Description
Technical Field
The invention relates to the technical field of agricultural improved varieties, in particular to a method for cultivating dry-planting rice seeds.
Background
The rice is one of the main grain crops in China and plays an important role in grain production, so that the rice yield is increased, the rice planting area is enlarged, and the rice is very important for ensuring the grain safety. At present, the main planting mode of rice in China is mainly paddy field planting, the planting conditions are complex, the requirement is high, and the planting and the yield of the rice are affected. Especially in the north, due to the limitation of natural conditions, the rice planting has large demand for moisture, higher irrigation cost and difficult management.
Disclosure of Invention
The invention aims to provide a cultivation method of dry-land rice seeds, and the rice seeds which can be directly sown in dry lands can be produced by hybridization, so that the requirement of rice planting is reduced, the rice planting cost is saved, and the rice yield is improved.
In order to realize the purpose, the following technical scheme is provided:
a method for cultivating dry-planting rice seeds comprises a layout method of rice planting areas and a cross breeding method:
the layout method of the rice planting area is a method for surrounding a dry land by a paddy field, and comprises the following steps:
s1: selecting a farmland, weeding, renovating, adding a soil conditioner into the farmland, and removing residual fertilizer and pesticide in the farmland to serve as a rice planting area;
s2: dividing a planting area into two areas, including a dry farmland area and a paddy field area, wherein the dry farmland area is positioned in the center of the whole planting area, the paddy field area surrounds the dry farmland area, is distributed around the dry farmland area and is separated from the dry farmland area through a ridge, and the area ratio of the dry farmland area to the paddy field area is 1: 1;
s3: and irrigating and storing water in the paddy field area to make the water surface 5-10 cm higher than the planting area, and not irrigating in the dry field area.
The cross breeding method comprises the following steps:
a: pretreating a seedling raising field: weeding the seedling raising field, moistening soil after 2-3 days, and then renovating to ensure that the humidity of the soil is between 6% and 10%;
b: seedling culture: selecting full-grain rice seeds, sowing the rice seeds in a seedling raising field every 5cm, constructing a greenhouse in the seedling raising field after sowing, and removing the greenhouse after 35-40 days;
c: field management before seedling transplanting: draining the paddy field area 1-2 days before transplanting seedlings, and controlling the height of the water surface to be 1-3 cm;
d: transplanting seedlings: selecting rice seedlings with good growth vigor, and transplanting the rice seedlings to a planting area according to the distance of one rice seedling per 5 centimeters;
e: field management during growth: keeping the water flow circulation of the paddy field area and controlling the water surface to submerge the seedling roots by 2cm-5 cm; properly irrigating the dry farmland to ensure that the moisture content of the dry farmland is between 40 and 45 percent;
f: fertilizing: fertilizing the planting area 8-9 days after the seedlings are transplanted, and weeding in the rice growing process;
g: pollination and hybridization: in the heading and flowering period of rice, the wind and insects are used for pollen transmission, so that the rice is naturally pollinated and hybridized;
h: harvesting: when the rice ears of the hybridized rice are drooping and golden and full, the rice in the dry land area and the rice in the paddy field area can be respectively harvested, and seeds are respectively collected and stored;
i: seed selection: selecting rice seeds harvested in dry farmland, namely dry-planted rice seeds.
Preferably, the dry farmland area is surrounded by the paddy field, so that the moisture content is sufficient, and the moisture requirement can be met only by proper irrigation.
The invention has the following beneficial effects:
according to the invention, the layout and area ratio of the rice dry-field planting area and the rice paddy-field planting area are skillfully and reasonably designed, pollination and pollination are carried out by utilizing natural conditions, rice hybridization is realized, rice seeds which can be directly sowed in the dry field are obtained, the requirement of the rice planting on water is greatly reduced, the irrigation cost is reduced, meanwhile, the rice seeds obtained by the method can be directly sowed in the dry field, the steps of rice planting are simplified, and manpower and material resources are saved. The method is simple, low in cost and easy to widely spread and apply.
Detailed Description
The present invention will be described in detail with reference to examples.
