CN104145563B - A kind of processing method of large tree cuckoo seed - Google Patents

Abstract

The invention discloses a kind of processing method of large tree cuckoo seed, main method is when gathering large tree cuckoo capsule, outside the capsule branch of division result, retains the stem of a segment length 10-20cm, to continue after adopting back to absorb nutrient, ensures seed maturity; Be positioned over after adopting back on the dry summer sleeping mat ventilated, spread out, thickness is less than 10cm, allows seed natural air drying, and temperature controls at 10-20 DEG C, is placed into next year 1-2 month.Capsule season crack after dry, the capsule do not split is exposed to the sun under being positioned over Yanguan Pass 2-3 hour, split to capsule, take out the seed in capsule, grading sieve is adopted first to remove less impurity, and then the impurity that removing is larger, be positioned in clear water after clean kind and invade bubble 10-12 hour, sowing in time after seed fully absorbs water.This technology, compared with other technologies, has and improves bud ratio more than 20%, the features such as cost is low, simple to operate.

Description

A kind of processing method of large tree cuckoo seed

Technical field

The invention belongs to field of plant growing technology, be specially a kind of processing method of large tree cuckoo seed.

Background technology

Large tree cuckoo Rhododendronprotistumvar.giganteum is Ericaceae Genus Rhododendron, and aiphyllium seeds are distributed in Yunnan Province's Gaoligong mountains height above sea level 2100 meters of-2400 meters of, negligible amounts, is minimum population plant.

Large tree cuckoo seed is capsule, season crack after ripe, seed shedding, but natural renovation ability is more weak, and having the region of large tree cuckoo distribution to arrange investigation sample ground, its renewal surveying result is as shown in table 1:

Table 1

Sample ground number	Sample area	Elite stand strain number	Natural renovation treelet strain number
				1	20m×20m	2	0
2	40m×40m	4	2
				3	20m×20m	3	2
4	20m×20m	2	4

These seeds are collected seed comparatively difficult, the position of seed generally more than more than 10 rice, seed collecting can not be arrived seed maturity and just be plucked, otherwise after season crack, seed comes off naturally on the one hand, after adopting averruncator to cut off fruit branch in addition on the one hand, when fruit branch lands, seed comes off substantially, cannot pluck seed, therefore will pluck seed before physical maturity capsule splits, just there is jejune problem in such seed, can affect the germination rate of seed.

Summary of the invention

Bad in order to solve the large tree cuckoo seed maturity existed in prior art, the problem that bud ratio is low.The invention provides a kind of processing method of large tree cuckoo seed, improve a lot by the more direct method of seed being dried or drying of the percentage of seedgermination after the method process.Its technical scheme is:

A processing method for large tree cuckoo seed, comprises the following steps:

1) when plucking large tree cuckoo seed, when having observed Some seeds and having split, can pluck, generally in November-December, the capsule pericarp picked is blueer or green, not yet full maturity, when processing, outside the capsule branch of division result, retain the stem of a segment length 10-20cm, so that the seed after adopting back continues to absorb nutrient, ensure seed maturity;

2) be positioned over after adopting back on the dry summer sleeping mat ventilated, spread out, thickness is less than 10cm, allows seed naturally dry in the shade, and temperature, at 10-20 DEG C, is placed into next year 1-2 month;

3) capsule dry in the shade after season crack, the capsule do not split is exposed to the sun under being positioned over sunlight 2-3 hour, until capsule splits, take out the seed in capsule, grading sieve is adopted first to remove less impurity, remove larger impurity again, be positioned in clear water after clean kind and invade bubble 10-12 hour, sowing in time after seed fully absorbs water.

Compared with prior art, beneficial effect of the present invention is:

The present invention is when collection large tree cuckoo capsule, and this technology, compared with other technologies, has and improves bud ratio more than 20%, the features such as cost is low, simple to operate.

Embodiment

Below in conjunction with embodiment, technical scheme of the present invention is described further.

A processing method for large tree cuckoo seed, comprises the following steps:

1) when plucking large tree cuckoo seed, when having observed Some seeds and having split, can pluck, generally in November-December, the capsule pericarp picked is blueer or green, not yet full maturity, when processing, outside the capsule branch of division result, retain the stem of a segment length 10-20cm, so that the seed after adopting back continues to absorb nutrient, ensure seed maturity;

2) be positioned over after adopting back on the dry summer sleeping mat ventilated, spread out, thickness is less than 10cm, allows seed naturally dry in the shade, and temperature, at 10-20 DEG C, is placed into next year 1-2 month;

3) capsule dry in the shade after season crack, the capsule do not split is exposed to the sun under being positioned over sunlight 2-3 hour, until capsule splits, take out the seed in capsule, grading sieve is adopted first to remove less impurity, remove larger impurity again, be positioned in clear water after clean kind and invade bubble 10-12 hour, sowing in time after seed fully absorbs water.

Improve a lot by the more direct method of to be dried by seed or drying of the percentage of seedgermination after the method process, concrete seedling growth test is as shown in table 2:

Table 2

Test repeats	Adopt the germination rate of the method process	The germination rate drying or dry
			1	84％	54％
2	87％	62％
			3	82％	63％
4	88％	52％

The above; be only the present invention's preferably embodiment; protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art; in the technical scope that the present invention discloses, the simple transformation of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen within the scope of protection of the present invention.

Claims (1)

1. a processing method for large tree cuckoo seed, is characterized in that, comprise the following steps:
