北京市针对小麦生产中存在的播种质量差造成田间缺苗断垄、导致亩穗数少、产量低,冬春季寒旱影响造成土壤裂缝、干土层较厚不利小麦安全越冬,农户对结合化学除草、吸浆虫和蚜虫防治喷施叶面肥等一喷多用技术掌握不全面,以及对小麦苗情、墒情把握不准、春季肥水运筹不科学、影响小麦分蘖成穗率、穗粒数和千粒重等问题,2013年北京将重点推广以下四项核心技术,为北京市小麦高产创建保驾护航。
In Beijing, poor seeding quality in wheat production resulted in lack of seedling and broken ridge in the field, resulting in fewer ears per acre and low yield, soil cracks caused by the cold and dry conditions in winter and spring, Weeding, inhalation of aphids and foliar spray prevention and control of sprayed with a multi-purpose spray technology is not comprehensive, as well as wheat seedlings, soil moisture is not allowed to grasp, spring fertilizer operation unscientific, affecting the tillering rate of wheat, spikelets and thousand kernel weight Issue, in 2013 Beijing will focus on promoting the following four core technologies to create high-yield wheat in Beijing.
