If I were given an opportunity by the society, I can write another edition of road map about development of science and technology for China. Firstly, I should suggest to the national departments concerned that“popularization of artificial soil technology and development of artificial soil industry”be taken as the basic national policy and using this technology the agricultural problem and environmental problem and shortage of water resources as well as hundreds of labor jobs will be put together and solved completely, which will be our general aim . We can't delay a minute and let alone leave the problems to our future generations.
We take the agriculture as an example and from now on we should do good preparations of labour power and materials and financial capital as well as technology. From 2020 China will carry on a unprecedented and super huge project since the beginning of human history .The whole project will be done for 200 years and total investment will be 200 trillion Yuan with 1 trillion Yuan each year. 200 million of labour power will need to join in the project and 10 million mu of artificial cultivable land will be made a year. In 200 years our nation will make 2 billion mu of artificially cultivated land and adding our existing 2 billion mu of natural cultivable land（I don’t say 1.6 or 1.8 billion mu of natural land ）it will be 4 trillion mu of cultivable land .According to this calculation by 2050 we will get 300 million mu of artificial cultivable land .Producing grain 500㎏ per mu a year, newly increased grain production ability of 300 million mu of artificial cultivable land will be 150 million tons of grain . Our present grain production ability is about of 500 million tons and adding together it will be 650 million tons of grain .If the minimum per capita consumption of grain a year is 400 ㎏ which is universalized in the world, 1.5 billion of Chinese? population need to consume 600 million tons of grain. At that moment our nation will be more than self-sufficient in grain, which means that relying on one's own efforts we will solve primarily the food problem in China. By 2200 2 billion mu of artificial cultivable land will be made and our nation will reach 4 billion mu of cultivable land. Theoretically our total grain yield will reach 1.5-2.0 billion tons a year. Only by that time can I say that Chinese food problem will be solved completely.
Next, I will graft the road map of CAS onto my road map including 8 big systems and then I need to do some deleting and incorporating and making up and my road map will be completed.
