Abstract

The invention discloses an environmentally friendly nuisanceless rice planting method. The environmentally friendly nuisanceless rice planting method is characterized by comprising the following steps: culturing photosynthetic bacteria, preparing a photosynthetic bacteria solution a, preparing a base solution, mixing the photosynthetic bacteria solution a with the base solution to obtain a photosynthetic bacteria solution b, soaking a rice seedling root system in the photosynthetic bacteria solution b for 12-14 h during transferring of rice; forming a photosynthetic bacteria rhizosphere film on a rice seedling rhizosphere, and then planting. Compared with the prior art, the environmentally friendly nuisanceless rice planting method has the beneficial effects that (1) a rhizosphere bacteriafilm is formed on the root of soil by improved photosynthetic bacteria, the roots of rice are protected, mercury is stopped from entering the roots of the rice, the content of mercury in rice seeds is reduced, compared with a traditional mercury spraying technology, the method is more remarkable in effect, the amount of application is small, and the ability of stopping the rice from adsorbing themercury is excellent; and (2) the environmentally friendly nuisanceless rice planting method is environmentally friendly, while the rice is effectively stopping from adsorbing the mercury, influenceto the original ecological system of the soil and the yield of a farmland is small, and abundance of microbial population of the soil can be promoted.

Description

technical field [0001] The invention relates to an environment-friendly and pollution-free rice planting method, in particular to a method for preventing rice from absorbing mercury through the rhizosphere membrane of photosynthetic bacteria, thereby achieving the production of environment-friendly and pollution-free rice, which belongs to the field of agricultural planting. Background technique [0002] Mercury is a highly toxic and persistent heavy metal pollutant, which is listed as one of the primary control pollutants by governments. At present, due to human activities and the improvement of industrialization, a large amount of mercury has entered the soil. Some of the land has been returned to the field and planted with crops such as wheat and rice. Through the predation of the food chain, a large part will enter the human body and endanger human health. Therefore, the control of mercury in the soil has become a top priority for current environmental governance. Com...
