There are tricks for the management of zucchini
First, the picking period should be reasonable
As the plants continue to grow, the leaves gradually increase, which tends to cause depression in the field, poor ventilation and light transmission, and the lower leaves are difficult to see light for photosynthesis. On the contrary, because of the high humidity, it is easy to infect pathogenic bacteria and cause disease outbreaks. Especially in the deep winter season, the temperature in the shed is low, the humidity is high, and there are many pathogens. In addition, the lower leaves are easily broken and broken during spraying and picking melons, which is more likely to cause diseases. Therefore, it is very necessary for the zucchini to properly pick the leaves and improve the ventilation and light transmission.
The picking of the gourd should be based on the growth of the plant. If the growth is strong, the leaves should be picked more, and the weak ones should be picked less to ensure that the ventilation and light transmission in the field is good. In order to avoid the stalks are difficult to heal after injury, it is recommended that the vegetable farmers only go to the leaves without going to the handle. Because the petiole is thick and brittle, the leaves are removed from the base, and the stem is prone to large wounds, which are not easy to heal, and the leaves can be removed all or most, which can cause the petiole to dry out more quickly. In addition, it should be noted that it is best to have several consecutive sunny days when removing the leaves, so that the environment inside the shed is relatively dry and not susceptible to disease. After picking the leaves, the vegetable farmers can spray streptomycin 4000 times solution or Garonong 600 times solution to prevent disease infection in advance.
Second, Baohua Baogua is also very important
The difference in the time of smearing is too large, which tends to lead to an increase in curved melons and big heads. It is best for the vegetable farmer to smear the melon on the day before the flowering of the zucchini or 9-11 am on the flowering day. The squash is cultivated in the greenhouse, and the seedlings are mostly in the environment of short sunshine and low night temperature, which is conducive to the formation of female flowers. Generally, when the 3-4 true leaves are grown, the female flowers occur, and even the female flowers in the knuckles are more than one. female flower. Excessive female flowers are allowed to grow and develop, which inevitably consumes a large amount of organic nutrients. The competition of nutrients is fierce, affecting the growth of plants and young melons, and also causing a large amount of melons, which causes a serious decline in yield. Therefore, too many female flowers must be removed early to reduce nutritional competition and promote sitting. Excessive female flowers are best removed when they are revealed. The amount of female flowers to be removed should be determined according to the growth of the melons. Those who are weak and weak should first remove the root melon, and then leave a female flower every three or three days later; the melon can grow strong and leave the root melon, but it should be harvested early, and then leave a female flower every two or so. In accordance with the growth of melons and melons, we should adjust the amount of melons in time, minimize unnecessary nutrient consumption, maintain the healthy growth of melons, and achieve a melon.
Third, the late stage of the melon
In the late stage of melon, the plants are extremely tall, some even exceed 2 meters, which brings troubles to the management of picking and spraying. The growers should pay attention to the timely vines. The stalks can be buried with soil to promote the new roots and improve the roots. The ability to delay plant senescence and increase later yield.
