Establishment of laborsaving cultivation system in pear orchard: (2) Production of organic materials in pear orchard and selection of excellent kind of grass from the standpoint of management

ナシ園における省力化栽培体系の確立 (2)ナシ園における有機物生産および管理面から見た優良草種の選択
Study period:2001 - 2003
Research overview:
Sod culture including weed sod culture, in which organic materials are self-supplied in orchards, has recently been popularized to a significant extent, because rice straw and the like have become difficult to obtain and it is effective for the prevention of disease infection. However, sod culture based on sowed pasture grasses is little practiced and it is mostly weed sod culture. Grasses that are resistance to shading and tread pressure, need few weedings during summer, and are not hosts parasitized by mites were selected. Because grass yield was equivalent to that of Italian ryegrass, which had already been considered suitable, and labor was saved with few weedings in a plot where vulpia was sown, vulpia was selected as a grass species for sod culture in Japanese pear orchards. The shortfalls of vulpia were the following : local weed occurrence depending on the direction of grass lodging, adherence of its stimulating seeds onto socks, and the difficulty to remove them.
