- 摘要:
- 转光膜是一种可以转换光质,并且把吸收的太阳光转换成植物光合作用所需光的功能性农膜。以意大利生菜为试验材料,在日光温室条件下进行了转光膜和普通膜对照试验,研究转光膜对温室环境、土壤环境以及生菜生长发育的影响,以期为转光膜在农业发展上提供参考依据。结果表明:转光膜有效提升了温室环境参数,在整个生育期内,转光膜温室的平均空气温度、平均光照强度、平均CO2浓度以及土壤温度较普通膜温室分别提高了2.10%、3.79%、31.73%和3.32%。对于作物生长来说,转光膜温室下生菜的株高、叶长和SPAD较普通膜温室分别提高了3.55%、2.55%和2.42%,生菜平均公顷增产8.54%。整体来看,在转光膜的使用下,温室的空气、光照及土壤环境参数有所提升,进一步促进了生菜生长形态和产量形成。
- Abstract:
- Light conversion film is a kind of functional agricultural film which can convert light quality and absorbed sunlight into light needed by plant photosynthesis.In this study,Italian lettuce was used as the experimental variety to study the effect of light conversion film on greenhouse environment,soil environment and lettuce growth and development,in order to provide a theoretical basis for the development of light conversion film in agriculture.The results showed that the environmental parameters of the greenhouse were effectively improved by the light conversion film.During the whole growth period,the average air temperature,average light intensity,average CO2 concentration and soil temperature of the greenhouse were 2.10%,3.79%,31.73% and 3.32% higher than those of the common greenhouse.For crop growth,the plant height,leaf length and SPAD of lettuce in the light conversion film greenhouse increased by 3.55%,2.55% and 2.42% respectively,and the average yield of lettuce per hectare increased by 8.54%.As a whole,the air,light and soil environmental parameters of greenhouse were improved under the use of light conversion film,which further promoted the growth and yield formation of lettuce.
