The study looked at how different amounts of straw covering affected soil moisture, temperature, and the growth of winter wheat. They tested four amounts of straw mulching: none, 0.3 kg/m2, 0.6 kg/m2, and 0.9 kg/m2. The results showed that using 0.6 kg/m2 of straw mulching helped retain water, kept the soil warmer, and led to the highest wheat yield. This means that using 0.6 kg/m2 of straw mulching is the best for growing winter wheat.
