Abstract
The invention discloses a method for identifying a rice variety suitable for being planted in soil with what level of cadmium pollution. The method comprises the steps that five kinds of soil with the cadmium content of 0.2-0.29 mg/Kg, 0.3-0.59 mg/Kg, 0.6-0.99 mg/Kg and 1.0-1.99 mg/Kg and with the cadmium content larger than 2 mg/Kg respectively is prepared, and rice of the variety is respectively planted in the soil, and is cultivated according to a conventional fertilizer application level and a conventional planting environment; rice seeds are harvested according to different levels of the cadmium content after the rice is ripe, the cadmium content of the rice after dehulling is measured, and it is indicated that the rice is suitable for being planted in the soil with the corresponding cadmium content levels if the cadmium content of the rice is lower than 0.2mg/Kg. According to the method, through the comparison of the cadmium contents of the rice of the different varieties planting in the soil with the different cadmium contents, the low-cadmium rice variety allowing the rice with the cadmium content lower than 0.2mg/Kg to be produced in the soil with the different pollution levels is identified.
Description
Technical field
The present invention relates to a kind ofly identify that rice varieties is appropriate to the method for planting in the soil of which kind of cadmium pollution level.
Background technology
Cadmium (Cadmium, Cd) is one of China's farmland the most general contaminated heavy metal.According to Ministry of Agriculture statistics, China exceedes 10% arable land and is subject to cadmium pollution (being greater than 0.3 mg/Kg), and the grain of the heavy metal pollutions such as annual cadmium is up to 1,200 ten thousand tons.Cadmium pollution enters human body by food chain, and long-term edible meeting serious harm human health, even causes " Itai-itai diseases ".
In the rice that the cadmium content of 31 batches of the sampling observations of Guangdong Province in 2013 food peace office cloth exceeds standard, have 14 batches to come from Hunan, cadmium content is not from per kilogram 0.26 mg/Kg to 0.93 mg/Kg etc.In the face of this severe situation, promoting the low cadmium rice varieties of seed is the main path that changes this passive situation.The inventor shows in the research of the low cadmium rice varieties of natural Field Screening in Cadmium Pollution in Soils district for many years, the repeatable extreme difference of result of study, its reason mainly contains: large Tanaka different districts Cadmium in Soil content difference is obvious, the validity that affects cadmium containing the inhomogeneities of cadmium straw incorporation causes field content of organic matter difference, contaminated area irrigation water cadmium content is changeable etc.Therefore, also do not set up so far the method for the low cadmium rice varieties of a set of desirable screening, cannot realize the authentic assessment of the suction cadmium level under different cadmium content backgrounds to different rice varieties.The present invention is exactly according to a kind of method of screening low cadmium paddy rice of this great demand research invention.
Summary of the invention
The object of the present invention is to provide and a kind ofly identify that rice varieties is appropriate to the method for planting in the soil of which kind of cadmium pollution level, by the comparison to the rice cadmium content that is planted in the different rice varieties in the different soil of cadmium content, identify the suitable low cadmium rice varieties that is no more than 0.2 mg/Kg at different cadmium pollution degree soil production rice cadmium contents.
Technical scheme provided by the invention is: a kind ofly identify that rice varieties is appropriate to the method for planting in the soil of which kind of cadmium pollution level, the method comprises the steps:
(1) preparing the soil of certain cadmium content, for example, is the soil of 0.2-0.29 mg/Kg, 0.3-0.59mg/Kg, 0.6-0.99 mg/Kg, 1.0-1.99 mg/Kg and/or > 2 mg/Kg;
(2) by paddy rice plantation respectively in above-mentioned various soil, under Fertilization Level and planting environment, cultivate routinely;
(3), after paddy rice maturation, by different cadmium content level results rice paddy seeds, after shelling, measure rice cadmium content;
(4) rice cadmium content, lower than 0.2 mg/Kg, shows that it is suitable for planting in corresponding cadmium content level or lower level soil.
Described method, in step (1), every kind of soil all fully mixes, random 5 samplings, be less than+0.02mg/Kg of cadmium content difference between every, and with the soil and environment of different cadmium contents not being separated containing the isolated material of cadmium, prevents that external source from containing in the soil that Cadmium Pollutants On The Chinese enters rice cultivation.
Described method, the irrigation water of rice-cultivating be reach standard for drinking without cadmium pollution water.
Described method, N, the P of rice-cultivating, K Fertilization Level are conventional levels, fertilizer type is without conventional N, the P of cadmium pollution, K chemical fertilizer.
The present invention has following beneficial effect:
The present invention identifies that rice varieties is appropriate to the method for planting in the soil of which kind of cadmium pollution level, by the comparison to the rice cadmium content that is planted in the different rice varieties in the different soil of cadmium content, identify the suitable low cadmium rice varieties that is no more than 0.2 mg/Kg at different cadmium pollution degree soil production rice cadmium contents.The present invention has set up the method for the low cadmium rice varieties of a set of desirable screening, realize the authentic assessment of the suction cadmium level under different cadmium content backgrounds to different rice varieties, overcome the low cadmium rice varieties of natural Field Screening defect in Cadmium Pollution in Soils district as repeatable extreme difference of result of study etc.
Embodiment
Embodiment 1:
Soil incubation take Cadmium in Soil content as 0.65mg/Kg rice varieties not of the same race (table 1), step is as follows:
(1) separate with will above-mentionedly not containing cadmium soil and environment containing the material of cadmium, prevent that external source from containing in the soil that Cadmium Pollutants On The Chinese enters rice cultivation.
(2) irrigation water of rice-cultivating be reach standard for drinking without cadmium pollution water.
(3) adopt conventional N, P, K Fertilization Level rice-cultivating, fertilizer type is without conventional N, the P of cadmium pollution, K chemical fertilizer.
(4) alternate plantation 3 row of each rice varieties, more than every row 10 strains.
(5) after paddy rice maturation, divide kind results rice paddy seed, after shelling, measure rice cadmium content.
(6) measure the rice cadmium content of different rice varieties.
Different rice varieties its rice cadmium content significant difference under same environmental condition.
National standard according to rice cadmium content lower than 0.2 mg/Kg, table 1 result shows: tri-kinds of GZ63-5/M433, middle 83-49 and GZ63-5/M414 suitable at Cadmium in Soil content the ecological region planting lower than 0.65mg/Kg.And middle 83-49, middle mountain are red and 9311 be not suitable for planting under this cadmium pollution background.
