Abstract
The invention discloses a nutrient solution for preventing and treating chlorosis of a camphor tree. The nutrient solution comprises the following components in concentration by mass: 0.1-2 percent ofwater-soluble iron-contained compound, 0.01-0.1 percent of ethyoxyl modified polytrisiloxane and the balance of water. The invention also discloses a method for preventing and treating chlorosis of the camphor tree by the nutrient solution. The nutrient solution is applied to the camphor tree by a leaf surface spray method. The invention can effectively solve the phenomenon of the iron deficiencychlorosis of the camphor tree.
Description
Technical field
The invention belongs to plant cultivation technology, relate to a kind of at planting in the correcting method of the camphor tree iron deficiency yellows of the calcareous of pH＞7.0 or basic soil, and the nutrient solution of used control camphor tree yellows.
Background technology
Camphor tree claims fragrant camphor tree, wooden camphor tree, black camphor tree, fragrant camphor tree, kind camphor tree, fragrant stamen, camphorwood again, belongs to the Lauraceae aiphyllium.These seeds are thick with leaves, and hat is big shady dense, and the tree performance grandness can smoking lays the dust, water conservation, solid native sand prevention and beautify the environment, and is the fine tree species of urban afforestation, and Chang Zuowei shade tree, street tree, shelter forest and amenity forest are extensively planted.But the phenomenon of ubiquity blade in the camphor tree process of growth " chlorisis yellow " even whole plant death has seriously weakened peculiar advantage and the development of camphor tree as street tree and landscape tree.
The camphor tree yellows be a kind of mainly be the physiological disturbance that causes because of iron deficiency.The camphor tree yellow shows as the leaf look by green flavescence, attenuation, and there is the milky spot on the blade face, and vein is superfine green, and the leaf look pale when serious, the blade local necrosis, and the tender tip yellow of the lighter, weight person puts in order the strain yellow, and the tip of a branch is withered even complete stool is withered what is more.The main cause that camphor tree " iron chlorosis " is taken place is the soil meta-alkalescence, and the solubility ferrous iron becomes the ferric iron that plant is difficult to absorb in the soil.Iron is one of essential micronutrient element of plant, in plant corpus, bearing indispensable or effect, iron participate in chlorophyllous synthetic be again the composition of respiratory enzyme; Therefore, iron deficiency directly influences photosynthesis and respiration.Camphor tree is that low iron is coerced sensitive plant, and planting is easy to generate the iron chlorosis phenomenon in the limy soil or the meta-alkalescence soil of pH＞7, and especially as the street tree on construction of city afforestation and the major trunk roads, its planting-site point architecture rubbish and doline are many, soil CaCO
3Content is big, pH is high, so camphor tree iron chlorosis phenomenon is quite general even serious.For example, the iron chlorosis phenomenon generally appears in the trade camphor tree of husky economic development zone under the Hangzhou.
At present, though the sick control of camphor tree iron chlorosis method is numerous, but conclude get up mainly to comprise that iron fertilizer is manured into soil, trunk injection iron fertilizer and tree crown spray methods such as iron fertilizer, though these methods all have certain control efficiency, but effect is not ideal enough mostly, or it is not slow to take effect, or easy to operate or cost is big.For example, the soluble iron in the iron fertilizer very easily is converted into the ferric iron that plant is difficult to absorb after applying the limy soil of pH＞7 or basic soil, so its effect is often not ideal enough; Injection requires to select three or four on the thicker adult camphor tree major branch of the longer trunk of the age of tree, at each major branch base portion with the hand drill aperture that respectively to bore a diameter be 0.1cm, dark 6～8cm, in the cleaning hole behind the wood chip, in each aperture, inject some ferrous sulfate respectively and use bod, this method is troublesome poeration not only, and drill hole easy infection in the operating process; The foliage-spray method often adopts iron-bearing water solution such as ferrous sulfate, EDTA-iron, urea iron to carry out foliage-spray, though simple and convenient, the assimilation effect of iron ion is poor, and is also undesirable to the sick control of iron chlorosis.
The poly-trisiloxane surfactant of ethyoxyl modification is as a kind of organic silicon surfactant, and it is a kind of material that can reduce water surface tension significantly, is widely used as the pesticide spray auxiliary agent at present, and easily biological-degradable, and is environmentally safe.
At present, still do not use the ethyoxyl modification to gather the report of trisiloxane surfactant in the method preventing and treating of camphor tree iron chlorosis disease.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of nutrient solution of preventing and treating the camphor tree yellows, and the method for utilizing the control camphor tree yellows that this nutrient solution carries out, adopts the present invention can effectively solve the iron chlorosis phenomenon of camphor tree.
In order to solve the problems of the technologies described above, the invention provides a kind of nutrient solution of preventing and treating the camphor tree yellows, this nutrient solution is grouped into by the one-tenth of following mass concentration: 0.1%～2% water-soluble iron containing compounds, the poly-trisiloxanes of 0.01%～0.1% ethyoxyl modification, all the other are water.
Improvement as the nutrient solution of control of the present invention camphor tree yellows: this nutrient solution is grouped into by the one-tenth of following mass concentration: 0.15%～0.3% water-soluble iron containing compounds, the poly-trisiloxanes of 0.025%～0.035% ethyoxyl modification, all the other are water.
Further improvement as the nutrient solution of control of the present invention camphor tree yellows: water-soluble iron containing compounds is EDTA-iron, ferrous sulfate, urea iron or iron ammonium sulfate.
The present invention also provides the method for utilizing the control camphor tree yellows that above-mentioned nutrient solution carries out simultaneously: take the method for foliage-spray to apply nutrient solution to camphor tree.
The camphor tree blade face is moistening to get final product the consumption of nutrient solution to reach when the method for control of the present invention camphor tree yellows, each foliage-spray, so varying in size of camphor tree plant causes the difference of nutrient solution consumption.Sprayed 1 time every 10～15 days, multiple green fully until the camphor tree blade face.
The method of preventing and treating---foliage-spray method as present existing a kind of camphor tree iron chlorosis disease, the inventor finds that the reason of its result of use difference is: because the abundant cuticula in camphor leaf surface makes iron content nutrient solution (being the aqueous solution of water-soluble iron containing compounds) improve greatly at its surperficial tension force, thereby the iron content nutrient solution is difficult to sprawl on the blade face, thereby cause the assimilation effect of iron ion poor, the iron nutrient solution only infiltrates blade at part spot place, spray back yellow blade and usually have only a small amount of spot multiple green.
The present invention has added the poly-trisiloxane surfactant of ethyoxyl modification of certain proportioning in original iron-bearing water solution, thereby is mixed with a kind of nutrient solution of brand-new control camphor tree iron chlorosis disease; Foliage-spray method according to routine sprays nutrient solution of the present invention to the iron chlorosis camphor tree, can effectively reduce the surface tension of nutrient solution, reduces the contact angle on itself and blade face greatly, helps nutrient solution adhering to the blade face and to the leaf tissue internal penetration; Thereby effectively improve the absorption of camphor leaf, promote relevant physiological and biochemical procedure, finally make the blade of yellow progressively multiple green, thereby effectively cure the iron chlorosis disease of camphor tree ferro element.
