As the manager of the golf course, the most troublesome thing is that the cost budget for lawn maintenance is increasing year by year, and the quality of the lawn has not seen much improvement. The main reason is caused by the increase in fuel costs, machine maintenance, water use, and labor expenditures; and lawn maintenance staff spend most of their time cutting grass, watering, cleaning grass and fertilizing, and preventing and controlling pests. Therefore, in order to save energy and reduce maintenance costs, each stadium has tried to use some new technologies. Functional plant growth regulators are a good choice.
concept
Functional plant growth regulators are regulators developed and produced for plants that achieve a certain purpose, such as dwarfing agents that are specially used for dwarfing lawns, special rooting agents that promote turfgrass rooting, and increased turf color and ornamental quality. The colorant.
effect
Functional plant growth regulators can be classified into growth promoters and growth retardants according to their properties. The latter is divided into two types: type I and type II. Type I can prevent cell division and differentiation in the meristem. It can inhibit the growth and development of turfgrass by interrupting the biosynthesis of amino acids and fatty acids. The lawn for trimming operations. Such as rectifying alcohol, suppress bud Dan. Type II prevents cell elongation and swelling in the meristem, inhibiting the synthesis of gibberellin to inhibit turfgrass growth, and is not prone to negative effects. It can be used in lawns with medium and high conservation levels. For example, fluorosulfonamide mainly inhibits cell elongation. Paclobutrazol and uniconazole impair the synthesis of gibberellin in plants and delay cell growth.
application
Dwarf the lawn to reduce the number of pruning and reduce maintenance costs
In the stadium conservation budget, the cost caused by grass cutting accounted for a large part, and sometimes the situation of cutting grass was too busy. If dwarfing regulators such as lawn dwarfing agent are used, the growth of turfgrass can be delayed and the frequency of cutting can be reduced, thereby reducing the wounds caused by cutting lice, reducing the occurrence of diseases, and the application amount of pesticides and fertilizers. The wear and tear of the implement is also reduced. In addition, it can also prevent the formation of a subtilis layer and increase the appearance and texture of the lawn.
The growth regulators with this function mainly include PRIMO, PROXY, S3307, flusulfoxan, and compounded products. The dwarfing duration of cool-season turfgrasses lasts for about 40 days, and once application can reduce 7 to 8 times. Prune times. Its biochemical function mainly inhibits the growth of turfgrass cells by inhibiting the biosynthesis of gibberellin. There are foliar spraying and application methods. If foliar spray is used, it is required to be used 2 to 3 days before and after cutting, no heavy spray, no leakage; if soil is used, water immediately after spreading, let the particles settle to the root, use its stable, long-term effect. The sustained release effect achieves the purpose of long-term control of plant height.
Promote rapid rooting of turfgrass, increase resistance, reduce pests and diseases
Raising grass is to cultivate roots. Roots must absorb well and grow well. Super green pruning of the greens and long-term maintenance in extremely low growth conditions, resulting in underdeveloped turfgrass roots, shallow roots, poor root activity, reduced tolerance to disease, susceptible to pests and diseases and adverse environmental impact, so often see the entire The greens were swallowed by the disease. Well-developed root systems absorb turfgrass, have strong nutrient capacity, and have a greatly increased overall resistance and growth potential.
The growth regulators with this function mainly include 6-BA, KT, TA, NAA and the like. Its role is to activate the root activity, enhance the activity of root enzymes, induce rapid rooting of the lawn, grow a large number of new roots 7 to 12 days after use, one month earlier than the biological rooting agent, and the deep root distribution, thick roots, roots, Root white: The longest root is 6.3cm longer than the biogenic rooting agent, which significantly improves the drought resistance of the turf; there are many new roots and obvious root-enhancing effects; the turfgrass recovers quickly, and the degraded and aging lawns suffer from low-temperature freezing damage to the lawn, causing serious damage to the pests and diseases. Lawn, over-frequency use of lawns, appearance of bulbous lawns, and use of lawn-specific rooting agents for 10 days, the turfgrass growth can be quickly restored to maintain a natural and beautiful appearance. At the same time, it can enhance photosynthesis in leaves, increase dry matter accumulation in turfgrass, and increase its resistance to adverse environments. This resistance has obvious effects on adult plants and is not obvious at the seedling stage. The method of application is mainly foliar spraying, the concentration of cold-season grass is 1200 to 1500 times, and that of warm-season grass is 800 to 1000 times. For the long-planting and aging lawns, the dosage should be increased.
Increase turf drought resistance, improve drought resistance and reduce lawn damage
The three principles of drought resistance of golf golf: The first is to use plant growth regulators that promote the rooting function of turf, in order to increase the horizontal and vertical deployment ability of roots, and to increase the absorption area of ​​roots in soil; the second is to use dwarfed lawns, weakening Growth regulators of turfgrass growth potential function, weaken the growth potential of the lawn, reduce the demand for water, improve the drought resistance of plants; Third, the use of growth regulators with anti-leaflet water transpiration, such as ABA, weaken the turfgrass metabolism, reduce Loss of moisture, drought resistance significantly increased. With foliar spray, the general use concentration is 0.5PPM to 1.0PPM, spray 2 to 3 times, interval 5 to 7 days, the effect is obvious.
Increase the color of the lawn, enhance the visibility, and improve the utilization of the stadium
Because turfgrass is frequently pruned, disrupting the distribution of nutrients in the plant body, the reflection on the leaf surface is the color difference or yellow, white, light green, or performance growth shrinkage, different heights, inconsistent color depth. In order to increase the color of the lawn, growth regulators with a greening function are indispensable, especially for stadiums with large passenger flow and high usage rates. The use of regulators to increase greening effect is faster than any type of fertilizer, and some functions are fundamental substitutes for fertilizers. Can't. The growth regulators with this function mainly include TA, diethylaminoethanol acetate (DA-6), sodium dinitrophenolate and the like.
Improve turf frost resistance
The cold-resistance of plants has a certain relationship with their sugar content and soluble protein content. Plant growth regulators can improve the cold resistance of cold-season turfgrass to some extent. The related growth regulators include ABA, chitin, trinexapac-ethyl, etc. They can induce antifreeze factors, activate biological enzymes, increase the stability of cell membranes, inhibit and destroy the ice-forming activity of frozen proteins, increase calories, or promote energy. Accumulation enhances its cold resistance.
Break grass dormancy, prompting rapid germination
The growth regulators that break the dormancy include triacontanol (TA), gibberellin (GA), KT, and ethephon. Its role is to break the seed dormancy, shorten the dormancy period, enhance the activity of the enzyme, promote the rapid germination of grass seeds, and increase the germination rate. Zoysia japonica seeds were treated with GA and the germination rate was significantly increased. The combination of GA and cytokinin can relieve the dormancy of seeds and promote the germination. The effect of exogenous ethylene and ethephon (low concentration) on the release of seed dormancy is especially obvious. In the application of ethephon, adding a certain concentration of CO2 will significantly increase the effect of ethephon breaking dormancy and promoting germination.
the difference
The regulators we often use generally mean that the product has certain functions, all are general introductions, and are mainly concentrated on crops. The use on lawns lacks a certain scientific index. Such as chlormequat (CCC), all know that its role is to control the vegetative growth of plants, promote plant reproductive growth, so that the internode shortened, dwarf and lodging resistance, promote the color of the leaves deepened, photosynthesis strengthened. According to its functional description, most people think that it can be used as a good dwarf product on the lawn, but the specific method of use, which varieties are effective, how effective after use, and whether there is any effect, etc. Now. Coupled with a lot of people understand the regulators are from agrochemical books, little understanding of the advantages of compound products. Since the use of functional conditioner products, the use of conditioners on lawns has swept away.
Functional regulators have specific functions and are difficult to research. They require specific functions and functions to be applied to a certain species of a plant. For example, PRIMO is used on tall fescue lawns planted for more than two years and sprayed with 600PPM to 800PPM. After 3 days of cutting, it can be used for dwarfing for 4 days. The duration is about 40 days. Functional conditioner products are mostly developed with compound preparations, with scientific ratios, which expands the function and avoids the use defects of single agents, making their respective functions complement each other and showing powerful application effects. For example, a special rooting agent for turf can not only stimulate the rapid rooting of roots, but also increase the accumulation of dry matter in the body and improve the resistance of plants, thus avoiding the disadvantage of using only rooting without improving the quality of a single product.
