Improve the watermelon seating rate skills
1. Artificially assisted pollination. During the opening of the second and third female flowers of the main vine, a sunny day was chosen to pick the male flowers and remove the petals. The anthers were gently applied to the male stigma. Rainy days can be covered with a small plastic bag or paper bag before opening the female flowers for artificial pollination. According to experiments, compared with natural pollination, artificial-assisted pollination can increase the rate of seat-seeds by more than 10% on sunny days and increase the rate of seat-seedlings by more than one-fold on rainy days. 2, cut roots. When the watermelon grows to 4 to 5 true leaves, and there is no earthworm growth, use a spatula to straighten it down at a distance of 13 cm from the root of the plant. The deeper the better, you can also use the shovel and pear to make a deep turn, but pay attention. Can not damage the main root, can not turn over the soil, but one by one to loosen the soil, its purpose is not only to protect soil, mainly to cut off the lateral roots. Doing so can inhibit the vegetative growth of the plant, avoid the phenomenon of prolongation of the plant and slenderness of the vine, make the root growth of the plant fibrous roots robust, and form a huge root system, in order to facilitate the flowering and squash. 3, pinch stems. In the back of the squash on the stalk, forcefully pinch, you can hear a "snap" sound, so that the baby can be stable, prevent melon.
