Ecological control method for preventing amphisarca root rot

Abstract

The invention discloses an ecological control method for preventing amphisarca root rot, which is characterized in that a farm land is ploughed according to the depth of roots of crops, deep-seated soil is externally ploughed and is dried by utilizing the heat of sunlight and the flow of air, and a certain amount of silty sand and humus soil are added to the ploughed soil; dry straws are flatly paved on the ploughed farm land and then ignited to sufficiently burn and uniformly distributed on the whole farm land; and furrow surfaces of high furrows and deep ditches are flattened. The invention solves the ecological control problem of amphisarca root rot prevention. The ecological control method uses the dry straws, the silty sand and the humus soil which all have low price, and the nutrient contained in the humus soil greatly reduces the using amount of fertilizer, thereby the invention sufficiently reduces the production cost, lowers the moist degree of the soil, retains the nutrient contained in the soil and also reduces the soil loss.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to the prevention and control technology of the roots of agricultural products and melons and fruits. The technology achieves the purpose of radically curing root rot through the scientific use of ecological control methods. Background technique [0002] Root rot is caused by fungi, nematodes, and bacteria. The roots of the damaged plants are rotten or even necrotic, and the diseased plants die. Fungi such as Pythium, Phytophthora, Rhizoctonia, Fusarium, and Sclerotinia are the main pathogens. The causative nematodes are mainly Brachybody nematodes. Bacteria that cause root rot are rare. The main root rot diseases are wheat take-all, beet root rot, bean root rot, asarum root rot and so on. The etiology is complex, often caused by 2 to 3 kinds of bacteria or 2 different types of pathogens. When the environmental conditions are suitable, the diseased plants are easily...

[0007] These methods mainly use pesticide preparations, which not only cost a lot of money and increase the burden on farmers, but also are extremely unfavorable to the soil structure and environment. At present, it is often because of excessive use of pesticide preparations, which not only increases the resistance of pathogens, but also causes the crops to suffer. Pollution is caused, which affects people's health and seriously affects the economic development of agriculture.
