Abstract
The invention discloses a rice two-line sterility line propagation method and belongs to the technical field of rice propagation. The method comprises the following steps that a, seeds are sown in the suitable period, wherein the rice two-line sterility line fertility sensitive period is scientifically planned, seeds are sown on about July 10, and the fertility sensitive period is from September 5 to September 12; b, the rice is covered with a greenhouse film to increase temperature in the heading and blooming stage, wherein heading is started from about September 20, and the rice needs to be covered with the greenhouse film to increase temperature; c, a heating device is added for heating in the grain filling stage, wherein a coal stove is used for heating in the film greenhouse at night from October 15 to November 10; d, harvesting is carried out, wherein sterile line seeds can be harvested when becoming yellow and mature at about November 11. The rice two-line sterility line propagation method has the advantages of being high in yield, short in growth period and particularly suitable for rice two-line sterility line breeding material generation adding and core seed expanding propagation.
Description
Technical field
The present invention relates to a kind of two-line sterile line of rice propagation method, belong to Oryza sativa L. reproduction technique field.
Background technology
Two-line sterile line of rice is a kind of special light temperature-sensitive rice, and specifically: this Oryza sativa L., under long-day, hot conditions, shows as male sterility, at this moment it as sterile line, can be hybridized with restorer, produces hybrid seed. Two-line sterile line of rice breeding has a lot of method, as bred at Hainan in Winter; At high altitude localities, province Wheat summer sowing such as Yunnan; Can also pass through at two-line sterile line of rice fertility sensitive multiplication in period etc. summer in province, south. Difference due to geographical conditions, it is necessary to the method constantly adjusting two-line sterile line of rice breeding, to adapt to the condition of different geographical, reaches the purpose of high yield, low cost.
Summary of the invention
The technical problem to be solved is in that to provide a kind of two-line sterile line of rice propagation method, and its yield is high, and growth cycle is short, is particularly suitable for Middle Eastern, Anhui two-line sterile line of rice breeding material and adds generation and core seeds expanding propagation.
The technical problem to be solved takes techniques below scheme to realize:
A kind of two-line sterile line of rice propagation method, it comprises the following steps:
A, proper seeding: scientific arrangement two-line sterile line of rice fertility sensitive period, sowing in about 10 days July, fertility sensitive period was 5 days-JIUYUE of JIUYUE 12 days;
B, heading flowering period cover greenhouse film increases temperature: JIUYUE starts heading for about 20 days, need to cover greenhouse film to increase temperature;
C, grouting parameter increase heating equipment and heat: during 15-November 10 in October, briquet stove heating at night in thin film booth, place a common coal stove for every 15 square metres, 3 lump coal balls put into by each coal stove, coal stove air inlet to be sealed up, spontaneous firing, and night is without adding coal cinder;
D, sowing: on November about 10, male-sterile seed yellow maturity can be gathered in the crops.
In described step b, heading flowering period need to be sprayed 2 times with jingganmycin, prevents and treats banded sclerotial blight.
In described step b in greenhouse film noon on daytime temperature less than 35 DEG C.
The invention has the beneficial effects as follows: the present invention utilizes nature light and temperature condition to breed two-line sterile line of rice at Anhui Province's Chuzhou City.Yield is high, and growth cycle is short, is particularly suitable for two-line sterile line of rice breeding material and adds generation and core seeds expanding propagation.
Detailed description of the invention
In order to the technological means of the present invention, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with specific embodiment, the present invention is expanded on further.
Embodiment 1
A kind of two-line sterile line of rice propagation method, it comprises the following steps:
A, proper seeding: scientific arrangement two-line sterile line of rice fertility sensitive period, sowing in about 10 days July, fertility sensitive period was 5 days-JIUYUE of JIUYUE 12 days;
B, heading flowering period cover greenhouse film increase temperature: JIUYUE within about 20 days, start heading, greenhouse film need to be covered to increase temperature, if in greenhouse film noon on daytime temperature to take off more than 35 DEG C film dispel the heat, normally cover At All Other Times;
C, grouting parameter increase heating equipment and heat: during 15-November 10 in October, briquet stove heating at night in thin film booth, place a common coal stove for every 15 square metres, 3 lump coal balls put into by each coal stove, coal stove air inlet to be sealed up, spontaneous firing, and night is without adding coal cinder;
D, sowing: on November about 10, male-sterile seed yellow maturity can be gathered in the crops.
Spraying 2 times at heading flowering period domestic demand jingganmycin, preventing and treating Oryza sativa L. suffers from banded sclerotial blight.
The present invention utilizes nature light and temperature condition to breed two-line sterile line of rice at Anhui Province's Chuzhou City. Yield is high, and growth cycle is short, is particularly suitable for two-line sterile line of rice breeding material and adds generation and core seeds expanding propagation.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described. Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention. Claimed scope is defined by appending claims and equivalent thereof.
