枸杞在未形成树冠的幼龄期,产果量和经济效益较低,宁夏枸杞的栽培一直沿用传统栽植方式,不适应生产发展的需要。本试验对幼龄期不同密度的栽植方式进行了试验,目的在于探讨最适栽植密度和最大经济效益,为发挥宁夏地方特产优势提供理论依据。一、试验地自然概况试验设在芦花台园林场,地处银川市西北郊,海拔1119米;年均温7.7℃,1月份均温-10.3℃,7月均温23.2℃,年温差15.3℃;初霜期10月上旬,终霜期5月上旬,无霜期154天;年降水量150毫米,年蒸发量2700毫米,全年日照时数3100小时,土壤属淡灰钙土,地下水埋深1米。在0～
Wolfberry in the formation of the canopy of young, low yield and economic benefits, Ningxia wolfberry cultivation has been using traditional methods of planting, does not meet the needs of the development of production. In this experiment, different density planting methods of young age were tested, the purpose is to explore the optimal planting density and maximum economic benefits, to provide a theoretical basis for the advantages of Ningxia local specialty. First, the experimental nature of the general test site located in Luhuatai garden, is located in Yinchuan City, northwestern suburbs, 1119 meters above sea level; average annual temperature of 7.7 ℃, January average temperature - 10.3 ℃, July average temperature of 23.2 ℃, annual temperature difference of 15.3 ℃; early frost Early October, the end of early frost in early May, frost-free period 154 days; annual rainfall of 150 mm, the annual evaporation of 2700 mm, annual sunshine hours 3100 hours, the soil is light gray earth, groundwater depth of 1 meter .
