    摘要:

    为实现设施番茄准确有效施肥管理,以改良金棚8号番茄为试验材料,常规基质栽培番茄营养液管理方式为对照(CK),将番茄结果时期与营养液滴灌频率2因子完全交互耦合,番茄结果期划分为结果前期(第3穗果坐果~第1穗果成熟)和结果后期(第1穗果成熟~第5穗果成熟),各结果期滴灌频率均设置1、3、5次/d共3个频率(供应营养液总量相同),共10个处理,研究不同耦合处理对番茄不同层果实品质和产量的影响。利用主成分分析法、逼近理想解排序法、隶属函数分析法、灰色关联度分析法4种单一综合评价方法对番茄多层果实进行品质-产量单一算法综合评价,对通过事前一致性检验(Kendall-W)的单一综合评价结果进行模糊Borda组合评价,确定最优营养液滴灌频率方案。结果表明,耦合处理能显著增加番茄产量,不同层果实品质指标最优时,对应的耦合处理不同。4种单一综合评价方法的排序结果存在差异,Kendall-W一致性检验的协和系数为0.920,满足模糊Borda组合评价条件。主成分分析法与模糊Borda法的排序结果相关系数最高,为0.988。基于模糊Borda组合评价方法得出,结果前期1次/d、结果后期3次/d的滴灌频率可兼顾番茄获得较高产量和多层果实品质较优,为最优的营养液滴灌管理方案。本研究结果为设施番茄生产营养液科学管理提供依据。

    Abstract:

    Aiming to implement accurate and effective fertilizer management for protected cultured tomato, the tomato‘improved Jinpeng No.8’was selected as material. With the conventional substrate cultivation tomato nutrient solution management method as the control (CK), the tomato fruiting period was divided into the early fruiting stage (the third fruit of fruit set ~ the first of fruit mature) and the late fruiting stage (after the first ear of fruit mature ~ the fifth ear of fruit mature), the drip irrigation frequency in each fruiting period was set to be 1 time/d, 3 times/d and 5 times/d (the total amount of nutrient solution supplied was the same), and a total of 10 treatments. In order to study the effect of different treatments on the different layers fruit quality and yield of tomato, the effects of different treatment on quality and yield were investigated. Four single comprehensive evaluation methods, including principal component analysis, TOPSIS, membership function analysis and grey correlation analysis, were used to comprehensively evaluate the quality-yield of tomato multi-layer fruits. The single comprehensive evaluation result of the consistency test (Kendall-W) was used for fuzzy Borda combined evaluation to determine the optimal nutrient solution drip irrigation plan. The results showed that coupling treatment can significantly increase tomato yield. When the quality indexes of different layers of fruit were the best,the corresponding coupling treatments were different. There were differences in the ranking results of the four single comprehensive evaluation methods. The Kendall-W consistency test had a concordance coefficient of 0.920, which satisfied the combined evaluation conditions. The principal component analysis method and the fuzzy Borda method had the highest correlation coefficient (0.988). The best drip irrigation frequency was 1 time/d in the early fruiting stage; 3 times/d in the late fruiting stage based on the fuzzy Borda method, which can achieve higher yields of tomatoes and multi-layer fruits with high quality. The research result can provide the basis for scientific management of nutrient solution produced by facility tomato.
