不同地面覆盖方式对日光温室内二氧化碳浓度与番茄生长的影响
Effects of different ground mulching methods on carbon dioxide concentration in solar green-houses and tomato growth
摘要
Abstract
To address the issues including CO2 deficiency induced by poor ventilation in solar greenhouses during au-tumn and winter in northwest China,the tomato cultivar Jintao 19 was used as the test material.Five treatments were established in the solar greenhouse:CK1(bare soil without mulching),CK2(plastic film mulching on ridges),T1(plastic film mulching on ridges+straw mulching in furrows),T2(straw mulching on ridges),and T3(full straw mulching).The growth and development of tomato plants,as well as the CO2 concentration and distribution in the greenhouse,were determined to screen the optimal ground mulching regime.The results showed that compared with CK1,the CO2 concentrations at the near-ground layer,canopy layer,and upper canopy layer under T1 were signifi-cantly(p<0.05)increased at 13:00,21:00,01:00 and 05:00.The contents of chlorophyll a and chlorophyll b were significantly elevated,the plant height,stem thickness and leaf number were significantly enhanced,and the contents of nitrogen(N),phosphorus(P),and potassium(K)in stem and leaf,as well as P and K contents in root,were also significantly increased under T1 treatment than those under the CK1 treatment.The net photosynthetic rate,stomatal conductance,intercellular CO2 concentration,root activity and root volume were significantly increased by 53.12%,10.34%,53.64%,5.10%,70.34%,respectively,under T1 treatment than those under the CK1 treatment.In conclusion,plastic film mulching on ridges combined with straw mulching in furrows can promote tomato growth and dry matter accumulation by elevating CO2 concentration in the greenhouse and enhancing plant photosynthesis.关键词
