Abstract

This study analyzed the components contained in the pine needles of first and second-year-olds to analyze the factors that the in vivo content of inorganic elements affects the sex determination of pine trees. In response, the plan for pine tree plant and maintenance was intended to be presented in consideration of the reproductive environment and physiological characteristics. The results are as follows. First, last year, when there were many encyclopedias, the analyzed N(%) content was found to be high. The nitrogen content of the previous year's soil was found to affect the production of the spheres the following year. This is believed to be possible to reduce the rate of Pine pollen produced in the new plant in the following year through a dispute over quality consumption in the spring of the previous year. Second, the weapons elements involved in the Pine cones and the generation of the Pine pollen in the new plant appeared to be P(%), K(%), Ca(%), and Fe(%). However, the nutrients from the previous year's leaves of Ca(%) and Fe(%) were found to have a low influence on the sex determination of first-year pine trees. Because Ca(%) and Fe(%) are not able to move nutrients accumulated in aging organs due to the nature of the components, feeding nutrients in the fall when the growth of the previous year's branches is reduced is expected to affect oral generation. Third, pine trees are extremely positive and Pine pollen is related to the time of the northeast wind. Therefore, it is believed that it would be good to be located in the northern direction, where the sunlight is good, in an outdoor space. In addition, it is important to use vaginal consumer products in spring and carry out a quarrel involving Mg and Fe during fall to reduce the effect of the Pine pollen, which is an outdoor plant. This is an important part of maintaining and managing pine trees in outdoor spaces as well as the sex determination of pine trees. This study suggested that plant planning, which derives the correlation between pine inorganic element content on sexual determination and takes into account the physiological characteristics of pine trees, is an important issue in the creation of outdoor space. Follow-up research on other factors affecting pine tree sex determination is expected.

본 연구는 무기원소의 체내 함량이 소나무의 성 결정에 미치는 요인을 분석하기 위해 1, 2년생 솔잎에 포함된 성분을 분석하였으며, 이에 생육환경과 생리적 특성 고려한 소나무 식재계획 및 유지관리 방안을 제시하고자 하였다. 그 결과는 다음과 같다. 첫째, 구과가 많이 맺힌 작년가지의 잎에서 분석된 N(%)함량이 높은 것으로 나타났으며, 작년토양의 질소성분은 다음 연도 구과의 생성에 영향을 주는 것으로 파악되었다. 이는 전년도 봄에 질소비료를 이용한 시비작업을 통해 다음해 신초에서 생성되는 송화비율의 저감이 가능할 것으로 판단된다. 둘째, 1년생 가지의 구과 및 송화가 열리는데 관계하는 성분은 인산(P), 칼륨(K), 칼슘(Ca), 철(Fe)이 유의미한 것으로 파악되었으며, 전년도에 생성된 Ca과 Fe는 신초의 성 결정에 낮은 영향력을 보이는 것으로 나타났다. Ca과 Fe는 노화된 기관에 축적된 영양소의 이동이 어려운 특성을 지니므로 이듬해 봄철 구과생성에 영향을 미칠 수 있도록 전년도 가을에 양분을 공급을 주어야 할 것으로 생각된다. 셋째, 소나무의 송화가루는 봄철 북동풍이 부는 시기와 관련 있고 극양수의 속성을 지니므로 옥외공간에 식재할 때 볕이 잘 드는 북향이 적합한 것으로 판단된다. 또한 조경공간에 식재된 송화가루의 저감효과를 위해 봄철에 질소비료로 양분을 비축하고, 가을철에 Mg, Fe성분이 포함된 시비작업을 실시하는 것은 소나무의 성 결정 뿐만 아니라 소나무의 유지하고 관리계획에 고려되어야 할 사안으로 보인다. 본 연구는 소나무 무기원소 함량이 성 결정에 미치는 상관관계를 도출하고 소나무의 생리적 특성을 고려한 식재계획은 옥외공간 조성에 있어 중요한 사안임을 밝혔으며, 기타 소나무 성 결정에 영향을 주는 요인을 주제로 한 후속연구가 기대되는 바이다.
