Abstract

Using the staged sowing experiment data and rice quality data of the specialized forage rice "Zhongzao 39"(hereinafter referred to as "Z-39") conducted in Nanning, Guangxi, combined with climate and geographic information data, the meteorological factors that play a key role in the formation of rice quality for the specialized forage rice "Z-39" are screened and determined. Based on the actual planting of specialize forage rice in Guangxi and the critical disaster causing indicators of "Z-39" specialize forage rice, the climate quality zoning index of "Z-39" is determined. GIS fine grid spatial simulation analysis method is used for refined spatial simulation analysis on key meteorological factors. The zoning indicator method and path analysis method are fully used for refined level zoning of the climate quality of Guangxi specialized forage rice "Z-39". It includes three levels: optimal, high-quality, and suboptimal. Ultimately, a refined zoning map for the climate quality of "Z-39" is developed, and the results are in line with the actual situation of forage rice cultivation in Guangxi. The aim is to provide a scientific basis for the rational planning and sustainable development of the specialized forage rice "Z-39" in Guangxi.

Abstract in Chinese

利用在广西南宁开展的专用饲料稻“中早39”分期播种试验数据以及稻米品质数据,结合气候资料和地理信息数据,筛选确定对专用饲料稻“中早39”稻米品质形成起关键作用的气象因子,结合广西专用饲料稻实际种植情况以及专用饲料稻“中早39”致灾临界指标等,确定“中早39”气候品质区划等级指标,并利用GIS细网格空间模拟分析方法对关键气象因子进行精细化空间模拟分析,综合利用区划指标及通径分析法,对广西专用饲料稻“中早39”气候品质进行最优、优质和次优三个等级的精细化等级区划,研制出广西专用饲料稻“中早39”稻米气候品质精细化区划图,分区结果符合广西饲料稻种植实际情况,以期为专用饲料稻“中早39”在广西种植提供合理规划布局和可持续发展提供科学依据。
