不同播种方式和播深对宁夏引黄灌区滴灌春小麦生长及产量的影响
The Effect of Different Sowing Methods and Depths on the Growth and Grain Yield of Spring Wheat Under Drip Irrigation in the Yellow River Irrigation Area of Ningxia
摘要
Abstract
In order to improve the sowing quality and grain yield of spring wheat under dry sowing and wet emergence patterns in the Yellow River irrigation area of Ningxia,a spring wheat variety Ningchun 58 was used as the experimental material in this study,the indexes such as wheat growth period,stem characteristics,grain yield,and yield components in four treatments including sowing depth 3 cm(control,CK),and 6 cm(TS)by stripe manner,and 3 cm(YQ)and 6 cm(YS)by uniform manner were investigated to explore the optimal sowing method for dry sowing and wet emergence planting technology of wheat in the region.The results showed that uniform sowing occurred earlier than strip sowing during the emergence period of spring wheat,but strip sowing occurred earlier than uniform sowing during the maturity period;and the number of harvested spikes in uniform sowing increased 38×104 spikes/ha compared to stripe sowing,the stem thickness and stem strength of the second internode in uniform sowing was higher than those in stripe sowing,and the average grain number per spike,one thousand grain weight,and grain yield in uniform sowing were increased by 1 grain,0.6 g,and 341.25 kg/ha,respectively,in comparison with stripe sowing.In the same sowing method,sowing depth 6 cm delayed emergence time,increased the average stem length of the second internode by 0.96 cm,and reduced the number of harvested spikes by 105×104 spikes/ha,grain number per spike by 4 grains,and yield by 1 664.25 kg/ha compared to sowing depth 3 cm.The treatment of the sowing depth 3 cm in uniform sowing resulted in the highest number of harvested spikes,grain number per spike,and one thousand grain weight,with a yield increase of 7.6%-19.8%compared to other treatments.In conclusion,the optimal sowing method for dry sowing and wet emergence technology of wheat in the Yellow River irrigation area was the sowing depth 3 cm in uniform sowing.关键词
