摘要
以"红灵"小西瓜为试材,研究了覆盖降解膜1(F1)、降解膜2(F2)、降解膜3(F3)、降解膜4(F4)及普通地膜(CK)对土壤温度、土壤含水量、小西瓜生长、果实性状及产量的影响,以期探究不同降解地膜的降解性能及对土壤理化性质和露地小西瓜生长产量的影响。结果表明:不同地膜处理的土壤温度、土壤含水量、小西瓜主蔓长、茎粗、叶片数、全株干质量、果实横径、果实纵径、果形指数、中心糖、边糖及果皮厚度与CK差异不显著,但F2处理的果实干质量、单瓜质量和单位面积产量显著高于CK。生育期结束,F1、F2、F3、F4膜的降解强度分别为7.49%、25.97%、31.26%、27.98%。综上,F2能增温保墒,促进果实中干物质积累,增加单瓜质量和产量,降解效果好,适合在鲁西北地区露地小西瓜生产中推广应用。
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.
