一、依据当地的气候条件选用熟期适宜的品种目前,吉林省栽培的玉米、大豆品种生育期都较偏晚,部分农民忽视当地具体条件盲目种植一些晚熟高产品种,助长了冷害的发生。同时,生产的商品玉米水分含量高,成熟度差,影响贮藏和销售;而生产的商品大豆因贪青晚熟,严重地影响了产量和品质。因此,要因地制宜,合理选用玉米、大豆优良品种,使其特征特性与本地区的气候条件相适应。二、依据土壤肥力和栽培条件选用适宜品种生产上应根据当地的土质、地势、地力、施肥水平、栽培方法等选用适宜的品种,以获得丰产增收。
First, according to the local climatic conditions, select the appropriate maturity varieties At present, Jilin Province, corn and soybean cultivars grown more late, some farmers ignore the specific conditions of blind planting some late-maturing high-yield varieties, contributed to the occurrence of chilling injury. At the same time, the production of corn high moisture content, poor maturity, affecting the storage and sale; and the production of soybean due to greyish late, seriously affecting the yield and quality. Therefore, according to local conditions, the rational use of corn, soybean varieties to make its characteristic characteristics and the climatic conditions in the region to adapt. Second, according to soil fertility and selection of suitable varieties of cultivation conditions should be based on the production of local soil, topography, fertility, fertilization levels, cultivation methods such as the selection of suitable varieties in order to obtain high yield.
