Simply understand what main vines, secondary vines, and tertiary vines are
This article introduces the relevant knowledge of fruits and vegetables, simply understand what main vines, secondary vines, and tertiary vines are. Detailed introduction is provided below.
You don't know if you don't plant melons, and only after planting do you know about the terms such as main vines, secondary vines, and tertiary vines. Some gardening friends ask what main vines are, so I might as well explain the other types in simple terms, hoping to provide some references for gardening friends.
So-called vines refer to the slender, non-erect stems of plants. For example, the vines of cucumbers need to be supported by stakes to grow upright, otherwise they can only crawl on the ground. This is true for most melon plants, such as watermelons, luffas, and muskmelons.
In layman's terms, the main vine is the one that exists from the beginning. From germination to leaf growth, the first tendril that grows is the main vine, which is usually relatively thick and sturdy (you can refer to the illustration in the text. The drawing is not professional, the main purpose is to show the position of the main vine, secondary vine, and tertiary vine to gardening friends, please ignore that it is a watermelon seedling).
Secondary vines are the tendrils that grow from the petioles of the main vine leaves. These tendrils grow from the base of the leaves of the main vine, which is the petiole area, after the main vine has grown to a certain extent. They can also be branches that grow from the topped part of a muskmelon.
Tertiary vines are the tendrils that grow from the secondary vines.
Let's take a look next at where the fruits of the common melons we see are borne!
Muskmelon: Secondary vines and tertiary vines bear fruit, usually topping at about ten leaves and leaving 2 or 3 strong secondary vines, and watching the tertiary vines.
Winter melon: Main vines bear fruit, no topping.
Pumpkin: Both main vines and lateral vines can bear fruit, but usually lateral vines bear fruit.
Watermelon: Main vines bear fruit, no topping.
Cucumber: Both main and lateral vines bear fruit, no topping.
Luffa: Both main and lateral vines bear fruit. The secondary vines and old leaves should be removed before leading the vines onto a trellis, no topping.
Bitter melon: Mainly the main vines bear fruit, but the lateral vines also bear fruit. There is little fruiting on the lateral vines below 50 cm from the ground, so they should be removed in time when leading the vines. If the lateral branches above the ground grow too densely, they should also be removed appropriately. In short, the growth of the main vines should be ensured to take advantage of their fruiting.
Gourds: Male flowers are mostly found in the middle and lower parts of the main vines, while female flowers are mostly found in the upper parts. Lateral vines can bear female flowers from the 1st to 2nd internodes, so the main fruiting is from the lateral vines. To make the main vines produce lateral vines early and more female flowers, the top bud of the main vine can be removed (also known as topping) after the main vine has grown 4 to 6 internodes.
