Demand for soil moisture is particularly important for wheat growing too long in winter, and soil moisture is an important factor affecting wheat growth and yield in winter. Soil moisture can be quickly monitored and measured by a soil moisture tester. Today we use a soil moisture tester to study the importance of winter wheat growing in long-term soil moisture.
The lack of water resources is a limiting factor for the efficient and sustainable development of agriculture in the North China Plain. Soil drought is a limiting factor that restricts the crop's production potential. Therefore, how to improve the utilization efficiency of irrigation water in the region has become a research hotspot in agricultural water conservation. The combination of planting methods and water-saving irrigation has become a new research direction in recent years, such as Zhang Yuanpei's research on the water-saving effect of mulching on winter wheat, and Lv Dianqing’s research on soil moisture distribution under cultivating ridge and furrow. As a soil and water conservation combined cultivation method, the ridge and furrow cultivation changes the topography, blocks part of the runoff, relatively increases soil water storage, improves water use efficiency, and reduces soil loss. Ridge cultivation and furrow planting have the effect of increasing soil water storage.
Drip irrigation is local irrigation. The loss of evaporation between the trees and deep leakage is small, and the water can be transported to the roots of crops more concentratedly. Therefore, the water use efficiency is higher. China's current research on drip irrigation mainly focuses on crops with higher economic value, but with the increasing scarcity of water resources, drip irrigation technology will be increasingly applied to field crops. Winter wheat is an important food crop in the north of China, and its soil water deficit during the growth period. However, there is still little research on the impact of quantitative irrigation on crop growth and development under drip irrigation conditions, which affects the effectiveness of water-saving benefits.
The purpose of studying soil moisture is to provide a theoretical basis for farmland irrigation, and to understand the distribution of soil moisture at different levels of farmland and the conditions of crop absorption and utilization through research on soil moisture, so as to achieve the purpose of effectively improving water use efficiency, and to find a suitable area for the region. Winter wheat irrigation system. The experiment uses winter wheat as the tested crop, under the conditions of ridge and furrow sowing, it conducts quantitative and regular local irrigation through drip irrigation, and studies the dynamic change of farmland soil water, in order to provide theoretical basis for guiding farmland irrigation.
