Problems solved by technology

[0008] Although predecessors have made some progress in breaking the dormancy of Nitraria japonica seeds, these seed germination techniques are time-consuming and laborious. In addition, the control of conditions such as temperature, water and air is difficult to achieve the desired effect, and it is inconvenient to operate in the laboratory. The important thing is that the germination rate is low

Abstract

The present invention primarily relates to a method promoting the germination of the Nitraria schoberi seed. A method promotes the rapid germination of the Nitraria schoberi seed comprises the following procedures of A. the seed of Nitraria schoberi is collected, the fruit pulp on the surface of the seed is removed, the seed is dried after being washed in the water in normal temperature and finally the seed is stored in the temperature of twenty to forty centigrade degrees below zero to be prepared for use; B. after immersed in a sulfuric acid solution with a density of thirty to ninety eight percentages for half an hour to 24 hours, the seed of Nitraria schoberi seed is washed by the water to have the pH value between six and eight; the seed is sterilized in an alcohol solution of 50 percentages to 100 percentages about one to thirty minutes, the seed is washed for four to six times; under the condition of the temperature range between fifteen and forty centigrade degrees, the seed is immersed in the water for 24 to 72 hours and the seed is arranged on the seed bed for sprouting under the same temperature condition. The present invention is characterized in that the method can rapidly relieve the dormancy of the Nitraria schoberi seed in a high efficiency and can make the germination rate of the seed reach 69 percentages within ten days; moreover, the germination is orderly, which greatly save the time for breeding the seedling or breeding the seed of Nitraria schoberi.

Description

Technical field: [0001] The invention mainly relates to a method for promoting the germination of Nitraria japonica seeds. Background technique: [0002] Nitraria tangutorum belongs to Tribulus terrestae and is an important resource plant distributed in Northwest my country. It integrates wind and sand fixation, soil and water conservation, saline-alkali land improvement, pasture and medicinal materials, etc. Therefore, it is worthy of vigorous development in desert and saline-alkali areas. resource plants. [0003] The high seed dormancy rate of Nitraria has seriously limited the research and utilization of this excellent species. Predecessors have carried out many tentative researches on the germination method of Nitraria seeds, and achieved certain achievements. In general, these germination methods can be classified into 4 categories, namely sand storage, warm storage, water immersion and stratification. [0004] For germination in sand storage, first soak the Nitraria...
