为了探讨麦桐套种共生期间,地膜覆盖育泡桐苗对苗木生长的影响。我们于1984年春分别在城关镇和马厂、独塘乡进行了麦桐套种地膜覆盖育苗试验,均取得良好效果。现将城关镇的试验情况初报如下: 一、试验材料和方法试验地在太康县城关镇,面积4.2亩,粘壤土,地下水位3.5米,土壤肥力中等。小麦播种前,每亩施农家肥3立方米,碳酸氢铵45公斤,过磷酸钙40公斤;翌春4月1日育苗带整地,每亩施复合肥30公斤。供试材料:一年生豫杂一号泡桐苗根和宝丰7228小麦。配置方式:播4行小麦(占地70
In order to investigate the symbiosis of wheat tress intercropping, the effects of mulching Paulownia seedlings on seedling growth were studied. In the spring of 1984, we conducted the test of plastic film mulching and seedling cultivation of wheat tree intercropping in Chengguan Town, Ma Chang and Dadang Township, all of which achieved good results. First, the test materials and methods to test the Chengguan Town in Taikang County, an area of 4.2 acres, clay loam, groundwater level of 3.5 meters, medium fertility. Prior to sowing the wheat, 3 mu of farmhouse manure, 45 kg of ammonium bicarbonate and 40 kg of superphosphate were applied per acre. On April 1, the nursery belt was sown next spring on April 1, and 30 kg of compound fertilizer was applied per acre. Materials for the test: an annual hybrid Yu Mi Paulownia seedlings and Baofeng 7228 wheat. Configuration: 4 lines sowing wheat (covering 70
