为解决旱坡地杂交高粱捉苗难的问题,1983年我们从山西省农科院品种资源所引回长根茎晋杂5号高梁品种,进行播深试验.长根茎晋杂5号种子发芽率97%。设播深3寸、1.5寸两个处理。普通晋杂5号(发芽率95%)播深1.5寸为对照。小区面积0.01亩,每小区播10行,行长2.4米,每行播种45粒。播种时0—15厘米土壤含水量为11.7%。各处理于5月2日同时播种。长根茎晋杂5号播深3寸的5月12日开始出苗,5月14日出齐,出苗期仅3天;播深1.5寸的和普通晋杂5号5月13日开始出苗,5月25日
In order to solve the difficult problem of hybrid sorghum harvesting in dryland, 1983, we introduced the sorghum variety Jinza No.5 from Shanxi Academy of Agricultural Sciences and conducted sowing experiments. The germination rate of Jingan 5 %. Set sowing depth 3 inches, 1.5 inches two processing. General Jin hybrid 5 (germination rate 95%) sowing 1.5-inch as a control. Residential area of 0.01 acres, 10 per cell broadcast line, governor 2.4 meters, 45 lines sowing. 0-15 cm soil moisture at planting is 11.7%. All treatments were sown at the same time on May 2. Long roots Jin hybrid 5 sowing depth 3-inch May 12 began to emerge, May 14 altogether, only three days of seedling; sowing 1.5-inch and ordinary Jinza 5 on May 13 began to emerge, 5 On the 25th
