Abstract

The present invention discloses a method for preventing and curing pomegranate fruit cracking, comprising the following steps of: step 1. after petals of a third pomegranate flower fall, spraying medicament on a first flower fruit and a second flower fruit in a fast-growing period, wherein the medicament comprises: 50-80 mg/L GA3, 0.1%-0.2% (w/v) CaCl2, and 0.2%-0.3% (w/v) KH2PO4; and step 2. spraying the medicament again in a young fruit growing period, wherein a time interval between the spraying for this time and the first time is 15 days, and spraying the medicament for a third time in a fruit color turning period, and the medicament sprayed for the second and third time is the same as that for the first time. The present invention is easy in operation, low in costs, and good in effect; is free from a production technical process such as bagging, and can reduce employment and material costs. The present invention can remarkably reduce an occurrence of fruit cracking in a pomegranate production process, thereby improving safe and high-efficient production of pomegranate fruit.

Description

A kind of method of preventing and treating pomegranate dehiscent fruit and occurring

Technical field

The present invention relates to Fruit Cracking Control Technology field, be specifically related to a kind of method of preventing and treating pomegranate dehiscent fruit and occurring.

Background technology

Pomegranate (Punica granatum L.) belongs to Punicaceae (Punicaceae) Punica (Punica L.) deciduous fruit tree.The polyphenoils such as flavonoid substances, pericarp tannic acid and Ellagitannins are rich in due to its fruit, there is antibacterium, anti-parasitism, the effect such as antiviral and anticancer, it is a kind of important nutrition and health care fruit, pomegranate also has important ornamental value simultaneously, therefore, pomegranate a kind ofly integrates ecology, economical, societal benefits, views and admires the excellent fruit tree (Zhou Guangjie with health care, Yuan Yongyong, Zeng Fanzhe etc., the current status and prospect prospect that China pomegranate produces, the agriculture journal in southwest, 1995,8 (1): 111-116).But pomegranate dehiscent fruit has become one of outstanding problem generally occurred in China's pomegranate planting area, all there is generation from young fruit period to fructescence dehiscent fruit phenomenon.Be easy to bacteria infection after fruit splits, thus cause fruit rot.Finally make its edibility and the large heavy discount of ornamental value, produce to pomegranate and bring about great losses.

The generation of pomegranate dehiscent fruit is normally caused by various composite factor.Especially in the intermediary and later stages that pomegranate fruit grows fast or expands, in fruit cell, substance accumulation and conversion are frequently.Now, seed expands rapidly, and in seed thick liquid cell, vacuole is comparatively large, short texture, and absorptivity is strong, and expansion rate is larger.And pericarp is thinning gradually, pericarp membrane is little and fine and close, and expansion rate is less, because its fibrillatable is inadequate, causes pericarp quality tender and crisp.If run into adverse weather, can induce and aggravate the generation of pomegranate dehiscent fruit.These bad external environments comprise, and heavy rain attacks, and there's a sudden fall in temperature, high temperature and drought etc.In addition, pomegranate kind itself with hereditary information be also its dehiscent fruit occur reason, easily there is dehiscent fruit in some kind, some is less generation then.Prevention and controls at present for pomegranate dehiscent fruit mainly concentrates the aspects such as orchard soil, water, fertile management and pruning fruit tree.But these measures drop into artificial many, and cost is high, length consuming time, and control dehiscent fruit generation limited efficiency.Utilize bagging measure to prevent and treat pomegranate dehiscent fruit in addition, bagging can alleviate the wound induced dehiscent fruit of external environment to fruit, can also improve fruit color and pulp quality etc. simultaneously.But bagging is time-consuming takes a lot of work, cost increases.Occur to better prevent and treat pomegranate dehiscent fruit, the present invention, on the basis strengthening pomegranate orchard soil, fertilizer, water management, directly sprays pomegranate fruit, obviously can reduce the generation of pomegranate dehiscent fruit.

Summary of the invention

The object of this invention is to provide a kind of method of preventing and treating pomegranate dehiscent fruit and occurring, to solve the technical barrier preventing and treating dehiscent fruit generation weak effect in pomegranate production process, thus improve the safe and efficient production of pomegranate fruit.

For solving the problem, the present invention by the following technical solutions:

Prevent and treat the method that pomegranate dehiscent fruit occurs, comprise the steps:

Step one, after petal comes off when pomegranate 3 flower, medicament is sprayed to the headdress flower fruit in fast growing period and 2 flowers and fruits: GA3+CaCl ₂+ KH ₂pO ₄;

Step 2, growth of young phase spray a medicine again, and this sprays and is spaced apart 15 days with first time, sprays third time medicament between fruit colour-change period again, and wherein, the medicament that second and third time sprays is identical with the medicament that first time sprays;

Step one and the concentration spraying each composition in medicament described in step 2 are: GA3,50 ~ 80mg/L; 0.1% ~ 0.2%(w/v) CaCl ₂; 0.2% ~ 0.3%(w/v) KH ₂pO ₄.

Beneficial effect of the present invention:

1, processing ease of the present invention, cost is low, effective; Significantly can reduce dehiscent fruit incidence in pomegranate production process, thus improve the safe and efficient production of pomegranate fruit.

2, the inventive method avoids bagging, can reduce recruitment and Master Cost.

Embodiment

Below in conjunction with embodiment, the present invention will be further described.Following embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and is all among protection scope of the present invention.

Prevent and treat the method that pomegranate dehiscent fruit occurs, it is characterized in that, comprise the steps:
