Abstract
The invention discloses a kind of methods for improving oleic acid content of peanuts, the method of the present invention passes through harvest peanut ahead of time, shorten the breeding time of peanut, the content of the oleic acid of common high-yield peanut can be made to effectively improve, than the normal harvest phase, the oleic acid content of peanuts of harvest is higher, maintain an equal level with the oleic acid content of high oleic acid peanut, and yield is significantly larger than the yield of high oleic acid peanut, reaches the peanut production economic benefit of high yield high oleic acid.Without waiting for high yield high oleic acid peanut varieties breeding, current high oleic acid and the incompatible problem of high yield just can solve using common high-yield peanut variety.
Description
Technical field
The present invention relates to peanut cultivation technical fields, and in particular to a method of improve oleic acid content of peanuts.
Background technique
Peanut is the main oil crops in China and industrial crops." during "the 10th five-years" " China's peanut average growth area is about
It 5000000 hectares, 14,000,000 tons of yield or so, ranks first in the world, accounts for 40% of Gross World Product or more.Peanut is that China is traditional
One of large agricultural product are exported, more than 100 country and earth mat, 77.8 ten thousand tons of annual export volume, about more than 600,000,000 dollars are exported to.For many years
Come, the Peanut and its products in China occupy an important position in the Peanut export trade and China's tools few in number
There is one of large variety of crops of the export-oriented industry of competitiveness in the international market.
Main fatty acid is oleic acid and linoleic acid in peanut, and linoleic acid is the basic reason for causing grease putrid and deteriorated.
In common peanut, the content of oleic acid is about 45%, and linoleic content is about 35%.Using common peanut as peanut made from raw material
Oil contains a large amount of linoleic acid, if not adding preservative agent, it is easy to putrid and deteriorated；If preservative is added, to human health
Have an adverse effect.Oleic acid can reduce the amount of blood total cholesterol and bad cholesterol, but not reduce the amount of good cholesterol.Battalion
Oleic acid is usually called " safe fats acid " by feeding boundary, and the content of oleic acid is to evaluate the one of the important signs that of edible oil quality.Nearly ten
In the past few years, peanut breeding worker improves the content of arachic acid by Breeding High-oil acid peanut.But one peanut of breeding is new
Kind needs 5 to 6 years time, takes a long time, and high oleic acid peanut yield it is low be peanut breeding a difficult point, how
Arachic acid is improved without reducing the research hotspot that peanut yield is current peanut breeding.Therefore, seek a kind of to improve peanut
The method of oleic acid content has important economic significance and social effect.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide it is a kind of improve oleic acid content of peanuts method, can be effective
Improve arachic acid.
To achieve the goals above, the present invention adopts the following technical scheme:
A method of oleic acid content of peanuts is improved, is included the following steps:
S1, high-yield peanut variety, sowing are selected；
S2, base manure is used sufficient；
S3, herbicide spraying in after planting 3 days；
S4, growth regulator was sprayed at Post flowering 30 days；
S5, do sth. in advance 10 days harvest peanuts than normal harvest time of the high-yield peanut variety.
It should be noted that the high yield that suitable south China peanut producing region rice field-upland field rotation field can be selected to plant is spent in step S1
Health product kind, in due course early sowing, it is ensured that full stand, for the producing region of the nearly tropic of cancer, spring planting is planted at the Waking of Insects (3rd solar term), can southward be done sth. in advance, past
North should suitably postpone.Fall planting is being planted around the beginning of autumn.
Further, in step S1, the seeding row spacing of sowing is 23 centimetres of 20 cm x, and 5 rows are planted, and every bunch planting 2 is sowed close
Degree is 1.8 ten thousand seedlings/mu.
Further, in step S1, the medicament of seed and carbendazim or Bravo is poured into together in small basin when sowing, is used
Power shakes up, and is attached to medicament on kind of skin, then seed is sown into soil.
Further, in step S1, when sowing, lays flat seed base-root or downwards, upward to avoid radicle.
Further, in step S2,500 kgs/acre of organic fertilizer, 5 kgs/acre of potassium chloride, 5~10 kgs/acre of urea,
Whole layer placement of fertilizer once uses sufficient.
Further, in step S3, the process of herbicide spraying are as follows: 0.15 kilogram of herbicide per acre is watered 100 kilograms
Even sprinkle is in furrow face.
Further, in step S4, the growth regulator concentration is 100 mgs/kg.
Further, tillage and weeding before blooming has the irrigation before flowering of irrigation conditions.
The beneficial effects of the present invention are:
The method of the present invention shortens the breeding time of peanut, can make the oleic acid of common high-yield peanut by harvest peanut ahead of time
Content effectively improve, than the normal harvest phase, the oleic acid content of peanuts of harvest is higher, oleic acid content with high oleic acid peanut
Maintain an equal level, and yield is significantly larger than the yield of high oleic acid peanut, reaches the peanut production economic benefit of high yield high oleic acid.Without etc.
To high yield high oleic acid peanut varieties breeding, current high oleic acid and high yield just can solve not using common high-yield peanut variety
The problem that can and deposit.
