Cultivation medium and artificial cultivation method for portulaca pilosa

Abstract

The invention discloses a cultivation medium for portulaca pilosa. The cultivation medium is prepared from the following components including culture soil, nutrient solution and disinfection and sterilization powder. The invention also discloses an artificial cultivation method for the portulaca pilosa. The artificial cultivation method comprises the following steps: with tender stems of the portulaca pilosa as a propagation material, pruning, inserting the pruned tender stems into the cultivation medium, and spraying a certain amount of water every day with water drops dropping from leaf surfaces for suitability, thus avoiding the leaf surfaces from evaporating and wilting until rooting; and by virtue of cultivation and management for 3-4 weeks, enabling the tender stems to root and grow to become new plants. The cultivation medium and the artificial cultivation method have the advantages that the cultivation medium fully meets the needs of growth and development of the portulaca pilosa; with the adoption of the artificial cultivation method, survival rate reaches up to 98 percent, a root system of the portulaca pilosa is developed, operation is simple and is easy to grasp, and the artificial cultivation method is feasible in spring, summer and autumn and is beneficial to popularization.

Description

technical field [0001] The invention belongs to the technical field of plant artificial cultivation, and in particular relates to a cultivation substrate of purslane oleracea and an artificial cultivation method. Background technique [0002] Purslane (Portulaca pilosa) is a plant of the genus Purslane in the family Portulaca oleracea and belongs to the narrow-leaved purslane. Widely distributed in sandy land and open land along the coast of Southeast Asia and southeast China. [0003] Portulaca oleracea, stems are densely clustered and multi-branched, leaves are nearly cylindrical or narrowly lanceolate, stems or leaf axils are densely covered with white long sparse pilose, rose red flowers, about 2cm in diameter, flowering period is May-August. It has the characteristics of high temperature resistance, drought resistance, cold resistance, barren resistance, etc. It does not have strict requirements on light, and the soil pH value is required to be 5.5-7.0. It can be prepa...

AI Technical Summary

Problems solved by technology

For field production, it takes a lot of time and effort

[0008] (2) Cutting propagation: The survival rate of conventional cutting propagation can reach about 70%-80%, which is a waste of wild plant germplasm resources

[0009] (3) Tissue culture propagation method: demanding conditions, strong technicality, not conducive to popularization

Chinese patent CN103288538A discloses a cultivation soil for fruit trees, including mountain mud, garden soil, river sand, humus, sawdust, compost, bone meal, disinfectant and pH regulator, wherein the disinfectant is peracetic acid and chlorinated trisodium phosphate One of them, the pH regulator is one of slaked lime and baking soda. The culture soil has good water holding capacity, appropriate specific gravity, and comprehensive nutrition, but it is only suitable for various fruit trees, not for purslane.

Chinese patent CN103274819A discloses a culture soil for flowers, including mountain mud, garden soil, humus, plant ash, compost, disinfectant and pH regulator, wherein the disinfectant is one of potassium permanganate and hydrogen peroxide, and the pH regulator It is one of quicklime and soda ash, and the cultivation soil is alkaline cultivation soil, while purslane requires a soil pH value of 5.5-7.0, so this cultivation soil is not suitable for purslane

[0013] In summary, there is no cultivation medium and corresponding artificial cultivation techniques suitable for cultivating Portulaca oleracea.
