Detailed introduction of plant growth regulators
Plant growth regulators are a class of substances that have similar physiological and biological effects as plant hormones. Plant growth regulators are a class of pesticides used to regulate plant growth and development, including synthetic compounds and natural plant hormones extracted from organisms.
Common classifications of plant growth regulators : common plant growth regulators include fast-acting amine ester (DA-6), chlorpyrifos, sodium nitrophenolate, brassinomycin , gibberellin ; prolonged storage of dormant amine esters ( DA-6), chlorpyrifos, sodium nitrophenolate, chlorophyll, sodium naphthalene acetate, methyl naphthalene acetate; breaking dormancy promotes germination of gibberellin, kinetin, amine fresh ester (DA-6), chloropyridyl Urea, sodium nitrophenolate, thiourea, chlorohydrin, hydrogen peroxide; promotion of stem and leaf growth gibberellin, amine fresh ester (DA-6), 6-benzylaminopurine, brassinolide, triacontanol Promote rooting of butyric acid, naphthaleneacetic acid, 2,4-D, long-lasting, paclobutrazol, ethephon, 6-benzylaminopurine; inhibiting the growth of stem and leaf buds, paclobutrazol, econazole, chlormequat, longer than Pixar, triiodobenzoic acid, fresh green pigment, rather embroidery powder; ethephon promote flower bud formation, daminozide, 6-benzylaminopurine, NAA, 2,4-D, chlormequat; inhibition of flower bud formation gibberellic Su, fosamine; thinning NAA, carbaryl, ethephon, gibberellin, indole cooked ester, 6-benzylaminopurine; protecting flowers and fruits 2 , 4-D, an amine hexanoate (DA-6), forchlorfenuron, sodium nitrophenolate, PCPA, gibberellin, 6-benzylaminopurine; extended flowering paclobutrazol, chlormequat, ethephon, than For a long time; induced the production of female flowers ethephon, naphthaleneacetic acid, indole acetic acid, chlormequat; induced gibberellin; cut flowers fresh ammonia oxyethyl vinyl glycine, ammonia oxy acetic acid, silver nitrate, silver thiosulfate; Seed fruit gibberellin, 2,4-D, anti-fallin, naphthaleneacetic acid, 6-benzylaminopurine; promote fruit ripening amine fresh ester (DA-6), chlorpyrifos, sodium nitrophenolate, ethephon, Longer than fruit; delayed fruit ripening 2,4-D, gibberellin, longer than, kinetin, naphthaleneacetic acid, 6-benzylaminopurine; anti-aging 6-benzylaminopurine, gibberellin, 2,4-D , kinetin; increase the amino acid content of paclobutrazol, anti-fallin, ripening ester; increase protein content of anti-fallin, simazine, atrazine, naphthalene acetic acid; increase sugar content of glyphosate, regulate phosphine, Pixar.
Promote fruit coloring of amino acid ester (DA-6), chlorpyrifos, sodium nitrophenolate, long-term, cooked ester, paclobutrazol ; increase fat content of naphthaleneacetic acid, chlorophyll, toxin ; improve stress-resistant abscisic acid, Paclobutrazol, longer than a short period of time.
The main points of use of plant growth regulators: the amount should be appropriate, can not be arbitrarily increased; can not be mixed at random; the method of use should be appropriate; growth regulator can not be used instead of fertilizer.

A Tape Measure or Measuring Tape is a flexible Ruler and used to measure distance.
It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. Today it is ubiquitous, even appearing in miniature form as a novelty item sb use tape measures in lengths of over100m.
There are two basic types of tape measures with cases, spring return pocket tape measures and long tape measures. Spring return pocket tape measures will generally fit in a pocket. They are small, the case is up to about three inches across. The tape is returned to the case by a spring mechanism. Pocket tape measures have a tape one foot to fifteen feet in length and ¼ to ¾ inches across. When most people think of a tape measure, they are thinking of the pocket tape measure.A second tape measure design is what is called the long tape. These are cased tape measures with tapes of 25, 50, 75, 100, 200, 300, and even 500 feet in length, designed for engineers and builders. Because surveying was usually done in rods, surveyors use long tapes of 33 feet (2 rods), and 66 feet (4 rods). Surveyors also used 49½ feet of a 50-foot tape for 3 rods and 99 feet of a 100-foot tape measure for 6 rods. Long tapes instead of being returned by a spring, were usually returned by hand crank.
