Description
Technical field
The present invention relates to agricultural plantation technology field, a kind of utilize oil tea leaf nutrient to judge dose
Method and application thereof.
Background technology
Oil tea (Camellia oleifera Abel.) is Theaceae (Theaceae) Camellia (Camellia) evergreen filling
Wood or dungarunga, be the distinctive woody oil tree species of China, big woody edible with Elaeis guineensis Jacq., Fructus oleae europaeae and Cortex cocois radicis the referred to as world four
Oilseed plant, its mature seed can be used to refine Oleum Camelliae, is a kind of green, the edible health-care oil of ecological and high nutrition, has " east
Olive oil " title, be the preferable edible oil of " three high " crowd, by FAO (Food and Agriculture Organization of the United Nation) (FAO) as emphasis promote strong
Health table oil.Additionally, Camellia olelfera Abel [C.oleosa (Lour.) Rehd. is the most gorgeous, the florescence (the 9-11 month) is on the occasion of few adolescence, great ornamental value；Meanwhile, oil
Tea or the extremely strong seeds of a contamination resistance, to the resistances such as sulfur dioxide, fluorine, chlorine, the great ecological value.For promoting oil
Tea industry develops, and the State Administration of Forestry has formulated " whole nation camellia oleiferaindustry development plan (2009-2020) " for 2009, to the year two thousand twenty
Plant 70,000,000 mu.At present, 250,000 mu of oil tea has been developed in Sichuan, to Regional Economic Development, promotes that peasant programme aspect is sent out
Wave the most important effect.But current oil tea produces that the most generally to there is fruit-setting rate low, yield poorly and unstable, its reason degasification
Outside time factor, the soil fertility that low level management causes is low and trunk infusion imbalance is one of the major reason of oil tea low yield.
Nutrition is growth and development of fruit tree, the basis of yield and quality raising, and nutrient is to affect fruit yield and quality
One of key factor.Leaf nutrition elementary analysis can accurately reflect the Condition of abundance or deficiency that tree is recuperated point, leaf nutrient analysis
It is one of important means of plant nutrient status evaluation with diagnosis.Sichuan Agricultural University is in 2012-2015, to Sichuan oil tea
The tea oil tree that oil tea garden, 52, normal region is carried out recuperate point status investigation and lot of experiments accumulation data information on the basis of, foundation
The variation amplitude of each constituent content of blade, feature, and consider that oil tea nutritional need characteristic determines oil tea Optimum range
Optimum range.New diagnostic method is provided for oil tea nutrition diagnosis, rectification nutritional deficiency and balance fertilizing.
Summary of the invention
It is an object of the invention to cause the dystrophic generation of fruit tree growth fairly common for blindly applying fertilizer in producing, make
Having become the improper underproduction of oil tea, change of production amplitude is big, also results in degradation problem under tree vigo(u)r, fruit quality, it is provided that a kind of utilization
Oil tea leaf nutrient judges method and the application thereof of dose, may determine that oil tea is applied fertilizer by measuring oil tea Leaf nutrient contents
The situation of amount.
For achieving the above object, the technical solution used in the present invention is: one utilizes oil tea leaf nutrient to judge dose
Method, including following steps in sequence:
(1) samples selection: set the sample ground of 4 20 × 20m in field to be measured, according to S type route, each on each sample ground
Select 5 strains as sampling tree；
(2) sampling: more than in the middle part of tree crown periphery, the current-year branch that growth selection is healthy and strong, respectively at east, south, west, north
4 directions gather mature leaf 20, seal and take back laboratory；
(3) processing: blade two sides wiped clean, remove petiole, complete under the conditions of weighing latter 100 DEG C 25min, then proceeds to
75 DEG C of constant temperature process 24h, again weigh, and load in sealing wide mouthed bottle standby after pulverizing 2mm sieve；
(4) element determination: claim leaf sample powder 0.3-0.4g to boil in disappearing and add concentrated sulphuric acid 5mL in pipe, places 10-12h, then adds double
Oxygen water 2mL, is placed in 300 DEG C and disappears and boil on stove, and the most every 30min drips 10 hydrogen peroxide, drip 3-4 time boil to disappearing liquid limpid after again
Heating 30min, after natural cooling, constant volume 50mL, transfers in plastic bottle standby；Offset the sample determination nitrogen after boiling, phosphorus, potassium,
Use Kjeldahl nitrogen determination nitrogen, use molybdenum antimony resistance colorimetric method to measure phosphorus, use flame spectrophotometric determination potassium；
(5) result judges: testing result and the comparison of the normal nutrient requirement rate of oil tea.
Further, the normal nutrient requirement rate of described oil tea is: N be 10.55-12.15g/kg, P be 0.65-0.72g/
Kg, K be 3.85-5.75g/kg, P/N be 0.059-0.062, K/N be 0.365-0.472.
The present invention also provides for a kind of method of judgement dose utilizing oil tea leaf nutrient answering in oil tea dose
With.
In the present invention, oil tea normal nutrient demand amount is that applicant lasts 4 years, to 52, oil tea normal region, Sichuan oil tea
On the basis of the regression relation of the many annual productions in garden and leaf nitrogen and phosphorus, potassium content is studied, the conclusion drawn.
The method have the benefit that: the rational application of fertilizer that the nutrient diagnosis method utilizing the present invention to propose is oil tea,
Formulate cultivation intensive management measure and scientific basis is provided, the disappearance of nutrient can not only be judged, and can judge between each nutrient
Equilibrium condition, thus reduce fertilising blindness, cost-effective, reduce the harmful effect to soil.Facts have proved and use this
The oil tea blade nutrient diagnosis method of bright offer, is balanced the oil tea garden of fertilising, and per mu yield increases by more than 33%, can effectively subtract
Little large and small annual production difference.
