果树在整个生命活动中,都需要一定的水分。我县处于滨海盐碱地区。历年来,春风大、干旱少雨,水分大量蒸发,盐分随之上升,集结于地表,返盐现象十分严重,这对果树花足、叶茂、多结实十分不利。根据几年对盐碱地果树观查表明,果树随着地温逐渐升高,树体内生理活动机能渐趋强烈,花、叶芽相续展放, Fruit trees need some water throughout their life activities. My county is in the coastal saline area. Over the years, the spring breeze, drought, rain, a large number of evaporation of water, salt rise with it, the concentration of the surface, return to salt is very serious, which fruit flower enough, leafy, and more solid is very unfavorable. According to several years of observation on the saline-alkali fruit tree, the fruit tree gradually increased with the ground temperature, the physiological activity of the tree became stronger and stronger,
