菠菜较耐寒,在低温条件下较易贮藏。尖叶品种比圆叶品种耐贮一些。贮藏方法颇多,今简介两种沟贮法: 一、分两个阶段:①临时贮藏。立冬前,土壤快要冻结时,把菠菜连根拔出,摘去黄叶,捆成1—1.5公斤一捆,埋于35厘米宽、10—12厘米深的沟里,上边盖4—6厘米厚的湿土(但不要太湿),以不露菠菜叶为准。②正式贮藏。选择背风干燥处,挖12—15厘米深,25厘米宽的沟。立冬以后,取出临时贮藏的菠菜,根朝下立摆于沟里,不要过紧,以防伤热。摆好后用干沙盖叶子,厚1—2厘米,上边再盖厚6—10厘米土,要高出地面,以防雨水或雪水渗入沟里。特别注意不能伤热,掌握叶冻根不冻,到最严寒季节在沟边盖上一层乱草或秸杆。二、挖55厘米深、65厘米宽的沟,于立冬到小雪期间,把菠菜根朝下摆在沟里,摆满后盖一层干沙,埋住叶子。沟上边用成捆秫秸或玉米秸盖上。上边盖土,厚15—18厘米,留两个通气孔。菠菜下沟初期气温高,昼夜打开气孔,保持0—2℃,以
Spinach more cold, easier storage under low temperature conditions. Spike leaf varieties more resistant to storage than some. A lot of storage methods, this brief introduction of two kinds of ditch storage method: First, divided into two stages: ① temporary storage. Before winter, when the soil was about to freeze, pull the spinach uprooted, remove the yellow leaves and bundle it into a bundle of 1-1.5 kg, buried in a 35 cm wide, 10-12 cm deep ditch with a 4-6 cm thick top Wet soil (but do not be too wet) to not reveal the spinach leaves prevail. ② formal storage. Choose leeward dry place, dug 12-15 cm deep, 25 cm wide ditch. After the beginning of winter, remove the temporary storage of spinach, root pendulum placed in the ditch, do not be too tight to prevent heat injury. Set the dried sand cover with leaves, 1-2 cm thick, then cover 6-10 cm thick soil, to be higher than the ground, to prevent rain or snow into the ditch. Pay special attention not to heat, to grasp the frozen leaf root freeze, to the darkest season in the trench cover a layer of chaos grass or straw. Second, ditch 55 cm deep, 65 cm wide ditch, in the beginning of winter to light snow, spinach rooted in the ditch down, covered with a layer of dry sand cover, buried the leaves. Top with a bundle of straw or corn stalks covered. Cover the top of the soil, 15-18 cm thick, leaving two vents. Spinach under the ditch early high temperature, open the stomata day and night, to maintain 0-2 ℃, with
