Description
Technical field
The present invention relates to oil tea planting technology field, especially a kind of flower and fruit protecting improves the oil tea implantation methods of yield.
Background technology
Oil tea is seed oil content highest in Theaceae Camellia, and the oil species with higher productive value,
It is the important woody oleiferous plants industrial crops in southern area, also known as tea oil tree or tea seed tree.The high 4-6m of oil tea plant, often in 2-
3m.Oil tea well developed root system, impoverishment tolerant soil, Adaptable growth scope is wide, and marginal land can be made full use of to grow, and is economic benefit
In the excellent another name for Sichuan Province having both with both ecological benefits, in its oil plant prepared, unsaturated fatty acid content is up to more than 90%, much
Higher than the content of unrighted acid in high-quality olive oil.The main component of tea oil is oleic acid and linoleic acid, while is also contained
The high price such as a small amount of leukotrienes unrighted acid, vitamin A and vitamin E.Tea oil, also with preferable health care and medical work(
Can, wherein the beneficiating ingredient contained is easily absorbed by the body, be eaten for a long time for reduce human serum cholesterol possess it is more significant
Effect, while also have the special efficacy for preventing and treating angiocardiopathy, the possibility of the artery sclerosis of people can be alleviated, especially
It is that leukotrienes has the effect of softening blood vessel, reduction blood fat and nourishing are refreshed oneself.
Oil tea flower and fruit protecting is the new tool used in recent years to improve tea-oil tree yield to attempt；In the prior art, in order to
So that oil tea realizes flower and fruit protecting, tea-oil tree yield is improved, usually using hormone medicine, such as gibberellin, 2.4-D, 92 O, Yin
Indolylbutyric acid, indolebutyric acid etc., although it can improve tea-oil tree yield, easily cause medicament residue, influence oil tea quality, it is dirty
Environment is contaminated, and because processing mode of the prior art is incorrect, causes tea-oil tree yield to improve limited.
In consideration of it, someone is studied oil tea planting process so that thoroughly removes oil tea flowers and fruits within first 3 years after afforestation；
From afforesting the 5th year, annual mid-October-mid-December, sprayed in oil tea initial bloom stage and protect flower pesticide agent, and at fine day or cloudy day
Tree crown is sprayed, twice in succession, interval is 7 days；From afforesting the 5th year, annual mid-April-mid-May, come in tea fruit expanding stage
Sprinkling fruit retention before facing, and tree crown is sprayed in fine day or cloudy day, twice in succession, interval is 7 days；Tea tree root is chased after
Winter top dressing or base manure, it is protected boron fertilizer H3B03,0.3% potassium dihydrogen phosphate and the clear water that flower pesticide agent is 0.2% and presses 2:3:1000 weight
It is made than fully mixing well；The fruit retention be 0.3% potassium dihydrogen phosphate, 0.5% urea and 0.2% zinc sulfate, clear water according to
3:5:2:1000 weight is made than fully mixing well, and winter top dressing or base manure are decomposed tea seed cake cake fertilizer 5kg and N P and K active ingredient
Content is 48% composite fertilizer 1kg so that tea-oil tree yield and oil tea quality are improved, middle compared with the prior art to use hormone
The output increased that class medicine is handled oil tea 30-40%, still, due to being sprayed every time with fruit retention to protecting flower pesticide agent
The control of the relative amount of amount and material composition is incorrect, still causes tea-oil tree yield not reach perfect condition.
Based on this, this researcher is directed to above-mentioned technical problem, in oil tea planting process, guarantor's flower pesticide agent of use, and fruit retention
The material composition relative amount of medicament is adjusted and controlled, and combines the control of sprinkling process so that tea-oil tree yield obtains
It is greatly improved.
The content of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of flower and fruit protecting and improves yield
Oil tea implantation methods.
It is achieved particular by following technical scheme：
A kind of flower and fruit protecting improves the oil tea implantation methods of yield, comprises the following steps：
（1）Thoroughly remove oil tea flowers and fruits within first 2 years after afforestation；
