Abstract

The present invention discloses a multi-generation rejuvenation culture method of oriental lily seed bulbs, which solves the problem that the oriental lily seed bulbs can be produced only in one-crop cut flowers. The method comprises the following steps: leaving 15 to 25cm of stalk and 10 to 12 leaves during each round of flower cutting, sterilizing a substrate after flower cutting, watering and applying fertilizer, and culturing the seed bulbs for one month to rejuvenate the seed bulbs; picking the first and the third round of flowers in winter; refrigerating rejuvenated seed bulbs through natural low temperature, gradually cooling down a green house to-4 DEG C, freezing the culture substrate in 3 to 4cm deep, and keeping the temperature at-1.5 (+/-) 0.5 DEG C and humidity at 60% to 70% around the seed bulbs; gradually raising the temperature up to defreeze the substrate after a month and entering normal management; digging out, grading, sterilizing and packaging the rejuvenated seed bulbs harvested after the second round of flowers, treating the rejuvenated seed bulbs in a cold treatment storehouse under the temperature condition of-1.5 (+/-) 0.5 DEG C for 10 to 12 weeks, then loading out of the storehouse and planting. The present invention can guarantee that cut flowers of all rounds have quality almost the same as that of the first round of flowers.

Description

Multi-generation rejuvenation cultivating method of oriental lily ball

Technical field:

The present invention relates to a kind of multi-generation rejuvenation cultivating method of oriental lily ball.

Background technology:

It is shorter that China carries out the time of oriental hybrid lily fresh cut-flowers commodity production, only has about ten years.Lilium oriental relies on from foreign procurement, needs about 100,000,000 of imports at present every year approximately.Lilium oriental fresh cut-flowers production technology remains so far according to external method, is used for producing one batch of cut-flower and just passes into disuse.Cause production cost higher, make kind of a ball supply be limited by international vendor fully again.Domestic oriental hybrid lily fresh cut-flowers some enterprise of main producing region and scientific and technological unit are also in many batches of operation techniques of experimental study lilium oriental.But do not see as yet so far about using lilium oriental to carry out the reported in literature and the patent announcement of four batches of cut-flowers.

Summary of the invention

The purpose of this invention is to provide a kind of multi-generation rejuvenation cultivating method of oriental lily ball, can only carry out the problem that one batch of cut-flower is produced to solve existing lily ball.

The step of cultivation method of the present invention is, the lilium oriental of first batch of flower was seeded in the greenhouse mid-July to mid-September, (matrix formulations peat: river sand: cow dung: falx straw is 6: 1.5: 1.5: 1) to adopt soilless substyate culture, carry out temp. and humidity, liquid manure is managed between the gas field, mid or late January late October to next year the fresh cut-flowers of gathering; When first batch of flower shears flower, stay 15-25cm cane and 10 to 12 blades; Use carbendazim mixed methyl isofenphos to the matrix disinfection after picking flowers, and the fertilising of watering; Carry out a month foster ball, make kind of a ball rejuvenation; On the spot kind of ball is carried out cold treatment then, the greenhouse progressively lowers the temperature, and through 7-10 days, makes greenhouse temperature drop to-4 ℃, and the cultivation matrix dark 3-4cm that freezes plants around the ball substrate temperature-1.5 ℃ ± 0.5 ℃, humidity 60%-70%, time 1-2 month;

The kind ball warp of second batch of flower is crossed above-mentioned processing, begin preheating in the first tenday period of a month to late Febuary January next year,, make in the greenhouse temperature reach 20～25 ℃, night daytime and reach 15～18 ℃ by 7-10 days heat temperature raisings progressively, matrix is all thawed, and substrate temperature is stabilized in 15 ℃ around the kind ball; Enter the normal management that cut-flower is produced, the first tenday period of a month in May to early July the cut-flower of gathering, gather and carry out one month foster ball rejuvenation after finishing, dig out kind of a ball in mid or late June to late August then; To kind of a ball select, classification, sterilization, packing, send into the cold treatment storehouse again; In the storehouse, keep-1.5 ℃ ± 0.5 ℃ temperature condition to handle 4-6 week,, can prolong the cold preservation time under-1.5 ℃ of temperature in the storehouse, be 6-8 week then according to the arrangement in sowing time;

Kind ball mid-September to the mid or late November outbound of the 3rd batch of flower sowing, field planting method is identical with thereafter cultivation management and first batch, and different is will add 1/3rd not have used matrix, in mid or late December to the next year mid or late March fresh cut-flowers of gathering; Kind ball rejuvenation after cut-flower is gathered and the cold treatment method kind ball processing method after first batch of flower picked flowers is identical;

The cultivation management method of the 4th batch of flower is identical with second batch, emerges in mid-March to early April, and June to mid or late August gathers.

The quality that the present invention can guarantee each batch cut-flower is the same with first batch of cut-flower substantially.Owing to need not buy new kind ball, second batch, the 4th batch does not need again to sow again, only need to strengthen to the matrix sterilization with suitably add the new matrix of a part and some fertilizer, so second batch and after each batch production this less than half of first batch of production cost.

Embodiment
