According to agricultural technology extending stations of Beijing tongzhou, shunyi, well, such as eight counties of technical personnel, for the city's many times survey of 40 wheat positioning monitoring results show that the wheat turned green since the overall favorable weather conditions, combined with the previous administration, wheat group individual zhuang,'s is the best in the recent ten years.
According to agricultural technology extending stations of Beijing tongzhou, shunyi, well, such as eight counties of technical personnel, for the city's many times survey of 40 wheat positioning monitoring results show that the wheat turned green since the overall favorable weather conditions, combined with the previous administration, wheat group individual zhuang,'s is the best in the recent ten years.But the continuous high temperature, the influence of wheat growing process in advance, should change according to the practice of time management, all the year round to strengthen's and soil moisture monitoring, because of seedlings because of quantity management of later period.
Since the wheat root temperature obviously on the high side, sufficient sunlight, plant diseases and insect pests with wheat development process also happens in advance, therefore, field management and pest control to realize because of seedling management according to the index of wheat leaf age, at the same time pay close attention to soil moisture change, give full play to absorb the deep soil water potential of wheat, implementation for quantity of water-saving and high yield.
As soon as possible to complete filling water management.Green construction has been water management of the plot, jointing stage and water should be completed before, during, and after five Ye Lou pointed, mu shi urea 10-15 kg, 30-40 hectares of parties.Stage (not management, got up and made water management of land, and water will be postponed to six Ye Lou appropriate tip before jointing stage, urea 10-12.5 kg, mu shi mu irrigation 20-30.Larger crop, should choose the breeze below level (3) the weather watering, a water shoulds not be too big, lest produce lodging affect production.
Attaches great importance to the middle and later pest control, implement a multi-purpose.This year, according to the Beijing plant protection unit, plasma absorption insect medium, aphids lay particular stress on, want to do a good job of prevention and control of plant diseases and insect pests.Suction pulp insect to jointing stage and heading stage two control methods.Jointing stage can be combined with management and poison prevention and control of soil and water available per 250 ml of 40% phoxim oil, water 10 times dilution, spraying in 25 to 30 kilograms of fine sand, blending evenly along the wheat ridge after broadcast.Heading date available per acre 10% imidacloprid wettable powder 20 g + 80% dichlorvos ec 50 ml, or 4.5% efficient cypermethrin emulsifiable solution 40-50 ml + 80% dichlorvos ec leaf 50 ml plus 30-50 g, evenly spray water 30-40 kg.After wheat earing, when hundreds of aphid quantity reach more than 500 strains to timely prevention and control, prevention and control of pesticide varieties and dosage of reference to heading stage suction slurry method of worm worm.In case of wheat powdery mildew and rust, strain rate above 15%, can be combined with insect-resistant increase 20% powder rust ning emulsion 50 ml spray together.
To disease, insect at the same time, improve leaf photosynthesis and leaf function period, walter Ye Xiaomai can be dedicated, potassium dihydrogen phosphate and other foliar fertilizer mixed spraying with insecticides and fungicides, already can spray a multi-purpose, and can save labor, lower production cost.
The field of mixed.Wheat seed farm shall be carried out in the heading stage and ripening stage twice to miscellaneous, mainly is the remoal of plant height, spike and leaf color shape differences such as mixed strain or strain, inferior strains.To miscellaneous, whole pull out, should should not be cut, cut, in case of missing ear the following second tailing brace for miscellaneous pure protection during the harvest.
