Abstract

The method that Nanguo pear fruit takes off calyx rate is improved the invention provides a kind of, in full-bloom stage, all flowers are sprayed with PBO200 times of liquid, in the fallen flowers phase, all young fruits are squirted with 200 times of liquid of calcium boron mixed solution；PBO200 times of liquid is the ratio for adding 200ml clear water in 1g PBO, and PBO dissolvings are formulated；200 times of liquid of calcium boron mixed solution are by 1g CaCl₂, 1g boric acid add the ratio of 200ml clear water, by CaCl₂It is formulated with boric acid dissolving.What the present invention was provided improves the method that Nanguo pear fruit takes off calyx rate, respectively the full-bloom stage in pear cv nanguo and fallen flowers phase, floral organ is sprayed with special chemical reagent respectively, not only increase the de- calyx rate of fruit, and Stone cell content is reduced, improve the inside and outside quality of fruit.

Description

It is a kind of to improve the method that Nanguo pear fruit takes off calyx rate

Technical field

Calyx method is taken off the present invention relates to a kind of fruit, more particularly to a kind of method for improving the de- calyx rate of Nanguo pear fruit.

Background technology

Nanguo pear fruit such as has pulp exquisiteness, soft and succulency, given off a strong fragrance at the various features.In pear cultivation, fruit calyx It is common a kind of phenomenon in fruit development that piece, which is harbored, and it is higher that the sepal of pear cv nanguo harbors fruit ratio.Sepal, which is harbored, to be caused Fruit surface is coarse, color and luster is dimmed, pulp is thicker, lithocyte increasing number and the sugar content of fruit decline, and causes fruit quality to become It is bad.Pear fruit takes off calyx method, and to include manually de- calyx and chemical reagent de-, and manually de- calyx has that labor intensity is larger, and labour cost is high The problem of, though existing chemical reagent can improve de- calyx rate, the operatic circle quality and tree vigo(u)r can also be had adverse effect on.Institute In the urgent need to one kind can improve de- calyx fruit rate, the practical technique of fruit quality can be lifted again and is harbored to solve fruit sepal The problem of.

The content of the invention

The method that Nanguo pear fruit takes off calyx rate is improved it is an object of the invention to provide a kind of, while fruit product can be lifted Matter.

Technical scheme is as follows：It is a kind of to improve the method that Nanguo pear fruit takes off calyx rate, in full-bloom stage, use PBO200 Times liquid sprays all flowers, and in the fallen flowers phase, all young fruits are squirted with 200 times of liquid of calcium boron mixed solution；PBO200 times of liquid is by 1g PBO adds the ratio of 200ml clear water, and PBO dissolvings are formulated；200 times of liquid of calcium boron mixed solution are by 1g CaCl₂, 1g boric acid Plus the ratio of 200ml clear water, by CaCl₂It is formulated with boric acid dissolving.

Wherein, during above-mentioned full-bloom stage refers to 75% flowering, during the fallen flowers phase refers to the decline of 75% flower.

The present invention has the advantages that：

What the present invention was provided improves the method that Nanguo pear fruit takes off calyx rate, full-bloom stage and fallen flowers phase in pear cv nanguo, difference Flower and young fruit are sprayed with special chemical reagent, the de- calyx rate of fruit is effectively increased, and reduces Stone cell content, is lifted The inside and outside quality of fruit, it is simple to operate, labour cost is reduced, improve economic benefit.

Embodiment

The embodiment of the present invention is described in further detail with reference to embodiment.

Embodiment

The present embodiment is carried out in Agricultural University Of Shenyang's fruit tree Experimental Base.

1. the preparation of de- calyx reagent

The preparation of the PBO aqueous solution

Add the ratio of 200ml clear water according to 1g PBO, PBO is dissolved, be configured to the PBO aqueous solution.

The preparation of calcium boron mixed solution

According to 1g CaCl₂, 1g boric acid add the ratio of 200ml clear water, by CaCl₂With boric acid dissolving, the mixing of calcium boron is configured to Solution.

2. the time of implementation and method

In pear cv nanguo pear flower full-bloom stage, the whole flowers of pear tree are squirted with 200 times of the PBO aqueous solution, fall after 75% Florescence is again squirted the whole young fruits of pear tree with 200 times of calcium boron mixed solution.

3. the measurement result of de- calyx rate and fruit quality

30 days after fallen flowers, calyx rate is taken off to fruit and the index of quality (single fruit weight, soluble solid, Stone cell content etc.) is entered Row investigation statisticses, and with blank test and individually spray PBO experimental conditions and contrasted, it is as a result as shown in table 1 below.

The pear cv nanguo of table 1 takes off calyx result statistical form

According to investigation result as can be seen that spraying 200 times of PBO solution in full-bloom stage, and falling the mixing of Spraying in the flowering stage calcium boron The combination of 200 times of liquid, the Nanguo pear fruit not dealt with can be taken off calyx rate bring up to 98%, Stone cell content reduction by 62% 21.1%, soluble solid improves 24.4%, takes off calyx effect significantly, and can effectively lift fruit quality.With PBO is used alone Compare, combined treatment can effectively reduce Stone cell content, and single fruit weight and soluble solid increase.

It is participation, the process mutually cooperateed with jointly such as fruit endogenous hormones and cell wall degrading enzyme that sepal, which comes off,.Pears full blossom 6-12d is the critical period that fruit sepal comes off afterwards, during this period, IAA and GA in sepal and core₃Content height is conducive to sepal Harbor, ABA contents height is conducive to sepal to come off in sepal.

PBO is a kind of mixing powder being made up of uniconazole P, the basic element of cell division, auxin derivative etc., is a kind of function More complete compound fruit tree nutrition and growth regulator.In production practices, PBO, which is used alone, can also play promotion the operatic circle The effect that real sepal comes off, but Stone cell content can be increased, quality decline.

The operatic circle lithocyte is formed by one kind on its primary wall deposits lignin etc. as parenchyma cell, and wooden The formation of element has important relation with boron, Ca supply level.Boron is mainly by influenceing the enzymatic activity related to lignin synthesis To influence it to be formed.Boron can promote the transport of sugar, suppress to use root in the formation of lignin precursor aldehydes matter, therefore production Outer topdress carrys out the plain nutrition of boron make-up, to improve the quality of fruit.Calcium participates in the regulation of secondary wall, and direct shadow is formed with to lithocyte Ring.Research has shown that spraying calcium on the leaf can reduce the tannin content of pear fruit, soluble pectin content, Stone cell content, improves single fruit Weight, the hardness of fruit, soluble solid.Young fruit period is the critical period of pear fruit lithocyte development.So, sprayed in this period Calcium boron mixed solution can effectively control Stone cell content, improve fruit quality.Full-bloom stage and fallen flowers of the present invention in pear cv nanguo Phase, all flowers are sprayed with PBO200 times of liquid respectively, in the fallen flowers phase, squirt all young fruits with 200 times of liquid of calcium boron mixed solution, have Effect improves the de- calyx rate of fruit, and reduces Stone cell content, improves the inside and outside quality of fruit, simple to operate, cost is low.
