The research on the biological characters and dynamic distribution of the root system has scientific guiding significance for the growth and development of crops and agricultural production.
Garlic (Allium sativumLFor cool and cool preference crops, the chord-shaped shallow root system has no main root and developed lateral root system. The garlic is mainly distributed in soil with the depth of 5-25 cm, and the transverse diameter is 25-30 cm. The garlic is rooted 5-7 days after sowing, and the final rooting number is 30-40. The garlic root system has weak water and fertilizer absorbing capacity and poor drought resistance, and needs frequent watering and frequent fertilization to promote the garlic root system to grow longitudinally and transversely so as to achieve the purposes of high yield and income increase.
The field test of garlic biological characteristic root systems requires qualitative observation and quantitative measurement of growth and distribution conditions of the garlic biological characteristic root systems, namely the number and weight of the root systems and the maximum or average depth and width of dynamic distribution of the root systems. The depth is the maximum or average longitudinal depth which can be reached by the maximum longitudinal growth of the root system, and the width is the maximum or average horizontal width which can be reached by the maximum transverse growth of the root system. The traditional root digging investigation method for qualitative observation and quantitative measurement is implemented by separating root systems from soil by utilizing manual washing, and quantitatively measuring the quantity, weight and length of the root systems, but the original distribution form of the root systems in the soil is changed along with the washing and taking processes, namely the real distribution state of the root systems in the soil cannot be accurately analyzed, the dynamic distribution width of the garlic root systems cannot be qualitatively observed and quantitatively measured, and at present, no qualitative observation and quantitative measurement method exists.
