黑龙江地区属我国北方早熟春玉米产区,其中第二、三积温带分布较广,生态类型较复杂,这一区域的气候特点是气温低、降雨少、多春旱春寒(不利于出苗和保全苗)、秋早霜(不利于玉米成熟和籽粒脱水)。该产区玉米的主要病害为大斑病、丝黑穗病和茎腐病。要求玉米抗旱、耐寒、籽粒脱水速度快、优质、抗病、高产品种应用于生产。
Heilongjiang area belongs to the early maturing spring maize producing area in northern China, of which the second and the third accumulate temperate zone are widely distributed and the ecotypes are complex. The climate in this area is characterized by low temperature, less rainfall, more spring and cold in spring (not conducive to emergence and preservation Miao), early autumn frost (detrimental to corn and grain dehydration). The main maize diseases in the producing area are big spot disease, head smut and stalk rot disease. Requires corn drought, cold, dehydration speed, high quality, disease resistance, high yield varieties used in the production.
