A kind of preservation method of jacaranda seeds

Abstract

The invention belongs to the technical field of idesia polycarpa seed preservation, and relates to a method for preserving idesia polycarpa seeds. The method comprises a step of building an intelligent control seed preservation model, a step of selecting and disinfecting seeds and a step of performing intelligent variable-temperature seed storage. The method for preserving the idesia polycarpa seeds disclosed by the invention has the advantages of long seed storage time, prevention of seed inactivation, high seed germination rate and the like.

Description

technical field [0001] The invention mainly belongs to the technical field of jatropha seed preservation, and in particular relates to a method for preserving jacaranda seeds. Background technique [0002] Jatropha is a deciduous tree that grows in deciduous broad-leaved forests and coniferous broad-leaved mixed forests such as hillsides and valleys in low mountainous areas at an altitude of 400-2500 meters. 1400 meters (southwest region) of the mountains. Jatropha grows fast, bears many fruits, and has high yield. It blooms and bears fruit 4 to 6 years after planting, and enters the flat fruit period in 12 to 15 years. Generally, the yield per plant can reach 15 to 50 kg. 20 to 40 years is the full fruit period, and the general yield per plant can reach 150 to 200 kilograms, with a maximum of more than 250 kilograms. After professional testing, the flesh of Jasmine contains 43.6% oil, the seeds contain 22.4%-25.9% oil, the average oil content is 36.3%, and the linoleic a...

Problems solved by technology

The dehydration tolerance of jacaranda seeds is relatively poor, therefore, how to maintain the moisture in the seeds is an important factor to ensure the germination rate of jacaranda seeds

[0004] Existing seed storage method generally directly is the wet sand storage (humidity is more than 60%) under the low temperature of band pericarp, yet, this storage mode has several deficiencies: (1) when wet sand humidity is insufficient, jacaranda seeds are easy to lose weight. Loss of activity due to excessive water loss

(2) When the moisture content in the seeds of Jacaranda seeds is high, the storability of Jacarnia seeds will be greatly reduced, and they can only be stored for 3 to 6 months. After 3 to 6 months, the germination rate of the seeds will be greatly reduced, and even may be 0

(3) The surface of the jacaranda seeds themselves is toxic and covered with a layer of wax, which will not only affect the germination rate of the seeds, but also dewax and disinfect the seeds before sowing in the later stage, which will cause certain damage to the stored seeds

(4) No measures have been taken to remove inferior seeds before storage, which not only takes up storage space, but also mixes with normal seeds, which is very likely to "infect" normal seeds (for example, inferior seeds may become moldy, and the mold will spread to normal seeds In, make normal seeds inactivated by mold infection)

(5) During the seed preservation period, there is no systematic regulation according to the actual situation of the seeds, which is also a key factor affecting the germination rate of the seeds
