Irrigation regimes for drip irrigation of watermelon in mulched and non-mulched fields

چکیده
In most regions of Uzbekistan, the biological productivity climate will decrease by 10-20%, and in some 30-40%, steppe semi-desert zones expand further. Therefore, it is impossible to effectively develop irrigated agriculture without development implementation resource water-saving technologies aimed at increasing efficiency water use. We carried out our experiments based on optimal irrigation norms for cultivation watermelon plants mulched fields drip irrigation, keeping differentiated soil moisture (60...70...60%, 65...75...65%, 70…80...70% 75…85...75% SAM) defined norm. this case, limit before 60...65...70...75% SAM according experimental options 0-20 cm layer “planting - shatrik” period 0-40 “shatrik bloom” period; The 0-50 was maintained 70...75...80...85% during “bloom fruit formation” “ formation ripening” period.

Spatial Variability and Lateral Location of Soil Moisture Monitoring Points on Cotton Mulched Drip Irrigation Field
This experiment was conducted from April to September in 2009 in Baotou-lake Farm of Korla city, Xinjiang region, China. Two experiment schemes were designed for analyzing the spatial variability and lateral orientation of monitoring points for soil moisture. In scheme 1, 44 monitoring points were positioned with sampling depth of 0~60cm. In scheme 2, 20 monitoring points were placed with sampl...
متن کاملPartitioning of Cotton Field Evapotranspiration under Mulched Drip Irrigation Based on a Dual Crop Coefficient Model
Estimation of field crop evapotranspiration (ETc) and its partitioning into evaporation and transpiration, are of great importance in hydrological modeling and agricultural water management. In this study, we used a dual crop coefficient model SIMDualKc to estimate the actual crop evapotranspiration (ETc act) and the basal crop coefficients over a cotton field in Northwestern China. A two-year ...

Soil particle size distribution (PSD), one of the most important soil physical attributes, is of great importance to soil water movement, soil erosion and soil solute migration. In this study, the soil PSD of 563 soil samples from the mulched drip irrigated cotton fields in Xinjiang of China were measured by laser diffraction particle size analyzer. The soil PSD characteristics and its relation...
