不同绿色生态技术模式对番茄生长的影响

Effects of different green ecological technology models on tomato growth

为更好地进行生态农业技术应用,探索不同绿色生态技术模式下番茄生长情况,筛选适宜于番茄种植的最佳模式。设置4种种植技术模式:“三零”种植技术(T1);行下内置式秸秆生物反应堆技术(T2);蚯蚓生物垄侧套种套养技术(T3);蚯蚓生物垄上套种套养技术(T4);以常规栽培作为对照(CK),比较不同蔬菜绿色生态技术模式对番茄生长、品质及产量的影响。结果表明,T1番茄总产量较CK显著提高24.86%;果实总糖含量与CK无显著差异,土壤全磷含量与T3无显著差异,但显著高于其他处理,且糖酸比、维生素C含量、土壤有机质含量及有效磷含量均显著高于其他处理,其中,糖酸比较CK、T2、T3分别显著提高12.52%、13.68%、17.12%;维生素C含量分别较CK、T2、T3、T4显著提高7.97%、65.56%、59.53%、29.57%;土壤有机质含量较CK、T2、T3、T4分别显著提高4.59%、17.14%、19.19%、22.02%;其土壤重金属砷、镉含量最低。综合判定,T1种植效果最佳,可以作为设施番茄最佳种植模式在生产中推广应用。

In order to make better application of eco-agriculture technology,and select the best planting mode suitable for tomato cultivation,four planting technology modes were set up:"three-zero"planting technology(T1),inline straw bioreactor technology(T2),interplanting and interbreeding technology(T3),interplanting and interbreeding technology of earthworm on ridge(T4),using conventional cultivation as control(CK).The effects of different green ecological technology models on tomato growth,quality and yield were compared.The results showed that the total yield of T1 was 24.86%higher than that of CK.The total sugar content,sugar-acid ratio,vitamin C content,soil organic matter,total phosphorus and available phosphorus content were significantly higher than those of other treatments.The sugar-acid ratio of T1 was 12.52%,13.68%and 17.12%higher than that of CK,T2 and T3,respectively.Vitamin C content of T1 was significantly higher than CK,T2,T3 and T4 by 7.97%,65.56%,59.53%and 29.57%,respectively.The content of soil organic matter was 4.59%,17.14%,19.19%and 22.02%higher than CK,T2,T3 and T4,respectively.The content of heavy metals arsenic and cadmium in soil decreased significantly.According to the comprehensive judgment,T1 has the best planting effect and can be used as the best planting mode of facility tomato for promotion and application in production.
