Problems solved by technology

However, currently the types of fertilizers used in tea tree planting are mostly NPK single chemical fertilizers or compound fertilizers, which are mainly composed of three inorganic elements N, P, and K; although they can meet the growth needs of tea trees in a short time, they will not Application will destroy the soil aggregate structure, which will easily cause soil compaction, soil hardening, decline in fertilizer and water retention performance, serious nutrient loss, environmental pollution and other adverse consequences, affecting the normal growth of tea trees, and subsequently affecting the biochemical quality of tea, sensory Significantly lower quality

preparation example Construction

[0028] The concrete steps of the preparation method of special ecological fertilizer for tea garden are as follows:

[0029] (1) The aerobic-underground high-temperature composting fermentation method is adopted, and the size of the composting tank is 4.0m×2.5m×1.0m in length×width×height. Ditches and ventilation pipes are set on the upper edge of the composting pool. Then take livestock and poultry manure, rapeseed cake, plant ash, potassium humate, mushroom slag, tea tree litter and biological bacteria preparations in proportion, mix them evenly, and pile them up for fermentation.

[0030] (2) In the early stage of composting, it is a heating stage, and the temperature rises from normal temperature to about 50°C. This stage generally lasts for 5-6 days. The second is the high temperature stage. The temperature in this stage is maintained at room temperature to 50-60°C. During this period, thermophilic cellulolytic bacteria decompose mainly, mainly decomposing complex substa...

Embodiment 1

[0035] Test location: An experimental tea garden in Dongzhi Fine Breed Farm, Anhui Province.

[0036] Test category: Fertilizer comparative test.

[0037] Fertilization method: After fertilization, use the tea garden tiller to rotate in time.

[0038] Picking method: mechanical picking.

[0039] Test process: set up three comparative treatment items, namely:

[0040] T1 treatment: use 15-15-15 conventional compound fertilizer as fertilization raw material, apply 150kg per mu per year, and the area is 1500㎡;

[0041] T2 treatment: use elemental fertilizers urea, superphosphate and potassium chloride as raw materials, and fertilize N and P annually 2 o 5 、K 2 The overall ratio of O is 4:1:1, with an area of ​​1000㎡;

[0042] T3 treatment: use the tea garden ecological fertilizer of the present invention as a raw material, and the area is 1200 square meters.

[0043] The fertilization period of the above-mentioned treatment items is the same, and the fertilization period i...

Embodiment 2

[0056] Test location: An experimental tea garden in Huizhou District, Huangshan, Anhui Province.

[0057] Test category: Fertilizer comparative test.

[0058] Picking method: hand picking.

[0059] Brief introduction to the test site: The soil of the test tea garden is yellow-red soil developed from phyllite and sand shale, with a pH value of about 4.30. Before the test in the tea garden, the tea tree growth, landscape and management level were average (approximately 22 kg of pure nitrogen per mu per year), and the yield was low.

[0060] Test process: In the test tea garden, set up a special ecological fertilizer test area (T) for tea gardens with an area of ​​1000㎡ and a local conventional fertilization control area (CK) with an area of ​​1000㎡.

[0061] The obtained test results are shown in Table 4 and Table 5:

Abstract

The invention belongs to the technical field of agricultural fertilizers and particularly relates to a special ecological fertilizer for a tea garden and a preparation method of the special ecological fertilizer. One of purposes of the invention is to provide the special ecological fertilizer. The special ecological fertilizer is prepared from urea, plant ash, potassium humate, ground phosphate rock, biomass charcoal, rape seed cake meal, livestock and poultry manure, a biological bacteria preparation, mushroom dreg and dry branches and fallen leaves of tea trees and has the advantages that the raw materials are easily available, the fertilizer is environment-friendly and energy-saving and contains balanced nutrients, the fertilizing amount can be substantially reduced, and the quality and yield of tea leaves can be improved. Another purpose of the invention is to provide the preparation method of the special ecological fertilizer for the tea garden. According to the preparation method, the special ecological fertilizer for the tea garden can be prepared by virtue of the most simple and convenient flow. The preparation method comprises the steps of preparing a primary material by virtue of an aerobic-underground high-temperature composting fermentation manner, and uniformly mixing the primary material with the urea, the ground phosphate rock and the biomass charcoal, so as to obtain the special ecological fertilizer for the tea garden.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a special ecological fertilizer for tea gardens and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of society, people have higher and higher requirements for the quality and safety of agricultural products and the agricultural ecological environment. Ecological tea gardens have become a hot spot in agricultural development in recent years. The ecological tea garden is mainly through the rational application of ecological fertilizers, thereby reducing the large-scale use of chemical fertilizers and pesticides in the tea garden, and achieving the effects of improving the soil environment of the tea garden, loosening the soil structure, increasing soil fertility, and improving the comprehensive soil fertility of the tea garden, thereby improving the quality of tea products and yield. Howe...
