GPIT生物制剂在不同年代育成、不同粳糯性类型、不同经济系数的3个黍稷育成种上的应用试验表明，在其高光效的前提下，强化了3个黍稷育成种的生理代谢，平衡了营养生长和生殖生长的能力，使经济系数均得到了提升。但提升的幅度均有差异，对自身经济系数原本就低的，并且育成年代短的、粳性类型的品糜1号经济系数提升的幅度最大；对育成年代居中的、糯性类型的、自身经济系数原本就较低的晋黍7号，经济系数提升的幅度也居中；对育成年代较长的、糯性类型的，且自身经济系数原本就较高的晋黍2号，经济系数提升的幅度是最低的。这个试验结果不仅对黍稷生产在应用GPIT生物制剂的实践中具有参考应用价值，对其它作物也同样具有参考价值。
The application tests of GPIT biological agents on three millet varieties grown in different ages, dif-ferent japonica glutinous types and different economic coefficients showed that on the premise of the high photosynthetic efficiency, strengthening the three proso millet breeding of physiological metabolism, balancing the ability of vegetative growth and reproductive growth, and promoting economic coefficient are obtained. However, there are differences in the extent of improvement. The economic coefficient of Pingmi No. 1, which has a low economic coefficient and is of a short age and japonica type, has the greatest improvement. The growth age of the middle, glutinous type, their own economic coefficient is lower Jinshu 7; the extent of economic coefficient improvement is also in the middle. The growth of a longer age, waxy type, and its own economic coefficient of the higher Jin Millet 2, the extent of economic coefficient of improvement is the lowest. The experimental results are of reference value not only for proso millet production in the application of GPIT biologic preparation, but also for other crops.
