Description
Technical field
The present invention relates to agricultural technology field, be specifically related to the implantation methods of a kind of rich selenium water spinach.
Background technology
Water spinach (Ipomoeaaquatica), original name harmony dish, has another name called, and rattan vine vegetable, water spinach, lush dish, logical heart dish, is not in the mood for dish, urn dish, empty cylinder dish, bengal dayflower herb, is the annual or perennial herbaceous plant that overgrows of Convolvulaceae.Originate in China tropical rainy area, suitable growth, at sough, is mainly distributed in Lingnan area, is the green vegetable that southern china is generally cultivated summer and autumn.It opens white horn-like flower, because its stalk center is empty, therefore claims " water spinach ".
The Leaf-feeding insects of water spinach is the tender cauline leaf of children, can stir-fry and eat or cold and dressed with sauce, cooks soup dish equivalent " spinach ".It is nutritious, and 100 grams of water spinach calcics 147 milligrams, occupy leaf vegetables first place, vitamin A exceeds 4 times than tomato, and vitamin C exceeds 17.5% than tomato.Water spinach is long for picking time, is the leaf vegetables of growth in summer, can break the structure of the north few leaf vegetables many fruits pod dish in summer, not by the restriction of high temperature, heavy rain, thus also carry out introducing and planting in the north, and obtain successfully.
Heart dish Root Distribution is shallow, and be the system of fibrous root, regeneration capacity is strong.Stem is overgrow, circular and hollow, soft, green or lavender, thick 1 ~ 2 centimetre of stem.Stem has joint, often saves except axillalry bud, also can grow adventive root, and internode length is 3.5 ~ 5 centimetres, and the longest reaches 7 centimetres.Cotyledon to life, the shape of a hoof.True leaf alternate, blade face is smooth, Quan Yuan, pole tip, and vein is netted, and middle veinclearing shows projection, and leaf is lanceolar, long oval or heart-shaped.Leaf is wide 8 ~ 10 centimetres, and the widest reaches 14 centimetres, and leaf is long 13 ~ 17 centimetres, the longlyest reaches 22 centimetres.Petiole is longer, is about 12 ~ 15 centimetres, and most elder is 17 centimetres.Hollow is spill, and fruit is capsule, and subcircular, seed pitchy, dry granular weighs 32 ~ 37 grams.Water spinach is with seed or tender stem breeding, and the north is with seminal propagation.
Water spinach property happiness high temperature and humidity environment.Seed germination needs more than 15 DEG C; The kind rattan axillary bud sprouting initial stage must remain on more than 30 DEG C, and sprouting like this could be neat rapidly; Cissoid growth thermophilic is 25 ~ 30 DEG C, and temperature is higher, and cissoid growth is vigorous, and the plucking intervals time is shorter.Water spinach ability 35 ~ 40 DEG C of high temperature; Less than 15 DEG C cissoid poor growths; The growth of less than 10 DEG C cissoids stops, not resistance to frost, meets white cauline leaf and withered.Kind of rattan is stored sth. in a cellar temperature and should remain on 10 ~ 15 DEG C, and has higher humidity, not so plants rattan and easily to freeze to death or dried-up.
