为了探索淮北地区大面积提高棉花产量的途径,我们于1981～1986年在本场对不同产量水平棉花的生育规律及栽培措施进行了系统调查与分析。调查对象为泗棉2号及麦套移栽棉种植方式。6年中先后调查了高产田45块,共99亩,平均亩产皮棉105.0公斤;中产田5块,共11.23亩,平均亩产皮棉80.1公斤;低产田5块,共11.67亩,平均亩产皮棉53.9公斤(与淮北棉区大面积产量水平相同)。现将结果报道如下。
In order to explore a large area of Huaibei area to increase cotton production ways, we in 1981 to 1986 in this field on the yield of different levels of cotton’s reproductive system and cultivation measures were systematically investigated and analyzed. The investigation object is Simian 2 and wheat transplanting cotton planting methods. In the past six years, 45 high-yield fields were surveyed, with a total area of 99 mu and an average of 105.0 kg of lint per mu. There were 5 middle-yielding fields with a total area of 11.23 mu and an average of 80.1 kg of lint per mu; and 5 low-yield fields with a total of 11.67 mu Lint 53.9 kg (with large area of Huaibei cotton production level the same). The results are reported below.
