由于晚茬麦播种晚,分蘗少,生长势弱,形成三类苗。为了促使三类苗转化升级,我们采取了二锄、三肥、五水节节促进的管理措施。3月中旬锄地松土、清垅、扶埂,提高地温,促进麦苗早返青、生根、增蘗、快长。4月24日第二次中耕松土,改善土壤通气条件,促进根系发育。3月上、中旬,趁墒追第一次肥,每亩用七行畜力条播机施硫铵20斤;4月18日追第二次肥,每亩施尿素20斤;5月8日追第三次肥,
Due to the late sowing of late crop of wheat, less tillers, weak growth, the formation of three types of seedlings. In order to promote transformation and upgrading of the three types of seedlings, we adopted two hoe, three fat, Wu Si festival promotion of management measures. In mid-March hoe to loose soil, clear water, Fuzao, increase ground temperature, promote wheat seedlings early green, rooting, tillering, fast growth. April 24 The second cultivating loose soil, improve soil aeration conditions and promote root development. In March, middle and mid-winter, while pursuing the first fertilizer with the soil moisture, seven acres of animal power drill was used to apply ammonium sulphate to 20 kilos; April 18 to catch the second fertilizer, 20 kilograms of urea per mu; May 8 The third fat,
