Method for overcoming fruit tree replanting diseases based on microbial fertilizer

Abstract

The invention discloses a method for overcoming fruit tree replanting diseases based on a microbial fertilizer, which comprises the following steps: preparing the microbial fertilizer, digging a furrow in the middle of an original planting row according to the width of 0.8-1 m for a dug orchard, and separately placing surface soil and subsoil; during backfilling, filling surface soil in the bottom layer of the ditch, scattering Yihn wood composite microbial fertilizer on the surface soil, wherein the dosage of the Yihn wood composite microbial fertilizer is 4-5kg per plant, and then filling half of subsoil; and filling residual soil and the like into the fruit trees after being planted. The effect of the microbial fertilizer is detected, and physical, chemical and biological properties of soil are improved. Especially, the biological activity of the soil is remarkably improved, beneficial microorganisms, microfauna, earthworms and crustacean beneficial insects in the soil are obviously increased, decomposition and conversion of nutrients in the soil are promoted, absorption and utilization of crops are facilitated, and the yield increasing effect is obvious. After the old orchard is transformed and used, compared with a new land without orchards, the growth condition of newly planted young trees is high in survival rate of seedlings, normal in tree growth, early in fruit, high in yield and high in quality.

Description

technical field [0001] The invention belongs to the technical field of biological prevention and control of fruit tree diseases, and relates to a method for overcoming fruit tree replanting diseases based on microbial fertilizer. Background technique [0002] Woody fruit trees are perennial plants, such as apples, pears, peaches, apricots, citrus, persimmons, plums, etc., will suffer from serious replantation diseases, also called replantation obstacles. After the old trees in the old orchard are excavated, it needs to be fallow or rotated for 5-6 years before planting new seedlings, such as millet, corn, rape, soybeans, vegetables, etc. The economic benefits are extremely poor. According to statistics, by the end of 2015, my country's fruit tree area was about 1.1 million hectares, accounting for 20% of the world's fruit tree area, and its output was about 53 million tons, accounting for 15% of the world's total fruit tree production. Among them, at least 5% of the orchar...

Problems solved by technology

For example, a compound microbial fertilizer for preventing and treating cropping diseases has been proposed. The main component of this fertilizer is a mixture of compound microbial agent, inorganic fertilizer and peat. Because it contains a large amount of inorganic fertilizer, it is not suitable for the current organic and green fruit production, and the cost is high. Very high, little promotion value

There is also a Chinese patent that proposes "a fertilizer for preventing and treating crop replanting disorders (patent number: ZL200610003939.9)". The main component of this patent is medical stone, which is directly used as fertilizer by grinding and crushing, wherein SiO 2 、Al 2 o 3 , Fe 2 o 3 , MgO and other content as high as 42%, some studies believe that these elements can only be absorbed and utilized when they are above 300 degrees, that is to say, the utilization rate of large amounts of use is low, and long-term accumulation of elements will pollute the environment
