Problems solved by technology

[0002] Every year, 2 million hectares of irrigated land around the world suffer from saline-alkali invasion, and China's land resources are not optimistic. On the one hand, the development of urbanization will occupy a large amount of high-quality cultivated land. On the other hand, the intensification of soil erosion will cause the loss of nutrients in the soil. Unreasonable farming, extensive use of chemical fertilizers and pesticides, etc. cause soil degradation, and the result of soil degradation is to reduce the quality of crops, and even accumulate toxic elements, which seriously threaten the ecological environment and human health; Composition, including saline soil, alkaline soil and other types of soils that have undergone a certain degree of salinization or alkalization, among which saline soil refers to the soil that contains a large amount of soluble salts so that most plants cannot grow, and alkaline soil refers to the replacement Soils whose percentage of sodium ions accounted for more than 20% of the cation replacement capacity and whose pH value exceeds 8, in fact, because saline soil and alkaline soil are often alternately distributed, it is customary to collectively call them saline-alkali soil, and the development and utilization of saline-alkali soil can increase The area of ​​arable land can improve the ecological environment and form sustainable development; there are many ways to improve saline-alkali land, among which the use of saline-alkali soil improvers can effectively improve saline-alkali land in a short period of time, which is one of the better measures to improve saline-alkali land, but the existing saline-alkali soil improvers The effect is relatively single, and it is not good in improving the utilization rate of inorganic nutrients, which leads to the ineffective improvement of soil fertility and needs further improvement

Embodiment 1

[0015] 1) Firstly, 28 parts of milk vetch and 37 parts of peat are dried in the sun, and the sunshine time is 10 hours;

[0016] 2) Cut the milk vetch that has been dried in step 1), separate the stalk of the milk vetch from the root, then crush the stalk of the milk vetch to a length of 1 cm, put the peat into a high-temperature sterilization box for Sterilization, the sterilization time is 25min;

[0017] 3) After rinsing the root of milk vetch with water, dry it with filter paper, then soak the root of milk vetch with 75% ethanol solution for 1 min, rinse it with distilled water for 3 times after soaking, dry it with filter paper again, and then putting the root of milk vetch into a wall breaking machine for wall breaking and crushing, filtering out the liquid substance of the root of milk vetch after breaking, adding 0.2 parts of glucose to the filtrate, and set aside;

[0018] 4) Add the milk vetch stalks crushed in step 2), high-temperature sterilized peat, the preparat...

Embodiment 2

[0020] 1) First, 30 parts of milk vetch and 40 parts of peat are dried in the sun, and the sunshine time is 12 hours;

[0021] 2) Cut the milk vetch that has been dried in step 1), separate the stalk of the milk vetch from the root, then crush the stalk of the milk vetch to a length of 1 cm, put the peat into a high-temperature sterilization box for Sterilization, the sterilization time is 30min;

[0022] 3) After rinsing the root of milk vetch with water, dry it with filter paper, then soak the root of milk vetch with 75% ethanol solution for 2 minutes, rinse it with distilled water for 4 times after soaking, dry it with filter paper again, and then Put the root of milk vetch into the wall breaking machine to break the wall and pulverize it, filter out the liquid substance of the root of milk vetch after breaking the wall, add 0.3 parts of glucose to the filtrate, and set aside;

[0023] 4) Add milk vetch stalks crushed in step 2), high-temperature sterilized peat, preparati...

Embodiment 3

[0025] 1) Firstly, 32 parts of milk vetch and 43 parts of peat are air-dried, and the sunshine time is 14 hours;

[0026] 2) Cut the milk vetch that has been dried in step 1), separate the stalk of the milk vetch from the root, then crush the stalk of the milk vetch to a length of 2 cm, put the peat into a high-temperature sterilization box for Sterilization, the sterilization time is 35min;

[0027] 3) After rinsing the root of milk vetch with water, dry it with filter paper, then soak the root of milk vetch with 75% ethanol solution for 3 minutes, rinse it with distilled water for 5 times after soaking, dry it with filter paper again, and then Put the root of milk vetch into the wall breaker to break the wall and pulverize it. After breaking the wall, filter out the liquid substance of the root of milk vetch, add 0.4 part of glucose to the filtrate, and set aside;

Abstract

The invention discloses the technical field of saline-alkaline land improvement and specifically discloses a saline-alkaline land soil improvement agent which is prepared from the following raw materials in parts by weight: 43-55 parts of manure, 37-46 parts of peat, 28-34 parts of Chinese milk vetch, 22-30 parts of zeolite powder, 20-26 parts of ardealite, 10-18 parts of fulvic acid and 0.2-0.5 part of glucose, wherein the Chinese milk vetch belongs to leguminous plants, is one kind of good green manure; the root and stem of the Chinese milk vetch are separated, the stem part serving as greenmanure has basically the same functions as the manure; through decomposition of the stem part in soil, the content of organic matters, nitrogen, phosphorous, potassium, calcium, magnesium and trace elements is increased; the root of the Chinese milk vetch is fully sterilized and then subjected to wall breaking to obtain juice in the root; the juice contains a great quantity of nodule bacteria; adding glucose into the juice can enable quick reproduction of the nodule bacteria; the nodule bacteria has relatively strong nitrogen fixing effect, and when applied to the soil, and can reduce the loss of nitrogen in the soil and increase the utilization rate of nitrogen; moreover, the nodule bacteria can absorb nitrogen in the air so as to increase nitrogen in the soil.
