Abstract
The invention relates to a female-parent direct seeding and male-parent mechanical transplanting method for hybrid rice seed production, belonging to the technical field of agriculture. Male parents raise rice seedlings in a mechanical transplanting breeding way, a walking type two-line rice transplanter is adopted for transplanting, and female parents are directly seeded after the male parent transplantation is finished for two days. The method has the advantages of labor saving, cost saving and high working efficiency and facilitates large area of hybrid rice seed production operation in a certain area.
Description
Technical field
The present invention relates to agricultural technology field, be specifically related to the live male parent machine transplanting of rice of a kind of maternal breeding of hybrid rice method.
Background technology
Breeding of hybrid rice, since eighties of last century the seventies, has been all to walk traditional Parent water-raised seedling, the way that the Parent artificial hand is planted.Along with rural laborer's minimizing in recent years and most between twenty and fifty labours' transfer, bring limitations affect for the large tracts of land 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, the recruitment cost improves year by year, breeding cost constantly rises, suppressed the expansion in certain zone of production of hybrid seeds area, can say 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 units release the male parent water-raised seedling and manually plant, direct planting female parent; The male parent water-raised seedling is manually planted, the artificial rice transplanting isotype of maternal floppy disk seedling.In order to save work, economize this, improve working efficiency, being convenient to can the operation of large tracts of land breeding of hybrid rice in certain zone.My company in 2012 and Anhui Tontru plant industry Co., Ltd and million river seed multiplication farms and natural village, Chaohu Ba Zhen flower gate promote the use of two excellent 4826 and amount to the male parent transplanting of 1000 mu and the brand-new breeding of hybrid rice pattern of direct planting female parent in Chaohu, 125 kilograms every mu, paid seed, obtain the initial success of saving of labor's abridged edition production of hybrid seeds.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method simple, the live male parent machine transplanting of rice of the maternal breeding of hybrid rice of being convenient to implement method.
Technical problem to be solved by this invention realizes by the following technical solutions:
The live male parent machine transplanting of rice of a kind of maternal breeding of hybrid rice method, male parent are pressed the seedling of transplanting breeding mode, adopt hand-held two row rice transplanters to transplant, and maternal live after the male parent transplanting finishes 2 days, the concrete grammar step is as follows,
1, the seed farm field arranges and the base manure use
the million above fields in farm, river 90%, long is 500m, wide is 50m, field is larger, the field poor flatness, serious field north and south drop reaches 30cm, the machinery rotary tillage can't make field smooth, male parent machine rice transplantation and direct planting female parent are all in the situation that do not have water or shallow water to operate, in order to make it smooth, only having the people is that measure is made some little ridges in a large field, make it in small size, reach the effect of opposed flattened, can reach like this after male parent is transplanted and can grow and tiller as soon as possible, female parent is the neat even seedling of seedling after planting, every mu, seed farm base manure is N, P, 5 kilograms, 25 kilograms of K content 48% three element compound fertilizers and urea, after little wheat harvesting, with fertilizer distributor, evenly spread fertilizer over the fields on arrish, with rotovator, plough,
2, male parent transplanting time and culturable standard
first batch of male parent transplanted June 8, 17 days length of time rice seedlings grow, leaf age average out to 3.06 leaves, height of seedling 5cm left and right, male parent is planted two row, the male parent transplant depth 1cm of delegation, another row transplant depth 2.2cm, by artificial shallow, insert and dark inserting, make the male parent of the sowing same period when heading, reach the effect with two phase male parents, railway carriage or compartment, production of hybrid seeds land for growing field crops is wide is 2.2m, the male parent line-spacing is 30cm, spacing in the rows is that 16cm to 18cm does not wait, 2-5, every cave seed seedling, transplanting machine selects Japanese well to close hand-held two row rice transplanters, rice shoot is coiled into tubular from seedling, place on rice transplanter seedling frame balance 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 finished, start sowing maternal June 10, female parent vernalization mode routinely carry out vernalization, after female parent has been 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 field Wang's mud of doing the little ridge are wiped water, the out-of-flatness field, local high place is more dried, the people station does not fall into pin, low local water depth has 4-6cm, because monoblock field area is larger, can only try to achieve opposed flattened at seeding time, therefore first put at seeding time and do the field water layer, first seed is sowed, after planting according to actual conditions, for high place, part, diligent fill with " horse race water " makes its high place, the 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 the solid carbon dioxide layer, prevent the high-temperature boiling bud, reach the effect of the even seedling of Qi Miao, 840 mu of first batch of areas, sowing in maternal 3.5 days finishes,
4, field management
Farming method adopts conventional artificial Planting Patterns management.
The invention has the beneficial effects as follows: the present invention saves work and economizes this, and working efficiency is high, and being convenient to can the operation of large tracts of land breeding of hybrid rice in certain zone.
