The field experiments are carried out to analyse the soil water deprivation and water requirement of crops during the whole growth stages under different irrigations in gravel-covered mulched fields.The result showed that 15mm one-time irrigation can improve the soil moisture around and it can be to meet the water needs for nearly 10d.The water requirement has 4-sensitive period during the watermelon growth,in which the greatest demand for moisture occurred during the early stage of flesh and maturity.There are some differences between soil moisture in the gravel-covered mulched field in various years.Normally water content is higher in aged fields(above 10 years old) than that in the new fields.
