Embodiment 1

[0019] 1. Select the orchard of the Daqingpi sweet pomegranate variety with the same site conditions, select 9 trees for spraying the agent, 9 trees as a control, and count the occurrence of fruit cracking before the fruit is picked. The number of cracked fruits / total number of fruits represents the occurrence of fruit cracking. The statistics of the fruit cracking rate of the three trees are treated as a repeat, repeating three times in total;

[0020] 2. When the petals of the pomegranate 3 flowers fall off, spray the medicament: GA3, 50mg / L; 0.1% (w / v) CaCl 2 ; 0.2% (w / v) KH 2 PO 4 ;

[0021] 3. Spray the medicine again during the growth period of the young fruit. The interval between this spray and the first time is 15 days. During the fruit color change, spray the third medicine again. The second and third sprays are the same as the first time.

[0022] In this example, the occurrence rate of fruit cracking in the control group was 30.5%±6.5% (mean ± standard error), and after s...

Embodiment 3

[0029] 1. Choose a pomegranate variety orchard with the same site conditions, select 9 trees for spraying, and 9 trees as a control. The incidence of fruit cracking is counted before the fruit is picked. The number of cracked fruits / total number of fruits represents the incidence of cracking. The statistics of the fruit cracking rate of the three trees are treated as a repeat, repeating three times in total;

[0030] 2. After pomegranate 3 flower petals fall off, spray the agent: GA3, 80mg / L; 0.2% (w / v) CaCl 2 ; 0.3% (w / v) KH 2 PO 4 ;

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

Technical field [0001] The invention relates to the technical field of prevention and control of fruit cracking, in particular to a method for preventing pomegranate cracking. Background technique [0002] Pomegranate (Punica granatum L.) belongs to the deciduous fruit tree of the pomegranate family (Punicaceae) of the genus Punica (Punica L.). Because its fruit is rich in flavonoids, peel tannins and ellagitannins and other antioxidants, it has anti-bacterial, anti-parasitic, anti-virus and anti-cancer effects. It is an important nutritious and health-care fruit. It has important ornamental value. Therefore, pomegranate is an excellent fruit tree that integrates ecological, economic, social benefits, ornamental and health care functions (Zhou Guangjie, Yuan Yongyong, Zeng Fanzhe, etc., Current status and development prospects of pomegranate production in China, Southwest Agricultural Journal , 1995, 8(1): 111-116). However, pomegranate fruit cracking has become one of the prom...
