Effect of Applying Water Retaining Agent on Soil Moisture
The application of water retaining agent can make the soil moisture accumulate at the water injection origin, and the horizontal and vertical moisture diffusion of the soil moisture is slow, which can provide sufficient water and nourishment for seed germination and seedling growth. Different water-retaining agent application rates have a greater influence on the top soil of the soil and the water storage capacity of 1m depth soil after water sowing. The treatment with a large amount of water retaining agent and the water retention effect of the water-retaining agent seed dressing treatment have a significant effect, so that the soil water storage capacity is more than sowing Increased by 1.23 mm and 2.25 mm. The determination of soil moisture can rely on the wireless public opinion monitoring system. This soil moisture analyzer can achieve wireless data transmission without the need of data lines. It is very convenient.
The lack of water quantity is the main limiting factor for the healthy operation of agricultural ecosystems and the increase of crop yields in the arid and semi-arid regions of northern China. In arid and semi-arid areas, due to lack of winter irrigation or winter irrigation, the lack of fixed quotas, coupled with spring drought and drought, led to serious spring drought, resulting in insufficient soil moisture conditions, and even the phenomenon of weak seedlings, few seedlings or even seedlings. The lack of soil moisture will have a very serious impact on the growth of corn. Therefore, we will use the multi-point soil temperature and humidity recorder to measure the current changes in soil moisture from time to time during corn cultivation and make timely remedial measures. Because the early growth and development of corn has a great influence on its later growth and yield, how to promote the early growth and development of corn is also very important. Applying the appropriate amount of water retaining agent during watering sowing can cause the soil moisture to accumulate at the water injection origin. The horizontal and vertical moisture diffusion of the soil moisture is slow. It can provide sufficient water and nourishment for seed germination and seedling growth, and can promote corn seed. It germinates, makes the seedlings strong, has a well-developed root system, and grows vigorously in the early stages. It is an effective measure to resist spring drought, preserve seedlings, and preserve strong seedlings. In the drought-free or semi-arid regions where there are no water conservancy facilities in the dry or semi-arid areas of northwest China, water-retaining with water-retaining agents is a good method for sowing drought and should be vigorously promoted. With the declining agricultural water resources and the development of water-saving agriculture, it is very important to further explore the combination of water-injection and other dry farming technologies. Timed positioning of soil moisture meters is also a very frequent instrument used in soil moisture determination experiments.
