In this paper,the biomass increment and the relative biomass accumulation and distribution for Populus tomentosa and its hybrides clones were studied systematically by relative growth method.On the bisis of measured data,the mathematical model for relative biomass among different organs were established.Meanwhile it wasfound that the biomass of different organs for young plantation of Populus tomentosa and its hybrides varied with tree's ages,but the stem biomass held a dominant position.Therefore,this research...

In this paper,the biomass increment and the relative biomass accumulation and distribution for Populus tomentosa and its hybrides clones were studied systematically by relative growth method.On the bisis of measured data,the mathematical model for relative biomass among different organs were established.Meanwhile it wasfound that the biomass of different organs for young plantation of Populus tomentosa and its hybrides varied with tree's ages,but the stem biomass held a dominant position.Therefore,this research provides a theoretical basis for elite variety selection and the formulation of fast-growing and highyield cultivation techniqes.

本文采用相对生长法系统地研究了毛白杨及其杂种无性系生物量增长及其各器官相对生物量的积累和分配规律;建立了干材、干皮、枝、叶、根以及干材、枝与叶等器官间相对生物量的各种数学模型.同时,还揭示出毛白杨及其杂种无性系幼林各器官的生物量因树龄而异,其中,干材生物量占主体.这为良种选育,速生、丰产栽培技术措施制定,提供理论依据.

The fertilizer trial of young clone plantation for Eucalyptus urophylla has been established at Zhenghai Forest Farm in Kaiping of Guangdong Province.The results of trial at 4.5 yearold have showed that there are significant differences on growth among eight fertilizer treatments.Especially in No.4 treatment (N75P200K50),its superior to that of the other seven treatments of fertilizer with the mean height of 15.23 m,mean DBH of 11.07 cm,and volume of 107.5 m3hm-2.There are significant differences between eight...

The fertilizer trial of young clone plantation for Eucalyptus urophylla has been established at Zhenghai Forest Farm in Kaiping of Guangdong Province.The results of trial at 4.5 yearold have showed that there are significant differences on growth among eight fertilizer treatments.Especially in No.4 treatment (N75P200K50),its superior to that of the other seven treatments of fertilizer with the mean height of 15.23 m,mean DBH of 11.07 cm,and volume of 107.5 m3hm-2.There are significant differences between eight fertilizer treatments and the control treatment (no fertilizer).The mean height,mean DBH and volume per hectare of the best fertilizer treatment of N75P200K50 are respectively 1.3,1.65 and 3.1 times that of the control treatment (no fertilizer). The fertilizer treatment of N75P200K50 also has the best economic benefit with a ratio for input and output of 1 to 2.2 and a NPV of 25.96%.

在广东省开平市镇海林场进行了尾叶桉无性系幼林施肥试验,4.5a试验结果表明,8个不同施肥处理(肥料配方)间的生长差异极显著,尤以N75P200K50处理最好,其平均树高为15.23m,平均胸径为11.07cm,每公顷材积为107.5m3。8个施肥处理均与不施肥处理有极显著的差异。最好施肥处理的平均树高、平均胸径和每公顷材积分别是不施肥的1.3、1.65和3.1倍。以最佳施肥处理N75P200K50的经济效益最好,投入与产出比为1∶2.2,与施肥量最高的处理相比,投入少,产出大,内部收益率为25.96%。

The biomass and nutrient contents of Eucalyptus urophylla cl. MLA plantation with early-stage fertilizer trial established at Kaiping, Guangdong, were measured and analyzed at 6 year old. The results showed that fertilizer applied at early-stage promoted the growth and increasing of biomass of E.urophylla cl. MLA plantation. The treatment with the best increment at 6 year old had the biggest biomass with the biomass on ground of 65.95 t·hm~(-2) and stem biomass of 54.94 t·hm~(-2), which were respectively 2.37...

The biomass and nutrient contents of Eucalyptus urophylla cl. MLA plantation with early-stage fertilizer trial established at Kaiping, Guangdong, were measured and analyzed at 6 year old. The results showed that fertilizer applied at early-stage promoted the growth and increasing of biomass of E.urophylla cl. MLA plantation. The treatment with the best increment at 6 year old had the biggest biomass with the biomass on ground of 65.95 t·hm~(-2) and stem biomass of 54.94 t·hm~(-2), which were respectively 2.37 times and 2.36 times that of no fertilizer treatment, and 1.65 times and 1.67 times that of the treatment with the biggest fertilizer quantity respectively. The single biomass and stand biomass of E. urophylla cl. MLA plantation might be forecasted by the regression equation established through height, DBH and biomass. N, P and K in foliage had bigger nutrient concentrations. Fertilizers applied had promoted to absorb and accumulate to nutrient elements for E. urophylla clone.

对建立在广东开平的尾叶桉MLA6年生无性系施肥试验林进行了生物量和养分的测定与分析,结果表明:尾叶桉MLA无性系幼林早期施肥促进了无性系的生长,也促进了生物量的增加。生长最佳的施肥处理N75P200K50,其6年生的生物量最大,地上生物量和树干生物量分别为65 95、54 94t·hm-2,分别是不施肥处理的2 37和2 36倍,分别是最大施肥量处理N75P300K75的1 65倍和1 67倍。通过胸径和树高与生物量建立的回归方程,可预测尾叶桉MLA无性系单株或林分生物量。叶片的N、P、K含量较高,施肥促进了尾叶桉无性系对营养元素的吸收和积累。
