近年来,川西盆周阴湿多雨丘陵地区,由于粮、油产量波动较大,引起了人们在小春格局上的疑虑。针对这个问题,作者从作物产量是作物群体与环境条件相互作用的结果,是农田生态经济效益的重要表现形式的认识出发,选取了名山县近8年麦、油产量资料,结合田间考查,采用数理统计的方法,分析了该地区两作物的产量稳定性,比较了经济效益,提出对策并进行讨论。现将结果整理如下:产量稳定性分析
In recent years, the humid and rainy hilly areas in the basin basin of western Sichuan have aroused people’s suspicion in the pattern of the small spring due to the volatile fluctuations of grain and oil production. In response to this problem, the author from crop yield is the result of the interaction between crop groups and environmental conditions, is an important manifestation of ecological and economic benefits of farmland starting from the selection of Mingshan last 8 years of wheat and oil production data, combined with field tests, using Mathematical statistics method, the output stability of two crops in the area was analyzed, the economic benefits were compared, the countermeasures were put forward and discussed. The results are now organized as follows: Yield stability analysis
