为探究氮肥缓释剂和硅肥对玉米产量的影响,选择德美亚3为试验材料,在常规施肥基础上,设置5个处理,分别为ck:氮来福0 kg/hm2、硅肥0 kg/hm2;N1:氮来福30 kg/hm2、硅肥0 kg/hm2,基肥尿素减量20%;N2:氮来福30 kg/hm2、硅肥 0 kg/hm2;Sia:氮来福 0 kg/hm2、硅肥 A 150 kg/hm2;Sib:氮来福 0 kg/hm2、硅肥 B 150 kg/hm2;分析其形态指标、产量指标、茎秆强度的变化规律.结果表明,与ck相比,N1、N2、Sia、Sib处理下,玉米茎粗分别提高了4.00%、2.70%、3.39%、3.22%;抗推力强度分别提高了2.12%、1.00%、9.34%、10.21%;行粒数分别提高了2.86%、2.68%、0.89%、4.11%;产量分别提高了5.92%、5.38%、1.69%、2.73%.硅肥Sia、Sib处理下玉米穿刺强度分别提高了2.68%、10.41%.5个处理中,产量排序依次为N1>N2>Sib>Sia>ck;穿刺强度排序依次为Sib>Sia>ck>N1>N2;抗推力强度排序依次为Sib>Sia>N1>N2>ck.
Effelts of Stem Strength and Yield between Urease Inhibitor and Silicon Fertilizer of Maize
In order to expore the effects of urease Inhibitor and silicon fertilizer of maize.Demeya 3 was select-ed as the test material,five treatments were set up on the basis of conventional fertilization,which was ck(Danlaifu 0 kg/hm2;silicon fertilizer 0 kg/hm2),N1(Danlaifu 30 kg/hm2;silicon fertilizer 0 kg/hm2;Urea reduction of base fertilizer by 20%),N2(Danlaifu 30 kg/hm2;silicon fertilizer 0 kg/hm2),Sia(Danlaifu 0 kg/hm2;silicon fertilizer A 150 kg/hm2),Sib(Danlaifu 0 kg/hm2;silicon fertilizer B 150 kg/hm2),and the morphological index,yield index and stem strength were analyzed.The results showed that,compared with ck,stem diameter of corn under N1,N2,Sia and Sib treatments increased by 4.00%,2.70%,3.39%and 3.22%.The thrust strength was increased by 2.12%,1.00%,9.34%and 10.21%.Row grain number increased by 2.86%,2.68%,0.89%,4.11%.The yield increased by 5.92%,5.38%,1.69%and 2.73%.Under the treatment of Sia and Sib,the puncture strength of maize increased by 2.68%and 10.41%.Among the 5 treatments,the yield was ranked from high to low as N1>N2>Sib>Sia>ck.The order of puncture intensity from high to low was Sib>Sia>ck>N1>N2.The order of thrust resistance from high to low was Sib>Sia>N1>N2>ck.
