The beach plum, Prunus maritima Marsh is native to the sandy North Atlantic coast, from Newfoundland to North Carolina. It can grow well without irrigation, even on low-nutrient sandy soils, saline land, old-field and coastal beach where many other plants cannot survive. It is fine rootstock to improve stress tolerance of cion. The fruits of beach plum can be made into delicious jams, jellies and wine. This paper is aimed to introduce beach plum to people, and hope it can become an important multipurpose crop in Chinese coastal beach in the future.

A composição e a distribuição da vegetação herbácea da Praia do Peró foram caracterizadas em três áreas com topografias e fisionomias distintas, pelo método de parcelas. As três áreas são ocupadas pela comunidade psamófila-reptante, visualmente dividida em duas regiões: frontal, com espécies estoloníferas e suculentas, e posterior, com predomínio de espécies graminóides. Foram amostradas 38 espécies, das quais Paspalum maritimum Trim, Ipomoea imperati (Vahl.) Griseb, Ipomoea pes-caprae (L.) Sweet, Sporobolus virginicus (L.) Kunth e Panicum racemosum (Beauv.) Spreng. alcançaram os maiores valores de importância (VI). A topografia do ambiente, intimamente relacionada com a dinâmica de ondas de maré e tempestades, com aporte de areia oriunda dos ventos e das marés e com a ação antrópica, não influencia a distribuição das espécies vegetais encontradas, sendo considerada apenas como um componente influente na paisagem, estabelecido em conjunto com a comunidade vegetal, sendo esta última fortemente determinada pela distância em que se encontra em relação ao mar.

This paper presents the results of the research carried out in the All-Russian Research Institute of Reclaimed Lands. It has been established that land improvement techniques increased the integral index of physical soil conditions from 0.41-0.60 to 0.80-0.86. The soil demonstrated a greater total number of microorganisms, as well as certain physiological groups such as actinomycetes, autochthonous and especially nitrogen-fixers; but the number of fungi and denitrifiers, as well as the fungi causing the Fusarium wilt of the plants, decreased.Average crops increase achieved with the help of deep reclaiming band tillage of drained gleyish soil to depth 50-60 cm was 9.0-24.1% in both wet and dry years. This land improvement technique effect lasts for two-three years or longer. The ridged plowing compared to the ordinary plowing raised the spring crops by 0.55-0.61 ton/ha (by 16.9-17.5%) without making any additional expenditures.

The relationship between vegetation and soil supporting the habitats in 4 new industrial cities were assessed. Five main habitats were distinguished from inner city toward outskirts: lawns, home gardens, public gardens, waste lands and desert outskirts. After application of Twinspan, 26 vegetation groups were identified in the 5 recognized habitats, demonstrating that some groups are chatracteristic of a certain city, e.g. Asphodelus aestivus - Deverra tortuosa - Thymelaea hirsuta group was confined to the desert habitat of Burg El-Arab city; Thymelaea hirsuta - Linaria albifrons and Atriplex halimus - Atriplex lindleyi subsp. inflata - Suaeda vermiculata - Typha domingensis groups were found in the waste lands of Burg El-Arab city; Conyza bonariensis - Cynodon dactylon - Sonchus oleraceus group in the home garden habitat of 10th Ranadan city; Cynodon dactylon group in the lawns of Burg El-Arab city; Bassia indica - Plantago major group in the public gardens of Burg El-Arab city; Oxalis corniculata - Plantago lagopus group in the public gardens of 10th Ramadan city; Sonchus oleraceus - Cynodon dactylon and Dactyloctenium aegyptium - Leptochloa fusca - Phragmites australis groups in the public gardens of 6th October city. Silt, clay, organic matter, carbonates and carbon contents showed significant diffrences among the 5 habitats.
