Populs alba X P. glandulosa의 生長과 生産力에 미치는 植栽密度의 效果

任慶彬,宣順和 서울大學校 農科大學 1979 서울대농학연구지 Vol.4 No.2

To estimate the density effect on growth and productivity in Populus alba×P. glandulosa, a series of experiments was carried out in one-year-old cuttig plots with spacings of 30×30, 40×40, 60×60 and 80×80 centimeters, and 6 to 9-year-old plantations with spacings of 2×2, 3×2, 3×3, 4×3 and 4×4 meters. Growth and productivity were determinated by various growth analysis methods and allometric method. Following results were obtained. Experiment Ⅰ 1. Height and diameter growth of cuttings were suppressed by hyperdensity at dense check plots. Diameter growth was affected more by spacing than height growth. 2. In allometry relation of log W=Alog(D²H)+B, D could be substituted by basal ground diameter for DBH. The correlation efficiency of the allometry was very high. The different spacing had different allometry, and the plants of dense check plots consisted with loose organs and thin leaves. 3. Spacing of 60×60 centimeters resulted in best C-D effect and Y-D effect. It would be more reasonable that the initial spacing of intensive short-rotation cultivation to produce fiber materials has the above spacing. 4. LAI had a great influence on the accumulations of both dry matters of a single plant and those of unit area. Excessive LAI brougt about the reduced dry matter assismilation, maximum LAIvalue acceptable was 2.25 in P.alba×P.glandulosa. 5. Through the growth analysis, it was turned out that LAI and LAR had a great influence on growth of P.alba×P.glandulosa. 6. Changes of relative light intensity, air temperature and relative humidity were occured by spacings. The former two factors affected more on growth in experimental plots than the latter one. The strong light intensity and temperature with range of 25℃ to 30℃ resulted in good growth. 7. In this experiments, there was not any struggle for soil moisture by spacing. It was assumed that difference of growth by spacing was the result of difference in ground above conditions. Experiment Ⅱ 1. Although the 6 to 9-year-old stands with densities of 0.526 to 6.7537㎡ of basal area per hectare did not show significant differences in growth by spacing, height growth, diameter growth and slenderness of tree form were accelerated by dense spacing. 2. Crown diameter growth was not affected by spacings. Crown diameter growth was deeply related to diameter growth than height growth, and the linear regression had a similarity among different spacing. Crown closure of the 2×2 meter spacing plot reached to 1.2 value. 3. Growth of bole length to live crown base (clear bole height) was larger in dense plot than that in thin plot. The growth was highly related to height and diameter growth. 4. The allometry equation described as log W=A (D²H)+B had high correlation efficiency by spacings and plant organs. however Allometric coefficient had not significant differences among various densities. 5. Biomass, annual net production and LAI were greater in dense stand than those in thin stand. Dry matter distribution in tree organs was more efficient in dense stand. 6. Multiple regression relation between water content ratio fo stem-wood and tree height and height ratio of collected parts to tree height was highly significant. The height ratio of collected parts to tree height consited the major factor in the regression relation equation. The equation dan be utilized as a conversion factor to estimate the dry matter indirectly. 7. Tree from, C-D effect and Y-D effect performed in check stand, were all good in dense stand. it was expected the dense spacing would be more beneficial in the stand under such cultivation as to yield pulp-wood by first thinning.

The productive structure and the productivity of ×Populus albaglandulosa plantations, where are middle parts of the Korean peninsula, were studied by means of stratifying clip technique and of allometry. The densities of stands in the sample areas were 693 trees/ha in 6 year-old plantation and 527 or 625 trees/ha in 9 year-old one. The photosynthetic part of the productive structure was not shown normal conical form but layering. So this was efficient to transmit solar radiation into the stand floor. The standing crop of the terrestrial parts of 6 year-old plantation was 18.11 ton/ha and that of 9 year-old one 38.8 to 47.3 ton/ha. The wood volume to trunk to 6 year-old was 31.3㎥/ha and that of 9 year-old was 68.8 to 83.9㎥/ha. The annual net production of 6 year-old plantation was 4.8 ton/ha/year and that of 9 year-old one was 10.0 to 11.7 ton/ha/year and its wood volume of trunks was 17.9 to 21.1 ㎥/ha/year. In the 9 year-old plantation the standing crop or the annual net production was different between two sample areas. This seemed that the cause was not due to chemical character but to physical character of soil.

To obtain some informations for the water supply problems of ×Populus albaglandulosa, a series of experiments on the speed of sap movement in the trunk of ×P. albaglandulosa was carried out under the different tree age, soil moisture, time of day, and seasonal condition, by method of injecting of 1% Fuchsin solution. The results showed that the speed of sap movement was great in the conditions of low relative humidity, abundant leaves, and high temperature, but it was less influenced by different tree age and soil moisture.

×Populus albaglandulosa has been needed optimum stand density according to various site and its wood usage. It is assumed that optimum stand density can be estimated by investigating of response of × P. albaglandulosa to the light factor of stand. For that reason, the photosynthesis of ×Populus albaglandulosa grown under the controlled planting density was studied in relation to its leaf age by the aid of the Infrared gas analyzer. Rate of net photosynthesis was smaller in matured leaves than young leaves below 8℃, while, it was larger than young leaves above 8℃. Temperature for the maximum net photosynthesis of young leaves and old leaves was about 30℃ and 25℃ respectively. Saturated light intensity varied slightly as leaf age from 28 Klux to 35 Klux, but net photosynthesis rate in the range of light intensity showed deep differences. Old leaves marked the lowest rate, 1.6 CO₂ ㎎/d㎡/hr, young leaves marked the medium rate, 1.7 to 2.2 CO₂ ㎎/d㎡/hr, and matured leaves marked the most efficient photosynthesis, 2.9 to 3.5 CO₂ ㎎/d㎡/hr. Young leaves of 5 days old had the highest light compensation point, while matured leaves of 35 days-old had the lowest point. Rates of dark respiration in both young leaves and old leaves were higher than that of matured leaves. Trees which were planted at space 80㎝ × 80㎝ showed productive assimilation function over the one-third of height where relative light intensity is 35%.

The results are summerized as follows. 1. Average 13% of supplying double superphosphate was absorbed into ${\times}Populus$ albaglandulosa planted on the reddish heavy clay soil in Institute of Forest Genetics. 2. The accumulation of absorbed magnesium was more amount in leaf than in stem. 3. The uptake ratio of supplying double superphosphate was able to increase up to 16%~33% by the addition of magnesium sulfate to the fertilizer. 4. It might be possible to increase the tree growth following the acceleration of photosynthesis due to the increasing amount of magnesium known to be a component of chlorophyll in leaf as well as to hasten the efficiency of uptake of phosphorus by the addition of magnesium to double superphosphate. 1975년(年) ${\times}$ P. albaglandulosa(은수원사시나무) 0/1묘(苗)를 식재(植栽)하고 방사성동위체(放射性同位體) $P^{32}$-표식(標識) 인산질비료(燐酸質肥料)의 흡수율(吸收率)과 유산고토(硫酸苦土)의 첨가(添加) 시용(施用)에 의(依)한 인산질비료(燐酸質肥料)의 흡수이용촉진효과(吸收利用促進?果)를 시시(試試)한바 다음과 같이 간추릴수가 있었다. 1. ${\times}$ P. albaglandulosa(은수원사시나무)는 구내(構內) 적색계(赤色系) 중점토(重粘土)에서 시용인산질비료(施用燐酸質肥料)의 평균(平均) 13%정도만이 흡수이용(吸收利用)하고 있었다. 2. 흡수(吸收)된 고토분(苦土分)은 줄기보다 주(主)로 잎에 많이 축적되었다. 3. 유산고토(硫酸苦土)를 첨가시용(添加施用)하므로써 시용인산(施用燐酸)의 흡수율(吸收率)은 16~33%선(線)까지 증진(增進)시킬수 있었다. 4. 유산고토(硫酸苦土)를 인산질비료(燐酸質肥料)와 병용(倂用)하므로써 인산(燐酸)의 흡수(吸收), 이용율(利用率)을 증진(增進)시킬뿐만이 아니라 엽록소(葉綠素)의 구성성분(構成成分)인 고토분(苦土分)의 엽내(葉內) 축적량증대(蓄積量增大)는 동화량촉진(同化量促進)과 연결(連結)되어 생장량(生長量)의 증대(增大)도 고려(考慮)될수가 있겠다.
