试验表明 ,用 30 0 ml/hm2 “绿灵宝”复合植物营养液对水 150 kg拌种 ,能促进大麦的生长发育 ,冬前总苗数、成穗数、千粒重等有明显提高 ,成熟期提早 3～ 5d。用 150 0 ml/hm2 “绿灵宝”对水750 kg,分别在大麦孕穗期、灌浆初期叶面喷施 ,能促进籽粒灌浆充实 ,大麦的穗实粒增加 0 .3～ 0 .6个 ,千粒重增加 0 .3～ 0 .8g。用“绿灵宝”既拌种又叶面喷施的效果最好 ,大麦单产 4 331.0 kg/hm2 ,比喷施“活力素”的常规对照增产 4 55.4 kg,纯收益增加 354.0 0元 /hm2 。

The results showed that the treatment of 150 kg of seedling with 30 0 ml / hm2 “Lvbao” compound plant nutrient solution could promote the growth and development of barley. The total seedling number, Early 3 ~ 5d. Spraying 750 kg of water at 150 0 ml / hm2 “Lv Lingbao” on the foliage at the booting stage of barley and the early filling stage, respectively, could promote grain filling and enrichment. The spikelet number of barley increased 0.3 ~ 0.6, Thousand grain weight increase 0 .3 ~ 0 .8 g. The results showed that “Green Lingbao” had the best effect on both seed dressing and foliar spraying. The yield of barley was 4 331.0 kg / hm2, increased by 4 55.4 kg compared with the conventional control spraying “vitamins”, and the net income increased by 354.0 0 yuan / hm2 .
