Abstract

This study was carried out to investigate the hot pepper yield, chemical properties of soil and distribution of animalcule with split irrigation and input of organic matter under no-tillage hot pepper green house condition. After experiment, soil pH maintained range of 5.6~6.2 in whole treatments. Organic matter content of soil was range of $32{\sim}42g{\cdot}kg^{-1}$. Soil salinity (EC) content of soil was range of $1.0{\sim}2.7dS{\cdot}m^{-1}$. Exchangeable cations in soil were range of $0.08{\sim}0.24cmol^+{\cdot}kg^{-1}$ in K, $9.5{\sim}12.8cmol^+{\cdot}kg^{-1}$ in Ca, and $2.7{\sim}3.2cmol^+{\cdot}kg^{-1}$ in Mg. Avaliable phosphorus ($P_2O_4$) content in soil was range of $1,011{\sim}1,137mg{\cdot}kg^{-1}$. Yield of pepper was more decreased in treatment of soybean cake fertilizer than no-treatment of soybean cake fertilizer. Yield of pepper in treatment of soybean cake fertilizer was increased at 33% of standard fertilizer application. Yield of pepper in no-treatment of soybean cake fertilizer was increased at 33% and 66% of standard fertilizer application. Number of fruits was increased range of 12.5~34.9% at half division irrigation compared with whole quantity irrigation. Yield of pepper was increased range of 13.5~34.4% at half division irrigation compared with whole quantity irrigation. Nine index of nature status and 271 Individual were captured in treatment of soybean cake fertilizer. Five index of nature status and 54 Individual were captured in treatment of soybean cake fertilizer. Nature status for environmental change as index organism was 11 points and 5 points, at treatment of soybean cake fertilizer and no-treatment of soybean cake fertilizer, respectively.

본 논문은 한국형 무경운 재배 토양에서 유기물 투입과 분할 관수가 고추 생육 및 수량과 토양 화학성, 생물다양성에 미치는 영향을 구명하고자 추진하였다. 시험 후 토양에 화학성을 조사한 결과 토양 pH는 5.6~6.2, 유기물 함량은 $32{\sim}42g\;kg^{-1}$, EC는 $1.0{\sim}2.7dS\;m^{-1}$, 치환성 K은 $0.08{\sim}0.24cmol^+kg^{-1}$, Ca은 $9.5{\sim}12.8cmol^+kg^{-1}$, Mg은 $2.7{\sim}3.2cmol^+kg^{-1}$ 수준이었으며, 유효인산은 $1,011{\sim}1,137mg\;kg^{-1}$ 수준이었다. 무처리에서 토양에 미소동물은 톡토기와 응애류 등 5종 54개체가 포획되었으나, 대두박을 투입한 처리는 9종 271개체가 포획되어 되었다. 토양환경의 지표가 되는 자연도 점수가 대두박 투입 처리는 11점으로 무 투입 5점에 비하여 2배 정도 증가되었다. 대두박 투입은 무 투입에 비하여 고추의 수확과수의 감소로 수량이 감소되는 경향이었다. 그러나 대두박 무 투입 조건에서 표준시비량의 33~66% 수준에서 고추 수량은 증수되었으며 대두박 투입에서는 표준시비량의 33% 수준에서 증수되었다. 2회 분할관수는 1회 전량관수에 비하여 고추의 수확 과수가 12.5~34.9% 증가되었고, 수량은 13.5~34.4% 정도 증수되었다.
