Description

Sabina vulgaris seed seedling-raising method
Technical field
The invention belongs to plant propagation technical field, be specifically related to a kind of Sabina vulgaris seed seedling-raising method.
Background technology
Sabina vulgaris (Sabina vulgaris Ant.) is Cupressaceae, and the evergreen needle shrub of garden cypressCypressus, is good Sand-fixation Tree.Existingly can be applied to the method that Sabina vulgaris seedlings is bred, be mainly to realize by root, the stem nutrition organs of cuttage and press strip Sabina vulgaris.
Cuttage Sabina vulgaris branch is bred owing to being subject to cuttage branch quality, and cuttage branch stores, transportation, and the cuttage degree of depth is wayward, and the impact of the factors such as cuttage personnel qualification, causes cuttage Sabina vulgaris plant percent lower; Press strip Sabina vulgaris root, stem raising technology are applicable to, to the transformation of original Sabina vulgaris forest land and expansion, not be suitable for large area cultivating seedlings and afforestation.
Seminal propagation is that plant corpus is propagated and the important channel of breeding filial generation, by Sabina vulgaris seed carry out Sabina vulgaris seedlings cultivate be to existing Sabina vulgaris seedling-wood breeding technology supplement and perfect.For example, but there is many difficulties in Sabina vulgaris seed seedling-raising technology at present: 1. will gather in time and science modulation to the cone after Sabina vulgaris maturation, to improve the quality of seed; 2. before how Sabina vulgaris seed being broadcast, carry out maturation process; 3. How to choose date of seeding, thickness of earth covering, sowing depth; 4. how to carry out seedling management and the extermination of disease and insect pest.
Summary of the invention
The object of the invention is to overcome above-mentioned the problems of the prior art, a kind of reasonable is provided, the Sabina vulgaris seed seedling-raising method of easy operating.
To achieve these goals, the technical solution used in the present invention comprises the following steps:
The first step, seed collection and modulation;
When cone becomes puce from yellow green, pulp deliquescing, seed is gathered when milky becomes yellowish-brown, and the cone of gathering is squished and puts into water and repeatedly wash by rubbing with the hands, floats pericarp, pulp and floater, dry standby, the seed that obtains modulating;
Second step, carries out maturation process to the seed modulating;
The 3rd step, sowing;
The time of sowing is controlled at for 7~August; First seedbed is processed, be included on sand ground pad soil, pad soil thickness is 15~20cm, by garden flatten, flood irrigation, plough deeply after applying base fertilizer, carry out soil disinfection simultaneously; Then the seed after bunch planting slaking on the seedbed of processing, sowing depth is controlled at 1~1.5cm;
The 4th step, covers sowing complete seedbed;
The 5th step, seedling management and the extermination of disease and insect pest;
A. seeding stage: keep seedbed moistening, the destruction of control chafer to seedling;
B. after seedling all sprouts: the reduction ground temperature of spraying in time suffers day bright harm and suffers from drought vertical withered to prevent seedling;
C. seedling grows after true leaf: damping off and underground pests are prevented and treated;
When d. seedling growth is accelerated: apply urea in conjunction with pouring water and accelerate seedling growth.
Described maturation process adopts following any one mode:
1) employing temperature is the warm water of 60 ℃~80 ℃, soaks seed 3~5 days;
2) adopt naa 100ppm solution, soak seed 24 hours;
3) adopt 0.2% potassium nitrate solution, soak seed 10 minutes;
4) adopt 10ppm phloroglucin, soak seed 24 hours.
Described soil disinfection is that mu is executed 30 jin, ferrous sulfate.
Described bunch planting seeding row spacing is 15 * 15cm.
The complete seedbed of described cover-seeding adopts the sandy soil mixture of sand or 1:1.
The method of described control chafer adopts 5~7 kgs/acre of 3% methyl different sulphur phosphorus granule or 5% phoxim granules, in conjunction with whole plough under underground.
The described method of preventing and treating damping off adopts sprayed equivalent formula Bordeaux's solution or 1% copper-bath once to seedbed every 10 days.
Described control underground pests adopts the poison bait of the 1:100 that chlorophos and stir-fry wheat bran are made to be sprinkled upon seedbed and in the ranks kills.
When described seedling growth is accelerated, in conjunction with the urea amount applying of pouring water, it is 10 jin every mu.
Compared with prior art, the present invention carries out Sabina vulgaris seedlings cultivation by Sabina vulgaris seed, first select the cone of maturation of collection, and modulation obtains well-developed seed for cultivating from cone, then seed is carried out to the object that slaking reaches softening kind of skin and vernalization, afterwards the seed after slaking is carried out to bunch planting on the seedbed through sterilization, to sowing complete seedbed, cover again, seed sprouting is afterwards according to taking corresponding management method each seedling stage, and the damage by disease and insect occurring each seedling stage is prevented and treated in time, finally complete breeding of Sabina vulgaris nursery stock.The present invention can effectively solve the deficiency that in the past adopts cuttage and press strip to breed, overcome Sabina vulgaris and by seed, be difficult to the technical bottleneck of breeding, the survival rate of tree seedling is reached more than 80%, the screening that Sabina vulgaris seed seedling-raising is Sabina vulgaris improved seeds simultaneously provides larger possibility, by seed growing Sabina vulgaris nursery stock, can be applicable to large-area cultivating seedlings and afforestation, in the field of checking winds and fixing drifting sand, have great importance.
