Method for increasing germination rate of dictamnus dasycarps turcz seeds

Abstract

The invention discloses a method for increasing the germination rate of dictamnus dasycarps turcz seeds. The method is implemented according to the following steps that seed screening is carried out,specifically, in order to ensure normal germination of the dictamnus dasycarps turcz seeds, the dictamnus dasycarps turcz seeds are newly picked in the same year; fine sand screening is conducted, specifically, a 50-150-mesh mesh screen is adopted for screening coarse sand to obtain fine sand, and the obtained fine sand is sprayed with water and stirred to be uniform; the seeds are mixed with sand, specifically, the screened seeds are uniformly mixed with the fine sand according to the volume ratio of 1:3; sand storage of the seeds is carried out, specifically, the dictamnus dasycarps turcz seeds mixed with the sand is buried into land before freezing in climate; and sand and seed unfreezing is carried out, specifically, in the spring of the second year, after soil is unfrozen, the sand and seeds are dug out from the soil, and the dug-out sand and seeds can be used for seedling cultivation and planting. The method breaks through the dormancy characteristic of the dictamnus dasycarps turcz seeds, so that the survival rate of artificial planting and seedling cultivation is increased. The germination time of the seeds can be freely selected, the operability is high, the management isconvenient, and the germination rate of the seeds and the comprehensive survival rate of seedlings are high and can reach 85% or above.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for improving the germination rate of pomfret seeds. Background technique [0002] Baixianpi is the dry root bark of the plant of the genus Baixian. It has always been an important drug in dermatology. The effect of expelling wind and detoxification, killing insects and relieving itching. Therefore, Radix Cortex Dictica is a common, commonly used and widely used Chinese herbal medicine in the field of traditional Chinese medicine. Due to the special dormancy characteristics of pomfret seeds, it is difficult for pomfret seeds to germinate. The dormancy type of white fresh seeds is physiological dormancy. The seed embryo develops during the maturation process of the seed, and the morphological development of the naturally matured seed has been completed, and there is no post-ripening shape; the water permeability of the seed coat of the white f...
