Attachment: 20 16 /article5.jsp technical advice on winter wheat spring management in Cangzhou city? infoId=47424 1

20 16 technical advice on winter wheat management in Cangzhou city at present, the wheat in our city is gradually turning green, and the production management has entered a critical period. Recently, the Agricultural Technology Extension Station of the Municipal Agriculture and Animal Husbandry Bureau, in conjunction with the Wheat Experimental Station of the National Industrial Technology System of the Municipal Academy of Agricultural Sciences and the agricultural technology extension stations in various counties and cities, organized experts to go to Suning, xian county, Botou, Huanghua, Cangxian, Zoje, Dongguang and wuqiao county (cities) in our city, and went deep into the fields to investigate the seedling situation, moisture content, diseases and weeds during the wheat turning green period in the city. After careful consultation, we put forward a proposal of 20 million pounds. 36800.6866868666 1

First, the characteristics of the current wheat seedling situation

In 20 15-20 16, the planting area of winter wheat in the whole city was 5,948,700 mu, an increase of 2 1.6 1.00 mu compared with last year's 5,732,600 mu, with an increase of 3.8%. Winter wheat turned green in early March this year. Generally speaking, it turns green normally and the wheat seedlings grow well. Although the temperature in late June of 5438+ 10 was 4.6℃ lower than normal, and even the extreme minimum temperature was-20.1℃ (23rd), due to more precipitation, the soil moisture in wheat field was good, and freezing injury and seedling death were rare, which realized the safe winter of wheat. The existing problems are: the main wheat field population is small and weak, and the threat of diseases, weeds and pests is more serious than that of perennials.

Comprehensive analysis shows that wheat has obvious advantages this year: First, the sowing quality is good. It is manifested in the popularization and application of multi-resistant water-saving and stable yield varieties, the increase of unified wheat seed supply area, the expansion of suppressed area after sowing, the obvious improvement of straw crushing quality and soil preparation quality, and the implementation of standardized sowing technology. The second is the balance of growth. Compared with last year, the proportion of first-class seedlings decreased, the proportion of second-class seedlings increased and the proportion of third-class seedlings increased slightly. According to the survey, the area of first-class seedlings accounted for 32.4%, which was 10 percentage point lower than the same period of last year. The area of second-class seedlings accounted for 49.6%, an increase of 9 percentage points; The area of three types of seedlings accounted for 65438 08%, an increase of 65438 0 percentage points. Third, the water is sufficient. From 65438+1 October1to165438+1October 30, the city's average precipitation was 70.5 mm, especially since June,165438+1October. At present, the soil moisture of wheat fields in our city is suitable, and sufficient moisture has created good conditions for the normal growth of wheat in spring. From February 26th to March 3rd, wheat fields in Botou City, Dongguang County, Zoje Academy of Agricultural Sciences and Cangxian County were tested. The soil water content of 0-5cm, 5- 18.2%, 25.6% and 10-20cm irrigated land in our city is 27.3%. The soil moisture content of 0-5cm wheat field in dryland is 18.4%, 5- 10cm soil moisture content is 19.3%, and 10-20cm soil moisture content is 24. 1%.

At present, wheat in our city is also facing some unfavorable factors. First, the individual is weak. During the period from sowing to overwintering of wheat, there are many low temperatures and few sunshine days, especially in the middle of June, 5438+065438+ 10, and the total sunshine hours are less than 15% of the same period of the year. During the period of1October 20-25 165438+, there was a large-scale snowfall and cooling process, and the lowest temperature reached-12. 1℃, and wheat entered the wintering period ahead of schedule, 7-10 days earlier than normal. The growth of wheat before winter is insufficient and the individual is weak. The age of main stems and leaves of main wheat fields in our city ranges from 4 leaves 1 heart to 5 leaves 1 heart, with 2.4 tillers per plant and about 3 secondary roots. Small leaves, less tillering, less tillering, low fresh weight of 100 seedlings, and all indicators of individual development are lower than the same period last year. Second, the population of late-sown wheat fields is insufficient. The total number of stems per mu in the main wheat field is 600,000-800,000, which is 8-65438+ 10,000 less than normal. The population is more suitable, and the management of wheat fields in early spring is more active. The population of late sowing wheat fields is insufficient, and the total number of stems per mu is mostly 500 thousand-550 thousand. Third, the early sowing of wheat fields in Wangchang is prone to freezing injury. 65438+ 10 in late June, the low temperature weather caused some wheat seedlings on the ground to turn yellow, causing serious freezing injury, and some wheat fields with poor soil preparation quality died. Fourth, the threat of diseases, pests and weeds has increased. Under the influence of continuous low temperature and insufficient sunshine and early wintering period, the area of weed control in autumn is obviously reduced, and the probability of weed occurrence in spring is increased. According to the investigation in Liu Zhuang, Dongguang County, weeds occur in spring, with 17 weeds per square meter and 286 weeds per square meter in serious plots. The climate is warmer this winter, and the probability of root rot and sheath blight increases.

Second, the spring management technical measures

According to the characteristics of current wheat seedling situation, the field management of spring wheat in our city should adjust measures to local conditions, strengthen classification guidance, highlight early characters, give priority to popularization, speed up the transformation and upgrading of seedling situation, build a reasonable population, prevent and control diseases, pests and weeds, do a good job of "one spraying and three prevention", and promote ear length and grain weight. Mainly do the following aspects.
