Studies on the Improvement of Mountainous Pasture III. Effect of seed coating on oversown pasture
산지초지 개량에 관한 연구 III. 종자 Coating에 의한 겉뿌림 초지육성
Abstract
Effects of seed coating on establishment, early growth and herbage production were investigated in Pot, Soil box and Field experiments. Seed was coated with 60% Lime, 20% Phosphate and 20% Peatmoss(W/W), also finely sprayed 13% Arabic gum and 2% Methyl cellulose(W/V). Coating were generally 1:20, seed: coat(W/W). 1. In the general growth of the growing stages and different oversown species at 80 days, seed coated was promoted than none in early growth. (Table 2 and 3) 2. Stand counts at 60 days after oversown, seed coated was higher 15% than none, especially, there was advantage due to coating on the medium and large size seeds such as Orchardgrass, Perennial ryegrass and Kentucky bluegrass, but did not assist establishment of the large (Tall fescue) and small (Ladino clover) size seed. 3. Variation of sward composition was not quite different between two treatments, but seed coated was slightly increased the Percentage of sown grasses with advance of cutting time. 4. Total dry metter yield per unit area with seed coated was higher 17% than none in establishment year. 5. Variations in the chemical composition of the herbage and soil were influenced by coating materials in the coating regime (Table 8). 6. From these facts, seed coated also appeared that adequate seedling stands, early growth and herbage production could be obtained with higher than conventional overseeding method under a poor conditions.
종자(種子) coating이 겉뿌린 목초(牧草)의 정착개체수(定着個體數), 초기생육(初期生育) 및 수량(收量)에 미치는 영향을 구명(究明)코저 60% lime, 20% Phosphate 및 20% peatmoss(w/w)의 증량피복재료(增量被覆材料)와 13% arabic gum및 2% methyl cellulose (w/v)를 접착제(接着劑)로 사용(사용)하여 종자(種子)와 피복재료(被覆材料)의 무게 44를 1 : 20(w/w)으로 coating하여 pot, soil box 및 field에서 시험(試驗)한 결과(結果)는 다음과 같다. 1. 종자(種子) coating은 겉뿌린 수준(水準)의 초기(初期) 생육(生育)을 촉진(促進)하였다(Table 2와 3). 2. 종자(種子) coating은 겉뿌린 목초(牧草)의 초기(初期) 정착개체수(定着個體數)를 15%정도 증가시켰고, orchardgrass, perennial ryegrass 및 kentucky bluegrass의 정착개체수(定着個體數)를 증가시킨 반면 대립종(大粒種)의 tall fescue 및 소립종(小粒種)의 ladino clover에는 큰 차이(差異)가 없었다. 3. 종자(種子) coating은 겉뿌린 목초(牧草)의 식생비율(植生比率)을 증가시켰다. 4. 종자(種子) coating은 겉뿌림 초지(草地)의 조성당년(造成當年)의 건물수량(乾物收量)을 17%정도 증가시켰다(P<0.05). 5. 종자(種子) coating시(時) 증량피복물질(增量被覆物質)은 토양(土壤) 및 식물체(植物體)의 화학성분(化學成分)에 영향을 주었다(Table 8). 6. 환경조건이 불량(不良)한 지역(地域)에서의 겉뿌림 초지개량시(草地改良時) 종자(種子) coating은 관행적(慣行的)인 겉뿌림 방법보다 목초(牧草)의 정착개체수(定着個體數), 초기생육(初期生育) 및 수량(收量)을 증가시킬 수 있는 확실한 방법(方法)이라 할 수 있다.率)과의 관계를 주의깊게 고려해야 할 것이다. 생산(生産)할 수 있다고 사료(思料)된다.향이 없었으나 골목
