对在不同覆盖物覆盖下玉米生长发育和土壤性状的变化情况进行了试验研究。结果表明：麦秸覆盖玉米的经济产量和生物产量与不覆盖玉米差异不显著；生物覆盖与不覆盖相比，虽然玉米经济产量显著减产，但总经济产量下降幅度不大，生物产量则有明显提高。不同覆盖物对玉米的生长发育、杂草发生、土壤温度、土壤水分和土壤有机质含量等方面均有不同的影响。据试验结果建议：夏玉米生产上推广麦秸覆盖免中耕有利于节约能源、劳力，提高劳动生产率和培肥地力。在水利条件好而地力差的地区，推广生物覆盖，有利于农牧结合解决饲草不足的问题。
The changes of corn growth and development and soil properties under different coverings were studied. The results showed that there was no significant difference between the economic yield and the biomass yield of maize covered with maize and that of uncoated maize. Compared with the non-covered maize, the economic output of maize significantly decreased but the total economic output decreased less and the biological yield increased significantly . Different coverings have different effects on the growth and development of corn, weed occurrence, soil temperature, soil moisture and soil organic matter content. According to the results of the experiment, it is suggested that the promotion of summer maize production to promote the wheat-free cultivation without tillage will save energy and labor, improve labor productivity and fertility. In areas with good water conditions and poor land fertility, the promotion of biological coverage is conducive to the integration of agriculture and animal husbandry to solve the problem of forage shortage.
