초록

비닐피복작물 재배시 시비효율 증대 및 생력시비기술 확립을 위하여 파종과 동시에 시비가 가능한 토중시비기를 개발하였고 개발된 파종기와 시비기를 이용하여 1999년부터 2000년까지 시비간격 30 cm, 시비깊이 15 cm, 파종간격 25 cm로 배수가 양호한 사양토에서 땅콩을 재배한 후 작업정도, 토양화학성, 양분흡수량 및 수량성에 미치는 영향을 평가하였다. 땅콩의 파종 소요시간은 인력($173hr\;ha^{-1}$)에 비하여 90% 이상 노력절감 효과가 있었으나 출현일수는 4일정도 지연되었으며 입모율은 관행구에 비하여 11~18% 낮았다. 시험 전 토양에 비하여 시험 후 토양의 총질소 함량은 증가한 반면에 유기물, 유효인산 및 치환성 칼륨함량은 감소되었으며 토양의 질산태질소 합량은 생육초기에서 중기까지 국소시비구에서 시비량이 많을수록 증가하였다. 땅콩의 질소흡수량은 근류균에 의한 자체 고정량이 많아 시비방법 및 시비량별 큰 차이가 없었으나 인산 및 칼리흡수량은 국소시비 70%, 100%구에서 높은 경향을 나타냈다. 땅콩의 생장속도는 시비방법별 공히 파종 후 120일에 가장 많이 증가되었고 관행시비구와 국소시비 70%구에서 생육후기까지 증가폭이 크게 나타났으며 국소시비 70%구는 협수가 많고 협실비율 및 완숙립중 비율이 높아 종실중이 관행시비구 $3,150kg\;ha^{-1}$에 비하여 4% 증수되었다.

This study was carried out to establish low-input fertilization and seeding technique using the simultaneous with seeding and fertilizer application machine and band spotty applicator which were manufactured for experiment during cultivation of mulching for peanut(Arachis hypogaea L.). The labor hour for seeding by simultaneous with seeding and fertilizing machine was appeared over 90% reduction effect compared with control plot($17.3hr\;10a^{-1}$). In band spotty fertilization plots, the emergence date was delayed about 4 days and the seedling stand rate was decreased 11~18% compared with control plot(man power). The content of total nitrogen of soil after experiment was increased while the contents of organic matter, available phosphate and exchangeable potassium were decreased than before experiment. The content of nitrogen forming nitrate was increased in band spotty fertilization(BSF) plots by increasing the amount of applied fertilizer from early growth stage till the middle growth stage. Growth rate was increased in band spotty fertilization plots and the absorbed amount of phosphate and potassium for peanut were increased in 70% band spotty fertilization plot compared with control plot. Yield of peanut was increased 70% in band spotty fertilization plot due to high pod kernel ratio and ripened pod rate compared with control plot($3,150kg\;ha^{-1}$). It was found that 70% band spotty fertilization was more effective as fertilization method to reduce both environmental pollution and chemical nitrogen fertilizer in plastic film mulching cultivation of peanut.
