Container seedling raising method and seedling raising substrate for peony for oil

Abstract

The invention discloses a container seedling method for oil peony and a seedling medium. The seedling method comprises the following steps: nursery land selection, seedbed fabrication, container selection, medium preparation, nursery stock selection, transplanting and bagging and container putting, and management after transplanting, wherein the seedling medium is prepared from the following components: peat, perlite, vermiculite and a microbial organic fertilizer at the volume ratio of (5-7) to 1 to 1 to (1-3). The root is not damaged during transplanting by the method disclosed by the invention; the survival rate of nursery stock is high; the nursery stock can be planted out of season, and is not limited by the growing season; and the nursery stock does not need to be greatly trimmed when transplanted, so that the effect of immediately forming the landscape can be achieved; and the nursery stock is regular, healthy, developed in root, intact in rootball, convenient to transport, carry and unload and the like. The light seedling medium disclosed by the invention has an obvious acceleration effect on growth of ground-underground biomass of the oil peony.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for growing seedlings in a container for oil peony and a substrate for growing seedlings in a container. Background technique [0002] Peony for oil (Paeonia suffruticosa Andr. for oil) is a unique native species in my country, and it is a general name for species with high seed oil yield (greater than or equal to 22%) in the Paeoniaceae Paeoniae group. In recent years, with the rapid development of the economy and the rapid improvement of people's living standards, my country's demand for edible oil has increased year by year, and the domestic supply of edible oil is obviously insufficient. According to relevant statistics, 60% of my country's total edible oil depends on imports. Exceeded the international edible oil safety warning line. my country's oil crops are mainly herbaceous plants, and land resources are limited, so there is little room for...

Problems solved by technology

However, at present, except for the main producing areas of oil peony, most regions of the country are vigorously developing oil peony. The climate and soil conditions in non-main producing areas are very different from those in the main producing areas, especially in the hot and humid south. How to do a good job in all aspects of container seedling cultivation technology for oil peony in the region is very important. In addition, the special physiological characteristics of oil peony, the root system is fleshy root and the tap root is particularly long, which is not suitable for conventional container cultivation techniques and substrate formulations. Therefore, the container seedling cultivation technology that causes planting without seasonal restrictions has not been used for oil peony, which has hindered the further development of oil peony industry to a large extent.
