In terms of the problem with the cotton production in Xinjiang, under the ensuring of high yield, proper decreasing invert of the substance, machinery and labor force could simply cultivate, save cost and increase profiets.

The light and simple cultivation technique with simple cultivation management process and lower work intensity based on the core of the natural no-tillage transplanting and no-tillage directive sowing technique,accords with the objective demands because the rural labor force is shifting from rural to city.

With japonica rice Yangfujing 8 as material,dry matter production,yield formation and the related physiological traits of rice under simplified cultivations(direct seeding,mechanical transplanting and parachute transplanting)with wheat residue return and wheat residue removal were investigated.
