Experiment on the input-output ratio of late-sowing and weak wheat seedling in Puyang City
摘要
Abstract
Since July 2021,Puyang City has been affected by multiple rounds of heavy rainfall and other factors,resulting in a general delay of about 15 days in wheat sowing.Late-sowing wheat accounts for a large proportion of the area.Through investigation and analysis of tillering,population,yield,and input-output ratio of late-sowing wheat in Wusizhuang Village,Fanxian County,Puyang City,this study explores remedial measures suitable for promoting weak seedling wheat growth in Puyang City,and identifies economically reasonable nitrogen fertilizer application rates to balance agricultural input costs and actual output.Therefore,a late sowing wheat input-output ratio experiment was conducted in Puyang City.The experimental results showed that late sowing had a significant impact on the number of spikes,number of grains per spike,1 000 grain weight,and yield of wheat.In practical production,late sowing should be avoided as much as possible.In case of human uncontrollable factors causing late sowing,187.5-247.5 kg·hm-2 urea and 75 kg·hm-2 diammonium phosphate can be applied during the greening period,and 307.5 kg·hm-2 urea can be applied during the jointing period to increase the number of spikes,number of grains per spike,and 1 000 grain weight of late-sowing weak wheat seedling,thereby improving wheat yield and increasing income.关键词
