摘要
20 0 3～ 2 0 0 4年对“俄罗斯优良”沙棘嫩枝扦插育苗技术的几项关键技术进行了田间试验。试验表明 ,使用方塘水比深井水N、P、K含量分别提高 3 7倍、 1 3倍和 0 1倍。水温提高 6 0～ 11 2℃ ,苗木高度生长量增加 11cm。试验还表明 ,基质中加入牛粪和草炭 ,有机质含量提高 2～ 3倍 ,苗床土壤的温度提高 0 1～ 0 9℃ ,苗木高生长量提高 2～ 4cm。改变追肥肥料的配比与增加追肥次数 ,苗木的高生长量分别提高 4cm和 5cm。
The field tests were carried out from 2003 to 2004 for key treatments in the nursery of Russian seabuckthorn Variety.The contents of nitrogen, phosphorus potassium are 3 7, 1 3, 0 1 times higher respectively with ground water for irrigation than that with deep well water sources The water temperature has raised 6 0～11 2℃ for the utilization of ground water than deep well water, resulting a 11cm increased in seedling height and 0 01cm increased in diameter at the base The contents of organic matter in the nursery soil has increased 2～3 times after adding up cattle manure and humus in the medium, along with the growth height increased of 2～4cm The heights of seedlings increased 4cm and 5cm respectively through more fertilizatian in terms of mixture rate and quantity.
