Forestry Ecology Project Construction and the Sustainable Development of the Huanghe River Delta
JIANG Ze-hui
1999, 12(5): 447-451.
Abstract:
The Huanghe River Delta possesses the very big agriculture development potential, and is the emphatic agriculture comprehensive exploitation area of the nation. Owing to the cause that the forest vegetations decrease on the middle and upper reaches of the Huanghe River,the water resources was seriously wasted etc.,the runoff rate in downstream is decrcased and cutoff. In addition,the restriction of environment factor such as the tide attacking and the salinization of soil and low forest cover rate and the coast moving back etc.,the sustainable development of the agriculture is seriously influenced in this area. On the foundation of systems analysis to the existed problem of the sustainable development of the Huanghe River Delta and the major strategy position of forestry to realize the sustainable development of economy and society in the area, this paper puts forward the directions and tasks of 21 centuries forestry ecology construction in this area.

CHEN Ying-long, GONG Ming-qin, Mark Brundrett, Bernie Dell
1999, 12(5): 452-460.
Abstract:
This paper represents the first part of the results from a glasshouse experiment designed to compare the competition of ECM and VAM fungi on root colonization and effects on growth of two Eucalyptus species (E.globulus and E.urophylla).One ECM fungus(Laccaria lateritia) and three VAM fungi belonging to genera Glomus,Acaulospora and Scutellospora,along with field soil as well,were used to inoculate Eucalyptus seedlings alone or in combination.Both ECM and VAM fungi colonized and formed mycorrhizal associations on roots of inoculated seedlings,though infective rates of VAM and ECM tips per meter varied according to inoculant fungi and plant ages. There were some regressive interactions for colonization between the two fungi,as a general trend for ECM root colonization levels to increase with time at the expense of VAM colonization was observed during 16 weeks. The effect of phosphorus levels in soils on mycorrhizal formation was discussed.

ZHOU Ben-zhi
1999, 12(5): 461-466.
Abstract:
The rule of shooting and height-growth of Dendrocalamus latiflorus was studied in Huaan,Fujian Province during the period from May through October,1995. The results are showed as follows:(1)The process of shooting and height-growth of D.latiflorus can be quantitatively divided into three stages,i.e.initial,abundant and ending stage. The number of shoots at the abundant stage of shooting accounts for 57.48% of the total,and a single shoot at this stage weighs 1.26 kg averagely.The height-growth increment at the abundant stage of height-growth accounts for 81.12% of the total,and the height-growth increment at this stage during one day is 20.44 cm averagely.(2) The process of height-growth of D.latiflorus can be simulated effectively with the models of Logistic and Richards,and the correlation coefficient is high.(3) The leading meteorological factors affecting the height-growth of D.latiflorus are sunshine time,the previous day’s mean temperate and precipitation,and the lowest temperate of current day.Among them,the last one is negatively correlated with the height-growth,the rest of them are positively correlated with it.(4)There are 2 growth peaks within 24 hours in the height-growth of D. latiflorus,i.e.during 6:00~8:00 and 18:00~22:00. The low point is during 14:00~16:00. It grows evenly at night.

1999, 12(5): 474-478.
Abstract:
fertilization tests of different match and ratio of N,P,K were conducted on young Eucalyptus globulus plantation in limestone red soil in Baoshan City for 5 years. The results of tests indicated that fertilization obviously promoted the growth of young E. globulus plantation. At 1.5 years after afforestation,the growth response was at the highest point,the height and DBH of the tree were promoted by 33.69%,48.39% for the 9 manuring treatments. At 5 years after afforestation,the growth response were promoted by 16.45%,10.71% for the 9 manuring treatments. Phosphoric fertilizer is the main factor in promoting the growth of E. globulus plantation.Applying 430 g calcium magnesium phosphate as base fertilizer for each tree,can make the best growth response. The growth responses of N,K fertilizer is not obvious. Organic fertilizer can promot the growth of the trees. Among the 10 treatments,the 3 treatments of No.6 (65 g carbamide,430 g calcium magnesium phosphate),No.9 (130 g carbamide,430 g calcium magnesium phosphate ,54 g KCl),No.10 (treatmet No.9 added with 5 kg organic fertilizer) gained remarkable growth effect. The treatments with best economic benefit are No.6 and No.9.

SUN Xiao-mei
1999, 12(5): 500-504.
Abstract:
The data of thinned permanent plots in Mengjiagang Forest Farm of Heilongjiang Province was used in this paper.Based on the assumption that basal area of thinned stand converge on that of unthinned plantation of the same age,which has the same number of surviving trees on the same site,a basal area growth model for thinned plantation was proposed.The thinned stand development and dynamic thinned procedure were simulated according to the thinned technological measures.
An Application of Linear Model to Testing the Universal Applicability of Site Index Curves for Chinese Fir Provenances
LI Xi-fei, WANG Ming-liang, HUANG Wang-zhi
1999, 12(5): 505-509.
Abstract:
The theory of statistical inferences for linear model was employed to test the effect of Chinese fir provenances on site index curves (dominant height-growth curves).The results of analyzing two experimental farms,Hongya and Jigongshan,showed that,(1)both site indices of different provenances in the same region and those of the same provenances in different regions were both of significant difference,which suggested that variation in site indices was a combination of variation both in genetics and in environment.(2)The slope parameters of site index curves for different provenances were of no significant difference,which meant that the dominant heights of different provenances followed the same growth development.Consequently the dominant height-growths of different provenances could be described by a similar growth model,which provided good evidence in support of the universal applicability of Chinese fir growth and yield models.

ZHANG Zhi-quan, LIAO Wen-bo, CHEN Zhi-ming, MO Bing-you
1999, 12(5): 539-543.
Abstract:
Taxus plants were a kind of important vegetative resources due to that their bark and leaves contain an effective anticancer component taxol. It is very necessary that Taxus planting base was set up,because Taxus population was rare in the natural communities. The cuttings of annual twigs of Taxus mairei without any hormone treatment grow out roots slowly,more than 5 months after have being cut,and their rate of growing roots is lower,only about 30%. In contrast,the cuttings treated with 100~200 mg·L-1 of rooting powder ABT1 and ABT2 can significantly increase 12%~14% of survival rate,83%~98% of rooting rate (percentage),more 60%~107% of rooting number and 60%~103% of total rooting length per rooting cutting.

GU Mao-bin, DENG Yu-sen
1999, 12(5): 552-555.
Abstract:
Eucalyptus,native to Australia,is distributed in natural forests. The insect communication of Australia′s Eucalyptus species is different to that of China. 207 insect species fed by the Eucalyptus,11 of which were belonging to the species of outside flora,and also founded in Australia.Although there are numerous variety of insects in Australia,the relationship between the insect and natural enemy is mutual confine or control and in dynamic balance state. In case these insect infecting into-China,it is completely possible to develop into big disaster due to shortage of natural enemy. Therefor,with a view to protecting occur of insect disease,the best strategy and way is to conduct quarantine on the insect of Eucalyptus.
