Different methods of water retention affect the growth of lemon to some extent. Soil moisture tester studies have shown that the use of water retaining agents has a certain impact on the soil temperature and humidity of lemon cultivars, and presents different significant differences. Adequate soil moisture growth provides favorable conditions. Because of the particularity of the physiological differentiation of lemon flower buds, water promotes the transitional vegetative growth of the lemon and improves flowering.
The main reason for the existence of the nugget effect on the soil moisture in the 10-20cm layer was the difference in vegetation status. The underground biomass was mainly distributed in the 0-10cm soil layer in the alpine grassland ecosystem, and the root distribution was 10-20 cm. The layer makes the internal change smaller than the sample size. Another reason is that the difference in vegetation coverage results in a strong vegetation change scale. The soil moisture tester's numerical analysis standard deviation and coefficient of variation of vegetation coverage are 13.93%, 47.99%, absolute difference and relative. The difference is very large.
The soil water tester was further used to analyze the effect of soil water on the 40-50cm layer, which was mainly related to differences in soil physical properties such as soil thickness and soil parent material. The deep gravel content in the soil increased and small-scale variability increased. Another important reason was that The effect of deep soil melting on the spatial distribution of water in the active layer of frozen soil will gradually migrate to the bottom of the active layer as the frozen soil melts, resulting in uneven distribution of moisture in permafrost regions.
The larger values ​​of 0-5 cm and 5-10 cm layer soil moisture analyzers reflect the higher degree of variation, and different micro-topography and vegetation coverage of surface soil. The soil moisture tester values ​​reflect the high degree of changes in soil moisture and vegetation coverage in the 40-50 cm layer, further confirming the results of the gold block value.
