In order to increase the yield of pumpkin, in the cultivation management process, the following methods can be adopted to increase the yield.
Topping. When the vine grows to 2 meters, the main vine grows out and you can grow 3-4 vines.
Rack. When the vine grows to 2 meters, put the vines on the scaffolding, taking care not to break the vines. The pumpkins after the scaffolding will greatly reduce the pests and diseases, so that the sitting rate will be greatly improved.
pollination. The use of artificially assisted pollination has a particularly significant effect on yield increase.
The method is as follows: the female flower which is open and pollinated is covered with melon leaves to prevent rainwater from invading. At about 9:00 in the morning, the male flower on the different plant is taken over the female flower, and the male flower can be removed after 2-3 days. .
Picking leaves. On the melons that have been flowering, the leaves and the old yellow leaves are removed in time, and 30% of the male flowers are removed, so that the air can be ventilated and light, and nutrient consumption can be avoided.
Buried stems. In the late stage of pumpkin growth, that is, after 2-3 batches of melons are removed, some yellow leaves are removed from the roots, and the adventitious roots growing on the vines are buried, which can increase yield by 30-40%.
The method is as follows: a small amount of organic fertilizer and quick-acting fertilizer are mixed with the fertile vegetable garden soil, and the stems of 4-6 knots are buried, and it is necessary to ensure sufficient length of the buried stem. If the length of the stem between the ground and the rack is too short, the rack surface can be combined. The vines are properly retracted from the main stem, but it is forbidden to pull and move the stems. The soil layer needs to be buried to facilitate the growth of adventitious roots. At the same time, special attention should be paid to the time of burying the stem. Too early, it is easy to cause a long time; too late, the roots of the roots grow slowly.
Circular saws are most frequently used Power Tools on woodworking. They are categorized according to their drive motor, the type of depth control they use, their cutting depth and power input. Circular saws are available in general-purpose and special versions. Typically, hand-held circular saws are mounted on a base plate.
