How to manage Chinese chives in autumn? How should Chinese chives be managed as autumn approaches? We ask netizens with experience growing Chinese chives to help explainChinese chives are a perennial root vegetable with strong adaptability, cold- and heat-tolerant, and are cultivated everywhere across the country. In many areas of the south they can be produced year-round; in the north, although the aboveground part dies back in winter, the underground part enters dormancy and sprouts and grows after the surface soil thaws in spring. Therefore Zhongdiwang has compiled the key management points for Chinese chives in autumn, listed in detail below for netizens' reference.
Point 1: Watering and fertilizing Chinese chives after the Beginning of Autumn:
After the Beginning of Autumn the weather turns cooler, light is abundant, and precipitation gradually decreases. Chinese chives photosynthesize vigorously, grow quickly, and direct nutrients to the roots for accumulation; this is the key period for strengthening seedlings and nourishing roots, so water and fertilizer management should be strengthened in autumn, which helps Chinese chives grow rapidly and accumulate nutrients. First open a furrow along the rows, and apply per mu 300-500 kg of decomposed soybean cake, 750 kg of high-quality farmyard manure, and 20 kg of ternary compound fertilizer. After fertilizing, cover with soil and water twice.
Point 2: Controlling growth of Chinese chives after Cold Dew:
After Cold Dew the weather gradually turns cold and Chinese chives grow slowly. At this time, watering and topdressing should be stopped so that the nutrients of the Chinese chives return early to the rhizomes and accumulate.
Point 3: Dormancy-inducing method for Chinese chives after Frost's Descent:
After Frost's Descent, set up a windbreak 1.3-1.5 m tall tilted toward the north along the front edge of the south side of the bed, to lower the bed temperature, force the Chinese chives into early dormancy, and reduce nutrient consumption; after covering at the Beginning of Winter, change the windbreak to tilt 15 degrees toward the south, making the south bed a warm bed.
Point 4: Management of Chinese chives after the Beginning of Winter:
Before covering, clear away all dead leaves and debris in the bed, cut off the withered Chinese chives, and apply 20 kg of urea per mu together with watering. After the water seeps down, build a small arched shed and cover it with film and straw curtains; uncover the straw curtains at 9 a.m. every day and cover them at 2 p.m., giving about 5 hours of sunlight, for darkening treatment. After 3-5 days, once the Chinese chives begin to sprout, uncover the film and spray with 25% carbendazim wettable powder or 40% triadimefon diluted in water to prevent gray mold of Chinese chives. After applying the pesticide, cover with soil in 2-3 rounds, with a total soil cover thickness of 5-10 cm, and earth up the roots after the Chinese chives emerge. In late November, when the Chinese chives reach 35 cm, cut the first harvest, and water and fertilize after harvesting.
