Abstract

The invention discloses a tea short-spike tender lateral branch cutting propagation method, comprising: the cultivation of spikes in mother tree orchard, establishing of nursery bed, cutting and seedling nursing. The cutting propagation method is characterized in that the spike cutting adopts the short-spike tender lateral branches. The cultivation method comprises the steps as follows: (1) more fertilizer is fertilized 10-15 days before spring tea; (2) after the spring tea is picked, the cutting is carried out immediately and foliar fertilizer which can prompt the growth of the buds is sprayed so as to prompt the buds to grow as mother spikes; (3) when the mother spikes grows with the depth of 30-50cm, the topping operation is carried out so as to prompt the lateral bud of the mother spikes to bourgeon; (4) when the lateral bud of the mother spike grows to become new tender lateral branches with the heights of 10-15cm, the spike cutting can be carried out. The tea short-spike tender lateral branch cutting propagation method has the advantages that under the condition of normal management, the survival rate reaches more than 95% and the seedling cutting rate reaches more than 90%; the seedling cutting time is short and requires only 6 months from cutting to seedling cutting, saves land renting expense and seedling nursing expense by more than 50% and improves the seedling cutting by more than 20%.

Description

Tea tree short sprout tender lateral branch cuttage

Technical field:

The present invention relates to the cutting propagation technology, specifically is tea tree short sprout tender lateral branch cuttage.

Background technology:

Domestic present improved tea variety cutting propagation technology is to take the single node cutting of the semi-lignified internode of a bud, a slice leaf, a joint 2.5～3cm.The standard of cutting fringe is the young sprout semi-lignified, and the blade maturation is cut the fringe cuttage when axillalry bud expands.The deficiency of this mating system is: because tea tree fringe bar axillalry bud exists difference, generally the axillalry bud by top expands soon (1), and seedling also looks fast during cuttage, the middle part axillalry bud takes second place, and the bottom axillalry bud is the slowest, and what have does not even expand, what have after the cuttage can grow young sprout, and what have can not grow, even look out, also be very weak, be easier to formation and only survive, can not go out the garden, the ratio that seedling accounts for is big, thereby outplanting rate is not high, and outplanting rate is about 50-70%; (2) it is long to go out the garden time, and about about 1 year, the worker employed in a plant nursery was many, the cost height.

Summary of the invention:

The objective of the invention is for overcoming the deficiencies in the prior art, and a kind of survival rate height is provided, goes out the tea tree short sprout tender lateral branch cuttage that the garden is fast, outplanting rate is high.

The object of the invention realizes by following technical proposals:

The present invention includes the cultivation in the female fringe of elite stand garden, adopt and execute before the spring tea heavy fertilely, carry out light pruning after adopting spring tea, set up the seedbed, the nursing of cuttage nursery stock, unlike the prior art be: plugged ear is short fringe tender lateral branch.

Described short fringe tender lateral branch, its structure is: the female fringe internode of semi-lignified of the long 2.5～3cm of a joint adds 1 climax leaves and adds a tender young sprout of side shoot that is about 10-15cm.

The breeding method of short fringe tender lateral branch comprises the steps:

(1) having adopted spring tea executed heavy fertile in preceding 10-15 days;

(2) prune immediately after having adopted spring tea, and spray the foliage fertilizer that promotes the bud-leaf growth, impel axillalry bud to grow up to female fringe;

(3) treat female spike length to 30-50cm, cut off a bud one leaf or two leaves and a bud, impel female fringe sprouting of lateral bud;

(4) when female fringe lateral bud length arrives the new tender lateral branch of 10-15cm, stay a slice climax leaves to carry out clip to this side shoot female fringe up and down, it is long to be 2.5-3cm, promptly obtains weak point fringe side spray plugged ear.

The invention has the advantages that:

(1) under the condition of normal management, survival rate reaches more than 95%, and outplanting rate reaches more than 90%;

(2) go out garden time weak point, only need 6 months to going out the garden, shorten seedling raise period about 6 months than domestic prior art from cuttage;

(3) with traditional mating system contrast, can save 50% land tenure expense and nursery stock nurse fees, outplanting rate improves more than 20%;

(4) also suitable other flowers cuttages of this method.

Embodiment:

(1) cultivate healthy and strong female fringe garden, female tea place age of tree required more than 2 years, and Fertilization Level is higher than produces more than one times;

(2) cultivate short fringe tender lateral branch:

Adopted light pruning behind the spring tea, impelled axillary bud sprouting to grow up to female fringe, female fringe young sprout is long long to 30cm, when terminal bud does not stop growing as yet, adopt a bud one leaf and pinch, when impelling sprouting of lateral bud to grow up to the new tender lateral branch of 15cm female fringe is stayed a slice climax leaves, between long section of 3cm, must lack fringe tender lateral branch skewer fringe;

(3) cut fringe:

The cuttage in July, tender lateral branch is long can cut fringe to 10cm, the cuttage in August, tender lateral branch is grown and is cut the fringe cuttage to 15cm, cuts the fringe time and is: before at 10 in the morning, after at 4 in afternoon, cut fringe with cutting the fringe method fast, cut preceding 5 days no pesticide growns of fringe and foliage fertilizer;

(4) the skewer fringe is handled:

Adopt the ABT root-inducing powder to handle, root-inducing powder is prepared in the previous day of cutting fringe.

(5) cutting time:

Removing hot weather should not be cuttage place during this period of time in 12 o'clock to 3 o'clock, but all cuttages of all the other times, but must be noted that, the unsuitable cuttage of the weather of following moderate rain or heavy rain, but cuttage behind the rain is drenched the seedbed as the too dried overnight of then answering in seedbed, so that cuttage in second day.

(6) seedbed is set up:

1. set up the frame that shades;

2. equipment of sprinkler irrigation is set, and nursery lot is ponding not, and soil ground must be acid soil;

3. nursery lot teds the soil in seedbed stand-by before cuttage;

4. before cuttage, carry out the seedbed and prepare (dredging ground, sterilization, fertilising, shop soil);

5. the nursery that subterranean water level is low is when doing the seedbed, and the height in seedbed is about 10cm, the nursery that subterranean water level is high, and the height in seedbed is about 20cm, width is 1.3-1.5 rice;

6. turtleback shape is combed in the seedbed that will ted, and basal dressing by every mu of sealing fertilizer 80-100 kilogram, repaves one deck loess above then, about the about 8cm of thickness, claps about the tight about 5cm in back;

7. shading screen is with 75% shading rate.

(7) nursery stock nursing:

1. want trickle at once after the cuttage, and to drench, preceding 10 days water sprays after cuttage will be on a small quantity repeatedly, hot weather with tea shoot not eave tile be advisable, generally be that 10 points, 12 points, 2 points, 4 respectively spray water one time, determine the number of times of water spray with Changes in weather, the number of times of will spraying water after 10 days reduces gradually, but that soil will keep is moistening;

2. nursery stock fertilising: treat that the most root of hairs of nursery stock reach 1.0cm left and right sides Shi Ke and execute fertilizer for the first time, for the first time based on urea, concentration is about 0.5%+0.1% composite fertilizers, executes once every about 10-15 days again, also can add some foliage fertilizers simultaneously when insect protected spray medicine.Seedling reaches the 20cm height and just stops fertilising when above, treats that spraying once-combined fertilizer again after nursery stock stops growing get final product, but must be noted that the intact fertilizer of each pouring all will spray clear water one time, the blade in case fertilizer is burnt.
