Problems solved by technology

[0005] Technical problem to be solved: the present invention aims at the current practical problems such as low seedling emergence rate of edible sunflower in moderate and severe saline-alkali land (arid and semi-arid areas), severe dead seedlings, weak root system activity, unbalanced soil nutrients, sticky texture, and soil compaction. , using the looseness and porosity of organic materials, the comprehensive nutrients of compound fertilizers, the anti-stress stimulation of growth regulators, and the activation performance of microorganisms, a saline-alkali land planting economy that improves soil, improves crop salt tolerance, and balances crop nutrient absorption is developed. Special fertilizers for crops and their preparation methods, and a set of specific applications for different soil salinity and texture conditions

Embodiment 1

[0038] Typical severe saline-alkali barrier cultivated land in Hetao irrigation area, Inner Mongolia. The soil salinity in the 0-20cm plow layer of the test plot is 6.6-7.8g / kg, the average salt content is 7.3g / kg, the pH is 8.47, the average organic matter content is 10.6g / kg, the total nitrogen is 0.78g / kg, and the alkaline nitrogen is 76.57 mg / kg, available phosphorus is 16.08mg / kg, available potassium is 149.1mg / kg, and the soil texture is clay loam. Location: Community 1, Chengni Village, Sandaoqiao Town, Hangjinhou Banner, Bayannur City, Inner Mongolia. It is a typical representative of saline-alkali land in the Hetao irrigation area. The test period was from June 2016 to September 2016. The experimental plot was an abandoned land in the early stage, and it was planted in 2015. It was a single-cooking sunflower variety, TY0904.

Embodiment 2

[0052] Typical moderate saline-alkali barrier cultivated land in Hetao irrigation area, Inner Mongolia. The soil salinity in the 0-20cm plow layer of the test plot is 3.1-3.7g / kg, the average salt content is 3.5g / kg, the pH is 8.56, the average organic matter content is 6.87g / kg, the total nitrogen is 0.40g / kg, and the alkaline nitrogen is 18.2 mg / kg, available phosphorus is 6.98mg / kg, available potassium is 271.1mg / kg, and the soil texture is sandy loam. Location: Community 4, Chengni Village, Sandaoqiao Town, Hangjinhou Banner, Bayannur City, Inner Mongolia. The trial period was from May 2016 to September 2016. In recent years, the sunflower variety TK9106 has been planted continuously. The main implementation links are as follows:

[0053] (1) Preparation of Bacillus subtilis spores: expand the Bacillus subtilis flora and inoculate it into the fermentation medium (0.5 parts of glucose, 1.0 parts of starch, 3.0 parts of soybean meal, 0.03 parts of dipotassium hydrogen phos...

Abstract

The invention discloses special fertilizer for commercial crops planted in saline and alkaline land as well as a preparation method and an application of the fertilizer. The fertilizer is prepared from peat soil, fulvic acid, compound fertilizer, bacillus subtilis spores, amino acid, a rooting agent, medium trace element fertilizer and attapulgite clay. The special improvement fertilizer which isused for planting of fresh sunflower and is prepared through proportion optimization of the materials and granulation with the attapulgite clay added to serve as a binder has multiple effects of providing special fertilizer effects, improving the soil quality, increasing the survival rate of beneficial bacteria, improving the resistance of crops, improving nutrient balance and the like after beingapplied to the saline and alkaline land. The special improvement fertilizer takes organic-inorganic compound fertilizer as the core, adsorbs concentrated bacillus subtilis spores, amino acid and plant growth regulator, granulation is performed through a disk granulating machine or an extruding granulating machine, and large-scale, mechanical and light popularization and application of the fertilizer are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and specifically relates to a special fertilizer for crops in saline-alkali land and its preparation method and application, in particular to a kind of fertilizer suitable for planting sunflowers in medium and severe saline-alkali areas in my country, which can provide nutrients and improve the salt resistance of crops Multifunctional special fertilizer for saline-alkali land, such as conditioning and improving soil, and its preparation method and application. Background technique [0002] my country has a total area of ​​more than 500 million mu of saline-alkali land resources, accounting for nearly 5% of the country's available land area. The area of ​​saline-alkali land with potential for transformation and agricultural development is 100 million mu, and more than 10 million mu are distributed in the saline-alkali area of ​​the upper and middle reaches of the Yellow River. The ...
