劲丰谷德对淮稻18的抗倒伏性和产量的影响

The Anti-lodging and Yield Increase Effect of Jinfenggude on Huaidao 18

以水稻品种淮稻18为试验材料,研究了增产抗倒剂劲丰谷德对其株高、节间长度、节间充实度、抗折力及产量等性状的影响。结果表明:1)通过缩短淮稻18倒1节和倒2节长度,可降低植株重心,增加植株各节间的茎粗和茎秆的壁厚,从而使得在破口期劲丰谷德具有显著的抗倒效果。2)通过增加穗实粒数与千粒重,可提高产量,增产达226.5kg·hm-2,增产率为2.37%。由此说明在淮稻18上喷施劲丰谷德不仅能增强抗倒性,还能提高水稻产量,达到增产与抗倒的有机统一。

In this paper,the effects of rice variety Huaidao 18 on plant height,Internode length,Internode fullness,folding resistance and yield characters were studied.The results showed that,by shortening the length of 18 Huaidao 18 1 inverted nodes and 2 nodes,reducing the center of gravity,increasing the stem diameter and the wall thickness of stem,Jinfenggude had significant anti-lodging effect during the break period.At the same time,the yield was increased by increasing the number of grains per ear and 1000-grain weight,and the yield was increased by 226.5 kg·hm^-2.The yield increase rate was 2.37%.Spraying Jinfenggude on Huaidao 18 can not only enhance the resistance to collapse,but also increase the yield of rice,and achieve the organic unity of increasing yield and resistance to collapse.
