Effect of Boron Contained Compound Fertilizer on Chestnut Trees

밤나무 전용복비(專用複肥) 비효시험(肥效試驗)

Newly manufactured compound fertilizers for chestnut trees developed by Chosun Fertilizer Inc. were tested to evaluate their effectiveness. An experiment was carried out in chestnut farm with 4 years old Eungi Var. from 1981 to 1982. The results obtained are as follows: 1. The growth of chestnut trees was generally good in plots of compound fertilizer contained boron (B C F). 2. The number of ripened strobiles was significantly increased by reducing the ratio of dropped strobiles in plot of B C F. 3. The yield of chestnut by B C F was markedly increased, 6 times more than that of compound fertilizer without boron. 4. Boron content in soil and plant by application of B C F was relatively high, resulting in high production of chestnut. 5. B C F was effective in chestnut orchard to increase nut production markedly.

밤나무에 대(對)한 합리적(合理的)인 시비(施肥)를 목적(目的)으로 밤나무 전용복비(專用複肥)를 관발(關發)하여 1981-1982년(年)에 걸쳐 은기품종(銀寄品種)을 공시(供試)하여 여비시험(旅肥試驗)을 한 결과(結果)는 다음과 같다. 1. 밤나무의 생장량(生長量)은 함붕소복비구(含硼素複肥區)에서 대체(大體)로 양호(良好)하였다. 2. 함붕소구(含硼素區)에서는 낙과방지효과(落果防止效果)가 커서 성숙구(成熟毬) 과수(果數)가 현저(顯著)하게 많았다. 3. 밤수량(收量)은 1982년도(年度) 경우 함붕소복비구(含硼素複肥區)에서 매우 높아 일반복비구(一般複肥區)에 비(比)해 6배(倍)나 되었다. 4. 함붕소복비시용(含硼素複肥施用)으로 토양(土壤) 및 식물체중(植物體中)의 붕소함량(硼素含量)이 높았으며 이는 밤나무의 생장촉진(生長促進), 낙과방지(落果防止)에 영향을 주어 밤 증수(增收)에 기여 하였다고 판단(判斷)된다. 5. 밤의 획기적증수(劃期的增收)를 기(期)하기 위(爲)하여는 밤나무 전용복비(專用複肥)의 시용(施用)은 불가피(不可避)한 것으로 생각된다.
