    摘要:

    為實現(xiàn)設(shè)施番茄準確有效施肥管理,,以改良金棚8號番茄為試驗材料,常規(guī)基質(zhì)栽培番茄營養(yǎng)液管理方式為對照(CK),,將番茄結(jié)果時期與營養(yǎng)液滴灌頻率2因子完全交互耦合,,番茄結(jié)果期劃分為結(jié)果前期(第3穗果坐果~第1穗果成熟)和結(jié)果后期(第1穗果成熟~第5穗果成熟),各結(jié)果期滴灌頻率均設(shè)置1,、3,、5次/d共3個頻率(供應(yīng)營養(yǎng)液總量相同),共10個處理,,研究不同耦合處理對番茄不同層果實品質(zhì)和產(chǎn)量的影響,。利用主成分分析法、逼近理想解排序法,、隸屬函數(shù)分析法,、灰色關(guān)聯(lián)度分析法4種單一綜合評價方法對番茄多層果實進行品質(zhì)-產(chǎn)量單一算法綜合評價,對通過事前一致性檢驗(Kendall-W)的單一綜合評價結(jié)果進行模糊Borda組合評價,,確定最優(yōu)營養(yǎng)液滴灌頻率方案,。結(jié)果表明,耦合處理能顯著增加番茄產(chǎn)量,,不同層果實品質(zhì)指標最優(yōu)時,,對應(yīng)的耦合處理不同。4種單一綜合評價方法的排序結(jié)果存在差異,,Kendall-W一致性檢驗的協(xié)和系數(shù)為0.920,,滿足模糊Borda組合評價條件,。主成分分析法與模糊Borda法的排序結(jié)果相關(guān)系數(shù)最高,,為0.988,。基于模糊Borda組合評價方法得出,,結(jié)果前期1次/d,、結(jié)果后期3次/d的滴灌頻率可兼顧番茄獲得較高產(chǎn)量和多層果實品質(zhì)較優(yōu),為最優(yōu)的營養(yǎng)液滴灌管理方案,。本研究結(jié)果為設(shè)施番茄生產(chǎn)營養(yǎng)液科學(xué)管理提供依據(jù),。

    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.
