大蒜的种植技术(The planting technique of garlic)
Selection of varieties of Garlic Germplasm resources are very rich in China, North and South are well-known specialty area, the formation of fine varieties in many places, such as Chengdu, Cangshan two water early garlic, Songcheng white garlic, garlic, garlic, garlic bolt of Sichuan, according to local planting habits, purpose and varieties of production.
Soil preparation, fertilization, fine soil preparation, soil fragmentation should be done, the ground flat. The soil should be deep plowing about 2 centimeters, and combine soil preparation to control the soil pH value around 5.5-0.6. Over acid, the root end becomes coarse, stop prolonging growth, and over alkali, the kind of valve is easy to rot, poor growth. Garlic hi NPK total organic fertilizer, it advocates the \fertilization method, nitrogen 2/3 as basic fertilizer, the amount of fertilizer, ensure good seedling emergence, prevent premature aging, organic fertilizer to maturity, buried in the soil, especially the cake, sprinkle on the surface it will lead to the production of garlic root Vermicule, the plastic film mulching cultivation, in no fertilizer, so during the growth of garlic, with enough base fertilizer in the best preparation time before sowing, application of compost quality manure 6000 kg per mu, rotten cake 80 kg, 50 kg urea, calcium magnesium
phosphate fertilizer 80 kg, 25 kg of potassium sulfate compound fertilizer, sulfuric acid 1.5 kilograms of zinc. The high ridge furrow wow, high 8 cm -12 cm, bottom width 100 cm, width 70 cm, width 20 cm -30 cm.
Determine the planting season, according to the requirements of garlic production purpose and garlic in different growth period on the external conditions, as well as the regional climate conditions, generally north to 35 degrees - 38 degrees north latitude as the dividing line of spring and autumn. 35 degrees south area in winter is not so cold in winter, seedlings, the summer harvest in autumn, mainly including Henan, Shandong, Shaanxi Province, Shanxi Guanzhong and southern and Southern Hebei around. 38 degrees north of the region, winter cold, seedling is not easy winter, should be planted in the early spring, the summer solstice harvest. It mainly includes the northeast provinces, Inner Mongolia, Gansu, Xinjiang, Northern Shaanxi, Shanxi and Northern Hebei. Between 35 - 38, spring and autumn can be planted, such as Yubei area etc.. The length of garlic growth period varies greatly with sowing date and variety. Spring sowing garlic growth cycle is short, generally 90 days -110 days, garlic growth cycle is longer, usually 220 days -280 days. Select suitable planting season harvest is key, large size, large selection of garlic garlic hard, neat, no injury, no spots, white color and fresh garlic seed. General requirements for garlic 100 grain weight of 400 pounds or more, before sowing to 50% carbendazim WP 500 times liquid soak 12 hours -16 hours, prevent the occurrence of
fungal diseases. The garlic planting in early September to early October is appropriate, \October the temperature of 16 degrees, 5 cm ground temperature to 18 DEG -19 DEG, the winter when the garlic bolt height up to 25 cm, is conducive to the safety of winter.
The garlic planting, to 20 cm spaced 10 cm deep sowing ditch, and a small amount of fertilizer applicator, planting will valve by valve flap in 10 -15 cm, 9 cm -10 cm, 7 cm row spacing
small flap in the ditch, and keep it upright, flap back parallel to the planting row (after seedling leaf to have consistent, Litong scenery, increase the output), then cover 3 cm of soil, water, moisture while spraying herbicide acetochlor, and then covered. Film mulch, plastic film in the belt on the surface of the flat and no wrinkles, plastic film below the gap, so that the film close to the border surface, so as not to breed weeds. Sow \per mu million lines, both benefit and benefit management, high yield, can effectively inhibit occurrence of pests.
The field management of general garlic after sowing 7 -10 days after seedling emergence, Qi water second times, before soil freezing (snow before freezing water irrigated 1 times). After a few days of straw mulching, cold and drought, excessive cold can be set up to ensure safety of winter wind, garlic bolt. In mid March the timely removal of cover and grass sunny and warm weather water, with water Topdressing Urea 15 kg -20 kg, promote early growth green garlic bolt.
