Different Fully Biodegradable Plastic Film Mulching on the Growth and Yield of Tomato in Solar Greenhouses
摘要
Abstract
This study uses'Saint Laurent 3690'tomatoes as the test material,10 μm thick black polyethylene(PE)film as the control(CK),while treatments T1,T2,and T3 are 8 μm,10 μm,and 12 μm thick black PBAT/PLA fully biodegradable plastic films,respectively.By analyzing the effects of different film mulching on tomato growth and yield,this study aims to identify the most suitable fully biodegradable plastic film for tomato cultivation in solar greenhouses.The results show that 60 days after planting,T2 exhibits the highest plant height,exceeding CK,T1,and T3 by 1.7%,4.3%,and 3.3%,respectively.No significant differences are observed in the dry or fresh weights of tomato organs across treatments.At 120 days after planting,the stem diameter of T3 tomatoes is the highest,which is 0.8%higher than CK.The fresh weight of T3 tomatoes is also the highest,which is 2.0%higher than CK.The root vigor of T1 is the lowest,significantly lower than that of the other treatments,being 5.5%,6.2%,and 3.3%lower than CK,T2,and T3,respectively.The contents of soluble sugar,lycopene,vitamin C,and soluble solids in the 1st,3rd,and 5th cluster are highest in T3,with no significant difference among the treatments.Tomato yield is also highest in T3(3.3%higher than CK)and T2(2.2%higher than CK),with no significant difference among the treatments.Soil burial tests reveal that all three biodegradable films degrade almost completely within 30 days.Considering both benefits and costs,the 10 μm thick black PBAT/PLA fully biodegradable plastic film is recommended for tomato production in solar greenhouses.关键词
