Abstract:
In order to explore the degradation performance of different degraded plastic films and their influences on soil physical and chemical properties and growth and yield of mini-watermelon in open field,‘Hongling’ watermelon was used as materials to study the degradable plastic film 1 (F1),degradable plastic film 2 (F2),degradable plastic film 3 (F3),degradable plastic film 4 (F4) and common plastic film (CK) on soil temperature,soil moisture content,mini-watermelon growth,fruit characteristics and yield.The results showed that there were no differences on the soil temperature,soil water content,main vine length,stem diameter,leaf number,whole plant dry mass,fruit transverse diameter,fruit vertical diameter,fruit index,central sugar content,edge sugar content and pericarp width of mini-watermelon in different treatments compared with CK.But,F2 showed significantly higher fruit dry mass,single fruit weight and yield in comparison with CK.At the end of the growth period,the degradation rate of F1,F2,F3 and F4 was 7.49%,25.97%,31.26% and 27.98% respectively.In conclusion,F2 was suitable for popularization and application for mini-watermelon open field cultivation in northwest Shandong Province,which could increase the temperature and keep the moisture content,promote dry matter accumulation in the fruit,increase single melon weight and yield,and had good degradation effect.
