摘要
为了减少白色污染对土壤环境的影响,研究了不同用量的液态地膜对玉米生育期土壤墒情、地温、出苗时间、株高、杂草抑制率、产量的影响,并将其与塑料地膜和裸地进行对照,结果表明:不同用量的液态地膜较裸地在提高地温、保持土壤墒情、抑制杂草方面均有较明显的作用,其中,液态地膜用量225kg/hm2的处理杂草抑制率最高,为65.7%;液态地膜对玉米有明显的增产作用,其中,用量300kg/hm2的处理增产率达19.7%。
In order to reduce the impact o; white pollution on environment, the effect of different amounts of liquid membrane on soil moisture, ground temperature below 5 cm, emergence time, plant height, weed suppression rate and yield of corn was studied in the growing season, taking the plastic mulch and bare ground as CK. The results showed that the different amounts of liquid membrane were all better than bare land in increasing the soil temperature, maintaining the soil moisture,and suppressing the field weeds. Two hundred and twenty five kg/ha of liquid membrane was the best dosage for inhibiting the weeds,the suppression rate up to 65.7%. The liquid membrane could increase the corn yield obviously,and the best dosage was 300 kg/ha,which in- creased the yield by 19.7%.
