Problems solved by technology

The researchers added Na + , Si, N and P were used as fertilizers to study the coupling effect of these four mineral nutrients, and developed a sodium compound fertilizer that can enhance the drought resistance of succulent xerophytes (patent number: 2007100188400), which confirmed the degradation of sodium compound fertilizers in desert areas The ecological restoration of vegetation plays an important role. Although the development, application and promotion of the above-mentioned fertilizers have achieved certain results in the drought resistance of succulent plants, there are the following problems: ①Succulent plants have the adaptability of accumulating a large amount of N and repelling P characteristics, indicating that succulent plants have little absorption and utilization of P, and it is unreasonable to add a large amount of mineral element P in the fertilizer formula; ②The fertilizer lacks Ca 2+ , Mg 2+ and other important mineral elements, the effectiveness of fertilizers has not been maximized in terms of enhancing plant drought resistance or improving soil fertility

Embodiment 1

[0024] The desert succulent xerophyte mineral compound fertilizer of the present embodiment is made of the following components by weight: 20 parts of sodium chloride, 5 parts of ammonium nitrate, 20 parts of calcium chloride, 40 parts of magnesium chloride and 10 parts of sodium silicate .

[0025] The desert succulent xerophyte mineral compound fertilizer of the present embodiment is used for the hydroculture seedling of the desert succulent plant, and the test method is: the desert succulent xerophyte mineral compound fertilizer of the present embodiment is dissolved in the Hoagland nutrient solution, named It is a compound fertilizer nutrient solution, and in the compound fertilizer nutrient solution, the concentration of the desert sap xerophyte mineral compound fertilizer is 9.5g / L; the composition of the Hoagland nutrient solution is: 2mmol / LKNO 3 , 0.5mmol / LNH 4 h 2 PO 4 , 0.25mmol / LMgSO 4 ·7H 2 O, 0.1mmol / L Ca(NO 3 ) 2 4H 2 O, 0.5mmol / L ferric citrate, 92μmol / ...

Embodiment 2

[0044] The desert succulent xerophyte mineral compound fertilizer of the present embodiment is made of the following components by weight: 40 parts of sodium chloride, 10 parts of ammonium nitrate, 60 parts of calcium chloride, 10 parts of magnesium chloride and 7.5 parts of sodium silicate .

[0045] Test method is with embodiment 1, and 2 block groups in the present embodiment use respectively Hoagland nutrient solution (being the contrast 1 in embodiment 1), sodium compound fertilizer Hoagland nutrient solution (being the contrast 2 in embodiment 1) and compound fertilizer nutrient solution (processing 2), the concentration of desert succulent xerophyte mineral compound fertilizer in the compound fertilizer nutrient solution is 12.75g / L.

Embodiment 3

[0059] The desert succulent xerophyte mineral compound fertilizer of the present embodiment is made of the following components by weight: 20 parts of sodium chloride, 5 parts of ammonium nitrate, 20 parts of calcium chloride, 40 parts of magnesium chloride and 10 parts of sodium silicate .

[0060] The test method is: put the soil into a flower pot, measure the maximum field water holding capacity of the soil, when the soil water content is 70% of the maximum field water holding capacity, sow the germinated Overlord seeds evenly in the flower pot, and then cover with sandy soil , the thickness of the sandy soil is about 1.0cm. One week after Bawang emerges, water once every other week, and use a platform scale to monitor the change of soil water content every 3 days, so that the soil water content in the flower pot can be maintained at 70% of the field water capacity. About, carry out thinning treatment when plant height grows to about 10cm, make each pot keep 5 Bawang seedli...

Abstract

The invention provides a mineral compound fertilizer for desert succulent xerophytes. The mineral compound fertilizer comprises sodium chloride, ammonium nitrate, calcium chloride, magnesium chlorideand sodium silicate. The invention further provides application of the mineral compound fertilizer for the desert succulent xerophytes. The fertilizer application rate of the mineral compound fertilizer is 157.2-210.9 kilograms / mu when the mineral compound fertilizer is directly applied into soil in desert regions; a mass ratio of the mineral compound fertilizer for the desert succulent xerophytesto soil is (0.95-1.275 g):1 kg when the mineral compound fertilizer is applied to earth culture seedlings; the fertilizer application rate of the mineral compound fertilizer is 9.5-12.75 g / L when themineral compound fertilizer is applied to sand culture seedlings or water culture seedlings. The mineral compound fertilizer for the desert succulent xerophytes and the application have the advantages that the mineral compound fertilizer can be popularized and applied to the desert regions and can be used for culturing seedlings with strong drought resistance in the desert regions, accordingly, degraded desert vegetation can be rejuvenated and regenerated, growth of the degraded vegetation in the desert regions can be promoted, ecological environments can be protected and improved, and novelresearch prospects can be developed for ways for exploring the drought resistance of desert plants in arid desert regions; soil structures can be improved by the mineral compound fertilizer, the soilfertility can be enhanced by the mineral compound fertilizer, growth of the desert succulent xerophytes can be promoted by the mineral compound fertilizer, and the drought resistance of the desert succulent xerophytes can be improved by the mineral compound fertilizer.

Description

technical field [0001] The invention belongs to the technical field of mineral compound fertilizers, and in particular relates to a mineral compound fertilizer for desert succulent xerophytes and an application thereof. Background technique [0002] Drought is one of the most serious ecological and environmental problems faced by human beings. According to statistics, the world's arid and semi-arid areas account for one-third of the earth's land area, and my country's arid and semi-arid areas account for about 50% of the country's land area; especially in my country's northwest region, where the ecological environment is relatively fragile, due to extreme drought and little rain, The phenomenon of barren (sand) desertification is particularly serious, and it has become one of the countries with the most serious desertification problem in the world. Faced with the continuous degradation of natural ecosystems caused by drought on a global scale, scientists from all over the wo...
