In order to find out the adaptability of “Minyou 128” in the climate conditions of our county, perennial annual temperature of 3804 ℃ and sunshine duration of 1204.1 hours were obtained from May 20 to October 20, and the main economic traits and growth dynamics were grasped to seek high-yielding cultivation Way, in 1998 in Daidong Town, Tiger Village conducted a large area product testing, nitrogen fertilizer and sowing date. 1 Experimental Design 1.1 Large-scale product ratio test The tested varieties “Minyou 128”, “Qiouyou 7” and “Hanyouxiangqing” have a large area of 2.7 mu. There are no repetitions, medium fertility and no blank before. Base fertilizer Mushi carbon hinge 50kg, superphosphate 25kg, potassium chloride 10kg, June 29 topdressing urea 7.5kg. Unite
