Advanced experiences from developed countries were adopted by Heilongjiang Academy of Agricultural Sciences when seeking for the solutions on expanding production and promoting transformation of agricultural production mode across the province.Methods and means on system engineering were applied by the academy, which played a leading role in implementation of agricultural science and technology innovation projects and technological transformation projects as well as promoting engineering agriculture. Not only was a fundamental change in agricultural development enhanced, but also was a practical and effective way on modern agriculture development revealed. Rate of agricultural scientific and technological achievements was raised from 30 % in 2003 to 70 % in 2010; coverage of improved varieties increased from 90 % to 98 %; agricultural science and technology contribution rate climbed from 48.5 % to 59.5 %; food production increased from 25.1 25 billion kg to 50.13 billion kg, accounting for 1/10 of total grain output and commodity rate accounting for 1/3 of the total amount of food in China, which was a significant contribution in national food security.
