Description

A kind of liquid fertilizer planting pear tree

Technical field

The present invention relates to cultivation of fruit tree planting technology field, be specifically related to a kind of liquid fertilizer planting pear tree.

Background technology

Pears, rich in abundant nutrition, are the hats of the big fruit in the world four.Pears Middle nutrition composition solubility is big, is easily inhaled by human body Receive, therefore have the title of " running water ", be conducive to dissolving element sulphur, make skin lubrication tender.Also rich in trace units such as potassium, magnesium, zinc in pears Element, is quite liked by people.Along with the development of society, along with improving constantly of people's living standard, the requirement to food is also got over Come the highest, but now in order to improve yield and the output value of pears, peasant household can apply a large amount of chemical fertilizer, but chemical fertilizer apply meeting in a large number Causing soil compaction, the physical arrangement of soil also can be destroyed, and causes its water conservation, fertilizer conservation, poor air permeability, if things go on like this, pears Quality is more and more lower；And plantation pear tree is usually plantation on level land now, on the downside of pear tree, leaves cannot be irradiated to sunlight, sun Light irradiates uneven, thus causes pears sugariness deficiency, the problem of quality reduction.

Summary of the invention

The technical problem to be solved is to overcome existing technological deficiency to provide a kind of liquid planting pear tree Fertilizer.

For solving above technical problem, the present invention provides following technical scheme: a kind of liquid fertilizer planting pear tree, fertilizer Making step as follows:
