Description

A kind of low yield tea plantation remodeling method

Technical field

The present invention relates to a kind of low yield tea plantation remodeling method.

Background technology

A lot of low yield tea plantation is had at south China, to comprise with stand structure be the tealeaves woods of pure forest, the tealeaves mixed forest being mixed with other seeds and tree vigo(u)r aging, variet complexity, line-break of being short of seedling are comparatively large, transform and be worth low tea place, these tea places have a strong impact on tea yield, therefore need to transform it.

Summary of the invention

The invention provides a kind of low yield tea plantation remodeling method.

The invention provides a kind of low yield tea plantation remodeling method, step is as follows: (1), cut and fill with clear assorted: surgery shrub and weeds to the tealeaves woods that stand structure is pure forest; Unless surgeried the tealeaves mixed forest being mixed with other seeds and filled with grass, cut down tealeaves trees; Combine simultaneously and cultivate again, remove tree head, bavin head and stone, mend tealeaves seedling;

(2), tree crown transformation: be applicable to that kind is relatively pure, density is high, the good tea place of basic condition, adopt deep pruning, heavy pruning for different tea places or deeply cut and carry out tree crown transformation;

(3), improve the soil, foster and apply fertilizer: namely carry out deep ploughing fertilizer after pruning, mu executes the 2000-3000 kilogram of fertilizer become thoroughly decomposed or 300 kilograms of oil cakes add 40 kilograms of Special composite fertilizer for tea again, fertilising more than ditch depth 30cm, and carry out staircase arrangement; Tea place after heavy pruning and deep pruning, plants rape, gardenful flower or other short bar legumes, or carries out littering covering between head 1-2;

(4), tree crown cultivates: the tea place after deep pruning or heavy pruning forbids to pluck, carry out sparse branching after the season of growth and prune in good time, again cultivating high yield tree crown, cut off sick branch, branch of growing thickly, overlapping branch, cultivate tree-like; Dark pruning tea place, when young sprout germination and growth is to a bud four, five leaves, carries out bud two, three leaf and plucks;

(5), replant to change and plant: be applicable to that tree vigo(u)r aging, variet complexity, line-break of being short of seedling are comparatively large, transformation is worth low low yield tea plantation; Deep pruning or heavy pruning are carried out to old tea place, deeply wide at old tea interline excavation is the plantation ditch of 50cm × 60cm, use sufficient base fertilizer, mu executes the 2000-3000 kilogram of fertilizer become thoroughly decomposed or 300 kilograms of oil cakes add 40 kilograms of Special composite fertilizer for tea again, again plants with 2 years asexual breeding tea shoots of life; Old tea place after deep pruning or heavy pruning is only adopted and is not supported, when newly planted tea field becomes garden, dig up old tea tree;

(6), prevention and elimination of disease and pests: the principle of adhering to " active prevention, integrated control ", do the prediction of damage by disease and insect well, once occur, prevent and treat in time.

After applying method of the present invention transformation, Second Year starts to be benefited, and producing tealeaves per year for every mu increases year by year.

Embodiment

Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is conventional method.

embodiment 1

Low yield tea plantation transformation should be selected to carry out at the end of spring tea, because growth of tea plant in summer is vigorous, is conducive to tree vigo(u)r and recovers and do not affect spring tea output in the coming year.Also can carry out after autumn tea terminates, at this moment transformation is conducive to increasing tea place ventilation and penetrating light, alleviate damage by disease and insect generation in the coming year, but the time is unsuitable too late, to avoid freeze injury.Concrete remodeling method is as follows:

1, filling is cut clear assorted: shrub and weeds are surgeried to the tealeaves woods that stand structure is pure forest; Unless surgeried the tealeaves mixed forest being mixed with other seeds and filled with grass, cut down tealeaves trees; Combine simultaneously and cultivate again, remove tree head, bavin head and stone, mend tealeaves seedling;

2, tree crown transformation: be applicable to that kind is relatively pure, density is high, the good tea place of basic condition, adopts deep pruning (liftoff 20cm), heavy pruning (liftoff 40-50cm) for different tea place or deeply cuts (liftoff 50-60cm) and carry out tree crown transformation;

3, improve the soil, foster and apply fertilizer: namely carry out deep ploughing fertilizer after pruning, mu executes the 2000-3000 kilogram of fertilizer become thoroughly decomposed or 300 kilograms of oil cakes add 40 kilograms of Special composite fertilizer for tea again, fertilising more than ditch depth 30cm, and carry out staircase arrangement.Tea place after heavy pruning and deep pruning, head 1-2 can between plant rape, gardenful flower or other short bar legumes, or carry out littering covering, reach improvement soil, increase the object of fertility;

4, tree crown is cultivated: the tea place after deep pruning or heavy pruning forbids to pluck, carry out sparse branching after the season of growth and prune in good time, again cultivating high yield tree crown, cut off sick branch, branch of growing thickly, overlapping branch, cultivate tree-like.Dark pruning tea place, when young sprout germination and growth is to a bud four, five leaves, can carries out bud two, three leaf and pluck;

5, replant to change and plant: be applicable to that tree vigo(u)r aging, variet complexity, line-break of being short of seedling are comparatively large, transformation is worth low low yield tea plantation.Can carry out deep pruning or heavy pruning to old tea place, deeply wide at old tea interline excavation is the plantation ditch of 50cm × 60cm, uses sufficient base fertilizer, again plants with 2 years asexual breeding tea shoots of life; Old tea place after deep pruning or heavy pruning is only adopted and is not supported, when newly planted tea field becomes garden, dig up old tea tree.

6, prevention and elimination of disease and pests: the principle of adhering to " active prevention, integrated control ", does the prediction of damage by disease and insect well, once occur, prevents and treats in time.

Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
