Abstract
The invention provides a rice seedling stage growth accelerant and an application method thereof, and belongs to the field of an agricultural production technique. The rice seedling stage growth accelerant contains alpha-oxoglutarate and a surfactant, wherein the concentration of the alpha-oxoglutarate is 10-60g/kg and the concentration of the surfactant is 50-150g/kg. According to the rice seedling stage growth accelerant disclosed by the invention, the utilization efficiency of a nitrogen fertilizer of rice can be improved by 5.0-10.0%. The absorption and the utilization of the nitrogen fertilizer by the rice are improved and the accumulation amount of dry substances in a rice seedling stage is increased by 5.0-18.0%, so as to lay a good foundation for high yield of the rice. The absorption and the utilization of the nitrogen fertilizer by the rice are improved so that the application amount of the nitrogen fertilizer of the rice is reduced by 5.0-10.0%, the loss of the fertilizer is reduced, the cost of planting the rice is reduced, and an ecological environment is protected while benefits are increased.
Description
Technical field
The invention belongs to field of agricultural production technologies, be specifically related to a kind of rice seedling growth promoter and application process thereof.
Background technology
Nitrogenous fertilizer has very important effect in paddy growth, not only be nitrogen be in plant corpus important feature material as the constituent of protein, nucleic acid, chlorophyll etc., and the part of nitrogen or many endogenous hormones and enzyme, so the quality of Nitrogen Nutrition of Paddy Rice Plant, directly affect growing of paddy rice, and finally affect rice yield.The utilization ratio of current China nitrogenous fertilizer is common on the low side, only has about 30%-35%, after Irrigated paddy field uses N fertilizer, in a large number not by the nitrogenous fertilizer of rice absorbing, owing to running off and seepage effect and losing in the volatilization of ammonia in soil-water system, denitrification, surface.
The Nitrogen utility process done in object can be summarised as simply: plant root absorbs inorganic nitrogen, these inorganic nitrogens assimilate into amino acid or acid amides (trophism nitrogen AN) in root, leaf and seed, and AN is synthesized the constituent of various enzyme and the various structure of cell again further.In the originally assimilation process of inorganic nitrogen, α-ketoglutaric acid (α-oxoglutarate, α-OG) is a very important material.The approach of ammonia assimilation in organism, rice absorbing inorganic nitrogen must with NH
4 +form generates glutamic acid by glutamic dehydrogenase (GDH) and α-ketoglutaric acid; Or via GS/ GOGAT approach, first under glutamine synthelase (GS) acts on, synthesize glutamine with glutamic acid, then be glutamine and α-ketoglutaric acid generation 2 molecule glutamic acid under the effect of glutamate synthetase (GOGAT), glutamic acid then synthesizes other amino acid through transamination.No matter be GDH approach or GS/ GOGAT approach, α-ketoglutaric acid is all carbon skeletons of ammonia assimilation, therefore, is absorbed with important impact to N fertilizer.α-ketoglutaric acid is respiratory intermediate product, is formed in tricarbonic acid cycle by isocitric acid generation dehydrogenation, decarboxylic reaction.Correlative study shows, the enzyme that α-ketoglutaric acid is relevant to nitrogen metabolism, as nitrate reductase, nitrite reductase, GS have regulating action.
Example α-ketoglutaric acid being used for rice seedling growth promoter is had no in prior art.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme providing a kind of rice seedling growth promoter and application process thereof, this promoter by improving paddy rice absorbing nitrogenous fertilizer, can promote rice seedling growth.
Described a kind of rice seedling growth promoter, is characterized in that containing α-ketoglutaric acid and surfactant, and described α-ketoglutaric acid concentration is 10 ~ 60g/kg, and described surfactant concentration is 50 ~ 150 g/kg.
Described a kind of rice seedling growth promoter, it is characterized in that described α-ketoglutaric acid concentration is 15 ~ 55g/kg, described surfactant concentration is 60 ~ 140g/kg.
Described a kind of rice seedling growth promoter, it is characterized in that described α-ketoglutaric acid concentration is 20 ~ 50g/kg, described surfactant concentration is 70 ~ 130g/kg.
Described a kind of rice seedling growth promoter, it is characterized in that described α-ketoglutaric acid concentration is 25 ~ 45g/kg, described surfactant concentration is 80 ~ 120g/kg.
Described a kind of rice seedling growth promoter, it is characterized in that described α-ketoglutaric acid concentration is 35 ~ 40g/kg, described surfactant concentration is 90 ~ 110g/kg.
Described a kind of rice seedling growth promoter, is characterized in that described surfactant is one or more the mixture in sodium n-alkylbenzenesulfonate, lauryl sodium sulfate, alkene sulfonic acid sodium, sodium sulfate of polyethenoxy ether of fatty alcohol and alkanolamide.
The application process of described a kind of rice seedling growth promoter, to is characterized in that after rice tillering fertilizer is executed the 2nd day, and the rice seedling growth promoter 100g described in every mu of use carries out foliage-spray after adding the mixing of 50kg water.
Above-mentioned a kind of rice seedling growth promoter can improve the fertilizer utilization efficiency 5.0% ~ 10.0% of paddy rice.The present invention is by improving paddy rice absorbing nitrogenous fertilizer, and the accumulation of rice seedling dry matter increases by 5.0% ~ 18.0%, thus lays a good foundation for rice high yield; The present invention, by improving paddy rice to the absorption of nitrogenous fertilizer, can reduce nitrogen fertilizer for paddy rice amount of application 5.0% ~ 10.0%, reduces the loss of fertilizer, reducing the cost of Rice Cropping, preserves the ecological environment while improve effects.
