摘要
本文在推导出播种粒距数学模型的基础上,应用蒙特卡洛方法,分别进行了播种粒距、出菌株距和间苗后定苗株距的电子计算机模拟,在 PC—1500型及 Apple—Ⅰ型微机上打印出运算结果和以上三种情况的直方图和频次表。从而求出植株田间分布的规律和播种时合理的调整株距。文中介绍的方法,曾应用于辽宁省重点攻关项目——精密播种综合技术措施的研究。达到了较理想的植株密度,保证了实际需要的田间保苗率。
Based on the mathematical model of seed spacing developed by the authours, using Monte-Carlo Method,the paper made computer simulation of seed spacing, plant spacing and setting spacing,produced a histogram and a frequency table for three different situations with Computer PC-1500,and derived the pattern of plant spacing and the reasonable adjusted seed spacing. The approach has been used in a major research project of Liaoning province--A study on comprehensive techniques for precision drilling.The result is coincided with the plant density acually expected.
