It seeds area and total yield are big in our country.This study combined Hubei province item of the project of country important food foisori science and technology. It considered the difference of climate character、 cultivate system and plant habit in the southeast of Hubei、 in the middle of Hubei、 in the northwest of Hubei and in the Jianghan plain four rice plant areas. It had formed " double season rice three ripe high yield in the southeast of Hubei mode "、" sparse、 manipulative、 weight middle season rice high yield in the middle of Hubei mode"、" zero till light-duty high yield plant in the Jinghan plain mode" and " cover with ground film wet in all process in the northwest of Hubei plant mode" four adaptive plant modes base on present plant modes.
