How to scientifically carry out water and fertilizer management during the bolting period of garlic?

  Garlic was introduced into China from the Western Regions during the Qin and Han Dynasties. It was cultivated by artificial cultivation and has anti-cancer effects. It is popular among the public. Wet and fear of drought, the soil requirements are not strict, but rich in organic matter, loose and breathable, water retention and drainage function is more suitable. So how is the scientific management of water and fertilizer in the garlic extraction period?

1. Sprinkling water before the bolting of garlic is correct. Because this time is the critical period for garlic to require water, it has a great impact on the output value. When the garlic is sold, it can be poured. At this time, the garlic harvest is less than one month, which has an impact on the output value of garlic. Depending on the moisture of the soil, it may be necessary to pour more than one water. Now that the temperature is gradually rising, it is very important to improve the production value and quality of garlic in the middle and late stages of garlic growth.

    2, bolting garlic field, should be combined with fertilization, 5 kg of urea, 15 kg of compound fertilizer, 10 kg of potassium sulfate. At this moment, the garlic field should not be dry, and there should be enough water to supply the growth demand of garlic to prevent the phenomenon of “tube leaf” due to drought at this moment. Field management should be strengthened, drainage should be carried out in time after the rain, the humidity in the field should be lowered, the environment for plant growth should be improved, and the disease resistance can be improved.

    3, together with prevention and control of garlic leaf blight, in the early stage of the disease (to timely adopt effective control measures to prevent disease expansion and extension), 50% of prochloraz oil 30 ml per acre, or 10% difenoconazole 40 g of water-dispersible granules, or 40 ml of 80% allicin emulsifiable concentrate, or 77% can kill 60 g of wettable powder, sprayed with 60 kg of water, once every 5-7 days, and 2-3 times in succession. Replace the application, the effect is better. Spraying with plant amino acid foliar fertilizer or potassium dihydrogen phosphate can help the garlic to recover.

    4. Stop the irrigation for three days before harvesting the garlic moss to prevent it from being easily broken when harvesting the garlic. Garlic moss is about 15 centimeters higher than the final leaf, and the garlic moss is harvested at the beginning. After collecting garlic moss 1-2 times, it should also apply 3-5 kg of urea in combination with irrigation to accelerate the elongation of the stem and accelerate the increase of scale buds. After the harvest of garlic and garlic, the bulb is in a period of expansion and vigorousness. In addition, the temperature rises and the soil transpiration is large. In this period, the water should be filled with water. Promote the fatness of the garlic, 7-10 days before the harvest of the garlic, stop the irrigation, and adhere to the outstanding garlic traits.
