摘要
[目的]针对使用多年的设施栽培(温室和大棚)内土壤发生不同程度的次生盐渍化等土壤性质恶化问题,以田园土、粉碎的玉米秸秆和干鸡粪作为试验的主要材料,分析不同配比堆制人工营养土对温室番茄(Lycopersicon esculentum)生长发育的影响。[方法]试验共设4个处理:T1,玉米秸秆∶园土=3∶1;T2,玉米秸秆∶园土=2∶1;T3,玉米秸秆∶园土=1∶1;CK,100%园土作对照。其中各处理及对照均加鸡粪20 kg/m3,混合均匀后,加水使肥堆的含水率保持在70%左右。[结果]T1处理(秸秆比例最高)的番茄糖酸比最高为7.15±0.02,T1、T2、T3处理分别比不加秸秆的CK高出72.7%、21.2%、30.2%。番茄果实的维生素C含量T1处理最高,T1、T2处理分别比CK高出45.0%和22.1%。T1、T2和T3处理的产量分别比CK高出了32.7%、20.0%和12.8%。[结论]建议采用T1处理(干玉米秸秆∶园土=3∶1+干鸡粪20 kg/m3)作为设施栽培内番茄人工营养土的最佳配比。
[Objective] According to the soil degradation problems in protected cultivations(greenhouse),such as different degrees of secondary salinization,the garden soil,crushed corn straw and dry chicken manure was chose as the major materials and the effects of different proportion component artificial nutrition soil on tomato growth and development were analyzed.[Method] Four treatments was designed,the ration of corn straw to garden soil was 3∶ 1,2∶ 1 and 1∶ 1 resp.,marked as T1,T2 and T3 resp.,100% garden soil was taken as control(CK).Thereinto,three treatments and CK was all added into 20 kg/m3,then added into water after mixing well to keep up the water content about 70%.[Result] The results showed that T1 treatment(the highest straw proportion) of sugar acid ratio was the highest by 7.15± 0.02,T1,T2,T3 treatment's sugar acid ration were higher 72.7%,21.2%,30.2% than that of CK resp..Tomato fruit content of vitamin C of treatment T1 was the highest,T1,T2 treatment's vitamin C content were higher 45.0% and 22.1% than that of CK resp..Yield of T1,T2 and T3 treatment were higher 32.7%,20.0% and 12.8% than that of CK resp..[Conclusion] T1 treatment(dry corn straw: garden soil = 3∶ 1 plus dry chicken manure 20 kg/m3) is the best ratio of artificial nutrition soil as facility cultivation of Tomato.
