The invention discloses a kind of rice cultivating method, comprise the following steps：(1) Juvenile stage：Using " eastern wild type " cytoplasm male sterility line as female parent, the curved fringe type kind rice resisted high yield is made into male parent more；(2) selection cross：By maternal and paternal hybrid, obtain combined hybrid kind one from generation to generation, the seed of the generation of combined hybrid kind one is planted respectively, selection fringe portion is with the obvious advantage, the good combination of parent complementary, a generation seed of choosing seeds to obtain；(3) strain nursery is established：The generation seed that step (2) is obtained is planted, during the maturity period, the yielding ability first carried out between cell compares, carry out comparing between individual again in the good cell of yielding ability, choose the good individual plant of variety character, indoor species test is carried out, spike length, spike weight, Spikelet density, setting percentage and exterior quality is investigated, obtains target variety seed.The present invention, which has, cultivates that fringe portion is sane, resistant to lodging and high yield plant type rice that disease resistance ability is all outstanding technique effect.
Description
Technical field
The present invention relates to rice cultivating technical field, more particularly to a kind of rice cultivating method.
Background technology
At present, rice is the most important cereal crops in China, with the growth and growth in the living standard of population, to rice
Demand it is increasing, but limited by water resource and cultivated area, plus economic development and the propulsion of urbanization, rice seed
Plant area to have had a declining tendency, therefore, improving for rice total output can only realize this by the raising of unit yield from now on
The approach of target mainly has two kinds, first, cultivation condition and technology (cultivation management) are improved, second, seed selection yield potentiality is than existing
The higher new rice variety of kind, and can the yield potentiality of kind in itself be the key that obtain high yield, therefore, Super High Yielding Rice
The hot subject that the election effects of (super hybridization rice) new varieties are always international, domestic breeding men are studied.China is in Yield Breeding
Aspect obtains the achievement to attract people's attention, and the utilization of rice heterosis (three line method, two line method) makes the Yield Breeding in China alive
Maintain the leading position in boundary, and grow up on the basis of conventional rice breeding, therefore conventional breeding is foundation stone, having can not
The effect of replacement.And conventional rice breeding is mainly that the breakthrough of yield is obtained by the innovation of plant type of rice, in current high yield
On the basis of plant type, how plant type innovation is carried out, which type of plant type selected, be the difficult point of breeding, and variety yield is broken through
Key point.Although some plant type yield are high, disease-resistant performance and lodging resistance are poor.
The content of the invention
It is an object of the invention to：In order to solve prior art high-yield rice exist disease-resistant performance and lodging resistance compared with
The problem of poor, the present invention provide a kind of rice cultivating method.
The present invention specifically uses following technical scheme to achieve these goals：
A kind of rice cultivating method, it is characterised in that
(1) Juvenile stage：Using " eastern wild type " cytoplasm male sterility line as female parent, the curved fringe type kind rice that will resist high yield more
Make male parent；
(2) selection cross：By maternal and paternal hybrid, combined hybrid kind one is obtained from generation to generation, by the generation of combined hybrid kind one
Seed is planted respectively, the plant height of each plant is recorded, per total grain panicle number, setting percentage, mass of 1000 kernel, according to fringe portion Heterosis and two
The complementarity of parent, selection fringe portion is with the obvious advantage, the good combination of parent complementary, every fringe sowing 35~55 with the obvious advantage
Grain, 5500~6500 seeds, a generation seed of choosing seeds to obtain are received altogether；
(3) strain nursery is established：The generation seed that step (2) is obtained, per 40 plants of cell, the plantation of 5 × 8 rows；It is ripe
During the phase, the yielding ability first carried out between cell compares, and carries out comparing between individual again in the good cell of yielding ability, chooses variety
The good individual plant of shape, indoor species test is carried out, investigate spike length, spike weight, Spikelet density, setting percentage and exterior quality, retain average fringe
Grow at 22 centimetres~25 centimetres, average 5.2 grams~5.8 grams of spike weight, Spikelet density 9.2/centimetre~9.8/centimetre it
Between, individual plant of the setting percentage more than 95%, obtain target variety seed.
Preferably, in above-mentioned steps (3), the comparative approach between cell is as follows：Per cell three individual plants of the second row
Be compared, caught with the right hand from individual plant bottom, moved to fringe portion, while jog, feel between two cells the rugosity of individual plant and
Fringe portion weight, fringe is thick, fringe severe one is preferable cell, otherwise eliminates；In preferable cell, compare in cell per the rugosity of individual plant fringe
And regularity, select in thick and neat, otherwise eliminate.
Preferably, also including program of basking seeds, increase program of basking seeds between above-mentioned steps (2) and step (3), establish strain
It is a generation seed to be made thinner solarization 2~3 days before garden.
Preferably, also including seed soaking program, the generation seed by program of basking seeds is put into bactericidal liquid, when one
When generation neutron absorption water reaches the 30~40% of its seed weight, up to saturated water adsorptive value.
It is defined preferably, white belly and embryo of the saturated water adsorptive value on the grain of rice are high-visible.
Beneficial effects of the present invention are as follows：
1. the rice that traditional rice cultivating method is cultivated, although high yield, some kind lodging tolerances and disease resistance
Ability is all poor, rice cultivating method of the invention, and using the method for selection cross, it is sane to cultivate fringe portion, resistant to lodging and anti-
The all outstanding high yield plant type rice of disease ability, has greatly enriched the breeding method of rice, adds brick for China's paddy rice cross breeding technology
Add watt.
2. traditional breeding process few analog really plants situation, rice cultivating method of the invention, further combined with
Actual conditions are planted, the problem of often considering in actual plantation is added in Breeding Process, program of basking seeds is carried out in seed selection,
A generation seed by program of basking seeds, is more prone to survive, improves its germination percentage and germinating energy.
3. the rice cultivating method of the present invention, seed soaking program is further added after program of basking seeds, makes a generation seed
Absorb water and reach the 30~40% of its seed weight, reach saturation capacity, so as to increase the chance of its rudiment, created for a generation seed
Make good condition.
