High-yield cultivation techniques of garlic How to fertilize and water the garlic? Garlic is not called garlic, garlic head, garlic, glutinous rice, garlic, garlic, etc. It is the collective name of garlic plants. Liliaceae is a semi-annual herb. The optimum period for sowing is to make the plants grow to 5 before wintering. ~6 leaves, at this time the plant has the strongest cold resistance, it will not be frozen to death in the cold winter, and lay a good foundation for the plant to pass the vernalization smoothly. Let's take a look at the autumn sowing garlic cultivation technology! The optimum period for sowing garlic in time is to make the plants grow to 5-6 leaves before wintering. At this time, the plants have the strongest cold resistance, and they are not frozen to death in the cold winter, and lay a good foundation for the plants to pass vernalization smoothly. The Yangtze River Basin and its south areas are generally planted in the middle and late September. The weather in the Yangtze River Basin was cool in September and was suitable for the emergence and growth of garlic seedlings. If the seeding is too early, the seedlings grow too much before wintering and consume nutrients, then reduce the wintering ability, and may also be vernalized to cause secondary growth. In the second year, the complex garlic is formed to reduce the quality of garlic. When the seeding is too late, the seedlings are small, the tissue is tender, the roots are weak, the accumulated nutrients are less, the cold resistance is lower, and more deaths occur during the winter. Therefore, garlic must strictly control the sowing date. Reasonable dense planting is the basis for increased production. The yield of garlic and garlic is composed of the number of plants per acre, the number of garlic per plant, the weight of the stalk, and the weight of the stalk. Appropriate close planting should be done according to the characteristics of the variety, so that there are more plants per acre. Early-maturing varieties generally have shorter plants, fewer leaves, shorter growth period, and correspondingly larger density. It is better to plant about 50,000 plants per mu, with a row spacing of 14 to 17 cm, a plant spacing of 7 to 8 cm, and a variety of 150 species. ~200 kg. The mid-late maturing varieties have long growth period, tall plants, more leaves, and correspondingly smaller densities, so that the group structure is reasonable to make full use of light energy. Density should be mastered in 40 acres of acres of planting, row spacing 16 ~ 18 cm, plant spacing of about 10 cm, about 150 kg of acres. The sowing method "deep planting onions and shallow garlic" is the experience gained by farmers for many years. Garlic sowing is generally suitable for a depth of 3 to 4 cm. There are two methods of sowing garlic. One is to insert seeds, and the seed petals are inserted into the soil, and the soil is covered after sowing. The second is to ditch the seeding, that is, to open a shallow ditch with a steamed bun, and to plant the seed petals in the soil. After opening a ditch, the soil that was simultaneously opened over the previous row of petals. After sowing, the thickness of the soil is about 2 cm, and the feet are lightly soiled and watered. To prevent drought, cover the soil with two layers of straw or other moisturizing material. Planting should not be too deep, too late, the emergence of seedlings late, the pseudo stem is too long, the roots are more absorbent, the growth is too strong, the formation of garlic is difficult to expand by soil extrusion. However, planting should not be too shallow. If it is too shallow, it will be easy to "jump the petals" when it emerges. The roots of the seedlings are prone to water shortage, the roots are poorly developed, and they are susceptible to freezing death during winter. The cultivating and weeding can spray the herbicide before sowing to emergence. It is effective to control the crabgrass, gray ash, cockroach, and foxtail, and 50% of the grass is used in 100-150 grams. West Majin and Atrazine are used in 120-240 grams. Weeding through the acres of medicine 35 ~ 6S grams. For garlic fields dominated by monocotyledonous weeds, 120-150 grams per acre is diluted with 5 to 7 days after sowing (before emergence) with 30-50 kg of water, and sprayed at night. Garlic field dominated by dicotyledonous broadleaf grass, using 25% oxacillin 120-150 ml per acre, or 24 to 60 ml of 24% fruit, 7-10 days after sowing (before emergence) 40-60 Kilograms, spray at night. In the growing season of garlic seedlings, when the weeds are just sprouted, the weeds are removed, and the weeds are removed. The weeds that are difficult to cultivate between the plants should be removed early so as not to compete with the garlic. Although there is a kind of petal nutrition in the growth period of garlic seedlings in the top dressing, in order to promote the growth of the seedlings and increase the nutrient area of ​​the plants, the topdressing should still be applied. Because garlic roots have weak ability to absorb water and fertilizer, the topdressing should be applied with quick-acting fertilizer to avoid yellowing of the tip of the leaves, and the garlic topdressing is generally 3 to 4 times. Topdressing should be carried out before harvesting garlic. When the garlic is harvested, it has rich nutrients to promote the expansion of the garlic. If topdressing is carried out after harvesting garlic, it will easily lead to reduced production of greed. If the field is fatter and the garlic leaves are thicker, the fertilizer may not be applied. Due to the late twitching, the medium- and late-maturing varieties have a higher temperature. After harvesting, the garlic is usually collected for about 20 to 25 days, so it is also possible to avoid the swelling of the fat. Water management Harvest at the right time 1. Harvesting garlic For the main purpose of harvesting garlic, such as Cangshan garlic should try to keep the fake stem intact and promote the growth of garlic. When picking, the left hand usually punctures the pseudo stem at the 3~4 leaves, and the right hand pulls out the garlic. Although the method has a slightly lower yield of garlic, the pseudo stem is lightly damaged, and the plant remains in an upright state, which is conducive to the expansion of the garlic. 2, harvesting garlic: 15 to 20 days after the garlic is collected (mostly 18 days) can receive garlic. The sign of timely harvesting of garlic is that the leaves are mostly dry, the upper leaves are faded to gray-green, the tips of the leaves are drooping, the pseudo-stalks are in a soft state, and the garlic is basically grown. The collection is too late, the garlic is tender and the water is too much, the organization is not full, not full, and it is easy to dry after storage. The collection is too late, the garlic is easy to scatter, and the garlic stalks are easy to scatter when the garlic is pulled, losing the value of the commodity. When collecting garlic, use it hard to dig and gently pull it out by hand. After the garlic is shipped to the field, the last row of garlic leaves are placed on the head of the front row, only drying, not drying the head, preventing the garlic from burning or turning green. After 2 to 3 days of frequent flipping, the stems and leaves are dry and can be stored.
