Tech-driven sugarcane farming boosts yields, cuts costs in Guangxi_我的网站

A |     (ECNS) -- At the "Sweet Light" modern sugarcane industrial park in Quli Town, Fusui County, in Chongzuo, south China's Guangxi Zhuang Autonomous Region, sugarcane varieties including Guitang 44, Yunzhe 081609, Guitang 76, Zhongtang 3, and Zhongfu 1 are thriving, with most stalks standing more than three meters tall.    The park rotates several varieties and plants them in separate zones to keep yields stable and the fields ecologically resilient.        Yang Xue, who has worked in the sugarcane industry for eight years and now runs an agritech company, has watched the shift from farming by experience to farming by data. Virus-free seedlings and the cultivation methods that go with them can extend ratoon cropping from three years to about five, he said, with germination rates reaching 95%. "In Chongzuo, per-hectare sugarcane yield used to be around 60 metric tonnes. With new varieties, improved cultivation methods, and planting models, yields have now risen to 72 metric tonnes," he said.    To manage the park's 333 hectares of contiguous fields, Yang's team has installed a smart irrigation system that combines water, fertilizer, and pesticide application. It can be run from a computer or a mobile app, with irrigation timing, flow, and volume set precisely. One worker can now cover more than 67 hectares.    The system has since been upgraded to a dual-pipe design, Yang said, allowing water, fertilizer, and pesticides to be applied together and accurately. Annual electricity costs have fallen from 1,200 yuan (about $168) per hectare to 750 yuan (about $105). Four workers can now fertilize 40 hectares in a day, work that previously took 30 workers to cover less than seven hectares.        Mechanized harvesting has cut costs as well. Cutting and loading by hand costs more than 16,500 yuan per hectare, based on a yield of 105 metric tons per hectare and a rate of 160 yuan per metric ton. With machine harvesting, farmers receive a state subsidy of about 3,000 yuan per hectare and pay only 750 to 1,200 yuan for the service. The park also returns chopped stalks to the fields, saving another 450 to 600 yuan per hectare in fertilizer.    The Chinese Academy of Tropical Agricultural Sciences (CATAS) has been working with the Guangxi Academy of Agricultural Sciences and other institutions on variety improvement, seedling propagation, pest control, green cultivation, and mechanical harvesting.    Wu Qibin, a researcher at the Sugarcane Research Center of CATAS's Institute of Tropical Bioscience and Biotechnology, said Guangxi is China's core sugarcane-producing region, with more than 800,000 hectares under cultivation and over 60% of national sugar output. The industry is now pursuing two main goals, he said: breeding high-quality varieties suited to machine harvesting, and developing specialized machinery matched to those varieties.    (By Tang Yuxian)                    。

B |     据都市快报消息， 1月9日下午3点50分左右，日本兵库县的两名中国女游客在铁路道口等红绿灯时遭列车撞击身亡。一男子发现两名女子重伤倒地后报警，其中一女子当场身亡，另一女子送医后身亡。警方在两人的随身物品中发现中国护照。据上海电视台新闻综合频道《新闻坊》消息，通过入境时的指纹对比，两位中国姑娘的身份已经被确认，正在联系家属。调查发现，事故发生前，被撞的两名女性站在公路和铁路平交道口已放下的禁止通行护栏处。日本警方推测，两人或误以为铁轨内是“信号灯等待区”。

C | 列车司机说：“我看不到她们，因为她们在铁路道口的电线杆后面，被电线杆挡住了。”警方将继续调查当时发生的详细情况。《新闻坊》介绍说，发生事故的神户市垂水区路段，情况复杂是当地民众公认的危险地带。要穿过2条铁道线，在铁道与公路之间的“隔离区”等红绿灯过斑马线才能抵达对面，事故就发生在这个隔离区。这个隔离区不仅特别窄还是个斜坡，也就成年人的两肩那么宽，推自行车的话，前轮都要进入斑马线。因为过于危险，有警告牌写着禁止小学生穿越这条路，可以走西舞子车站的地下通道，有些绕道，需要多走10到15分钟。

D | 当地居民都知道在这个铁路线外侧，又窄又陡的隔离区等红绿灯很危险，感觉早晚要出事，但没想到会是在铁路线内侧发生这么严重的人身事故。根据电车司机的证词，发生碰撞时，两人是站在铁路线区域内，面朝公路方向，应该是等红绿灯要过马路。

E | 对于可能造成事故的理由，有以下猜测： 第一，电车经过时的噪音并没有想象中的那么大，公路上货车频繁经过，车速快，噪音也大，如果戴着耳机的话，很难在更早些的时候发现电车正在靠近。第二，穿越过铁道后，要摁下过马路的专用摁键，红绿灯才能切换。如果安全杆已经放下来，也可以越过这个安全杆，摁下这个摁键。但外国游客的话，可能很难留意到这个设置。第三，也可能是两个人一边说着话一边走，都未注意到自己还站在铁路线区域内。网友对此议论纷纷。有网友提出了疑问，“为什么会站护栏内等红绿灯”“火车来有声音，都不看吗？” 也有不少网友表示，事发路口及类似道口存在危险性且有误导性，“说老实话这个踏切我要是遇到了，也会不自觉地站栏杆里面。” 也有网友建议，最好画明禁止区域，做好安全指示。（综合自都市快报、新闻坊等） 本文系观察者网独家稿件，未经授权，不得转载。
