油桃在温室载培是一种高密度集约化栽培形式,适当的密度与树形是获得高产优质的关键。为给生产者提供科学依据,1997年—1999年我们根据温室结构及气候特点,针对密度与树形进行了研究,现将试验结果报告如下。 1 材料与方法 (1)栽植密度试验 试验区设在大庆果园,温室长55m,跨度6.5m,脊高3.2m,墙体为红砖外37cm、内24cm,中间12cm空心加保温板。钢筋骨 Nectarine cultivation in the greenhouse is a high density intensive cultivation form, the appropriate density and the tree is the key to high yield and quality. In order to provide scientific basis for producers, we conducted a study on density and tree shape based on the characteristics of greenhouse structure and climate from 1997 to 1999. The test results are reported as follows. 1 Materials and Methods (1) Planting Density Test The experimental area is set in Daqing Orchard. The greenhouse is 55m long with a span of 6.5m and a ridge height of 3.2m. The wall is made of 37cm red brick, 24cm inside and 12cm hollow insulation board in the middle. Steel bones
