Abstract
The invention provides a method for regulating flowering phase of seed production hybrid rice. Paclobutrazol seed dressing for a male parent at later stage delays emergence, and Bihu seed dressing for a male parent at early stage brings emergence forward, so that female parents subjected to earing at early, medium and later stages can accept the pollen of the male parents at different growth stages. The method has the advantages of solving flowering asynchronism, increasing the yield of the seed production rice, improving the quality of the seed production rice, improving the anti-disaster ability of the seed production rice and the like.
Description
Technical field
The invention belongs to pesticides application field, especially in regard to a kind of method at regulation production of hybrid seeds hybrid paddy rice florescence.
Background technology
Due to the factor such as sowing time and weather, fertilising, the yield for often resulting in production of hybrid seeds field is unstable, the flower of male parent and female parent
Phase does not meet, so as to affect the pollination rate of the production of hybrid seeds and the interior quality of production of hybrid seeds hybrid paddy rice.
The content of the invention
It is an object of the invention to provide it is a kind of can solve the problem that male parent female parent flowering asynchronism problem, increase production of hybrid seeds rice yield and
The method at the regulation production of hybrid seeds hybrid paddy rice florescence of quality.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：A kind of method for adjusting the production of hybrid seeds hybrid paddy rice florescence, its
It includes having the following steps：
First, increase male parent with the cultivated area ratio of female parent to 1 to 1, and be staggered；
2nd, date of seeding is adjusted, every a collection of male parent of 4-5 days kinds；
3rd, the male parent paclobutrazol seed dressing postponement of middle and advanced stage is emerged, and the male parent of early stage is emerged ahead of time with green shield seed dressing；
4th, maternal growth potential and resistance is improved using high 28 brassin, makes maternal robust growth improve yielding ability.
Compared with prior art, the present invention has the advantages that：
1. the problem that the Parent florescence do not meet can be made to obtain basic solution.
2. the yield of production of hybrid seeds rice can be increased substantially.
3. ensure that in the breeding after the production of hybrid seeds kind has one significantly to improve in quality of life.
4. the strong synthesis anti-disaster ability of production of hybrid seeds rice can be increased, and seedling body quality is greatly improved.
Specific embodiment
For the technique effect for the technology used in the present invention means being expanded on further He reach, do with reference to embodiments in detail
Describe in detail bright.
The invention provides a kind of method for adjusting the production of hybrid seeds hybrid paddy rice florescence, it includes having the following steps：
First, increase male parent with the cultivated area ratio of female parent to 1 to 1, and be staggered；
2nd, date of seeding is adjusted, every a collection of male parent of 4-5 days kinds；
3rd, the male parent paclobutrazol seed dressing postponement of middle and advanced stage is emerged, and the male parent of early stage is emerged ahead of time with green shield seed dressing；
4th, maternal growth potential and resistance is improved using high 28 brassin, makes maternal robust growth improve yielding ability.
Male parent sows by stages and in groups offer pollen in the present invention, and the female parent of early stage heading does sth. in advance emerging for male parent with green shield,
The male parent that the female parent of later stage heading paclobutrazol is processed provides pollen, makes the female parent of phase morning, noon and afternoon heading and can receive different lifes
Educate the pollen of stage male parent.
Described above has fully disclosed the specific embodiment of the present invention.It is pointed out that being familiar with the field
Scope of any change that technical staff is done to the specific embodiment of the present invention all without departing from claims of the present invention.
Correspondingly, the scope of claim of the invention is also not limited only to previous embodiment.
Claims (1)
1. it is a kind of adjust the production of hybrid seeds hybrid paddy rice florescence method, it is characterised in that：It includes having the following steps：
First, increase male parent with the cultivated area ratio of female parent to 1 to 1, and be staggered；
2nd, date of seeding is adjusted, every a collection of male parent of 4-5 days kinds；
3rd, the male parent paclobutrazol seed dressing postponement of middle and advanced stage is emerged, and the male parent of early stage is emerged ahead of time with green shield seed dressing；
4th, maternal growth potential and resistance is improved using high 28 brassin, makes maternal robust growth improve yielding ability.
