Influence of Mowing Frequency and Stubble Height to Productivity in Artificial Lawn;

The results showed that there was significant negative correlation between the aboveground energy standing crops of community and mowing frequency.

The results indicated that Cutting frequency was significantly negatively correlated with the soluble sugar content of the root and winter survival rate.

Cutting is the main use type of alfalfa, cutting frequency not only affects forage yield and itsquality this year, but also has influence on its winter surviving rate and lasting application.

Cutting is the best of applying of alfalfa, cutting frequency not only affects forage yield and its quality ,but also has influence on its winter surviving rate and lasting application.

Grey correlation analysis for effects of cutting times on Zhaodong-alfalfa production in two years;

Effects of clipping frequency on yield and quality of hybrid sweet sorghum

In C2 treatment (clipping frequency was increased), the biomass of L.

The quality of root,diameter of main root,the number and size of nodule of Lespedeza bicolar decrease with the increasing of cutting frequency;soluble sugar content of root decrease with the increasing of cutting frequency.

Based on potted plant test,the effects of different cutting frequency treatments on overground biomass and root system of Ceratoides lanata(Pursh) Howell were studied.

The thesis researches that different cutting frequency of wild Lespedeze bicolor in North China Area has effect on different root system growth and root system soluble sugar.
