Effects of Nano-silicon Fertilizer on the Lodging Resistance and Seed Yield of Oat
摘要
Abstract
This study aimed to explore the effects of nano-silicon fertilizer on lodging resistance and seed yield of oat,and to determine the reasonable application rate of nano-silicon fertilizer in oat seed production.By spraying nano-silicon fertilizer at concentrations of 0(CK),0.6(A1 treatment),0.9(A2 treatment),and 1.2 g/L(A3 treatment)on oat leaves during the tillering stage,this study investigated changes in oat growth and development,lodging resistance,seed yield,and related traits under different levels of silicon fertilizer.The results showed that nano-silicon fertilizer had a promoting effect on the growth,development,and seed yield of oats.In terms of vegetative growth,the plant heights of A1,A2,and A3 treatments were 7.74％,11.30％,and 7.94％higher than CK(P<0.05),respectively;the stem di-ameters of A1 and A2 treatments were 18.09％and 12.96％greater than CK,respectively(P<0.05);and the effective ti-ller numbers of A1 and A2 treatments were 30.44％and 20.65％higher than CK(P<0.05),respectively.In terms of seed yield-related traits,silicon fertilizer significantly improved panicle structure,with the main panicle length of A2 treat-ment increasing by 11.00％compared to CK(P<0.05);the main panicle spikelet numbers of A1 and A2 treatments were 20.03％and 18.51％higher than CK(P<0.05),respectively;the main panicle seed numbers of A1 and A2 treatments were 41.05％and 45.05％higher than CK(P<0.05),respectively;the secondary panicle seed number of A1 treatment was 30.43％higher than CK(P<0.05);the main panicle grain weight of A1 and A2 treatments were 29.54％and 36.71％higher than CK(P<0.05),respectively;and the secondary panicle grain weight of A1 and A2 treatments were 30.29％and 49.84％higher than CK(P<0.05),respectively.In terms of seed yield,nano-silicon fertilizer significantly increased seed yield,with the seed yields of A1,A2,and A3 treatments being 3 952.51,3 810.95,and 3 326.98 kg/hm2,respec-tively,and A1 and A2 treatments being 21.33％and 16.98％higher than CK(P<0.05),respectively;the 1 000-grain weight of seeds of A1,A2,and A3 treatments were 24.74％(P<0.05),13.22％(P>0.05),and 12.78％(P>0.05)higher than CK,respectively.Additionally,the application of silicon fertilizer significantly enhanced lodging resistance of oat,with the lodging resistance indices of A1,A2,and A3 treatments being 7.90％,27.63％,and 21.05％higher than CK(P<0.05),respectively.Overall,under the conditions of this experiment,foliar spraying of 0.6 g/L nano-silicon fertilizer was an ideal fertilization scheme for seed production of oat.关键词
