Description
Technical field
The present invention is a kind of growth regulator dedicated to early rice, is used for long-grained nonglutinous rice morning in each paddy rice producing region, south, and the adjusting and controlling rice kernel grouting is dynamic, coordinates rice strain " Yuan Yiku " relation, thereby increases long-grained nonglutinous rice output early, improves its quality simultaneously.
Background technology
Early long-grained nonglutinous rice is a ripe the earliest listing paddy among a year, and China's long-grained nonglutinous rice sowing area morning reached 6,000,000 hectares in 2009, return to the level in 2004～2006 years, but the output aggregate level improved slowly.Early the long-grained nonglutinous rice maturation is on the occasion of high temperature season in China south, and kernel grouting speed is accelerated, and the grouting cycle shortens, and seed enriches bad, directly causes the reduction of output.Discover that the balance of seed endogenous hormones plays an important role to coordinating rice strain " Yuan Yiku " relation before and after the paddy rice heading.The basic element of cell division and indole-3-acetic acid content are lower in long-grained nonglutinous rice grain husk flower morning, seed and the sword-like leave before and after the heading, blade and root system early ageing, and seed storehouse vigor is lower.Abscisic acid strengthens the high-temperature resistance of blade on the one hand, slows down the inductive effect that high temperature forms rice quality; Can suppress leaf photosynthesis again on the other hand, reduce the supply of assimilation substance, it is bad to cause seed to enrich.Scientific worker's seed selection in the last few years a collection of two be rice variety morning that makes up between kind, though these subspecies combinations have big panicle many grains per panicle, the strong advantage of growth potential, but the problem that ubiquity seed circularity is low, the unfilled gtains rate is high, this has become the main limiting factor when seed selection research of this morning long-grained nonglutinous rice and application.Less abroad to this respect research, domestic a lot of scholar respectively from heredity, with many-sides such as synthetic relevant enzyme system of starch and endogenous hormones carried out a large amount of research (Wang Xi etc.: gibberellin and paclobutrazol reach influence to output to the adjusting of paddy rice " intergranular apical dominance ", 1999; Yang Jianchang etc.: ABA and GA are to the regulation and control of Grain Filling of Rice, 1999; Xiao's wave etc.: the relation of endogenous hormones and inter-subspecies hybrid rice kernel grouting, 2002; LI XUEMEI etc.: hybrid rice and parent's pustulation period seed and blade change of hormones, 2004; Huang Shengmou etc.: gibberellin and abscisic acid are to Grain Filling of Rice and solid influence, 2006; Yin Dynasty state equality: the application of plant hormone in the rice high yield cultivation, 2008), but because the restriction of various research meanses, obtained so far progress is also little, on producing, apply morning rice variety quantity also seldom, let alone it is carried out effective regulation and control.
The required cycle of genetic improvement is long, breed a kind and need spend great amount of manpower, financial resources and material resources, and existing many morning, its The Characters of rice variety was good, yield potential is big, and therefore taking the effective chemical regulation measure is to improve the quick of China's south early indica rice yield and quality and valid approach.Plant nutrition class chemical improvement agent has different effects to different cultivars, but the amplitude that improves is lower.Plant hormone class chemical improvement agent then has bigger regulating action, and it promotes plant hormone in vivo balance and coordination to a certain extent.Liu Lijun is a material with the Different Types of Rice kind, sprays 6-BA in fringe phase beginning, can obviously improve the circularity of seed, ear to ripening period in paddy rice, the foliage-spray phytic acid helps the active raising of amylosynthease, suppresses hydrolytic enzyme activities, helps kernel grouting.Though chemical regulator has been widely used in during agricultural herd in China, do not see the report of relevant early indica rice growth regulator so far.
Summary of the invention
