摘要
随着全球气温的升高,黑河地区的气温也逐年升高,干旱情况逐年加重,特别是最近几年温度升高有加快之势。农民越区种植的情况很多,种植的品种多、乱、杂且种植密度较低影响产量,在种植过程中存在管理粗放、随意性大等问题。为此,黑龙江省农业科学院黑河分院在2009～2010年进行了品种鉴选试验,初步筛选出符合各积温带种植的品种德美亚2号、德美亚1号、垦单8号、边三2号与克单9号;并提出适合于当地的栽培方法,以提高玉米产量。
As the global temperature rising,the temperature in the region of Heihe increases year by year and the drought is aggravates and especially in recent years temperature has a trend of rise.Too many varieties being chosen randomly by farmers and the low planting density affect the yield,extensive management and growing randomly exist in the process of growing,so Heihe Branch of Heilongjiang Academy of Agricultural Sciences performed an experiment on variety selection between 2009 and 2010 by which the varieties Demeiya No.2,Demeiya No.1,Kendan No.8,Biansan No.2,Kedan No.9,suitable for growing in different accumulated temperatures were screened preliminarily and the cultivation methods suitable for the region were put forward in order to improve the maize production.
