- 摘要:
- 为了减少农业白色污染,引进了几种降解地膜,进行了可降解地膜、普通地膜和露地栽培玉米的对比试验,探讨可降解地膜的降解性能及对土壤水分、温度和玉米生长发育的影响。结果表明:降解地膜有较好的增温保墒作用,利于玉米生长,可缩短生育期,有助增产,其中9号地膜比普通地膜增产7.1%,比露地对照增产28.4%。可降解地膜在功能上可替代普通地膜,其中12号地膜和10号地膜的降解效果最好,到翌年整地前地膜降解率分别达到13.07%和39.38%。
- Abstract:
- In order to reduce the white pollution of agriculture,the introduction of the several degradable mulch film,through the contrast test of degradable mulching film,plastic film mulching and open field cultivation of maize,the performance degradation of degradable mulch film and on soil moisture,temperature and maize growth and development were investigated.The results showed that degradable mulching film had better additional water and increased soil temperature,conducive to the growth of maize,and it could shorten the growth period,increase yield; The 9 film increased by 7.1% than ordinary film,and increased by 28.4% than open field cultivation;degradable mulch film in function could replace the ordinary plastic film,which film 12 and 10 film degradation effect best,until next preparation before the film’s degradation rate reached 13.07% and 39.38%respectively.
