晴空万里,东边出现一道彩虹。看,DYP—416型喷灌机(见图)正在浇小麦地。该机于去年已初步定型,它是由广西水轮泵研究所、南宁水稻插秧机厂和柳州市电器二厂共同研制的。该机定点控制面积达920亩,折合亩投资70～80元,比地面灌省水30～60%,使用寿命约15年,一般可在四年左右收回成本。自动化程度较高,可自动作业,每班只需一人监视仪表即可。当地形坡度不超过20%时,仍可照常工作。装 Clear sky, there is a rainbow on the east. Look, DYP-416 type irrigation machine (see picture) is pouring wheat field. The aircraft was initially finalized last year, it is co-developed by Guangxi Institute of Hydro-pump, Nanning rice transplanter plant and Liuzhou Electric Appliance Factory jointly developed. The aircraft fixed-point control area of ​​920 acres, equivalent to 70-80 yuan investment in mu, than the provincial irrigation water 30 to 60%, the service life of about 15 years, usually about four years to recover the cost. High degree of automation, automatic operation, only one monitor per class can be. When the terrain gradient does not exceed 20%, still can work as usual. Loaded
