一、菠菜菠菜,原产波斯(今伊朗),唐朝传入我国,至今1300多年。菠菜叶肉厚软,碧绿青翠,为四季餐上常蔬。菠菜四季均可种植,但在北方则需贮藏秋菠菜来供应冬季市场。埋藏法贮藏菠菜用埋藏法,又称冻藏。在田间向南搭好荫障(或利用阳畦风障),在荫障北侧约15厘米处挖东西向贮藏沟,深约40厘米,宽约80厘米。在11月上旬天气转冷后,把带根收获的菠菜捆成10公斤左右的大把,按两排存入沟内,然后用湿润土将菠菜埋上。根据天气转寒程度逐步加厚覆土。通常从11月到12月底分三次加土,总覆土15—20厘米,使菠菜在整个贮藏期中均处于冻结状态,但菜温不低于—10℃。如果菜温上下波动大,使菜处于冻(?)化状态,很易造成腐烂。当需要取用时,
First, spinach spinach, origin Persia (now Iran), Tang Dynasty into our country, so far 1300 years. Spinach leaf thick soft green, green and green, for the four seasons meal on vegetables. Spinach seasons can be planted, but in the north you need to store autumn spinach to supply the winter market. Buried storage spinach buried method, also known as frozen storage. Take a shade barrier to the south in the field (or make use of the yangling wind barrier) and dig the east-west storage ditch about 15 cm north of the shade, about 40 cm deep and 80 cm wide. After the weather turns cold in early November, put the spinach with root harvest into a bundle of about 10 kilos, deposit it in a ditch in two rows and bury the spinach with moist soil. According to the degree of the weather gradually thicken soil cover. Normally from November to the end of December, soil is added in three portions, covering a total of 15-20 cm so that the spinach is in a frozen state throughout the storage period, but the vegetable temperature is not lower than -10 ° C. If the food temperature fluctuations up and down, so that food in the frozen state, it is easy to cause decay. When you need access,
