One of the 1 selected varieties used in the selection of high-quality multi-spike wheat varieties such as Jimai 22, Jinan 17 and Jinmai 20 as the main planting varieties; Electric UTV,Best Electric UTV,Electric 4X4 UTV,Electric Side By Side TAIZHOUÂ NEBULAÂ POWERÂ CO.,LTD , https://www.xingyunutv.com
2Appropriate close planting, suitable late seeding of Jinan No. 17 and No. 22 Jinmai, etc. The control of multi-spike varieties in the basic seedlings is in the range of 100,000 to 120,000; the sowing time is appropriate from October 3 to October 10; 3cm.
3 Implement soil testing and formula fertilization techniques, and focus on the specific fertilization scheme for balanced fertilization: base fertilizer Mushi pure nitrogen 6kg, P2O5 7kg, and K2O 7.5kg; nitrogen topdressing time is postponed from the traditional returning stage to the jointing stage, and the recovery of pure nitrogen is 8-10kg.
4 do a good job of water-saving irrigation, pouring a good key water in the whole growing period of wheat pouring "four water", that is, with the kind of water, winter water, jointing water, Yanghua grouting water. The wintering water should be postponed until the end of November to the beginning of December. The jointing water can be combined with spring dressing in the late March to early April. In the middle and early May, the filling water for spring flowers should be poured. If the wheat has more precipitation before winter and there is sufficient bottom, wintering water can be saved. During the winter and early spring, it is necessary to do a good job at the proper time.
5 Comprehensive promotion of comprehensive prevention and control techniques Wheat pests and diseases shall be comprehensively controlled in four stages according to the growth period and the occurrence of pests and diseases, ie sowing - wintering period, returning green - jointing stage, heading - flowering stage and grain filling stage.
I. Sowing - During the overwintering period of winter wheat sowing, it mainly controls underground pests and concurrently treats wheat bush dwarf disease. The methods used are mainly seed dressing or coating. Herbicides are applied to control field weeds in early November.
II Returning to greening - The greening and jointing stage of jointing stage mainly controls the wheat sheath blight and wheat leaf bee; at the same time, it should do a good job of chemical resistance control and spray “Zhuangfenganâ€; spray the special wheat to control the late wheat powdery mildew, rust, Scab.
III Heading - During the flowering period from heading to flowering stage, it mainly controls the spider mites, powdery mildew and rust.
IV filling period in the end of April and May the first half of the year with imidacloprid, wolfberry killing and planting Ning mixed spraying, is strictly prohibited with omethoate, 1605 and other highly toxic, high-residual pesticides control wheat stubble.
two
1, "three delays"
(1) Delaying the sowing of wheat: The sowing time of wheat in the county was postponed from around September 27 to around October 5.
(2) Delaying the watering time of wintering water: The utilization time of wintering water in the county was postponed from the middle of November to the end of November to the beginning of December.
(3) To postpone the application time of the first fertilizer in spring: The application time of the first fertilizer for spring wheat in the county was postponed from mid-March until the end of March to the beginning of April.
2, "Four reductions"
(1) Reducing the seeding amount: 2001-2008, the wheat seeding experiment was implemented in succession, and the optimum seeding amount of each type of wheat suitable for the actual production in Fujian and Taiwan was determined through experiments. The county's wheat sowing rate has been reduced from the original 10 kg per mu to about 7.5 kg.
(2) Reducing the amount of nitrogen fertilizer: From 2002 to 2004, the best proportion of wheat was tested continuously. Through the experiment, the optimum amount and proportion of wheat in the county were determined. The amount of nitrogen fertilizer per acre was reduced from 22 kg to 16 kg. about.
(3) Reducing the number of watering: The water-saving irrigation technology centered on pouring key water was formed through experiments. The county’s entire wheat growth period was reduced from the original 5-6 water (with seed water, wintering water, returning green water, jointing water, grouting water, and falling yellow water) to 4 water (with seed water, wintering water, jointing water, grouting) Water), 1-2 less water than conventional.
(4) Reducing the amount of highly toxic pesticides: Promote the use of high-efficiency and low-toxicity insecticides such as cockroach-killing and anti-fog, and do a good job of preventing and controlling wheat cockroaches. The use of highly toxic pesticides such as 1605 is strictly prohibited. Huantai County Agricultural Technology Promotion Center
