Description
Technical field
The present invention relates to domestication of plants field more particularly to a kind of organic preparation method of vegetable fertilizer and Nutrition Soils.
Background technique
Soil cultivation is still the cultural method of most crops at present, but soil long-time crop culture can be led
The fertility decline of soil is caused, the decline of soil fertility will lead to the reduction of crop yield, and bring to make up soil fertility
Yield reduce, people improve the fertility of soil further through chemical fertilizer is added to soil, and will lead to soil using chemical fertilizer for a long time
Earth is hardened, while crop seeds are sprouted there is no any usefulness using chemical fertilizer, and when excessive concentration results even in
It is that burn seedlings is dead that seed is sprouted shortly after.Hardened phenomenon, which once occurs, in soil will lead to the reduction of crops emergence rate, emergence speed
The problems such as degree is slow, and the speed of growth is slow after emergence, the phenomenon that in order to prevent soil hardening, people generally will use the excretion of animal
Object or the stalk of crops come as organic fertilizer using, but animal excrements limited source, and there are biggish for storage and transport process
Inconvenience, the stalk of crops needs to be utilized by crops after degrading, but the degradation of agricultural crop straw in the natural environment
Speed be it is very slow, it is lower to the facilitation effect of crop growth.

It should be noted that although fruits and vegetables residue is poured directly into soil also and facilitates plant and (be equal to farming in this case
Object) growth, but if fruits and vegetables residue is poured directly into soil, when first fruits and vegetables residue fermentative degradation needs longer
Between, be unfavorable for plant growth, second due to the nutrition content in fruits and vegetables residue be it is very high, can directly lead in the soil
The excessive concentration of nutriment in soil is caused, and excessively high nutrient concentrations are detrimental to plant germination growth in fact, sternly
The phenomenon that even will appear burn seedlings when weight, and after fermentation process, quite a few nutriment comes into fermentation liquid
(about 60% various nutriments can enter in fermentation liquid, and the nutrition content in filter residue is about 30% or so), paving
When being spread across on soil, the nutrient concentrations on soil have become to be particularly suitable for plant seed germination and grown.Simultaneously originally
Plant emergence in case is equal to the sprouting of vegetable seeds.
It needs to be emphasized that rotten fruits and vegetables are also considered fruits and vegetables residue after cutting off rotten position.
