How to grow garlic well?

How to grow garlic is effective? Please help me introduce the following autumn sowing cultivation methods most commonly used in southern China as an example, a brief description of various cultivation techniques. 4.1 the work of soil preparation and fertilization before sowing with base fertilizer is basically similar to that of Yanghui. To avoid continuous cropping, the sandy loam with fertile and well-drained soil is suitable. 4.2 garlic was sown directly with garlic cloves. For autumn sowing garlic cultivation, most parts of the south are sown from September to October in autumn, garlic bolts are harvested from April to May, and garlic is harvested in June. For the purpose of cultivation of green garlic, sowing can start in July, but the early sowing garlic needs to be treated with low temperature in order to break dormancy. Garlic cloves should be selected and graded before sowing. Strict selection should start before harvesting in the field, especially to remove plants with the virus. After harvest, choose garlic with variety characteristics, round head, large and harmless garlic. In order to break dormancy and promote germination, garlic cloves can be peeled before sowing or soaked in water for 1 to 2 days before sowing, so as to facilitate the exchange of water and gas. In addition, garlic cloves can germinate much earlier if they are treated at a low temperature of 0: 4 ℃ (cold storage or ice cubes can be used in production) for one month. These methods are especially suitable for the cultivation of green garlic, so that they can be sowed and supplied earlier. Sowing density and sowing rate sowing method is to insert garlic cloves into the soil, while slightly exposed tip, should not be too deep. When harvesting garlic, the row spacing is 15~20cm × 10~13cm, or denser. Sowing quantity 750~2000kg per hm2. The larger the plant spacing is, the greater the single bulb weight is, but the abnormal bulbs are easy to occur. For the cultivation purpose of harvesting green garlic, the sowing density is relatively dense, and the row spacing is 12cm × 4~7cm. 4.3 Field management when 3~6cm is unearthed from seedlings, topdressing should be started, mainly nitrogen fertilizer. During the growth period of green garlic, topdressing should be applied for 2 or 3 times from August to September to November to December to promote aboveground growth. The greater the aboveground growth, the higher the yield. For the cultivation purpose of harvesting garlic, topdressing was applied once more before overwintering, in addition to topdressing at the seedling stage. After the warmth of spring in the second year, it is the peak period of garlic plant growth, and heavy fertilizer should be applied once. Garlic began to expand, should not be fertilized too much, too thick, so as not to cause bulb rot. To promote the development of garlic, in order to achieve high yield, it is necessary to have a larger leaf area at the beginning of bulb formation. Intertillage weeding is especially important after garlic seedlings are unearthed. When the seedlings are high and 10~15cm, the intertillage can be deeper, while when the seedlings are above 30cm, the intertillage is shallower. In general, ploughing and watering are combined with fertilization. But to the next year from April to May, the bulb has begun to expand, when there are many Rain Water, should pay attention to drainage, otherwise it is easy to cause garlic cloves to spread. If too much nitrogen fertilizer is applied, the young buds of new garlic cloves may regenerate leaves, thus affecting the quality and storability of garlic. Some recent experiments have shown that the use of chemical herbicides such as herbicide, trifluralin, simazine (Simazine), atrazine (Atrizine), combined with colored film mulching has a better weed control effect. 4.4 the bulbs, leaves and bolts of garlic harvested can be used as food. Due to the different parts of food harvested, the periods and methods of harvesting are also different. Green garlic can be harvested from October of that year to spring of next year after sowing in July-August along the Yangtze River with tender leaves and pseudostems as edible. However, after entering the summer, the tissue of the leaves gradually aged and the fiber content increased, so it was no longer eaten as garlic. The vast majority of harvesting methods are uprooted at a time. However, the 3cm of the plant can also be harvested once at the base of the pseudostem and off the ground before winter. After harvest, the management of fertilizer and water should be strengthened, and the new leaves can be harvested again in February to March of the second year. The harvest of garlic bolts is closely related to the harvest of garlic bolts. Generally speaking, those with garlic bolts have split garlic heads, but those with garlic heads do not necessarily have garlic bolts. The differentiation period of young buds of garlic bolts and cloves is almost at the same time, garlic is not harvested until it is ripe, but after garlic shoot differentiation, it elongates very quickly and needs to be harvested in time, otherwise it will affect the yield of garlic. Garlic can be harvested 20-30 days after garlic stalk is harvested. If garlic bolts are not harvested, the garlic will also expand, but the yield will be reduced by more than 15%. The harvest season is also the season for more Rain Water. If the garlic is not harvested too late, the garlic is easy to rot, and it is easy to spread out after harvest, so it is not resistant to storage.
