Description

A kind of method utilizing edible alkali and river sand to carry out Idesia polycarpa seed treatment

Technical field

The present invention relates to agricultural breeding field, particularly to a kind of method utilizing edible alkali and river sand to carry out Idesia polycarpa seed treatment.

Background technology

Idesia polycarpa (formal name used at school: IdesiapolycarpaMaxim.var.vestitaDiels) is the deciduous tree that Flacourtiaceae Radix seu Cortex Malloti nepalensis belongs to, the subtropical zone positive quick growing species of trees, its key property has: fruit oil content is high, oil quality is high, commercial development is worth greatly, the edible oil of high-quality can be produced, be also the excellent raw material extracting linoleic acid, vitamin, preparation biodiesel and senior lubricant; Meanwhile, Idesia polycarpa is also excellent ornamental tree species, so having bigger economic worth and the ecological value.

Although Idesia polycarpa is distributed more widely, but owing to it belongs to Flacourtiaceae, natural germination percentage is relatively low, thus causing stock number less. Therefore, only its breeding of germinateing of reliable human assistance, is just provided that substantial amounts of Idesia polycarpa resource is for commercial application.

At present, in order to improve germination percentage and the planting percent of Idesia polycarpa seed, reducing seedling sickness rate, the Idesia polycarpa method for treating seeds reported mainly has: (1) add river sand carry out crumpling, wash wax after sow, such as China's application that application number is 200810148048.1; (2) with nursery after potassium dihydrogen phosphate, sodium bicarbonate solution immersion seed, if application number is the Chinese patent application of 200910059408.5.

Above-mentioned method for treating seeds, although yet suffering from that percentage of seedgermination is higher but problem that sickness rate is also higher, 200810148048.1 patent applications described above, although or seed sickness rate is relatively low but problem that germination percentage is relatively low again, 200910059408.5 patent applications described above. It addition, above-mentioned method for treating seeds, the fruit oil content obtained is relatively low, the oil content of dry full fruit, is typically in about 40% so that its economic worth is relatively low.

Summary of the invention

The goal of the invention of the present invention is in that: provide the method for treating seeds of a kind of new Idesia polycarpa nursery, with the problem solving above-mentioned germination percentage, planting percent and oil content.

The technical solution used in the present invention is such that a kind of method utilizing edible alkali and river sand to carry out Idesia polycarpa seed treatment, comprises the following steps:

(1), Idesia polycarpa seed is first soaked in water, then pulls out;

(2) the ratio addition edible alkali of 4-6 gram of edible alkali, is added according to 1 kilogram of Idesia polycarpa seed, and add river sand according to the ratio that Idesia polycarpa seed and river sand mass ratio are 1:0.8～1:1.2, carry out dry stranding after then described Idesia polycarpa seed, edible alkali and river sand being mixed;

(3), warm water carries out rubbing washing again after dry stranding 3～5min, and the degree rubbing washing is that Idesia polycarpa seed is matt, and the wax coat on surface is destroyed; Seed mix after process cleans up with 30～35 DEG C of warm water again, is then sown into seedbed with warm water soaking after 6～12 hours and carries out seedling culture.

The object of the present invention is achieved like this: carries out dry stranding after the Idesia polycarpa seed just leached after immersion adds appropriate edible alkali and the mixing of a certain proportion of river sand, then add water and carry out rubbing washing, it is more beneficial for the destruction of the wax layer on its surface, thus being conducive to moisture to enter in seed, it is ensured that the germination percentage of seed; Simultaneously the toxicity of edible alkali is relatively low, consumption is few, can alleviate the injury to seed and the potential injury to its seedling respectively, can reduce the sickness rate of seedling, it addition, adopt in this way, can be effectively improved the oil content of mature fruit while ensureing relatively high germination rate. Wherein, described edible alkali be mainly composed of sodium carbonate, described river sand particle diameter is 35 order-45 order preferably.

As preferred technical scheme, in step (1), soak time is 12～24h.

As preferred technical scheme, in step (2), the amount adding edible alkali is that 1 kilogram of Idesia polycarpa adds 5g edible alkali.

As preferred technical scheme, in step (2), the river sand of addition and the mass ratio of Idesia polycarpa are 1:1.

As preferred technical scheme, in step (3), the temperature of described warm water is 30～35 DEG C.

In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: the present invention determines for the composition of the edible alkali of seed treatment, consumption is few, can accurately be controlled, it is simultaneously introduced river sand to carry out rubbing washing, it is more beneficial for the destruction of Idesia polycarpa wax coat, can guarantee that the germination percentage of healthy seed is more than 99%, seedling sickness rate is less than 1% simultaneously, planting percent is more than 98.5%, additionally, cultivate the oil content of the ripe dry fruit obtained, more than 46% can be reached, economic worth is high, and it is absent from the limiting factor grown saplings, it is beneficial to large-scale application.
