The present invention relates to a kind of preparation of regulating crop growth, particularly can make high bar crops dwarfing and resist down excellent preparation.
Long-stalked crop comprises wheat, corn, jowar, millet etc., these crops especially wheat, corn occupy critical role in China's grain-production, high yield in recent years facts have proved, the corn yield increasing potentiality are very big, but corn is as long-stalked crop, its lodging problem is not well solved for a long time, and under the condition of dense planting, it is more outstanding to lodge." the corn robust element " of Chu Shouing mainly contains its defective of ethrel and is that this medicine can only take out male phase beginning at corn and spray in the market, so elongation unrestraint effect to corn bottom internode, can only suppress the elongation of fruit ear top internode, finally cause the top internode to shorten, the intensive cap shape that is of blade, such plant type not only ventilation and penetrating light is bad, and it is top-heavy, easier lodging, simultaneously owing to be spray medicine when milpa is tall and big, make troubles for the dispenser operation, particularly mechanized more can't be carried out.
The plant growth retardent that widely used both at home and abroad at present " chlormequat " is a kind of synthetic, plant growing had retarding action, this " chlormequat " is used to prevent that the wheat lodging from having certain effect, but to barley, oat lodging, effect is then not obvious, corn is lodged then effect is poorer, because it is a kind of plant growth retardent, so when preventing to lodge, can cause the crop fruit ear to diminish inevitably and cause the underproduction.
The object of the invention is to overcome the deficiency of above-mentioned " robust element " " chlormequat " and so on medicine, provide a kind of according to the long-stalked crop growth and development characteristics, take effective chemical control means, regulate some physiological and biochemical procedure of inside plants, making it that physiological take place downgrades, it is resistant to lodging thereby reach, and a kind of long-stalked crop that helps increasing production purpose is again downgraded lodging resistance agent.
The present invention is a kind of compound that contains the number of chemical composition, and its physiological action of these chemical compositions is not quite similar, and the composition that has can delay the cell elongation growth, but can promote the cell horizontal expansion, and the chemical composition that has then promotes the formation and the elongation of adventive root or lateral root; And the other chemical composition has the activity that improves some enzyme in the plant corpus, regulates the biosynthesis of ethene, effects such as generation and raising photosynthetic efficiency.Therefore, physiological function of the present invention is many-sided, and its main effects is the elongation by intercalary meristem's cell of control internode, cause the dwarfing of long-stalked crop plant, promote the cell horizontal expansion simultaneously, increase the cane rugosity, promote root system early to send out, increase the root amount.Improve chlorophyll content, delay functions such as leaf senile.
The present invention seeks to implement by following proposal, promptly this dwarf and resistance to lodging agent for long-stalked crops main component comprises the chlormequat of rational proportion, ethrel, the nitrogen propylhomoserin, methyl, components such as gibberellin, chlormequat wherein is in order to delay the elongation of plant internodal cell, the growth that ethrel is not only capable of inhibiting cell, also can promote the cell horizontal expansion simultaneously, both composite applications just can make the stem of plant downgrade sturdy, tough and tensile, methyl and gibberellin effect are the activity of ethylene synthetase in the adjustable joint plant corpus, the nitrogen propylhomoserin (the nitrogenous propylhomoserin of the present invention) that its external source is imported changes into more ethene, thereby delay the growth of plant, methyl also has the growth that promotes plant adventive root and lateral root in addition, root system of plant is early sent out, the root amount increases and is flourishing, flourishing root system helps plant on the one hand and better absorbs nutrition in the soil, can play the set effect to plant on the other hand, resistant to lodging, gibberellin then can improve plant photosynthesis efficient, therefore dwarf and resistance to lodging agent for long-stalked crops provided by the present invention is a kind of long-stalked crop dwarfing and preparation resistant to lodging of making, owing to solved the lodging problem of long-stalked crop effectively, so on this basis, can realize the dense planting of long-stalked crop, dense planting can be increased production, in addition, more photosynthetic product is migrated aspect the plant reproductive growth, can promote growing of fruit ear, to reach big panicle many grains per panicle, the volume increase purpose that grain is full, in addition, said preparation also can add the essential nutrition of an amount of plant growing (as N, P, K, Zn etc.) to satisfy the needs of crop growth.The degree of dwarf and resistance to lodging agent for long-stalked crops key component provided by the invention is: chlormequat 10-30%, ethrel 10-50%, nitrogen propylhomoserin 10-40%, methyl 0.1-2%, gibberellin 0.01-1%, for increasing requisite nutrient component in the long-stalked crop production process, can add an amount of N or P in addition according to the difference of different long-stalked crop desired nutritional compositions and different soil property needs
