Description
The present invention relates to improve the conditioning agent of setting percentage of hybrid rice.The large spike high-quality hybrid rice that China cultivates has the unfilled gtains about 20%, if address this problem, can improve the output of large spike hybrid rice 20%.
Held the 3rd the international agricultural science and technology annual meeting of China on April 12nd, 1999, theme: plant protection and plant nutrition in Beijing.In current meeting; the paper of Mr. Tao Longxing of China Paddy Rice Inst report is " physiological action and the paddy rice chemical control of " the grain grain is full " increase a year technology "; reported in the literary composition: large spike combination unfilled gtains occurs in the base portion of fringe; when the paddy rice heading is bloomed; the Xiao Hua on fringe top has stronger competitive advantage; and the higher hormonal readiness of tool; preferential grouting; weak tendency flower to base portion produces depression effect; make weak tendency can not start the filling oar; have only when the grouting of surging grain reaches certain level, the grouting of the weak grain of gesture could start, at this moment the root system of paddy rice; sword-like leave senesces; imbalance between supply and demand between the master of source, storehouse is outstanding day by day to have caused a lot of weak tendency grains can not normally irritate oar; (Sinology can be edited to become unfilled gtains; plant protection and plant nutrition progress; Chinese agriculture publishing house, in April, 1999,375-377 page or leaf)." the grain grain is full " design principle: 1. root system health care delays senility.Paddy rice back root is strong full of leaves, improves photosynthetic efficiency, blue or green bar yellow maturity; 2. hormonal balance is promoted and is irritated oar.Regulate paddy rice and irritate the balance of IAA in the oar phase seed, the balanced oar of irritating, the grain grain is full.Mr. Yin Taolongxing does not make clear, the main cause that the large spike setting percentage of hybrid rice is low, and " the grain grain is full " of development can only improve ripening rate 5-8%.
The purpose of this invention is to provide a kind of conditioning agent that improves setting percentage of hybrid rice.
The inventor is to the heading of large spike hybrid rice, flowering, irritate oar and solid overall process, carrying out exploratory development in several years finds: not only have above-mentioned large spike hybrid rice tassel top IAA (heteroauxin) hormone-content higher, tassel bottom IAA (heteroauxin) hormone-content is lower, the situation of more unfilled gtains is arranged at the tassel bottom, also have that the hybrid rice tassel is top a unfilled gtains, top small ear base portion also has 1～3 sky not plump, bottom small ear base portion has the situation of 3～8 unfilled gtainses, this illustrates that each small ear top IAA hormone-content is higher lower with bottom IAA hormone-content in the big fringe, and the big top IAA hormone-content of fringe is too high.After the hybrid rice yellow maturity harvesting, the rice root still has very strong vitality, under the condition of the temperature that is fit to, rich water, can go out rice seedling, growth, heading by high tiller, flowering, solidly grows the regrowth hair rice.These phenomenons prove absolutely that large spike hybrid rice bottom unfilled gtains is many, are not that the aging of rice root causes, limit causes but the inborn Physiology and biochemistry of large spike hybrid rice lacks.
The inventor studies show that in several years: the large spike hybrid rice has that growth is vigorous, output is high, rice matter good advantage, but need the high-quality nutriment in the growth middle and later periods, particularly nutritive elements such as nitrogen, phosphorus, potassium, calcium, zinc, copper and boron have very big activation to the plurality of enzymes that can promote growth in the large spike hybrid rice body.Make and to promote in the large spike hybrid rice body that the content of the endogenous hormones (growth table, the basic element of cell division and gibberellin) of growth increases.Growth hormone, the basic element of cell division, gibberellin, calcium, zinc, copper and boron are to the polyvoltine of rice flower organ, growth and solid important effect arranged.According to large spike hybrid rice Physiology and biochemistry characteristics, the conditioning agent of the raising setting percentage of hybrid rice that inventor's research and design goes out, enter several nutritive elements that growth hormone and urgent need can be provided in the rice strain body, the activity that again can activation energy promotes the plurality of enzymes of growth, interior endogenous hormones (growth hormone, the basic element of cell division and the gibberellin) content of body is increased sharply, regulate the growth hormone balance simultaneously, promote the differentiation of rice strain floral organ, growth and solid, improve the paddy rice ripening rate.
According to purpose of the present invention, growth hormone in the body during heading of large spike hybrid rice, the basic element of cell division and GA content are lower, blooming stage prolongation, the differentiation of fringe base portion floral organ, growth and solid characteristics of being obstructed, after try out in test and field for many years, work out the conditioning agent that improves setting percentage of hybrid rice, it is characterized in that: contain and account for conditioning agent total weight percent 0.15%～0.61% auximone, 39.4%-51.5% urea, the real agent of the short bow structure of 37.9%-50%, 6.1%-10.6% auxiliary agent.
Contain very important active substance-auximone in the conditioning agent of the present invention, it has the effect of a lot of physiological chemistry of plants and molecular biology of plants, DNA-histone complex can " be pried open " or the dna double spiral shell is opened, impel RNA polymerase to connect, further cause the synthetic of novel protein (enzyme), cause the persistence growth, it is caducous that auximone can make flower avoid, hybrid rice pollen vigor can only be kept a few minutes, growth hormone and gibberellin are the promoter of pollen germination and pollen tube growth, the flower after fertilization, the each several part growth hormone content of gynoecium increases a lot, the synthetic district of 20 hours growth hormone mainly occurs in the style top, and synthetic district moved on to the style base portion in 50 hours, and 90 hours when pollen arrival ovule, gynobase just becomes the synthetic main place of growth hormone.Therefore, supplemented with exogenous growth hormone and promotion endogenous growth are plain synthetic, to the differentiation of hybrid rice organ, growth and solid significant.
Nitrogen is the component of many organic compounds in the plant corpus, for example protein, nucleic acid, chlorophyll, enzyme, vitamin, alkaloid and the basic element of cell division.The late growth stage of rice nitrogen stress shows as that fringe is short and small, kernal number is few, hollow kernels, and be prone to early ageing and cause the underproduction.Zeatin is the main basic element of cell division in the paddy rice body, heading stage, applied nitrogen can make the interior zeatin content of paddy rice body significantly go up, thereby obtain delaying the degradation speed of chlorophyllinite albumen and improve photosynthesis, nitrogen stress then can cause paddy rice overground part cell division cellulose content and active decline, early ageing occurs.
It is that to form cation that the water-soluble back of these materials forms and anion all be the activator that can promote the plurality of enzymes of growing in the plant corpus for plurality of inorganic salt, complex salt, inner complex salt and other compound that the present invention improves the real agent of short bow structure in the conditioning agent of setting percentage of hybrid rice, enter after the plurality of enzymes that promotes growth in the paddy rice body is activated, endogenous growth element, the basic element of cell division and gibberellin are increased sharply.The real agent of short bow structure again with the paddy rice body in growth hormone, the basic element of cell division and gibberellin promote floral organ differentiation, growth and solid together, impel leaf carbohydrate, protein and mineral matter to transport to seed, make the grain of rice fuller.
Phosphorus is the necessary component of nucleic acid, and RNA has the activity of the basic element of cell division.The P elements trophic level will influence the cell division cellulose content in the plant corpus, and cell division and phosphorus can promote floral organ differentiation, growth and solid, promote the leaf carbohydrate to transport to the grain of rice.
Potassium is synzyme in the plant corpus, the activator of oxidoreductase and transferase three major types 60 plurality of enzymes, can promote the transportation of starch and protein synthesis and growth hormone, potassium can delay chlorophyllous destruction and prolong the functional period of functional leaf, has to prolong the effect that seed is irritated the oar time and increased thousand kernel weight.
Calcium is the activator of plurality of enzymes in the plant corpus, promotes the stable of cell wall and plasmalemma structure, promotes the growing tips of the plant continued growth, C
a 2+Regulating action by the pair cell membrane permeability can weaken the synthetic of ethene, thereby delays senility; The growth of pollen tube also is subjected to the stimulation of calcium, and calcium is the chemotactic main inducement of pollen.
Zinc can promote growth hormone synthetic, can activate the activity of the plurality of enzymes of synthetic protein, can improve plant corpus inner gibberellin content, and paddy rice and corn are the most responsive to zinc.
Copper is the activator of plant plurality of enzymes, is again the promoter of development of floral organs, when paddy rice lacks copper, can not ear or the fringe shrinkage deformation when serious, and the low or hollow kernels of ripening rate, even not solid.
Boron can promote the synthetic and growth hormone of nucleic acid and protein and the transportation of sugar; Boron can improve the oxidasic activity of growth hormone (IAA), promotes the growth hormone diffusion, avoids the too high and harm that causes of plant corpus office growth hormone; Boron can promote building up of reproductive organs and grow, and promotes the sprouting and the pollen official elongation of plant pollen, improves floral organ fertilization rate and seed-setting rate; Boron mixes with urea uses the content of plant corpus inner gibberellin significantly.
Scientific research proves: carbohydrate containing, the various macroelement of grease and trace element, growth hormone, gibberellin and ethene in the pollen; Change of hormones in the seed forming process: what at first occur is the basic element of cell division, the fission process of seed is built up in adjusting, be gibberellin and growth hormone then, regulate organic matter to seed transportation accumulation, abscisic acid rolls up between the seed maturation simultaneously, abscisic acid impels the seed maturation and stops to irritate oar, after paddy rice enters heading, growing point is at tassel, from floral organ differentiation, flowering, fertilization, filling oar to the process of seed, capacity and balanced growth hormone must be arranged, just can finish under the basic element of cell division and the gibberellin effect.Particularly irritate the oar phase, the content of growth hormone, gibberellin and the basic element of cell division reduces gradually along with time lengthening, and the content of abscisic acid and ethene increases gradually along with time lengthening, and it is long more that seed is irritated the oar time, the efficient of storage starch, protein and ester fat is high more, and seed is full more.Growth hormone, gibberellin and the decay of cell division cellulose content can make the efficient of irritating oar time lengthening and storage starch, protein and ester fat improve slowly in the seed; Abscisic acid and ethylene contents increase soon in the seed, and the efficient that shortens when irritating oar with storage starch, protein and fat is reduced.
Ear to solid characteristics according to above-mentioned big fringe hybrid rice, the peculiar function and the effect of element in the real agent of auximone, urea and short bow structure, research and design goes out the conditioning agent of the raising setting percentage of hybrid rice of being made up of the real agent of auximone, urea and short bow structure.This conditioning agent not only has three kinds of Main Ingredients and Appearance addition effects of the real agent of auximone, urea and short bow structure, also has the prior effect that multiplies each other.
