Problems solved by technology

[0005] However, at present, under the condition of flooding stress, the survival rate of Lentinus edodes plants is also uncertain, and the growth rate is also significantly reduced, and the overall biomass is significantly reduced under the condition of flooding stress.
In order to improve the adaptability of shiitake grass plants to the flooded environment, most of them are cultivated by selecting shiitake mushrooms that are suitable for growing in wetland environments, which is equivalent to selecting plants suitable for survival in wet environments through the characteristics of species diversification However, there is still the problem of significant biomass decline under flooding conditions, and a better cultivation method has not been reported to improve the growth ability of Lentinus edodes to withstand flooding, nor has there been any report on the water-logging stress of different genotypes of Lentinus edodes Ability impact

Embodiment 1

[0020] The method for cultivating Lentinus edodes that is resistant to flooding stress includes screening out different genotypes of Lentinus edodes according to identification and analysis by AFLP molecular means; and then selecting at least 4 different genotypes of Lentinus edodes plants in the planting area for mixed cultivation during cultivation. growth, the cultivation method can be realized. During actual cultivation, 4, 5, 6, 8 or even more different genotypes of shiitake mushrooms can be used for mixed cultivation, preferably using at least 6 or more different genotypes of shiitake mushrooms for mixed cultivation. Of course, it is better to use 4 or 8 different genotypes of Lentinus edodes plants for the above-mentioned mixed cultivation, which is more representative and beneficial to actual analysis and application. Using more genotypes of Lentinus edodes for mixed planting can better improve its ability to withstand flooding, and significantly increase the total bio...

Embodiment 2

[0024] The experiment of this embodiment is on July 15, 2018, from the above samples, different genotypes of Lentinus edodes were selected for cultivation and growth experiments (multi-pot cultivation includes single-genotype cultivation and mixed cultivation of at least 4 genotypes) (below respectively to adopting 4 kinds and 8 kinds of different genotypes of Lentinus edodes combined cultivation method to carry out experimental analysis)), following corresponding control group is contrasted and explained, and concrete cultivation and experimental method are as follows:

[0025] In each plastic pot (63 × 41 × 13cm), peat soil and sand were mixed in a volume ratio of 1:1 as the cultivation soil, and 100g of Austrian green manure was evenly mixed into the mixture of peat and sand in each pot. Transplant 32 plants (planted in four rows and eight rows) of Lentinus edodes in good growth condition (the number of selected nodes is 1, the number of leaves is 1), and they are evenly pla...

Abstract

The invention relates to a hydrocotyle vulgaris cultivation method capable of improving water logging stress resistance, and belongs to the technical field of plant cultivation. In order to solve theproblem of poor water logging stress resistance of existing hydrocotyle vulgaris, the invention provides the hydrocotyle vulgaris cultivation method capable of improving the water logging stress resistance. The hydrocotyle vulgaris cultivation method capable of improving the water logging stress resistance comprises the following steps: determining and screening out hydrocotyle vulgaris with different genotypes by performing identification and determination by adopting a molecular means; and then, selecting hydrocotyle vulgaris plants of at least 4 of the different genotypes, and cultivating the selected hydrocotyle vulgaris plants in a cultivation area in a mixed way so as to allow the hydrocotyle vulgaris plants to grow together. The hydrocotyle vulgaris cultivation method is capable ofeffectively improving overall flood resistance of the hydrocotyle vulgaris, so that the cultivated hydrocotyle vulgaris has relatively good water logging stress resistance performance.

Description

technical field [0001] The invention relates to a method for cultivating Lentinus edodes for improving resistance to flooding stress, and belongs to the technical field of plant cultivation. Background technique [0002] Mushroom grass (Hydrocotyle vulgaris) is a perennial herb of the genus Apiaceae, native to Europe, southern North America and Central America. Lentinus edodes was introduced into my country in the 1990s. Due to its beautiful plant shape and high ornamental value, it is often used in wetland landscaping and potted plants for ornamental purposes. At the same time, Lentinus edodes has strong resistance to sewage and can purify the body, so , is also frequently cultivated in rivers, lakes and ponds for urban sewage treatment and greening plants. [0003] However, when plants are used as wetland landscaping or urban sewage treatment or greening, there is often a situation of flooding or no water, so that the cultivated plants are flooded, resulting in a decline i...
