Embodiment 1

[0023] A preparation for inhibiting the enrichment of cadmium in rice. Each 1L preparation is made of 70mg sodium selenite and 20mL Anrongle, a product produced by Nilesco 882 LLC in South Africa.

[0024] The method of inhibiting cadmium accumulation in rice should be 0.1L / m at the tillering stage, heading stage and / or early stage of rice filling. 2 The application rate is sprayed on the foliar surface of claim 1 to inhibit the cadmium enrichment in rice; if it rains within 30 minutes after spraying, spray again; rice is planted in heavily polluted soil with cadmium.

Embodiment 2

[0026] The difference from Example 1 is:

[0027] A preparation for inhibiting the enrichment of cadmium in rice. Each 1 L of the preparation is made of 80 mg of sodium selenite and 20 mL of Anrongle, a product produced by Nilesco 882 Co., Ltd. in South Africa.

Embodiment 3

[0029] The difference from Example 1 is:

[0030] A preparation for inhibiting cadmium enrichment in rice. Each 1L of the preparation is made of 90mg sodium selenite and 30mL Anrongle.

Abstract

The invention discloses a method and agent for inhibiting cadmium enrichment in rice and aims to solve technical problems of poor effects in reduction of cadmium enrichment and high cost of existing agents. Per 1L of the agent is prepared from 60-90mg of sodium selenite and 10-30mL of Anngro which is a product produced by the South African Nilesco 882 Limited liability Company. The agent for inhibiting cadmium enrichment in rice is sprayed in a tillering stage, a heading stage and / or an early filling stage of rice, and the amount of spraying for each time is 0.1L / m<2>. The preparation method is simple, convenience in use is achieved, and demands of large-scale industrial production are met.

Description

Technical field [0001] The invention belongs to the field of agricultural product safety, and relates to a preparation and method for inhibiting cadmium enrichment in rice. Background technique [0002] Research in recent years has shown that cadmium (Cadmium, Cd) is one of the most toxic and polluted heavy metals in farmland; rice is the staple food source for more than 50% of the population in my country, but rice has the strongest ability to absorb cadmium The accumulation of cadmium in rice has caused serious cadmium in rice to exceed the standard, which has attracted the attention of the Chinese government and scientific research workers. The research on rice cadmium reducing agents that are convenient and stable in rice production is of great significance to the nutritional value of rice and food security. [0003] Chinese patent 201410056774.6 discloses a preparation for reducing the accumulation of cadmium in crops and its use, a preparation for reducing the accumulation of...
