Abstract
The invention discloses a method for increasing the yield and improving the quality of eggplant hybrid seeds, comprising the following steps of: planting female parents at the density of 1600/667m<2>, and collecting large flower buds to bloom next day at night or pollen of initially blooming flowers of a male parent in the morning, carrying out castration at a large bud state in first 1-2 days before the female parent blooms, immediately pollinating after the castration is finished, and repeatedly pollinating next day. The method provided by the invention can be used for reducing the eggplant seed production cost, increasing the seed production efficiency, reducing operation trouble, increasing seed yield and improving seed quality so as to be a feasible method for eggplant seed production.
Description
Technical field:
The present invention relates to eggplant seeding technique field, specifically a kind of method that improves eggplant crossbreed seed production and quality.
Background technology:
According to the FAO statistics, China's eggplant area under cultivation had surpassed 1,000,000 hm in 2008
2, account for 53.7% of the total area under cultivation in the world, being in great demand of annual eggplant seed.At present, the cultivar of adopting in China's eggplant production is the first generation of hybrid basically, high, the not unstable phenomenon of ubiquity output in the hybrid seed production process.
Summary of the invention:
The object of the invention is to improve eggplant crossbreed seed production and quality, reduction breeding cost.
1 eggplant production of hybrid seeds plant planting density adopts usually:
About 2500 strains of planting density/hm
2About, cause eggplant stuffy, easy susceptible decayed fruit has affected the output of crossbreed.
2 eggplant seed production and pollination methods adopt usually:
Bloom at female parent and to carry out the same day then carrying out once only controlled pollination morning next day after the large flower bud phase castrates, this method makes the column cap pollination not exclusively easily, easily causes flower abscission, and fruit-setting rate is low, has had a strong impact on output and the quality of eggplant seed; If carry out pollination more than 3 times, will increase production cost.
For above situation, we are to the castration of the different flower bud of female parent phase, different pollination time and plant adjustment output and the quality influence to hybrid seeding, carried out the Upgrading of cross-breeding method, the clear and definite several principal elements that affect eggplant hybrid seeding seed production and quality are for the production of eggplant hybrid seed provides reference frame.
To achieve these goals, technical scheme of the present invention is: not tight to the appearance requirement of fruit in eggplant seed is produced, 6-8 fruit stayed in the two bars trainings of maternal employing, and planting density is 1600 strains/667m
2, with method 1 ratio, obviously improved output and the quality of seed; Maternal was to castrate the large flower bud phase on bloom the previous day or the same day, male parent gathers large bud or the first pollen pollination of opening of harvesting in early morning that will open in the 2nd day between the lights, repeated pollination on the 2nd day once, this pollinating method is compared with the common method that adopts 2, has improved seed production and seed quality.
Specific embodiments:
1. this raising eggplant seed output and quality method are to realize by pollination technique, planting of maternal density, should take into full account the several principal elements and maternal growth characteristics and the conditions such as maternal and male parent flowering time synchronism that affect eggplant hybrid seeding seed production and quality.
2. according to the parents'growth characteristic, the reasonable arrangement seedling raise period, the planting proportion of Parent is 1: 6 during field planting, maternal plant planting density 1600 strains/667m
2, adopt the method for two bars trainings, still hour select fine day at side shoot as far as possible during training and carry out.For improving hybrid seed yield, extract early the door nightshade, should select and nightshade, four female bucket flowers, octahedral wind flower be hybridized 8～10 flowers of every strain pollination. protect about 6～8 fruit.The large bud of selecting second day or open in the 3rd day is castrated, and it is little to castrate too early bud, operation inconvenience, the column cap of easily damaging, evening then easily produce selfing, affect purity of hybrid.So, castrate to want in good time, and the column cap that prevents from damaging, keep petal complete.When paternal pollen is sufficient, as much as possible pollen is dipped on column cap gently.Press the upwards pollination of the solid flower of side shoot every day, expanded such as fruitlet after several days, illustrate and pollinate successfully that generally pollination will be done severally more, but final every strain is looked the plant strain growth situation and can be stayed 6-8 fruit.
3. management method:
3.1 seeding and seedling raising
District of Shanghai is reserved seed for planting sowing time of eggplant spring generally in early January, and the seed collecting phase is in mid-July.Autumn, eggplant was reserved seed for planting sowing time in mid-July, and the seed collecting phase is in December.。But during the ripe similar temperament of two parents the same period seeding and seedling raising; When if the ripe property of two parents is variant, but late-maturing parent's inseminate early and properly, to facilitate parents' florescence consistent.
3.2 field planting
Will make high furrow in the booth, the furrow height is more than 20 centimetres, to be conducive to root growth.Common 40 * 8 meters booths are made 4 high furrow, every furrow kind two row, field planting during common seedling 3-4 sheet true leaf.Spacing in the rows is about 40 centimetres.Use sufficient fertilizer before the bedding, furrow face covering with plastic film.
3.3 collect seed
In the production of hybrid seeds. we generally gathered in the time of 55～60 days, and after-ripening was cut away the carpopodium part after 2～3 days, were placed on and smashed rear, oven dry clean with clear water in the machine.
The rich water quality management of cultivation 3.4 reserve seed for planting
Before the Parent field planting, must use sufficient fertilizer and the composite fertilizer of becoming thoroughly decomposed, sufficient moisture should be arranged seedling stage, make it send out as soon as possible seedling.Water and to decide on soil regime, can not make soil excessively wet, before Fruit, can suitably water first and second rich water.
4. other management method is consistent with production cultivation conventional method.
Claims (3)
1. a method that improves eggplant seed output and quality is characterized in that: about 1600 strains of planting of maternal density/667m
2Male parent should gather the 2nd day large bud or the first pollen of opening of harvesting in early morning that will open between the lights, maternal before blooming 1～2 day, carry out the large flower bud phase and castrate, pollinate immediately after the castration, repeat pollination on the 2nd day, will significantly improve output and the quality of eggplant hybrid seed.
2. the method for raising eggplant seed output according to claim 1 and quality is characterized in that: about 1600 strains of planting of maternal density/667m
2Employing repeats pollination for 2 times to female parent.
3. the method for raising eggplant seed output according to claim 1 and 2 and quality is characterized in that: used Pollination Modes only uses in the eggplant production of hybrid seeds.
