摘要
模拟光合作用和光形态建成的光谱,研制了一种新的稀土植物生长灯。该灯由发射蓝光的Sr_(10)(PO_4)_6 Cl_2:Eu^(2+)和aBaO·6A1_2O_3:Eu^(2+)(0.80<a<1.30),发射红光的LiAl_5O_8:Fe^(3+)和CeMgAl_(11)O_(19):Mn^(2+),以及适量的CaWO_4:Pb^(2+)和(SrMg)_3(PO_4)_2:Sn^(2+)荧光粉,按一定量配比而成。对水稻花培、蔬菜、花卉等多种植物的试验证明,该灯具有促进植物生长和分化的作用。通过测定光合强度,比较了植物生长灯和普通荧光灯的差异。
This paper reports a new type of plant growth lamp containing rare earth phos-
phors. Its emission spectrum meets the need for energy conversion processes,
chlorophyl syntheses and photosynthesis of plants. The lamp is a low-pressure
mercury vapor fluorescent lamp with a coating, consisting of phosphors Sr_(10)(PO_4)_6
Cl_2:Eu^(2+), aBao. 6Al_2O_3:Eu^(2+), LiAl_5O_3:Fe^(3+), CeMgAl_(11)O_(19): Mn^(2+), CaWO_4: Pb^(2+)and
(MgSr)_3 (PO_4): Sn^(2+). It is inexpensive, with efficient emissions providing fixed
amounts of radiations in the orangered and blue-violet regions of the spectrum for
simultaneous irradiation. The radiations promote both growth and differentiation of
anther culture in rice, vegetables and flowers.
