为明确植物生长营养液对燕麦生长及产量的影响,研究了燕麦拔节期、抽穗期和灌浆期喷施相同量不同稀释倍数的植物营养液后燕麦株高、干物质积累量、产量及产量构成因素的变化。结果表明:不同稀释倍数的营养液均可以缩短燕麦生育期,其中500倍稀释液与对照相比可提前7d成熟;各营养液处理的燕麦株高、干物质积累量和叶面积在抽穗期、灌浆期和成熟期均高于对照,各指标均随着稀释倍数的增加先升高后降低;喷施植物营养液后燕麦穗数、穗粒数、千粒重和产量均增加,喷施500倍稀释液后,燕麦穗数、生物产量和子粒产量与其他处理间差异均达显著水平,子粒增产达15.9%。
In order to clarify the effects of plant growth nutrient solution on the growth and yield of oats, the plant height, dry matter accumulation, yield and yield components of oat after spraying the same amount of plant nutrient solution at jointing, heading and filling stages were studied Changes in factors. The results showed that: different dilutions of nutrient solution can shorten the oat growth period, of which 500-fold dilution compared with the control 7d early maturity; nutrient solution-treated oat plant height, dry matter accumulation and leaf area at heading, The grain filling rate and grain filling rate were all higher than those of the control at the filling stage and the maturing stage. The indexes increased at first and then decreased with the increase of dilution times. After sprinkling the plant nutrient solution, the number of spikes, grains per spike, After the treatment, the differences of spike number, biomass and grain yield between oats and other treatments reached significant levels, and the grain yield increased by 15.9%.
