Embodiment 1

[0025] It is made from the following raw materials in parts by weight:

[0026] 80 parts of oyster mushroom residue, 30 parts of potassium humate, 30 parts of sulfur, 15 parts of soybean meal, 20 parts of scallop powder, 10 parts of clover powder, and 5 parts of ryegrass powder. After puffing oyster mushroom dregs, add soybean meal, safflower powder, clover powder, and ryegrass powder to adjust the pH and water content. After fully fermenting, add potassium humate and sulfur, and mix well to obtain the product.

[0027] Sprinkle on the soil surface before digging, and dig deep with the soil. The general application rate is 5000kg / hm 2 ~10000kg / hm 2 (dry weight).

Embodiment 2

[0029] It is made from the following raw materials in parts by weight:

[0030] 65 parts of oyster mushroom residue, 20 parts of potassium humate, 20 parts of sulfur, 10 parts of soybean meal, 20 parts of turnip powder, 10 parts of clover powder, and 10 parts of ryegrass powder. After puffing oyster mushroom dregs, add soybean meal, safflower powder, clover powder, and ryegrass powder to adjust the pH and water content. After fully fermenting, add potassium humate and sulfur, and mix well to obtain the product.

[0031] Sprinkle on the soil surface before digging, and dig deep with the soil. The general application rate is 5000kg / hm 2 ~10000kg / hm 2 (dry weight).

Embodiment 3

[0032] Embodiment 3: the cotton field effect test of the soil fertilizer improving agent for saline-alkali land

[0033] 1. The test site and the nature of the test soil:

[0034] Test location: Hekou District, Dongying City, Shandong Province.

[0035] Soil of the test site: moderate saline soil, light loam. The basic physical and chemical properties of the soil are: organic matter (0.95%), alkaline nitrogen (42.5mg kg -1 ), available phosphorus (19.4mg·kg -1 ), available potassium (179.6mg·kg -1 ), pH value 8.34, total salt content (0.31%), bulk density (1.92g / cm 3 ).

[0036] 2. Test time: from April 2011 to November 2013.

[0037] 3. Experimental design:

[0038] There are 3 treatments in the test, which are: (1) control: farmers' habits; (2) soil fertilizer improver 1: use the soil fertilizer improver prepared in Example 1; (3) soil fertilizer improver 2 : use the soil fertilizer improving agent that embodiment 2 makes. Application rate is 8000kg / hm 2 (dry weigh...

Abstract

The invention belongs to the technical field of agricultural production, and relates to a soil fertility improvement modifier, in particular to a soil fertility improvement modifier used for a saline-alkali land and produced by using waste fungi residues generated after oyster mushroom cultivation as main components. The soil fertility improvement modifier used for the saline-alkali land and produced through the cooperation of waste oyster mushroom residues as main components and salt-tolerant plant elements, and a preparation method of the soil fertility improvement modifier are provided by the invention; through the reutilization of the waste fungi residues, the recycling of agricultural waste resources can be realized, and the aims of resource circulation and soil sustainability are achieved; therefore, the favorable development of the circular agriculture and sustainable agriculture is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and specifically relates to a soil fertilizer improver, in particular to a soil fertilizer improver for saline-alkali land produced by using discarded fungus residue after cultivation of oyster mushrooms as the main component. Background technique [0002] As a special public resource product, cultivated land is closely related to the country's food security in quantity and quality, and is of great significance in maintaining national security and social stability. my country has implemented the most stringent arable land protection policy in the world, and it has become a national consensus to stick to the "red line" of 1.8 billion mu of arable land. Compared with the change of cultivated land quantity, the change of cultivated land quality is recessive, and the deterioration of cultivated land quality poses a serious threat to social and economic development and ecological envir...
