This period is a progressive stage of vegetative growth and reproductive growth of corn, and is a critical period for field management. Therefore, the training of technology demonstration households at this stage is particularly important. I took 3 days to provide technical training guidance to the model households.

First, the top-of-the-line tweezers period is the period in which corn needs the most fertilizer and the maximum fertilizer strength. At this time, topdressing is needed to prevent the phenomenon of de-fertilization. Fertilize according to soil fertility and corn growth. 15-20 kg of urea per acre, topdressing should be applied to the soil 10 cm deep, cover the soil after fertilization, do not spread the surface to improve fertilizer utilization.

Second, cultivating and cultivating soil can loosen the soil, improve the ventilation and water and fertilizer supply, promote root growth and prevent plant lodging. At the same time, weeds can be removed and water storage can be done.

Third, pest control This period is mainly to control corn borer and aphids. You should always go to the field to check the occurrence of pests and diseases. Corn borer can be controlled in the first half of July with the Trichogramma (the bee card is uniformly distributed by the township agricultural station).

(1) Number and number of bees to be released: 15,000 heads of red-eye bee are released per acre (16 small pieces per bee card, 16 small acres per bee card), the first time to put 7,000 heads, the second time 8,000 heads.

(2) Number of bee-keeping points: 1 release point per acre, in the corn field where Trichogramma is released. Starting from the side ridge, the 20th ridge is the first bee ridge, 13m (20 steps) along the first bee ridge is the first release point, and then the ridge is 26m (40 steps). The second release point, and so on, is pushed to the ground by the first release ridge, and the ridges are separated by 40 ridges as the second one, and so on. When releasing, it is necessary to set the point according to the wind direction and wind speed. If the wind speed is large, the distribution point and release amount should be appropriately increased on the upper part, and the downwind head can be appropriately reduced.

(3) Release method: select the middle leaf of a relatively high corn plant at the point where the bee is placed, and the bee kaka is in the middle of the corn leaf (the blade is cut along the veins by about 3-4 cm, and the bee is stuck in it) The back side is 1/3 of the base of the leaf. The corn aphid can be uniformly sprayed with 50% anti-polycarb 3000 times solution or 40% omethoate 1500 times solution.

Digital Hotel Safe

A digital Hotel Safe is a secure storage device found in hotel rooms that uses electronic technology to provide guests with a secure place to store their valuables. Unlike traditional hotel safes, which typically use a physical key or combination lock, digital hotel safes use a digital keypad or touchscreen interface to allow guests to set their own unique passcode.

Digital hotel safes offer several advantages over traditional safes. Firstly, they are more convenient to use, as guests can easily set and change their own passcodes without needing assistance from hotel staff. Secondly, they provide a higher level of security, as the passcodes are typically encrypted and more difficult to guess or crack compared to physical keys or combinations.

In addition to the passcode entry, digital hotel safes may also offer additional security features such as an audit trail, which records the date and time of each access attempt, as well as a tamper-proof design to prevent unauthorized access.

Digital hotel safes come in various sizes and designs to accommodate different types of valuables, such as laptops, jewelry, passports, and cash. They are typically mounted securely to a wall or inside a cabinet to prevent theft or unauthorized removal.

Overall, digital hotel safes provide guests with a convenient and secure way to store their valuables during their stay, giving them peace of mind knowing that their belongings are protected.
