Abstract
In order to make full use of plastic film and reduce the pollution,a study on re-used plastic film in Hetao area of Inner Mongolia was conducted during 2010—2011.There were three treatments including mulching and on-lines planting(JS),mulching and under lines planting(JJ) and bare field planting(W),the effects of re-used plastic film on soil temperature and sunflower yield under no-tillage were investigated.The results showed that: the temperature under JJ and JS treatments in 0—50 cm soil layer were both higher than that of W in the whole growth period with significant difference(p0.05) in sowing stage and seedling stage.In 0—10 cm soil layer,the re-used plastic film could increase soil temperature effectively and made the effective accumulated temperature that sunflower was needed reach in advance,and then promoted the emergence and shorten growth period.In the whole growth period,the total effective accumulated temperature(≥10℃) of JJ and JS were 176.08℃ and 166.47℃ higher than that of W in 5 cm soil layer,respectively,the growth period had been shortened for 5~7 days,and the differences were significant.The daily change of soil temperature showed a single peak curve in 0—20 cm soil layer,and with the deepening of soil depth and the advancement of growth period,the time of the soil temperature peak had been delayed and the time of re-used plastic film was behind the bare field.The grain yield in 2010 and 2011 of JJ was 1.34% and 0.88% more than that of JS,12.92% and 17.82% more than that of W.This indicated that the old plastic film also had re-used potential,and the effects of mulching and under lines planting were better.
