Abstract
The invention discloses a kind of suitable rice breeding method in fresh water level soilless culture, comprise the following steps：(1) rice varieties of selection Yunnan round-grained rice 40 are maternal, the rice varieties of Shanyou 63 are that male parent is hybridized, and harvest F-1 hybrids paddy rice；(2) the F-1 hybrids seed selfing is obtained into F2 for paddy rice；(3) individual plant that plant forms are good, setting percentage is high is selected, continues selfing, more for seed selection, obtains F6 for paddy rice.It is an advantage of the invention that：The rice varieties that breeding is obtained are through plantation, and setting percentage is up to more than 70%, 350 kilograms of per mu yield paddy rice.Grain of rice high-quality, main physical and chemical index reaches 2 grades of superior rice standards of national standard, and head rice rate is up to 65%.
Description
Technical field
The present invention relates to Rice Cropping technical field, and in particular to a kind of suitable paddy rice in fresh water level soilless culture educates
The method of kind.
Background technology
Rice cropping is carried out typically by the way of paddy field or nonirrigated farmland, with the reduction year by year of cultivated area, exploitation
Carry out rice cultivation using the water surface area large area such as bare place, particularly lake, become a direction of research.
For general rice varieties, it is impossible to effectively absorb the nutrient in waters, cause the hollow kernels of paddy rice；Or
It is the growth for promoting rice root, seedling is more thin and weak.Accordingly, it would be desirable to the characteristics of being directed to fresh water level soilless culture, research is opened
Send a kind of rice varieties of suitable planting.
The content of the invention
It is an object of the invention to provide a kind of high suitable rice breeding method in fresh water level soilless culture of yield.
For achieving the above object, the technical solution adopted in the present invention is：
A kind of suitable rice breeding method in fresh water level soilless culture, comprises the following steps：
(1) rice varieties of selection Yunnan round-grained rice 40 are maternal, the rice varieties of Shanyou 63 are that male parent is hybridized, and are harvested miscellaneous
Plant F1 generation paddy rice；
(2) the F-1 hybrids seed selfing is obtained into F2 for paddy rice；
(3) individual plant that plant forms are good, setting percentage is high is selected, continues selfing, more for seed selection, obtains F6 for paddy rice.
Present lake, is presented eutrophication mostly, and the F6 that breeding is obtained is sowed for paddy rice between March-June, seedling,
The amount for planting 60,000 plants or so according to every mu of waters is planted.It need not be applied fertilizer in planting process, the root length of the kind reaches
60cm or so, paddy rice can directly absorb nutritional ingredient P and N in lake etc..
The present invention has following technical advantage：It is the maternal, rice varieties of Shanyou 63 to select the rice varieties of Yunnan round-grained rice 40
Hybridized for male parent, the kind through the pedigree seed selection of 6 generations, the rice varieties are not afraid of drought, be not afraid of flood, pest and disease damage is light, anti-fall
Ability is strong, well developed root system, and yield is high.
Embodiment
The technical scheme in the present invention is clearly and completely described below, it is clear that described embodiment is only
Several embodiments therein of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
Embodiment 1
A kind of suitable rice breeding method in fresh water level soilless culture, comprises the following steps：
(1) rice varieties of selection Yunnan round-grained rice 40 are maternal, the rice varieties of Shanyou 63 are that male parent is hybridized, and are harvested miscellaneous
Plant F1 generation paddy rice；
(2) the F-1 hybrids seed selfing is obtained into F2 for paddy rice；
(3) individual plant that plant forms are good, setting percentage is high is selected, continues selfing, more for seed selection, obtains F6 for paddy rice.
The F6 that breeding is obtained was sowed in the pond of Fusulinid Zoning for paddy rice March 25, and 6 are planted according to every mu of waters
Ten thousand plants or so of amount is planted.It need not be applied fertilizer in planting process, the root length of the kind is up to 60cm or so, and paddy rice can be straight
Meet the nutritional ingredient P and N etc. absorbed in waters.By test, setting percentage is up to more than 70%, 350 kilograms of per mu yield paddy rice.The grain of rice is excellent
Matter, main physical and chemical index reaches 2 grades of superior rice standards of national standard, and head rice rate is up to 65%.
In whole planting process, without irrigation, fertilising, spraying pesticide etc., management cost is greatlyd save.According to phase
Same implantation methods, (are tied compared to the mode (setting percentage 13%) of independent plantation Yunnan round-grained rice 40 or the mode of independent plantation Shanyou 63
Real rate 27%), the rice varieties obtained by the present invention can reach the requirement of large-scale promotion, with significant social value and warp
Ji value, also achieves significant technological progress.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
