunlight, garlic enters a rapid growth phase, requiring the highest amount of fat water, paying attention to the need to feed the seedlings and water in due course, while lowering the temperature of the fields to meet the demands of garlic growth。
