The weather is hot and hard to tolerate vegetable management "three bogey"

One avoids excessive water control

Some vegetable farmers do not water for more than 20 days, so that high temperature and drought before and after noon, plant wilting phenomenon due to physiological water shortage, this is not conducive to the normal growth of vegetables, but also easily affected by soil drought Absorption of elements, such as the bacillus caused by calcium deficiency, can also cause viral diseases. It is recommended that vegetable growers adopt a watering method with a small amount of water to ensure the normal growth of vegetables. The time and number of watering can be determined according to the dry and wet conditions of the soil and weather conditions in the shed, and the fertilizer can be used once every other time.

Second bogey oversight

The peasants must be moderate when carrying out twigs and leaves, following the principle that the upper leaves of fruit are “not crowded” and the lower leaves of fruit are “small and fine”, and the photosynthetic leaves needed for normal fruit growth can be guaranteed, and the upper part of the fruit can be guaranteed. The leaves of the fruit can be shaded by the fruit, so as to avoid sunburn due to excessive light extraction caused by direct light extraction of the fruit, and to reduce the quality of the fruit.

Three bogey top outlet without pest network

Right now, pests like whiteflies and locusts that have migrated habits have begun to migrate into the shed, especially in the sheds of wheat fields, and are more vulnerable to pest infestation. A vegetable farmer is only accustomed to installing insect nets on the front face of the shed or on both sides of the arch shed, but no insect nets are installed in time at the top outlet to provide convenience for the invasion of pests. This situation is very conducive to the transmission of poisonous pests (such as powderè™±) Transmission of viral diseases may also result in the occurrence of coal pollution or fruit fleas (grass bites) as a result of large numbers of aphids and thrips, which reduces the yield and quality of vegetables. Therefore, it is necessary to set up an insect screen at the top outlet.
