Description
Technical field
The present invention relates to a kind of supplementary fruit tree zinc fertilizer and prevent and treat the method for little leaf disease, belong to agricultural technology field.
Background technology
Fruit tree little leaf disease is the physiological disease caused owing to lacking zinc element, main harm young sprout and blade, and young sprout internode is short at the initial stage of a disease, and top tip leaflet is grown thickly or baldness, and easily caducous, not easily Cheng Huanan bears fruit, and yields poorly or does not have.The organic substance that when fruit tree lacks zinc, photosynthesis is formed can not run well, and causes leaf chlorosis, growth retardation, affects output and fruit quality.It is general, especially obvious especially with saltings that sand ground, alkaline soil, barren ground and hillside orchard lack zinc.The method that present stage prevents and treats little leaf disease mainly contains several mode:
(1) soil application, namely ditches at fruit tree plant pit periphery or deep-cuts fertilising.Soil application needs a large amount of manpower to carry out ditching, applying fertilizer, and time-consumingly to take a lot of work and rate of fertilizer application is large, and investment is large; Root Absorption is slow, and weak effect, especially easily runs off at sand ground zinc element, and in alkaline soil, be easily converted into can not solvent for zinc, and the element that zinc is subject to phosphorus, potassium etc. in soil antagonism with it suppresses, and is unfavorable for that fruit tree Root Absorption utilizes.
(2) foliage fertilization, namely at fruit tree foliage-spray foliage fertilizer.Spray the effective way that foliage fertilizer is strong tree, disease-resistant, high yield, and method is simple, with fertile economical, successful, but because the human-subject test of peasant is not high, the foliage fertilizer of different concns can not be used according to zinc nutrition needed for fruit tree Different growth phases, fertilizer is caused not play one's part to the full, generally spray lower concentration foliage fertilizer, blade absorbed dose is limited, does not have good effect.
The method of existing control fruit tree little leaf disease has following defect: (1) little leaf disease sickness rate is higher; (2) efficiency is low, takes effect slow; (3) fruit tree leaves area is less, yields poorly, and commodity fruit rate is low; (4) with blindly fertile, there is fertilizer damage; (5) method is complicated, and cost is higher.
Summary of the invention
The present invention is directed to above deficiency, a kind of supplementary fruit tree zinc fertilizer be provided and prevent and treat the method for little leaf disease, realize following goal of the invention:
(1) sickness rate of fruit tree little leaf disease is reduced;
(2) efficiency of control fruit tree little leaf disease is improved;
(3) increase the leaf area of fruit tree, improve output of the fruit tree, improve commodity fruit rate;
(4) situation blindly using foliage fertilizer in traditional method is improved;
(5) fertilizer damage is reduced;
(6) simplify the operation, reduce costs.
For achieving the above object, by the following technical solutions:
A kind of control fruit tree little leaf disease efficient application method, is slowly grow or the dormant stage at fruit tree leafs such as fruit tree later rest in spring, blade ripening stage and senescence phases, sprays the high density foliage fertilizer of different ingredients, the generation of control fruit tree little leaf disease; It is characterized in that concrete steps are as follows:
(1) high density foliage fertilizer is sprayed later rest in spring
Before fruit tree dormancy in spring terminates the rudiment of tree body, spray the foliage fertilizer mixed solution that total concn is 3-6%, the chelated iron that formula is the urea of 1-4%, the chelated zinc of 1-4% or complexing zinc, 0.3-1.2% or Complexing Iron, 0.01-0.05% spreader-sticker, adjusting ph value with citric acid is 4.5-5, continuous spraying 1-2 time, interval is 7-10 days;
(2) first time in blade ripening stage sprays high density foliage fertilizer
Stop growing to before bud sprouts again at fruit tree leaf, spray the foliage fertilizer mixed solution that total concn is 0.5-2%, the chelated iron that formula is 0.3-1% urea, 0.5-1% chelated zinc or complexing zinc, 0.1-0.5% or Complexing Iron, 0.01-0.05% spreader-sticker, adjusting ph value with citric acid is 4.5-5, continuous spraying 1-2 time, interval is 7-10 days;
(3) the blade ripening stage sprays high density foliage fertilizer for the second time
Before again sprouting to bud after fruit tree second time young sprout stops length, spray the foliage fertilizer mixed solution that total concn is 0.5-2%, the chelated iron of 0.3-1% urea, 0.5-1% chelated zinc or complexing zinc, 0.1-0.5% or Complexing Iron, 0.01-0.05% spreader-sticker, adjusting ph value with citric acid is 4.5-5, continuous spraying 1-2 time, interval is 7-10 days;
(4) the leaf senile phase sprays high density foliage fertilizer
Before defoliation of fruit trees, spraying 4-8% foliage fertilizer mixed solution, fill a prescription as the chelated iron of 1-4% urea, 1-4% chelated zinc or complexing zinc, 0.4-2% or Complexing Iron, 0.01-0.05% spreader-sticker, is 4.5-5 by citric acid adjustment ph value, continuous spraying 2-3 time, interval time is 7-10 days.
Inner complex in foliage fertilizer in above steps, complex compound are mainly edetate, amino acid salts, Citrate trianion etc.
The spreader-sticker added in foliage fertilizer mixed solution in above steps, for Sodium dodecylbenzene sulfonate, modification gather trisiloxanes for the organosilicon agricultural surfactant that main component is composite and come, new high fat film pulvis etc.
Spreader-sticker can increase the area coverage of foliage fertilizer on blade, can improve the adhesive ability of foliage fertilizer on blade and resistance to erosion ability, prevent fertilizer from assembling in a large number at a certain position simultaneously.
The time spraying foliage fertilizer in above steps will avoid fine day and temperature higher time at noon, generally before fine day 10:00 in the morning and after afternoon 5:00 or the cloudy day; Spray at the mature leaf back side, young tender leaf face can not spray high concentration fertilizer.
Fruit tree is when rudiment, young leaflet tablet and a large amount of consumption of tissue store nutrition, and root system has just recovered receptivity, absorbs liquid manure indifferent, the nutrition needed for the growth of young sprout young tender leaf cannot be met, therefore spray the zinc element that foliage fertilizer supplements needed for fruit tree growth before rudiment very necessary.
Fruit tree young sprout stops long, after blade maturation, blade improves the tolerance of higher concentration foliage fertilizer, and now root system also enters slow vegetative period along with overground part stops progress, absorbing power declines, and now spraying foliage fertilizer can provide blade and its hetero-organization to regrow required zinc element.
