Brush Cutter, high branch chain saw, chain saw, lawn mower, the wind fire extinguisher, hedge trimmer is the most commonly used garden tools, as the manager of the golf course, the most troublesome thing Lawn Maintenance cost budget has increased year by year, turf quality not seen much improvement. The main reason is increased by the cost of fuel, equipment maintenance, water use and labor expenses caused; lawn defenders most of the time is spent in cutting mowing, watering and cleaning up grass clippings and fertilizer, disease prevention and pest control. Therefore, the stadium in order to save energy consumption, lower maintenance costs, try using some new technology, functional plant growth regulator is a good choice.

Concepts:

Functional plant growth regulator is a regulator of development and production for the plant to achieve a certain purpose, designed to dwarf lawn dwarfing agent, to promote turfgrass rooting dedicated rooting powder, lawn color, improve ornamental The colorant.

Role:

Functional plant growth regulator according to the nature of their role can be divided into two broad categories of growth promoters and growth retardants. The latter is divided into type I, type II two categories, I type can prevent the meristematic zone of cell division and differentiation, interrupt the biosynthesis of amino acids and fatty acids to inhibit turfgrass growth and development, and more for low-maintenance level or less pruning operation lawn. Such as plastic alcohol, maleic hydrazide. Type II block the extension and expansion of the meristem region, to inhibit the lawn growth by inhibiting the synthesis of gibberellin, less prone to the negative effects that can be used in the high level of conservation lawn. Such as fluoro sulfonyl grass amine is inhibition of cell elongation, paclobutrazol, uniconazole destroy plants gibberellin synthesis, slow cell growth.

Application:

Dwarf lawn, reduce the number of trim, reduce maintenance costs

In golf course maintenance budget, costs account for a large part caused by lawn mowers, situation sometimes lawnmower busy. Dwarf regulator lawn dwarf agents, can delay the growth of turfgrass, reduce the frequency of cutting swath, thereby reducing the wounds caused by the cut mow, reduce the incidence of disease and pesticides, fertilizer application rate, mowing the wear and tear of the equipment is also reduced. In addition, it will prevent thatch formation, increasing lawn appearance and texture.

With the growth regulators PRIMO, PROXY, S3307, fluoro-sulfonyl metolachlor and complex products, cool-season turfgrass dwarf lasted for about 40 days, a pesticide can reduce 7-8 pruning times. Biochemical function mainly through inhibition of gibberellin biosynthesis, cell growth inhibition of turfgrass section. Use foliar spray applicator. Soil applicator using a foliar spray, 2-3 days before and after the grass-cutting, re-spray, does not leak spray; sprinkle immediately after watering, allow the particles to settle to the root of the use of its stable, long-lasting release effect, to achieve the purpose of controlling plant height lasting.

To promote turfgrass Quick take root, and enhance resistance, reduce pests and diseases

Is to keep raising grass roots, the root good absorption we go, growing to do. Green super strength trimmed and kept at a very low growth state Department of lawn grass-roots developed, shallow roots, root activity, and resistance to harm reduction, vulnerable to pests and diseases and adverse environmental impact, I often see the whole greens disease swallowed. Well-developed root system, the lawn grass to absorb moisture, nutrients ability, comprehensive resistance is greatly increased, growing well.

Growth regulating agent having the function of 6-BA, KT, TA, NAA. Its role is characterized by activation of the root activity, and enhance the root activity of the enzyme induced lawn fast rooting; grow a lot of new roots after 7-12 days, compared biotypes rooting powder one month in advance, and root distribution of deep, thick root, root, root white; longest root of biotypes rooting powder 6.3 cm, the lawn drought significantly improve performance; New rooting, promote root effect is obvious; the lawn growing quick recovery, on the degradation, aging Lawn, by low-temperature damage lawns, pest serious harm lawn, ultrasound lawn, ball spot Lawn, the lawn rooting powder 10 days, the lawn growing rapid recovery, to maintain the natural, beautiful. Can enhance leaf photosynthesis, increase turf grass dry matter accumulation in the body, to improve their resistance to adverse environmental. This resistance effect on adult plants at the seedling stage is not obvious. Use foliar spray, cool-season grass with a concentration of 1200 to 1500 times with 800 to 1000 times, warm-season grass, planted a long time, the lawn of aging dosage should be increased.

Increased the lawn drought tolerance, increase drought, reduce lawn damage

Golf turf drought three principles: First, the use has prompted the lawn rooting function of plant growth regulators, in order to improve the root of the transverse and longitudinal exhibit the ability to expand the roots in the soil absorption area; dwarf lawn is to use a weakened Turf Growth potential growth regulators, weakening the growth potential of the lawn, to reduce the demand for water, improve plant drought resistance; Third, the use of anti-leaf transpiration function growth regulators, such as ABA, weakened turfgrass metabolism, reduce water loss, drought resistance is significantly enhanced. Using foliar spray generally use a concentration of 0.5 ppm to 1.0PPM, even spray 2-3 times, an interval of 5-7 days, the effect is obvious.

Increase the lawn color, enhanced ornamental, improve the utilization of the stadium

Due to frequent pruning, lawn grass disrupted Corn Plant Nutrient Distribution, reflected in the leaf surface is color or yellow, dry white, light green, or performance of growth and shrinkage, uneven, inconsistent color shades. In order to increase the color of the lawn, by the Green function of growth regulators is essential, especially for high traffic, high usage rate stadium, the use modifier by Green effect than any type of fertilizer faster, and some role is fundamental alternative fertilizer can not. With the growth regulator TA, acetic acid diethylamino ethyl ester (DA-6), nitrophenolate and sodium.

Improve lawn antifreeze capacity

Plant resistance to cold and their body's sugar content and soluble protein content, plant growth regulators in some extent, improve the cold resistance of the cool-season turfgrass. Related growth regulators the ABA, chitin, Trinexapac on, and can induce antifreeze factor, to activate the enzyme and increase the stability of the cell membrane; suppression and destruction of the the frozen protein into ice activity, increase the heat; or through the promotion of energy accumulation to improve their resistance to cold.

To break the grass seed dormancy, to promote rapid germination

Break dormancy growth regulators Triacontanol (TA), gibberellin (GA), KT, ethephon. It is characterized as break seed dormancy, shorten the period of dormancy, enhance the activity of the enzyme, to promote rapid germination of grass seed, improve the germination rate. Zoysia seed after GA treatment, a significant increase in germination rate. GA and cytokinin used in conjunction, can be lifted seed dormancy and promote a significant increase in the role of germination, while exogenous ethylene and ethephon (low concentration) is particularly evident on the lifting of the effect of seed dormancy. Adding a certain concentration of CO2 will significantly improve the application of ethephon, effect of ethephon breaking dormancy promote germination.

Difference:

We often use modifiers generally means that the product has some role, are general introduction, and are concentrated in the crops, the use of a certain lack of scientific index on the lawn. Such as CCC (CCC), whose role is to control vegetative growth, promote the growth of plant reproductive envoys shorter, stocky and lodging resistance, and promote leaf color deepened, photosynthesis strengthen all know. According to their role in the functional description, most people think of as well Retardant products on the lawn, but its specific use, what, how, and has no effect, research rarely the. Plus a lot of people understand the regulator from the agrochemical books, little is known about the advantages of complex products. Since With the function regulator products, making the regulator on the lawn swept off.

The functional role of regulator function loyal, research difficult, demanding the role function specific details to a variety of a plant. PRIMO used in planting more than 2 years of tall fescue 600PPM to 800PPM foliar spray, cut 3 days, 7 days showed significant dwarfing effect, duration of about 40 days. Functional regulator products developed complex type preparation, the ratio of science, expanded role and to avoid the use of a single preparation defects, complement each other so that each function, demonstrated a strong application. Such as the lawn rooting powder, both to stimulate rapid root rooting, dry matter accumulation, but also increase the body to improve the resistance of plants to avoid the use of a single product only rooting improve plant quality shortcomings.
