Tang Yuwen, a technician from Jixian County of Jinzhong City, Shanxi Province, wrote in a letter asking: Their local residents like to eat pumpkin. The market price of pumpkins in recent years is also good. Many vegetable farmers want to expand the planting area, and they have little knowledge of the pumpkin's high-yielding cultivation techniques. They hope the newspaper’s Experts can provide them with some management techniques in this area! Answer: Comrade Tang Yuwen, as a first-line agricultural technician who is in constant contact with producers, can actively seek technology for local farmers. It is the “blessing†of local farmers! During the cultivation and management of pumpkins, the following methods can be used to increase the yield by more than 30%. Top picks. When the melon vine grows to 2 meters, the main vine growing point is removed, and 3-4 vines can grow. Racking. When the branch reaches 2 meters in length, the vine is drawn onto a scaffold, taking care not to break the vine. After the scaffolding of the scaffolding, the pest will be greatly reduced, which will greatly increase the rate of sitting. pollination. Using artificially assisted pollination, the effect of increasing yield is particularly significant. The method is: to quickly open pollinated female flowers covered with melon leaves to prevent the intrusion of rain, the next day at about 9 o'clock, the male flowers on different plants are taken to cover the female flowers, and the male flowers of the cover can be removed after 2-3 days. . Pick leaves. On the vines that have already blossomed, timely removal of the leaves of the foot and old yellow leaves, and the removal of 30% of the male flowers, can both ventilate and transmit light, while avoiding the consumption of nutrients. Buried stems. In the late stage of pumpkin growth, that is, after 2-3 batches of melons, some waxy yellow leaves are removed from the roots, and the adventitious roots growing on the vines are buried, which can increase production by 30-40%. The method is: use fertile garden soil mixed with a small amount of organic fertilizer and quick-acting fertilizer, buried 4-6 stems, to ensure that there is enough buried stem length, if the length of the stem between the ground and the frame is too short, you can combine the shelf surface The vines are properly retracted from the main stalk, but they should not be pulled or moved. The soil layer needs to be buried tightly to facilitate the growth of adventitious roots. At the same time, special attention should be paid to grasping the time of burying stem If it is too early, it is easy to cause leggy; (Xia Jiachao, Dazhiping Town, Badong County, Hubei Province)
