  masson pine
Organic acid exudation from the roots of Chinese fir (Cunninghamia lanceolata) and Masson pine (Pinus massoniana) seedlings under low phosphorus stress was studied using the solution culture method.
      
The results revealed that organic acid exudation from the roots of Chinese fir and Masson pine seedlings under low phosphorus stress increased.
      
Compared with P3 (KH2PO4, 0.5 mmol/L), the average organic acid exudation from the root of Masson pine seedlings under P0 (KH2PO4, 0 mmol/L), P1 (KH2PO4, 0.03 mmol/L) and P2 (KH2PO4, 0.09 mmol/L) increased by 328.6%, 267.9% and 126.4% respectively.
      
Masson pine from Zhejiang Province in China had the highest organic acid exudation.
      
Under low phosphorus stress, the increase in organic acid exudation from the different provinces of Chinese fir and Masson pine varied.

The selection of appropriate speed of rotation of the band saw wheel is closely related to the increase in production and the improvement in quality of lumber and to the decrease of electricity consumption.

选择适宜的带锯轮转速(切削速度),对提高锯机产量、锯材质量以及降低锯材单位面积上的电能消耗都有密切的关系。 作者在不同转速(切削速度)的带锯机上对锯材表面粗糙度、加工误差以及锯材单位面积上的电能消耗进行了测定。据此分析并推算了锯割马尾松材适宜的锯轮转速(切削速度)以及不同切削速度的进料速度和切削高度的临界值。

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...

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。

Experiments on drying the lumber of Firms Khorajensis Sieb. et Zucc. and P. massoniana Lamb, of 20-55 mm thickness by using far-infrared rays were made. Forced draught equipment was employed in the kiln to improve the evenness in drying. Results proved to be satisfactory.

对红松、白松、马尾松等厚度为20—55毫米的板材进行了电热远红外干燥试验,干燥质量多数良好。窑内采用了强制通风设施,改善了干燥均匀度。 试验发现,在这一干燥技术中起主导作用的仍是介质的对流传热,而不是红外辐射,辐射能的利用大约不超过5%。如何正确评价和运用远红外干燥技术,是值得讨论的。
