Effect of Superabsorbent Polymer on Rhizosphere Soil Characteristics,Growth and Fruit Quality of Lycium chinensis
摘要
Abstract
This experiment aimed to investigate the effect of superabsorbent polymer on rhizosphere soil environment and growth process of Lycium chinensis,which provided theoretical reference and scientific basis for the application of superabsorbent polymer in L.chinensis planting.3-year-old L.chinensis was used as experimental object,the mixtures of superabsorbent polymer and compound fertilizer were applied to the root of L.chinensis by the method of ring ditch,and the effects of soil characteristics,plant growth,fruit quality and yield were studied.The results indicated that:(1)compared with the control,the application of 50 g superabsorbent polymer reduced soil bulk density by 31.13%,increased total porosity by 25.82%,increased field water capacity by 1.49 times,increased water stable aggregate content by 66.45%,and reduced agglomerate destruction rate by 67.50%.(2)The determination results of July and September showed that with the increasing of superabsorbent polymer application content,the content of available nitrogen,phosphorus and potassium in the rhizosphere soil of L.chinensis increased rapidly and then increased slowly,while the content of organic matter increased first and then decreased,but the change was not significant.(3)The growth and development of L.chinensis were significantly promoted by the application of superabsorbent polymer.The plant height,crown width,stem diameter and chlorophyll content were increased with the increase of superabsorbent polymer.(4)In July,the content of soluble solids,total sugar and Vc of the fruits reached the maximum when L.chinensis plants were treated with the 50 g superabsorbent polymer,and these quality index increased by 8.40%,42.96%and 76.27%respectively compared with the control.And with 60 g superabsorbent polymer treatments,the hundred grain weight and shape index of the fruits reached the maximum,increased by 47.82%and 30.26%respectively compared with the control.(5)The yield of L.chinensis fruits were significantly increased by the application of superabsorbent polymer.After 50 g superabsorbent polymer treatments,the yield of L.chinensis fruits was increased by 31.70%.With the superabsorbent polymer treatments on L.chinensis,the structure and characteristics of rhizosphere soil were improved,the keeping fertilizer abilities of rhizosphere soil were enhanced,the growth and development of plants were promoted,the qualities of fruit were improved,and the yield of fruit was increased.关键词
