How to manage the garlic convulsion period?
In March, the whole country entered the convulsion period. This is the stage of symbiosis between garlic and garlic. It is also the stage of vegetative growth and reproductive growth. At this time, the amount of fertilizer needed is large, so the growers should do the management of the garlic pumping period. If the nutrients are not replenished in time during this important growth phase, the garlic will be twitched slowly and the garlic will be weak. At the same time, with the increase of temperature, the rainfall increased, and the pests such as cockroaches and thrips that survived in the soil began to be active. The leaf blight of garlic also began to break out. If it is not timely, it will affect the convulsion of garlic and the enlargement of garlic cloves. . Therefore, the management of garlic convulsions is directly related to the yield of garlic and garlic. 1, reasonable watering When garlic enters the twitching stage, flower buds and buds rapidly differentiate, and gradually enter the garlic stalk and garlic growth and advance. At this time, the leaf area reaches the maximum, the root system also extends to the maximum range, and the garlic stalk grows rapidly, which is the period of maximum water demand. When water is scarce, it will hinder the growth of the plant, and the unevenness of the garlic can be uneven. When picking, the problem will be difficult to break due to "tightness". Therefore, it is necessary to water the pumping water in time. After the “now tailâ€, it should be continuously watered. Generally, it should be watered once every 5-7 days to achieve the purpose of promoting water seedlings by water. The water should be stopped 2-3 days before the harvesting, and the shallow soil will make the plants slightly wilted. So that the "mouth loose" is easy to pick. Pay attention to the protection of the leaves and roots during convulsions, prevent premature senescence of the leaves, reduce the production of organic nutrients, and hinder the expansion of the bulbs. 2. Re-application of phosphorus and potassium fertilizer After the garlic is smashed, the flower buds and buds gradually differentiate into the flower stem elongation period. In this period, the old roots of aging roots occur in large quantities, while the stems and leaves and garlic stalks also rapidly elongate, and the garlic begins to slowly expand. The sufficient phosphate and potassium fertilizer can promote the growth of garlic and garlic stalks, so it should be applied quickly and efficiently. Types of phosphorus and potassium fertilizers to improve the quality and yield of garlic. It is recommended to use compound fertilizer or organic fertilizer to meet the nutritional needs of garlic, and promote the rapid growth of garlic. 3, remove weeds The warming of the temperature in March is conducive to the growth of weeds. Weeds grow too fast and compete with garlic for water, water, and nutrients. As a result, garlic is small and scattered due to lack of nutrients. The main areas of the garlic field are broadleaf and monocot. Weeds are mainly weeds, weeds can be removed during the management process, and weeds can be used to carry out shallow weeding between the rows of garlic to enhance the permeability of the soil and facilitate the growth of roots. Note: At this time, the herbicide can not be used for field weeding, so as to prevent the herbicide from floating on the leaves and stems of the garlic, causing the leaves to die. 4. Reasonable use of plant conditioner The development temperature of garlic stems and bulbs is 15-20 °C. When the temperature exceeds 26 °C, the plants are physiologically dysfunctional, the stems and leaves are gradually dry, and the growth of underground bulbs tends to stop. At this time, foliar spray plant growth regulator (S-excitation) + foliar fertilizer water, adjust the opening and closing of leaf stomata, reduce water transpiration, improve the drought resistance of garlic, reduce high temperature, drought on garlic Damage caused. 5. Pest control Leaf blight occurs more frequently during the convulsion period of garlic. In the early stage of leaf blight, there are white dots on the tip of garlic or pale brown oval-shaped lesions on the surface of the leaves. When the disease is severe, the leaves die, the base rots, and the garlic plants fall. In the early stage of the disease, it can be controlled by spraying aluminum hydride, zinc, octylamine and water. The main pests in the garlic twitching period are root mites, thrips and aphids. The root lice will eat garlic bulbs, causing the bulbs to rot, harming the roots of garlic and reducing the absorption capacity of the roots. For the root can be used to control the roots of the national light poison arrows. When the thrips feed on the leaves of garlic, the leaves will become hard and deformed, resulting in insufficient supply of garlic nutrients, serious water loss, and the formation of garlic "horsetail" phenomenon, which seriously affects the quality and yield of garlic, and can be used for thrips. Spraying for prevention. 6, growth regulation The convulsion period is the symbiotic stage of garlic garlic and garlic cloves. Reasonable growth regulation can promote the extraction of garlic stalks on the one hand, and promote the transfer of the above-ground nutrients to the garlic stalks on the other hand to achieve the balance between vegetative growth and reproductive growth. In the garlic convulsion period, potassium dihydrogen phosphate + triacontanol cytokinin + calcium fertilizer can be used for foliar spraying to promote the organic nutrients synthesized by the leaves to the underground bulbs and promote the expansion of the garlic lobes. Note: When using the medicine, the dosage and the number of medications can be adjusted according to the growth of the garlic. It is generally recommended 2 times, with an interval of 7-10 days, and the water consumption per mu is 30kg. Garlic twitching is a process of vegetative growth and reproductive growth. The management of this period will directly affect the twitching of garlic and the expansion of garlic. Therefore, we must master the cultivation and management points of garlic during the pumping period. While strengthening the management of fertilizer and water, and doing well the prevention and control of pests and diseases, we must also use plant growth regulators scientifically and rationally, so that garlic can be produced with high quality and high yield. The above is the main point of management of garlic convulsions, I hope to help you, want to know more about agricultural technology, please pay attention to Hui Nong School!
