Problems solved by technology

However, in the current situation where wild resources have been repeatedly destroyed and seed sources are getting less and less, some places plan to build artificial mother forests and seed gardens to make up for this situation (Xinchang County, named "the hometown of Kudingcha in Zhejiang Province", In recent years, the abundant Kudingcha mother tree resources have been used to carry out large-scale Kudingcha artificial cultivation, and more than 5,000 mu of Kudingcha bases have been developed), but this long-term approach cannot solve the problems faced by the seeds in the current Kudingcha cultivation. crisis, so how to store the existing seeds for a long time is very necessary, and it can also be used as a long-term supply for the construction of artificial mother forests and seed gardens, and it is also a need for scientific research
[0003] The invention patent application with the publication number CN1360817A provides a "Method for making kudingcha germinated seeds" based on improving the germination rate and effective utilization rate of seeds, which can extend the storage time of kudingcha seeds to 3 to 4 years , but this method has only briefly described sand storage and mud storage (that is, mixing and storing seeds with yellow sand or soil), and focuses on making Kudingcha germinated seeds, improving the germination rate of seeds, reducing seed waste, and has not solved the problem.

Embodiment 1

[0024] Proceed as follows:

[0025] A. Seed selection: From November to December of the harvest year, select Kudingcha seeds that are fully mature and full of kernels in that year, wash the pulp, remove impurities and empty seeds, and the goodness is more than 80%;

[0026] B, seed storage: seeds are soaked with 0.20% potassium permanganate solution, and then cleaned to get clean seeds; seeds are mixed with clean, non-polluting yellow sand (the yellow sand needs to be clean, non-polluting, and sieved through full drying) , to remove stones, impurities and coarse grains, the diameter of sand grains is less than 1mm, after mixing with water, knead it with hands to form a ball, and let it disperse when you touch it.) Mix according to the weight ratio of 1:1, and put it in a size of about 45× 70cm 2 , the air-permeable bag lined with film and pierced with ventilation holes with a hole distance of about 5cm and a hole diameter of about 2mm to about 1 / 2 of the height of the bag, th...

Embodiment 2

[0030] Carry out seed selection, seed storage, transfer storage and re-storage according to the method of Example 1, wherein when carrying out seed storage, store in cold storage until the 3rd year from January to February; Store until April to May of the fourth year; then from April to May of the fourth year, the seeds are germinated and seed-dressed and stored indoors on the sunny ground, until December of the fourth year to March of the fifth year. Those who germinate can be stored until December of the fifth year to March of the sixth year, and basically all of them can germinate, and the cumulative germination rate in two years is about 68%.

Abstract

The present invention relates to a long-term storage method for ilex seeds, and said method mainly includes the following steps: selecting current ripe, plump and clean ilex seeds, disinfecting, dressing, placing said seed in an air-permeable bag, storing in cold storage house with 0-5 deg.C for 1-4 years; starting moving the seeds stored in the cold storage house into general room from first and second month of any yeast of second to fifth year to make storage to fourth and fifth month of next year; cleaning said seeds to obtain clean seeds, germination hastening treatment, secondary dressing, storing the seeds on the ground surface exposed to the sun in the room to make germination in a continuous stream, in which making proper management. Said invention method can make storage time of ilex seeds be prolonged to 5-8 years.

Description

【Technical field】 [0001] The invention relates to a long-term storage method for seeds, in particular to a storage method for extending the storage time of Kudingcha seeds to 5-8 years, so as to meet the needs of production development and scientific research. 【Background technique】 [0002] The breeding of Kudingcha seeds is mostly sexual breeding, which is also the main breeding method for Kudingcha seeds at present. The vast majority of Kudingcha mother trees are male plants, and a small amount are female plants (about 1 to 2%). Only female plants can bear fruit, and the number of fruit can be divided into abundant and short years. If there is no fruit or few results in less years, the quality of the seeds is poor. In addition, the dormancy period of Kudingcha seeds is as long as 7 to 8 years, and the germination rate is low. Usually, after the seeds are sown in the year when the seeds are mature, it will not start to germinate until the third year, and the germination r...
