Seeds are the initial state of a plant, and many plants grow through seeds. There are a series of work before the seeds are seeded, such as seed storage and seed quality inspection. The seed quality test is a very important project. For example, the analysis of seed clarity, the determination of seed grain weight, the seed moisture content and other parameters must be measured one by one, and then the seeds should be selected according to relevant regulations. The seed wind analyzer is one of the most frequently used instruments in the inspection of seed quality, and the seed storage can only be carried out after the seeds have been subjected to quality inspection. Seed storage also has corresponding precautions. Below we analyze under specific circumstances, under which circumstances, we should not put soybean seeds into storage as soon as possible.
First, it is not advisable to store at a high temperature: Soybean seeds are rich in protein and are easily degraded under high temperature conditions. Therefore, soybean seeds must be stored at low temperature. In particular, dried soybean seeds must be spread out after cooling before they can be stored in storage.
Second: It is not advisable to store in rainy or damp weather: scientific arrangements must be made before the acquisition to understand the recent meteorological information, and to seize the sunny and dry weather assault acquisition. Rainy days when the air is wet, prohibit the purchase of storage.
Third: Seeds should not be stacked too high: Soybean seeds should be stored at a temperature below 15°C and moisture content below 12%. Stacking height should not exceed 1.5m, and bags should be 8 standard sack heights. If one of the temperature or moisture is higher than the above criteria, the stacking height must be reduced accordingly. Between the wall and the wall, there must be a reasonable space between the wall and the wall.
Fourth: should not be stored together with chemical fertilizers or pesticides: storage of soybean seeds to special warehouse to do, the library can not stack fertilizers or pesticides and other items at the same time, in order to avoid volatile gases into the embryo, resulting in the loss of soybean seed vitality.
Excavator proportional system refers to the hydraulic system that controls the movement of the excavator's arm, bucket, and other attachments. This system is designed to provide precise and proportional control over the excavator's movements, allowing the operator to perform delicate and precise operations with ease.
The excavator proportional system uses a series of hydraulic valves and sensors to control the flow of hydraulic fluid to the various components of the excavator. These valves are controlled by the operator's movements of the joystick, which sends signals to the hydraulic system to adjust the flow of fluid to the various components.
The proportional system allows the operator to control the speed and force of the excavator's movements with great precision. This is particularly important for tasks that require delicate and precise movements, such as digging around sensitive underground utilities or performing demolition work in tight spaces.
Overall, the excavator proportional system is an essential component of modern excavators, providing operators with the control and precision they need to perform a wide range of tasks safely and efficiently.
