襄汾县贾罕乡现有林粮间作田6000多亩,占全乡水地面积的23.6％;襄汾县现有林粮间作田8万余亩,越是好地水地植树越多。大面积的林粮间作,已成为晋南部分小麦产区影响粮食产量的主要因素。为了给各级有关领导进行农业生产决策提供科学依据,我们就林粮间作对小麦的生理、生态、土壤养分、水分及子粒产最的影响进行了比较系统的分析研究。
Xiangfen County, Jia Han existing intercropping forest farmland for more than 6,000 acres, accounting for 23.6% of the township water area; Xiangfen County existing intercropping of more than 80,000 acres of fields, the better the more water to tree planting. Large-scale intercropping of forest and grain has become the main factor affecting the grain yield of some wheat growing areas in southern Shanxi. In order to provide a scientific basis for leaders at all levels to make decisions on agricultural production, we conducted a systematic analysis of the impact of intercropping on the physiology, ecology, soil nutrients, moisture and grain yield of wheat.
