Effects of Chemical Fertilizer Reduction Combined with Organic Fertilizer on the Yield, Quality, and Water Use Efficiency of Dryland Wheat
The effects of combined application of organic fertilizer and chemical fertilizer on yield
quality
and water use efficiency of dryland wheat were studied
which provided theoretical basis for substituting chemical fertilizer with organic fertilizer and reducing annual yield fluctuation in dryland wheat field in loess hilly region. In 2017—2019
the effects of constant chemical fertilizer (B)
constant chemical fertilizer substituted by pig manure (A1B1
substituted by 20%; A1B2
substituted by 30%; A1B3
substituted by 40%) and constant chemical fertilizer substituted by sheep manure (A2B1
substituted by 20%; A2B2
substituted by 30%; A2B3
substituted by 40%) on the yield and composition
grain nutritional quality
flour processing quality
and water use efficiency of dryland wheat were studied. The results showed that
compared with the application of chemical fertilizer only
the combined application of organic fertilizer and chemical fertilizer can improve the yield
grain bulk density
hardness index
protein content
and flour sedimentation value of dryland wheat
and chemical fertilizer substituted by proper amount of organic fertilizer can increase water use efficiency. The effects of pig manure and sheep manure on yield and water use efficiency were different under different years. Compared with sheep manure combined with chemical fertilizer
the spike number and kernels per spike of dryland wheat were increased and the yield and water use efficiency were improved by pig manure combined with chemical fertilizer in wet year
which showed periodic drought in growth period and freezing injury in spring. Compared with pig manure combined with chemical fertilizer
the spike number
yield
and water use efficiency were increased by sheep manure combined with chemical fertilizer in dry years that had precipitation in key growth period and high water storage in fallow period. The proportion of organic fertilizer substituting for constant chemical fertilizer varies with the type of organic fertilizer. Pig manure substitute for 20% chemical fertilizer was the best
increased yield by 39.76% and 2.46% compared with the application of chemical fertilizer only respectively
and increased water use efficiency by 4.91 kg/(hm2·mm) in 2018; sheep manure substitute for 40% chemical fertilizer was the best
increased yield by 18.88% and 2.28% compared with the application of chemical fertilizer only
and increased water use efficiency by 2.57 kg/(hm2·mm) and 12.68 kg/(hm2·mm) respectively. In the two extreme years’ experiment
the reduction of chemical fertilizer combined with pig manure or sheep manure could improve wheat yield and water use efficiency
improve wheat quality
and increase soil organic matter content in topsoil. Considering from the dour qualities and the point of fertilizer saving
20% chemical fertilizer that substituted by pig manure or 40% substituted by sheep manure is recommended for the wheat production in Southern Shanxi Province.
