Leaf growth of wheat plants, tiller emergence and the effectiveears from tillering, the emergence and death dynamics of populational stemsand tillers, the developmental dynamics of leaf area index, the accumulationdynamics of populational dry matter, the yield and yield components underdifferent planting patterns (namely, broad casting, sparse dibbling, drilling andclose dibbling)and different planting rates(1.2×10~5 seedlings/mu and 1.8×10~5seedlings/mu) were studied. The results showed that close dibbling was able bothto promote and control...
