Abstract

The invention discloses a planting and cultivating method capable of achieving farmland heavy metal low accumulation, and belongs to the technical field of agriculture and ecology. The planting and cultivating method comprises the following steps pf soaking rice seeds in a chlormequat chloride solution; preparing a screening culture medium rich in heavy metal pollution; placing the soaked seeds ina prepared screening culture medium to be cultured, and screening out a low-accumulation rice seedling T0 generation; culturing T0-generation rice for 1-2 generations, and screening out plants keeping the heavy metal low accumulation character as seeds; and accelerating germination of the obtained seeds, conducting transplanting, and regularly intervening the seeds by using a mixed liquid medicine. The method for obtaining the heavy metal low-accumulation rice in contaminated soil is provided through treatment, screening and later-period medicine intervention of the rice seeds, and the effectof improving heavy metal pollution of the rice or improving the ecological environment of the heavy metal soil is remarkable.

Description

technical field [0001] The invention relates to the technical fields of agriculture and ecology, and more specifically relates to a planting and breeding method aimed at low accumulation of heavy metals in farmland. Background technique [0002] Among the soil inorganic pollutants, heavy metals are more prominent, mainly because heavy metals cannot be decomposed by soil microorganisms, but are easy to accumulate and transform into more toxic methyl compounds, and some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. [0003] Soil heavy metal pollutants mainly include mercury, cadmium, lead, copper, chromium, arsenic, nickel, iron, manganese, zinc, etc. Although arsenic does not belong to heavy metals, it is usually included in it because of its behavior, source and hazards are similar to heavy metals. Heavy metals are discussed. As far as the needs of plants are concerned, metal elements can be divided ...
