试验表明，双覆条播与常规露地条播相比，当季增产率为１６．４８ ％ ，潜在增产率为１１ ．５８ ％ ，理论增产率为２８ ．０６％ ，而且增强了小麦根系生长，地膜还可被下茬作物再利用。
Tests show that compared with the conventional open-air sowing, the double-coated sowing season increased the yield by 16.48% and the potential yield increased by 11%. 58%, the theoretical yield of 28. 06%, but also enhance the root growth of wheat, plastic film can be reused by the next crop.
