Technology for culturing artificially naturalized wild fritillaria maximowiczii freyn

Abstract

The invention relates to a technology for culturing fritillaria maximowiczii freyn, in particular to a technology for culturing artificially naturalized wild fritillaria maximowiczii freyn, belonging to the field of agricultural planting. The technology is characterized by comprising the following steps: soaking the fritillaria maximowiczii freyn seeds in warm water of 15 DEG C for 30 minutes at the temperature of -20 DEG C; taking out the fritillaria maximowiczii freyn seeds; stirring the fritillaria maximowiczii freyn seeds with the river sand uniformly, wherein the particle size of the river sand is less than that of the fritillaria maximowiczii freyn seeds, and the volume ratio of the river sand and the fritillaria maximowiczii freyn seeds is 2:1; filling the river sand and the fritillaria maximowiczii freyn seeds into a woven bag; and putting the woven bag on a sand bed of -20 DEG C below zero to freeze the river sand and the fritillaria maximowiczii freyn seeds for 7-9 days. The technology has the advantages that: the function of the antioxidant system of the fritillaria maximowiczii freyn seeds is enhanced, the germination rate of the fritillaria maximowiczii freyn seeds under drought and salt stress conditions and other adverse conditions is increased, the critical germination condition of the fritillaria maximowiczii freyn seeds is improved, the biodiversity and the ecological balance of the landscape are kept, the stress resistance and the adaptability of the fritillaria maximowiczii freyn are improved so that the fritillaria maximowiczii freyn can adapt to a new field, the introduction and domestication success rate is increased, the artificial large-area culturing of the fritillaria maximowiczii freyn is realized, and the need of keeping the ecological balance of the landscape is met.

Description

technical field [0001] The invention relates to a technique for cultivating Fritillaria verticillum, which belongs to the field of agricultural planting, in particular to a cultivation technique for artificially domesticating wild Fritillaria verticillum. Background technique [0002] Fritillaria maximowiczii Freyn is a perennial herb of Liliaceae, a rare wild plant in my country. Due to environmental pollution, Fritillaria verticillium can only survive in nature reserves. Species are interrelated and restrict each other. The extinction of one plant will cause more than 20 other organisms attached to the plant to lose their "source of life." "And die. If it is not rescued and controlled in time, the speed of the extinction of biological species will be accelerated surprisingly, the ecological environment will be destroyed, and the food web relationship will be destroyed. The consequences will be very serious. At present, the disappearance of plant species in our country is...

Problems solved by technology

At present, the disappearance of plant species in our country is accelerating. Under the influence of modern agriculture and traffic pollution, some wild plants are facing the danger of extinction.

[0003] Fritillaria verticillum itself has very important economic and use value. Their large reduction or even disappearance will bring direct losses to human beings. After many studies on artificial cultivation techniques, the cultivation was unsuccessful, and finally the method of cell engineering was adopted. However, cell engineering cannot form large-scale industrial production capacity and cannot meet the market demand for Fritillaria verticillum. Only by artificially cultivating Fritillaria verticillum in a large area can the demand for raw materials for industrial production be met. It needs to be realized by introducing and domesticating. Composition ratio, and the need to protect biodiversity and landscape ecological balance
