[0017] 1Materials and methods

[0018] 1.1 Test materials

[0019] The local characteristic radish variety'Manshenhong' in Sichuan was used as the test material and was purchased from Chengdu Jinbaisheng Seed Industry Co., Ltd. The test soil is sandy loam soil, taken from farmland in Wenjiang District of Chengdu City. Its basic physical and chemical properties are: pH 7.09, total nitrogen 1.50g·kg -1 , Total phosphorus 0.76g·kg -1 , Total potassium 18.02g·kg -1 , Total cadmium 1.96mg·kg -1 , Alkaline hydrolysis nitrogen 94.82mg·kg -1 , Available phosphorus 6.30mg·kg -1 , Quick-acting potassium 149.59mg·kg -1 Among them, the effective cadmium content of the tested soil was not detected.

[0020] 1.2 Experimental design

[0021] Put the air-dried test soil through a 6.72mm (3 mesh) sieve and put it into pots. Each pot is filled with 2.0kg of soil. The pollution concentration is CdCl 2 ·2.5H 2 Add the heavy metal cadmium in O analytical pure form and mix it to make the ...

Abstract

The invention provides a method for evidently lowering the cadmium accumulation of Raphanus sativus and promoting the growth of the Raphanus sativus. The method includes: when Raphanus sativus seedlings grow two true leaves, using melatonin with the concentration being 50-200 micromol*L<-1> to perform leaf surface spraying until leaf surfaces can drip water. The method has the advantages that cadmium content in the Raphanus sativus can be lowered evidently, the photosynthetic pigment content, antioxidant enzyme activity and biomass of the Raphanus sativus can be increased evidently, and the inhibition effect of cadmium on the growth of the Raphanus sativus can be relieved effectively.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a method for significantly reducing the accumulation of cadmium in radish and promoting its growth. Background technique [0002] In recent years, due to the rapid development of industrial and agricultural production and the massive development and utilization of mineral resources, the problem of heavy metal pollution in farmland soil-crop systems has become more and more prominent, which also poses a serious threat to agricultural product safety and food safety. Cadmium is one of the most concerned toxic heavy metals in the environment. Its toxicity is second only to mercury and lead, ranking third. It affects the yield and quality of crops through absorption, accumulation and enrichment of plants. human health. One of the important ways for soil cadmium to accumulate is atmospheric deposition. Cadmium in the atmosphere enters the soil through natural de...
