Description
Technical field
The present invention relates to a kind of stagnant green dose of prolonging green period of lawn, be applicable to warm-season turf and cold-season type lawn, can realize that the lawn four seasons are evergreen, belong to the urban afforestation management domain.
Background technology
The four seasons are evergreen to be the basic demand of urban afforestation, still, divides other aspect to change because the four seasons, can appear to the reaction of climatic environment in the natural characteristic of plant.Concerning lawn plant, can be divided into warm-season turf and cold-season type lawn two big classes according to its area of origin with to the adaptability of environmental temperature, common warm-season turf has Bermuda, Korea lawn grass, centipede grass etc., its optimum growth temperature is about 25 ℃, acrial part stops growing when temperature is lower than 12 ℃, progresses into resting state, shows as the whole withered and yellow of ground cauline leaf, but the underground rhizome of its dormancy can be sprouted after the temperature rise again in the coming year, grew new lawn; Common cold-season type lawn has Festuca Arundinacea, meadow early hot standing grain, English ryegrass, the bent grass etc. of crawling, the evergreen lawn that promptly it has often been said, and its optimum growth temperature is 15-20 ℃.But under north of china in winter extreme low temperature or frost condition, the ground blade also can occur local withered and yellowly because of chilling injury, influences the view on lawn.
Shorten the lawn the withered and yellow phase, to prolong its green functional phase be the key that improves the annual comprehensive quality in urban afforestation lawn.The main cause that the lawn blade is withered and yellow is the disintegration and the chlorophyllous degraded of chloroplast in the blade, therefore, suppress the degraded of chlorophyll molecule in the blade, making it still can keep certain photosynthetic capacity under lower temperature is the major measure that prolongs the meadow green functional period.
Xia Ning etc. have invented a kind of fertilizer (CN00111171.X) that prolongs green period of lawn, mainly are made up of nitrogen-containing compound and iron containing compounds, are used for the foliage fertilization of turfgrass, also can be used for the plant that needs keep its green period of prolongation of blade physiologically active.This fertilizer mainly is the supply by increase nitrogen and iron nutritive element, promotes the growth potential of lawn plant, thereby reduces plant because the withered and yellow problems that malnutrition caused such as nitrogen stress and iron deficiencies.But the seasonal withered and yellow of lawn mainly is that the low temperature of autumn and winter season and frost can make the blade of cold-season type lawn occur damaging to plants caused by sudden drop in temperature, and cause withered and yellow because the environmental stress condition causes; And warm-season turf is for fear of the freeze injury in winter, and acrial part is all withered, tides over the adverse environment in winter with the form of underground dormancy stem.Too much nitrogen nutrition, though can keep plant growth potential preferably, its resistance to adverse circumstances such as low temperature can obviously descend, and may increase the lawn freeze injury.
The prolongation lawn is at the green period of autumn and winter, and key is to increase the resistance of lawn plant to low temperature, slows down the degradation speed of leaf chlorophyll, simultaneously, makes it can keep lower growing ability and the self-repairing capability to damaging to plants caused by sudden drop in temperature under lower temperature conditions.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of stagnant green dose of prolonging green period of lawn is provided, slow down the warm-season turf chlorophyll degradation speed in the temperature decline process in the fall, make it to keep the long green time; Increase the resistance of cold-season type lawn to low temperature, the lawn blade that the minimizing chilling injury causes is withered and yellow, realizes that the four seasons on lawn are evergreen.
To achieve these goals, stagnate green dose main component of lawn of the present invention comprises: suppress the elongation growth of lawn plant blade conditioning agent (the anti-ester that falls, Trinexapac-ethyl), reduce the water-loss reducer (cross-linked polyacrylamide) of moisture loss in soil and the plant corpus and nutritive element (nitrogen, potassium, magnesium) etc.Anti-ester is a plant growth regulators, can block GA in the plant corpus inner gibberellin route of synthesis
20To GA
1Conversion, thereby reach the purpose that suppresses plant excessive growth.This medicine is handled can significantly improve the resistivity of lawn blade cell to adverse circumstances such as low temperature, increases the content of leaf chlorophyll.Cross-linked polyacrylamide is the extremely strong water-loss reducer of a kind of water absorbing capacity, can effectively prevent the lawn leaf tissue after the use because dehydration that autumn, arid caused, avoids the lawn withered because of declining of causing of dehydration.An amount of nitrogen replenishes can keep the certain growth potential in lawn, and potash fertilizer nutrition can increase the anti-adversity ability of lawn plant, and magnesium is chlorophyllous necessary element, replenishes magnesium elements nutrition in right amount and can slow down chlorophyllous degradation process.Add an amount of surfactant in addition as auxiliary agent, with the absorption efficiency of raising lawn blade to stagnant green dose.
Lawn of the present invention stagnates green dose can make multiple formulations such as pulvis, suspending agent, specifically fill a prescription following (by weight percentage):
1) anti-ester: 0.25～1.25%
2) cross-linked polyacrylamide: 20～32%
3) urea: 20～45%
4) potassium dihydrogen phosphate: 20～40%
5) magnesium sulfate: 2.5～6%
6) surface-active auxiliary agent: 1～5%.Because the surface-active auxiliary component is to the stagnant green not directly effect in lawn, not the main contents of the stagnant green dose of invention in lawn, can select various surfactants such as polyoxyethylene, benzene sulfonic acid salt or amide-type commonly used on the market, the present invention does not limit the kind of surperficial coagent.
Lawn of the present invention stagnate green dose all applicable to warm-season turf and cold-season type lawn.During use, get stagnate green dose soluble in water, the green dose of ratio with water that stagnate is 1: 100-500, even spraying is on the lawn, stagnant green dose of usage amount on the lawn is 50-250 gram/mu.
Lawn of the present invention stagnates green dose and can slow down the warm-season turf chlorophyll degradation speed in the temperature decline process in the fall, make it to keep the long green time, can increase the resistance of cold-season type lawn to low temperature, the lawn blade that the minimizing chilling injury causes is withered and yellow, realizes that the four seasons on lawn are evergreen.
