六、把试验管理好为使试验处理进行精确可靠的比较,试验地的田间管理有两个基本要求:1.代表性、先进性:各项管理措施,如追肥、灌水、中耕等,必须及时细致.应根据当地大面积丰产田的水平,采用最先进的技术措施.要不误农时.倘若试验操作粗放,管理不及时,便不能正确反映新品种或新技术在今后推广时所能达到的增产效果.有时为鉴定新品种的抗逆性,也可特设试验,有意识地给以严酷的管理条件,考验其抗寒性、抗旱性等.2.均匀一致性:同一试验的管理工作,除试验处理外,要同时、同质、同量,达到均匀一致,避免人为的原因而影响试验的精确性.各项管理作业应在同一天内完成,若时间不允许,要使一个重复的工作在同一天作完.一项作业可由一人负责全试验,或一人负责一个重复,若试验面积大,可几个人在同一试验区内工作,以求质量相同.打药或混施几种肥料时,要混拌均匀.追肥等需要计算用量的项目,应按单位面积和试验区面积的比例,准确计算各区用量,不可大略估计,以免造成用量不等.
Sixth, the test management In order to make the experimental treatment of accurate and reliable comparison, experimental field management has two basic requirements: 1. Representative, advanced: various management measures, such as fertilizer, irrigation, cultivation, etc., must be timely Should be based on the level of the local large area of high yield fields, the use of state-of-the-art technical measures.Or farming, if the extensive test operations, management is not timely, they can not correctly reflect the new varieties or new technologies can be achieved in the future promotion Increase production effect.Often to identify the resistance of new varieties, but also ad hoc experiments, consciously give harsh management conditions, test its cold resistance, drought resistance, etc. 2. Uniformity: the same test management, In addition to the test treatment, to be homogeneous, homogeneous, the same amount, to achieve uniform, to avoid human factors that affect the accuracy of the test. The management operations should be completed in the same day, if the time is not allowed to make a duplication of work On the same day, a work can be a full person responsible for the test, or a person responsible for a repeat, if the test area is large, several people in the same test area work in order to seek the same quality. Should be mixed evenly.Application of fertilizer and other need to calculate the amount of the project should be the unit area and test area area ratio, accurate calculation of the amount of each district, can not be roughly estimated, so as not to cause the dosage range.
