Description

Technical Field

[0001] This invention belongs to the field of agricultural fertilizers, specifically relating to a boron-free and iron-free foliar fertilizer suitable for highland wolfberries and its preparation method. Technical Background

[0002] Goji berries are a traditional Chinese medicinal herb, rich in nutrients such as essential amino acids, vitamins, proteins, and numerous trace elements. The trace elements found in goji berries are shown in Table 1.

[0003] Table 1. Content of some trace elements in wolfberries

[0004]

[0005] Goji berries are a specialty resource of Ningxia. Due to the high economic benefits of goji berry cultivation, they have made a positive contribution to the local economic development. Goji berries also serve as a pioneer tree species for windbreak and sand fixation, and for improving saline-alkali land, offering significant ecological, economic, and social benefits, making them particularly suitable for cultivation in Northwest my country. In the late 1990s, Gansu and other regions widely introduced superior varieties of Ningxia goji berries, such as Ningqi No. 1, Ningqi No. 5, and Ningqi No. 7, leading to a gradual increase in the planting area of ​​goji berries in my country and the formation of a brand and cultivation model represented by Ningxia goji berries.

[0006] Goji berries are perennial plants, and their annual growth cycle does not clearly distinguish between vegetative and reproductive growth stages; the two overlap for most of the year. The application and absorption of both macronutrients and micronutrients are crucial for goji berry growth. The quantity of these two elements must be coordinated; otherwise, an excess or deficiency of either will affect yield.

[0007] The invention disclosed in authorization announcement number CN102249819B is a special organic-inorganic controlled-release fertilizer for wolfberry and its preparation method. The raw materials of the fertilizer are: an organic fertilizer-micronutrient composition, sulfur-coated urea with a high molecular weight polymer, 5% humic acid-coated urea, a urea base coating of 4% modified epoxy resin-coated potassium nitrate, diammonium phosphate, and granular potassium sulfate. The organic fertilizer-micronutrient composition is prepared by thoroughly mixing well-rotted organic fertilizer with boric acid and zinc sulfate at a mass ratio of 100:0.5-1:1-3 and then granulating according to existing technology. This special organic-inorganic controlled-release fertilizer for wolfberry is applied all at once before the wolfberry buds sprout in spring. This invention precisely combines fertilizers based on the nutrient absorption characteristics of wolfberry, ensuring that the nutrient release of the fertilizer matches the nutrient absorption of the wolfberry, effectively improving soil fertility and fertilizer utilization efficiency, and increasing the yield and quality of wolfberry.

[0008] Application No. 200510065339.0 discloses four types of compound fertilizers and four types of liquid micro-fertilizers specifically for wolfberry, along with corresponding fertilization techniques. Using urea, superphosphate, and potassium sulfate as raw materials, four concentrated compound fertilizers for wolfberry with completely different N, P, and K ratios for application at different stages of wolfberry growth and development, along with their application techniques, were invented. Additionally, using urea, KH₂PO₄, KCl, EDTA, CuSO₄, ZnSO₄, MnSO₄, FeSO₄, ammonium molybdate, methionine, sodium humate, sodium metasilicate, borax, sodium selenite, and rare earth nitrate as raw materials, four comprehensive and complete liquid micro-fertilizers with their application techniques were invented. Applying this invention results in larger wolfberries, increased 100-berry weight and length, and increased content of soluble solids, total sugar, protein, amino acids, and wolfberry polysaccharides, leading to a 10-15% increase in wolfberry yield.

[0009] Haixi Mongolian and Tibetan Autonomous Prefecture is a major goji berry producing area in Qinghai Province. Its geographical coordinates are 90°07′–99°46′ east longitude and 35°01′–39°19′ north latitude. It stretches approximately 837 kilometers east to west and 486 kilometers north to south, covering a total area of ​​325,800 square kilometers. The Qaidam Basin, the main part of the prefecture, covers 256,000 square kilometers, accounting for 85.28% of the prefecture's area. The prefecture's territory is primarily comprised of the Qaidam Basin, surrounded by the Kunlun Mountains, Altun Mountains, and Qilian Mountains. The basin's elevation ranges from 2,675 to 3,200 meters, while the surrounding mountains reach elevations of 3,500 to 4,500 meters. The terrain slopes from northwest to southeast. From its edge to its center, the basin exhibits five landform types: high mountains, hills, Gobi Desert, plains, and lakes / marshes, distributed in a ring-like pattern. It can be further divided into 3 major landform regions, 7 medium landform regions, and 23 minor landform regions. Based on their formation, landforms can be mainly classified into tectonic landforms, fluvial landforms, lacustrine landforms, glacial landforms, periglacial landforms, aeolian landforms, loess landforms, peneplains, karst landforms, and gravity landforms.

[0010] Currently, the goji berry planting technology and seedlings in Qinghai Province all originate from Zhongning County, Ningxia. Zhongning is located on the Weining Plain, an alluvial fan of the Yellow River, with an average altitude of 1225 meters, where goji berries can be harvested 8-11 times annually. In contrast, the areas in Haixi Prefecture suitable for goji berry cultivation have an altitude of 2675-3200 meters, and the climate, accumulated temperature, sunshine duration, soil quality, and agricultural activities such as goji berry planting and harvesting all differ from those in Zhongning County, Ningxia. Currently, there is no specific foliar fertilizer for goji berries tailored to the soil characteristics and environment of high-altitude regions. Summary of the Invention

[0011] This invention provides a foliar fertilizer specifically for highland wolfberry and its preparation method, addressing the lack of targeted foliar fertilizers for wolfberry cultivation in existing highland areas.

The slaughterhouse wastewater originates from the blood, scalding, rinsing, and rinsing processes at the slaughtering and necropsy sites, and includes animal blood, grease, meat scraps, bone fragments, animal hair, and feces. This wastewater has a high content of suspended organic matter. After pretreatment, it enters a biogas digester for degradation, forming biogas residue and biogas slurry. The biogas slurry is rich in amino acids and minerals. Because the biogas slurry from the high-altitude slaughterhouse contains animal blood components, it provides abundant amino acids and an organic iron source (non-free iron ions), which, in conjunction with a boron-free iron-free formula, significantly reduces fruit cracking rates.

[0034] Beneficial effects: This invention provides a foliar fertilizer specifically for highland wolfberries, tailored to the water and fertilizer characteristics of wolfberries grown in highland environments. It can effectively improve the yield and quality of wolfberries, reduce fruit cracking rate, increase disease resistance, and reduce the amount of fertilizer and pesticides used.
