Abstract
The invention discloses a kind of breeding methods of dry~sowing paddy seed, the method for layout method and crossbreeding including Rice Cropping region.The layout and area ratio that the present invention passes through ingenious reasonable design rice dry land growing area and paddy planting area, and utilize natural conditions pollination, pollination, realize paddy rice cross breeding, demand of the Rice Cropping to moisture can be greatly reduced, reduce irrigation cost directly in the rice paddy seed of dry land sowing by obtaining, simultaneously, the rice paddy seed obtained using the present invention can save human and material resources directly the step of dry land is sowed, simplifies Rice Cropping.The method of the present invention is simple, and cost is relatively low, is easy to wide-scale distribution and application.
Description
Technical field
The present invention relates to the technical fields of agriculture breeding, and in particular to a kind of breeding method of dry~sowing paddy seed.
Background technique
Rice is one of China's staple food crop, is occupied an important position in grain-production, therefore, improves rice and produces
Amount expands Monitoring of Paddy Rice Plant Area, for guaranteeing that grain security is extremely important.Main planting patterns of the rice in China is main at present
It is paddy planting, planting conditions are complicated, it is desirable that it is higher, so that the plantation of rice and yield are all affected.Especially in the north, by
Big to moisture content demand in the plantation of the limitation of natural conditions, rice, irrigation cost is higher, not manageability.
Summary of the invention
It is an object of the present invention to which hybridization is produced can be straight by providing a kind of breeding method of dry~sowing paddy seed
The rice paddy seed in dry land sowing is connect, to reduce the requirement of Rice Cropping, Rice Cropping cost is saved, improves rice yield.
To realize this purpose, the following technical schemes are provided:
A kind of breeding method of dry~sowing paddy seed, the side of layout method and crossbreeding including Rice Cropping region
Method:
The layout method in Rice Cropping region is the method that paddy field surrounds dry land, comprising the following steps:
S1: choosing one piece of farmland, and soil conditioner is added in weeding, renovation in farmland, removes remaining chemical fertilizer in farmland
Pesticide, the growing area as rice；
S2: growing area is divided into two regions, including dry land area and paddy field area, the dry land area is located at entire growing area
Center, the paddy field area surrounds dry land area, is distributed in the surrounding in dry land area, and is distinguished by ridge and dry land every the drought
The area ratio in field area and paddy field area is 1:1；
S3: irrigating paddy field area, water storage, and the water surface is made to be higher by growing area 5cm-10cm, does not irrigate dry land area.
The method of crossbreeding includes the following steps:
A: nursery field is pre-processed: weeding is carried out to nursery field, moistens soil after 2-3 days, then renovates, guarantee soil
Humidity is between 6%-10%；
B: nursery: choosing the rice paddy seed of full grains, is sowed according to every 5 centimeters one in nursery field, after planting
Greenhouse is constructed on nursery field, removes greenhouse after -40 days 35 days；
C: the field management before transplanting seedlings: until 1-2 days before transplanting seedlings, draining paddy field area, controls water surface elevation 1cm-
3cm；
D: shoot transplanting equipment: choosing the rice seedling to grow fine, according to every 5 centimeters one distance, is transplanted to growing area；
E: the field management during growth: the circulation of paddy field area water flow is kept, and controls the water surface and did not had rice shoot root
2cm-5cm；Dry land is suitably irrigated, makes dry land moisture content between 40%-45%；
F: it fertilising: 8-9 days after shoot transplanting equipment, applies fertilizer to growing area, and carries out weeding in rice developmental process；
G: pollination, hybridization: in the heading flowering period of rice, pollen transmission is carried out using wind and insect, awards rice naturally
Powder, hybridization；
H: harvesting:, can be to dry land area rice with paddy field area rice point when the rice spike of rice after hybridization is sagging, golden yellow full
It is not gathered in, seed is collected respectively, is stored；
I: seed selection: the rice paddy seed of selection dry land harvest, as dry~sowing paddy seed.
Preferably, due to being surrounded by paddy field, moisture content is sufficient in the dry land area, and only need to suitably irrigate can meet moisture
It is required that.
The advantageous effect of present invention is that:
The present invention by it is ingenious it is reasonable design rice dry land growing area and paddy planting area layout and area ratio, and
Using natural conditions pollination, pollination, paddy rice cross breeding is realized, obtaining can drop significantly directly in the rice paddy seed of dry land sowing
Low demand of the Rice Cropping to moisture reduces irrigation cost, meanwhile, it can be directly in drought using the rice paddy seed that the present invention obtains
The step of field is sowed, and Rice Cropping is simplified, saves human and material resources.The method of the present invention is simple, and cost is relatively low, is easy to extensive
It propagates and applies.
Specific embodiment
The present invention is described in detail with reference to embodiments.
