摘要： 1980～1997年改良退化草原4349.2km2,主要改良措施:1浅耕翻改良,有效利用15年,年均增产90.5%。2松土改良,有效利用年限6～10年,平均增产70.35%。3施肥改良,其中施尿素187.5kg/hm2,产草量提高3.2倍,施厩肥30～37.5t/hm2,第二年增产53.5%。4引种国内外苜蓿品种25个,筛选出一批耐寒抗病品种,每年割两茬,干草产量4927.5kg/hm2,是对照的3倍。表现好的品种有黄花苜蓿、肇东苜蓿、公农1号苜蓿、公农2号苜蓿、草原2号苜蓿。5补播改良效果不佳。

Abstract: From 1980 to 1997, an experiment of improving deteriorated rangeland was carried out. The approaches adopted and their effects are as follows: ①Grassland improved by shallow ploughing its effect lasted 15 years. The average annual herbage yield increased by 90.50%. ②Grassland improved by deep loosening. Its effect lsated 6～10 years. The average annual herbage yield increased by 70.3%. ③Grassland improved by appling fertilizer 187.5 kg of urea was used per ha. The annual harbage yield increased by 3.2 times. If 30～37.5 t of manure is applied per ha, the herbage yield of the following year can be increased by 53.5%. ④Use of the selected fine varieties of alfalfa, sone coldness and disease resistand varielies were selected and grown. Each year 2 harvests can be reaped. Its annual herbage yield equals 3 times. The yield of the local variety. ⑤The effect of interseeding is not good.
