不同产地岩棉培番茄试验研究
Experimental Study of Tomato Growth in Rock Wool Culture with Rock Wool from Different Production Places
,
摘要:

为了降低岩棉投入成本、提高经济效益并了解国产岩棉在无土栽培中的应用效果,进行了不同产地的岩棉培番茄对比试验。试验结果表明:使用大连国产岩棉能降低生产投入成本39.48%,增加收入8.68%;产量比对照降低5.19%,达5%显著水平;能增加有效花穗数、平均果实数量、果实串数、单果重,但果实品质有所降低;基质内电导率不稳定,变化较大;使用荷兰进口岩棉虽然植株生长发育状况好于大连国产岩棉、产量高,但因投入成本高,纯收入低于使用大连国产岩棉。

Abstract:

In order to reduce the input cost of rock wool, improve economic performance and understand the use effect of domestic rock wool on soilless culture, a comparative experiment of tomato growth in rock wool culture with rock wool from different production places is carried out. Experimental results show that use of rock wool made in Dalian, China can reduce input cost by 39.48%, and increase income by 8.68%; yield is lower by 5.19% than output of contrast, reaching the 5% significant level; productive panicle number, average quantity of fruit, quantity of fruit cluster and single fruit weight are increased, but fruit quality is decreased; electric conductivity in matrix is not stable, and has a large variation; by using rock wool imported from Holland, the growth and development conditions of plant is better than that using rock wool produced in Dalian, China and the yield is higher, but net income is less than that using Dalian rock wool.
