%X The studies showed that under no-tillage plus inter-planting rice and wheat, the height of rice stubble remained on the field significantly affected light transmission rate, with an optimal height of 20-30 cm. No-tillage and straw-remaining decreased soil temperature at noon in sunny days, but slightly increased it in the morning and evening, led to a less diurnal difference of soil temperature. The average diurnal soil temperature under no-tillage was higher in cloudy but lower in sunny days. Under no-tillage and straw-remaining, both the bulk density and the penetration resistance of topsoil increased, but no apparent adverse effect of them was observed on wheat growth. Under no-tillage, soil water content was higher under drought condition, and soil permeability after irrigation was better, which was propitious to the wheat growth. Straw-remaining significantly inhibited weeds, but led to the decrease of basic seedlings and enhanced the damage of freezing. Under no-tillage plus inter-planting, the individuals of effective ears decreased, while the kilo-grain weight increased. The grain yield was slightly but not significantly low under no-tillage plus inter-planting.
