At present, it is the key period for the formation of kiwifruit quality. So, what management measures should the fruit farmers do to improve the quality and yield of kiwifruit? On August 12, the reporter interviewed Zhao Yingjie, senior agronomist, deputy director of the Eye Industry Center of Shaanxi Province. To this end, he made the following recommendations for the majority of fruit farmers: Disclaimer: Some articles on this website are transferred from the Internet.

Water management Because of the concentrated rainfall in autumn, the drainage of the park is extremely important. Fruit farmers should check the water accumulation at any time, dredge the ditch, and reduce damage to the root system due to water accumulation, high temperature and humidity. Especially in the early autumn, if the temperature reaches 35 °C or above, and the dry hot air produced by the dry climate often causes the leaves of the kiwi fruit to dry up and the fruit is burned, so in the high temperature and drought, watering and moisturizing should be carried out.
Pest Control After the fall, the main pests and diseases of kiwifruit are soft rot, gray mold, scorpion, leaf stalk, etc. If the control is not timely, it will not only cause defoliation, fruit drop, but also cause disease during harvesting and storage. Therefore, fruit farmers should promptly use the disease according to the occurrence of pests and diseases. According to the symptoms, the disease is controlled by a triazole fungicide, 80% methyl thiophanate WP 1000 times liquid, procymidone and the like. Insect pests can be controlled with 2,500 times of cyhalothrin or 1500 times of beta-cypermethrin, and the effect of alternate use is better.
In the orchard weeding, the rainfall in autumn is gradually increasing. The majority of fruit farmers should control the grass or weeds in the orchard, and weeding in time to increase the permeability of the orchard and reduce the humidity. At the same time, it is also conducive to reducing the occurrence of pests and diseases. The cut grass can be covered with a tree tray, which increases the organic matter of the orchard after rot, improves the soil aggregate structure, and enhances the soil's ability to retain fertilizer and water.
Key points of autumn management of kiwi orchard
The valve stem is an important part of the valve.
It is used to drive, connect the actuating mechanism or handle, and directly
drive the spool to move or rotate, so as to realize the function of valve switch
or regulation.Valve stem in the valve opening and closing process is not only
moving parts, stress components, but also seals. At the same time, it is
subjected to the impact and corrosion of the medium, and it also causes friction
with the packing. Therefore, in selecting the stem material, it must be
guaranteed that it has sufficient strength at the prescribed temperature, good
impact toughness, scratch resistance, corrosion resistance. The valve stem is a
vulnerable part, and the mechanical performance and heat treatment performance
of the material should be paid attention to when selecting.The valve stem in the
valve opening and closing process, under tension, compression and torsion force,
and direct contact with the media, as well as the relative motion between the
friction and filler, so in the choice of stem material, must ensure that it
provides adequate temperature strength, good impact toughness, abrasion
resistance and corrosion resistance of.
