Treatment method of ormosia hosiei seeds

Abstract

The invention discloses a treatment method of ormosia hosiei seeds. The method comprises the following steps: in late October, before the thick cutin membranes of the ormosia hosiei seeds are formed, bean pods are collected; the bean pods are spread in a ventilated and cool place, the bean pods are blown to be split, the seeds fall out, and then the seeds are collected; the seeds are spread in the ventilated and cool place and are dried in the shade for 10 to 20 days; the dried seeds are put into chameleon solution to be dipped for 15 to 30 minutes and then flushed by clean water; the flushed seeds are put into green sand to be stored, and are stirred every 3 to 5 days; and in mid-March of the next year, when the temperature is 15 to 20 DEG C, field sowing and seeding can be performed, andbefore the sowing, the seeds are sieved out from the green sand and put into warm water to be dipped for one day. The ormosia hosiei seeds treated by the method not only improve the germination rate, but also overcome the deficiencies of slow germination and irregular emergence, thus leading the tree seed production which is difficult for seed cultivation originally to become simple and quick, and the method is easier to be popularized during the production.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a technique for raising seedlings of western Hubei red beans. Background technique [0002] At present, most of the red bean seed pods in western Hubei are picked in late November. At this time, the skin color of the red bean seeds collected at this time turns dark red, and the skin layer changes from thin to thick cuticle, which is difficult to permeate, so it is not treated. The germination rate of red bean seeds in Western Hubei is extremely low (below 10%). At present, there are no more than two ways to increase the germination rate. The first treatment method is to soak the seeds in warm water. Because the seed coat is too thick, it is difficult for the seeds to absorb water and swell. Change the water 1-2 times a day and soak for 7-10 days. The germination rate of the seeds processed by the first method is low (20.3~80.5%), and the emergence is extremely ...

[0002] At present, most of the red bean seed pods in western Hubei are picked in late November. At this time, the skin color of the red bean seeds collected at this time turns dark red, and the skin layer changes from thin to thick cuticle, which is difficult to permeate, so it is not treated. The germination rate of red bean seeds in Western Hubei is extremely low (below 10%)

At present, there are no more than two ways to increase the germination rate. The first treatment method is to soak the seeds in warm water. Because the seed coat is too thick, it is difficult for the seeds to absorb water and swell. Change the water 1-2 times a day and soak for 7-10 days. The germination rate of the seeds processed by the first method is low (20.3~80.5%), and the emergence is extremely irregular, and even some seeds germinate in the second year, which causes a lot of trouble for the field management of the seedlings; the second processing method is mechanical File the seed coat, this method has a high germination rate (about 85%), and the emergence is also neat, but this method is not only laborious and laborious, but also will damage the cotyledons and germs of the seeds if you are not careful, and the damaged parts of the seeds are easy Infected by germs and rotten (seeds will be wiped out in rainy days), directly affect the germination rate and emergence quality of seeds
