黑龙江垦区是我国重要的商品大豆生产基地之一,但亩产长期处于低而不稳的状况。 大豆高产栽培开发研究,用系统观点,从环境条件、农艺措施和大豆生长发育的相互关联中,分析了大豆单产低而不稳的原因;用系统工程方法,依据各地生态特点,气象条件的变化,综合组装农艺措施,突破限制因素,有效地发挥了自然资源优势和技术措施的增产潜力;用回归设计方法,试验优化了各生态区主要品种的高产农艺组合。 通过三年在不同地区,不同气候条件下的大规模试验,使六个中产变高产基点亩产达到350—400斤,比前三年平均亩产提高75.1％;三个低产变中产基点亩产达到250斤左右,增产1.27倍。
Heilongjiang reclamation area is one of the important commodity soybean production bases in our country, but the long-term yield per mu is in a low and unstable state. From high-yielding and high-yield cultivation of soybean, we systematically analyzed the causes of low and unstable yields of soybean from the interrelationship of environmental conditions, agronomic practices and growth and development of soybeans. Using systematic engineering methods, based on the ecological characteristics and the changes of meteorological conditions , Integrated agronomic measures to break through the limiting factors, effectively giving play to the potentials for increasing natural resources and technical measures, and using the regression design method to optimize and optimize the high-yield agronomic mix of the main varieties in each ecological zone. After three years of large-scale tests in different regions and climates, the output of six middle-yielding high-yield bases reached 350-400 kg per mu, an increase of 75.1% over the previous three years. Three low-yielding medium-yielding plots per mu Reached 250 pounds, an increase of 1.27 times.
