有机物料种植板栽培对日光温室辣椒生长与生理特性及产量品质的影响OA

Organic substrate planting board(OSP)cultivation is a novel cultivation model designed to achieve automated operations in facility vegetable cultivation.To investigate the effects of this model on the growth,yield,and quality of fruit vegetables,in this study,a pepper cultivar Zhongjiaoniujiao 1 was used as the test material.From 2023 to 2024,in a solar greenhouse,the influence of OSP cultivation(using a mixture of waste seedling substrate,decomposed sheep manure,and decomposed corn straw at a volume ratio of 3:2:1,OSP)and conventional cultivation,where organic materials were broadcast-applied followed by deep ploughing and ridge formation(CK)on growth,physiological characteristics,yield,and quality of pepper was compared and analyzed.The results showed that over the two experimental years,the growth vigor of peppers under the OSP treatment was superior to that of CK.Specifically,in 2023,plant height and stem diameter increased by 4.13％-15.37％,3.00％-23.94％,respectively;over the two years,the dry weights of stems and leaves increased by 4.03％-28.40％and 4.14％-14.11％,respectively.Regarding physiological indicators,the OSP treatment significantly enhanced root activity,chlorophyll a and chlorophyll b contents,net photosynthetic rate,and stomatal conductance,with increases over the two years ranging from 7.21％-9.50％,10.50％-32.22％,9.50％-24.04％,16.71％-22.66％,and 23.03％-49.4％,respectively.In terms of yield and quality,compared with CK,the OSP treatment significantly increased the number of fruits per plant and single fruit weight,leading to a significant increase in yield per hectare,with yield increases of 28.38％in 2023 and 12.69％in 2024.Furthermore,peppers grown under the OSP treatment exhibited superior appearance quality(e.g.,fruit length,fruit firmness)and internal nutritional quality(e.g.,soluble sugar,vitamin C,and soluble protein content)to those of CK.In conclusion,the OSP cultivation could effectively improve the physiological and growth characteristics of peppers in solar greenhouses,enhance yield and fruit quality,and meet the objectives of high quality and high yield in facility vegetable cultivation.
