Application Of Woody Peat To Soil Quality And Millet Yield Impact Study

In the land remediation,there is a “dominant and inferior”,and the natural endowment of the new “supplement” of cultivated land is far less than that of “occupied” high-quality cultivated land.In order to solve the problem of “predominant and inferior”,it is necessary to implement “occupy and excellent”.A variety of engineering and technical measures to improve soil quality in the short term.Therefore,Muping quickly builds high-quality tillage layer by adding wood peat,and rapidly improving soil quality in a short period of time is the implementation of the national policy of “occupying the best and supplementing the best”,and also using the land policy in the county to develop the land resources through the barren hills.A good push for poverty alleviation.In this paper,in response to the problems of low soil nutrient and organic matter content and low crop yield in dryland farmland after the new remediation,the Shigu 38 was used as the tested variety,and the woody peat was added to construct the high-quality tillage layer to carry out the field experiment in Zhangping,Hebei.Set test group(FD-A1: woody peat + decomposed straw + biological excitation regulator I + conventional fertilization;FD-A2: woody peat + decomposed straw + biological excitation regulator II + conventional fertilization;FD-B1: woody peat + Decomposed straw + conventional fertilization;FD-B2: woody peat(decrease)+ decomposed straw + conventional fertilization)and control group(FD-C1: conventional fertilization).To study the effects of wood peat on soil quality and millet yield,explore the best fertilization mode,link the rapid construction technology of high-quality tillage layer with poverty alleviation and development,effectively improve the quality of cultivated land in poor mountainous areas,implement the national policy of “predominant and excellent”,increase production and income.,Huimin and the people.research shows:(1)Compared with the conventional fertilization mode,the application of woody peat can reduce the accumulation of salt in the soil tillage layer,increase the soil alkaline nitrogen,available phosphorus,organic matter,microbial biomass carbon and nitrogen content;woody peat can also add biological excitation regulator Improve soil aggregate structure and increase soil available potassium content without causing heavy metal pollution.(2)Compared with the conventional fertilization mode,the application of woody peat can increase the plant height,stem diameter,leaf number,ear position and ear length agronomic index of millet,and can promote the aboveground biomass and root organism of millet after reduction of woody peat.The accumulation of dry matter mass,woody peat can increase the number of spikes in the sample,the number of seeds,the 1000-grain weight and the average yield per mu,and the addition of biological excitation regulator II and biological excitation regulator I compared with conventional fertilization.The model increased production by 15.72% and 14.18%,respectively.(3)Compared with the conventional fertilization mode,the application of woody peat to increase the protein content of millet grains,and the addition of bio-inducing modifier to woody peat can also increase the starch content of millet grains.(4)Under the background of poverty alleviation and development in Hebei Province,the best fertilization mode was explored: woody peat + biological excitation regulator II + decomposed straw + conventional fertilization,which improved soil quality and millet yield in a short period of time,and solved Hebei Weiping to some extent.The traditional land improvement project only ignores the quality of the number of cultivated land,and links with poverty alleviation and development also effectively improves the quality of cultivated land in the poor mountainous areas,implements the national policy of “occupying superiority and complementing the best”,increasing production and income,benefiting the people and the people.
