一、整地玉米属高杆作物,根系发达,需肥水较多,要获得高产就需要土层深厚、肥沃、疏松,因此,玉米地要早犁早耙,多犁多耙,做到土质松软,细碎平整。二、品种选择根据前茬种植选种。品种玉米的增产增收与前茬种植有直接关系。若前茬种植的是大豆,土壤肥力则较好,宜选择高产品种;若前茬种植的是玉米,且生长良好、丰产,可继续选种这一品种;若前茬玉米感染某种病害,选种时应避开易染此病的品种。另外,同一个品种不能在同一地块连续种 First, the whole field of maize is a high bar crop, root system developed, need more fertilizer, to obtain high yield on the need for deep soil, fertile, loose, so early to harrow the corn harrow, more plow and more rake, so soft soil, Fine and smooth. Second, the selection of varieties According to the former crop planting selection. Production and income of varieties of corn is directly related to the cultivation of the former crop. If the former crop is planted in soybeans, soil fertility is better, should choose high-yielding varieties; if the former crop is planted with corn, and good growth, high yield, can continue to choose this variety; if the former crop of corn infected with a disease, Variety should be avoided when the species susceptible to the disease. In addition, the same species can not be continuous species in the same land
