Abstract

The invention discloses a culture medium capable of increasing the emergence rate of paris polyphylla and a seedling raising method of the medium. The culture medium comprises a seedling raising medium and a sowing medium, wherein the seedling raising medium is formed by mixing river sand, vermiculite, a compound fertilizer and fresh cow dung according to the mass ratio of 3: 2: 1: 1.5, and the compound fertilizer comprises the following effective components in percentage by mass: 15% of N, 15% of P2O5 and 15% of K2O; and the sowing medium is formed by mixing peat soil, vermiculite, a compound fertilizer and decomposed chicken manure according to the mass ratio of 3: 1: 1.5: 1, and the compound fertilizer comprises the following effective components in percentage by mass: 15% of N, 15% of P2O5 and 15% of K2O. The culture medium can increase the emergence rate and the seedling rate of the paris polyphylla remarkably. The seedling raising medium and the sowing medium are good in air permeability and water retention performance, the requirement for root development in the paris polyphylla seed germination process is met, the formula of fresh cow dung and the like is added into the seedling medium, and it can be effectively guaranteed that the emergence rate is increased and reaches 83% or above.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a culture substrate for improving the emergence rate of Prunus diangi and a seedling raising method for the substrate. Background technique [0002] Dianzhonglou, also known as unicorn lotus, is a perennial herb suitable for growing in areas with an altitude of 1600-3100m. The seeds of Chonglou Dianchi have obvious post-ripening effect, and the embryos need to be dormant and post-ripening before they can germinate. Under natural conditions, it takes two winters to emerge from the soil and the seedlings emerge, and the emergence rate is low. Due to the long dormant period, low germination rate and unbalanced emergence cycle of the seeds of Prunus edifica, the difficulty coefficient of seed breeding increases. Under natural conditions, the germination rate of P. Due to the low reproductive efficiency, the seed yield of P. dianthus under natural conditions cannot meet the...
