今年我国蔗区秋季雨量大,气温高,台风发生早,甘蔗生产管理难度加大,为加强生产指导,全国农业技术推广服务中心会同国家糖料产业技术体系,研究制定了《2017年甘蔗秋季生产技术指导意见》。1水肥管理秋季是甘蔗产量形成的关键时期。如遇旱季,每10天左右要深层灌溉一次,保持土壤表层以下50厘米范围内的含水量达最大持水量的80%以上。此时期植株养分需求量也大,要根据田间
This year, China’s sugarcane harvest in autumn rainfall, high temperatures, early typhoons, sugar production and management more difficult to strengthen production guidance, the National Agricultural Technology Extension Service Center with the national sugar industry technology system, developed a “sugar cane autumn production in 2017 Technical guidance. ” 1 water and fertilizer management autumn sugar cane production is the key period. In the case of the dry season, deep irrigation should be carried out every 10 days and the water content in the range of 50 cm below the soil surface should be maintained above 80% of the maximum water holding capacity. Plant nutrient demand during this period is also large, according to the field
