Problems solved by technology

In a word, from the point of view of the saline-alkali land improvement methods commonly used in China at present, there are mainly problems such as slow effect, high investment, generally 3-5 years to bear fruit, and difficulty in comprehensive promotion.
And in the prior art, there is not a scientific and effective comprehensive management method to improve the saline-alkali land, only take one of the small aspects of governance, the symptoms are not cured, and the saline-alkali land cannot be fundamentally improved

Embodiment 1

[0026] A method for improving saline-alkali land, for each mu of saline-alkali land, comprising the following steps:

[0027] ①Spread 500 kg of mushroom planting waste evenly on the soil surface, then plow 40 cm deep with a deep plowing machine, then irrigate and soak for 10 hours;

[0028] ② Drain the water in the saline-alkali soil, and then perform rotary tillage with a depth of more than 20 cm. Apply 50kg of organic farmyard manure, 5kg of amino acid fertilizer and 1kg of compound microbial bacterial agent at the same time as rotary tillage, and then plant seedlings after 3 days. Colonization; The composite microbial bacterial agent is composed of photosynthetic bacteria, Bacillus licheniformis, Lactobacillus acidophilus and Bacillus subtilis, wherein the photosynthetic bacteria, Bacillus licheniformis, Lactobacillus acidophilus and Bacillus subtilis in each gram of composite microbial bacterial agent The number of viable bacteria is greater than 3×10 8 , 5×10 8 , 4×10 ...

Embodiment 2

[0030] A method for improving saline-alkali land, for each mu of saline-alkali land, comprising the following steps:

[0031] ①Spread 550 kg of mushroom planting waste evenly on the soil surface, then plow 40 cm deep with a deep plowing machine, then irrigate and soak for 15 hours;

[0032] ② Drain the water in the saline-alkali land, and then perform rotary tillage with a depth of more than 20 cm. Apply 60kg of organic farmyard manure, 10kg of amino acid fertilizer and 2kg of compound microbial bacterial agent at the same time as the rotary tiller, and then plant seedlings after 3 days of cultivation. Colonization; The composite microbial bacterial agent is composed of photosynthetic bacteria, Bacillus licheniformis, Lactobacillus acidophilus and Bacillus subtilis, wherein the photosynthetic bacteria, Bacillus licheniformis, Lactobacillus acidophilus and Bacillus subtilis in each gram of composite microbial bacterial agent The number of viable bacteria is greater than 3×10 8...

Embodiment 3

[0034] A method for improving saline-alkali land, for each mu of saline-alkali land, comprising the following steps:

[0035] ①Scatter 520 kg of mushroom planting waste evenly on the soil surface, then plow 40 cm deep with a deep plowing machine, then irrigate and soak for 12 hours;

[0036] ② Drain the water in the saline-alkali land, and then perform rotary tillage with a depth of more than 20 cm. Apply 55kg of organic farmyard manure, 6kg of amino acid fertilizer and 1.5kg of compound microbial bacterial agent at the same time as rotary tillage, and then plant the soil after 3 days.

Abstract

The invention discloses an improving method for a saline-alkali land and belongs to the technical field of agriculture. For the saline-alkali land per mu, the method comprises the following steps: (1) uniformly spreading mushroom planting wastes on the surface of soil, after carrying out deep ploughing by using a deep ploughing machine, irrigating, and soaking the mushroom planting wastes for 10-15h; and (2) draining water in the saline-alkali land, carrying out rotary tillage, meanwhile, applying organic farm manure, an amino acid fertilizer and a composite microbial agent, and then, carrying out field planting on seedlings after 3 days since farmland fertility maintenance. The improving method for the saline-alkali land, disclosed by the invention, is used for improving the land under the condition of an original soil environment, wastes in the current mushroom planting process are adopted to form a breathable impermeable aggregate layer, saline and alkali are flushed to be clean by irrigation after the impermeable aggregate layer is mixed with a saline-alkali layer on a surface layer, and the impermeable aggregate layer can be used for effectively preventing planting oil on the surface layer from being salinized, so that a planting layer is suitable for plantation for a long term; and by using the method, flushing by using a great number of freshwater resources is not needed, so that the water consumption is effectively reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem, and the form is very serious. The area of ​​saline soil in the world is about 1 billion hectares, and my country has 99.13 million hectares, which is about 1.47 billion mu. More than 100 cities in the country are located in the saline-alkali distribution area . The saline-alkali land in my country is mainly concentrated in the arid and semi-arid areas of North China, Northwest and Northeast China. In addition, due to the long-term excessive application of chemical fertilizers during the cultivation process, the secondary salinization of the soil is intensified and the compaction is serious, so that the salinized and alkalized soil has been continuously expand. [0003] At present, domestic saline-alkali land improvement technologies can be summarized as follows...
