Description
Technical field
The present invention relates to the breeding method of a kind of vegetable, parent's breeding method of especially a kind of Caulis et Folium Brassicae capitatae, belong to field of plant growing technology.
Background technology
Common head cabbage belongs to Cruciferae, and Brassica genus, for biennial herb plant.Originating in Mediterranean Bei Yan, be now worldwide culturing vegetable, continent country of Europe, the United States is vegetables.Common head cabbage is after 16th century incoming China, due to its adaptability and strong stress resistance, stable yields, storage tolerance again, therefore at China's cultivation development quickly, every Annual planting area has reached more than 400,000 sq-kms at present, all occupies critical role in vegetable supply and the export trade.
Jiangsu Province Caulis et Folium Brassicae capitatae parent propagation is sowed in August substantially, JIUYUE field planting, treats Caulis et Folium Brassicae capitatae spheroid cutter is drawn in next year 2, March a cross openning, helps its bolting.But have a class to be commonly called as the special consolidation of balling of iron ball Caulis et Folium Brassicae capitatae, even if drawing a cross openning at its spheroid, neither often strain can success bolting, frequent main a kind of sedge cannot be extracted out or extract out too late inside ball, and branch is seldom, affects parent's breeding yield.
Summary of the invention
It is an object of the invention to provide a kind of method that the iron ball smooth bolting of Caulis et Folium Brassicae capitatae parent can be made to bloom, improve its parent propagation yield.
The present invention is achieved by the following technical programs:
The parent breeding method of a kind of iron ball Caulis et Folium Brassicae capitatae, comprises the following steps:
1) sowing: adopt hole tray sowing by the end of August；
2) heel in: early September is heeled in once；
3) prepare before field planting: dig Seedling and within first 1 day, field will be heeled in and water permeable；Organic fertilizer 1900～2100kg/667m in land for growing field crops in booth before field planting2, compound fertilizer 28～32kg/667m2；
4) field planting: by the end of September Seedling is dug out field planting booth, normal rich water quality management after field planting；
5) cutting leaf first to process: mid-November, Caulis et Folium Brassicae capitatae center lobus cardiacus starts involute balling, and now siphonal lobe has reached 18, is opened along slicing off the blade 5-6 that outermost grows the earliest bottom petiole by Caulis et Folium Brassicae capitatae siphonal lobe with pocket knife；
6) periodically cut leaf to process: siphonal lobe slices off rear iron ball Caulis et Folium Brassicae capitatae to start the lobus cardiacus of involute balling and can stop curls inward, stop balling to outgrowth；Late November, when siphonal lobe again reach 18, lobus cardiacus start again involute balling time, then slice off 5-6 with pocket knife and open siphonal lobe, lobus cardiacus stops involute starting abduction again；Hereafter wait lobus cardiacus when starting curls inward, then slice off 5-6 with pocket knife and open siphonal lobe, so repeat, until April next year；
7) iron ball Caulis et Folium Brassicae capitatae bolting: start bolting April next year and bloom, spray once with carbendazim when just having started bolting, and keep booth air to circulate, it is prevented that plant is rotted.
The purpose of the present invention can also be realized further by techniques below measure.
The parent breeding method of aforesaid iron ball Caulis et Folium Brassicae capitatae, wherein step 2) in the space between plants heeled in be 8～12cm × 8～12cm.
The parent breeding method of aforesaid iron ball Caulis et Folium Brassicae capitatae, wherein the space between plants of step 4) field planting is 38～42cm × 48～52cm.
The present invention is simple, and relative to existing parent breeding method, the plant bolting rate of the present invention improves 10% than prior art, and blooms early；Plant one-level branch quantity is 3 times of prior art.
Advantages of the present invention and feature, will be made an explanation by the non-limitative illustration of preferred embodiment below, and these embodiments are only used as example and provide.
Detailed description of the invention
Below in conjunction with the iron ball head cabbage varieties B9 embodiment in Jurong City of Jiangsu Province, the invention will be further described.
The step of the present embodiment is as follows:
1) sowing: August 25 adopted 72 hole dish seeding and seedling raisings.(normal Caulis et Folium Brassicae capitatae parent can not broadcast excessively slow about 15 days August sowing time, and sowing the too small vernalization of can not be completed of plant when passing the winter late the coming year will not bolting.)
2) heel in: JIUYUE is heeled in once on 10th, strain spacing 10cm × 10cm.
3) prepare before field planting: JIUYUE will be heeled in field on the 29th and water permeable, field planting land for growing field crops organic fertilizer 2000kg//667m in booth before field planting2, compound fertilizer 30kg//667m2。
4) field planting: Seedling is dug out field planting booth with hoe on 30th by JIUYUE, determines space between plants 40cm × 50cm, normal rich water quality management after field planting.Divide community A and for check plot B Liang Ge community field planting.
5) cutting leaf first to process: November 17, Caulis et Folium Brassicae capitatae center lobus cardiacus starts involute balling, and now siphonal lobe has reached 18, is opened along slicing off the blade 5-6 that outermost grows the earliest bottom petiole by the Caulis et Folium Brassicae capitatae siphonal lobe of community A plant with pocket knife；Check plot B gives free rein to growth.
6) periodically cut leaf to process: community A plant siphonal lobe slices off rear iron ball Caulis et Folium Brassicae capitatae to start the lobus cardiacus of involute balling and can stop curls inward, stop balling to outgrowth；November 30, when siphonal lobe again reach 18, lobus cardiacus start again involute balling time, then slice off 5-6 with pocket knife and open siphonal lobe, lobus cardiacus stops involute starting abduction again；Hereafter wait lobus cardiacus when starting curls inward, then slice off 5-6 with pocket knife and open siphonal lobe, so repeat, until April next year；Check plot B is allowed to growth.
On March 10 next year, check plot B plant draws a cross openning according to prior art at its sphere pocket knife, helps its bolting to bloom, and community A does not process.
Siphonal lobe gathers way relevant with temperature, and temperature Seedling height is fast, and the low growth of temperature is slow；During temperature height, two weeks removes a siphonal lobe, within when temperature is low 1 month, removes a siphonal lobe, and the concrete time starts involute balling with lobus cardiacus and is as the criterion；
7) iron ball Caulis et Folium Brassicae capitatae bolting: start bolting April and bloom, when just having started bolting, community A and check plot B sprays once with carbendazim or all the other sterilization medicines, and keeps booth air to circulate, it is prevented that plant is rotted.
The community A plant bolting rate adopting the present invention reaches 100%, and plant average primary branch amount is 12/strain, and the florescence is April 2 to May 8.The bolting rate adopting the check plot B plant of prior art is 90%, and plant average branch number is 4/strain, and the florescence is April 7 to May 8.
In addition to the implementation, the present invention can also have other embodiments, all employings to be equal to replacement or the technical scheme of equivalent deformation one-tenth, all falls within the protection domain of application claims.
