粮食专用型ＢＲ－１２０８０００倍水溶液分蘖期和灌浆期喷施，明显促进试验中各组配套技术对旱地小麦的增产效果；其作用主要表现在增加千粒重；其次是增加穗粒数．在每ｈｍ２施用细厩肥１５０００ｋｇ作盖种肥＋硫酸钾６０ｋｇ／ｈｍ２作种肥或生物钾肥７５ｋｇ／ｈｍ２拌种的条件下，喷施ＢＲ－１２０的增产效果最好
Spraying at the tillering and filling stages of food-specific BR-1208000 water solution obviously promoted the increase of yield of dry land wheat by the matching technology of each group in the experiment. The main function was to increase 1000-grain weight, followed by increasing the number of grains per spike. Under the condition of dressing 15000kg of fine manure per hm2 for cover fertilizer and 60kg / hm2 of potassium sulfate for seed dressing or 75kg / hm2 for biological potassium fertilizer, spraying BR-120 had the best yield increase effect
