水稻是榆树市主要农作物之一,面积4万多公顷。近年来随着科学技术的进步和生产水平的提高,水稻产量逐年增加,但发展不平衡,高产地块9000kg/hm2以上,低产地块仅6000kg/hm2。经调查研究,这些低产地块除土壤条件不良外,与农民选择品种不合理、育苗技术不规范、插秧晚、肥水管理不当等有关。实践证明,合理选用优良品种,全面推广水稻先进栽培技术是提高水稻产量和增加经济效益的关键。
Rice is one of the main crops in Yushu City, covering an area of more than 40,000 hectares. In recent years, with the advancement of science and technology and the improvement of production level, the output of rice has been increasing year by year, but the development is uneven. The yield of high-yielding land is over 9,000kg / hm2 and that of low-yielding land is only 6,000kg / hm2. After investigation, these low-yielding plots except for poor soil conditions, and farmers choose varieties unreasonable, nursery non-standard technology, planting late, improper management of fertilizer and other related. Practice has proved that the rational selection of good varieties and comprehensive promotion of advanced rice cultivation techniques are the key to increasing rice yield and increasing economic benefits.
