Therefore, this study investigates the growth dynamics of the root weight, root length and root surface area of maize during the elongation stage under different mulching conditions using the root-drilling method to analyze the distribution characteristics of the root spatial dynamics and the relationship between the roots and shoots under different mulching measures, to define the regulation and control yield support capability of mulching measures on the root, to further improve the mutual aid efficiency of dry farming with benign root and soil water, and to provide a theoretical basis for developing a water-saving agriculture mode that is appropriate for cold and dry northern areas. 1 Materials and Methods 1.1 Overview of the experimental site This experiment was conducted in the Xiangfang experiment base of Northeast Agriculture University, Harbin, from April 2012 to October 2013 (126°45' east longitude and 45°43' north latitude with an average elevation of 138 m).

This method can organically combine soil heat and moisture preservation by mulching with fertility promotion and an oxygen-maintained advantage of surface tillage and effectively regulate plant growth during the elongation stage, improve the distribution of the underground roots, and enhance the root weight, root length, root surface area and root-shoot ration by a root-shoot signal mechanism to ensure the necessary material basis for the reproductive growth of maize during the later stage.

Chitosan, which is composed of 2-amino-2-deoxy-P-D-glucose, has characteristics such as easy degradation, large availability, hydrophobic and antimicrobial properties and its ability as a preservative of natural materials [8].
Based on the explanation above, the main material needed in filmmaking is chitosan obtained from shrimp waste that undergoes autolysis, demineralization, and deacetylation.
The chitosan with the highest DD in this variation is used as raw material for filmmaking.
This research was conducted in the Organic Chemistry laboratory, Department of Chemistry, Faculty of Mathematics and Natural Sciences, University of Jember.

The reason for this is that a community of different organisms produce different enzymes to degrade different substrates or materials in the wastewater as a result of this variation there is a wide umbrella of organic materials that can be degraded unlike pure cultures, which produce one kind of enzymes to degrade a specific substrate.
Comparison with findings from Huang and colleagues in 2021 highlighted higher internal resistances observed with various electrode materials like graphite felt and carbon brush, underscoring the effectiveness of the current MFC design.

An important way to characterize the defect structure in materials is by means of self-diffusion.
But in nano materials, the most fundamental concept of bulk crystal is lost and so the hopping of atoms between defects and migrating atoms could not be easily visualized.
This is the reason for the development of ab initio and simulation methods for the nano materials.
Even though models are not unique, this model calculations for nano materials need lot of discussions, as given earlier.
