BR-120对地麦配套技术增产效果的影响

Effect of Homobrassinolide on Increasing Yield of Cultural Practices System on Upland Wheat

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。

Aqueous solution(0.00625mg/kg) of Homobrassinolide improved the increasing yield’s effect of cultural practices system on upland wheat when it was applied at tillering and filing stage,respectively;it increased thousand-grain weight and grain number each ear. It showed best yield to spray Homobrassinolide with applying 15000kg/hm 2 compost with fine particle size as covering seed manure+60kg/hm 2 K 2 SO 4 as seed manure or 7.5kg/hm 2 potassium biofertilizer mixed with seeds.
