Description
Technical field
The present invention relates to the soil detection technique, be specifically related to a kind of Apparatus and system that detects soil acidity or alkalinity.
Background technology
Soil acidity or alkalinity is claimed " soil reaction " again, and it is the acid-base reaction of the soil liquid, depends primarily on hydrionic concentration in the soil liquid, and with the pH value representation, at normal temperatures, it is neutral solution that the pH value equals 7 solution; The pH value is acid less than 7; The pH value is an alkalescence greater than 7.
The potential of hydrogen of soil will directly influence the growth of plant and conversion, release and the validity of soil nutrient.Generally speaking, under the situation of extreme acid, alkali environment, most of crops all are difficult to normal growth and obtain high yield.Soil aciditiy has certain relevance usually and between the validity of soil nutrient, is that 6 o'clock validity is the highest like soil phosphorus at pH, and when PH values was below or above 6, its validity obviously descended; The validity of nutrients such as ZINC IN SOIL, copper, manganese, iron, boron generally increases with the reduction of soil pH value, but molybdenum is then opposite.Some ion is too much and not enough in the soil, also can produce adverse influence to soil fertility.Like the not enough stability that can reduce soil agreegate of calcium ion, make it destructurized, the water permeability of soil thereby reduction; Aluminium, hydrogen ion are too much, soil are reacted acid and produce aluminium ion to poison; Sodion is too much, can make the soil react acid and produce the sodion murder by poisoning, all is unfavorable for the plant growth.So; The key factor that the too sour too alkali of soil all is restriction crop production and quality; Most the crop all not anti-too acid or the soil of alkali too; Therefore crop and the plant that adapts with soil acidity or alkalinity can be planted,, the strong clover of alkali resistant ability etc. can be planted such as much soil pH values are big in NORTHWEST CHINA, the north; And Southern Red Soil pH value is little, can plant the tea tree of happiness acid etc.
Soil acidity or alkalinity is very big to soil fertility and plant growth effect, and potential of hydrogen is many-sided to the influence of plant, be divided into substantially to external environment influence with plant self is influenced; For confirming wherein principal element; Through over thousands of grain wheat seed is divided into PH=4,4.5,5,5.5,6,6.3,7,7.5,9 gradients of 8 are carried out breeding, every regional about 100, cultivate with nutrient solution; After observing record through more than 40 days, its breeding data are as shown in the table:
| Potential of hydrogen | October 15 | October 18 | October 22 | October 25 | October 30 | November 2 | November 7 |
| 4 | 1.5 | 6 | 8 | 15 | 17 | ?19 | ?26 |
