Abstract
The present invention relates to a kind of method improving nutmeg seed sprouting speed and germination rate, comprise the following steps: the fruit gathering nutmeg maturation cracking (1) 8-10 month; (2) the thick fine sand of 3-5cm is applied in germination box, husky bed water tariff collection hypersaturated state; (3) remove pulp and arillus, careful divests hard seed coat, is sterilized 10 minutes by the seed of shelling, then rinse well with clear water in the clorox of 2.5%; (4) be pressed into gently in moistening husky bed by the seed after shelling sterilization, hilum is downward; (5) cultivate under germination box being placed in the room temperature condition of 25 DEG C-35 DEG C; (6) after indoor vernalization 14-16 days, percentage of seedgermination can reach more than 90%, during the long 1-2cm of root, carries out seedbed nursery according to a conventional method.The invention has the beneficial effects as follows: the speed of germination and the germination rate that improve nutmeg seed, and operation, equipment are simple, can be widely used among the cultivation of nutmeg seed seedling-raising.
Description
Technical field
The present invention relates to a kind of method improving nutmeg seed sprouting speed and germination rate.
Background technology
Nutmeg is warm in nature, and pungent, the micro-hardship of taste, has effect of warming middle energizer to promote qi, relieving diarrhea with astringents, the disease such as to vomit less for deficiency-cold in spleen and stomach, endless diarrhea, abdominal distention, food, is the famous spices in the torrid zone and valuable medicinal plant.Modern pharmacological research shows, nutmeg has the effects such as stronger anti-inflammation, analgesia.Nutmeg main product, in Malaysia, Indonesia, Indies, Brazil and other places, also has introducing and planting on China Taiwan, Guangdong, Yunnan and other places, and within 1986, nutmeg is in Hainan Introducing success.
Under field conditions (factors), sprout time is long, and germination rate is low, and seedling breeding is restricted for nutmeg seed, have impact on the plantation of myristic spread.The present invention can improve speed of germination and the germination rate of nutmeg seed effectively, and seed sprouting comparatively neat and consistent, simple to operate, cost is low, is convenient to management.Present invention reduces the field management time in seedling fostering process, be conducive to hiding the fungal diseases such as root rot and underground pests, as: grub, cutworm, mole cricket and the plague of rats etc., be conducive to the breeding benefit improving seedling.
Summary of the invention
The object of the invention is to improve myristic speed of germination and germination rate, a kind of a kind of method improving nutmeg seed sprouting speed and germination rate simple, quick, with low cost is provided.
Object of the present invention is achieved by the following technical programs:
Improve a method for nutmeg seed sprouting speed and germination rate, it is characterized in that comprising the following steps:
(1) seed screening: gather nutmeg seed grain fruit that is large, full, that ftracture without physical maturity on damage by disease and insect, the excellent elite stand of stable high yield 8-10 month;
(2) seed germination appointed condition: select transparent plastic box to be germination box, applies the thick fine sand of 3-5cm in box, husky bed water tariff collection hypersaturated state;
(3) operating technology: peel hard seed coat off, is sterilization 10 minutes in the clorox of 2.5% in concentration by the seed removing seed coat, then rinses well with clear water;
(4) dehusked seeds is pressed into gently in moistening husky bed;
(5) cultivate under germination box being placed in the room temperature condition of 25 DEG C-35 DEG C;
(6), after indoor vernalization 14-16 days, treat seed sprouting, when root grows to 1-2cm, seed seedling-raising operation requirements carries out nursery routinely.
The seed of the collection described in step (1) will avoid sunlight directly to shine, with adopting with broadcasting.
When step (3) peels hard seed coat off, avoid cut wound seed, do not injure embryo position.
Sand in germination box will be looked for novelty sand, and does not reuse.
Step (6) myristic seedling will avoid sunlight directly to shine, and when true leaf launches, adds a cover sun-proof net.
The indoor vernalization of step (6) is after 14 days, seed germination, during the long 1-2cm of root, then cultivation of transplanting seedlings.
Under conventional seed seedling-raising condition, without indoor vernalization, directly by nutmeg planting seed on seedbed.Sow after 30 days, germination rate is only 8.9%; After 37 days, germination rate is 20%; After 51 days, germination rate is 50%; Germination rate about 70% after 60 days.After planting 37 days-51 days is peak period of sprouting, and the seed of about 30% is sprouted during this period.
The inventive method has the following advantages: germinating time is short, germination rate is high.Sow after 5 days, seed just starts to sprout; Sow after 7 days, the Seed sprouting of about 30% sprouts; Sow after 10 days, the Seed sprouting of about 80% sprouts; Sow seed after 14 days almost all to sprout, germination rate reaches as high as 95%; Wherein after planting 8-10 days is the peak period of nutmeg seed germination, and the seed of about 50% is sprouted during this period.
Nutmeg seed is the seed of very valuable ingredient of traditional Chinese medicine, and conventional method is long for breeding cycle, and germination rate is low, and the present invention, compared with conventional seed seedling-raising method, not only greatly can shorten the germination cycle of nutmeg seed, be reduced to 15 days from 60 days; The germination rate of seed can also be improved, be increased to more than 90% from 70%, and simple to operate, quick, with low cost.The present invention effectively can reduce the infringement probability being subject to damage by disease and insect, effectively improves the benefit of nutmeg sapling multiplication, can promote the use of in actual production.In addition, the method cycle is short, also can as one of method of fast detecting nutmeg seed vitality.
