Combined application of organic fertilizer and inorganic fertilizer is an important measure to maintain the high and stable yield of crops.Organic manure can reduce the bulk density of the soil,increase the average weight of aggregates,and then improve the soil moisture status,and play a role in water conservation.Manure are rich in nutrients,and the organic acids produced during the decomposing process will decompose the nutrients in the soil that are not active and are difficult to use,and supply more nutrients for crops.Different organic fertilizers have different properties due to their sources of fertilizer,maturity,and mineralization rates.What are the effects of different organic fertilizers on soil moisture,nutrients,and plant growth in Weibei Dryland?Morever,Weibei Dryland is typical calcareous zinc deficiency?or potential zinc deficiency?soil.because of the higher lime soil pH and CaCO3 content,ZnSO4·7H2O is easily adsorbed and fixed,Can organic fertilizer alter the availability of zinc in calcareous soil?Therefore,in this study,the field plot experiment was conducted to study the effects of applying different types of organic fertilizers on the growth and development,yield,and water and fertilizer utilization of winter wheat.Especially the availability of Zn in calcareous soil,and the zinc content of wheat grain.In order to provide a theoretical basis for improving the availability of trace elements on calcareous soils in the North.The main conclusions are as follows:1.The population quantity of the winter wheat increased firstly and decreased afterwards along with growth period.In 2015-16 year,compared with the control treatment,different organic fertilizer treatments?PM?CM?FM?CF?increased wheat yield,with an average of19.1%.Compared with the non-zinc fertilizer treatment,the yield of appiling zinc fertilizer increased 7.47%in 2015-16 year,while yield reduced 9.58%in 2016-17 year.The reasons analyzed from the components of wheat yield were that different organic fertilizer treatments could increase the number of panicles and grains per panicle compared to the control treatment,but only three types of livestock manure increased significantly.The difference in yield between the application of zinc fertilizer and non-zinc fertilizer treatment was mainly caused by the significant difference in the number of effective panicles.Organic manure between different organic fertilizers has a good effect on increasing yield production,while commodity organic fertilizer has a higher potential for yield increase.2.Without treatment with zinc fertilizer for two years,the content of zinc in grains of different organic fertilizers was lower than conventional control treatments;under the condition of zinc fertilizer treatment,the reduction range decreased,and the effect was enhanced in the second year.The zinc content of wheat treated with organic fertilizer in this year was increased by 0.94 mg/kg compared with the conventional control treatment.3.Regardless of the application of zinc fertilizer,the soil water consumption of different organic fertilizers was higher than conventional control treatments during the growth period of winter wheat,and the average annual increased 9.4mm.Similarly,different organic manure treatments improve the water use efficiency of winter wheat compared with conventional control treatments,and have a better effect in 2016-17;the difference between using zinc fertilizer and non-fertilizer application is mainly caused by the yield,which is related to the yield.4.Regardless of whether or not applied with zinc fertilizer,different organic fertilizers increased the absorption of nitrogen,phosphorus,potassium,copper,zinc,iron,manganese and other nutrients in the aboveground part of winter wheat.At the same time,soil nutrient content has also been increased to some extent.Overall,pig manure composting and chicken manure composting are effective.The effect of commodity organic manure and cow manure in fertilizing soil is similar.5.The treatment with zinc fertilizer can effectively prevent the downward migration of nitrate nitrogen compared with the treatment without zinc fertilizer.The effect of commercial organic manure is better.Therefore,organic manure have a good effect on increasing yield and efficiency,and fertilizing soil.Commercial organic manure have a greater potential for increasing production,increasing efficiency,and fertilizing soil,and are more environmentally friendly.
