CN105432408A - Prevention and treatment method for preventing pomegranate fruit cracking - Google Patents

Abstract

The invention discloses a prevention and treatment method for preventing pomegranate fruit cracking. The method includes the following steps that soil water at the growth stage is reasonably controlled; plant diseases and pests are prevented from harming fruits; calcium is supplemented at the fruit expansion period; leaf fertilizer is supplemented in August; water is reasonably controlled in August and September, fruit cracking is avoided, and the fruits are harvested in time after being mature. Reasonable water control management, plant disease and pest prevention, leaf fertilizer supplementing and increase of the calcium level of the pomegranate fruits are adopted from the fruitlet period to the fruit ripening period, fruit cracking is avoided, the effect is remarkable, the pomegranate fruits are large in size and bright in color, and the yield is increased by about 20%.

Description

A kind of prevention and controls preventing pomegranate dehiscent fruit

Technical field

The present invention relates to planting technology field, be specifically related to a kind of prevention and controls preventing pomegranate dehiscent fruit.

Background technology

Pomegranate (formal name used at school: PunicagranatumL.) deciduous tree or shrub; Dan Ye, usually to giving birth to or clustering, without stipule.Hua Dingsheng or closely push up life, single raw or several cluster or form cyme, closely bell, sliver 5-9, petal 5-9, many gauffers, imbricate arrangement; Ovule is most.Berry is spherical, and top has place to deposit calyx lobes, and pericarp is thick; Seed is most, and berry is subsphaeroidal, the fructescence 9-10 month.Exosper meat is translucent, succulence; Secundine keratin.

Nature and flavor are sweet, sour and astringent, warm, have the effect such as desinsection, convergence, puckery intestines, only dysentery.Pomegranate fruit is nutritious, and Vitamin C content will exceed one or two times than apple, pears.

The history of Chinese cultivated pomegranate, tracks to Han dynasty, and recording according to Lu Gong is that Zhang Qian introduces from the Western Regions.There is cultivation in China north and south, comparatively large with ground cultivated areas such as Anhui, Jiangsu, Henan, and cultivates some kinds compared with high-quality.Wherein Anhui Huaiyuan County is the township of Chinese pomegranate, and " Huaiyuan pomegranate " is national geography sign protection product.

Fruit men are all known mostly; to gather this one-phase to maturation at pomegranate fruit expanding stage; pomegranate fruit, is easy to cracking, exposes at pomegranate seed; seed Prolonged exposure outside; be not subject to the protection of pericarp, the seed of fruit dehiscence part will be caused to turn black, affect outward appearance and sell; can fruit rot be caused time serious, and come off.

Summary of the invention

For solving the technical matters of above-mentioned run into pomegranate fruit cracking, orchard worker sums up a kind of prevention and controls preventing pomegranate dehiscent fruit through many years of experience, and concrete grammar is as follows:

Prevent a prevention and controls for pomegranate dehiscent fruit, be divided into following step:

conservative control keeps the moisture content in soil, in the 5-7 month in pomegranate fruit growth early stage, carry out interval 7-10 days and water a water, irrigation amount is every strain 30-50kg, keeps the moistening of soil, and after watering, cover grass or overlay film soil moisture conservation, if overcast and rainy more time, should drain the water away in time, grass or overlay film to be covered after rain, be incubated in order to temperature control;

in the first tenday period of a month in the last ten-days period in July to August, at pomegranate fruit calyx, the absorbent wool soaked by 20-30mg/l Gibberellins solution is sticked at hollow place, sprays fruit surface simultaneously;

in the first tenday period of a month in August, fruit expanding period, the calcium chloride water of 1% is sprayed in fruit face, once in a week, sprays 3 times continuously, and stops watering, and improves pericarp toughness and anti-crack ability;

in the middle ten days in August, weather calm when 17, tree body sprays 0.5% aqueous solution of urea, once in a week, sprays 4 times continuously;

in the Pomegranate Growth later stage in 8-9 month, stop watering, and in time get rid of unnecessary ponding in gardens, keep soil moisture moderate, prevent fruit because of the moisture of hyperabsorption dehiscent fruit;

before young fruit period bagging, fruit face is sprayed 20% and is killed chrysanthemum emulsifiable concentrate 2000 times of liquid, eliminates the damage by disease and insect such as pomegranate fruit germ and dichocrocis punctiferalis, during fruit maturation, gathers in time, prevents because absorbing excess moisture, face spalling pericarp.

Beneficial effect of the present invention: adopt young fruit period when fruit maturation, reasonable water control pipe reason, preventing disease and pest, supplement foliage fertilizer, increase the calcium content of pomegranate fruit, prevent fruit from splitting, Be very effective, and pomegranate fruit is individual large, lovely luster, rate of growth about 20%, for friend orchard worker improves income.

Embodiment

Prevent a prevention and controls for pomegranate dehiscent fruit, be divided into following step:

conservative control keeps the moisture content in soil, in the 5-7 month in pomegranate fruit growth early stage, carry out interval 7-10 days and water a water, irrigation amount is every strain 30-50kg, keeps the moistening of soil, and after watering, cover grass or overlay film soil moisture conservation, if overcast and rainy more time, should drain the water away in time, grass or overlay film to be covered after rain, be incubated in order to temperature control;

in the first tenday period of a month in the last ten-days period in July to August, at pomegranate fruit calyx, the absorbent wool soaked by 20-30mg/l Gibberellins solution is sticked at hollow place, sprays fruit surface simultaneously;

in the first tenday period of a month in August, fruit expanding period, the calcium chloride water of 1% is sprayed in fruit face, once in a week, sprays 3 times continuously, and stops watering, and improves pericarp toughness and anti-crack ability;

in the middle ten days in August, weather calm when 17, tree body sprays 0.5% aqueous solution of urea, once in a week, sprays 4 times continuously;

in the Pomegranate Growth later stage in 8-9 month, stop watering, and in time get rid of unnecessary ponding in gardens, keep soil moisture moderate, prevent fruit because of the moisture of hyperabsorption dehiscent fruit;

before young fruit period bagging, fruit face is sprayed 20% and is killed chrysanthemum emulsifiable concentrate 2000 times of liquid, eliminates the damage by disease and insect such as pomegranate fruit germ and dichocrocis punctiferalis, during fruit maturation, gathers in time, prevents because absorbing excess moisture, face spalling pericarp.
