The function of any greenhouse or greenhouse made of polycarbonate is to ensure the most favorable conditions for growing cultivated plants. At the same time, optimal temperature and humidity indicators contribute to the activation of various pests, microbes and pathogens. To prevent such phenomena, a special treatment of the polycarbonate greenhouse in the spring from pests should be performed, the results of which will be reflected in the form of an increase in yield and quality of fruits.
Pests and ways to deal with them
Polycarbonate greenhouses are infected with fungal diseases, spider mites and late blight. At the same time, for each pest or disease, a separate control method is provided. For example, with a spider mite, the method of fumigation or the use of sulfur checkers works effectively, however, in the case of fungi, this technique does not work. To prevent the development of late blight, soil should be actively dealt with, changing its composition, processing and fertilizing with copper. Integrated cultivation of the earth in a polycarbonate greenhouse in the spring will help to cope with other garden troubles, in the fight against which even specialized preparations are useless. Combining the disinfection of the greenhouse design and proper soil care, you can get a comprehensively effective program to combat any insects, diseases, and microorganisms.
Greenhouse cleaning
Before proceeding directly to the processing of the garden structure, it is necessary to prepare it accordingly. In addition, replacement of old twine and trellis may be required. The first step is to remove all the remains of vegetation from last season - these include the missing fruits, tops, weeds and roots.
It would seem that this material can be used for fertilizer in the future, but if it is planned to comprehensively treat the polycarbonate greenhouse in the spring from diseases and pests, then all plant residues will have to be burned. The fact is that pathogens appear not only in infected specimens, but also in healthy ones. After the winter period, they come to life and increase their activity. Nevertheless, under certain conditions, the remains of old plants can be used as compost. In particular, topping leaves is possible if:
- last season there were no outbreaks of disease;
- Compost is prepared for a minimum of 4 years (during this time the pests will die);
- fertilizer is not intended for the crop from which it will be made.
Preparing the design of the greenhouse for processing
At this stage, the goal is not to provide a disinfecting surface treatment, therefore it is enough to limit ourselves to the standard set for washing - water with soap and abrasive products. Polycarbonate is easy to clean with conventional cleaning products. Subsequently, the surfaces are easily washed with the applied chemistry. After that, a polycarbonate greenhouse can be treated in the spring from pests, which involves the use of more effective drugs.
In addition to the design of the greenhouse and, in particular, polycarbonate sheets, it is necessary to clean the inventory, racks, containers and containers. Plastic items are disinfected with bleach, boiling water, formalin or vitriol. In addition, disinfection of a polycarbonate greenhouse in the spring can be carried out using limescale. This product is also suitable for wood materials.
Greenhouse disinfection
Currently, gardeners use three main methods for processing polycarbonate greenhouses. Among them - slaked lime, sulfur drafts and biological products. Since there is a question about how to treat a greenhouse in the spring before planting, alternative methods of disinfection should be treated with caution, since the effect of many chemicals greatly affects the quality of the crop.
So, sulfur checkers can be used with the calculation of 50 g of substance per 1 m 3 of the greenhouse. This tool mainly affects insects and microorganisms, but is ineffective in the fight against late blight, bacteriosis and powdery mildew. Slaked lime is used to process elements of the greenhouse structure - it is diluted with copper sulfate and all surfaces of the frame, as well as the walls and ceiling, are disinfected with the resulting solution. Biological products in crop production are considered quite a promising direction. If there is a problem how to process the greenhouse in the spring before planting, then the preparations of this line will be the best solution. They eliminate fungal diseases and inhibit the growth of unwanted microflora in the future.
Greenhouse tillage
The peculiarity of soil exploitation in a greenhouse is due to the fact that it usually grows the same crop from year to year. This contributes to the conservation and development of harmful bacteria, which must be controlled by siderates, drugs with effective microorganisms and biofuels.
Thorough cultivation of the land in a polycarbonate greenhouse in the spring with the help of green manure will create optimal conditions for growing oats, mustard, facets, salads and other crops. Siderata are literally seeded to plants in the aisles, protecting them from all kinds of pests. Preparations with effective microorganisms also protect plants in the greenhouse from diseases and pests by colonizing the soil with beneficial bacteria. Special microorganisms multiply in the earth, improve its structure and have a healing effect.
Ridges on biofuels are also gaining popularity. This is an unconventional treatment of a polycarbonate greenhouse in the spring from pests, which also has the effect of warming. A wood filling is laid in the soil, consisting of old boards, hemp and other waste. In the future, this layer has a beneficial effect on plants in the greenhouse, and has a disinfecting effect.
Conclusion
To seasonal maintenance of the greenhouse gave the expected results, it is necessary to use several methods of disinfection and disarming of the surfaces of the structure and soil. Multilevel processing of a polycarbonate greenhouse in the spring from pests will help to cope with common microbes and insects. The main thing in this case is not to forget about protecting the plants themselves, which are sensitive to most potent drugs.
