Abstract
The invention discloses a rice leaf green-keeping anti-freezing agent, and a using method and application thereof. The rice leaf green-keeping anti-freezing agent comprises gibberellin and brassinolide, wherein the weight ratio of gibberellin to brassinolide is (50-200):(0.025-0.10). The rice leaf green-keeping anti-freezing agent can also comprise chitosan oligosaccharide according to a certain ratio. When the rice leaf green-keeping anti-freezing agent is used, an aqueous solution form is adopted, wherein an aqueous solution is prepared from 50 to 200mg/L of gibberellin, 0.025 to 0.10mg/L of brassinolide and 100 to 300mg/L of chitosan oligosaccharide, and is applied to rice leaves in a spraying way during the full heading stage to milk-ripe stage of rice, and 30 to 45 liters of aqueous solution is applied to each acre. The rice leaf green-keeping anti-freezing agent can be applied to prevent the hazard of low temperature damage in autumn after the filling of late rice, has leaf anti-freezing and green-keeping effects as well as the effects of promoting the photosynthesis of the rice and retarding the aging of the leaves, has remarkable yield increasing effects, is a novel rice culturing technology capable of ensuring the high and stable yield of rice, and is suitable for popularization and application.
Description
Technical field
The present invention relates to plant growth conditioning material sphere, particularly, relate to a kind of rice leaf and protect green antifreezing agent, its using method and application.
Background technology
Paddy rice is the staple food crop of China, and rice is the staple food grain of Chinese 60% population, and approximately 50% peasant household is engaged in rice and produces, and it is China's the first farming that rice does.How the have a large population and a few land fundamental realities of the country of Shui Shaoshi China, utilize limited land resources and freshwater resources, ensures China's grain security, is the principal proposition that rice does scientific and technological progress.
The major weather disaster of restriction double cropping late rice stable high yield is autumn in summer arid before the neat fringe of safety and the Cold Dew wind of heading flowering period.Late rice heading flowering period, on the occasion of time early autumn, often causes violent cooling in the time that strong cold air is invaded, and affects the late rice flowering of normally earing.Therefore, low temperature becomes one of restriction late rice Key to high-yielding production meteorological factor.Large quantity research shows, between double cropping late rice heading flowering period, in the time that temperature is reduced to heading flowering Biological zero temperature, can cause heading flowering to be obstructed, and pollination and fertilization cannot normally be carried out, and ghost rate increases, thereby causes the significantly underproduction of late rice.
As far back as 70～eighties of 20th century, how to avoid Cold Dew wind risk for double cropping late rice, select reasonable date of seeding to carry out large quantity research.Since the nineties in 20th century, under Background of Global Warming, Cold Dew wind occurs to reduce to some extent, but Cold Dew wind had again the trend increasing in recent years.For this reason, the variation of the safe full heading time of research double cropping late rice, selects suitable sowing time, to before Cold Dew wind occurs, makes late rice reach the neat fringe of safety.But under current Climatic, the one, the restriction of paddy growth season and breeding time, the 2nd, extreme climate occurs often, almost unpredictable, affect more sensitive River for Cold Dew wind, how to utilize Cold Dew wind pests occurrence rule, select to be difficult to realize in suitable heading flowering period practical operation.So seek a kind of abnormal low temperature or the chemical control technique of Cold Dew wind harm in autumn of preventing, be to guarantee the safe full heading time of double cropping late rice, avoid or alleviate one of reliable method of Cold Dew wind impact.
Summary of the invention
The object of the present invention is to provide a kind of rice leaf to protect green antifreezing agent and using method thereof, to prevent abnormal low temperature or the freeze injury of Cold Dew wind to paddy rice in autumn.
Another object of the present invention is to provide a kind of rice leaf protects the application of green antifreezing agent.
For achieving the above object, the present invention adopts following technical scheme:
A kind of rice leaf is protected green antifreezing agent, comprises gibberellin, brassin lactones, calculates by weight ratio gibberellin: brassin lactones is 50～200:0.025～0.10.
Further, also comprise chitosan oligosaccharide, calculate by weight ratio gibberellin: brassin lactones: chitosan oligosaccharide is 50～200:0.025～0.10:100～300.
Further, calculate by weight ratio described gibberellin: brassin lactones: chitosan oligosaccharide is 150:0.05:150.
Above-mentioned rice leaf is protected the using method of green antifreezing agent, it is characterized in that, described rice leaf is protected green antifreezing agent and is adopted the aqueous solution, wherein, gibberellin is 50mg/L～200mg/L, brassin lactones is 0.025mg/L～0.10mg/L, sprays rice leaf in paddy rice full heading time～milk ripe stage, 30～45 liters every mu of consumptions.
Further, the described aqueous solution also comprises chitosan oligosaccharide 100mg/L～300mg/L.
Further, described gibberellin is 150mg/L, and brassin lactones is 0.05mg/L, and chitosan oligosaccharide is 150mg/L.
Above-mentioned rice leaf is protected green antifreezing agent, and to can be applicable to the guarantor of rice leaf green antifreeze.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention is mainly used in defending the harm of the rear Cold Dew wind of late rice grouting, except having the green effect of the antifreeze guarantor of blade, has promotion Rice Photosynthesis simultaneously, effect of Delaying Leaf-Senescence, and effect of increasing production is obvious, is that rice high yield stable yields rice makes new technology.
2, confirm through experiment, correctly use this rice leaf and protect green antifreezing agent, can significantly reduce abnormal low temperature or the freeze injury of Cold Dew wind to paddy rice in autumn, increase rice yield.
Embodiment
