The solar terms in October have cold dew and frost. Generally, the frost begins at the end of October, and the warm vegetables enter the end of the harvest. The cold-tolerant and semi-hardy-tolerant vegetables enter the vigorous growth season, and the agricultural activities of the vegetable fields are transferred to the protected areas.
1. In the first ten days of October, the winter flowering and cabbage seedlings were bred, and the seedling age was 30-35 days. After the planting, the mulching film covered the winter.
2. In mid-October, the large-scale zucchini in the solar greenhouse began to raise seedlings, and the seedling age was 15 to 20 days. Wintering zucchini is also a kind of cultivation method with good benefits. It can be cultivated like cucumbers, and can grow about 30 seeds per plant. The benefit of mu can reach 30,000 yuan.
3. Green onion cultivation: In October, the growth rate of green onions is accelerated. In order to increase the length of “white onion†and improve the quality of green onions, the soil shall be cultivated for 2 to 3 times, and the height of each soil shall not be less than 10 cm. Heart leaf.
4. Strengthen the management of radish and Chinese cabbage in the middle and late period: In October, the radish grows into the rapid expansion period of the fleshy roots, and the Chinese cabbage enters the period of the heart-filling period. At this time, the management of water and fertilizer should be strengthened, and the occurrence of pests and diseases should be prevented to obtain high yield.
5. The onion is planted at the end of October to November: when the onion seedlings reach 4 to 5 leaves and the stem diameter is about 0.5 cm, the colonization standard is reached. The mulch is sprayed with “cut grass†and the mulch is planted. The planting is 2.2 to 26,000.
6. In some areas, early spring greenhouses, impotence and other multi-layered peppers and eggplants began to grow in cold sheds.
7. When planting wheat at the beginning of October, it can be used as interplanting vegetables in the reserved zone of wheat to promote grain, cotton, vegetables and melons. In the case of "Muggle" or "McPurin" interplanting, the reserved zone left by the planting of wheat is cultivated and fertilized, and intercropped with cold-resistant vegetables such as spinach, garlic, cabbage, black rape and so on.

1. Considering the limitation of storage space and storage cost, as well as the fact that video recording in public places such as residential areas is a prerequisite for multi slot and a certain degree of clarity, video recording is generally deleted once a week or so. 15 days for general entertainment venues, 26 days for financial industry, and 3 months to half a year for banks, depending on the current venue regulations
2. The length of the storage time of the monitoring video is generally related to the following points: the capacity of the host's hard disk. Generally, a camera needs about 0.3G-0.5G of hard disk capacity for 24 hours of continuous video recording. Different systems have different parameters, the minimum is 0.15G/24 hours;
3. The number of cameras. The more cameras, the more capacity required. Also, the selection of the resolution and picture quality of the recorded picture will also affect the capacity required for video storage;
4. The video recording mode will also affect the space required for storage. The video recording mode is generally divided into [Mobile Video Recording] and [Continuous Video Recording]. The former means that the host starts to record when a moving object passes through the monitoring range, and does not record at other times. This can reduce the storage space required for video recording; On the contrary, continuous video recording is 24-hour continuous video recording.
