Spring has arrived, and many crops have reached the greening stage. Recently, the growth rate of garlic is also accelerating. We must do the spring management of garlic to ensure the yield and quality of garlic. So how should the spring garlic returning to the green period be managed? First, the protection of temperature increase When garlic enters the greening period, the garlic and garlic begin to differentiate. The key to the management of the greening period is to increase the ground temperature to promote the growth of the root system. It can be covered with straw to increase the ground temperature and promote the early return of garlic. For the garlic grown on the mulch film, the dust and diseased leaves on the mulch film should be removed early to purify the membrane surface to increase the transparency and increase the ground temperature. Second, antifreeze and cold resistance In the greening period of garlic, if it is cold or cold, it will cause the plants to freeze and affect the normal growth of garlic. Therefore, it can be sprayed with Guoguang Power (S-Elicitin) + Luokang water to 1-2 days before the cold spring, to improve the anti-freeze and cold resistance of garlic and reduce the damage caused by low temperature on garlic. Third, promote roots and strong seedlings After mid-February, the temperature gradually rose, the garlic plants began to grow, the garlic cloves rotted, the plants grew new adventitious roots, and the growth accelerated. At this time, attention should be paid to the curing of garlic roots, promote the root growth of garlic, and improve the absorption capacity of roots for nutrients and water to promote the rapid growth of garlic plants. It is recommended to use Guoguanggenbao+Guibaobao+Youfengfu water for foliar application to promote the growth of garlic roots. Fourth, remove weeds Warmer temperatures are conducive to the growth of weeds, weeds grow too fast, will compete for soil nutrients, and seriously affect the growth of garlic. The weeds can be removed, or the taro can be used to gently weed the plants between the rows of garlic to reduce weeds, and at the same time enhance the permeability of the soil and facilitate the growth of the roots. Five, fertilizer and water management In early spring, the temperature rises and the roots start to move. Good fertilizer and water management is the key to promoting the growth of garlic. Fertilization and watering of garlic depends on soil moisture and flexibility. Under normal circumstances, when the ground temperature reaches 15 degrees or more, watering and fertilization can be carried out at noon, and with the return of Qingshui, Guoguang Shiyou (12-10-28) or Songer Fertilizer (25-5-15) can be added. The nutrients needed for garlic promote the growth of garlic and accelerate the return of garlic. At the same time, it is used for garlic twitching and garlic swell to store nutrients. Note: After irrigation, it is necessary to cultivate in time to prevent soil compaction and affect root growth. Generally, it is necessary to cultivate the loose soil 1-2 times to increase the ground temperature and protect the roots. In case of drought, water can be re-watered once. If the leaves appear dry yellow leaves, it is necessary to carry out top dressing in time, and do a good job of prevention and control of gray mold and leaf blight. Sixth, disease prevention Leaf blight and gray mold are common diseases of spring garlic. In the early stage of leaf blight, the white tip of the garlic leaves appeared or the pale brown oval-shaped lesion appeared on the surface of the leaf. When the disease occurred seriously, the leaves died, the base rotted, and the garlic plant fell. In the early stage of the disease, it can be controlled by Guoguang Enda 600-800 times + 300-500 times of total spermamine spray. In the early stage of gray mold, the leaves of garlic seedlings have chlorotic white spots on both sides, and then expand into the shape of growth or spindle-shaped spots, which are extended downward by the tip of the leaves, causing most of the leaves to be half-yellow. When the humidity is high, gray mold layers are formed, resulting in leaves. Brown or watery rot. In the early stage of the disease, it is recommended to use the Guoguang Pythium 600-800 times or Guoguang Haozhuang 1000-1500 whole plant spray for prevention and treatment. Note: It is strictly forbidden to pour back into the Qingshui water in the case of serious diseases. It will delay the watering time depending on the weather and sensation, and provide a good environment for the regeneration of garlic roots and cultivate robust plants. Tips: Due to the variety of garlic varieties, different climatic conditions, growth environment and cultivation management methods, it will have certain impact on the cultivation and management of garlic. The management points, operation methods and specific use of the above-mentioned pharmaceutical fertilizers are for reference only. When planting garlic, it must be flexibly adjusted according to the actual situation of the field. The above is all the contents of today. The medicines mentioned in the article are not recommended. The management of garlic back to green is very important. Watering and fertilizing, weeding and disease prevention, and promoting root freezing are all important tasks in the management of garlic. We must master it. The management point of garlic in the greening period, so that garlic can grow robustly.
