摘要/Abstract

摘要： 通过番茄（Solanum lycopersicum L.）盆栽试验研究了市售肥料（有机肥和化学肥料）和两种不同高分子缓释肥对土壤和植株的影响。经物理混合和化学反应将含有营养元素（氮、磷、钾）的高分子缓释肥与羟乙基纤维素吸水树脂制备出两种不同的高分子缓释肥,按照相同的施肥量,将市售肥料和两种高分子缓释肥分别施入番茄盆栽中,观测番茄植株生长情况（植株高度、叶片叶绿素含量、植株干物质量、番茄果实数和单果质量）、番茄果实品质（番茄红素、维生素C、有机酸和可溶性糖含量）及土壤理化性质（水分、铵态氮、硝态氮含量及过氧化氢酶和脲酶活性）的变化。结果表明,羟乙基纤维素高分子缓释肥施入土壤中后,土壤养分含量和酶活性明显增加,两种高分子缓释肥土壤铵态氮和硝态氮含量比市售肥料分别增加了16.61%、48.06%和21.61%、84.64%;与市售肥料相比,两种高分子缓释肥对番茄叶片的叶绿素含量和果实品质也有明显的改善作用,而且还提高了番茄果实数,分别增加了40.74%和33.33%。由此可知,羟乙基纤维素高分子缓释肥可广泛应用于农作物生产中。

Abstract: The effects of commercially available fertilizers （organic and chemical fertilizers） and two different polymer slow release fertilizers on soil and plants of tomato（Solanum lycopersicum L.） were studied by pot experiment. Two different polymer slow release fertilizers were prepared by physical mixing and chemical reaction of NPK-containing polymer slow release fertilizer and hydroxyethyl cellulose water-absorbing resin. According to the same fertilizer application amount, commercially available fertilizers and two kinds of polymer slow-release fertilizers were applied to tomato pots respectively to observe the growth of tomato plants（plant height, leaf chlorophyll content, plant dry weight, tomato fruit number and tomato fruit weight）, tomato fruit properties（the content of lycopene, vitamins C, organic acids and soluble sugars） and soil physical and chemical properties（moisture content, ammonium nitrogen content, nitrate nitrogen content, catalase and urease activity）. The results showed that the soil nutrient content and enzyme activity increased compared with the commercially available fertilizer control soil, and the ammonium nitrogen and nitrate nitrogen content increased by 16.61%, 48.06%, and 21.61%, 84.64%, respectively. Two kinds of polymer slow release fertilizers significantly improved the chlorophyll content and tomato fruit quality of tomato leaves, and also increased the number of tomato fruits, increasing by 40.74% and 33.33%. Consequently, hydroxyethyl cellulose polymer slow release fertilizer can be widely used in agricultural production.
