Abstract
The invention discloses a leaf surface sprayed fertilizer for pear chlorosis. The fertilizer is obtained after urea, monopotassium phosphate, ferrous sulfate, magnesium sulfate, manganese sulfate, zinc sulfate and copper sulfate are mixed in a proportion. The leaf surface sprayed fertilizer provided by the invention is used for treating the pear chlorosis; after the fertilizer is sprayed to the pear garden with slight morbidity for one time, the pear garden can completely turn to green; after the fertilizer is sprayed to the pear garden with moderate morbidity for two to three times, the pear garden can completely turn to green, the leaves are thickened and the fruit growth is normal; the flower bud formation in the same year is boosted; and the sugar content of the fruit is increased to over 1.5%.
Description
Technical field
The invention belongs to fruit tree diseases prevention and treatment technical field, be specifically related to a kind of foliar applied fertilizer that is used for the pear tree yellow leat disease.
Background technology
Pear tree is a big fruit tree species of China, aspect two of cultivated area and ultimate productions, all accounts for first of the world.In recent years, pears output every year of China was all more than 9,000,000 tons, near 50% of world's pears ultimate production.Yet, in the pear tree of China produces.The cultivation level of various places is uneven, and the output and the mass discrepancy of fruit are very big, and yield per unit is from every mu of hundreds of kilogram to four five metric ton, and in the middle of this, the reason of existing pruning also has the reason of insect pest preventing and controlling, and reasons such as land occupation condition are also arranged simultaneously.Because the scope of China cultivation pear tree is very big, the land occupation condition of China is also very complicated, and cultivation is in the pear tree of sand loam soil, and general well-grown as long as supply with its required various nutritive elements, just can obtain satisfied fruit output and quality.But a big chunk pear tree of China is planted on the clayey soil that Soil structure is a viscosity, because pear tree flexibility is stronger, the pear tree of planting on the soil in this section is difficult to accomplish the thorough soil improvement work in orchard again.Because the air permeability of clayed soil is poor; A large amount of trace elements in the soil can not be converted into available state and absorbed by pear tree; Cause the nutritive props imbalance of fruit tree therefrom and the physiological disease of yellow leaf occurs; Because yellow leat disease makes that chlorophyll content reduces greatly in the blade, and then has had influence on fruit growth then, cause that fruit yield reduces, quality descends.Also had influence on bud then simultaneously and formed, the way of traditional treatment yellow leat disease is in soil, to apply ferrous sulfate, can play certain result of treatment, but because the soil root system disperses the less and expense material of taking a lot of work of fertilising scope, effect is not very good.
Summary of the invention
The object of the present invention is to provide a kind of foliar applied fertilizer of treating the pear tree yellow leat disease; This fertilizer recovers green demand to nutrition according to yellow leat disease takes place pear tree physiological reason and blade face; Will be big or middle, thereby micronutrient makes leaf green recover normal by the proper ratio compatibility; The blade thickening, the fruit normal growth promotes bud then to form.
For achieving the above object, the present invention takes following technical scheme:
A kind of weight ratio of each feed composition of pear tree yellow leat disease foliar nutrient is urea (18-22), potassium primary phosphate (32-34), ferrous sulfate (38-42), sal epsom (3-5), manganous sulfate (1-2), zinc sulfate (0.8-1.2), copper sulfate (0.2-0.4).。The weight ratio of active principle is nitrogen (19-23), phosphorus (17-18), potassium (21-23), iron (32-36), magnesium (1-2), manganese (1-2), zinc (0.8-1.2), copper (0.2-0.4) in the fertilizer.Each feed composition is mixed the fertilizer that can obtain required active principle.
Preferably, the weight ratio of choosing raw material is: urea (18-20), potassium primary phosphate (32-33.3), ferrous sulfate (38-40), sal epsom (3-4), manganous sulfate (1-1.7), zinc sulfate (0.8-1.0), copper sulfate (0.2-0.3).The weight ratio that can also preferably choose raw material is: urea (20-22), potassium primary phosphate (33.3-34), ferrous sulfate (40-42), sal epsom (4-5), manganous sulfate (10.7-2), zinc sulfate (1.0-1.2), copper sulfate (0.3-0.4).
Further preferred, the weight ratio of choosing raw material is: urea 20, potassium primary phosphate 33.3, ferrous sulfate 40.0, sal epsom 4.0, manganous sulfate 1.7, zinc sulfate 1.0, copper sulfate 0.3.
The content of active principle obtains through the fertilizer that configures is tested in the described fertilizer.
The present invention compared with prior art has following advantage:
1, nutrient content is complete, the nutrient reasonable ratio, and the pear tree that is fit to the sticking heavy theatre of soil is used the saving of labor to the nutrient demand characteristics, and fertilizer efficiency is fast, and utilization rate of fertilizer is high.
2, can make the pear tree blade change green comparatively rapidly, can significantly improve fruit yield and the fruit quality of pear tree.
3, according to prescription provided by the invention the pear tree that produces yellow leaf is used; The slight theatre of falling ill sprays once and can change green fully; The above theatre of morbidity moderate sprays two to three times can be changeed green fully, the blade thickening, and fruit growth is normal; Promote bud then to form, the sugar degree of fruit improves more than 1.5% than before using.
