Effects of fertilization amount on growth and yield of winter wheat
To investigate the effect of fertilization amount on the growth,development,and yield of winter wheat,2 winter wheat varieties,Zangdong 20 and Shandong 7 were used as materials,and low fertilizer,medium fertilizer,and high fertilizer treatments were set to explore their effects on this plant phenological period,agronomic traits,and yield,to explore the optimal fertilizer application rate.The results showed that under different fertilization treatments,the full growth period of 2 winter wheat varieties was 264-281 days,with the medium fertilizer treatment having the longest full growth period.Under different fertilization treatments,both winter wheat varieties showed better agronomic traits in terms of plant height,stem diameter,and stem node length under the ear when treated with medium fertilizer.In terms of yield and yield composition,the basic number of seedlings,total number of tillers,fertile spikelets,number of grains per spike,single spike grain weight,single plant grain weight,and yield were higher in the medium fertilizer treatment,while the sterile spikelets were lower,and the highest yield of Zangdong 20 was higher than that of Shandong 7.The medium fertilizer treatment is beneficial for wheat growth and has a higher efficiency in absorbing and utilizing fertilizers.Overall,medium fertilizer treatment can effectively extend the wheat jointing stage to heading stage,allowing it to absorb and accumulate more nutrients,and the agronomic traits showed better performance,with a significant increase in yield.The high-efficiency planting model of winter wheat Zangdong 20+medium fertilizer level can be adopted.
