Embodiment Construction

[0008] 1. In the leisure high temperature season of the greenhouse, dig furrows every 120 centimeters, each with a width and depth of about 25 centimeters, and place the soil flat on both sides of the furrows, or plow to make 25×15 centimeters wide and deep furrows after rotary tillage , make this ditch according to the length of the greenhouse.

[0009] 2. Use plastic film to cover the furrows and the covering soil on both sides tightly, close the greenhouse film, and implement high-temperature greenhouse for half a month. Make the temperature in the greenhouse above 55°C, and the temperature inside the plastic film reach above 65°C. This high temperature can directly kill germs and root-knot nematodes in furrows and side soil. Thereby resulting in a good environment for planting crops, so that the repeated cropping diseases and insect pests are not infested.

[0010] 3. Remove the plastic film after the high-temperature stuffy shed, fill the ditch with organic manure, put ...

Abstract

The invention discloses a natural control method for continuous cropping diseases and root knot nematodes of greenhouse fruit and vegetables, and belongs to the technical field of vegetable gardening engineering of facility agriculture. Due to continuous cropping in a greenhouse, diseases and pests are accumulated, and the soil spreading damages take place generally so that output reduction or total crop failure even production stop is caused. According to the natural control method for the continuous cropping diseases and the root knot nematodes of the greenhouse fruit and vegetables, disclosed by the invention, natural cultivation and crop rotation are utilized; both of natural illumination and high temperature are organically combined to support the healthy energy and kill the diseases and pests so as to solve a problem of the diseases and pests and reduce the cost of chemical pesticide control and the pollution of chemical pesticides to natural environment; and the greenhouse fruit and vegetables can be continuously produced year by year.

Description

technical field [0001] The invention belongs to the field of facility agriculture and vegetable gardening. Background technique [0002] With the development of greenhouse vegetable production in facility agriculture, due to continuous cropping for many years, the organic matter in the soil has declined, and the accumulation of harmful pests and diseases has increased, such as root rot, creeping blight, sclerotia, wilt and root-knot nematodes, etc., resulting in reduced melon and vegetable production or dead. If spraying, fumigation, and watering are also difficult to achieve the desired effect with multiple chemical pesticides. And the cost is higher. And pollute the natural environment. The pests and diseases of heavy cropping are soil-borne diseases, which are relatively common in the production of melons and vegetables in greenhouses. It is also one of the current problems of agricultural soil-borne diseases and insect pests in the world. Contents of the invention ...
