The present investigation was made in the course of three years (1961—1963). Thirty-two plots,each of 2—3 mou,in Pinus massoniana stands were selected for esti- mating the fluctuation of population of this serious pest.The estimations comprised of several items,such as sex ratio,fecundity,mortality and others. Based on the results of observations,it was found that in the hilly areas of Kiangsf Province,the outbreak of this pest seemed to be of intermittent epidemic type.The out- break intensity,as measured by the number of generations between two successive out- breaks,varied from 2 to 3 or more generations. The population clensity varied from generation to generation. As a rule, the first generation had the highest population density, and the overwintering generation the low- est. The population density of each generation was mainly decided by the mortality of the first three instar larvae. No close relationship between populations of two successive generations was found. In those areas where there were 2—3 generations a year,the larvae of the second generation when developing to fourth instar,differentiated into two groups.The larvae of the one group went into diapause right away and those of the other continued to de- velop and overwintered as 3rd instar larva in the third generation.The number of larvae in each of the two groups varied with environmental conditions.The ecological significance of this phenomenon should be studied further.But based on the results of examinations,it was found that this phenomenon exerted no influence on the population change of the overwintering generation. Besides the human effect,there were three factors affecting the population changes, namely the climatic,food and natural enemy factors.The effect of climate on popula- tion fluctuation was found to have been greater than that of the food or of the enemies. In Kweichi,Kiangsi,the precipitation in May and in August exerted a decisive effect on the occurrence of outbreak in a year.The food factor affected the population change only in certain localities where the pine needles were completely consummed by this pest. The natural enemies exercised a great effect on the population immediately after the collapse of the outbreak. The number of generations completed in one year varied from the south to the north.There were 3—4 generations in Canton,Kwantung Province,while in Hsinyang, Honan Province only 2—3 generations a year.The highest fecundity was 881 eggs per female with an average of 681.5 eggs.But in general,a female laid only 200—300 eggs.

本文根据几年来研究结果,就马尾松毛虫发生动态进行初步分析,以便了解其一定规律,而为测报及防治提供依据。本种害虫发生时期虽因地而异,但在同一地区,其各虫态各年中发生期的变幅,并不算大。根据发生危害情况,可将本种害虫发生地区分为三类,即(1)深山安全地区,(2)浅山偶发地区,及(3)丘陵猖獗地区。把发生地区按照这一情况划分,对防治本种害虫,颇有实际意义。本种害虫种群数量季节变动,有其一定规律性。一年中第四龄幼虫发生数量以第一代最多,第二代灰之,越冬代最少。各世代数量的多少,对于其下一代数量的变动,并无显明的相关性存在,下一代数量多少,主要以其1一3龄幼虫死亡率大小为转移,死亡率小,下一代数量多,反之则少,由此可知当代第四龄幼虫数量是决定各该代数量多少的比较可靠的依据。越冬代数量多少,对于次年春季越冬代大发生有决定性作用,因一般越冬死亡率不大。预测发生数量,对上述事实,必须加以重视。影响马尾松毛虫发生的因素,主要有气候、食料及天敌,而以气候影响范围较大,食料及天敌则只有在局部地区起作用。

The chemical constituents of conifer needles (Pinus massomana Lamb., P. taiwanensis Hayata, P. densiflora S. et Z., P. thunbergii Parl., P. koraiensis Sieb. et Zucc. and Abies holophylla Maxim.) were determined. The results showed that pine needles contain abundant nutrient substances including carotene 70-340 nig/kg, 17 or more amino acids in crude protein and various kinds of mineral elements. The biologically active substances extracted from needles and the needle meal were used as additives to poultry and other livestock feeds. When poultry were fed with composite feeds containing 0.02-0.05 weight percent of biologically active substances, increases of body weight (8-17%), the rates of egg production (9~19%), fertilization and incubation and colouring material of egg yolk based on control were resulted, susceptibility to disease was reduced and the feed consumption was saved by 8-28%. Adding 2.5-4.5% of needle meal to the feed for pigs, 15-30% weight increase was obtained.

测定了我国马尾松(Pinus massoniana Lamb.)黄山松(P.taiwanensis Haya-ta)赤松(P.densiflora S.et Z.)黑松(P.thunbergi Parl.)红松(P.koraiensis Sieb.et Zucc.)和辽东冷杉(Abies holophylla Maxim.)针叶的某些化学成份,确定松针叶营养成份丰富,胡萝卜素含量达70—340毫克/公斤,马尾松针叶粗蛋白质中氨基酸至少有17种,还含有各种矿物元素等。 研究了松针生物活性物质和松针粉饲喂畜禽的效果。一般的情况下,在家禽配合饲料中添加0.02—0.05%,松针生物活性物质,各类雏禽体重可增加8—17%,家禽产蛋率可提高9—19%,饲料节省8—28%,且能增强家禽抗病力,还可提高家禽的产蛋率、受精率、孵化率和蛋黄色素。在猪的日粮中添加2.5—4.5%松针粉,猪的增重率比对照组提高15—30%。在种鹅日粮中添加10%松针粉,不影响种鹅的产蛋和体重。 经石油醚和水萃取后的松针残渣亦能够用来代替统糠作种鹅的填充饲料。

The authors'experiments proved that ectomycorrhizae may improvethe early growth of Pinus tabulaeformis.It obviously stimulates thebiomass production of pine seedlings.The approximate percentage ofincrease is 40%. Among the mycorrhizal fungi used in our experiments,five wereselected as good ones which are capable of forming ectomycorrhizae andstimulating growth of P.tabulaeformis seedlings,i.e,Boletus sp.,suillusgrevillei,Pisolithus tinctorius,and strains obtained from the ectomycorrhizalassociation of loblolly pine and scotch pine trees. Biological analysis in greenhouse studies shows that all speciesmentioned above,whether collected from mycorrhizae association or frommature fruitbodies of fungi,can easily from ectomycorrhizae with P.tabulaeformis. The results of experiments show that by inoculum of solid pureculture,mycorrhizal fungi on roots have a great capacity to establishectomycorrhizae of coral type.The stimulation of seedling growth(including measurements of height,thickness and biomass)is proportionalto the development of mycorrhizae on it. The fact that acid soil conditions are needed for the formation ofectomycorrhizae is well documented throughout the world.Usuallyectomycorrhizae develops either weakly or not at all basic soil.But inthe authors' experiments mycorrhizae are formed both in nursery soil(pH8.6) and in greenhouse soil (with alkalinity of up to 8.9),and canimprove the growth of seedlings well.It has been proved by theseauthors that even under harsh soil conditions suitable strains cansurvive and grow significantly.This fact enlarges the area of potentialresearch into the ability of fungi to survive in adverse soil conditions. The ingredients of the nutrient medium are as follows:1) pine needle extract,2)acidic malt agar.

本试验验证了菌根化能促进油松苗木早期生长,对其生物产量有明显提高。优良菌种可使苗木干物重提高40%。试验筛选出Boletus sp.(林)、Suillusgrevillei(林)、Pisolithus tinctorius及“火炬松”、“欧洲赤松”等五个菌种在促进苗木生长方面有良好效果。经温室生物测定,不论是从菌根组织还是直接从子实体上分离到的菌种,接种后均能与油松根很好地形成菌根。用生长优良的固体纯培养物接种后,油松苗形成菌根的能力很强,多数产生茂盛的珊瑚状菌根组织,苗木的菌根化程度与其对生长的促进作用(包括干物重、高及粗生长)基本上呈正相关。在碱性及接近重碱性土壤中苗木均形成了菌根,并较好地起到促进生长作用,扩大了菌根菌抗逆性的筛选内容。试验筛选出适合菌根菌生长的培养基以及用于接种的纯培养物的载体。
