Abstract
The invention provides a walnut seed seedling culture method, and belongs to the technical field of fruit tree seedling culture. The walnut seed seedling culture method mainly comprises the steps of seed collection, seed storage, seed soaking, culture substrate preparation, seed sterilization, seed pot transplanting and the like. The method concretely comprises the following steps that the culture is carried out in a culture room, the indoor temperature and humidity are controlled, in addition, water or nutrition solution is regularly added every week, and the water holding content of the culture substrate is maintained. The walnut seed seedling culture method has the advantages that the scientific standardized and scaled culture and management method is adopted for carrying out seedling culture on walnut seeds, the seedling culture period is generally shortened, the seed dormancy is fast broken, further, the seed sprouting time is shortened, the bud ratio is high, the buds are regular, the growing speed of young seedlings is high, the nutrition is rich, the disease-resistant and insect-pest-resistant capability is high, in addition, the control efficiency is high, and the survival rate and the planting building rate are high.
Description
Technical field
The invention belongs to fruit tree seedling culture technical field, be specifically related to a kind of Walnut Seed seedling-cultivating method.
Background technology
Walnut is a kind of important oil plant fruit tree, and economic worth is very high.Walnut kernel is except being rich in fat, and the content of protein, vitamin and several mineral materials is also very high, a kind of high tonic of Chang Zuowei, and has certain medical effectiveness.
Presprouting of seeds technology is an important step in walnut nursery.Traditional seedling-cultivating method comprise cool stratification vernalization, spring trickle quick pregermination, the vernalization of water logging solarization method, bowssening vernalization or directly carry out autumn sowing, generally have that cost is low, easy to operate, the simple feature of facility, but have the defects such as higher seed rate, germination time are long, bud ratio is low, it is uneven to emerge, program is various, poor controllability simultaneously.
Therefore, how research shortens growing-seedling period, improves bud ratio, and controlling vernalization environment and make emerge neat systematization, intensive, normalized high quality seed seedling-cultivating method, is the key subjects faced at present.
Summary of the invention
Technical problem to be solved by this invention is the defect making up prior art, and provide a kind of Walnut Seed seedling-cultivating method, the method nursery is rapidly and efficiently, scientific and normal, highly shortened growing-seedling period.
To achieve these goals, the present invention adopts following technical scheme:
A kind of Walnut Seed seedling-cultivating method, comprises the steps:
(1) gather seed: the Walnut Seed of sowing, generally gather in early September, the mark of kind walnut maturation is: at exocarp by green flavescence, should have during 50% cracking and gather; Answer selection adaptation strong, high yield, stable yields, shell reveals, kind of benevolence is enriched, and it is easy to get benevolence, kernel percent and oil content high, robust growth, the fine individual plant that life in 20 ~ 30 years is above, as seed collecting elite stand, from tree crown peripheral and, top gathers, because the seed light that this position gathers is according to sufficient, physically well develop, kind benevolence is full, germinating capacity is strong, and in not adopting, thorax fruit makes seed;
(2) store seed: loaded in gunnysack or basket basket by the seed chosen, be placed on cool place, the indoor of the drying of ventilation, humidity should rest in less than 5 DEG C, wants running check in storage, notes insect protected, protection against rodents, moistureproof, solar heat protection;
(3) soak seed: soak seed, 4 DEG C of pretreatment 3 ~ 4 days with 500mg/L alar-85+200mg/LGA3+1mg/L6-BA;
(4) prepare culture matrix: the high pressure steam sterilization 15min under the condition of 120KPa by commercially available peat soil and vermiculite, by weight ratio peat soil and vermiculite (5:1) are evenly mixed composite soil, composite soil is put into length of side 5-7cm, high 6-10cm, inside the little basin of beneath perforate, fill soil for little basin body long-pending 2/3 ~ 4/5, then the length of side 22 × 30cm is put into by unified for little basin, in the plate of high 2-4cm, for subsequent use, for preventing soil dry, add a small amount of water or nutrient solution (nutrient solution: by urea 10g, potassium dihydrogen phosphate 4g, calcium sulphate 2g, magnesium sulfate 1g, zinc sulphate 0.005g, iron sulfate 0.006g, copper sulphate 0.002g, manganese sulphate 0.006g, boric acid powder 0.003g, add water 10L, namely make after dissolving),
(5) disinfection seed: first use the alcohol of 75% by seed disinfection 1min, then use 1-4% hypochlorite disinfectant 10 ~ 20min, with deionized water rinsing 5 ~ 6 times;
(6) seed moves basin: every basin kind 1 seed, and matrix covers seed, and the degree of depth is about 2 times of seed diameter, is positioned over by culture plate in culturing room on culturing rack,
(7) controlled condition: be provided with air-conditioning in culturing room, controlling indoor temperature is 29 ~ 34 DEG C, installs thermometer and monitors; And humidifier is installed, control room humidity is 70 ~ 80%; In dish, add water or nutrient solution weekly on time, keep culture matrix maximum water-holding capacity to be 80%; Treat that seedling is grown up, disease-resistant bactericidal liquid can be sprayed weekly on plant by demand; Controlling the photoperiod is that 8h(is dark)/16h(illumination), intensity of illumination is 100-250umol/m
2/ s;
(8) grafting: early April next year cuts a grafting.
Beneficial effect of the present invention:
The present invention adopts scientific, standardization, large-scale cultivation and management method carry out nursery to Walnut Seed; overall reduction growing-seedling period; break seed dormancy fast; and then shorten the seed germination time, improve bud ratio high, sprout neat; seedling growth is quick, nutritious; disease-resistant, insect pest ability is strong, and administers efficient, survival rate and planting rate high.
