《新民周刊》在大雾里呼喊"我在雾里呼喊,我在雾里呼吸。我在雾里活着,不想雾里死去。我在雾里奔波,我在雾里哭泣。我在雾里挣扎,不想雾里窒息"。一曲大雾版《北京北京》,唱出了人们心底的悲怆。蓝天白云,心旷神怡——这是2008的北京留给人们的美好记忆。在重重雾霾笼罩之下,我们多么希望能穿越到那个神清气爽的夏天,

人生如树

树是大自然赐予大地的最普遍的植物,在浩瀚的森林,在广袤的原野,在陡峭的悬崖,在田间地头,在乡村人家到处都能看到树那婆娑多姿的身影. 生在鲁北平原的我,有幸看到明显的四季轮回,也能在这四季轮回里看到树木由春天的一点新绿直到变成冬天质感的躯体,其实树一年的荣枯像极了人的一生,但是树比人要好的多,那就是树能在四季的更替中得到重生,而人生只是一辆单行车,没有办法逆行.

漫步森林中

我喜欢在森林里漫步。在那一片深绿,或者油绿、墨绿、碧绿、黛绿、翠绿、嫩绿、豆绿、水绿赫然构成层次的山野,踏着灿烂的阳光,吸着清新的空气,嗅着馥郁的花香,迎着凉爽的山风,登上山巅,在湛蓝如洗的天空下,在呼啸而至的山风中,看万木吐翠,看万叶闪光,看万树起舞,仿佛海洋在翻腾一样,涌着无垠的绿涛横亘

浅谈苗圃的经营与管理

苗圃是培育苗木的基地,其经营的好坏影响到苗木的供给。随着林业生产迅猛发展,为苗木产业发展带来了机遇。如何提高苗圃生产水平,以适应林业发展和林业现代化的需要,已成为当务之急。文章通过阐述影响苗圃生产的因素,苗圃如何合理规划,提出苗圃生产经营的管理要点,为行业工作者提供一定的理论参考。     

The operational planting stock quality testing program at Weyerhaeuser

The value of the Seedling Testing System (STS) is five-fold. First, it minimizes the utilization of poor quality stock that might result in regeneration failure. Second, it assists nursery managers in estimating cold hardiness of seedlings in support of the nursery frost control program. Third, it helps prevent crop losses due to pathological problems in the greenhouse and nursery. Fourth, it helps the nursery staff develop good working relationships with outside customers who benefit from the testing service. Fifth, it is a valuable tool for the nursery and tree improvement research program.     

Genetic bottlenecks in agroforestry systems: results of tree nursery surveys in East Africa

Seedlings sourced through tree nurseries are expected to form an important component of future tree cover on farms. As such, the genetic composition of nursery seedlings is expected to impact on the productivity and sustainability of agroforestry ecosystems. By surveying current practices of nursery managers in five areas from Kenya, Tanzania and Uganda, we quantified parameters associated with the collection, production and distribution of tree germplasm in East Africa. Considerable variation for seed-propagated nursery species was observed in the number of maternal parents (mother trees) sampled to establish nursery lots, the quantity of seedlings raised in nursery lots and the projected number of clients for nursery lots. Current seed collection practice was the most obvious limiting bottleneck in delivering high levels of genetic diversity to farmers. In the 143 cases analysed, seed to establish nursery lots was collected from a mean of only 6.4 maternal parents. In 22% of cases, ursery lots were established from a single maternal parent. On average, each maternal parent produced sufficient progeny to provide all the seedlings received by an individual nursery client. Consequently, the potential impact on farm and landscape genetic diversity of possible non-randomisation of progeny within nurseries is serious. In two instances, pair-wise analysis of transformed data suggested significant differences between geographic areas in the projected number of clients for nursery lots. We discuss improved nursery practices likely to promote genetic diversity, in particular increased maternal parent sampling and germplasm exchange.

Operational Effectiveness of Centralized Nursery for Small-Scale Forestry in San Carlos City, Negros Occidental, the Philippines: Lessons Learned in Seedling Production for Commercial Energy Crop Plantations

One way to maximize potential income of smallholder tree farmers is to ensure high quality of planting material. In San Carlos City, Negros Occidental, the Philippines, great importance is placed on seedling quality because Energy Crop Plantations (ECPs) managed under a Short-Rotation Coppice (SRC) system will involve a single planting for several three-year coppices. High seedling quality requires superior seed provenances and seedling propagation methods. Throughout the establishment of the nursery facility, and the propagation of planting stock, data collection, reporting and database systems have been designed to capture relevant costs and technical information. Training has been provided to nursery personnel and labourers to enable them to operate the nursery and produce high quality seedlings. This paper reports a practical operational evaluation of all materials and procedures followed in nursery establishment and seedling production. Economies of scale in nursery operation are achieved at a production level of at least 90,000 seedlings per planting season of three months in the year. The production cost is estimated at PhP 3.57/seedling, excluding the cost of the nursery infrastructure and overheads. Cost comparison with decentralized or contracted nurseries shows little variation at a total cost of PhP 4.12/seedling. However, with these alternative nursery arrangements there is high risk of producing low quality seedlings by possible reduction of inputs and skipping quality enhancement procedures to reduce production cost.
