Oyster mushroom residue organic fertilizer and application method thereof

Abstract

The invention discloses a preparation method of an oyster mushroom residue organic fertilizer. The oyster mushroom residue organic fertilizer comprises the following raw materials in percentage by weight: 60-80% of oyster mushroom residue and 20-40% of African marigold leaves. A preparation process of the oyster mushroom residue organic fertilizer comprises the following steps: drying the oyster mushroom residue, then crushing and passing the oyster mushroom residue through a 10-30mesh sieve; drying the African marigold leaves, then, crushing and passing the African marigold leaves through a 20-40mesh sieve; proportioning the sieved oyster mushroom residue and the sieved African marigold leaves in percentage by weight, and uniformly mixing to obtain the oyster mushroom residue organic fertilizer. The invention further discloses an application method of the oyster mushroom residue organic fertilizer. The oyster mushroom residue organic fertilizer disclosed by the invention can be used for effectively preventing and controlling root-knot nematode in soil and lowering harms of the root-knot nematode on plants, is high in fertilizer efficiency, particularly capable of promoting tomatoes to grow, low in production cost, simple in process, and capable of sufficiently utilizing industrial waste and agricultural waste of edible mushrooms to realize recycling of resources.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer of oyster mushroom chaff and an application method thereof. Background technique [0002] Root-knot nematode is the most widely distributed and most harmful plant parasitic nematode. So far, more than 80 kinds of root-knot nematodes have been reported, the most common ones are Meloidogyne incognita, M. arenaria, M. javanica and northern root-knot nematode. Knot nematode (M. hapla), among which root-knot nematode incognita is the most serious damage to crops. Root-knot nematode not only damages many economic crops such as soybean, peanut, citrus, banana, etc., but also damages a variety of vegetable crops such as cucumber, loofah, cowpea, kidney bean, eggplant, pepper, tomato and cruciferous vegetables. Diseases can cause crop yield reduction by 10-20%, and in severe cases, it can reach more than 75%. Root-knot nematodes mainly damage the roots...
