2001年在内蒙乌兰浩特(试验1)、吉林省公主岭(试验2)、辽宁昌图县(试验3)进行了环保型大豆重迎茬专用肥的田间试验,结果表明该专用肥配方1～6对“火龙秧子”有明显的抑制作用,各配方的产量均明显高于无肥对照和传统施肥二铵,除配方5处理外,差异均达到了显著水平。试验2和3的结果也表明,与无肥对照和传统施肥相比,该专用肥在大豆的生物学性状以及产量方面均表现明显优势,配方1和配方6的增产幅度分别达到了显著水平。但在这三个试验中增产幅度有较大差异,试验1和3(孢囊线虫重度和中度),大豆产量的增产幅度为1.48倍～9.4倍,优于药肥1大龙和药肥2的增产效果(1.11倍到7.0倍),试验2(轻度发病)各配方增产幅度为2.3%～15.9%,其中有几个配方的效果好于药肥1大龙和药肥2。另外环保型大豆重迎茬专用肥提高了大豆籽粒中粗脂肪含量。
In 2001, field experiments were conducted in Wulanhaote, Inner Mongolia (Experiment 1), Gongzhuling (Experiment 2) in Jilin Province and Changtu County in Liaoning (Experiment 3). The results showed that the special fertilizer formula was 1 ~ 6 pairs “Fire dragon seedlings” have obvious inhibitory effect, the yield of each formula were significantly higher than the no fertilizer control and traditional fertilization of diammonium, except for the formula 5 treatment, the differences have reached a significant level. The results of experiments 2 and 3 also showed that compared with no fertilizer control and traditional fertilization, the special fertilizer showed obvious advantages in biological characters and yield of soybean, and the yield of formula 1 and formula 6 reached significant levels respectively. However, the rate of increase in these three experiments is quite different. In tests 1 and 3 (severe and moderate cyst nematode), the yield increase of soybean yield was 1.48 times to 9.4 times, which was better than that of 1 large dragon and drug fertilizer 2 (1.11-fold to 7.0-fold). In trial 2 (mild incidence), the yield of each formula ranged from 2.3% to 15.9%. The effect of several formulations was better than that of 1D and 2D. In addition, the environment-friendly soybean replanting special fertilizer to improve the crude fat content of soybean grain.
