摘要
设计了一种新型基质槽——聚氯乙烯基质槽,将其放置于日光温室地面上进行草莓基质栽培,研究其节水节肥、保水保温性能及其对草莓生长、品质和产量的影响。结果表明:聚氯乙烯基质槽具有较好的节水节肥、保水保温效果。新型基质槽的浇水量为土栽的45.9%、高架栽培的83.0%、半基质的90.4%;新型基质槽的施肥量为土栽的57.7%、高架栽培的87.0%、半基质的98.5%。通过3种不同容积规格的基质槽对比研究,优选出中型草莓基质槽,其在草莓生长、品质和产量方面都具有明显的优势,特别是春节后每7 d只浇1次水,符合都市农业休闲采摘高端定位,具有较高的推广价值。
A new substrate tank—PVC matrix tank was designed,it was placed on the ground of solar greenhouse for the matrix cultivation of strawberry.Their water-saving,fertilizer-saving,water and heat preservation performance and their effects on the growth,quality and yield of strawberry were studied.The results showed that PVC matrix tank had better effects of saving water and fertilizer,preserving water and heat.The irrigation quantity of new-type matrix was 45.9%of soil planting,83.0%of overhead cultivation and 90.4%of half substrate,respectively.The fertilizer amount of new-type matrix was 57.7%of soil planting,87.0%of elevated cultivation and 98.5%of half substrate,respectively.Through the comparison of three kinds of matrix tanks with different volume specifications,a medium-sized matrix tank of strawberry was screened out,which had obvious advantages in the growth,quality and yield of strawberry.Especially after the Spring Festival,only one watering a week was in line with the high-end orientation of urban agricultural leisure picking,with high promotion value.
