1, upside down
There are many ways to manage watermelon vines. The first way is to turn the vines upside down. Inverted vines are very helpful to the growth of watermelon, which can promote the growth of vines, change the growth direction of vines, and make them absorb more nutrients and water, thus improving the yield and fruit quality of watermelon. Watermelon vine turning time is generally carried out when the plant grows about 5 real leaves. When the vine is inverted, firstly, put a piece of soil on the side of the base of the vine opposite to the growth direction of the main vine, so that the vine can lie on the ground obliquely along the extension direction.

Managing vines is also a common vine management method in watermelon planting. Because the vines of watermelon have strong growth ability, if the vines are ignored, then the vines are easily intertwined. It affects the growth between vines, so we should pay attention to the management of the left and right vines after the vines are inverted. Prune the vines roughly 2-3 times a week when the vines are flourishing. When arranging vines, it is necessary to straighten the vines manually so that the melons and vines are evenly distributed on the surface of the frame. Pay attention to put the rattan tips out of the border back into the border in time and fix them.
Step 3 squeeze vines
Pressing vines can make melon vines in a directional state and promote them to produce adventitious roots, thus increasing the nutrient absorption area of plants. Generally, press the vines when they grow to about 45 cm. Cover the vines with soil first, and then press them once every five knots, usually four times, according to the number of knots of the vines. It should be noted that the front and rear sections near the melon can not be pressed. The time for pressing vines should be in the afternoon of sunny days, and the humidity is relatively high in rainy days and sunny days, so vines cannot be pressed.
Step 4 prune vines
The main purpose of pruning vines is to regulate the vegetative growth and reproductive growth of watermelon. Usually pruning vines should be carried out in June-July. Generally, there are single-vine type and multi-vine type. Single vine type is to cut off all the vines of watermelon plants, and then only keep the main vines. So the multi-vine style is to keep the thick vines on the main vine and the main vine for about 4 knots, and then cut off the redundant vines. We should choose a reasonable pruning method according to the characteristics of planting varieties, and also consider planting density, soil fertility and other factors.
