Abstract
The invention discloses paddy rice castration hybrid seed production method, comprise the following steps：(1) seed breeding base selection, selection light and heat condition is good, soil fertility is fertile, physical features is flat, the field without soil-borne disease as the production of hybrid seeds day, plantation other crops of not arranged flowers in seed farm, with the plantation distance of the paddy rice of other kinds more than 50 meters；(2) Parent field arrangement, male parent and female parent press 1:3‑1:5 configurations, in maternal area of male parent kind；(3) florescence of maternal and male parent is adjusted, interval sowing, nitrogen fertilizer application make the flower synchronization of the two；(4) emasculation, after female parent becomes civilized, male flower is extractd with tweezers before male flower anther cracking when every morning 9 10, then firmly to move 78 maternal branches flies away flower pesticide, when maternal female flower is opened terminates to enter the opening of second batch male flower, male flower and alabastrum is plucked totally；(5) pollinate, carried out during that afternoon 35, pollinated using " single flower pollination method ", " binding pollination method " or " bottle pollination method ".
Description
Technical field
The present invention relates to paddy rice producing method for seed, more particularly to paddy rice castration hybrid seed production method.
Background technology
Paddy rice cross breeding is that rice breeding work Zhang Gailiang rice varieties proterties and creation source of variation are indispensable important
Approach.Existing paddy rice cross breeding method respectively has advantage and disadvantage：1st, clever emasculating method is manually cut relatively to take a lot of work, to grain husk flower damage compared with
Greatly, and unless you give your whole attention to it, floral organ will be damaged, setting percentage is reduced；2nd, lukewarm water gametocide method can Selfing avoidance, setting percentage is higher, but will
Ask the preference temperature needed for grasping different rice varieties gametocides and time.Also to accomplish not only all to kill but also not to post stamen
Head causes to damage, and its method workload is big and comparatively laborious；3rd, vacuum gametocide method is that the side of paddy rice stamen is pumped out using vacuum
Method, its speed is fast, and flower pesticide is sucked without damaging column cap, but needs corollary equipment, is limited larger by condition element；4th, chemistry goes
Male method, emasculation is not thorough, and medicament residual is high, and environmental pollution is heavier.
The content of the invention
The invention aims to provide a kind of paddy rice castration hybrid seed production method.
According to an aspect of the invention, there is provided paddy rice castration hybrid seed production method, comprises the following steps：(1) production of hybrid seeds
Base selection, selection light and heat condition is good, soil fertility is fertile, physical features is flat, the field without soil-borne disease as the production of hybrid seeds day, in seed farm
Do not arrange flowers plantation other crops, with the plantation distance of the paddy rice of other kinds more than 50 meters；(2) Parent field arrangement, father
This and female parent press 1:3-1:5 configurations, in maternal area of male parent kind；(3) florescence of maternal and male parent is adjusted, interval sowing,
Nitrogen fertilizer application makes the flower synchronization of the two；(4) emasculation, after female parent becomes civilized, when every morning 9-10 before male flower anther cracking
Male flower is extractd with tweezers, then firmly to move 7-8 maternal branch flies away flower pesticide, when the opening end of maternal female flower enters the
When two batches of male flowers are opened, male flower and alabastrum is plucked totally；(5) pollinate, carried out during that afternoon 3-5, using " single flower pollination method ",
" binding pollination method " or " bottle pollination method " is pollinated.
In some embodiments, the 2000-2800 plants/100m of planting of maternal density of the step (3)2, size row kind
Plant, big row 60-65cm, small row 35-45cm；Planting density 3000-3500 plants/100m of male parent2。
Specific embodiment
Further description explanation is made to the present invention below.
The paddy rice castration hybrid seed production method of present invention description, comprises the following steps：(1) seed breeding base selection, selects light
Heat condition is good, soil fertility is fertile, physical features is flat, the field without soil-borne disease as the production of hybrid seeds day, do not arranged flowers in seed farm plantation other
Crop, with the plantation distance of the paddy rice of other kinds more than 50 meters；(2) Parent field arrangement, male parent and female parent press 1:3-
1:5 configurations, in maternal area of male parent kind；(3) florescence of maternal and male parent is adjusted, interval sowing, nitrogen fertilizer application make the two
Flower synchronization；(4) emasculation, after female parent becomes civilized, plucks male flower with tweezers before male flower anther cracking when every morning 9-10
Remove, then firmly to move 7-8 maternal branch flies away flower pesticide, terminate to enter the opening of second batch male flower when maternal female flower is opened
When, male flower and alabastrum is plucked totally；(5) pollinate, carried out during that afternoon 3-5, using " single flower pollination method ", " binding pollination method "
Or " bottle pollination method " is pollinated.
Wherein, the 2000-2800 plants/100m of planting of maternal density of step (3)2, the plantation of size row, big row 60-65cm is small
Row 35-45cm；Planting density 3000-3500 plants/100m of male parent2。
