Description
Technical field
The invention belongs to fertilizer field, particularly a kind of fertilizer that prolongs green period of lawn and preparation method thereof.
Background technology
High speed development along with urban economy, living standards of the people improve constantly, requirement to living environment is more and more higher, the lawn area of residential quarter and urban afforestation constantly enlarges, China's lawn greening area reaches 1,500,000,000 square metres at present, a novel industry had been developed on the lawn already, as the important component part of urban afforestation, urban afforestation beautify with improvement of the ecological environment in bringing into play more and more important effect.Yet, because the development of China's Lawn Industry is started late, there is more problem at management aspect, the trend of " huge profit usefulness, undercuring " is very serious in the Lawn Industry development, has greatly influenced lawn life-span and quality.Wherein nutrient handling problem in lawn is distinct issues in these problems, and " reconstruction is planted, light nursing " is turf management Zhong Han problem to be solved.And, in the northern area of China, because weather is cold dry, lawn one is to winter, will become withered by green flavescence, even select the cold-season turfgrass that winter hardiness is strong, green period is long to come lawn planting, also have 3-4 month withered and yellow phase winter, greatly influenced the attractive in appearance and use value on lawn.
Turfgrass is the essentially consist and the functional unit on lawn, generally has the feature of close life, needs usually to cooperate to prune to keep surfacing.The turfgrass that uses all over the world has kind more than 100 at present, and these plants are chosen by the mankind, through cultivating the many kinds that form modern lawn plant.
The green of turfgrass is one of turfgrass most important characteristic, and good turfgrass answers the emerald green green homogeneous of branches and leaves and green phase long, and general good cold-season turfgrass green period is more than 200 days, and good warm-season turf green period is more than 250 days.It is withered and yellow that turfgrass becomes, and has a strong impact on the sight and the utility value on lawn, and then influence the urban green space view.
In the prior art, the technology that prolongs green period of lawn be turfgrass dormancy in the winter time withered and yellow after, on the lawn, spray the agent of enlarging afforested area, promptly be similar to the material of staining agent, artificially withered and yellow turfgrass is dyed green, the lawn a slice viridescent of looking far away, the time length can reach two months, and every square metre of cost is about 1 yuan.Still be in dormant state but dye green turfgrass, its color and luster is not the sort of plump green of the turfgrass of normal growth, can't carry out photosynthesis as the turfgrass of normal growth yet.Therefore, the decoration function that its green rose is also only as plastic flower, and both untrue, nature also can't play the due Ecology Action in lawn.

Principle of the present invention is: fertilizer of the present invention adopts the method for root outer spraying to impose on the turfgrass, utilize the physiologically active of nitrogen, iron, after the inhibition turfgrass enters autumn and winter, because low humidity, high light and other are coerced effect, leaf chlorophyll is decomposed to quicken, protein synthesis capacity reduces, and causes leaf chlorosis and the dormancy phenomenon occurs.By spray the fertilizer of prolongation green period of lawn of the present invention in good time, can delay the aging course of (or reverse) blade, the acceleration turfgrass is turned green spring, thereby prolongs the green period of turfgrass.
Component-the urea of nitrogenous substances among the present invention is a kind of neutral organic compound, and molecular volume is little, and degree of ionization is few, therefore, enters cell by cytolemma easily, helps blade it is absorbed.The urea that blade absorbs can be used for Nutrition and Metabolism, nucleic acid, VITAMIN, metabolic enzyme and chlorophyll etc. rapidly.Use urea autumn and can keep turfgrass blade vigor the long period.Iron is indispensable element to chlorophyllous formation, also is that (b, c, a) and many oxidasic important component parts play the electronics transfer function in photosynthesis, respiration process for ferredoxin in the plant materials, cytopigment.Therefore, not only influence photosynthesis during the plant iron deficiency, also suppress respiration, influence the formation of ATP, sucrose is synthetic to be reduced, and resists the ability drop of environment-stress.The inner complex of iron (as EDTA-Fe) can be absorbed rapidly by the turfgrass blade, impels the content of N, Fe in the cursive script to increase, and prolongs blade physiologically active then on the one hand, slow down the blade of grass that produces owing to dormancy move back green, the enhancing tolerance to cold; Quicken the recovery of turfgrass physiologically active in spring next year on the other hand, impel ahead of time and turn green, thereby reach the purpose that prolongs green period of lawn.Add plant growth retardent, can prevent the prosperous long phenomenon of turfgrass after executing nitrogen, increase the ornamental value of turfgrass.
Vitamins C (Vc) is an antioxidant the abundantest in the plant materials, external source applies when the Vc total amount increases in plant materials behind the Vc, it is more active that its biodegradation pathway also may become, except the increase of the content of Vc own can improve the anti-adversity ability of plant, the accumulation of the oxalate compound that produces by its degraded also can strengthen plant and resist low temperature that plant is subjected to, ozone etc. and coerce.The ferric iron that the while vitamins C can make plant be difficult to absorb is reduced into ferrous iron, improves the inner complex stability of iron and the effect that prolongs green period of lawn.
Execute Whitfield's ointment (SA) outward and can make SA content increase in the plant leaf, increasing amount and varietal resistance are proportionate, and the SA mechanism of action is: can give birth to heat effect by inducing plant, thereby make a kind of adaptation of plant generation to low temperature environment.Giving birth to thermal phenomenon comes down to relevant with the electron transfer system of cyanide-resistant respiration approach.Can improve the activity of plant nitrate reductase, the restraining effect of ABA of also flying up and down to plant-growth.Foliage spray SA can alleviate the active oxygen injury, and the protective membrane structure delays leaf senile, prolongs the green period of turfgrass.
The present invention compared with prior art, have following advantage and beneficial effect: the present invention is with nitrogenous compound, vitamins C, Whitfield's ointment and iron containing compounds or contain iron chelate and be used in combination, each component performance synergy has been brought into play the effect that prolongs green period of lawn well; Compound method is simple, and is easy to use; Foliage fertilization, consumption is little, and loss is few, and the effect that prolongs green period of lawn is remarkable.
