武威市城郊海拔1531米,无霜期155天,全年有效积温(≥10℃)3077℃,早霜期为10月7日左右,晚霜期为4月15日左右。为了加快西瓜育种速度,1990～1991两年我们在武威市城郊进行了西瓜加代繁育试验,1990年上代为地膜覆盖加小拱棚早熟栽培,下代为露地栽培和室内盆栽,露地栽培由于9月下旬夜温较低,使西瓜冻裂而未成功,室内盆栽取得成功,获得了两份加代材料。1991年在1990年的基础上,总结经验教训,加代繁育成功。现将栽培技术介绍如下。一、上代种植方法1.播前准备:播前将地平好,亩施5000～8000
Wuwei City suburb elevation of 1531 meters, frost-free period of 155 days, the effective accumulated temperature (≥ 10 ℃) 3077 ℃, the early frost period is about October 7, the night frost period is April 15 or so. In order to speed up the speed of watermelon breeding, 1990 ~ 1991 two years in Wuwei City, we conducted a watermelon plus breeding test, the previous generation of plastic mulching in 1990 plus a small shed early cultivation, the next generation of open-field cultivation and indoor potted plants, open field cultivation As late September night Lower temperature, watermelon cracked without success, indoor potted success, obtained two plus Canadian materials. In 1991 on the basis of 1990, lessons learned, plus the success of breeding. Now cultivation techniques are as follows. First, the method of planting the previous generation 1. Prepare before sowing: before sowing will be good, Mushi 5000 ~ 8000
