Some characteristics of rice cultivated in aerobic soil mulched with semi-decomposed straw and plastic film and without any mulch were compared under field conditions.

Effects of straw mulch on the growth of maize under insufficient irrigation;

Requirements of water and nitrogenous fertilizer to increase winter wheat yield under straw mulch;

Simulation study on influence of straw mulch on soil moisture and heat of summer corn farmland;

Straw cover not only has the obvious effect of water storage and moisture preservation,but also can improve the physical and chemical properties of soil,fertilization of arable land fertility,and reduce soil erosion,which is a measure that has very significant effect in dry farming production technology.

Therefore,the controlled traffic tillage with straw cover was adopted based on the ridge culture techniques,by changing flood irrigation to furrow irrigation to study the effect of soil water under controlled traffic tillage irrigation.

The influence of permanent no-tillage with straw cover in long term on the change of soil total organic nitrogen had been studied in Dingxi county,one of the typical semi-arid areas in Gansu Province.

Effects of straw mulching quantities on the growth of root and canopy of maize under different water condition;

Effect of straw mulching on soil temperature before the greening stage of winter wheat in dryland;

Study on the soil evaporation of winter wheat under different straw mulching;

Soil critical moisture for seeding under straw mulching was studied.

Soil critical moisture for seeding under mulching was studied by indoor and outdoor experiments.

Effect of Straw Mulching on Water Physiological Parameters of Pear;
