无纺布限根栽培对西瓜根域温度、植株生长和果实品质的影响
Root zone temperature,plant growth and fruit quality of watermelon affected by nonwoven-fabric-root-restriction-cultivation
摘要
Abstract
Effect of nonwoven root restriction method on root temperature, plant growth and fruit quality of ‘Xiangxiu' watermelon were investigated.Results suggested that this method restriction dramatically increased temperature of the roots around 5- 25 cm below the soil surface,with a mean root temperature increase of 2.31 ℃.The stem length, leaf number and relative leaf area of the early stage of plant growth increased by comparing to the control group.Root of watermelon was mainly restricted in cultivated layer,or 0- 28 cm below the soil surface.The main root was very short and has a high root density and root activity.Root restriction also improved fruit quality dramatically,for example,the SSC,juice yield, Vc content and flavonoid content were improved under this condition.The significant difference was observed between RR and CK (P＜0.05 or P＜0.01).However, there is no effect on fruit fresh weight, TA and lycopene content.关键词
