A monitoring method for the effect of bioremediation of plant root damage

Abstract

The invention belongs to the field of bioremediation, and in particular relates to a method for monitoring the bioremediation effect of plant root damage. The monitoring method includes the following steps: (1) sowing seeds, cultivating plants, and inoculating bacterial agents or inactivated bacterial agents respectively; (2) performing root damage treatment on the above-mentioned cultivated plants after emergence; (3) monitoring the stomatal conductance of plant leaves. At the same time, the thermal infrared imager is used to monitor the leaf temperature, and the water status of the plant is jointly judged according to the stomatal conductance and the leaf temperature, and the damaged state of the plant root system is judged, and the sensitive period of microorganisms to root damage monitoring and the effect of microbial restoration are evaluated. The monitoring method of the invention is more reliable and accurate.

Description

technical field [0001] The invention belongs to the field of bioremediation, and in particular relates to a method for monitoring the bioremediation effect of plant root damage. Background technique [0002] The root system is an important organ for plants to absorb water and nutrients, and the state of the root system is crucial for plant water and nutrient absorption. In fruit tree cultivation, root systems with well-developed lateral roots and many fibrous roots are needed. Such plants are more conducive to flowering and fruiting. In order to achieve this goal, the root system of the plant needs to be pruned, and root pruning before fruit tree transplantation can also improve the survival rate of fruit trees. Proper root pruning in agriculture is beneficial for plants to save water and stimulate plant growth. In arid environment, the stomatal conductance of leaves will decrease after plant root pruning, and the stomatal conductance of plant roots will increase after a per...

In the paper "Study on the Effects of Root Pruning on the Physiological and Ecological Effects of Alfalfa", root pruning experiments at different depths were carried out on alfalfa root system, and the canopy temperature of each treatment was measured at 9:00 to 10:00 in the morning at different growth periods to study the effects of root pruning on different depths on the canopy of plants. However, this experiment did not collect temperature within the daily cycle to screen the sensitive time of the daily cycle; the temperature image collected in this paper includes soil temperature, not the real canopy temperature of plants, and does not take into account the damage of microorganisms to the root system. plant effects

In summary, it can be found that monitoring methods for the effects of microorganisms on root-damaged plants need to be improved
