摘　　要：在核桃和小麦间作地块,采取核桃雄花开始发育前疏除部分雄花芽,核桃雌化盛期喷施0.3%尿素和0.3%硼酸,以及疏除部分雄花和花期喷肥同时处理几项管理措施的试验结果表明:核桃的产量、平均单果重等都有不同程度的变化,总体趋势是平均单果重与对照相比稍有减小,产量有所提高,其中去除雄花和花期喷肥都处理的产量提高效果最明显。In walnut and wheat intercropping land parcel, in male flowers, before starting to develop thin walnut male flower bud, except the part in walnut spraying 0. 3% urea and 0. 3% boric acid from the feminisation stage and removing walnut part of male flowers and flowering spray fertilizer processing at the same time. The results showed that walnut yield, average fruit weight and so on all have different degree of change, the overall trend is the average fruit weight compared with the contrast slightly decreases, and yield improvement, including removal of male flowers and flowering fertilizer spraying processing production increase effect was the most obvious.
