To grasp the current wheat situation in the county, to provide the scientific basis for field management in winter, on November 23, Xiannong Wei also organized the county wheat yield Seedling Situation field research carried out a full investigation.
The county this year, a total of 135 acres of wheat planted, of which the implementation of high-yield research field of 25 acres of wheat. Survey of 60 points by the county wheat yield research field there are three characteristics, namely, concentration of wheat sowing, planting fast, the quality of autumn than in previous years. Second, the research field of wheat yield four key high technology in place. High-yield varieties of wheat field research throughout the county to achieve 100% coverage of more than 9.2 kilograms per mu seeding rate, soil testing and fertilization area of 80%, integrated pest management area of more than 95%. Third, adequate soil moisture, soil preparation of high quality, neat emergence, Seedling Situation better. Seedling Situation survey: the average per mu of planting density 189 200 (up to 230,000, the lowest 160 000), tiller 131,500 (up to 200,000, the lowest 20 000), total tiller 319,200 (up to 390,000, the lowest 240 000), 0.7 tillers per plant (maximum 1.25, minimum 0.09), secondary root 3 (more than 5 persons), 5 leaves a heart or 4 leaves to the stem 1-2cm. Wheat growth robust, dark green leaves hypertrophy, about 8mm in width, consistent with emergence, growth and tidy. Winter wheat county first and second vaccine will reach about 90% the proportion was significantly better with.
Although the overall quality of the county in Autumn is better, but there are still some problems. The first part of the semi-winter wheat sowing and late; rotary area, part of the rotary Tiankuai less than 15 cm deep tillage, topsoil lighter, is not conducive to root development, accounting for about 12% of the total area; Second, some places sowing rate is still too large, and a handful of broadcast Tiankuai will inevitably cause the group is too large, population density ones, lurking pests and diseases, lodging and other risks. Third, in November this year, daily average temperature is about 3 higher than in previous years, there are naturally vigorous growth trend. Overall, the county this year, in autumn soil preparation of high quality, planting fast, more appropriate sowing date, sowing quality is good for one year in recent years. Wheat growing county is better now for next year's summer grain harvest basis.
For wheat production this year, the main problems, Xian Nongwei winter field management measures proposed. First, chemical weeding wheat vigorously. As the autumn rain, weed seed source volume, coupled with the recent soil humidity, resulting in more weed base, we must seize the favorable opportunity before winter to vigorously promote the wheat fields of chemical weed control technology, control wheat weeds. Second, timely cultivators. Seedling Situation under wheat, soil moisture, timely carry out cultivation, weed and warming soil moisture, control Wang promote strong, winter 1-2 times before the ordinary cultivator. Third, to make up Miaofei. Some late sowing Tiankuai, Seedling Situation in development slightly later, in the field to promote the main pipe to promote seedling winter. Poor soil fertility, fertilization field with enough early topdressing Miaofei, the Prince of applied fertilizer, promote weak to strong. Fourth, prevention of pests and diseases. Adhere to the main case, combining prevention with control, good survey of wheat diseases and pests early, once you achieve control targets, must timely spraying, particularly of wheat sheath blight, aphids, spider mites and other multiple diseases and pests, early prevention.
