Embodiment 1

[0027] The saline-alkali soil improvement preparation is the product of Pinaceae plants. Specifically, the fresh leaves, fallen leaves or dead branches of Pinaceae plants are used to dry naturally, sun-dried or dried at 15-150°C, then crushed, and then subjected to 20-60 The purpose of sieving is to obtain the powder saline-alkali soil improvement preparation.

[0028] Or the improved preparation is to mix the extracts of Pinaceae plants with feces after fermenting, sterilizing and drying and crushing into feces powder with a particle size of 20-60 mesh;

[0029] The mixture mixed with feces is the mixture of pinaceae plant extracts and fermented, sterilized, dried and ground feces powder with a particle size of 20-60 mesh in a ratio of 1:1-5:1 in parts by weight.

[0030] Add 20-50 kg of feces powder to every 100 kg of pinaceae plant extracts and mix well to make a powder improver.

[0031] When in use, the powder prepared above can be uniformly mixed with the surface soil o...

Embodiment 2

[0033] Add every 100 kilograms of the powder improver obtained in the above examples into 100-500 kilograms of cooked soil powder, fully mix and evenly package. When used, it can be evenly mixed with the topsoil of the plow layer according to the amount of 100-400 kg per mu, or it can be directly sprinkled under the roots of plants or seeds and watered for irrigation. Can be reused as needed.

Embodiment 3

[0035] Mix every 100 kg of Pinaceae plant powder with 1000 kg of water, put it in a closed container, keep the temperature at 20-35°C and ferment for 5-20 days, fully homogenize and package, then it is a liquid saline-alkali soil improvement preparation. When in use, the liquid agent can be evenly sprayed or irrigated on the topsoil according to the dosage of 5-300L per mu. Can be reused as needed.

Abstract

The present invention relates to a soil improvement agent, and in particular relates to a saline alkali soil improvement preparation and a preparation method thereof. The improvement preparation is a Pinaceae plant product, a fermentation matter of a mixture of the Pinaceae plant product and water, or a mixture of the Pinaceae plant product and faeces, or a Kombucha fermentation cultivation product. The improvement preparation has significant effects on elimination of widely-existed salinization of the tillage soil, especially greenhouse soil and improvement of soil fertility and sustainable farming ability, and can also be used in repair improvement of saline alkali deserts and salinized cultivated lands.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a saline-alkali soil conditioner and a preparation method thereof. Background technique [0002] Salinization is a common secondary disaster that is difficult to overcome in modern irrigated agriculture. It often results in desertification of cultivated land and crop yield reduction or even failure. With the promotion and development of high-efficiency agriculture in greenhouses, the problems of soil degradation and secondary salinization in greenhouses are also increasing year by year, and the number of cultivated land that has been reduced or even unable to continue planting due to salinization is also increasing year by year. [0003] It is an effective way to improve salinized cultivated land by using saline-alkali soil conditioner. At present, there are a large number of saline-alkali soil improver products in the domestic and foreign markets, but most of these products have the disad...
