Problems solved by technology

Because heavy metals are non-degradable, difficult to move and dissolve, heavy metal pollution is difficult to be decomposed by the soil's inherent ecosystem; at the same time, heavy metals in the soil will eventually enter the food chain after being absorbed and accumulated by the roots of plants, seriously endangering humans and others. biological health

Embodiment 1

[0033] The rice planting method that can reduce heavy metal content in rice of the present embodiment, comprises the following steps:

[0034] A. Disinfection of rice seeds:

[0035] a. Preparation of tea meal extract: crush the tea meal to 20 mesh, add water according to the mass ratio of 1:40, soak for two days, filter out the tea meal residue, take the supernatant, which is the tea meal extract, and set aside;

[0036] b. Disinfection: First, use the tea meal extract to dissolve strong chlorine essence at a ratio of 1:600 ​​to liquid to prepare a disinfectant; then dry the rice seeds naturally in the sun for 1 day, soak them at a ratio of 1:1.2 to liquid In the disinfectant solution, remove the seeds after 12 hours and dry them in the air; then, continue to soak the seeds in the tea meal extract according to the ratio of material to liquid 1:2, remove them after 24 hours and dry them in the air; finally, remove the seeds according to the ratio of material to liquid 1:2 3 S...

Abstract

The invention discloses a rice cultivation method capable of reducing the content of heavy metal in rice and relates to the technical field of crop cultivation. The method comprises the following steps of seed rice disinfection, germination accelerating, preparation of a rice field, sowing and seedling growth, arrangement of land for growing field rice, rice transplanting, fertilization, irrigation, pest control and harvesting. The method has the advantages of reducing the content of the heavy metal in the rice and the content of the heavy metal in soil, restoring the soil polluted by the heavy metal, and being applicable to the areas where soil is polluted by the heavy metal, and the use amount of pesticide and fertilizers can be reduced when the rice cultivation method is applied to the unpolluted areas.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a rice planting method capable of reducing heavy metal content in rice. Background technique [0002] Soil plays the role of material exchange and energy exchange between organisms and the environment, but with the development of human society, the discharge of industrial wastes has caused great damage to the environment, and the problem of heavy metal pollution in soil has become more and more prominent, especially The heavy metal pollution in the soil of the main rice producing areas has seriously threatened the food safety of Chinese residents. In recent years, heavy metal cadmium in rice and rice products has been repeatedly reported, which has sounded the alarm on the safety of staple food. Because heavy metals are non-degradable, difficult to move and dissolve, heavy metal pollution is difficult to be decomposed by the soil's inherent ecosystem; at the same time, hea...
