Results showed : ( 1 ) if the proportion of water in the soil is lower than wilting coefficient, and if irrigating water is very little, ( irrigating water is spreading horizontally and vertically ) the relationship between the horizontal width ( x ) and the ? rtical depth ( y ) is remarkable. the equation is y - 0. 02 12x2 + l. 8546x - 17. 88. the related coefficient is r = 0. 9350
結果表明: ( 1 )在土壤含水量低於萎蔫系數的乾燥條件下,進行微量穴滴灌,滴灌點土壤濕潤面直徑x與最大垂直面滲透深度y呈顯著相關,數學模型為: y = - 0 . 0212x ~ 2 + 1 . 8546x - 17 . 88 ,相關系數r = 0 . 9350 ( 2 )在微量補水灌溉情況下,只有灌水量大於4000ml /穴,才能使滴灌水滲透到20cm以下土層,達到作物根系集中層,否則水分很難被作物吸收,造成滴灌水的浪費。Drip irrigation has many strong points, such as timely and adequate irrigation water, conserving water and energy. it is an effective measure of water - saving irrigation. and many experts devote their time to the study on drip irrigation
