Abstract

The invention discloses a method for producing a superoxide dismutase Dangshan pear. According to the method, the superoxide dismutase is sprayed on flowers or leaves of the Dangshan pear in four periods, namely fruitlet expanding period, fruit quick expanding period, period before bagging and period before picking, so that the superoxide dismutase is enriched in the Dangshan pear fruits. The method has simple and convenient operation, and the produced Dangshan pear has the advantages of rich nutrition, yellow and bright color, small kernel, big fruit and regular shape.

Description

A kind of production method of superoxide dismutase Dangshan pear

Technical field

The present invention relates to the planting fruit trees field, specifically is a kind of production method of superoxide dismutase Dangshan pear.

Background technology

SOD is the abbreviation of hepatocuprein (Superoxide.Dismutase), is naturally occurring superoxide radical transforming factor in organic object.One of it and peroxide dismutase (POD) and catalase (CAT) are formed a complete deoxygenation chain.Therefore the international biochemical committee and U.S. food management board claim that SOD is " the anti-ageing factor " " beauty treatment favourite son ".The approved SOD of China Ministry of Public Health is the functional materials that delays senility.Domesticly series of products have been developed in fields such as cosmetics, nutriment.The functional nutrient fruit is is also researched and developed successively and is put into production.

Summary of the invention

The invention provides a kind of production method of superoxide dismutase Dangshan pear; Be on the pear flower of Dangshan pear or pear tree blade face, to spray superoxide dismutase the period of producing in the difference of Dangshan pear; Make enrichment superoxide dismutase in the Dangshan pear, the Dangshan pear of being produced is nutritious, yellow and bright color, core is little, fruit is big, fruit shape is rectified.

Technical scheme of the present invention is:

The present invention passes through before the rapid expanding stage of young fruit expanding stage, fruit of Dangshan pear plantation, bagging, plucks the preceding superoxide dismutase that sprays, and makes Dangshan pear enrichment oxide mutase, has the nutritional character of oxide mutase; And remove crisp pears sepal through spraying fertilizer, initial bloom stage spray Du Pont lucky star, dredge the flower bud flower thinning before spending, lay reflex film, cover grass, cover bag technique, manual work, the technological integrated application of physical method prevention and elimination of disease and pests in the ranks; Handling crisp pears soluble solid is 11.8%, increases by 0.8% than conventional garden, nutritious, the yellow and bright color of the Dangshan pear of being produced; Core is little; Lithocyte is few, and sepal comes off entirely, and fruit shape is rectified; The fruit regularity is good, has reached the requirement of functional nutrient fruit outward appearance and interior quality.

Embodiment

The production method of superoxide dismutase Dangshan pear:

Establish 4 processing altogether, dilute liquid medicine evenly sprays with motor-driven farm chemical spray pump; Spray date is before young fruit expanding stage, the rapid expanding stage of fruit, the bagging, sprays altogether 4 times before the harvesting.

The concrete time is:

July 12 first time; For the second time: August 15; The 3rd September 8; The 4th September 19.

Handle one: every mu 325 gram, divide to spray for 4 times; Consumption is followed successively by 100 grams, 75 grams, 75 grams, 75 grams.Each mu adds 400 kilograms of sprayings of water with amount of medicament;

Handle two: every mu 260 gram, divide to spray for 4 times; Consumption is followed successively by 80 grams, 60 grams, 60 grams, 60 grams.Each every mu adds 400 kilograms of sprayings of water with amount of medicament;

Handle three: every mu 195 gram, divide to spray for 4 times; Consumption is followed successively by 60 grams, 45 grams, 45 grams, 45 grams.Each every mu adds 400 kilograms of sprayings of water with amount of medicament;

Handle four: do not spray the SOD medicine.

Supporting technology:

No matter the functional nutrient fruit is from still on interior quality, all representing high production technology level and high-tech content in appearance.The standardized production administrative skill is all adopted in the orchard management, and six guardian technique measures of integrated application guarantee that the SOD Dangshan pear reaches nutrition, safety, health care function.

1, applying organic manure sprays foliage fertilizer

For the fruit inclusion is improved, we have selected for use Shanghai to join " Gu Lin " board fertilizer that industry biological products Co., Ltd produces, every strain 25kg, strip ditch spread at twice.

2, sepal removes technology

For fruit shape is rectified, remove crisp pears sepal, 8000 times of initial bloom stage spray Du Pont lucky stars.

3, flower and fruit thinning

In order to make fruit neat, improve the high quality fruit rate, dredge the flower bud flower thinning before spending, young fruit period is dredged disease, worm, malformed fruit to remove, and stays really by the strictness of 20cm spacing, guarantees that the high quality fruit of leaving and taking grows.

4, lay reflex film is covered grass in the ranks

For increasing soil organic matter content, cover plantation clover in the ranks, not only increased the content of organic matter, also protected natural enemy simultaneously; Cover the silvery reflection film under the tree crown projection, increase ground return light, make each position of tree crown even light, optimized the growing environment of crisp pears, color and fineness obviously improve.

5, cover bag technique

According to research, the SOD enzyme absorbs through blade.Pollution-free for the SOD the operatic circle that makes production, meet the requirement of nuisanceless fruit, each is handled and has established the bagging processing.

6, artificial, physical method prevention and elimination of disease and pests technology

This test region takes a series of physics, biology, artificial means such as yellow plate trapping, desinsection lamp, spray biomembrane, extension gyplure to carry out prevention and elimination of disease and pests, and selects low toxicity and low residue medicament science prevention and control damage by disease and insect for use.

Through the integrated application of above six kinds of measures, the crisp pears soluble solid after the processing is 11.8%, increases by 0.8% than untreated crisp pears soluble solid; Yellow and bright color, core is little, and lithocyte is few; Sepal comes off entirely; Fruit shape is rectified, and the fruit regularity is good, has reached the requirement of functional nutrient fruit outward appearance and interior quality.

Enzymic activity content statistics to the Dangshan pear after four kinds of processing:

Three kinds of treatment enzyme activity reach 34.3 respectively; 31.1; 29.0; All be significantly higher than untreated 12.0; Handle 1 and be higher than contrast 185.8%, be 2.86 times of contrast.
