The blister rust of Mongolian pine is an important disease. The pathogenic fungus is identified as Cronartium flaccidum (Alb. et Schw.) Winter, its telia host under natural conditions in Heilongjiang Province is Paeonia species. The fungus also infects Melaplexis japonica under inoculation. The spreading period in woods for its aeciospore is 56 days and the spore can be caught at the distance of 30m, the vertical is about 5m high with abundant collection of spores. Aeciospore is binucleate, only one germ tube has priority to grow. On the 2% agar water membrane with temperature 20℃ under saturated moisture, and pH about 7 the germination rate reached 80%. The germination rate of uredium can be raised about 15% if exposuring in the sunshine before germination. The germinating rate of urediospore, on 2% agar water membrane under 25℃, reach 78.4% for 48 hours. The overwintered urediospore on diseased leaves of Paeonia species still can germinate (2.96%) and infect. The teliospore will mature in three days after its formation and then germinate under the temperature 16—21℃ and 3 hours wet condition, producing basidiospores. Hyphae beneath the canker bark of Mongolian pine are perennial, septate, monocaryotic, and grow between host cells, entering cells to form haustoria. Some weed killers may eradicate Paeonia leaves. Using 10%, 20% NaCl solution or 5—10 grams, 10—20 grams of NaCl crystal to spread around the roots can kill Paeonia roots. Smearing chemical medicine on the surface of diseased stems, such as N-dodecyl-12.6-dimethyl morpholine (1000 times), the solution of creosote and machine oil mixed with corn germ oil (1:3 or 1:5), will kill aeciospore although there are chemical harm for twigs and young branches. Pruning including cutting off diseased shoots is an ideal measure to promote the growth of forest trees and the disease prevention.

樟子松疱锈病是樟子松人工林的重要病害。病原菌为松芍柱锈菌[Cronartium flaccidum(Alb. et Schw.)Winter],其冬孢子寄主为芍药[Paeonia lactiflora]及山芍药[P. obovata],人工接种还侵染萝藤(Melaplexis japonica)。锈孢子放散56天,5月15日至6月20日为放散高峰期,水平传播30米,垂直分散5米。锈孢子双核,具2—4芽孔,只有1芽管优生,在2%琼脂膜上,20℃,饱和湿度,pH7时萌发率达80%。夏孢子经阳光照射可提高萌发率15%,在2%琼脂膜上,25℃下,4小时始萌发,48小时萌发78.4%;越冬后的夏孢子具2.96%萌发力。冬孢子成熟后3天在16—21℃下,保湿3小时即萌发,24—36小时萌发量最大。在樟子松病皮下的菌丝为多年生,有隔,单核,在寄主细胞间隙生长,以棒状或丝状吸器伸入细胞吸养。用氯化钠水溶液或结晶可杀死芍药根;用十二吗啉千倍液涂干效果好,松焦油,焦化腊、机油加玉米荠油均有效,但产生药害。修枝是促进林木生长和防病的理想措施。

Constraction of protective forest in Hexi corridor is considered a major one among all the projects in the northwest, north China and northeast.The grasses interplanted with trees under the forestation belt not only raise soil fertility and promont the growth of trees but also enrich the forage grass and bring about a great advance in animal husbandry in rural area.The studies on the fertility different types of soils have been performed with sampling for examination and test and using statistical analysis matched by comparison from 1983 to 1985,The results show that there have been a remarkable influence upon content of soil organic matters and effective potassium,in particular,and also upon the total nitrogen and nitrogen hydrolysate.As for effective phosphorus, such effects have not been found yet during the2—3 year of grass growing.

西北、华北,东北防护林建设的重点工程是在河西走廊建设农田防护林。实行林带种草对于提高土壤吧力、促进林木生长效果良好,还可扩大饲草来源,促进农区畜牧业的发展。本文报道作者1983—1985年期间对河西走廊农田防护林带种草的调查研究。对种草林带不同类型土壤的肥力状况采样化验,并用配对比较法统计分析结果表明;林带种草对土壤有机质含量的影响显著;对全氮含量的影响极显著:对水解性氮的影响极显若;对有效钾的影响显著;林带种草2—3年内,对有效磷含量的影响还不显著.

An irrigation experiment was conducted in an intensively cultivated poplar plantation (Populus dcltoidrs Bartr. cv. "Lux" ex. I-G9/55) in 1983-1986. The relationship between the indices of tree growth, water physiological indices and water supply in the field was studied. The results reveal that artificial water supply can greatly promote the growth of tree. In comparision with the control (rainfall only) the average height, D. B. H. and volume increment increased by 17.2-24.6%, 10.7-22.1% and 22.0-42.6% respectively...

H. and volume increment increased by 17.2-24.6%, 10.7-22.1% and 22.0-42.6% respectively under irrigation. Water supply has a great influence upon the structure of tree, increasing dry weight of stem and branch, leaf number and leaf area, favouring the accumulation of assimilation and it's transport to branch. The enlargement of leaf area of crown promotes the increase of volume increment.

在集约栽培的杨树人工林中作了小区灌溉试验,进行了林木生长指标、水分生理指标与供水量关系的研究。结果表明,供水大大促进了林木生长,其树高、胸径和材积的年增长量均随供水量的提高而增加。1983—1986年其树高、胸径、材积分别比对照增加 17.2—24.6%、10.7—22.1%和22.0—42.6%。供水还影响到树体的结构,有利于同化产物向枝条中运输与积累,促进了树干、枝条、叶数与叶面积的增长。
