Description

Technical Field

[0001] This invention belongs to the field of fertilizers, and specifically relates to a compound fertilizer for the cultivation of Camellia chrysantha. Background Technology

[0002] Golden camellia (scientific name: *Camellia nitidissima*), a plant belonging to the genus *Camellia* in the family Theaceae, is highly prized for its edible and medicinal uses. It contains a variety of nutrients and possesses unique and remarkable effects in lowering blood sugar, blood pressure, blood lipids, and cholesterol, as well as in managing diabetes and its complications, exhibiting a synergistic and balancing regulatory function.

[0003] With increasing market demand, research on the propagation and cultivation of golden camellia has emerged. Golden camellia prefers a moist growing environment and cannot be intercropped with other crops. Therefore, the cultivation requirements for golden camellia are relatively high, and the financial investment is far greater than for ordinary crops. To improve the yield and quality of golden camellia, it is essential to improve its fertilizer application. How to select different raw materials and simplify the preparation process to produce nutrient-rich and highly fertilizing fertilizers is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the shortcomings of the existing technology, a compound fertilizer specifically for Camellia chrysantha cultivation is provided. This compound fertilizer can ensure the soil's water and fertilizer retention capacity, effectively promoting the growth of Camellia chrysantha.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A compound fertilizer specifically for Camellia chrysantha cultivation, comprising the following raw materials in parts by weight:

[0007] 10-15 parts ammonium chloride, 6-10 parts potassium sulfate, 2-4 parts humate, 3-6 parts fruit shell powder, 2-5 parts polyglutamic acid, 2-5 parts chitosan, and 2-3 parts amino acid ester solution.

[0008] Preferably, the fulvic acid salt is one or a mixture of any of the sodium, calcium, magnesium, and ammonium salts of fulvic acid.

[0009] Preferably, the fruit shell powder is one of coconut shell powder, durian shell powder, walnut shell powder, and peanut shell powder.

[0010] Preferably, the nut shell powder can pass through an 80-100 mesh sieve.

[0011] Preferably, the amino ester solution is obtained by diluting 0.1-0.2g of amino ester with 15-16L of water.

[0012] This invention utilizes agricultural waste fruit shells, avoiding ecological damage and environmental pollution, and forming a virtuous ecological cycle. Polyglutamic acid provides excellent soil buffering capacity, reduces fertilizer nutrient loss, improves fertilizer utilization, and regulates plant growth, among other benefits. Chitosan is a natural plant growth promoter, acting as both a fertilizer and decomposing plant and animal residues and trace metals in the soil, converting them into plant nutrients, enhancing plant immunity, and promoting plant health. This invention also has water-retention properties, improving soil permeability, enhancing soil erosion resistance, and conserving fertilizer while increasing yield.

[0013] By combining the above-mentioned effective substances in the correct proportions, a fertilizer suitable for the growth of Camellia chrysantha was prepared. The fertilizer is rich in nutrients, has a simple preparation process, and possesses good economic prospects. Detailed Implementation

[0041] A 10-mu (approximately 1.65 acres) plot of land in a region of Nanning was selected and divided into five equal parts. Two-year-old seedlings of uniform height were planted in each part. Fertilizers prepared according to Examples 1-5 and Comparative Example 1 were applied to each part for a Camellia chrysantha planting experiment (commercially available Batian Shunshui compound fertilizer was used as a control group). The number of Camellia chrysantha plants and the amount of fertilizer applied were kept constant in each group (45 kg / mu). Conventional management methods were followed during the planting process, including regular watering and fertilization. After one year of cultivation, the growth of the Camellia chrysantha was monitored, and the specific results are shown in Table 1 below.

[0044] After applying the fertilizer formulated in this application, the growth of Camellia chrysantha is promoted. After one year of cultivation, the Camellia chrysantha plant can reach a height of 53 cm, and the total chlorophyll content reaches 1.9 mg / g, fully meeting the growth requirements of Camellia chrysantha. The addition of brown algae powder not only helps retain water, but the brown algae powder is also rich in minerals and small organic molecules, which can be directly or indirectly absorbed by Camellia chrysantha. Working in coordination with other components, it further promotes the growth of Camellia chrysantha.
