Embodiment 1~3

[0031] The preparation of embodiment 1~3 soil conditioner

[0032] The soil improver prepared in the following examples, after mixing different raw materials, adjust the water content to about 35% (w / w), put it into a plastic bucket with a cover and ferment in a closed manner, the fermentation temperature is 30-35 ° C, and the fermentation time is 30 ~60 days, when a large amount of white mycelium grows, it means that the fermentation is complete. The raw material components are as follows:

[0033]

Embodiment 4-6

[0035] The soil improver obtained in Examples 1-3 was selected for use, and tomato planting experiments were carried out in saline-alkali land along the Jiangsu coast.

[0036] Among them, the soil 1 is the saline-alkali soil of Dongtai Xinken tidal flat, Jiangsu Province, with a total salt content of 13.50 g / kg and a pH of 8.5.

[0037]Soil 2-4 is on the basis of soil 1, selects the soil improver among the embodiment 1-3 to carry out soil improvement, and concrete way is: select fine weather, soil improver according to 1: 60, 80 and 100 respectively The ratio is the same as that of the 0-20cm plow layer soil, fully mixed, let it stand for fermentation for 7-10 days, make ridges according to the spacing of 120, 180 and 200cm respectively, cultivate tomatoes on the ridges, and cover the weeds and crop straw with a thickness of 30-40cm between the ridges In the next year, the soil improver is fully mixed with the 0-20cm plow layer soil according to the ratio of 1:60, 80 and 100,...

Abstract

The invention discloses a soil conditioner. The soil conditioner is characterized by being prepared from beach saline-alkali soil, an EM decomposition agent and weeds which are fully and evenly mixed in the mass ratio of 1:(0.05-0.1):(0.1-0.15) and fermentation, wherein the beach saline-alkali soil is taken from soil 0-5 cm below the surface layer, the EM decomposition agent is a product obtained by fermenting an EM stock solution, crop straw and livestock and poultry excrement and has the C / N ratio between 20 and 25, and the weeds are sun-dried beach plants. The invention further provides an application of the soil conditioner in organic agriculture fertilizing for newly cultivated coastal beach saline-alkali soil. The soil conditioner contains multiple indigenous salt-tolerant microorganisms and can form dominant bacterial communities quickly after entering the soil to improve the microflora of the soil; brackish water is adopted in coastal irrigation, and the soil conditioner can maintain balance of the soil microflora in the crop planting period; the soil conditioner can increase effective nutrients, promote neutral leaching and salt discharge of the soil, improve the crop yield and quality and meet the organic agriculture planting requirement.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a soil improver and its application in organic farming and fertilization of saline-alkali land along coastal beaches. Background technique [0002] The total area of ​​salinized soil in my country is 9.91×10 7 hm 2 , different types of saline-alkali land are important real and potential agricultural resources in our country. In 2015, the "No. 1 Document" of the central government pointed out the "implementation of scientific and technological projects for high-yield grain and saline-alkali land improvement technology demonstration", indicating the importance and necessity of carrying out saline-alkali land management and improvement and efficient use of agriculture to ensure the supply of food, arable land, and agricultural products. Coastal tidal flats belong to coastal saline soil. Due to the short time for soil formation from saline silt to saline soil, coupled with th...
