Description

A kind of special nutrient fluid preventing and treating peach tree yellow and preparation thereof and application
Technical field
The invention belongs to vegetable fertilizer manufacturing technology field, be specifically related to a kind of special nutrient fluid preventing and treating peach tree yellow and preparation thereof and application.
Background technology
Fructus Persicae cultivation extensively, is the third-largest deciduous fruit tree of China, and how delicious its fruit juice is, is the traditional fruit deeply liked by China people.According to FAO's data, 2013, China's Fructus Persicae cultivated area 11,660,000 mu, yield 11,950,000 tons, account for the 50.5% and 55.2% of world's total amount respectively.
Yellows are physiological disturbances important during China peach tree produces, it is possible to causing tree vigo(u)r weak, fruit diminishes, and causes that yield and quality declines, and even whole orchard has no harvest.In prior art, the single iron fertilizers such as the ferrous sulfate major measure as treatment peach tree yellow is used in the many employings of orchard worker, but effect is unsatisfactory.
Summary of the invention
It is an object of the invention to provide a kind of special nutrient fluid preventing and treating peach tree yellow and preparation thereof and application, the present invention holding time is up to 4-5, and can effectively prevent and treat peach tree yellow.
The technical solution used in the present invention is as follows:
Design a kind of special nutrient fluid preventing and treating peach tree yellow, the percent mass of described nutritional solution is composed as follows: carbamide 8-12%, potassium nitrate 4.5-5.5%, zinc sulfate 2-3%, magnesium chloride 1.8-2.2%, manganese sulfate 0.8-1.2%, copper sulfate 0.023-0.027%, boric acid 0.7-0.9%, potassium iodide 1.85-2.15%, sodium selenite 0.4-0.6%, cobaltous chloride 0.02-0.03%, aspartic acid 0.003-0.005%, mannitol 0.45-0.55%, ferrous sulfate 7-8%, citric acid 0.7-0.9%, calcium chloride 0.4-0.6%, potassium dihydrogen phosphate 0.2-0.3%, paclobutrazol 0.15-0.25%, surplus is distilled water.
Preferably, the percent mass of described nutritional solution is composed as follows: carbamide 10%, potassium nitrate 5%, zinc sulfate 2.5%, magnesium chloride 2%, manganese sulfate 1%, copper sulfate 0.025%, boric acid 0.8%, potassium iodide 2%, sodium selenite 0.5%, cobaltous chloride 0.025%, aspartic acid 0.004%, mannitol 0.5%, ferrous sulfate 7.5%, citric acid 0.80%, calcium chloride 0.5%, potassium dihydrogen phosphate 0.25%, paclobutrazol 0.20%, surplus is distilled water.
Research through inventor finds, adopts the reason that single iron fertilizer preparation is difficult to effectively treat peach tree yellows to be in that in prior art:
1) iron deficiency is not the unique inducement causing peach tree yellow, the disappearance of the elements such as magnesium, manganese, nitrogen, potassium, zinc, copper all can cause the malnutrition of peach tree self, cause that blade presents yellow symptom, and public cognition for peach tree this technical problem of yellowing leaf is exactly peach tree iron deficiency in prior art, therefore only supplements single iron fertilizer preparation and cannot effectively treat peach tree yellow symptom;
2) activation of ferrum element and assimilation effect are poor, although soil is required more wide in range by peach tree plantation, but in alkalescence or calacareous soil, iron ion carbonate easily and in soil is combined into the insoluble chemical compound of ferrum, and to the effective Fe of plant2+Easily it is oxidized to invalid Fe3+, thus causing that ferrum element is not easily absorbed by plants, therefore in most cases suffer from the root soil of yellows peach tree, the actual content of ferrum element is not low, but tree body is low to absorption and the Utilization ability of ferrum, causes that yellows symptom occurs in peach tree.
3) peach tree is when planting conditions is suitable, and growing way is excessively prosperous, especially the pumping excessive velocities of branch and blade, directly results in the mineral element that tree body absorbs and cannot meet its growth demand, and Chlorophyll synthesis amount is relatively low so that yellow leaf.
On this, three kinds of reasons directly result in and apply the problem that single iron fertilizer preparation cannot solve peach tree yellow so that the fruiting rate compared with normal peach tree of yellow peach tree is substantially reduced, and brings serious economic loss to orchard worker.
For above-mentioned three kinds of factors, applicant is through scientific research and testing for many years, by the adjustment to the component of nutritional solution and proportioning thereof, it is possible to effectively solving the symptom of peach tree yellow, principle is as follows:
1) demand rule according to nutrient each in the growth and development process of peach tree, nutritional solution not only adds iron fertilizer, also added peach tree and grow other mineral elements needed in especially leaf growth process, peach tree is carried out supplementing of full nutrition element, each element reasonable mixture ratio, nutrient is balanced, meets the growth demand of tree body and blade, make blade present normal green state, and maintain normal physiological function;
2) for solving ferrum problem of poor mobility in peach tree blade, nutritional solution with the addition of a certain amount of aspartic acid, after ferrum is combined with aspartic acid, cell interior can be entered by active transport pathways through cell membrane and play a role, namely be more conducive to activation and the operating of ferrum;
3) in nutritional solution, with the addition of paclobutrazol (having another name called PP333) component, the basis of General Promotion trunk infusion level can effectively control peach tree and nourished and grew prosperous, balanced nutrients and effect of regulation and control tree vigo(u)r golden mean of the Confucian school growth can be simultaneously worked as.
It is 4-5 that the present invention prepares the shelf-life of the nutritional solution of gained, harmless and be conducive to the marketization of nutritional solution to promote and implement to use.Like product safety of the prior art is poor, and majority in the dormant application of peach tree, can only be done prevention yellow and process, if but use at trophophase and do treatment yellow process, it is easy to cause that fallen leaves and shedding occur peach tree.Nutritional solution of the present invention does not then have the requirement of time of application, not only can prevent yellow in the dormant application of peach tree, and uses at the trophophase of peach tree and can treat yellow, without influence on the production of peach tree.
The preparation method of the special nutrient fluid of described preventing and treating peach tree yellow, step is as follows:
1) take each component by described quality proportioning, carbamide, potassium nitrate, zinc sulfate, magnesium chloride, manganese sulfate, copper sulfate, boric acid, potassium iodide, sodium selenite, cobaltous chloride, aspartic acid, mannitol are mixed and dissolves with distilled water, makes mixed liquor A;
2) ferrous sulfate and citric acid are mixed, dissolve with distilled water, make mixed liquid B, and mixed liquid B is slowly poured in mixed liquor A and is stirred continuously, make mixed liquor C;
3), after calcium chloride being dissolved with distilled water, slowly pour in mixed liquor C and be stirred continuously, making mixed liquor D;After potassium dihydrogen phosphate is dissolved with distilled water, slowly pour in mixed liquor D and be stirred continuously, making mixed liquor E;
4) by after paclobutrazol water dissolution, pour in mixed liquor E and be uniformly mixed, obtaining described nutritional solution.
The application of the special nutrient fluid of described preventing and treating peach tree yellow is in that, described nutritional solution carries out trunk injection and/or foliage-spray.
The step of trunk injection is: in the fruit expanding period of peach tree, described nutritional solution pure water is diluted 50-100 times, then the trunk base portion in peach tree is 45 degree of angularly lower borings, aperture 4-5mm, hole depth arrives xylem, then the nutritional solution of dilution 50-100 times is instiled in hole, instil after terminating with waddy blocking tree hole.
The step of foliage-spray is:
At peach tree trophophase, by described nutritional solution dilute with water 200-250 times, blade is uniformly sprayed 2-3 time, spray interval 7d every time.
The nutritional solution of the present invention directly acts on tree body and blade, root soil is not sprayed, it is prevented that ferrous ion is combined into the insoluble chemical compound of ferrum with the carbonate in soil, thus causing that ferrum element cannot be absorbed by tree body.
The present invention has actively useful technique effect:
1) nutritional solution of the present invention is formed by the various nutrient elements needed for peach tree growth promoter and phytohormone are reasonably combined, by improving tree body physiological metabolism, adjustment is nourished and grown situation, improve leaf quality and the anti-environment stress ability of peach tree, raising fruit quality and output results is obvious, can thoroughly cure the generation of peach tree yellows after using 2 years continuously;
