Abstract

The invention discloses a germination accelerating and seedling raising method for melastoma dodecandrum seeds, and belongs to the technical field of plant seedling raising. The method comprises the following steps of: (1) melastoma dodecandrum fruit treatment; (2) melastoma dodecandrum seed pretreatment; (3) seed germination accelerating treatment; and (4) seed sowing and seedling raising and the like. By the method, the germination rate of the melastoma dodecandrum seeds is remarkably improved from conventional 10 to 15 percent to over 50 percent; by germination accelerating treatment, the emergence rate is improved by over 3 times compared with the conventional dry seeds; by the method, the sowing amount is reduced, the dormancy stage is obviously shortened, the emergence rate of a field garden is improved, the time from sowing to a three-leaf stage is shortened from conventional 8 months to about 4 months, and the seedling raising cost is reduced by over one half; and the method is simple, feasible and low in cost, and can be popularized and applied in seedling raising and greening regions.

Description

Harvest the vernalization and the seedling-cultivating method of seed a kind ofly
Technical field
The present invention relates to the botanical seedling culturing technical field, harvest the vernalization and the seedling-cultivating method of seed particularly a kind ofly.
Background technology
Along with the demand to plant variety such as city trees and shrubs and slope protection greening, wild ground cover plant of one's native land more and more receives publicity, much grow extensive, pattern is bright-colored, the florescence is long, kind that have ornamental value is all being attempted and developed.But, mainly still rest on for a long time in the spontaneous situation of excavating, transplanting and supplying with at a low price the development and use of wild ground cover plant resource of one's native land.If things go on like this, both be unfavorable for the protection of wild plant germ plasm resource, also be unfavorable for the wild ground cover plant of one's native land of Application and Development fast and efficiently.
Harvest (Malastoma dodecandrum), claim PUDIJIN, open country fall eggplant, Fructus Fici tikouae again, being the shape shrub that crawls that the Melastomataceae tomonea belongs to, is to have wide, ornamental, the adaptable good native soil that distributes in the regional numerous Resources of Wild in south, Zhejiang to see one of representative of flower ground cover plant.But the seed harvested more small, generally only long 0.4mm~0.8mm, simultaneously, therefore harvesting the Seed Dormancy phase under field conditions (factors) reaches about half a year,, it is higher to the germinating growth environmental requirement, adopt conventional method to grow seedlings and then exist consumption kind of amount big, spended time is long, and percentage of seedgermination is low, be 10-15% only generally, so the development and use of harvesting with being unfavorable for.Therefore, carry out the research that improves percentage of seedgermination and seedling-cultivating method, most important to harvesting the artificial cultivation breeding post.
Summary of the invention
The present invention seeks to, harvest seed at ground and exist seed small, resting stage is long, defectives such as consumption kind of amount is big, and the germination survival rate is low, and spended time is long, a kind of germination rate and germination index height are provided, and growing-seedling period is short, the method that the ground that seedling quality is good is harvested presprouting of seeds and grown seedlings.
The object of the invention is achieved through the following technical solutions.
Harvest the vernalization and the seedling-cultivating method of seed, this method follows these steps to carry out a kind ofly:
(1) harvesting fruit handles: select growth ground even, full, no damage by disease and insect to harvest fruit, through Exposure to Sunlight or≤50 ℃ incubator oven dry, make water content be lower than 5% back sealing, 2-5 ℃ of preservation down, standby;
(2) harvest the seed pre-treatment: with fruit in clear water, soak 16-24 hour to expand soft after, pack into 40 order nylon yarn bags, tying are put in the flowing water and are rubbed with hand, remove pericarp, pulp, clean seed after, take out, drain;
(3) presprouting of seeds is handled: with seed and moistening fine sand by volume 1: after the 2-3 ratio is mixed, put in the 4-5 ℃ of refrigerator individual month of preservation 3-4 and show money or valuables one carries unintentionally to 60% kind of bud; Or seed put be stirred to cooling in the 60-80 ℃ of warm water, soak after 24 hours and pull out, with seed and moistening fine sand by volume 1: after the 2-3 ratio is mixed, be incubated 25 ℃, vernalization 30-40 days to 60% kind of bud and show money or valuables one carries unintentionally; Or seed is dried, puts into the 0.01mg/L brassinosteroid aqueous solution or the 100umol/L methyl jasmonate aqueous solution soak and pull out after 24 hours, with seed and moistening fine sand by volume 1: after the 2-3 ratio is mixed, be incubated 25 ℃, vernalization 30-40 days to 60% kind of bud and show money or valuables one carries unintentionally;
(4) planting seed is grown seedlings: with above-mentioned vernalization seeds treated, be sowed at peat earlier: vermiculite is in 3: 1 the matrix cave dish, moves in the husky bed routinely rich water quality management again to Cheng Miao.
Described moistening fine sand water content is 60%, need in time keep the skin wet to keep this water content during the vernalization.
Beneficial effect of the present invention is:
One, harvests to the present invention the vernalization and the seedling-cultivating method of seed, significantly improved ground and harvested seed germination rate, bring up to more than 50% by the 10-15% of routine;
Two, the inventive method is by after handling the vernalization of seed, and emergence rate can improve more than 3 times than conventional dried Tibetan seed;
Three, harvest seed and after vernalization is handled, both significantly improved germination rate, reduce seeding quantity, obviously shortened resting stage again, improved the ground threshing emergence rate greatly, from sow to tri-leaf period by the shortening to more than 8 months about 4 months of routine, seedling cost can reduce over half; The inventive method is simple, and is with low cost, be easy to apply.
