Abstract:

Soil texture is one of the basic physical properties of soil, which reflects the composition of soil particles with different sizes and diameters. Soils with different texture have different nutrient contents, soil microbial species and activities, and also have different property of water storage and thermal insulation. Soil texture affects the fixation, transformation and loss of fertilizer absorption, and further influence the growth and yield formation of plants. Although the improvement of rice fertilizer utilization has always been a research hotspot, few have been studied of soil texture on fertilizer utilization and rice growth. After briefly introduced the differences in nutrient content, physical and chemical properties of soils with different textures, and the effects of soil texture on crop growth, the paper further evaluated the soil testing and formula fertilization technology in rice production, and discussed the efficient fertilization method according to soil texture.

Key words: soil texture, soil fertility, crop growth difference, fertilization method
