以威优 64为材料进行了杂交水稻施用微肥钼 (Mo)、锌 (Zn)两因素各 3水平的田间籽粒产量比较试验。结果是 :( 1 )威优 64对钼酸胺不敏感 ,各处理间籽粒产量无明显差异 ;( 2 )施 0 .75kg/667m2 硫酸锌作基肥 ,比空白ck籽粒产量增加 8.3 9%、比施 1 .50kg/667m2 的A3处理增加 5.4 6%;( 3 ) 0 .75kg/667m2 ,1 .50kg/667m2 硫酸锌作基肥分别使杂交稻威优 64穗粒数比ck增加 1 4.93 %,1 2 .1 9%,是籽粒产量增加的原因之一 ;( 4)硫酸锌用量多的A3( 1 .50kg/667m2 ) ,虽然穗粒数比ck增加 1 2 .1 9%,但籽粒产量与ck无明显差异 ,证明过量的锌反而抑制水稻个体生长发育与群体的合理调节。
In this experiment, we tested the grain yield of three hybrid rice lines (Weiyou 64) and micro-fertilizer molybdenum (Mo) and zinc (Zn). The results were as follows: (1) Weiyou 64 was insensitive to molybdate amine, and there was no significant difference in grain yield between treatments. (2) Applying 0.75kg / 667m2 zinc sulfate as basal fertilizer, the grain yield increased 8.39% (3) 0.75kg / 667m2, 1.50kg / 667m2 zinc sulfate as basal fertilizer increased the grain number of hybrid rice Weier 64 by 1 4.93% 1, 1 2.19%, which is one of the reasons for the increase of grain yield; (4) A3 (1.50kg / 667m2) with more zinc sulfate dosage, although the number of grains per spike increased by 12.19% ck no significant difference, to prove that excessive zinc instead inhibits the individual growth and development of rice and the population of a reasonable regulation.
