Effects of Buried Straw Reactor Technology on Soil Respiration and the Growth of Tomato Plants
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 5.18%.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.
