Abstract
A survey on the vinyl house soils was conducted to investigate the salt accumulation status and it's effects on the deterioration of soil aggregates. The survey was made for the vinyl house soils in Suwon, Yesan, and Kimhae areas where vegetables are extensively grown under a vinyl house. Physical and chemical properties of the soils at the inside and outside of the vinyl house were compared to continuous vegetable cropping. Electrical conductivity of the soil solution (Y) in vinyl house was closely related to the number of cropping years (X), and the relations are given by the following regression equations:
비닐하우스 재배지(栽培地)에 대(對)하여 토양(土壤)의 성질(性質), 토양관리양식(土壤管理樣式) 및 연작(連作)이 토양염류(土壤鹽類) 집적(集積)에 미치는 영향(影響)과 염류(鹽類)의 집적(集積)이 토양(土壤)의 성질(性質)에 미치는 영향(影響)을 구명(究明)하기 위(爲)하여 비닐하우스내(內) 토양(土壤)과 비닐하우스외(外) 토양(土壤)의 이화학적(理化學的) 성질(性質)을 조사(調査)한 결과(結果) 다음과 같다. 1. 비닐하우스내(內) 토양(土壤)의 염농도(鹽濃度)가 하우스외(外) 토양(土壤)의 염농도(鹽濃度)보다 높았으며, 심토(心土)보다는 표토(表土)에서 높았다. 2. 하우스내(內) 토양(土壤)의 표토(表土)에서 염농도(鹽濃度) (Y)는 연작년수(連作年數)(X)와 다음과 같은 회귀관계(回歸關係)가 성립(成立)되었다. 양질토(壤質土); Y=0.54X+1.44 (
