Embodiment 1

[0016] Based on 100kg of ingredients: 15kg of desulfurization residue, 8kg of bentonite, 25kg of monoammonium phosphate, 27kg of urea, 21kg of potassium chloride or potassium sulfate, and 4kg of zinc sulfate.

[0017] wine grape test

[0018] Arrange experiments at the two test bases of Yuanlinchang and Yuquanying. The test adopts a comparative design, and there are 6 treatments in total, namely (1) blank treatment (no fertilization), (2) urea (40kg / mu), (4) saline-alkali soil fertilizer (80kg / mu), (4) saline-alkali soil fertilizer (95kg per mu), (5) saline-alkali soil fertilizer (65kg / mu), (6) special fertilizer (80kg / mu); each treatment was repeated three times, and the area of ​​the test plot was 20×3m 2 , the total area of ​​the test site is 1080m 2 . The amount of fertilization (calculated by mu) adopts an equidistant design, and the fertilization is divided into two times, and the ditch is divided into 30cm strips, and the water is irrigated in time after the applicat...

Embodiment 2

[0033] The compound fertilizer Lycium barbarum test prepared using the proportioning ratio of Example 1

[0034] The test is arranged in the two test bases of Yuanlinchang and Zhongning. The test adopts a comparative design, with 6 treatments in total, namely (1) blank treatment (no fertilization), (2) saline-alkali soil fertilizer (170kg / mu), (3) saline-alkali soil fertilizer (200kg / mu), (4) saline-alkali soil fertilizer ( 230kg / mu), (5) urea (40kg / mu), (6) special fertilizer (80kg / mu); each treatment is repeated three times, and the area of ​​the test plot is 10×3m 2 , the total area of ​​the test site is 540m 2 , The amount of fertilization (calculated by mu) adopts an equidistant design, and the fertilization is divided into three times, and the water is irrigated in time after the application. Except for different test fertilizers, other agronomic measures and field management were the same in each plot. Arrange 5 mu of demonstration fields in the adjacent fields of th...

Abstract

The invention relates to a saline alkali land improved special compound fertilizer for improving saline alkali lands and growing crops in the saline alkali lands, which is characterized in that the saline alkali land improved special compound fertilizer comprises 15 kilograms of devulcanized slag, 8 kilograms of bentonite, 25 kilograms of monoammonium phosphate, 27 kilograms of urea, 21 kilograms of potassium chloride or potassium sulfate and 4 kilograms of zinc sulfate as calculated by 100 kilograms of compositions; and the special compound fertilizer can provide organic nutritive compositions such as medium elements, microelements and humic acid, improve the quality of the crops, increase the reserve of soil nutrients, improve the effectiveness of nitrogen, phosphorus, potassium and the microelements, have important function on the balance of soil nutrient resources in the saline alkali lands, update and activate old organic substances, and improve the quality of humic substances, thereby comprehensively improving the soil fertility, the utilization rate of the nitrogen, and the activity of various enzymes such as invertase, protease and amylase in the soil, reducing ammonia nitration, promoting phosphorus absorption of the crops, reducing environmental pollution, contributing to environmental protection, and reducing the amount of the fertilizer, consequently saving the fertilization cost.

Description

technical field [0001] The invention relates to a saline-alkali improved special compound fertilizer for improving saline-alkali cultivated land and growing crops in saline-alkali cultivated land. Background technique [0002] (1) Shandong Province has developed a horticultural saline-alkali soil improvement fertilizer. This product is an organic-inorganic compound special fertilizer. Formulated with 16 ingredients. Contains 8-10% of nitrogen, phosphorus and potassium, pH5.5, uses the chemical reaction principle of acid-base neutralization, ion adsorption, and conversion of salts to reduce soil salinity, pH, improve various saline-alkali soils, and provide fertilizer with all nutrients The effect is obvious, and it can prevent the yellowing disease of flowers and trees. It is suitable for saline-alkali soil with a salt content below 0.4%, garden trees, flowers, lawns, potted flowers and fresh-cut flowers in protected areas.
