During the ripening of apricot fruits grown in greenhouses, fruit rots often occur, which reduces the economic benefits of greenhouse cultivation and should be monitored closely.
1. Apricot trees in spray booths should be cultivated in the same way as open fields. According to different phenophases, they can be sprayed in 80 to 100 times the sprouts, and 70% thiophanate-methyl 1000 after the flowers are sprayed. Times of fluid, fruit swelling period of 80% carbendazim 600 to 800 times the liquid, new shoot fast-growing period spray 65% ​​mancozebite 1000 times.
2. To improve the environment selection of high-quality non-drip film, timely removal of snow and dust on the surface of the film, to keep the film clean and increase the transparency of the film. In case of yin, rain and snow, 15 to 20 electric lights or biogas lamps are installed per acre shed to supplement the light and increase the temperature of the shed. In fine weather, it is necessary to pay attention to the timely release of air, to prevent the temperature, humidity is too high, so that the temperature of the greenhouse is kept below 28 °C, and the humidity is maintained at about 60%.
3. Keeping the fruit surface clean After the apricot tree is flushed with flowers, it is necessary to promptly remove the petals and other debris that are not attached to the fruit surface, and remove a part of the leaves that cover the fruit, so as to keep the fruit surface clean. Found that the disease was removed and buried in a timely manner.
4. Reasonable load In the year when there is a large amount of flowers and flowers, we should pay attention to thinning and thinning fruit, especially for some varieties with high flowering and fruit setting rate, such as golden sun, agate apricot, and so on. The standard of thinning and thinning fruit is that when the fruit is mature, the fruit and the fruit do not contact each other, and extrusion is appropriate.
Respiratory Protection
is a device designed to protect the wearer from inhaling particulate
matter, including airborne microorganisms, fumes, vapours and gases.
There are two main categories: the air-purifying respirator which forces
contaminated air through a filtering element, and the air-supplied
respirator in which an alternate supply of fresh air is delivered.
Within each category, different techniques are employed to reduce or
eliminate noxious airborne contaminants.
Respirators
range from relatively inexpensive single-use, disposable face masks to
more robust reusable models with replaceable cartridges.
They are also sometimes referred to as a dust mask or a gas mask.
