Problems solved by technology

[0004] In the research field of reducing cadmium content in vegetable crops, the application of exogenous hormones is one of the main means, but the application of exogenous hormones can easily cause soil degradation, and the hormones remaining on the surface of crops may cause health and safety problems

Embodiment 1

[0021] 1. Raw materials:

[0022] Radish: Weixian green radish

[0023] Soil: collected from the experimental base of Sichuan Agricultural University (without heavy metals)

[0024] Compound fertilizer: on the basis of decomposed cow dung, adjust the content of N, P and K to 15%;

[0025] Fermentation strain: Aspergillus niger A46 CGMCC No.3084, commercially available

[0026] Shepherd's Purse: Commercially available

[0027] 2. Experimental method

[0028] (1) After breaking the shepherd's purse, add water to a solid content of 70% (w / w) as a fermentation substrate; carry out liquid culture with Aspergillus niger A46CGMCC No.3084, and take the bacterial liquid that has grown to the plateau stage as the inoculated bacterial liquid , added to the fermentation substrate, the inoculum amount was 3% (w / w); covered with film, and composted and fermented indoors, the fermentation time was 3 days; after the fermentation, the water content was adjusted to 27% (w / w) ), as the ferm...

Embodiment 2

[0036] On the basis of Example 1, CdCl2·2.5H was added to the tested soil 2 O is analytically pure, so that the soil cadmium concentration is 5 mg kg -1 . On this basis, the experiment of Example 1 was repeated to investigate the cadmium content in the radish. When the relevant experimental data were obtained, three repetitions were performed, and the average value was taken. The results are shown in Table 2.

Abstract

The invention provides a cultivation method for improving radish quality, which comprises the following steps: when two true leaves of each radish seedling are expanded, applying leavening of leaf-leaf shepherd's purse to the root; the leavening of the shepherd's purse is obtained by fermenting the whole herb of the shepherd's purse as a fermentation substrate and aspergillus niger A46 CGMCC No.3084 as a zymophyte. According to the method, the biomass and the root weight of the radishes can be well improved; the content of crude fibers can be obviously reduced, the content of protein is obviously improved, the content of malonaldehyde is obviously reduced, and the content of vitamin C is improved; the method can also significantly reduce the cadmium accumulation amount in the radishes.

Description

technical field [0001] The invention belongs to crop cultivation technology, and relates to a cultivation method for improving the quality of radish. Background technique [0002] Radish is a cruciferous 1-year or 2-year herb, which is a kind of vegetable crop with edible, processing and medicinal value. Radish can enhance the immune function of the body, remove heat toxins in the body, smooth qi, and aid digestion. It also has edible and medicinal value because it contains minerals, amino acids, fructose, crude fiber, glucose, vitamin C, sucrose and a small amount of crude protein. [0003] The growth quality indicators of radish include protein, vitamin C, organic acids, crude fiber, soluble sugar, malondialdehyde content, etc. At present, researchers are also concerned about the content of related heavy metals (such as cadmium) in radish. Fertilization technology is commonly used to improve the growth quality of radish. For example, Chen Mai et al. studied the effect of ...
