From November 6 to 7, 2021, the northern region of China ushered in the first snowfall in 2021, although it has been detected in advance in various forecasts, warnings, and warnings, but really seeing the snowflakes fluttering, I still can't help but take a breath and say: "This is really cold!" ”。
The meteorological department said that the snowfall may be in the past 10 years, the earliest and largest scope of this weather, almost covering Shandong, Jiangsu, Hebei, Henan and other major garlic producing areas, the old saying often says "Ruixue Mega Year", from the perspective of agricultural production, snowfall on crop growth and soil moisture will bring certain benefits, but this year garlic due to autumn waterlogging planting time is generally delayed, garlic seedling nutrient accumulation is less, leaf growth is slow, the emergence of strong wind cooling weather will affect the growth of garlic seedlings? In order to help the majority of garlic friends to uncover the mystery, the international garlic trade network plant protection team has tracked the garlic seedlings in the snow-producing areas, Hebei, Jinan, Liaocheng area snowfall is larger, the ground is a white snow, affected by strong cooling weather, garlic seedlings in the field have been "er", the specific situation is as follows:
On November 7, there was sporadic snowfall in the Jinxiang production area, although the amount of rain and snow was not large, but the temperature dropped significantly, and its weather may have an impact on the planting of garlic seedlings that have just sprouted later, and the impact on the planting of garlic seedlings that have grown five-leaf and six-leaf relatively early is not large for the time being. This morning you can see the white frost in the ground, after the sun comes out, the temperature gradually rises, the garlic seedlings have recovered the "spirit qi", according to the weather forecast, the temperature in the Jinxiang production area in the next few days is above zero, and the observation of the growth of garlic seedlings needs to see the low temperature in the later stage.
Pizhou production area garlic planting time is relatively early, most of the garlic seedlings have grown to seven or eight leaves, yesterday the origin did not snow, just cooling rainfall, today the weather is sunny, the ground is green.
Qixian production area yesterday there was light snow, but the amount of snow is not large, the landing melted, this year's planting time is postponed backwards, planting garlic early and late, seedlings are uneven, some planting late plots have just budded, low temperature may have an impact on the growth of seedlings, but most of the plots of garlic seedlings are green and oily. Zhongmu production area yesterday morning there was an hour of snow, but the temperature drop is not large, at present, yesterday's rain and snow weather on the garlic seedlings in the ground has little impact, although there were eight to nine levels of wind yesterday, but because it is the first rain and snow, the film opened the situation is not much, garlic seedlings planted early there are four or five leaves and one heart, planting late are also three leaves and one heart.
Laiwu production area planting situation and last year is similar, the current planting of early garlic field has five to six leaves, planting late also four leaves, yesterday the rain fell a lot, the snow is basically melted, the impact is not big.
Daimyo production area yesterday encountered heavy snowfall weather, the temperature suffered a cliff-like decline, the minimum temperature in minus six or seven degrees, the weather after the snow clear, the temperature rose, the snow gradually melted, some of the late planting of garlic film was opened by the wind, are some of the early water planting late planting late plots, most of the fields are not affected.
Shanghe production area on November 7 there was heavy snow weather, due to the large amount of snow, some of the market inside the color steel greenhouse was crushed, the snow is about twenty centimeters, the current garlic seedlings have grown to five or six leaves, affected by the rainy weather in autumn and winter, garlic farmers overwintering water is basically omitted, the current garlic seedlings have ended, the windy weather has little impact on the garlic land, only a few large households planting time is late, may be affected.
Liaocheng production area the day before yesterday to yesterday there was sleet weather, the amount of snow is large and there is a situation of breaking branches, there is water in the garlic field, there are farmers draining and pumping in the morning, the garlic seedlings in the current field grow to six to seven leaves, the emergence rate is quite normal, basically do not need to water the winter water. It is understood that the mulch film of some large households with a slightly late planting time is lifted by the wind, which will affect the growth of garlic seedlings, and there are several local households that are prepared for garlic seeds, due to the emergence of this cooling and snowfall weather, resulting in the inability to plant.
Garlic is a relatively cold-tolerant crop and can tolerate short-term temperatures of -10 °C. If the low temperature time below -10 °C is long, or the extreme low temperature weather, garlic is very prone to freeze and kill seedlings. The unusually cold winter of 2015, coupled with the arrival of cold waves and rainy and snowy weather, caused garlic in Laiwu and Tai'an to be frozen to death in large areas, and garlic seedlings withered and burnt after the spring of 2016 made garlic farmers helpless.
Through the above discussion, it can be seen that the current round of cold wave raids is wide-ranging, almost covering the main and secondary production areas of garlic, the cooling range of each production area is different, and the temperature in the snow-after-snow production area has risen rapidly, which seems to be not as serious as in 2016, but it still has a certain impact on the later growth of garlic seedlings after some planting time delays. Between the current garlic or in the seedling growth stage, it is too early to determine the final production at this time, and there are many uncertain factors affecting the growth of garlic in the future.
From the perspective of spot trading, after entering November, the cold storage garlic transaction showed a fast situation, the agricultural busyness in the production area was basically over, the workers returned to their posts one after another, the orders in the direction of foreign South Asia, Southeast Asia and the Middle East were decentralized, the export processors were busy doing the cabinet at the end of the year, and the continuous slow rise in garlic prices also stimulated the increase in domestic demand, making the spot market transaction volume in the short term. Coupled with the upward trend of the electronic disk surface, the garlic field with late planting time, the growth trend of garlic seedlings is not as good as last year, and the sudden arrival of the cold wave has added a fire to the market, making the market bullish psychology in the stage rise, the price of cold storage garlic transactions has risen slightly, and the price of the general mixed grade in the Jinxiang library has risen from two pieces of six cents to about two pieces of seven, which has exceeded the highest price at the end of September and the beginning of October after the opening of the warehouse, and the price of fresh dried garlic outside the library is basically the same.
