Baesd on problems of high-protein-wheat production,the importance of deep tillage and intensive cultivation,water controlling and nitrogenous fertilizer postponing in high gluten wheat cultivation were illustrated in this paper,and the main technologies of every growth period of high-protein-wheat were also illustrated.

Effects of mounted parameters on tillage depth of the driven powered disk plow;

The rotary tiller may have many advantages such as small size, high driving force, easily adjustable tillage depth (the maximum tillage depth is 20 cm),Vtype plough and shovel.

Dynamic identification of the automatic monitoring and controlling ploughing depth system of trac-tor;

ANSYS/LS-DYNA software is used to carry out the turning dynamics simulation of sugarcane deep tilling plough.

This Thesis through the experiment of subsoiling and studying the maize earthnut and millet in 863 testing farmland Matiying village Fuxin county Liaoning province,the result indicates: The influence of subsoiling to the main growth index of different crop is different,In proper order is :maize millet and peanut.

2 subsoiler in 863 testing farmland Matiying village Fuxin county Liaoning province, contracting and studying containing water of soil of the corn ﹑earthnut and millet, which is subsoiled or nonsubsoiled, illuminating the influence of subsoiling to containing water of soil, educing that the subsliling can popularized in agricultural production .
