Abstract
The invention mainly aims at providing a cabbage type rape parent seed multiplication method which can not only ensure purity but also realize higher multiplication yield and lower cost. The method comprises the following steps of: sowing rape parent seeds in March, and controlling the growth temperature at 15-25 DEG C; transplanting in April, selecting the region with the altitude of above 1000m in Yangtze River valley in the south of Qinling-Huaihe Line in China as a transplanting region, adopting a plastic film for coverage, and breaking the film for transplanting; and enabling progenitive rape parents to bloom in May-June and mature in July-August. According to the invention, the high-altitude low-temperature region of the Yangtze River valley is substantively selected, the sowing is performed in spring, and a means for promoting growth is simultaneously adopted, so that the growth and development of plants can be ensured, and simultaneously, the flowering phase of the plants can be significantly staggered with the flowering phases of similar plants, thus the mixing can be avoided. The parent seed multiplication has good economy and high yield, and the method provided by the invention has extensive popularization and application values.
Description
Technical field
The invention belongs to technical field of agricultural cultivation, be specifically related to the expanding propagation method of rape parental seed.
Background technology
It is the main path of parental seed obtaining crossbreed that parental seed expands numerous, the purity concerns of its seed to the seed purity of crossbreed and quality, the safety of relation agricultural production and efficiency.In prior art, in order to obtain the as far as possible high parental seed of purity, it is numerous mainly to adopt the expansion carrying out parental seed in two ways.For cabbage type rape: or be exactly adopt booth isolation breeding, or the large-scale isolated area of more than 1500 meters is set at breeding field periphery exactly, other any crucifers can not be had within the scope of isolated area.To prevent pollen and parent's Hybridization and degeneration of other crucifer, cause the reduction of parental purity.
Adopt booth breeding rape parental purity good, but cost is high, only the construction cost of booth just reaches the every square meter of 500-1000 unit.And due to the effect of the propagation pollen that lacks air-flow and wind-force in booth, so the solid effect of rape is undesirable in booth, the particularly solid weak effect of male sterile line, the output of breeding is extremely low.
Adopt isolated area breeding rape parent output large, but the workload that isolated area is arranged is also large, need cleaning and remove other crucifer, and the co-ordination of periphery is complicated, cost is high, and purity does not also ensure, once isolated area impurity elimination not thoroughly or run into the other factorses such as strong wind and just easily cause parent's Hybridization and degeneration.
So expansion numerous rape parental seed in economical and efficient ground always is an insoluble technical barrier in prior art.
Summary of the invention
Main purpose of the present invention is to provide one can ensure purity, has again higher reproductive output, and lower-cost rape parent propagation producing method for seed.
For achieving the above object, the technical solution adopted in the present invention is: a kind of Parents in Brassica napus L seed expanding propagation method, and step comprises:
Nursery: sow rape parental seed March, controls growth temperature at 15-25 DEG C;
Transplant and cultivate: April transplants, height above sea level more than the 1000 meters area on the south Huaihe River, China Qinling Mountains is selected in region of planting, and adopts plastic mulching rupture of membranes to transplant; The rape parent of breeding was bloomed in 5-6 month, and 7-8 month is ripe.
The present invention selects to sow the seed in spring, and the area plantation more than height above sea level 1 km of south China, by controlling the environmental temperature of growth of seedling, transplant and adopt plastic mulching rupture of membranes to transplant the soil temperature of guarantee plant strain growth higher than ambient soil temperature, so just can ensure that the condition of growing of rape is suitable for, ensure that rape growth is perfect; Growing environment nature simultaneously, ensures that the output of breeding is high, male sterile line about 50 kgs/acre, restorer about 100 kgs/acre.Simultaneously because the sowing time in spring, and the rape seed time of south China is nearly all in autumn last year, so just significantly staggers season with large-scale rape seed.So the rape parent of the present invention's breeding is naturally when 5-6 month blooms, the crucifers such as the rape of south China 3, April blooms, 4, May harvest home.Ensure that other crucifers around breeding field thank to flower already, so just completely avoid the Hybridization and degeneration that other crucifer pollen cause rape parent pollination, thus ensure the purity of rape parent propagation.And the technology that such breeding adopts and condition all simple and easy to get, reproductive-cost comparatively booth or isolation strip is set significantly reduces.Core of the present invention and technology focus on sowing time selection, region is selected and mulch film rupture of membranes transplanting method, and other such as condition such as water, fertilizer does not have particular/special requirement, with reference to prior art, or can do any technological improvement.
Preferred scheme is further:
Transplanting to cultivate selects the area of the height above sea level more than 1000 meters of the Yangtze river basin to carry out.Being more preferably to transplant to cultivate selects the SUBMOUNTAINOUS AREA of the height above sea level 1000-1500 rice of the Yangtze river basin to carry out.This area addresses scope is wide on the one hand, contains Sichuan, Chongqing, Hubei, Hunan, Anhui, Deng Duo provinces and regions, Jiangxi; These areas and height above sea level position are because climate temperature is comparatively even simultaneously, are convenient to the present invention and adopt uniform technical feature to make technological knowledge popular.And there is the experience of long-term planting rape in these areas, are convenient to Technique Popularizing.
In order to ensure that the growth temperature of seedling can adopt numerous embodiments during method nursery of the present invention, because seedling small volume, so raise seedling in greenhouse can be adopted, also cost can not be increased; Or adopt the nursery of seedling dish arch film, more convenient operation, cost is lower, and adaptability is stronger simultaneously.Temperature in described arch film controls at 15-25 DEG C.Be beneficial to most the growth of seedling like this, concrete operations are also very convenient, as long as open the heat radiation of arch film when temperature is too high, night generally covers arch film and can ensure this temperature condition.
Further, described growth of seedling is transplanted for one month at once.Because the conditions such as the temperature of transplanting environment of the present invention April all better, and through a growth in month, plant was also comparatively large, grows more advantageous rapidity after transplanting, also to avoid in seedling dish the nutrients such as rich water not enough.
From technical characteristic of the present invention and technical scheme, the present invention is in fact the low temp area of the High aititude selecting south China, adopt sowing in spring, adopt the means of growth promoting effects simultaneously, growing of plant can be ensured, significantly stagger again simultaneously and expand numerous plant and the florescence of similar plant, avoid mixing.The parental seed that such method is obviously also suitable for the similar plants such as the rape similar with cabbage type rape expands numerous.
