Strengthening the field management of 8.42 million mu wheat in Nanyang City, Henan Province

Introduction: In this year's wheat sowing work, Nanyang City, Henan Province conscientiously implemented the spirit of the No.1 document of the Central Committee and No.4 document of the provincial Party committee, took wheat sowing as a stage assault center of agricultural and rural work, seized the favorable opportunity of the current sunny weather and suitable soil moisture, accelerated the progress of wheat sowing, and ensured the end of wheat sowing in the proper sowing period of the city Wheat sowing is the best one in recent years Year According to the investigation and statistics of the municipal agricultural technology station, the wheat planting area of the whole city is 8.42 million mu, about 30% of the wheat field is one leaf to one leaf, with 243000 basic seedlings; about 65% of the wheat field is two to three leaves, with 176000 basic seedlings per mu; about 5% of the wheat field is three leaves to five leaves, with an average tiller (including main stem) of 17, with 164000 basic seedlings and 280000 population Although the wheat seedling situation is generally better this year, there are still some problems First, a small number of wheat fields are sown earlier, with a large amount of sowing In addition, the soil moisture is better, the temperature is higher, and there is a trend of vigorous growth, especially for the weak spring varieties with early sowing Second, some wheat fields with late stubble and extensive land preparation have the phenomenon of lack of seedlings and ridge cutting Third, a small number of Hilly Areas There are drought phenomena in local wheat fields, and some livestock and poultry are biting November is the key period of wheat management before winter All regions should take measures according to local conditions and seedling conditions, strengthen field management practically, control the vigorous and promote the strong on the basis of realizing seedling uniformity, seedling integrity and seedling uniformity, and realize the safe overwintering of strong seedlings 1 Check the seedlings and replant All localities should do a good job in the investigation of wheat sowing basis and seedling situation, organize the masses to replant the plots without seedlings and ridges in time, and evenly transplant the tillered wheat fields without seedlings to make up for the thinness 2 Strengthen the management of wheat field with the emphasis on controlling the prosperity For early sowing and flourishing wheat field, deep hoe and suppression should be taken as the main measures; for large sowing and flourishing wheat field, suppression should be taken as the main measures; for early sowing and large sowing wheat field, measures such as manual seedling removal, horizontal harrow and seedling thinning, deep hoe and root cutting should be taken in time, and then suppression For the weak seedling field, early management and early promotion should be carried out, and the soil in the middle ploughing should be loosened to increase the temperature and soil moisture, so as to promote the root and tiller; for the wheat field with insufficient basal fertilizer, it is necessary to take advantage of the soil moisture to supplement the fertilizer; for the strong seedling planted in time, it is mainly in the middle ploughing and suppression, so as to promote the root and tiller of wheat 3 Pest control In the wheat field without soil treatment or chemical dressing, phoxim or trichlorfon were used to control grubs, golden needles and other underground pests At the same time, it is necessary to strengthen the monitoring and control of sheath blight, wheat aphid, wheat spider and other diseases and insect pests, control the harm, and reduce the base number of diseases and insect overwintering 4 Chemical weeding The effect of weed control before winter is the best Seizing the opportunity, scientifically select baicaodi, dimethyltetrachloride, giant star and other pesticides for chemical weeding The application time should be at least 5 ℃ after two leaves of wheat 5 Timely drought resistance and wheat irrigation According to the forecast of the meteorological department, the precipitation of the whole city is less in November For the wheat field with drought, the masses should be organized in time to carry out drought resistance and wheat irrigation 6 Prevention of wheat freezing injury In view of the large proportion of weak spring wheat varieties and early sowing date this year, it is necessary to pay close attention to the weather changes and make plans in advance to prevent the wheat field from freezing injury 7 It is strictly prohibited for livestock and poultry to eat green.
