Abstract
The invention discloses a crape myrtle seedling overwintering early promotion culture method, and belongs to the technical field of seedling culture. The method mainly comprises the following steps of 1, time selection, 2, seedling bed manufacturing and pot ranging, 3, sterilization and watering, 4, ear picking and cuttage, 5, post-cuttage management, 6, overwintering, 7, early spring seedling promotion, and 8, transplanting. The method has the advantages that crape myrtle seedlings cultured through the method can safely go through the winter, in addition, the advanced growth for more than 1 month can be realized in a greenhouse, and the seedling recovering is not needed after the crape myrtle seedling planting. Compared with summer tender branch cuttage seedling culture, the culture method has the advantage that the seedling height in the current year can be increased by 30 to 50cm.
Description
Technical field
The present invention relates to stock growing technical field, particularly a kind of crape myrtle seedling is survived the winter and is early urged cultivation method.
Technical background
Lagerstroemia machaka or dungarunga are important sight flower seeds in China summer, have that the florescence is long, pattern is abundant and the advantage such as antipollution, are mainly used in Landscape, street tree, potted landscape etc.
Crape myrtle seedling-cultivating method mainly contain seeding and seedling raising in spring, spring hardwood cutting and seedling raising and summer epicormic branch cutting.Spring seeding and seedling raising because of cost low, reproductive speed is fast, by flower-grower's extensive use, but because of crape myrtle be cross pollinated plant, seeding and seedling raising can produce a large amount of variation plant, causes pattern to mix, and has a strong impact on view and afforestation effect, applies just fewer and feweri.Spring, hardwood cutting and seedling raising was because vegetative propagation, and pattern is consistent, extensively adopted at present, but required that cutting orchard area is large, and time elasticity is little, and reproductive speed is relatively slow.Summer, epicormic branch cutting was not only vegetative propagation, pattern is consistent, and require that cutting orchard is relatively little, seedling germinates and takes root soon, Fast-propagation is convenient to when property is planted in guarantee, can also save and a large amount of introduce a fine variety expense, be important means and the approach of introducing new varieties and Rapid Popularization, there is higher application value.Crape myrtle epicormic branch cutting in summer is transplanted general summer and autumn, as nursery is excessively slow, then cannot field planting to land for growing field crops, or because freeze injury seriously affects planting percent after field planting, to the fast-propagation generation certain influence of crape myrtle new varieties.
Summary of the invention
The present invention is directed to the problem in background technology, have studied a kind of crape myrtle seedling and to survive the winter early short cultivation method, crape myrtle seedling safe overwintering can be made, and grow in advance early spring.
A kind of crape myrtle seedling is survived the winter and is early urged cultivation method, mainly comprises the following steps:
1, selection of time
Seedling raise period is for by the end of August at the beginning of-9 months;
2, seedbed makes and pendulum alms bowl
Bedding in canopy, wide 1-1.2m, require that furrow face is smooth, soil is in small, broken bits, furrow more than ditch depth 10cm; Pressed by machine non-woven fabrics nutritive cube to put on furrow face together with plastic pallet, requirement is put closely smooth, does not leak soil;
3, sterilize and water
Nutritive cube disinfection is sprayed with 800-1000 times of carbendazim before nursery; A water is sprayed on furrow face before cuttage;
4, fringe and cuttage is adopted
Adopt semi-lignified current-year branch, cut length 4-6cm, meropodium 1 saves, and pipe nipple 2 saves, and removes unnecessary blade in cuttings, stays top 1-2 sheet leaf; The cuttings sheared is placed on carbendazol wettable powder 800-1000 times of immersion bubble 3-5 minute; The general 3-5cm of the cuttage degree of depth; Be inserted into the blade and blade shank position that top stays in principle, cuttage too shallow being not easy survives, and cuttage is too dark in blade 1/3 is inserted soil, and within second day, cuttings there will be rebound phenomena, affects survival rate;
5, management after inserting
5.1 rooting treatment: set in water spray end in the afternoon sun, spray 20% methyl α-naphthyl acetate, 8000-10000 times of liquid+800-1000 times of carbendazim after blade is slightly dry for after inserting 1-2 days; Interval is sprayed once for 5-6 days again;
5.2 water managements: close canopy moisturizing for 10-15 days, stratification after inserting, fine day spray in 10-30 minutes water, one time 15-20 seconds; 1-3 hours cloudy daies once; From field 60% germinate to height of seedling 15cm based on hestening rooting; Suitable control water urgees root, and hardening of ventilating;
5.3 temperature control: early stage is stuffy, and the middle and later periods is aeration-cooling hardening progressively, unlimited canopy room always temperature drops to 0 DEG C before, allow crape myrtle seedling leaf-fall;
5.4 illumination control: full sunshade in early stage, and the middle and later periods is transitioned into full exposure gradually by fine day sunshade at noon;
5.5 control worm;
6, survive the winter
After crape myrtle seedling leaf-fall, winter temperature evenly spreads one deck fine earth lower than before zero degree on nutritive cube, spray once permeable, allow space between fine earth closely knit nutritive cube, and make nutritive cube matrix moist, and then at the thick straw of nutritive cube upper cover 20-30cm, lid layer plastic film again on straw, surrounding compacting, survives the winter booth sealed thermal insulating;
7, seedling is urged early spring
When germinateing to seedling at the beginning of by the end of February-3 months next year, first throw off the plastic film on straw, after seedling adapts to several days, take out straw the morning in fine day, water once permeable, leak informaton from top, booth two when day temperature raises, close canopy in the afternoon in time;
8, transplant
Mid or late March can be transplanted in booth, and April, early and middle ten days temperature went up rear field planting to land for growing field crops; A control aphid before transplanting, and mu executes 3-5 kilogram of urea, sprays once permeable; During transplanting, nutritive cube is directly planted in soil, be as the criterion with soil lid overnutrition more than alms bowl 2cm, prevent nutritive cube to basset the dead seedling of dehydration, and water in time; Transplanting Density is determined according to need of production.
Spray water in described step 3 and to be advisable so that nutritive cube half is moistening.
In described step 2, machine pressure non-woven fabrics nutritive cube nutrient matrix is filled in non-woven fabrics by machine the cylinder being cut to diameter 4cm, high 10cm, and bottom nutritive cube, flat mouth is without base fabric; Finished product is loaded in carton, and general every case fills 7 layers, and every layer has a plastic pallet, the wide 28cm of pallet, long 56cm.
Control worm in described step 5.5 to prevent eliminating aphis for adopting Imidacloprid+dichlorvos or Acker Thailand.
Beneficial effect of the present invention:
The crape myrtle seedling of being cultivated by this method not only can safe overwintering, and can grow 1 wheat harvesting period in advance in booth, and crape myrtle seedling is slow seedling after planting, and compared with summer epicormic branch cutting, height of seedling can increase 30-50cm then.
