查询词典 soil

Among the three types of parent material,the yield of rape( above-ground dry weight) was the best(NPK treatment was the best in purplish soil ), Quaternary red soil and in granitization red soil were followed respectively(both of the two types of parent material have weak growth vigor and have a consistent yield). 2.With plant rape,NPK treatment could get more harvest among the three types of parent material , M treatment and CK were followed restectively.

Flumioxazin degrades relative ly slowly and its half- life in soil was 10.0-10.5 days, but in the soil, green soybean and so ybean residual flumioxazin was not detected. The results showed that the re sidu al pollution of flumioxazin is negligible, so the application of flumioxazin is safe for the soil and soybean.

Then the pile-soil stress characteristics and stabilizing mechanism of the composite foundation are fully discussed. Based on the close analysis of the influence factors of the vertical bearing capacity, circular aperture extension theory is employed to establish the computing formulas for the pile vertical stress and the foundation vertical bearing capacity, respectively. Moreover, with analyzing the features of the calculation parameters such as materials of gunite mortar, jet pressure, diameter of the jet pipe, pile length, pile layout, a design theory for chemical churning pile composite foundation is proposed. Then, the variation of the pipe deformation with loads, the deformation coordination of pile and soil are studied. And methods to decide pile-soil stress ratio and the compressive modulus are developed. Meanwhile, the corresponding design method and the design parameters are proposed. In addition, studies for construction technique and quality detection of the chemical churning pile composite foundation are presented.
