Management Measures of Squash Squash

1, pick leaves. With the continuous growth of the plants, the leaves gradually increase, which tends to cause field canopy closure, poor ventilation and light transmission, high humidity, and easy infestation of pathogenic bacteria, leading to disease outbreaks. Therefore, it is very necessary for the squash to pick up the leaves reasonably. The leaves of the gourd should be determined according to the growth of the plants, and the harvested leaves can be picked more, while the weak ones should be picked less, so as to ensure good ventilation and light transmission in the field. In order to avoid the stalks from being hard to heal after injury, it is recommended that only the leaves should not be removed. Because the petioles are thick and brittle and the leaves are removed from the base, the stems are prone to large wounds and are not easily healed. The leaves can be removed completely or in large portions. Causes the petiole to dry off faster. In addition, it should be noted that it is best to have several consecutive sunny days when removing the leaves, which will help the wound heal, and it will not be easy to infect the disease. After the leaves are removed, streptomycin 4000 times or natural brassin can be sprayed to prevent disease infection.

2, wipe melon. If the time difference is too large, it will easily lead to more crooked melons and big head gourds. It is best to wipe out the melon on the day before flowering or on the day of flowering, 9-11. The cultivation of summer cucurbits in the greenhouse, seedling development period is mostly in the short-day, low-night temperature environment conditions conducive to the formation of female flowers, generally grow to 3 to 4 true leaves when there are female flowers occur, even with female flowers, more than one section female flower. Too much female flowers are allowed to grow and develop, which inevitably consumes a large amount of organic nutrients, affects the growth of plants and young melons, causes a lot of falling melon, and causes a serious decline in the yield. Therefore, it must be eliminated early to reduce nutritional competition and promote melons. The number of sparse female flowers should be determined based on the growth of the melons. Weak growers should wipe out the root melon first, and then leave a female flower every three quarters later; the melon grows strong and can leave root melons, but it should be harvested early and leave a female flower every two or so.

3, falling vines. In the later stages of the squash, the plants are tall and some are even more than 2 meters, which brings inconvenience to the management of picking, spraying, etc. It is necessary to pay attention to the timely fall of vines. The stalks that fall on the ground can be buried with soil to promote the regeneration of adventitious roots and improve the ability of roots to absorb water and fertilizers. , delaying plant senescence and increasing late yield
