黑龙江省玉米播种面积在3500万亩左右,占作物播种面积的30%。目前,我国已加入 WTO,种植结构调整速度加快,但玉米作为本省重主栽品种和具有重要地位的现实情况仍未改变。因此,从种植面积的生产地位上看,搞好玉米生产是关键、也是实现农民“入世”后发展玉米生产的重要途径。针对玉米生产中影响产量和品质的制约因素,近年来,开发玉米通透栽培技术,已达到技术完善、丰富了技术内涵,2001年此项技术被省农委列为全省农业十大重点推广项目。当年推广面积达256万亩,亩增产49.1公斤,降低含水量3～5个百分点,新增总产值1亿多元;因效果显著,该项目2002年被列为全省重点推广项目。因此,此项技术对实现农民增效增收是一条致富的新路。
The sown area of corn in Heilongjiang Province is about 35 million mu, accounting for 30% of the sown area of crops. At present, China has acceded to the WTO and the pace of planting and structural adjustment is accelerating. However, the reality that corn, as a major cultivated variety in the province, has an important place remains unchanged. Therefore, from the perspective of the production status of the planting area, improving corn production is the key and also an important way to realize the development of corn production after farmers join the WTO. In view of the restrictive factors affecting the yield and quality of corn production, in recent years, the development of corn transparent cultivation technology has achieved technological improvements and enriched the technical connotation. In 2001, this technology was listed as one of the ten major agricultural promotion projects by the Provincial Commission of Agriculture project. In the same year, the area of popularization reached 256 mu, yielding 49.1 kilograms of mu and reducing the water content by 3 to 5 percentage points, with a total output value of over 100 million yuan. Due to the remarkable effect, the project was listed as a key promotion project of the province in 2002. Therefore, this technology is a new way to increase profits for farmers.
