一、前言一九六三年省园艺所以山葡萄做砧木芽接栽培品种葡萄试验成功后,为葡萄在我省真正安家落户和大面积发展奠定了基础。在目前生产上确立了必须以山葡萄作砧木才能保证安全越冬和获得最好产量。加上采取立架密植方式,每个主蔓较短、单株产量要求不高。在这种要求下,根系分布在2.5米以内是完全可以达到植株生长和结果要求的。这样就设想了行距3米的立架密植方式。经过八年生产实践证明这样的行距是完全有把握和效果良好的。 I. Introduction In 1963, after the successful test of the grapes from the grapevine rootstocks planted in the provincial horticultural province, the grapes laid a solid foundation for the grapes in our province to truly settle down and develop in a large area. In the current production established must grapevine rootstocks to ensure the safety of winter and get the best output. In addition, we adopt the method of vertical frame planting and each main vine has a short length, and the yield per plant is not high. Under such a requirement, the distribution of the root system within 2.5 meters is fully able to meet the requirements of plant growth and results. This assumes that the vertical spacing of 3 meters row close planting way. After eight years of production practice has proved that such a line spacing is completely sure and good results.
