通过2009～2010年在湖南水稻、大麦、小麦、玉米和高粱等几种主要粮食作物上应用万春钛微肥试验,初步肯定了含钛微肥在这些作物上叶面喷施的效果,结果表明:(1)水稻喷施钛微肥每穗总粒数和实粒数比喷自配微肥的处理分别增加3.0%和3.8%,增产150 kg/hm2左右,平均增产7.4%;(2)几种叶面调控剂比较,以含钛微肥增产效果最明显,增产645.4 kg/hm2,增幅37.0%,其次为多效唑,增产424.9 kg/hm2,增幅24.4%,其它产品增产效果不明显;(3)小麦喷施万春钛微肥较喷自配微肥后期成穗率提高5.1%,穗粒数增加3.4%,千粒重增加1.6%,增产235.5 kg/hm2,增幅11.1%;(4)高粱喷万春钛微肥处理地上部干物质总量较喷自配微肥处理增加4.6%～13.7%,平均增加10.8%,籽粒产量也明显增加3.9%～7.9%(平均6.0%)。
Through the application of Wanchun Titanium Fertilizer Experiment on several main grain crops such as rice, barley, wheat, corn and sorghum in Hunan from 2009 to 2010, the effect of foliar application of titanium-containing fertilizer on these crops has been tentatively confirmed. Results The results showed that: (1) The total grain number and the number of solid grains per spike were increased by 3.0% and 3.8% respectively, and the yield was increased by about 150 kg / hm2 with an average increase of 7.4% Compared with several foliar control agents, the yield increase effect of the titanium-containing micro-fertilizer was the most obvious, with an increase of 645.4 kg / hm2, an increase of 37.0%, followed by paclobutrazol with an increase of 424.9 kg / hm2, an increase of 24.4% (3) The percentage of spikelets per spike increased by 5.1%, the number of grains per spike increased by 3.4%, the grain weight per thousand increased by 1.6%, and the yield increased by 235.5 kg / hm2 by 11.1%; (4) Sorghum spurt The total dry matter content of Wanchun titanium treated shoots increased 4.6% ~ 13.7% compared with spraying self-fertilizing micronutrients, with an average increase of 10.8% and grain yield increased by 3.9% ~ 7.9% (average 6.0%).
