玉米是建平县主要粮谷作物之一,全县的山地、坡地、平地都种有玉米.由于土壤肥力不同,气候因素复杂,生产条件和技术措施差异较大,全县玉米产量形成了三种类型,即高产稳产,高而不稳,不高不稳.我们在总结群众经验的基础上,进行了若干玉米生物学指标的测定和研究,为制定玉米增产措施提供科学依据.
Corn is one of the main cereal crops in Jianping County, and corn is planted in mountainous, sloping and plain areas of the county.Because of different soil fertility and complicated climatic factors, the production conditions and technical measures are quite different. The yield of corn in the county has formed three That is, high and stable yield, high and unstable, not high and unstable.We conducted a number of maize biological indicators on the basis of summing up the experience of the masses, and provide scientific evidence for the development of measures to increase corn yield.
