Example Embodiment
[0019] Example 1
[0020] Organic fertilizer is a mixture of 30% humus soil, 20% coffee shell, 20% bacteria bag, 20% plant ash, and 10% silkworm manure, and add Bacillus subtilis, actinomycetes, and Trichoderma (weight ratio 1:1:1). Bacteria liquid, the amount of the mixed bacterial liquid is 1% of the total weight of the organic fertilizer, and then fermented for 15-25 days under the conditions of temperature 65-70℃ and humidity 60-65% to obtain organic fertilizer; Organic fertilizer is 50%, and the same amount of biochar 50% is mixed, and after uniform mixing, fig fertilizer is obtained.

[0021] Example 2 Description of correlation experiment
[0022] experimental design
[0023] This experiment is a field experiment. The experiment site is located in Group 6 of Nuogutian Community, Tongdu Town, Dongchuan District, Kunming City, Yunnan Province, with an altitude of 1400.00 meters, an annual average temperature of 20.00°C, and an annual rainfall of 600.00 mm; the test materials are planted for ten years. Fig (Masiyi·Taofen), the experiment adopts the experimental design of random blocks. There are 3 blocks, 3 treatments and 9 blocks, each with an area of 222 m 2 , Respectively set the following processing:
[0024] ①Control treatment 1: No pruning, no fertilization, no top dressing, let the fruit trees grow freely.
[0025] ②Contrast treatment 2: first winter shearing, topdressing with biogas slurry 50kg / plant, 17-17-17 compound fertilizer 1kg / plant, and then applying urea 0.8kg / plant at the end of March. In the later stage of fruiting (late July), topdressing is don...

Abstract
The invention belongs to the field of fig planting, and particularly relates to a fertilizer for continuously maintaining high yield and stable yield of an old fig orchard. The fertilizer comprises anorganic fertilizer, beneficial bacteria and biochar, wherein the organic fertilizer comprises humus soil, coffee shells, fungus bags, plant ash and silkworm excrement, and the beneficial bacteria comprise bacillus subtilis, actinomycetes and trichoderma. The humus soil, the coffee shells, the fungus bags, the plant ash and the silkworm excrement are mixed according to a weight ratio of 3: 2: 2: 2: 1. The bacillus subtilis, the actinomycetes and the trichoderma are mixed according to a weight ratio of 1: 1: 1. The invention provides a method capable of continuously guaranteeing high yield andstable yield of the old fig orchard; with the method, the fig orchard after a high-yield period can continuously achieve high yield, and fruit quality is not reduced; and a certain improvement effecton the soil of the old orchard is achieved, which is of great significance to the old fig orchard.
Description
technical field [0001] The invention belongs to the field of fig planting, and in particular relates to a fertilizer for maintaining high and stable yields in old fig orchards. Background technique [0002] With the passage of time, the advancement of science and technology, the improvement of production and operation conditions, and the changes in market demand, fruit tree varieties, cultivation models and cultivation management techniques have been improved accordingly. The "new" orchards of that year also experienced a series of relative aging of production functions, which seriously affected The improvement of the overall efficiency of the industry has even become a restrictive factor for the sustainable development of the industry. In recent years, some orchard farmers still have the idea of emphasizing planting and despising management, and their management is extensive. After the orchard enters the full fruit period, the nutrient demand increases, but it has long re...
