苹果高接换头早结果技术,是我县发展苹果生产的主要技术措施。它具有抗寒、抗病虫、抗越冬抽条、结果早的特点。适合于苹果新育品种、新引进品种的繁殖。几年来,我们通过老苹果园高接换头早结果技术发展苹果生产,解决了苹果冻害、越冬抽条和结果迟这一难题。为指导大面积推广提供依据。 一、试验材料与方法 试验设在金塔县中东镇三湾沟三队,海拔1270.2米,年平均气温8℃,平均无霜期141天,年降雨量59.9毫米,蒸发量2538.6毫米,平均风速3米/秒,土壤为
Apple high replacement early results technology, is the development of our county Apple’s main technical measures. It has the characteristics of cold-resistant, pest-resistant, anti-wintering, early results. Suitable for apple breeding, the introduction of new varieties of breeding. Over the past few years, we have adopted the old apple orchard exchange early results of technology to develop Apple production, solve the apple frost damage, overwintering pumping and the results of this problem. To guide the promotion of large-scale provide the basis. First, the test materials and methods The test is located in the three teams in Sanwangou, Middle East Town, Jinta County, with an elevation of 1270.2 meters and an annual average temperature of 8 degrees Celsius. The average frost-free period is 141 days with an annual rainfall of 59.9 millimeters, an evaporation of 2538.6 millimeters and an average wind speed of 3 meters / Second, the soil is
