CN106359075A - Method of increasing fruit setting rate of pomegranates through artificial pollination - Google Patents

Abstract

The invention relates to a method of increasing fruit setting rate of pomegranates through artificial pollination. The method includes the steps of: 1) spray application of a fertilizer pesticide on leaves; 2) artificial pollination; 3) management during blossom and fruiting period; and 4) prevention and treatment against diseases and insect pests. The method can improve growth of flowers and fruits by spray-applying the fertilizer pesticide during blossom stage of the pomegranate, thereby preventing bacterial infection and improving the fruit setting rate of the pomegranate; through the artificial pollination, a problem of low fruit setting rate in self-pollination is solved; in the management during blossom and fruiting period, fruits in disease are removed, and nutrition is concentrated and fruit quality is improved; and through the prevention and treatment against diseases and insect pests, yield and the fruit setting rate are further improved.

Description

A kind of method that artificial pollination improves Punica granatum L. fruit-setting rate

Technical field

The invention belongs to Punica granatum L. field of planting and in particular to a kind of artificial pollination improve Punica granatum L. fruit-setting rate method.

Background technology

Punica granatum L. deciduous tree or shrub；Dan Ye, usual opposite or cluster life, no stipule.Flower basidixed or nearly basidixed, single raw or several Piece cluster is raw or composition cyme, closely bell, sliver 5-9, petal 5-9, many gauffers, and imbricate arranges；Ovule is most.Berry ball Shape, there is persistent calyx sliver on top, and peel is thick；Seed is most, and berry is subsphaeroidal, the fructescence 9-10 month.Episperm meat is semi-transparent Bright, succulence；Endotesta keratin.

Punica granatum L. is nutritious, containing a large amount of vitamin cs, organic acid, saccharide, protein, fat, vitamin and calcium, phosphorus, The mineral such as potassium, have functions that heat clearing away, removing toxic substances, suppressing the hyperactive liver, enrich blood, invigorate blood circulation and antidiarrheal.

Due to lacking scientific management, hold inaccurate particularly in the links such as fertilising, fruit retention, Punica granatum L. fruit-setting rate is low, Punica granatum L. Orchard yield is relatively low.

Content of the invention

It is an object of the invention to provide a kind of method that artificial pollination improves Punica granatum L. fruit-setting rate, comprise the following steps:

(1) fertilizer for spraying on leaf surface medicine: in Punica granatum L. initial bloom stage, spraying agent 2-3 time, time interval is 15 days；10ml/l gibberellins+ 200 times of liquid+0.2% urea liquid+1% calcium superphosphate leachate+0.2% di(2-ethylhexyl)phosphates of 50% 800 times of carbendazim liquid+40% new high fat film Hydrogen potassium solution；

(2) artificial pollination: a large amount of collections will be opened or the unnecessary normal type just opened and middle type flower bud and flower from pollinizers, removes Petal, takes out flower pesticide, is placed on the place be dried, divulge information, having light to dry, makes anther dehiscence, then Fructus Forsythiae is placed in exsiccator It is placed in refrigerator and preserves, during pollination, dip pollen point on the stigma of open tubular flower with brush pen；

(3) flowers and fruits period management: proceed by thin flower bud when can go out mitriform flower and tubular flower respectively from alabastrum and terminate to the florescence, extract 70% mitriform alabastrum；Main extract malformed fruit, there is the fruit of disappearance in disease pest fruit, fruit face, next removes double fruits, cluster fruit, each other Close overstocked fruit, stays fruit according to 20-25 centimetre on the Fruit branch standard staying 1 Punica granatum L.；When tubular flower is completely open, to holder portion Gibberellins solution concentration 5-10ml/l is sprayed in position, carries out for 2-3 time protecting flower；

(4) prevention and control of plant diseases, pest control: main inclusion Punica granatum L. dry rot, brown spot, dichocrocis punctiferalis, internal lobe moth, cnidocampa flavescens walker, described Punica granatum L. dry rot Disease and brown spot can remove dry mummy under disease carrying germ bark and tree in winter-spring season, burn or buried, are aided with and scrape bark, lime water Whitewash；Described dichocrocis punctiferalis employing can adopt 50% phoxim or 90% metrifonate 0.1% solution, the ovum worm incubation period each 7 Its spraying once, is prevented and treated for continuous 2 times；Described internal lobe moth, cnidocampa flavescens walker can spray 90% metrifonate 600-800 in Larvae occurrence time Times liquid is prevented and treated.

The invention has the beneficial effects as follows: the present invention plays promotion flowers and fruits in Punica granatum L. Spraying in the flowering stage fertilizer medicine and grows, pre- preventing germs infection, Improve Punica granatum L. fruit-setting rate；By artificial pollination, it is to avoid self-pollination fruit-setting rate low problem, by blooming period management, remove disease Really, concentrate nutrition, improve fruit；Prevent from improving yield and fruit-setting rate further by pest and disease damage.

Specific embodiment

The present invention is described in further details with specific embodiment with reference to embodiment.
