为了预测和评估2014年柳州、来宾蔗区甘蔗生产情况,采用实地调查和数据收集相结合的方法,调查了两个蔗区甘蔗苗情、品种结构、种植面积等。调查结果表明:2014年柳州、来宾蔗区糖料蔗苗情比上年差,甘蔗种植迟,植株矮,苗数比上年少或相当。来宾蔗区的总体苗情和长势比柳州好。两个蔗区的螟害发生率较低,无重大自然灾害和病虫害。两个蔗区的甘蔗种植面积大幅度减少。两个蔗区的品种结构有所改善,但仍需进一步促进品种结构合理化,尤其是宿根性表现好的桂糖系列甘蔗新品种的推广。
In order to predict and evaluate the sugarcane production in the sugarcane planting area of Liuzhou in 2014, a combination of field survey and data collection was used to investigate the sugarcane seedling, variety structure and planting area in two sugarcane growing areas. The survey results show that in 2014, the sugarcane seedlings in sugarcane planting area in Liuzhou were worse than the previous year, the sugarcane planting was delayed, the plants were short and the number of seedlings was less or equal than the previous year. The overall growth of guest cane area and growing better than Liuzhou. The incidence of stem borers was lower in the two sugarcane areas without major natural disasters and pests and diseases. Sugarcane acreage in the two sugarcane areas decreased significantly. The varieties structure of the two sugarcane areas improved, but the varieties structure should be further rationalized, especially the promotion of new varieties of sugarcane with good rooting performance.
