Utilization of Agricultural Climatic Resources under the Spring Maize-Spring Potato Intercropping Pattern in Pengzhou City

According to the meteorological requirements of maize and potato,using the data of meteorological observations and soil moisture of Pengzhou City,the agricultural climatic resources of spring maize and spring potato planting and the advantages of agricultural climatic resources of their intercropping were analyzed. The suitable sowing dates for spring maize and spring potato are late March to early April,early February to early March,respectively. During the growth period,the heat resources are abundant,the soil moisture is sufficient,the precipitation and overall distribution are suitable,and the sunshine is still sufficient,which can meet the needs of each growth period. The overall configuration of agricultural meteorological resources is coordinated,which is suitable for the planting of the two. Spring maize-spring potato intercropping can make the most of land,time and space,improve light and heat utilization,reduce pests and diseases,and increase output per unit area,thereby maximizing economic benefits.
