Abstract:

【Objective】 This study aims to explore the optimal water and fertilizer application scheme suitable for sand cultivated tomato in southern Xinjiang and provide a reasonable theoretical basis for sand cultivated tomato production in this region.【Methods】 The test set four factors: irrigation water, nitrogen, phosphorus and potassium, five levels in each factor; By using four binary universal rotation combinations, a total of 20 treatment combinations, each repeated 3 times to determine the tomato leaf chlorophyll content difference and synthetic day characteristics, and finally, the principal component analysis was carried out for comprehensive evaluation.【Results】 The ranking of the treatments was g9 > g3 > g7 > g11 >g5 >g2> g18 >g12 >g1> g6> g16>g4 >g14> g20>g10> g19> g17> g13> g15>g8.Each index in g9 treatment was well.【Conclusion】 In the process of tomato sand cultivation in southern Xinjiang, g9 treatment (the irrigation level : 310mm/hm2, the amount of nitrogen: 570 kg/hm2, the amount of phosphorus: 438 kg/hm2, the amount of potassium: 738 kg/hm2) can effectively promote the growth and development of tomato plants.

摘要:

【目的】 研究适宜新疆南疆沙培番茄的最优水肥施用方案,为南疆沙培番茄生产提供合理的理论依据。【方法】 设置灌溉水量、施氮量、施磷量和施钾量4个因素,每个因素设定5个水平,采用四元二次通用旋转组合设计(二分之一),共20个处理,每个处理3次重复,测定各处理组合番茄叶片叶绿素含量差异以及光合日变化特征,运用主成分分析法进行综合评价。【结果】 各处理组番茄叶片的净光合速率。综合评价得到水肥耦合下各处理的优劣排序为g9>g3>g7>g11>g5>g2>g18>g12>g1>g6>g16>g4>g14>g20>g10>g19>g17>g13>g15>g8,g9处理各项指标表现较好。【结论】 在新疆南疆番茄黄沙栽培过程中g9处理(即灌水水平为310 mm/hm2,施氮量为570 kg/hm2,施磷量为438 kg/hm2,施钾量为738 kg/hm2),可有效促进番茄植株的生长发育。
