【Abstract】 Potatoes were used as the experimental materials to study the characteristics of Wendegao 301 and its application to the dry land crop of Hunan in 2001.The results show that the crop treated with 900 kg/hm 2 Wendegao 301 increases the output by 6.21% in comparison with that treated with 750 kg/hm 2 Danmark complex fertilizer plus 750 kg/hm 2 phosphorous fertilizer, both of which are of the same cost. It increases the output by 11.58% as compared with that without fertilizers.Wendegao 301 supplies a relatively low rate of nitrogen at the seedling stage, which suggests that small amount of N fertilizer should be used to make full use of Wendegao 301’s nutritional effect.更多还原
