在本刊2001年第三期上我们对优质砂梨新品种作了介绍,现概述其丰产栽培技术如下。1.高标准建园梨树适应性较强,对气候、海拔、土壤等条件要求不严,但以土壤疏松,土层深厚,有机质丰富的土地为佳。在平整土地后,按2～3米×3～4米的株行距挖定植穴,定植穴长度、宽度和深度各为1.0米、1.0米和0.6米。定植穴底部先填入表土或好的客土,再在距地表30～50厘米处填入与有机肥混匀的表土(每穴50千克有机肥加1千克磷肥),表层填入行间的表土或破碎后的心土,堆成丘状。
In the third issue of 2001, we introduced the new varieties of fine sand pear, now outlined its high yield cultivation techniques are as follows. 1. High standards Jiangyu pear tree adaptability, on the climate, elevation, soil and other conditions lax, but the soil is loose, deep soil, organic matter rich land is better. After the land is formed, the planting holes are excavated according to the row spacing of 2 ~ 3m × 3 ~ 4m. The length, width and depth of the planting holes are 1.0m, 1.0m and 0.6m respectively. Top of the planting hole filled with topsoil or good soil, and then fill the topsoil (50 kg of organic fertilizer plus 1 kg of phosphate fertilizer per hole) filled with organic fertilizer 30 to 50 cm from the surface, Topsoil or broken heart, piled into mound.
