Spring cultivation in spring in some parts of the country faces new challenges

Since March 1, most of the cold and rainy weather in the south of the Yangtze River and southern China, the precipitation days in the central and western parts of the south of the Yangtze River and the western part of South China have reached 15 to 22 days; the daily average temperature in the early rice area of ​​the south of the Yangtze River is less than 12 °C, the number of days is 15 to 20 days. The northern part of South China is 11 to 16 days. The continuous low temperature and rainy weather caused the early rice soaking in the north and south of the Yangtze River to be slightly later than last year; the early rice in the southern part of South China grew slowly.

The low temperature and rainy weather in Guangxi is more obvious. Since March 1, the temperature in Guangxi has been significantly lower. In most areas, the rainfall and rainy days are more, and the light is seriously less. Low temperature and rainy rain is unfavorable for seedling and growth of early rice sowing and spring dryland crops. The seedlings grow slowly and are generally yellow weak. In addition, Guangxi is the main sugarcane production area, and unfavorable meteorological conditions may lead to a decline in sugar cane content in this season. Low temperature and low temperature still bring harm to various warm crops. In this regard, Guangxi Meteorological Bureau recommended: strengthen early rice seedlings care to prevent rotten sputum; areas in southern Guangxi that have not yet completed the sowing task should speed up the progress of breeding; Guizhong and Guibei should vigorously promote cold-breeding and other cold-breeding techniques; low-lying areas, soils Wet plots should be opened in a timely manner. In the past few days, the business service personnel of the Guangxi Meteorological Bureau have gone to four cities to conduct research, go deep into the fields and farmers, and keep abreast of the agricultural production situation, and compiled the "Relationship between the early rice planting and transplanting period and the requirements for meteorological conditions".

“The weather has been cold for a long time since the beginning of this year, which has a certain impact on the growth of wheat canola and the planting of early grain.” Zhou Xunxiang, a villager living in Daomawo Village, Xindian Town, Qingzhen City, Guizhou Province, said this when talking about the current low temperature weather. According to Hu Jiamin, an agro-meteorologist at the Guizhou Institute of Mountain Environment and Environment, since February 28, due to the continuous invasion of cold air in the south, most areas of Guizhou have experienced low-temperature weather. In addition to the southern margin, the average daily temperature in other regions has remained at 10 Below °C. Affected by this, the growth period of wheat and rapeseed is generally postponed; the fruit trees such as pear trees in the first flowering leaves are unfavorable; the vegetables in the southern region are slow, which makes the vegetables in the off-season from April to May even lighter. In addition, low temperature chilling will seriously affect the time to market for spring tea. Duyun City Government Tea Industry Office Mr. Meng said that due to the continuous low temperature effect, although the spring tea has been listed, but compared with previous years, the output is not large, and only from lower altitudes. Chen Zhishu, a walnut dam village in Meitan County, told the reporter that the tea garden in the village was affected by the persistent low temperature this year, which caused the germination to be abnormal. Not only was the tea picking time delayed, but it could also cause about 20% loss. In response to the continuous low temperature weather, meteorological departments at all levels in Guizhou made predictions and warnings in advance, strengthened monitoring and intelligence services, and made scientific suggestions for party committees, governments and relevant departments at all levels.

Affected by cold air, from March 22, the cold weather in the north-central part of Guangdong has a great impact on crops, especially on melons and other economic crops. Song Wei, assistant researcher of the Vegetable Research Institute of the Guangdong Academy of Agricultural Sciences, said that from the "back to the South" suddenly changed to the "cold spring" weather, melon, loofah, bitter gourd, beans and other factors are most susceptible to pathogens, fungi and other will make the leaves of melons and vegetables long White spot, even when the vine leaves withered, died, causing huge losses to the vegetable farmers. Low temperature and rainy weather will also slow down the growth of melons, leading to a reduction in production. Over time, the supply of vegetables on the market will be “broken”. Chen Chunfeng, a researcher at the Guangzhou Fruit Tree Research Institute, said that it is the flowering of the early-maturing lychee “March Red” in Guangzhou. The cold and cold weather will inhibit the flowering of the fruit trees and even stop the growth of the flowers, and the fruit will be delayed and the maturity will be delayed. The Guangdong Meteorological Bureau has submitted a major meteorological information bulletin about the cold spring to the provincial party committee and the provincial government on the 19th. The Shaoguan Meteorological Bureau also issued a weather report to the local agricultural departments and townships. According to the weather forecast, Wujiang District of Shaoguan City dispatched 20 agricultural technicians to assist the farmers to do a good job of covering the film, dredging and drainage, and adding the “cold spring cold” defense work.

Since mid-March, the cold weather in Hunan has continued, and the rain has been lingering. “On the 17th, rainfall in Hunan continued for a long time, and the overall rainfall was not large. It was mainly rainy, but the rain and rain had adverse effects on agricultural production,” said Yao Rong, chief forecaster of the Hunan Provincial Meteorological Observatory. As of the 24th, Hunan has been below 10 °C for 5 consecutive days, and the provincial capital Changsha is only about 8 °C in recent days. This continuous rainy weather will have an impact on spring sowing production and rapeseed production. In Hongqi Village, Yong'an Town, Changsha City, the rapeseed during the flowering period is washed away by rain in the past few days, and pollination and later fruiting will be affected. Low temperature and rainy rain is also unfavorable for early rice planting. In Jintang Village, Huanghua Town, Changsha, the reporter saw that half of the villagers had spring sowing. Meteorologists reminded that it is best for farmers' friends to soak seeds and germination in the cold air. When the cold air is over, they will be ploughed and planted. They can seize the "cold tail warm head" and have a good time to carry out early rice planting and breeding work. In the face of the critical season of spring sowing, the Hunan Provincial Meteorological Bureau has twice sounded the cold wave blue warning and released two issues of “Key Farming Season Meteorological Service”. It is recommended to pay attention to the spring sowing weather, timely soaking seeds, and strengthen the management of nursery, in late March. It is advisable to plant the mud in the later stage.

Since March 21, Jiangxi has experienced significant cooling, precipitation, and windy weather due to the cold air in the north. As of the 23rd, the western region of central Yunnan has been in existence for 2 days. The minimum temperature is below 10 °C, and the sunshine is less than 1 Hourly low temperature and rainy weather. According to the survey of the meteorological department of the province, due to the influence of low temperature and rainy weather, the progress of spring sowing in the province is slightly later than that of the same period of last year. Among them, the early rice soaking is 790,000 kilograms less, and the transplanted early rice transplantable area is 240,000 mu. In order to reduce the adverse impact of the disaster weather on the spring sowing, the Jiangxi Meteorological Observatory closely followed the weather development trend and provided decision-making services to the provincial party committee, the provincial government and relevant departments on the 18th and 20th, reminding that “some areas in the early part of the next period will be light. The cold weather is not good for spring sowing. On the 20th, a special report on the spring broadcast spring weather service was also issued, which was provided to the Provincial Grain and Oil Bureau, the Economic Affairs Bureau, and the Agricultural Technology Extension Station by fax or e-mail. On the 22nd, the meteorological and agricultural departments jointly carried out propaganda on the prevention of low-temperature and rainy disasters. It is recommended that the soaked early rice be thinned and dried, and the early rice planted should be strengthened to strengthen the management of the field, and the suitable sowing date of the early rice was proposed.
