我区种植的棉花品种,以春播中熟的陕1155、陕401为主。早熟棉花品种黑山棉、6913、中棉10号相继引进后,多数用作夏播,少数用作春播。为了探索不同熟性棉花品种春夏播的生育状况、抗病性及产量品质等问题,进而为选育适应本地区栽培的理想品种提供依据,我们于1981—82年进行了试验研究,结果如下。一、材料与方法供试品种:1981年春、夏品种有早熟种黑山棉、6913、中早熟品系 6083(本所从SR—
The cotton varieties planted in our district are mainly Shaanxi 1155 and Shaanxi 401, which are medium-sown in spring. Early cotton varieties Montenegro cotton, 6913, China cotton 10 have been introduced, the majority of summer sowing, a few for spring planting. In order to explore the fertility, disease resistance, yield and quality of spring and summer sowing varieties of different varieties of cotton, and to provide the basis for breeding ideal varieties suitable for cultivation in this region, we conducted the experimental study in 1981-82 with the following results . First, the material and methods to test the varieties: the spring of 1981, the early varieties of summer varieties of Montenegro cotton, 6913, 6083 in the early maturing line (the firm from the SR-
