The invention relates to the technology of delaying growth of plants and discloses an old and famous tree growth retardant, a conveying method thereof and a conveying device thereof. The old and famous tree growth retardant mainly comprises paclobutrazol, chlormequat chloride, daminozide and water and inhibits the biosynthesis of GA in plant bodies to inhibit the growth of plant sub-apical meristems, delay the elongation and growing speed of cells and then delay the growth. The growth retardant is injected into the tree bodies through a conveying device with simple and safe operation, and theenvironments and safety of special occasions, such as classical gardens and the like, are ensured. A cylindrical sponge body of an absorber is embedded in a tree trunk, so the maximal absorption areais achieved after the retardant is infused into the tree trunk, the retardant can be uniformly and quickly diffused into conveying and guiding tissues on the peripheral surfaces of round holes, the absorption of the infused liquid is quickened. The liquid in the holes can be effectively prevented from losing due to a rubber hole plug of the absorber, so the utilization efficiency of the retardantis improved.

The invention provides a shoot control and flower promoting composite conditioning agent special for loquat trees. The composite conditioning agent is prepared from the following raw materials by weight: 30g-60g of paclobutrazol, 20g-40g of daminozide, 30g-60g of chlormequat chloride, 90-150g of potassium nitrate, 0.1g-0.8g of compound sodium nitrophenolate, and 0.5g-2g of a pigment. The component raw materials are crushed, sieved by a 100-mesh sieve and then mixed, thus obtaining the composite conditioning agent. According to the technical scheme provided in the invention, the composite conditioning agent can achieve good flower bud differentiation promoting and control effects, and basically can promote the conversion of each loquat tree branch from vegetative growth to reproductive growth, thus increasing the flowering rate of loquat trees and enhancing the yield. The composite conditioning agent provided in the invention has the advantages of high efficiency, low toxicity, no residue, no side effect, long use period, and wide use concentration range, etc.

The invention relates to a plant growth regulator composition containing maleic hydrazide and the purposes thereof. The composition contains maleic hydrazide (A) and a combination of known plant growth regulators, such as paclobutrazol, uniconazole, cycocel, mepiquat chloride, triapenthenol, daminozide, ethephon, taterpex and thidiazuron, wherein the weight ratio of the (A) to the (B) is 1: 300 to 500:1 and preferable 1:100 to 300:1, the (A) and the (B) can be proportioned with known aids and an excipient to prepare any agriculturally acceptable preparation; and the agriculturally acceptable preparation can be diluted with water or soil into a needed concentration of 1-8000 mg / kg, preferable 50-5000 mg / kg and used for regulating the growth of cultured plants, such as hedge plants, lawns, landscape plants, fruit trees, vegetables, economic crops, food oil crops and forage grass through the treatments of irrigation, flood irrigation, fertilization with water, jetting, spraying, scattering, smearing, injecting, transfusing, dressing seeds, spreading fertilizer, dispersing, and the like. The composition has the advantages of wide range of applications, low cost, good effect and synergy.

The invention relates to an analytic method for remnant unsymmetrical dimethylhydrazine in daminozide. The method using formaldehyde as derivating agent includes the steps: preparing standard unsymmetrical dimethylhydrazine solution, drawing a standard curve, preparing to-be-detected sample solution, sequentially infiltrating the prepared to-be-detected sample solution into a chromatograph, recording a peak area, substituting the peak area into the standard curve to obtain a UDMH (unsymmetrical dimethylhydrazine) remnant value, and the like. The method solves the technical problem that using conventional analytic methods is difficult to detect trace remnant unsymmetrical dimethylhydrazine in daminozide, and is significant to production and quality control of daminozide products.

The invention discloses a plant growth regulation composition, a plant growth regulation preparation and applications of the plant growth regulation composition and the plant growth regulation preparation, wherein the plant growth regulation composition comprises 2-(acetoxy)benzoic acid and daminozide according to a weight percentage ratio of 1:(0.5-10). With the plant growth regulation composition and the plant growth regulation preparation of the present invention, the chlorophyll content of the leaf can be increased, the plant height can be restrained, the root dry weight and the inflorescence number can be increased, the flowering time can be prolonged, the chrysanthemum can be prevented from presenility or lodging, the risk of the occurrence of presenility due to the use of the plant growth delaying agent can be reduced, and the problems of narrow application, strong crop selectivity, unsatisfied effect, and high phytotoxicity risk of the single plant growth regulation agent can be solved.

The invention provides a plant growth regulator for delaying ripening of juicy peach fruits and a using method of the plant growth regulator. The plant growth regulator for delaying ripening of the juicy peach fruits is characterized by being prepared from the components in parts by weight: 2-8 parts of gibberellins, 3-7 parts of daminozide, 1-5 parts of kinetin, 1-5 parts of maleic hydrazide, 10-16 parts of sodium naphthalene acetate, 4-9 parts of naphthylacetic acid, 1-6 parts of 6-benzylaminopurine, and 12-18 parts of compound sodium nitrophenolate. Through intervention of the adopted regulator, the ripening period of the juicy peach fruits is delayed, the unmarketable condition in the concentrated marketing season is avoided, and thus the economic benefits of fruit farmers are increased.

The invention relates to a method adopting hormones to promote flower bud differentiation of osmanthus fragrans. The method is characterized in that paclobutrazol of 500ppm is sprayed when spring twigs are substantially capped, paclobutrazol is sprayed once every 6 days and for three times in a term, paclobutrazol of 500ppm can be replaced with daminozide of 250ppm. The number of flower buds can be increased, the number of the flower buds sprayed with paclobutrazol can be 15.4-23.3% more than the conventional number, and the number of the flower buds sprayed with daminozide is 16.1-21.7% more than the conventional number. Based on study on endogenesis hormones and proportion variation of various hormones and the like in the process of flower bud differentiation and floral organogenesis of osmanthus fragrans, the method promotes flower bud differentiation of osmanthus fragrans according to variation of the endogenesis hormones and through application of exogenous hormones, increases the number of the flower buds and flowering times, prolongs an ornamental period, and improves integral ornamentation.

The invention relates to the technical field of flower cultivation, in particular to a method for cultivating peonies for oil. The method comprises the steps that sandy soil is laid in a greenhouse, pH is adjusted, and fertilization and sterilization are carried out; selected peony plants for the oil are planted with row spacing*line spacing of 30cm*50cm; hoeing and topdressing are carried out in the growing period of the peonies for the oil, indoor air ventilation and light transmission are kept, insect killing and sterilization are carried out, chlormequat chloride is sprayed, the flower head of each plant is covered with a plastic bag for 2-3 days, and then a plurality of small holes are pricked in each plastic bag with needles; in the florescence, the plastic bags on the flower heads of the plants are removed, gibberellins and daminozide are sprayed on pistils and stamens respectively, pollinating insects are placed in the greenhouse, temperature, illumination time and ventilation time in the greenhouse are controlled, and meanwhile hand pollination is carried out; fallen leaves are swept away in time, and are burned up or buried deeply in a centralized mode. According to the method, the growing conditions of the peonies for the oil are improved, meanwhile, the pollination success rate in the florescence of the peonies for the oil is increased, and therefore the seed setting rate is improved.
