Description
Technical field
The present invention relates to agricultural technology field, be specifically related to a kind of maternal breeding of hybrid rice live male parent machine transplanting of rice method.
Background technology
Breeding of hybrid rice, since eighties of last century the seventies, has been all walk traditional Parent water-raised seedling, the way that Parent artificial hand is planted.Along with rural laborer reduced and the between twenty and fifty labor transfer of majority in recent years, brought limitations affect to the large area production of hybrid seeds.The production of hybrid seeds in recent years turns to rich and influential family's production of hybrid seeds pattern by early stage peasant household's production of hybrid seeds, recruitment is more and more in short supply, recruitment cost improves year by year, breeding cost constantly rises, inhibit the expansion in certain region of production of hybrid seeds area, can saying that the development of breeding of hybrid rice runs into the bottleneck of labour's restriction, in order to find breach, a lot of production of hybrid seeds unit releases male parent water-raised seedling and manually plants, direct planting female parent; Male parent water-raised seedling is manually planted, the artificial rice transplanting isotype of maternal floppy disk seedling.Economizing this to save work, improving working efficiency, being convenient to can the operation of large area breeding of hybrid rice in certain region.My companies in 2012 and Zhong Ye Co., Ltd of Anhui Tontru promote the use of two excellent 4826 at Chaohu million river seed multiplication farm and Chaohu Ba Zhen flower natural village, gate and amount to the male parent transplanting of 1000 mu and the brand-new breeding of hybrid rice pattern of direct planting female parent, 125 kilograms, paid every mu, seed, obtains the initial success of the dart transfer production of hybrid seeds.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of method, is convenient to the maternal breeding of hybrid rice live male parent machine transplanting of rice method implemented.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of maternal breeding of hybrid rice live male parent machine transplanting of rice method, male parent presses the seedling of transplanting breeding mode, adopts hand-held two row rice transplanter to transplant, and maternal live after 2 days in male parent transplanting end, concrete grammar step is as follows,
1, seed farm field arranges and base manure use
Million farm, river more than 90% fields, long is 500m, wide is 50m, field is larger, field poor flatness, serious field north and south drop reaches 30cm, machinery rotary tillage cannot make field smooth, male parent machine rice transplantation and direct planting female parent are all operate when not having water or shallow water, in order to make it smooth, people is only had to be that measure makes some little ridges in one piece of large field, make it in small size, reach the effect of opposed flattened, can grow as soon as possible after can reaching male parent transplanting like this and tiller, female parent is the neat even seedling of seedling after planting, every mu, seed farm base manure is N, P, K content 48% three element compound fertilizer 25 kilograms and 5 kilograms, urea, evenly spread fertilizer over the fields on arrish with fertilizer distributor after little wheat harvesting, plough with rotovator,
2, male parent transplanting time and culturable standard
First batch of male parent transplants June 8, 17 days length of time rice seedlings grow, leaf age average out to 3.06 leaf, height of seedling about 5cm, male parent plants two row, a line male parent transplant depth 1cm, another row transplant depth 2.2cm, inserted with dark by artificial shallow inserting, the male parent that the same period is sowed reaches the effect with two phase male parents when earing, railway carriage or compartment, production of hybrid seeds land for growing field crops is wide is 2.2m, male parent line-spacing is 30cm, spacing in the rows be 16cm to 18cm not etc., 2-5, every cave seed seedling, transplanting machine selects Japanese well to close hand-held two row rice transplanter, rice shoot coils into tubular from seedling, place rice transplanter seedling frame balances smooth out with the fingers suitable, can transplant, first batch of male parent transplanting time is 4 days,
3, direct planting female parent
After male parent is transplanted and is terminated, maternal June 10 starts sowing, female parent vernalization mode routinely carry out vernalization, after female parent has urged bud, directly cast in railway carriage or compartment reserved between male parent, the maternal mu amount of broadcasting is 1.65 kilograms, sowing time-division furrow are quantitative, during sowing, the basic condition in land for growing field crops is, more smooth field or do the little ridge field Wang mud wipe water, out-of-flatness field, locally high place is more dry, people station does not fall into pin, low local water depth has 4-6cm, because monoblock field area is larger, opposed flattened can only be tried to achieve at seeding time, therefore dry field water layer is first put at seeding time, first seed is sowed, after planting according to actual conditions, for the place that local is high, the diligent place of filling with " horse race water " and making it high, male parent rice shoot can be tillered by normal survival and growth, female parent can normally be emerged, low-lying place is manually managed ditch and is put solid carbon dioxide layer, prevent high-temperature boiling bud, reach the effect of the even seedling of Qi Miao, first batch of area 840 mu, sowing in maternal 3.5 days terminates,
4, field management
Farming method adopts the management of conventional manual's Planting Patterns.
The invention has the beneficial effects as follows: the present invention saves work and economizes this, and working efficiency is high, being convenient to can the operation of large area breeding of hybrid rice in certain region.
