油菜硼肥肥效研究

Rape Pang the fat research of fertilizer efficiency

通过田间小区试验研究,旨在寻求简便且费省效宏的施硼方法,结果表明:硼肥不同施用方法的肥效是,浸种>基肥撤施>喷施>不施硼肥,它们分别比不施硼肥667m2增产7.62kg,3.30kg,2.40kg,增产率分别为10.8%,4.7%,3.4%; 硼肥浸种增产的主要原因是大幅度地增加每株结荚数而深刻影响产量;最经济有效的施硼方法是用0.1%的硼砂溶液浸种 5-6h.

Through field sub-district experiment research, it is simple and convenient to aim at quest, save effect Hong's just to use Pang method, show as a result: Pang fat difference uses the fertilizer efficiency of method is , soak kind ' base fertilizer scatters do not use Pang fertilizer, they part than do not use Pang fat 667m2 increases production 7. 62 kg, 3. 30 kg and 2. 40 kg, rate of growth is 10. 8%, 4. 7% and 3. 4%; respectively Pang the major reason that fertilizer soaks kind to increase production is substantially increase each knot pod several and deep influence output ; is most economic and effective method is with 0.1% Pang sand solution soaks 5-6h.
