Pumpkin is a common vegetable. It can be eaten and eaten. It can also be used to make porridge and processed into agricultural and sideline products. It has good planting benefits. So, do you know how to plant it is the high rate of pumpkin fruit set? I don't know, I can follow the small series to learn how to plant pumpkins and produce 6 big tricks. Pick your heart at the right time: When the melon grows to a length of about 2 meters, pick up the main vine growth point, so that the main vine grows 3 to 4 branches, which promotes the flowering and melon. Prevent the leader: The melons grow long and cause fewer pumpkins. In order to prevent the application of nitrogen fertilizer and the application of phosphorus and potassium fertilizer, you can cut a slit of 1~1.5 cm long and 0.5~0.8 cm deep in the longitudinal direction of 25~30 cm from the root of the melon. A piece of charcoal in the middle can suppress the growth of the melon. Build a melon shed: When there are conditions, when the vines grow to 2 meters long, the vines are put on shelves. This can reduce pests and diseases and increase the rate of sitting. "Spray on the top" technology: Because the pumpkin head is relatively large, it is necessary to do a good job of topdressing management in time to improve the yield and quality. At present, the newer technology is "sprayed leaf fertilizer + root drenching and fertilizing". From the beginning of the pumpkin results, the foliar fertilizer is sprayed once every 7 to 10 days, and the nutrients required for the growth of the pumpkin are directly absorbed by the stomata of the pumpkin leaf surface, which is better than the soil fertilization to damage the root system. When spraying, it is effective to spray on the back of the leaf, and it can also be sprayed with the pesticide. Pay attention to avoid the high temperature time at noon, and the evaporation of the back surface fertilizer liquid is too fast to reduce the effect of spraying fertilizer. While spraying the foliar fertilizer, the organic fertilizer is applied to the roots, which is better than the traditional soil dressing. The application of fertilizer does not damage the roots, and the effect is quick. The absorption of crops is easier and more comprehensive, especially for farms with a large planting area, and it is more suitable to use fertilization. At present, there are many kinds of foliar fertilizers and fertilizers on the market. The growers can choose practical, high-efficiency and organic fertilizers according to their own economic conditions. Foliar fertilizers are recommended to choose Bond's first fruit to add potassium dihydrogen phosphate. It is recommended to apply organic fertilizers, such as Jin Shi Bao or Bond, to activate the soil (especially the plots where symptoms of compaction have occurred). These organic fertilizers are different from other varieties and they can promote crops. The root system develops in depth, conveying better nutrients for the leaves , and ensuring the effect of high yield and stable yield. Auxiliary pollination: The pollinated female flowers will be opened soon, covered with melon leaves. The next morning, 8~9 o'clock, the male flowers of the different plants will be covered on the female flowers, and removed after 2~3 days. Remove yellow leaves: On the melons that have been flowering, remove the leaves and the old yellow leaves in time, which can reduce the consumption of nutrients and promote the pumpkins. Pumpkin planting wants to achieve high yield, the method is very simple, only need to pay attention to water and fertilizer management, timely picking, pruning. The above is the detailed operation steps, please hurry and find out.
New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.).
