Description

A kind of Jujun grasses artificial seed production method
Technical field
The present invention relates to Jujun grasses breeding technical field, more particularly to a kind of Jujun grasses artificial seed production method.
Background technology
Jujun grasses (Pennisetum giganteum z.x.lin) are the perennial upright bunch types of grass family Pennisetum Plant, has stronger tillering ability, the general 3-4.5m of plant height.Originate in north African.The 80's of eighties of last century introduce China Fujian Success is planted experimentally, through the continuous improvement culture experiment of more than 20 years, Jujun grasses were cultivated except being adapted to China's weather soil ring at present The grass seeds in border.
The matrix such as the sawdust of tradition culture edible fungi substrate generally use are, it is necessary to substantial amounts of timber.And Jujun grasses can be replaced It is used for the culture medium for cultivating edible and medical fungi for trees, so as to largely reduce the felling to trees, protects mountain forest, reduce water and soil stream Lose.Jujun grasses can also improve soil, adjust P in soil H values.Jujun grasses contain abundant protein content, and wherein crude protein content is high Up to 10%, crude fiber content 28.5%, crude fat content 3.8%, are good animal feeds, China pastoral area is to Jujun grasses Demand it is very big.Since national policy is supported, plantation Jujun grasses can also obtain national special fund is subsidized and electricity price is subsidized etc., Therefore Jujun grasses industrial technology is promoted to be of great significance to improving farmers' income.
Planting huge fungous grass is simple, can both carry out generative propagation, also can vegetative propagation.Generative propagation percentage of seedgermination is extremely low, Stem segment with axillary bud is commonly used in production vegetative propagation is carried out using short stem cuttage.By seasonal conditions and the shadow of long-distance transport condition Ring, north seedling stem is transported to the north after generally being bred from south, and germination percentage is extremely low, and reproductive-cost is high;In addition, using cuttage Breeding needs to consume substantial amounts of maternal plant, and the interception process of short stem used in cuttage needs to expend a large amount of manpower and materials, Further increase the cost of Jujun grasses breeding.In contrast, artificial seed utilizes the feature of somatic embryo occur, it is embedded In capsule, formed and have seed-bearing performance and directly in field sowing.Main advantage is to produce not being subject to seasonal restrictions;May Quickly turn out new varieties come can also be added in gel wrappage natural seed may without advantageous component;Make manually Seed has the ability of better nutrition supply and resist the disease, so that the possibility more to grow vigorously is obtained, easy to transport It is defeated and be widely popularized.Therefore, the preparation of Jujun grasses artificial seed, is the popularization of Jujun grasses large-scale planting and breeding modes of reproduction Using offer technical support.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of Jujun grasses artificial seed production method.
A kind of Jujun grasses artificial seed production method proposed by the present invention, comprises the following steps:
S1, explant materials:The Jujun grasses stalk of maturation is taken, in soil, 22-33 DEG C of environment promotes at inter-species for oblique cuttage Axillary bud sprouting, when axillary bud sprouting about 2-5cm high, is cut the axillary bud of pennisetum sinese stem culm base with pocket knife, as explant;
S2, explant disinfection:The axillary bud material of collection is put into 75% alcohol and sterilizes 30-40s, is then placed in 10% 9-12min is sterilized in liquor natrii hypochloritis;The axillary bud after disinfection is put into sterile tap water in sterile working and cleans 3-5 It is secondary, take out dry moisture afterwards, it is spare;
S3, seed bud finishing:Axillary bud after disinfection is repaiied with sterile pocket knife and cuts upper end and irregularities, leaves base portion The cripetura section part of 1.4-1.6cm is prepared for artificial seed;
It is prepared by S4, artificial endosperm component:Artificial endosperm component is 2.5-3.5% sodium alginates, MS culture mediums, 1-3mg/L Methyl α-naphthyl acetate, 0.2-0.5mg/L indolebutyric acids, 2-3% sucrose and 0.5-1g/L activated carbons, pH 5.8-6.2;110-130 DEG C of height Warm autoclaving 20min;Cool down spare;
It is prepared by S5, artificial seed bud capsule:Endosperm gel solution 2-4ml is injected in 10-20ml centrifuge tubes;Inhaled with syringe Take 3ml1.5%CaCl2Solution, syringe needle insertion centrifugation bottom of the tube simultaneously inject CaCl2Solution, after curing 10min, forms Jujun grasses Seed bud capsule, with rinsed with sterile water 3 times;
S6, Artificial Seed Coats component and preparation:Artificial Seed Coats component is 5-7% sodium alginates, 0.8-1.2% pulullan polysaccharides With 0.3-0.6% sodium carboxymethylcelluloses;110-130 DEG C of autoclave sterilization 20min postcooling is spare to room temperature;
S7, Artificial Seed Coats bag are standby:Artificial Jujun grasses seed bud capsule is immersed in Artificial Seed Coats solution, then after being pressed from both sides out with tweezers It is put into 2%CaCl2Middle curing 20min, forms Jujun grasses Artificial Seed Coats, with rinsed with sterile water 3 times, dries surface moisture;Take conjunction The capsule shells of suitable size, use ultraviolet radiation disinfection;After artificial seed is put into, capsule shells lid is finally covered, both obtains finished product Jujun grasses artificial seed.
Preferably, will be stirred in the S2 in the explant transfer low-speed mixer by alcohol disinfecting with 30-60 revs/min Mix so that explant disinfection is abundant.
Preferably, in the S4 artificial endosperm component for 3% sodium alginate, MS culture mediums, 2.5mg/L methyl α-naphthyl acetates, 0.5mg/L indolebutyric acids, 3% sucrose and 0.9g/L activated carbons.
Preferably, the amount of taking of endosperm gel solution and the specification of centrifuge tube are determined according to the actual size of seed bud in the S5 It is fixed, and be subject to seed bud and be put into endosperm gel solution and flooded completely.
Preferably, Artificial Seed Coats component obtained in the S6 is 6% sodium alginate, 1% pulullan polysaccharide and 0.5% Sodium carboxymethylcellulose.
Preferably, then the S6 high temperatures autoclaving postcooling adds carbendazim extremely to room temperature into mixed solution Concentration is 0.25-0.4%.
Preferably, the commercially available medical capsule shells of the capsule shells used in the S7, and can be determined according to artificial seed size Do suitably sized.
Preferably, artificial seed is put into capsule shells in the S7, is remained with super absorbent resin filling inside capsule shells Complementary space, for seed water suction after planting and water conservation.
Beneficial effects of the present invention are as follows:The seedling of Jujun grasses large-scale plantation is used for by the artificial seed of breeding Demand, artificial seed prepared by this method, can make that the seedling strain heredity after breeding is good, does not undergo mutation, there is provided germination percentage, from And protect the one's best quality of Juncao.Explant of the present invention using the axillary bud of rudiment between huge fungous grass as artificial seed, can be with Make that the Jujun grasses seedling growth after breeding is more consistent, does not undergo mutation, further improve the quality of seedling.Use at the same time Artificial seed prepared by Jujun grasses, can be adapted for mechanization production, shortens the tissue cultures cycle, reduce cost, improve Production efficiency, while convenience in transport and storage, the present invention in a short time, meet business metaplasia by animal nutrition The demand of production, technical support is provided for enterprise scale, industrialization culture high-quality Jujun grasses.
