为了鉴定新选育的玉米新品种在我地区的适应性、丰产性和抗逆性,科学确定2014年玉米主推品种提供科学依据,特安排本试验。1试验基本情况1.1参试品种参试品种共有6个:苏玉20(对照)、苏玉22、苏玉29、苏玉30、中江玉6号、长江玉6号。承试单位:四甲农技站、万年农技站、三厂农技站。1.2试验设计本试验设置3个试点,每个试点设二次重复,与蚕豆套作。理论密度60 000株/hm2,实际密度为四甲57 855株/hm2、万年49 380株/hm2、三厂58 980株/hm2。采用随机区组排列,试验四周种植保护行,同品种延伸。
In order to identify the adaptability, high yield and stress resistance of newly maize new varieties in our region, it is scientifically determined to provide the scientific basis for the main varieties of maize in 2014, and this experiment is specially arranged. 1 The basic situation of the test 1.1 The test varieties A total of six varieties tested: Su Yu 20 (control), Su Yu 22, Su Yu 29, Su Yu 30, Zhongjiang Yu 6, Yujiang No. 6. Undertaking units: Sijia agricultural station, ten thousand years agricultural station, three farm station. 1.2 Experimental Design The experiment set up three pilot, each experimental set repeated twice, with broad bean set for. The theoretical density of 60 000 plants / hm2, the actual density of Sikai 57 855 plants / hm2, years 49 380 plants / hm2, three plants 58 980 plants / hm2. Using random block arrangement, four weeks of planting protection line, the same species extension.
