种植密度和播期对强筋小麦'新麦58'农艺性状及产量的影响
Effects of Planting Density and Sowing Date on Yield and Agronomic Characteristics of Strong Gluten Wheat Variety'Xinmai 58'
摘要
Abstract
To screen the suitable sowing date and planting density combination for'Xinmai 58',a two factor split field experiment was conducted in the National Agricultural High Tech Zone Demonstration Park in Dancheng County,Henan Province from 2023 to 2024,with the sowing dates(October 17,October 25,November 1,November 8)being the main area and the sowing amounts(150 kg/hm2,187.5 kg/hm2,225 kg/hm2)being the sub area,to explore the effects of different sowing dates and planting densities on the growth stage,population at different stages,dry matter accumulation,plant height,yield,and yield of'Xinmai 58'.The results indicate that:as the sowing periodis postponed,all growth stages are delayed,but the growth period is shortened,and the impact of planting density on the growth period is relatively small.The impact of different sowing periods on the population at different stages is relatively small,and sowing amountis the main factor affecting the population.The effects of different treatments on dry matter weight and yield are inconsistent.Late sowing affects dry matter accumulation,but increasing sowing amount can compensate for the loss of yield.The main factor affecting the number of spikes is sowing amount,and sowing date has a significant impact on the number of grains per ear,thousand grain weight,and plant height.Different treatments and their interactions result in significant differences in yield.The suitable sowing period for'Xinmai 58'is from October 17th to 25th,with a suitable sowing amount of 187.5 kg/hm2.If the sowing period is too late,,increasing the sowing amount appropriately can improve the yield level.关键词
