Description
Technical field
The invention belongs to washing salt technical field, more particularly to a kind of fruit-vegetable clear desalinization of soil by flooding or leaching and preparation method thereof.
Background technology
A large amount of pesticides are often used in the planting process of fruits and vegetables, are reducing the hair of insect-borne infectious disease and parasitic disease
Played a very important role in terms of raw, raising yield.A large amount of due to pesticide use, the pesticide residue of China fruits and vegetables
Excessive problem is increasingly severe.Some gourd, fruit and vegetables of in the market in planting process, due to pesticide it is excessive, or picking
Time is spaced too close together from spraying time, and substantial amounts of pesticide and its metabolin, degradation product have been remained on their surfaces and has been had
The materials such as malicious impurity, some have even invaded inside fruits and vegetables, have been not easy to be washed off by clear water.It is dirty by pesticide that if these are eaten for a long time in human body
The gourd, fruit and vegetable of dye, can cause harmful substance to gather in vivo, carry out potential threat to human body health care belt, or there is also food
Thing is poisoned, threat to life.Necessity of the fruit and vegetable as people's daily life, its safe importance are self-evident.
Research shows that pesticide residue is largely enriched in melon and fruit, vegetable surface, and pesticide is effectively removed by pruning outer micromicro
Residual, but can lose some nutritional ingredients of fruits and vegetables, and this method is only suitable for the fruits and vegetables that have pericarp etc, and can only go
Except the remains of pesticide of fruit and vegetable surfaces.The common pesticide residue method that removes of family is soaking and water washing method at present.Though soaking and water washing method
Removal water soluble pesticide can be so dissolved, but removal efficiency is not high, and this method is not suitable for being attached to fruit and vegetable surfaces yet
Fat-soluble pesticide, whole removing are poor except the pesticidal effects of fruit and vegetable surfaces.
The content of the invention
In view of this, it is provided by the invention it is an object of the invention to provide a kind of fruit-vegetable clear desalinization of soil by flooding or leaching and preparation method thereof
