비옥도가 낮은 해성충적토인 퇴화염토답에서의 실소수준을 달리한 조건하에서 규회석의 시용량을 달리하였을 때 이들이 수도생육 및 수량에 미치는영향을 구명코자 시도한 바 다음과 같은 결과를 얻었다. 1. 규회석의 시용효과는 전반적으로 N 12kg/10a 구보다 실소량을 증시한 Nl6kg/10a 구에서 뚜렷한 효과를 보이고 있었다. 2. 류회석 처리구는 수도생육 경과중의 하엽고사 및 도열병피해의 경감, 유효다비율 및 등숙비율의 향상, 정조천립중을 높일 수 있였다. 3. 출수기 엽위별 SiO_2의 함량에 있어서는 규회석 시용구이 낮은 200kg/10a 수준에서는 지엽으로부터 차엽의 순으로 함량이 낮아지고 있었으나 400kg/10a 이상의 시용구에서는 단위에 따라 함량의 변이가 크지 않았다. 4. 출수기 도체내의 SiO_2함량과 등숙률(r =0.613) 및 지엽내의 SiO_2함량과 등숙률(r=0.407)과는 정의 상관관계가 인정되였다. 5. 수상조사결과 규회석 처리가 일차지경이나 이차지경의 분화 및 퇴화에는 그댜지 크게 영향하지 않은 것으로 보였으나 홍화의 분화 및 퇴화에 영향하고 있음이 인정되었다. 6. 수량과의 관계를 살펴보면 실소률 증비한 N16kg/10a 수준에서 증수효과가 뚜렷하였고 규회석 시용률에 있어서는 400/200kg\leq200\leq400 < 600kg/10 a 순으로 증수되었다. This study was conducted to find out the effect of wollastonite application in degraded saline soil condition on the growth of japonica rice variety. The variety, Palgweng was tested with 4 levels of wollastonite (200, 400, 600 and 400/200 kg/l0a) and two nitrogen levels (12 and 16 kg/l0a). The effect of wollastonite was higher in 16 than 12 kg of nitrogen application. The wollastonite application reduced rice leaf blast and dead left at lower nodal position, and increased percentage of effective tillers, percentage of ripened grains and 1, 000 grain weight. The SiO$_2$ content of upper leaf was higher than lower leaf in 200 kg of wollastonite application, but there was no difference under high wollastonite application (400 kg/l0a). Highly significant positive correlationships were obtained between SiO_2 content of plant at heading and percentage of ripened grains, (r=0.613) and SiO_2 content of flag leaf and percentage of ripened grains (r=0.407). Wollastonite application did not affect the development and degeneration of primary and secondary rachis branches of panicles, but it increased the number of spikelets. The highest grain yield was obtained with 16 kg of nitrogen and 600 kg of wollastonite.
