测算作物田间密度是掌握和诊断作物生长状况和田间产量的重要依据,传统的测算方法是田间取点测查后,按公式计算:亩密度=666.67m~2/平均行距×平均穴距×穴平均苗(穗)数 此法田间取点要求高、测查工作量大、测查结果小数多计算麻烦。在多年的实践中,我们总结出一个作物田间密度快测算法,它广泛适用于行条播
Calculating the field density of crops is an important basis for grasping and diagnosing crop growth status and field yield. The traditional calculation method is to take a field survey and calculate according to the formula: Mu density = 666.67m ~ 2 / average spacing × average hole distance × hole The average number of seedlings (spike) This method to take the field of high demand points, test workload, the test results decimal calculation more trouble. In many years of practice, we summarize a crop field density fast test algorithm, which is widely used in row planting
