Problems solved by technology

Although it has a certain effect on increasing production and income, long-term use will cause soil acidification and compaction, resulting in poor water retention, fertilizer retention, and air permeability of the soil, and less organic matter; secondly, it will cause excessive accumulation of harmful chemical residues in the soil. Being directly absorbed by plants has caused heavy metals in crops to seriously exceed the standard, affecting their growth and development
Due to poor air permeability after soil compaction, some fertilizers and pesticides are discharged into rivers and lakes or residual soil and crops, reducing the utilization rate of fertilizers, not only causing waste of resources, but also destroying the agricultural ecological environment and endangering the safety of humans and animals.

Embodiment 1

[0040] The management method of preventing and treating grape downy mildew of the present invention, concrete implementation method is as follows:

[0041] (1) Cut off the diseased shoots, branches and fruits of the grapes in autumn, clear the dead branches and leaves under the frame, and burn them in a centralized manner or bury them deeply;

[0042] (2) Timely pruning and binding new shoots in summer, improving the ventilation and light transmission conditions of the rack surface, timely cultivating and weeding, pruning reasonably, and removing vines and leaves on the ground;

[0043] (3) prepare the Bordeaux mixture of 1:0.5:100, and 200 times of liquid of 40% ethylphosphine aluminum wettable powder, and spray the foliage once every 28 days;

[0044] (4) Loosen the soil on both sides of the grape trellis, dig long trenches on both sides respectively, mix the new microbial organic fertilizer and the excavated soil with a weight ratio of 1:2, fill it in the trench, and then cov...

Abstract

The invention discloses a management method for preventing and treating grape downy mildew. According to the management method, novel microorganism organic fertilizers are applied, plasmopara viticola can be killed by virtue of antagonism of microorganisms, meanwhile multiple assistant measures are taken to treat both symptoms and root causes, and thus fruit trees suffering from diseases can be thoroughly cured. The management method disclosed by the invention is capable of reducing the amounts of chemical fertilizers and pesticides, plays an active role in protecting and utilizing soil and ambient agricultural environments, is capable of reducing the planting cost and increasing the economic benefits and the social benefits, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a management method for preventing and controlling grape downy mildew. Background technique [0002] Grape downy mildew is caused by the infection of Flagellate subphylum, Oomycetes, Peronomycetes, and Plasmopara. The fungus is an obligate parasite that only harms grapes. Under open field cultivation conditions, the fungus mainly survives the winter as oospores in fallen leaves. In warm winter regions, the mycelium attached to buds and leaves hanging on trees can also survive the winter. Its oospores can survive in the soil for about 2 years along with the rotting leaves. In the spring of the following year, when the temperature reaches 11°C, oospores germinate in small water droplets, produce germ tubes, and form sporangia. The sporangia germinate to produce zoospores, which spread to the green tissue of the host by wind and rain, and invade through stomata and water por...
