Problems solved by technology

However, the root system of the plant grows underground, and it is difficult to sample and measure the root system, and its research is relatively weak. There are few studies on the growth and development of the root system and its ability to regulate the aboveground part.

Embodiment 1

[0018] Taking corn plants as an example, adopt the method of deep soil column cultivation (length 150cm×width 50cm×depth 200cm), plant 5 corn plants in each soil column, the row spacing is 45.0cm, the plant spacing is 25.0cm, the soil columns are arranged closely, and the corn root system is measured The average depth of burrowing into the soil during the flowering period is 120cm; during the flowering period of the corn plant, the root system of the plant is cut off at 40cm and 80cm below the surface, and then the corn plant is cultivated according to the cultivation mode of the high-yield field. At the maturity stage, each corn plant is counted Yield per plant of the corn plant; samples were taken before the flowering stage and the mature stage of the corn plant, the stems and leaves above the ground were killed, dried to constant weight, weighed and pulverized, and then the samples were digested and processed by continuous The nitrogen content of the plant organs was measure...

Abstract

The invention discloses a quantitative research method for functions of different levels of root systems. The method comprises the following steps that 1, the soil penetration depth L of the plant root systems is measured; 2, in the flowering period of plants, the plant root systems are cut off at the L / 3 portion below the earth surface and at the 2L / 3 portion below the earth surface, and then theplants are cultivated according to a cultivation mode of a common high-yield field; 3, in the mature period, the yield of each plant is counted; 4, sampling is carried out before root cutting in theflowering period of the plants and in the mature period, and the nitrogen content of plant organs is measured by adopting a continuous flow analyzer. According to the quantitative research method forthe functions of different levels of root systems, due to root cutting treatment of the plants, influences of different root cutting depths on the yield and nitrogen accumulation amount of the plantsare obtained, and quantitative research of the functions of different levels of root systems is achieved.

Description

technical field [0001] The invention belongs to the technical field of plant root system research, and in particular relates to a quantitative research method for root system functions at different levels. Background technique [0002] The root system and the aboveground part of the plant are an interactive and dependent entity. The nutrients needed by the plant during the growth process are mainly obtained from the soil by the root system, and the root system plays an irreplaceable role in the construction of the source sink and the formation of yield; well-developed A strong, vigorous root system supports the full potential of crop yields. However, the root system of the plant grows underground, so it is difficult to sample and measure the root system, and its research is relatively weak. There are few studies on the growth and development of the root system and its ability to regulate the aboveground part. Contents of the invention [0003] In order to solve the above ...
