玉米联合固氮菌剂是河北省科学院近年来研制成功的新型生物制剂。该菌剂除能与玉米根系相结合,固定大气中分子态氮,改善玉米氮素营养外,还能产生植物生长调节物质,促进玉米生长发育,并能活化土壤中的磷、钾元素,改善玉米的营养状况,从而提高玉米产量。为了探索该菌剂在新疆自然气候、土壤条件下,在玉米上的增产效果与使用技术,我们于1989—1990年进行了试验、示范。协作单位9个,示范点23个。现将试验、示范结果初报如下:
The combination of azotobacter corn is a new type of biological preparation successfully developed by Hebei Academy of Science in recent years. In addition to being able to combine with corn root system, fixing the molecular nitrogen in the atmosphere and improving the nitrogen nutrition of corn, the fungicide can also produce plant growth regulating substances, promote the growth and development of maize, and activate phosphorus and potassium elements in the soil to improve Corn nutritional status, thereby increasing corn production. In order to explore the bacterial agent in Xinjiang natural climate, soil conditions, the effect of corn on the yield and use of technology, we conducted experiments in 1989-1990, demonstration. 9 cooperation units, 23 demonstration sites. The trial and demonstration results are as follows:
