Problems solved by technology

Although these technologies play a positive role in improving salinized soil or improving crop yield and quality, some technologies have some limitations in application, such as underground pipe drainage can cause nutrient loss while removing soil salinity; guest-soil technology requires A lot of manpower and material resources are needed, and the symptoms are not cured; some harmful ingredients in the soil conditioner will be absorbed by the crops, which will cause adverse effects on the human body after consumption
At present, there are not many technologies and researches that comprehensively consider improving the desalination efficiency of salinized soil and reducing soil nutrient loss. There is an urgent need for a set of scientific control programs for facility salinized soil improvement, as well as the application methods and control conditions of the programs

Embodiment 1

[0021] For field control methods to improve facility salinized soil, see figure 1 , including the following steps:

[0022] (1) Applying soil structure conditioner: Dilute the soil structure conditioner at a ratio of 1 / 1600 and apply it to the soil at an application rate of 20kg / hm 2 .

[0023] (2) Apply soil water-retaining agent: Sprinkle MP3005KM soil water-retaining agent evenly on the soil surface of the plow layer after fully absorbing water, and the application rate is 22.5kg / hm 2 .

[0024] (3) Covering straw: Divide the dry rice straw into 2.5-8cm straw segments, spread them evenly in the field, and the covering amount is 4500kg / hm 2 .

[0025] (4) Application of EM active calcium solution: After straw mulching treatment, EM active calcium solution was evenly sprayed on the straw covering layer, and the volume ratio of EM calcium solution to straw mulching was 1:15. Among them, the preparation method of the EM active calcium solution is: weigh 28 grams of quickli...

Abstract

The invention provides a field regulating method for improving facility salinity soil. The method comprises the steps of applying soil structure conditioners and soil water-retaining agents on the surface of soil in sequence, mulching the soil with straw pieces to form a straw mulching layer, and spraying EM active calcium liquid onto the straw mulching layer finally. According to the method, regulation is conducted with the straw, the soil structure conditioners, the soil water-retaining agents, quick lime and effective microorganisms as main raw materials, facility cultivation salinity soil salinity is effectively reduced, and the content of organic matter, available nitrogen, phosphorus and potassium in surface soil is increased.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a field control method for improving facility salinization soil, which can effectively reduce the salinity of facility cultivation salinization soil and increase the content of organic matter and available nutrients in plow layer soil. Background technique [0002] China's protected cultivation technology has developed rapidly, and the cultivated area has accounted for 11.6% of the total agricultural production area. However, the problem of facility soil salinization has seriously restricted the sustainable development of facility agriculture, resulting in a large area of ​​facility soil yield reduction or even loss of production capacity. [0003] Aiming at the problem of soil salinization, domestic and foreign scholars have carried out many researches, including under-mulch drip irrigation technology, concealed pipe drainage technology, alien soil technology and soil cond...
