JOURNAL FREE ACCESSZoysia grass were given the growth examination, varing with nitrogen fertilization amount, fructose application amount and mowing height.
Under the whole irradiate condition, two grams per 1/5000a Wagner pots of nitrogen fertilizing was sufficiency. But under the shade condition, this proper quantity was decreasing. This amount was one gram per 1/5000 a under twenty percent irradiation.
The effect of fructose application was unsolved.
Three centi-meters mowing height gave a good result under the whole irradiate condition. Under the shade condition, it was concluded that two centi-meters heigh was vest from the point of view of reproduction of zoysia grass.View full abstractDownload PDF (728K) -

JOURNAL FREE ACCESSWe investigated on succession of vegetation by a method of slope protection in South Alps forestry road (Ashiyasu-Yashagin path) . The summarized results of the investigation were as follows;
1. The vegetation by this slope protection method was kept in steeper slope than the vegetation by general methods.
2. The species of the vegetation were mainly seeding species such asDactyris glomorata, Festuca arundinacea, but native plants such asMiscanthus sinensis, Polygonum cuspidatumwere 10 percent in occurrence ratio. And then we can make that the succession of this vegetation progressed a little.
3. The vegetation cover ratio of under parts of a slope was better than upper parts of a slope, but there were more invader shrubs upper parts of a slope.
4. The occurrence ratio ofMiscanthus sinensis, Polygonum cuspidatumof the invader species had relation to the vegetation cover ratio of seeding species, but the occurrence ratio ofRubus crataegifolius, Lespedeza bicolorTurcz.var. japonicsdid not.View full abstractDownload PDF (971K) -

JOURNAL FREE ACCESS1. There are great changes of location about vegetation transition.
2. On the south slope take precedence White clover, Orchard grass and Kentucky blue grass, another one, on north slope are high rate of creeping red fescue.
3. Grass length extends from May till early in June and from the middle of August till early september. The cause think about growth optimum temperature 15-20°C for Cool season type.
4. The soil temperature carried away by light energy, south slope is high than north slope. In this fact shows change into something, illuminance and amount of solar.
5. You can rationally planning for green space management from hold of growth conditions, both sides of south and north slope.View full abstractDownload PDF (713K) -
