Characteristics of Environment-Friendly Nutrient Elements Silicon in Soil

Abstract:

Silicon could improve soil fertility, promote crop growth, increase plant resistance to pests and harmful elements and improve yields and quality of agricultural products. Therefore, it would be theoretical significance and practical value to improve water and fertilizer conditions and apply extensively silicon fertilizers on the base of understanding silicon properties of soil in greenhouse. In this paper, the representative soils in greenhouse in Liaoning region were used to analyze the silicon change of soil. Results show that the amount of soluble silicon and amorphous silicon in protected soil were higher than those in uncovered soil, whereas the amount of active silicon in greenhouse soil was lower than that in open field. The amount of soluble silicon and amorphous silicon in 0~20cm soil layer were higher than those in 20~40cm soil layer, neither was the amount of active silicon. The amount of soluble silicon, amorphous silicon and active silicon in 0~20cm and 20~40cm soil layer increased first, then decreased with the growth of planting time.
