At the beginning of 2011, the Heilongjiang Provincial Meteorological Bureau organized a short-term climate prediction annual analysis meeting and annual analysis meeting, and conducted serious discussions on the pre-climate conditions, annual climate predictions and annual scenery. The comprehensive analysis concluded that the precipitation is normal this year and the temperature is slightly High, the season heat is enough, the overall meteorological conditions are better than normal, slightly worse than last year, is a good year (compared with the average of the past five years). The main disasters affecting agricultural production in Heilongjiang Province are: local drought in the western part of the spring, some elephants in the eastern part of the country, low temperature in the late spring, dryness in the summer, flooding in the summer, and early frost in the autumn.
First, the general trend of weather and climate
The general trend of climate in the province from March to October 2011 is expected: the temperature is slightly higher, the heat in the growing season is higher than normal, less than last year; the precipitation is normal.
Spring: Most of the spring precipitation is slightly more than last year. Most of the precipitation is in the late spring, including southern Daxinganling, Heihe, southern Yichun, Qiqihar, Daqing, Suihua, Harbin, Jiamusi, Shuangyashan, Mudanjiang and Jixi. More than 10%, other areas are 1~20% less than normal; spring temperature is close to normal in most parts of the province, cold air activity is frequent in early spring and late spring, the stage cooling process is obvious, the temperature is slightly lower; the final frost is normal.
Summer: The summer precipitation is normal, mainly due to local precipitation, and the summer precipitation is relatively concentrated. Among them, Qiqihar South, Daqing, Suihua, Jiamusi, Shuangyashan, Qitaihe and Jixi are about 10% more than normal, and other areas are 10% less than normal. Around; the summer temperature is slightly higher, the province's average is about 0.5 °C higher than normal.
Autumn: Autumn precipitation in most parts of the province is 1~20% less than normal; autumn temperature is slightly higher, which is lower than that in recent years. The average rate in the province is 0.2-0.5°C higher than normal. The first frost is normal earlier than average. 1 to 3 days earlier.
2. Forecast and analysis of agricultural meteorological disasters
1. Spring locality in the spring and soil drought in the summer. In the autumn of 2010, the average precipitation in Heilongjiang Province was 40mm, which was 50% less than the same period of the previous year, which was unfavorable for the increase of soil bottom. The last time (November 8th) before the freezing in 2010, the results showed that the soils in 34 counties and cities in the southwestern part of the plough layer (0~10cm) were poor, and the soil in 9 counties and cities was in a state of heavy drought. It has an important influence on the moisture in the spring soil after freezing, which greatly increases the possibility of drought in the spring ploughed soil. As of the end of January, Heilongjiang Province was covered by snow, and the snow depth of the main agricultural areas was above 10cm, which was conducive to winter soil conservation. According to the forecast, most of the spring precipitation was about 10% more than normal. More favorable. Based on the above analysis, it is expected that the soil drought in Heilongjiang Province will be mainly local in the spring sowing season, and the dry area is mainly located in the west of Heilongjiang Province. It is expected that some parts of Heilongjiang Province will have less water in the summer, so it is more likely that the field crops will encounter staged drought during the seedling stage.
2. After the spring, the temperature is low. It is predicted that the stage of cooling in the post-spring period of Heilongjiang Province is obvious, which has certain adverse effects on crop planting and emergence.
3. In the spring, the eastern part of the country is short-lived and the post-summer area is flooded.
4. Different levels of diseases or pests may occur locally.
5. There are sudden disasters such as hail, heavy rain and mudslides.
3. Analysis of the impact of meteorological conditions on agricultural production
1. Sowing period: According to the above analysis, the meteorological conditions during the spring sowing season have certain adverse effects on planting. The focus should be on the post-spring low temperature, which will affect the normal sowing and emergence of large fields in most areas, which may reduce the emergence rate. The second is to focus on the local soil drought in the west and the short-term guilt in some parts of the eastern region, which will be unfavorable for timely cropping of field crops and affect the quality of planting.
2. Daejeon growth period: This year's meteorological conditions are beneficial to the growth of field crops. The precipitation is normal throughout the summer, the temperature is slightly higher, and crops in most areas can grow vigorously. However, due to the uneven distribution of precipitation, precipitation is mainly concentrated in midsummer. Therefore, staged droughts, floods and local pests, hail and heavy rain will have certain adverse effects on the normal growth and development of local crops.
3. Grouting maturity: The temperature in autumn is slightly higher, and the precipitation in most parts of the province is 1~20% less than normal, which is very beneficial to crop grain filling and maturity. However, the first frost is 1 to 3 days earlier than normal, and the extremely late crops are not easy to mature safely.
Fourth, agricultural production advice
It is recommended that this year's agricultural production deployment arrangements and disaster prevention and mitigation focus on drought resistance, flood control and post-defense spring low temperatures.
1. It is necessary to fully consider the caloric status of the local crops to select crop varieties. Although the caloric conditions this year are slightly more than normal, it is not as good as last year. Therefore, it is recommended to prohibit the planting in the cross-region, and to mix the early, middle and late varieties properly. Try not to plant very late varieties.
2. Carefully prepare the spring ploughing work, select the seeds, repair the agricultural machinery in advance, and seize the favorable weather to carry out the farming activities such as land preparation, depression, and feces.
3. It is recommended to do a good job in spring breeding. Dry areas, especially in the western part of Heilongjiang Province, should focus on protecting, growing, and looting, cutting off peach water, making full use of rainwater resources, and striving to plant seedlings once; paying attention to drainage and ploughing in the eastern region, improving ground temperature and fighting for spring sowing At the same time, we should do a good job of preventing the low temperature in the spring after the prevention. If necessary, take measures such as covering and smoking to prevent low temperature and ensure the normal planting of crops.
4. All localities should pay close attention to the weather change situation, strengthen field management, scientific shovel, and rational fertilization to ensure the normal growth and development of crops.
5. In summer, Heilongjiang Province is prone to hail, wind, heavy rain and other disasters. If there are conditions, it is necessary to do a good job of eliminating cockroaches, flood control and anti-stage drought as early as possible, especially paying attention to all kinds of agricultural pests and diseases. jobs.
