地埋式秸秆反应堆技术对土壤呼吸及番茄植株生长的影响

Effects of Buried Straw Reactor Technology on Soil Respiration and the Growth of Tomato Plants

以番茄为试验材料,研究不同秸秆反应堆处理对温室大棚土壤温度、二氧化碳通量以及番茄植株生长、产量和品质的影响。结果表明,行内秸秆反应堆较行间秸秆反应堆处理能够增加番茄大棚土壤温度3.1~4.5℃。秸秆反应堆处理技术可以有效解决晴天上午和下午日光温室内CO_(2)亏缺问题,提高不同生育阶段番茄株高、茎粗和叶绿素含量、叶片光合特性,提高果实维生素C含量、游离氨基酸含量、可溶性蛋白含量、可溶性糖含量、番茄红素含量,降低硝酸盐含量;与CK相比,行内反应堆处理番茄产量增加5.18%。秸秆反应堆提高了土壤温度,促进了植株生长,能够促进番茄提早15~20 d转色,促使番茄提早上市,其中BR处理效果最好,BR-S和BR-D处理次之。

Using tomato as experimental materials,the effects of different straw reactor treatments on soil temperature,carbon dioxide flux and tomato plant growth,yield and quality were studied.The results showed that compared with the inter⁃row straw reactor treatment,the in⁃row straw reactor treatment could increase the soil temperature of tomato greenhouse by 3.1-4.5℃.The treatment technology of the in⁃row straw re⁃actor could effectively solve the CO2 deficit in the solar greenhouse in the morning and afternoon on sunny days,significantly improve the plant height,stem diameter,chlorophyll content,leaf photosynthetic characteristics,and vitamin C content,free amino acids,soluble protein,soluble sugar and lycopene content of tomato at different growth stages,and reduce nitrate content.The yield of tomato in row reactor increased by 518%.Straw reactor increased soil temperature and promoted plant growth,which could promote the color transformation of tomatoes 15-20 days earlier and promote the early market of tomatoes.BR treatment had the best effect,followed by BR-S and BR-D.
