Abstract


Feed shelterbelt construction, as an important part of the ecological economy of western Liaoning Province forestry construction, improve the ecological environment and increase economic benefits, effective measures to improve social benefits. Therefore, in order to obtain a good feed shelterbelts, cropping patterns, cultivation, operation and management of technology screening is particularly important. And improving the results of the physical and chemical properties of the feed shelterbelts growth climate and soil of western Liaoning Province the microphylla child (Caragana microphylla) the microphylla children feed shelterbelt plants growth dynamics, biomass dynamics and changes in crude protein dynamics explore and summarize the main conclusions: (1) the microphylla children feed shelterbelts temperature changes: the flat-lying forest belt of ground temperature and the air temperature is lower than the temperature of the open land; mountain forest belt air temperature is higher than the air temperature of the open land; Mountain shady slope forest belt of ground temperature is lower than the air temperature. (2) the microphylla children feed shelterbelts humidity changes: forest belt of ground humidity and air humidity are higher than the humidity of the open land; mountain shady slope forest belt the ground humidity is higher than the open space humidity. (3) not deciduous, flat stubble the microphylla children feed shelterbelts wind effect; deciduous, not stubble the microphylla children feed shelterbelts wind effect. (4) mountain grass intercropping mode best soil improvement, soil bulk density smaller soil silt proportion increases, enhanced water retention, increased soil organic content; plains soil improvement effect: forest - grass mode gt; Lin - Economic Crop mode gt; the forest - crop mode; microphylla children nitrogenase effect generally affect the range of 1 times the tree height distance from the undergrowth. (5) children microphylla high growth and diameter growth rate: Lin - Economic Crop mode gt; the Lin - grass Mode gt; forest - crop Mode; mountain shady slope plants gt; the ground Plants gt; plants of mountainous sunny slope; Stump 2 years old plants gt; not stubble 5 years old plants gt; stubble 1 year old plants. Microphylla year children high in July and August, the fastest growth, the fastest growing diameter within 5-6 months. (6) lobular microphylla children aboveground biomass size: total biomass change forest - grass mode gt; Lin - economic crop mode gt; forest - crop mode, not flat stubble five years students plant gt; stubble 2-year old plants gt; flat stubble one year old plants, biomass, density Sept. 60 / plexus can obtain high biomass. Edible biomass: Stump 2-year old plants gt; the not flat stubble five years old plants gt; 1 year old plants stubble. (7) the lobular the golden pheasant children edible part of total histone reached a peak in June. The edible part of the total amount of crude protein comparison: Mountain the sunny slopes Plants gt; plains plants gt; Mountain shady slope plants; Stump 2-year old plants gt; not stubble 5 years old plants gt; stubble 1 year old plants. (8) is drawn through the experimental study: the best western Liaoning Province the microphylla children feed shelterbelts cultivation site conditions is mountainous sunny slope; optimal cropping patterns forest - grass mode, if the feed value less demanding, the pursuit of greater economic benefits using the Lin - Economic crops mode; planting density of 60 / cluster; optimal line spacing of 5m; the flat stubble interval of years to 2 years; want to get the maximum harvest harvest in September, to get the maximum feed production in six Month harvest.
