Right now, wheat is gradually entering the wintering period. How to strengthen field management and lay a solid foundation for a bumper harvest next year has become the most concerned thing for growers. According to the national climate trend forecast and consultation data, it is expected that the cold air activities affecting my country will be frequent and strong this winter (December to February next year), mainly affecting my country through the northwest route. Especially in the middle of winter (January next year), there may be a wide range of strong low temperature rain and snow. Once an extreme weather event occurs, it is very likely that a large area of ​​wheat will die, which will pose a serious threat to the summer grain harvest next year. In this regard, the majority of farmers and friends should strengthen the management of wheat overwintering and improve the ability of wheat fields to resist freezing. Specifically, the following three technical measures should be adopted: The first is to cultivate strong seedlings to improve frost resistance. Weak seedlings that are sown late should focus on foliar spraying and cultivating to increase temperature to promote early emergence of wheat seedlings. For the flourishing long wheat that is planted early or with a large amount, it can be cultivated and rolled to promote the next rooting and eruption, inhibit the growth of small tillers or excessive tillers, and chemical control such as "Zhuangfengan" can also be used. For the strong seedlings sown in the right time, chemical weeding or inter-tillage weeding should be carried out in time to prevent weeds from competing with wheat seedlings for fertilizer, water and sunlight. The second is to pour winter water to stabilize the temperature of the wheat field. Seedlings with hanging roots and drought (the relative moisture content of the soil in the root layer before winter is less than 75%) are the most problematic seedlings. For plots that are extensively cultivated, more stubble, and straw returned to the field, winter watering should be done earlier. In the strong seedling wheat field, the average temperature of the day drops to about 5℃, and when the night freezes and the day disappears, the winter water is ******. It is recommended that the well irrigation area adopt the method of pipeline water delivery + small border irrigation, with 40-50 cubic meters of water per mu. The canal irrigation area adopts small or narrow border irrigation, with 50-60 cubic meters of water per mu. If there are sprinkler irrigation conditions, 15-30 cubic meters per mu should be irrigated according to the moisture condition of the wheat root layer. The weaker growing wheat field combined with winter irrigation can apply 5-10 kg of urea per mu. The third is cultivating and harrowing to ensure the safe overwintering of wheat. Before the wheat overwintering and freezing, all kinds of wheat fields, especially those with severe cracks after watering, must be promptly and generally used for field hoeing or rolling and raking. Straws can also be used to cover the wheat fields, and spread livestock manure or farm soil. Measures such as fertilizer. Disclaimer: Some articles on this website are transferred from the Internet.

Due to the irregular characteristics of the pelvic structure, the choice of internal fixation is diverse.
For patients separated symphysis pubis, a 2 or 4 holes, 4.5 or 3.5mm diameter dynamic compression plate or reconstruction plate can be used and fixed with full-thread cancellous bone screws.Another method of fixation is lag screw fixation. In patients with new sacroiliac joint dislocation with a forward approach,firm fixation can be achieved by using 2holes 3.5mm dynamic compression plates through the front of the sacroiliac joint. The posterior approach can also be used to insert 6.5mm lag screws into the sacral wings or hollow cancellous bone screws with interosseous compression for firm internal fixation. If available, the fracture may be fixed with 3.5mm or 4.5mm pelvic reconstruction plates and appropriate full-thread cancellous bone screws.
