生物有机肥在设施番茄上的应用效果研究

为探索生物有机肥的应用效果，通过田间试验，设置了4个处理，分别为常规施肥（CK:鸡粪有机肥800 kg·667m-2）、生物有机肥1（T1:用量为150 kg· 667m-2）、生物有机肥2（T2:用量为300 kg· 667m-2）、生物有机肥3（T3:用量为450 kg· 667m-2），研究了不同生物有机肥用量对设施番茄生长发育、产量、品质和经济效益的影响。研究结果表明，随着生物有机肥用量的增加，番茄的单株果数、单果重、产量、Vc含量和可溶糖含量呈现增加的趋势。与CK相比，T3处理的番茄产量显著提高了169.1 kg· 667m-2，增幅达8.75%。与CK相比，T2和T3处理的番茄Vc含量分别显著提高13.3%和15.4%，T1、T2和T3处理的番茄可溶糖含量显著增加10.7%、13.9%和15.9%。T3处理的番茄纯效益较CK处理显著增加8.89%。综上所述，在试验地区域番茄生产重生物有机肥的推荐用量为300~450 kg· 667m-2。

Study on the application effect of bio-organic fertilizer on facility tomato

In order to explore the application effect of bio-organic fertilizer, four treatments were set up through field experiments, namely conventional fertilization (CK: chicken manure organic fertilizer 800 kg · 667m-2 ), bio-organic fertilizer 1 ( T1: 150 kg · 667m-2 ), bio-organic fertilizer 2 ( T2: 300 kg · 667m-2 ), bio-organic fertilizer 3 ( T3: 450 kg · 667m-2 ). The effects of different bio-organic fertilizer application rates on the growth, yield, quality and economic benefits of greenhouse tomato were studied. The results showed that with the increase of the amount of bio-organic fertilizer, the fruit number per plant, fruit weight, yield, Vc content and soluble sugar content of tomato showed an increasing trend. Compared with CK, the yield of tomato treated with T3 increased by 169.1 kg · 667m-2, an increase of 8.75 %. Compared with CK, the Vc content of tomato treated with T2 and T3 increased by 13.3 % and 15.4 %, respectively, and the soluble sugar content of tomato treated with T1, T2 and T3 increased by 10.7 %, 13.9 % and 15.9 %, respectively. The pure benefit of tomato in T3 treatment was significantly increased by 8.89 % compared with CK treatment. In summary, the recommended amount of heavy bio-organic fertilizer for tomato production in the experimental area is 300 ~ 450 kg · 667m-2
