Abstract

Cuttings are taken from high-yielding, select stock, in special sizes. The mature shoots of the first year's growth in the nursery are cut back, providing further cuttings, and cut-back plants are grown on for another two years before planting out. In the Danube flood-plain such plants are 6-7 m....

Abstract

Economic Poplar stands of the State forests in the Danube flood-plain cover 3522 ha. Working-plan reports give, for the average site class, a rotation of 40 years for the highest value increment. Stand improvement by thinning is economic so long as the volume of principal fellings is encroached...

Abstract

Among controlling factors, the forester's most Potent influence is through manipulation of stem number. close- and open-stocking regimes of PopulusXmarilandica are compared in detail. of thinnings are growing stands. regulation of stem objects of management are advocated. KEYWORDS: Entomology \...

Abstract

cf. F.A. 16 No. 3000.] In support of his former contention, based on Poplar yield-table work, that by early selection of a few well spaced stems, specially tended, a given d.b.h. can be got in a considerably shorter rotation, the author now instances stand data for Populus X marilandica on site...

Abstract

The annual requirement of Populus tremula seed in Hungary, is ca. 1800 kg. Suitable apparatus of the forced-draught, warm-air type [Cf. F.A. 22 No. 2993] has now been tested for cleaning and drying this seed. Nearly 50% more seed was obtained than by hand rubbing. On account of the temperature used ...

Abstract

Fertilizing is economic, according to the author's studies, only on sites with a good water economy, but especially in Poplar stands. The simultaneous use of mineral and green manures in humus-deficient soils and, on very acid and compacted soils, of lime in addition, is very advantageous. Normal...

Abstract

Describes a deep ploughing method in which plants ca. 100 cm. high are set against an 80-cm. plough slice and covered (to a depth of 80 cm.) by the next slice, at half the cost of pit planting. This has proved successful for Poplars and Robinia (root systems shown); Pines are under trial. KEYWORDS: ...

Abstract

Contains tabulated statistics of area and yield by species and their values. Ca. 1/2 of the forest area is suitable for Poplars; these provide the greatest volume and value yields, which could be still further increased. Improvements in Willow cultivation lie in breeding, the abolition of the...
