Fertilizer for continuously maintaining high yield and stable yield of old fig orchard

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...

AI Technical Summary

Problems solved by technology

The fig tree species selected by this invention is a high-yield period in the local area of ​​3-5 years, and the annual yield per mu in the high-yield period can reach 3500-5500 tons / mu, and the economic life of figs is generally 30-50 years, so the planting area of ​​figs is constantly increasing. increase, followed by a series of problems, such as the aging of orchards, the decline in production quality, and low yields, etc.
