滴灌对茶园土壤养分的影响初探

摘要

本论文旨在研究贵州省开阳县茶园种植区的土壤N、P、K和有机质在滴灌

灌溉方式下的变化规律，通过走访调查和在典型种植区的滴灌实验得出的相关数据，再利用spss软件分析中的T检验和单样本非参数检验的曼－惠特尼U检验两中数据分析方法进行数据的处理分析，以此研究滴灌对茶园土壤养分的影响。结果表明，土壤中碱解氮含量的明显受到滴灌的影响，表现为滴灌使得耕层土壤中碱解氮含量明显减少；滴灌灌溉使得耕层中的表层土壤全磷、全氮含量明显减少，根层中的含量差异不大；而耕层土壤中速效磷、速效钾和有机质在空白与滴灌作用的差异不显著。在空白和滴灌在垂直方向上的显著性差异得出，随深度的增加滴灌地块和空白地块的全氮、碱解氮、全磷、速效磷、速效钾和有机质的含量均明显减少；滴灌会使得表层与根层土壤中的全氮、速效磷、速效钾和有机质差异率减少，其结果表现为，滴灌表层与空白表层相比有所减少，而根层有所增加；而滴灌对土壤中碱解氮和全磷在垂直方向的没有明显的影响。

The influence of drip irrigation in tea garden soil

nutrients

Abstract

This paper aims to study in guizhou kaiyang tea garden area of soil N, P, K and

organic matter, the change rule of under drip irrigation methods through visiting survey and in the typical area of drip irrigation experiment data, using SPSS software analysis of T in the inspection and the mann - Whitney U two data analysis methods to analyze data processing, in order to study the effect of drip irrigation in tea garden soil nutrients. The results showed that the concentrations of alkali in the soil solution of influenced by drip irrigation, characterized by drip irrigation made arable layer soil alkali-hydrolysable nitrogen content decreased significantly; Drip irrigation makes the top layer of the surface soil total phosphorus, total nitrogen content decreased significantly, the concentration difference in root layer; In the top layer of soil available phosphorus, available potassium and organic matter in the blank with no significant difference in drip irrigation effect. In the blank and the significant difference of drip irrigation in the vertical direction, with the increase of the depth of the drip irrigation plot and blank plot of total nitrogen, alkali solution nitrogen, total phosphorus, available phosphorus and available potassium and organic matter content were significantly reduced; Drip irrigation makes the soil total nitrogen, available phosphorus and available potassium and organic matter the difference between surface and root layer rate decreases, the result is, drip irrigation surface than the blank surface decreases, drip irrigation root layer than blank root increased; And alkaline hydrolysis in drip irrigation on soil nitrogen and total phosphorus in the vertical direction have no obvious impacts.
