如何依据不同小麦品种的特点科学施肥,充分发挥品种长处,用少量肥料获得更多的产量,是一项重要的研究內容。1978年我们选择了内蒙三号、京红九号、089、叶考拉、白欧柔、红芒、卡捷姆等七个春小麦品种进行了试验研究。试验地土壤肥力中上等,速测结果:土壤NO_3—N在20ppm以上,有效性p_2o_5在40ppm以上,有效性氧化钾在300ppm以上。秋施有机肥3000斤/亩,生育期间分蘗期追施尿素20斤/亩,拔节期追施 How to fertilize according to the characteristics of different wheat varieties, give full play to the strengths of varieties and obtain more yields with a small amount of fertilizer is an important research content. In 1978, we selected seven spring wheat varieties, Inner Mongolia No.3, Jinghong No.9, 089, Ye Koala, Baiou Rou, Hongmang and Kartems. Soil fertility test in the best, quick test results: Soil NO_3-N 20ppm or more, the effectiveness of p_2o_5 40ppm or more, the effectiveness of potassium oxide 300ppm or more. Autumn organic fertilizer 3000 kg / mu, during the tillering stage topdressing urea 20 kg / mu, jointing stage
