求翻译：结果表明，不同秸秆覆盖量对小麦生长发育和产量的影响不同。本实验中，由于覆盖量都比较大，在小麦出苗时，受到的地面阻力比较大且见不着阳光，因此小麦出苗率不断降低是什么意思？

The results showed that straw mulch on the growth and yield of wheat. This experiment, the coverage amount is relatively large, when wheat emergence by ground resistance is relatively large and faceless to the sun, so the wheat seedling emergence continue to lower

Results indicate that different straw, amount of coverage for the wheat growth and yield of different effects. In this lab, the amount of coverage, the wheat seedlings in the ground, when resistance is larger and is not in the sun, therefore the wheat seedlings continue to reduce rates

The result indicated that, the different straw stalk cover quantity is different to the wheat growth growth and the output influence.In this experiment, because the cover quantity quite is all big, emerges when the wheat, receives the ground drag quite is big also cannot see the sunlight, therefore

Results show that different straw mulching on growth and development and yield of different wheat. In this experiment, because the cover is large, at the time of emergence of wheat, ground resistance comparison and see the Sun, therefore falling wheat seeding rate
