Cultivation of Trichosanthes has failed, and planting techniques and field management need to be strengthened.

The failure of planting Trichosanthes may be due to the problems of seedling quality, planting method, field management, pest control and so on. Therefore, in order to prevent the failure of planting Trichosanthes, we first need to select high-quality seedlings, and then choose deep soil, loose soil, sufficient fertility soil for planting, planting methods can use colonization and close planting, the process of management needs reasonable fertilization, reasonable collocation of male plants, and active control of firefly, charcoal maggot disease and other diseases.

There are many reasons for the failure of planting Trichosanthes, which may be due to the quality of the seedlings. If there is no problem with the seedlings, it must be that the planting techniques fail and there are problems in planting management, so we must follow the correct planting methods. Whether in soil selection, watering and fertilization, or in the prevention and control of diseases and insect pests, the planting techniques of Trichosanthes should pay attention to the following aspects Let's study together.

1. Planting site selection

When choosing the planting site, Trichosanthes must choose sandy soil with deep soil layer, sufficient fertility, loose soil and convenient drainage and irrigation. Trichosanthes is a vine, like sufficient light and warm environment, afraid of waterlogging, so we need to pay special attention to the choice of planting land, starting from the soil, if it is not very suitable for planting soil, we need to fundamentally improve the soil, and then plant.

2. Planting method

When planting Trichosanthes, first carry on the soil deep ploughing, ridge drying, raking equal process, in the soil treatment, need to put organic fertilizer under the soil, such as farm fertilizer, phosphate fertilizer, boron fertilizer and so on, and then fill a layer of soil, and then fill it with a layer of sand.

Planting can be used when planting and close planting, the general choice of planting in early April, after frost-free weather can begin to plant, to reasonable close planting, generally planting more than 260 mu per mu. Because Trichosanthes is a vine, it needs a scientific scaffolding, which is usually made of cement columns, because they are durable, and bamboo or wood can be used if they are in mountainous areas, which can save costs. When building a fight, we must consider the convenience of the follow-up to hit pesticides, Shunteng, cungua and so on.

3. Field management

During the growth period of Trichosanthes kirilowii, male plants should be matched reasonably, 4-5 plants per mu of land should be selected to be put on the shelf, and the rest can only grow on the ground. During this period, we should also pay attention to reasonable fertilization, when the seedling is 1 foot long, we can start fertilization, the frequency is about once a week, fertilizing as far as possible from the seedling distance. After flowering and fruiting, topdressing according to its growth, especially in the flowering and fruiting period, requires a large number of fertilizers, anthers and fruit preservatives.

4. Disease and pest prevention

The most common diseases and pests of Trichosanthes are firefly and roll borer, and different potions should be used to control them in different periods. In the seedling stage, firefly pests are easy to occur, which can be controlled with dimethoate and great heroes. The insect pests of Chilo suppressalis are easy to occur in the flowering and fruiting period, which can be controlled by spraying with high-efficiency cyanide-recording polyester and insecticidal water.

In addition, there are some diseases and insect pests that harm Trichosanthes: root knot nematode disease, vine blight, anthracnose, bacterial corner spot, melon cucumber borer, melon aphid and so on. At this time, we need to choose different drugs for prevention and control according to different diseases and insect pests.
