玉米吃上“营养餐” “一喷多促”助增产_我的网站

一 |     8月16日，在邢台市南和区大郝村的玉米地里，一株株玉米挺拔整齐，种粮大户韩坤杰使用植保无人机对玉米进行“一喷多促”作业。“一架无人机一天能喷五六百亩地，我这2000亩地，两架无人机两三天就能喷完，省时省工省力。

二 |     CANBERRA, Australia -- A Chinese Australian journalist who was convicted on murky espionage charges and detained in China for three years has returned to Australia, Prime Minister Anthony Albanese said Wednesday.Cheng Lei, 48, worked for the international department of China's state broadcaster CCTV. She has reunited with her two children in Melbourne, Albanese said.Her return comes ahead of Albanese’s planned visit to Beijing this year on a date yet to be announced. He will become the first Australian prime minister to visit the Chinese capital in seven years.Albanese said Australia had traded nothing with China for Cheng's release.“Her release follows the completion of judicial processes in China,” he said.China’s Ministry of State Security said that Cheng had been approached by a foreign organization in May 2020 and provided them with state secrets she had obtained on the job in violation of a confidentiality clause signed with her employer. A police statement did not name the organization or say what the secrets were.A court in Beijing convicted her of illegally providing state secrets abroad and she was sentenced to two years and 11 months, the statement said. She was deported Wednesday after serving her sentence, presumably because she had already been detained for that long .“Her return brings an end to a very difficult few years for Ms. Cheng and her family," Albanese said. "The government has been seeking this for a long period of time and her return will be warmly welcomed not just by her family and friends but by all Australians.”The FreeChengLei account on X, formerly known as Twitter, posted a photo of Cheng with Australian Foreign Minister Penny Wong and Australia's ambassador to China, Graham Fletcher.The post included a quote, apparently from Cheng, that read: “Tight hugs, teary screams, holding my kids in the spring sunshine. Trees shimmy from the breeze. I can see the entirety of the sky now! Thank you Aussies.”Albanese’s government has been lobbying for the release of Cheng and another Chinese Australian held in China since 2019, Yang Hengjun.Bilateral relations have improved since Albanese's center-left Labor Party was elected after nine years of conservative rule. Beijing has lifted several official and unofficial trade barriers on Australian exports.Albanese's reference to China's judicial system suggested that Cheng had recently been sentenced after she was convicted in a closed-court trial last year on national security charges.Questioned by a reporter, Albanese said China was not acknowledging through Cheng's release that she posed no threat or had been wrongfully detained.“No, China would have not have said that that's the position. China would say that the judicial processes have been completed in China,” Albanese said.Chinese Foreign Ministry spokesperson Wang Wenbin said that the Chinese judicial system tried the case “in accordance with the law, fully safeguarding the rights enjoyed by the person concerned in accordance with the law.”Albanese said he spoke to Cheng in Melbourne, where her children have been living with her mother, and that they discussed a letter she had written to the Australian public in August to mark the third anniversary of her detention. The Chinese-born journalist spoke in her letter about her love for her adopted country.In the letter, she also described her living conditions in detention in China, saying she was allowed to stand in sunlight for just 10 hours a year.“She is a very strong and resilient person ... and when I spoke with her she was delighted to be back in Melbourne,” Albanese said.Albanese did not say whether Yang was also likely to be released.“We continue to advocate for Dr. Yang’s interests, rights and wellbeing with the Chinese authorities at all levels,” Albanese said.Yang, a 58-year-old writer and democracy blogger, told his family in August he fears he will die in a Beijing detention center after being diagnosed with a kidney cyst, prompting supporters to demand his release for medical treatment.Yang has been detained in China since January 2019, when he arrived in Guangzhou from New York with his wife and teenage stepdaughter.Yang received a closed-door trial on an espionage charge in Beijing in May 2021 and is still awaiting a verdict.Yang's friend, University of Technology Sydney academic Feng Chongyi, said on Wednesday a verdict had been postponed for three months 11 times and the next possible ruling was January.He said Cheng’s release was good news for Yang. “I do hope Yang is treated in the same way. Given Yang’s poor health, his release is actually more urgent,” Feng said.___Associated Press writer Ken Moritsugu in Beijing contributed to this report.___This story corrects the name of the Chinese security agency.。”韩坤杰说，以往人工喷施农药、叶面肥，存在喷洒不均匀、作业效率低等难题。现在植保无人机搭载精准雾化喷洒系统，将杀虫杀菌剂、叶面营养调节剂均匀喷施在玉米植株上，一次性完成防病虫、防早衰、促灌浆多重作业，让玉米吃上了一顿“营养餐”。眼下，南和区的玉米进入了灌浆期，这是产量形成的重要时期，也是病虫害集中发生期。“一喷多促”是玉米稳产增产的关键技术，通过一次喷施实现防病虫、促灌浆、增粒重、提单产的多重效果。为防治病虫害、促进秋粮生长，当地农技人员深入田间地头，为农户传授玉米病虫害防治方法，讲解水肥一体化灌溉技术要点。“我们开展‘一喷多促’技术推广，确保玉米稳产增产措施有效落地，全力以赴夺取秋粮丰收。”邢台市南和区农业农村局农技推广研究员温春爽说，作为粮食生产的关键技术，“一喷多促”将病虫统防、增重促灌、抗逆防衰、壮秆抗倒等多重功效集于一次喷施。同时配合施用磷酸二氢钾与氨基酸叶面肥，可延长叶片光合功能期，促进作物生长，提升单产水平。秋粮产量占我省全年粮食总产量的六成以上，病虫害防治是实现粮食稳产增产的关键。我省持续推进“虫口夺粮”行动，开展秋粮病虫防治，加密病虫监测网点，常态化开展田间拉网式普查，及时发布病虫预警信息。紧盯玉米螟、南方锈病等病虫害防控关键窗口期，各地大力发展统防统治、绿色防控，严防重大病虫害区域性暴发流行。

三 | 作为传统农业大县，武邑县今年整合12家规模化飞防组织，投入专业植保无人机120余架，并依据乡镇耕地规模与服务半径，搭建起“县级统筹+村级对接+组织作业”的一体化植保网络，全面推进“一喷多促”统防统治作业。田管跟得上，丰收有底气。我省以“提单产、保丰收”为目标，把夏播玉米作为主攻方向，组织专家制定夏玉米肥水管理、病虫害防控技术方案。

四 | 聚焦34个玉米、2个大豆整建制推进县和邯郸市整建制推进市、14个玉米单产提升工程县，打造一批千亩方、万亩片，树立高产典型。同时，省组织省级产业体系专家、农技人员进村入户，开展蹲点包片指导，重点落实科学肥水调控、病虫害防治等措施，持续挖掘单产潜力。用好中央资金和省级玉米“一喷多促”专项经费，落实“一县一策”，推动高产技术直达田间地头。（日报记者 郝东伟）。
