微生物肥料在小麦上的施用效果初步研究

Preliminary Study＇ on Effect of Application of Microbial Fertilizer to Wheat

本试验以小麦为试验材料，研究微生物肥料对小麦的增产增收效用。试验结果表明：施用生物有机肥＋微生物菌肥和单施生物有机肥、单施微生物菌肥比对照分别增产444．0、435．0、409．0kg／hm2；增产率分别为13．5％、13．2％、12．4％；产出分别净增收入115．20、205．50、369．70元／hm2；施用生物有机肥＋微生物菌肥和单施生物有机肥、单施微生物菌肥产投比分别为1．25、1．57、3．28。可得出结论：在北京地区施用微生物肥料可促进小麦的田间生长，提高返青，增强不同生育期的抗性，后期落黄性较好，成熟均匀一致，在一定程度上增加了小麦的株高、穗长和叶绿素含量，提高了小麦的有效分蘖数，对籽粒灌浆也有良好的促进作用，千粒质量也在一定程度上有所提高。

The experiment was focused on studying microbial fertilizer on wheat yield and income effectwith wheat as experimental materials. The experimental could conclude that application of microbial fertilizer could promote the growth of wheat field, improving greening, enhances resistance at different growth stages, later yellowing, mature uniform, to some extent increase the plant height of wheat ear length and chlorophyll contont, increased wheat effective tiller number, grain filling on also has a good role in promoting, l 000-grain weight and improved to a certain degree in the Beijing region. The experimental results showed that using biological organic fertilizer, microbial fertilizer and the single application of biological organic fertilizer, the single application of microbial fertilizer respectively by 444.0, 435.0, 409.0 kg/hm2; production rate is respectively 13.5%, 13.2%, 12.4% respectively, the output of nell income 115.20 yuan/hm2, 205.50 yuan/hm2, 369.70 yuan/hm2, application of biological organic fertilizer ＋ microbial fertilizer and the single application of biological organic fertilizer, the single application of microbial fertilizer ratio were 1.25, 1.57, 3.28 in this test.
