Description
Technical field
The present invention relates to the identification methods that a kind of Chinese cabbage is endangered by soil secondary salinization, belong to modern agriculture field, can
For identifying Chinese cabbage planting site soil secondary salinization degree and Chinese cabbage by the extent of injury etc. of soil secondary salinization.
Background technique
In recent years, with the fast development of China's industrialized agriculture, the planting scale of facilities vegetable greenhouse constantly expands.Big face
Long-pending facility cultivation and long-time is recycled and derives many soil issues, such as soil hardening, soil secondary salinization, soil
Earth nutrient imbalance, soil acidification etc., wherein soil secondary salinization is particularly problematic.
Soil secondary salinization mainly due to unreasonable fertilising, irrigation method is improper, level of ground water increases, salinity increases
The reasons such as add, leads to nutrient salt ion (mainly NO3-、SO4-) largely accumulated in upper soll layer, so that soil salt content liter
Height so that causing soil the problems such as secondary salinization occurs, and then causes plant physiology obstacle, makes nitrate content in plant
A large amount of accumulation, this has not only influenced the normal growth and development of crop, more causes huge threat, such as vegetables to human health
Middle nitrate can be reduced into nitrite by human body intake, have the harm such as carcinogenic, teratogenesis.So be diagnosed to be vegetables whether by
Soil secondary salinization influence is of great significance.
Chinese cabbage is one of most universal vegetables in China, standby on the market to get consumer reception, Chinese north and south each province cultivation, especially
It is wide with the Yangtze river basin.Currently, planting Chinese cabbage in greenhouse, about 5-7 batches is produced per year, need application big with tempus intercalare during plantation
A large amount of applications of the chemical fertilizer of amount, chemical fertilizer cause overnutrition in soil, a large amount of accumulations of salinity in plant.Chinese cabbage is growing
In the process, higher salinity can be absorbed, edibility is by query, therefore scientific and reasonable identification Chinese cabbage is by Soil Secondary salt
The stain extent of injury has good guiding role for consumer.Also Wei You linked groups or individual propose complete set at present
And scientific and reasonable diagnostic process.
Summary of the invention
In order to determine Chinese cabbage by the soil secondary salinization extent of injury, the present invention provides a kind of Chinese cabbages by Soil Secondary salt
The determination method of stainization harm.The present invention passes through nitre in the content of eight- ions in judgement soil conductivity, soil and Chinese cabbage
Acid group content measures the degree that Chinese cabbage is endangered by soil secondary salinization, proposes the judgement side of complete set, reasonable
Method.
The object of the present invention is achieved like this, a kind of determination method that Chinese cabbage is endangered by soil secondary salinization, special
Sign is, comprising the following steps:
The acquisition of step (1), Chinese cabbage planting site soil, cabbages leaves；
Step (2), Chinese cabbage planting site soil whether by soil secondary salinization judgement；
The standard of perfection that step (3), Chinese cabbage are influenced by soil secondary salinization；
Nitrate anion limit standard in vegetables
| Vegetables classification | Nitrate anion/(mg/kg* fresh weight) |
| Solanaceous vegetables, melon, beans | ≤440 |
| Stem vegetables | ≤1200 |
| Root vegetables | ≤2500 |
| Leaf vegetables | ≤3000 |
In step (1), the region that entire greenhouse is several ten square metres is distinguished in standard planning, and every piece takes a little 5, each
Greenhouse takes acquisition soil sample 6 at random, corresponding 2 plants of random sampling that take soil point to carry out Chinese cabbage, take soil depth be 0-10cm,
The soil of 10-20cm, the soil acquired, cabbages leaves；
In step (2), the soil of acquisition is subjected to pedotheque measurement, soil secondary salinization is caused to obtain leading ion
NO-、SO4-、Ca2+It is measured containing measuring:
Ca in soil2+Measuring method are as follows: the measurement of NY-T 296-1995 soil total calcium, magnesium, sodium；
SO in soil4-Measuring method be；18 parts of NY T 1121.18-2006 Soil K+adsorption _ soil sulfate radical from
The measurement of sub- content；
The measuring method of NO3- is in soil；The measurement ultraviolet spectrophotometry of GB T 32737-2016 soil nitrate-N,
Nitrate radical content=(31/7) Content of Nitrate-Nitrogen in Soil in soil；
Criterion: standard is Second National overall survey of soil classification standard；Sentence if ion concentration is more than primary standard
It is set to soil and generates secondary salinization, carries out step (3)；
The criterion that step (3), Chinese cabbage are influenced by soil secondary salinization；
| Vegetables classification | Nitrate anion/(mg/kg* fresh weight) |
| Solanaceous vegetables, melon, beans | ≤440 |
| Stem vegetables | ≤1200 |
| Root vegetables | ≤2500 |
| Leaf vegetables | ≤3000 |
Chinese cabbage belongs to leaf vegetables: i.e. Chinese cabbage nitrate anion is greater than 3000, illustrates that nitrate anion is exceeded in Chinese cabbage body, Chinese cabbage is by soil
Earth secondary salinization influences.
The present invention by diagnosis soil conductivity, in soil pedotheque measurement cause soil secondary salinization obtain mainly from
Sub- NO-、SO4-、Ca2+The journey that Chinese cabbage is endangered by soil secondary salinization is measured containing nitrate radical content is measured in measurement and Chinese cabbage
Degree, proposes the determination method of complete set, reasonable.
