Description
Technical field
The invention belongs to agricultural technology field, for Rice Flowering to ripe irrigation, and in particular to one kind promotes paddy rice
Spend assimilation quotient in rear stem transported to seed and kernel grouting irrigation method.
Background technology
Grain Filling of Rice is the final stage of yield composition, and the quality of Grain Filling directly determines grain weight and yield
Just.Photosynthesis assimilation product needed for cereal crops kernel grouting is from two aspects：Stored before spending rear photosynthesis and blooming
Assimilation quotient (predominantly starch and soluble sugar) in stem (cane+leaf sheath).The assimilation quotient being stored in before spending in stem is not only
One part of kernel grouting material, and be the important substance basis for starting grouting, its transport velocity and transhipment amount or so
Kernel grouting speed, and then influence grain weight and ultimate output (Yang Jianchang, China Agricultural University's thesis for the doctorate, 1996).Part is existing
For high-yield variety, particularly large spike Super Hybrid rice varieties, or under high nitrogen level, assimilation quotient is operated to seed in rice stem
Measure that small, kernel grouting is slow, low setting percentage is outstanding problem (Yang and Zhang, New in Rice Production
Phytologist,2006,169:223-236；Journal of Experimental Botany,2010,61:1-5).In the past
Though there is the report that paddy rice and Wheat in Grain Filling Stage can promote the assimilation quotient stored in stem to be operated to seed by soil drought
(Austin et al.Annals of Botany, 1980,45:309-319；Kobata et al.Crop Science,
1992,32:1238-1242；Gebbing et al.Plant Physiology, 1999,121:871-878), but in usual feelings
Under condition, soil drought can reduce photosynthesis, and suppress substance transportation increase in kernel grouting, the stem as caused by soil drought must
The mistake of photosynthesis reduction can not be compensated, grain weight and yield reduction (Bidinger et al.Nature, 1977,270 is caused:
421-433；Chaves and Oliveita, Journal of Experimental Botany, 2004,55：2365-2384；
Barnabas et al.Plant Cell&Environment,2008,31:11-38).Lacking at present to promote in rice stem
Assimilation quotient is transported to seed, can be promoted kernel grouting again and be improved the technology of setting percentage.
The content of the invention
In order to overcome the deficiencies in the prior art, assimilation quotient transhipment and seed in the rear stem of paddy rice are promoted the invention provides one kind
The irrigation method of grain grouting.

Problem.Its principle is to be regulated and controled according to assimilation quotient transhipment and kernel grouting in the rear stem of paddy rice by soil moisture, according to paddy rice
Grouting time and soil types, it is determined that needing leaf water potential index or the soil water-containing figureofmerit irrigated, carry out accurate moisture pipe
Reason, falls dry spell in soil, does not substantially suppress photosynthesis, photosynthesis can be promoted in the rehydration phase, water management is promoted
Enter to spend assimilation quotient in rear stem to be transported to seed, kernel grouting speed can be increased again, improve setting percentage and grain weight, and then improve yield
And WUEL.
