Abstract
The present invention relates to a seedling cultivating method for raising rate of emergence of paris polyphylla smith var, yunnanensis seeds. Said method is short in time of emergence, high in rate of emergence and low in cost for cultivating seedlings. Said method includes the following steps: selecting ripe seed, removing outer seed peel, placing the seed and soil in a seedling cultivating frame interior by layers according to the volume ratio of 1:3-5, under the condition of that the relative humidity of soil in the seedling cultivating frame is 50-80% and its temperature is 18-20deg.C placing for 90-130 days, then sowing in greenhouse seedling bed, the thickness of greenhouse seedling bed soil layer is 5-10cm and the thickness of covering soil after sowing is 1-3cm. As compared with other method for cultivating seedlings the time for cultivating seedlings can be shortened to 5-6 months, and the rate of emergence can be reached to above 60%.
Description
Technical field
The present invention relates to a kind of Yunnan Rhizoma Paridis seed seedling-raising method.
Background technology
The Yunnan Rhizoma Paridis main method of growing seedlings mainly contains seed seedling-raising and rhizome segment two methods of growing seedlings, and nursery stage is short though the rhizome segment is grown seedlings, and the seedling cost is higher; Seed seedling-raising need under field conditions (factors) could sprout through two years, and emergence rate is quite low because the Yunnan Rhizoma Paridis seed has the physiological property of embryo after-ripening.In order to solve the low problem of Yunnan Rhizoma Paridis seed bud ratio, Chinese Academy of Sciences's Kunming plant research has been carried out the research of Yunnan Rhizoma Paridis seed germinating method, and applied for " Yunnan Rhizoma Paridis seed sprouting and propagation method thereof " Chinese patent (patent No. is ZL98118955.5), this patent has proposed the Yunnan Rhizoma Paridis seed and has handled by indoor a series of chemical reagent and change temperature-accelerated germination, the training of employing group again propagation, last every seed seedling and can breed the method for 3-4 bud, but the one, seed sprouting program complexity, cost height, the 2nd, do not propose to improve the concrete grammar of emergence rate.
Summary of the invention
In order to solve the long and low problem of emergence rate of Yunnan Rhizoma Paridis seed sprouting time, the invention provides the seedling-cultivating method of the Yunnan Rhizoma Paridis seed that a kind of seedling-growing time is short, emergence rate is high and seedling cost is low.
After the present invention is achieved in that the Yunnan Rhizoma Paridis mature seed is removed exosper, with seed and loam by volume 1: the 3-5 layering is placed in the frame of growing seedlings, after placing 90-130 days under the frame relative moisture of the soil 50-80% that grows seedlings, 18～20 ℃ of conditions of temperature, to the greenhouse seeding in nursery bed, after planting thickness of earth covering is 1-3cm.
Embodiment
1. the collection of seed and processing
The primary work of Yunnan Rhizoma Paridis seed seedling-raising is to gather colory seed, generally gathers seed in the 9-10 month.Choose the seed of external form mature and plump when gathering, seed exosper color peony, soft and succulency.Seed will in time be handled behind the seed collection, preventing to pile up the back takes place to go rotten, after gathering institute's seed collecting is placed gauze, in flowing water, rub with the hands and remove exosper, clean seed, remove the transparent tiny seed that feels like jelly, select big or small uniformity and thousand kernel weight seed greater than 30 grams, seed is smooth milky, and pellet hardness is higher.
2. the vernalization of seed
The Yunnan Rhizoma Paridis seed is the embryo after-ripening seed, and seed embryo form rests on the protocorm embryo stage when gathering, and the growth of embryo and sprouting and temperature and humidity are closely related.With seed and loam by volume 1: the 3-5 layering is placed in the frame of growing seedlings, and places 90-130 days under the frame relative moisture of the soil 50-80% that grows seedlings, 18～20 ℃ of conditions of temperature.
3, the sowing of seed
The vernalization of seed finishes the back to the greenhouse seeding in nursery bed, and railway carriage or compartment, seedbed, greenhouse face soil thickness is 5-10cm, and after planting thickness of earth covering is 1-3cm.In order to cultivate strong sprout, soil is grown seedlings by mountain base soil, red soil, the compost of dusting cover mixed in 3: 4: 3 by volume excessively in the seedbed, greenhouse.
The invention provides the seedling-cultivating method of the Yunnan Rhizoma Paridis seed that a kind of seedling-growing time is short, emergence rate is high and seedling cost is low.The one, indoor vernalization is placed in the layering of 50-80% loam with relative moisture, avoided influencing each other in the radicle growth process, the 2nd, take after high temperature treatment just live, avoided the laboratory alternating temperature to handle, reduced production cost, the 3rd, seed base-root contacts with the seedbed early, has improved emergence rate.The present invention is emerged the Yunnan Rhizoma Paridis seed the 2nd year April in spring after seed collecting; compare with other seedling-cultivating method, seedling raise period shortens 5-6 month, and emergence rate can reach more than 60%; emergence rate improves more than 1 times, can realize batch production, the scale of Yunnan Rhizoma Paridis seed seedling-raising.
Claims (2)
1. seedling-cultivating method that improves the Yunnan Rhizoma Paridis seeding ratio, after it is characterized in that the Yunnan Rhizoma Paridis mature seed is removed exosper, with seed and loam by volume 1: the 3-5 layering is placed in the frame of growing seedlings, after placing 90-130 days under the frame relative moisture of the soil 50-80% that grows seedlings, 18～20 ℃ of conditions of temperature, to the greenhouse seeding in nursery bed, railway carriage or compartment, seedbed, greenhouse face soil thickness is 5-10cm, and after planting thickness of earth covering is 1-3cm.
2. a kind of seedling-cultivating method that improves the Yunnan Rhizoma Paridis seeding ratio according to claim 1 is characterized in that seedbed, the greenhouse soil of growing seedlings was mixed by mountain base soil, red soil, the compost of crossing dusting cover in 3: 4: 3 by volume.
