Today I went to the country to see my uncle。 Seeing the green cabbages and the fine wheat， I couldn"t help asking how he could grow them so well。Uncle said that science of farming was important。
It included: choosing the best seeds; keeping the condition of soil good and ploughing deeply; sowing the seed and growing young plants at the correct time; changing the crops in the fields; and giving plenty of water， light and fertilizer。
