Fast radio bursts(FRBs) are highly dispersed millisecond-duration radio bursts,[1.2.of which the physical origin is still not fully understood. FRB 2.2.11.4A is one of the most actively repeating FRBs. In this paper, we present the collection of 1.63 burst dynamic spectra of FRB 2.2.11.4A measured with the Five-hundred-meter Aperture Spherical radio Telescope(FAST). The current collection, taken from the observation during the FRB active phase from April to June 2.2.0} is the largest burst sample detected for any FRB so far. The standard PSRFITs format is adopted, including dynamic spectra of the burst, and the time information of the dynamic spectra, in addition, mask files help readers to identify the pulse positions are also provided. The dataset is available in Science Data Bank, with the link https://***/1..57760/sciencedb.j001.3.00076.

以全国甘蔗生产信息监测网中我国糖料蔗主产区种植品种相关监测数据为研究对象,分析了2.14~2.19年我国糖料蔗种植品种结构的状况与变化趋势。6年内,我国糖料蔗主产区主栽品种包括{2.个品系的78个品种,其中进入各监测县面积前4位的品种47个,累计种植面积超过{2.万hm2.品种只有7个,其中ROC2.是唯一面积达到百万公顷的品种。在不将ROC2.纳入良种的情况下,当前我国的糖料蔗良种率依然偏低。在植品种多而杂、品种结构不尽合理、种植规划水平低是当前我国糖料蔗种植品种结构存在的普遍不足。但在一系列改革措施下,新良种得到快速推广,良种率逐年提高,品种结构不断改善成为趋势。就目前我国糖料蔗品种结构现状,本文提出了建立糖料蔗产业参与者合理利益分配机制、加大良种种植政策支持、加强育种科研创新和提升种植规划水平等建议,以期进一步优化我国糖料蔗种植品种结构,提高产业经济效益和社会效益。
