摘要:

考察保水剂对枸杞根际土壤环境及其生长过程中的作用,为保水剂在枸杞种植方面的应用提供理论参考。以3年生红枸杞为研究对象,运用环状沟施法将保水剂与复合肥的混合物施于枸杞根部,探究其对根际土壤特性、植株生长状况、果实品质以及产量的影响。研究结果显示:(1)施加50 g保水剂的处理使土壤容重降低31.13%,总孔隙度提高25.82%,田间持水量提升至原来的1.49倍,水稳性团聚体含量增加66.45%,团聚体破坏率降低67.50%。(2)随着保水剂用量的增加,7月和9月枸杞根际土壤中速效氮、磷、钾的含量呈现出先快速上升后缓慢上升的趋势,而有机质含量的变化并不显著。(3)保水剂能够显著促进枸杞的生长发育,枸杞的株高、冠幅、茎粗以及叶绿素含量均随着保水剂用量的增加而提高。(4)7月,施加50 g保水剂的处理使果实的可溶性固形物、总糖和维生素C含量达到峰值,相较于对照分别提高8.40%、42.96%和76.27%;施加60 g保水剂的处理使果实的百粒重和果形指数达到最大,相较于对照增幅分别达到47.82%和30.26%。(5)保水剂的施用具有显著的增产效果,施加50 g保水剂的处理产量相较于对照提升31.70%。综上所述,保水剂处理能够改善枸杞根际土壤的结构和特性,增强土壤的保肥能力,促进植株的生长发育,改善果实品质,进而提高产量。

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.
