Abstract

The invention discloses a method for breeding and growing seedlings for Litsea coreana, comprising the following steps: dipping the seeds of an eagle tree, removing wax, moisturizing and stacking to swell; sowing the seeds in a seedbed; covering one layer of fine soil; then covering a grass curtain or straws; sowing between July and October; watering and carrying out fertilizer application management for the young seedlings of the Litsea coreana in March and April in the coming year; transplanting the young seedlings for the first time when the young seedlings grow to the Rain Water in the third year; and transplanting the young seedlings for the second time from the fifth year to the tenth year. The rate of emergence of the mode of breeding the Litsea coreana nursery stock by sexual reproduction is 95%, and the development and the utilization of the Litsea coreana can be produced on a large scale.

Description

A kind of method of eagle tea seed propagation seedling

Technical field

The invention belongs to the technical field of ancient tea tree exploitation plantation, especially a kind of method that adopts eagle tea seed propagation seedling.

Background technology

In multiple ancient tea kind, eagle tea claims ebon tea again, and it does not belong to usually the tea tree plant of alleged Theaceae, but belongs to Guizhou Province, river Machilus nanmu (Machiluschuanchienensiss.lee) or Guizhou Machilus nanmu (M.rehderi) in the canella.Eagle tea is arbor, the height of tree reaches 7 meters to 12 meters usually, trunk is upright, wooden fine and closely woven be the building or the good material of top-grade furniture, and its browse is a first-class raw material of making the eagle tea beverage, the eagle tea of drinking among the people has very long history in our Guizhou, relieves summer heat with it to quench one's thirst, distinguish the flavor of giving off a strong fragrance, difficult turning sour, and also has certain medical value.Eagle tea is evergreen all the year round, is again the good seeds that are used to afforest.The breeding of eagle tea: a kind of is that vegetative propagation is cuttage, but survival rate is low, another kind of is sexual propagation, and promptly fruit maturation is fallen on the mud spontaneously, and emerging seldom or holding the food fruit and seed in the month by birds grows new sapling with discharging into again in body.Yet there are no the precedent that artificial employing eagle tea seed is successfully grown saplings.Succeed with old tea seed propagation seedling in calendar year 2001 through thousands of inferior experiments of groping for many years.

Summary of the invention

The objective of the invention is in order to adopt seed to carry out growing nursery and culture and large-scale develop and utilize to eagle tea, the spy provides a kind of method of eagle tea seed propagation seedling.Adopt the mature seed of eagle tea tree to remove surperficial wax, at place backlight seed is covered in wherein on rebasing under with river sand or fine sand then, preserve moisture and stacked 30 to 60 days through washing by rubbing with the hands behind the emerge in worm water; In ready-made spill seedbed, cover one deck fine earth through the eagle tea planting seed of having swollen after the above-mentioned processing again through stacking, cover with straw screen or mat or stalk behind the water-sprinkling, sowing time is the 7-10 month, the coming year, late March was thrown off covering to April, and the eagle tea seedling that sprouts is watered and fertilizing management.The seedling that sprouts grows to the 3rd year and carries out the transplanting first time before and after the rainwater joint, carries out the transplanting second time by the 5th year to decade.

Its above with emerge in worm water eagle tea seed, water temperature is 35-50 degree centigrade, soak time is 1-2 hour, washes by rubbing with the hands then and removes the surface of the seed wax; Described seed is preserved moisture and is stacked it river sand or fine sand thickness rebasing and last covering are 2-3 centimetre down.The concavity seedbed is done in the seedbed, the sowing plane that promptly is the seedbed is lower than the ridge, edge, seedbed all around, eagle tea planting seed density be between every seed all around spacing be 5 centimetres, for the first time eagle tea seedling replanting is best during before and after the 3 years rainwater joints of growth of seedling to that sprout of sowing 15 days.

Adopt the good effect of the technical program to be: adopt this sexual propagation mode with eagle tea cultivating seeds seedling, can improve emergence rate and reach 95%, eagle tea is planted can scale.

Embodiment

One, the collection of eagle tea seed: the annual lunar calendar of the eagle tea tree in mountain forest last ten-days period in June to the beginning of July is blossomed and had seeds in the open air, to must be that maroon time side is a mature seed by xanthochromia again by the blue-stain Huang at fruit, in the fruit growth process, the spray of in good time plucking old tea tree New Development in spring, reduce fruit prematurity shedding, when being about to maturation, should take measures to prevent the unfirmly closing food.

Two, the seed of Cai Jiing is washed by rubbing with the hands and is removed surperficial wax 35-50 degree centigrade emerge in worm water one to two hour.

Three, seeds treated is poured on the river sand or fine sand of preparation, and then covers with river sand or fine sand, the husky thickness of the sand of pad and lid is all at 2-3 centimetre, being deposited in place backlight swells the seed suction, be commonly called as " sweating ", river sand keeps humidity with anhydrous outflow degree of being, pilling up time 30-60 days.

Four, preparing seedbed and sowing.The seedbed is with groove type or plane formula seedbed, and bed ground bed mud soil is smooth, softer, use foot-operated or other beating method compacting before the sowing again, about 5 centimetres of spacings are placed between every seed, cover one deck fine earth or detritus soil again, rock nest mud is better, sprinkle to go up behind the water straw screen or mat or maize straw covers.The wetting anti-arid of seedling ground protection, the sowing time 7 between October.

Five, wash water and fertilizing management; after planting last ten-days period in March, second to taking away straw screen or mat or other coverings between April; just can see the tender shoots that seed grows white; at this moment spill clear water or clear liquid dung, can not use chemical fertilizer, a spot of chemical fertilizer in after sprouting 1 year; and protect moistening; forbid to use weed killer herbicide or other agricultural chemicals full vegetative period tea seedling, emerge and carried out the transplanting first time before and after the rainwater joint on the 3rd year, carry out the second time in the 5th to ten year and transplant.

Claims

1. the method for an eagle tea seed propagation seedling, it is characterized in that: the seed of the maturation of employing eagle tea tree is through behind the emerge in worm water, wash the wax of removing the surface of the seed by rubbing with the hands, at place backlight seed is covered in wherein on rebasing under with river sand or fine sand then, preserve moisture and stacked 30-60 days; Through stacking the planting seed swollen in ready-made spill seedbed, cover one deck fine earth again, cover with straw screen or mat or stalk behind the water-sprinkling; Seedtime is 7 to October, the coming year, late March was thrown off covering to April, the eagle tea seedling that sprouts is watered and fertilizing management, and the growth of seedling to that sprouts carried out the first time before and after the rainwater joint in 3 years transplants, and carries out the transplanting second time by the 5th year to decade.
