Description
Technical field
The invention belongs to Herba Spirodelae technical field in farmland, is removed, a kind of method for refering in particular to Herba Spirodelae is removed in Corm Eleocharitiss field.
Background technology
Usually said Herba Spirodelae includes the blue or green duckweed of Lemnaceae (belonging to Angiospermae Monocotyledonae), duckweed, Man Jiang
The Herba azollae imbricatae of red section's (belonging to Pteridophyta), Japanese pagodatree leaf of Japanese pagodatree leaf section (belonging to Pteridophyta) etc..Herba Spirodelae and duckweed with
Bud is bred, and Japanese pagodatree leaf and Herba azollae imbricatae carry out sporogenesis or nourish and generate.These " special " weeds often mix generation, and growing way is numerous
Cyclopentadienyl, forms the floating colony of the water surface that gathers, is agglomerated into clump, cover the water surface, and it is low to lack light, anoxia, temperature in causing water, has a strong impact on work
Thing normal growth is developed.Therefore, peasant is very urgent for the hope that Herba Spirodelae is removed in farmland.
Corm Eleocharitiss (Eleocharis tuberosa) belong to Cyperaceae Eleocharis perennial root shallow water herbaceous plant, ancient to claim Chinese herbaceous peony, another name
Horse hoof, Di Li, black taro, an ancient name for water chestnut etc., using its underground bulb as edible organs, existing 3000 or so cultivation histories so far.Water chestnut
Shepherd's purse color of the leather purple is black, and meat is pure white, taste is fresh and sweet succulence, the crisp tasty and refreshing slag that disappears, and has the good reputation of " underground pear " from ancient times, and northerner regards it
For " south of the River Radix Ginseng ".Corm Eleocharitiss can not only be used for fruit, but also as vegetable, be the industrial crops of fruit and vegerable dual-purpose type, and Water Chestnuts are about
Containing carbohydrate 21.8%, protein 1.5%, fat 0.1%, crude fibre 0.6%, with abundant nutrition and health care valency
The effects such as value, also heat clearing away, transforming phlegm and dispersing accumulations, diuresis, blood pressure lowering, cancer-resisting, its extract has to antibacterial, yeast and mycete
Act on compared with high inhibition, be preferable health food, starch, canned food, maltose etc. can be processed into, can also make liquor-making raw material, after processing
Waste residue can be used as feedstuff.
Corm Eleocharitiss growth adaptability is stronger, originates in southern china and India.Abroad, Corm Eleocharitiss main wild is distributed in the southeast
The low lying areas such as the national pond such as Asia, America, Europe and Oceania, beach；In China, in addition to extremely frigid zones, its distribution is several
Throughout national each provinces and regions, and Economical cultivation is then mainly in the Yangtze river basin and its areas to the south.Ye Jingyuan (2001) researchs are sent out
Existing, not only domesticating and cultivating is more early for two province of Jiangsu and Zhejiang Provinces, compares Sheng, and quality is also relatively good, therefore speculates Jiangsu and Zhejiang Provinces one with possibly
The centre of origin of Chinese domesticating and cultivating Corm Eleocharitiss.At present, Corm Eleocharitiss cultivation has defined several famous producing regions, such as Guilin, Zhejiang
Jiang Yuhang, Jiangsu Gaoyou and Suzhou, Fujian Foochow, Hubei Xiaogan, Tuanfeng County and Shayang County, willow township of Lujiang, Anhui county and Xuan Zhou etc..
At present, quickly, area and yield all increase the production development of China Corm Eleocharitiss year by year.According to incompletely statistics, China is existing
About more than 50 ten thousand mu of Corm Eleocharitiss cultivated area, 800,000 tons or so of gross annual output amount, mainly for domestic market is answered, partly for processing, are made
Into canned food, starch, Corm Eleocharitiss jelly, Corm Eleocharitiss dew, preserve etc., at home and abroad market is in very great demand for product.The canned water chestnut of China
Occupy an important position in the international market. European and American countries and Hongkong and Macro, southeast asian market are sold within wherein 2003 up to 8.5 ten thousand tons,
It is Water chestnuts exporting country the biggest in the world.In recent years, with the adjustment of agricultural planting industry structure, the cultivated area of Corm Eleocharitiss and
Yield is continuously increased, but yield per unit area then has downward trend year by year.Why Corm Eleocharitiss production occurs " two high (cultivations
Training area increase, total output increase) one low (yield per unit area decline) " and phenomenon, main cause is that traditional cultivation kind is old
Change, plant sexual involution, introducing a fine variety not science, cultivation technique and the reason such as do not match, cause that Corm Eleocharitiss pest and disease damage is serious, resistance is poor, yield poorly,
Poor quality, commodity rate are low.Have a strong impact on the further sound development of Corm Eleocharitiss industry.
There is the impact to Corm Eleocharitiss growth in Herba Spirodelae：Herba Spirodelae will be doubled and redoubled, will soon be paved with the water surface once existing,
Tanaka's fertilizer is absorbed, keep the sun off irradiation, make water body muddy, field water temperature is low, also resulted in large amount of organic and chemistry occurs instead
Should, increase toxic bacteria, water rate of oxygen reduce, affect ventilation toxin expelling, affect farming, be unfavorable for the growth of Corm Eleocharitiss.
The method for generally removing Herba Spirodelae：At present, the method for generally removing Herba Spirodelae has salvaging, applies herbicide, put water in field, support
Grow Ctenopharyngodon idellus etc..Herba Spirodelae cost of labor is salvaged greatly in Corm Eleocharitiss field, and peasant is not easily accepted by；Apply herbicide dangerous, it is also little on the market
There is the safety herbicide for Corm Eleocharitiss；Water in field is put because speed is fast, Herba Spirodelae is easy to stick in stalk, in ridge thick grass, on native table, in stem
Herba Spirodelae on stalk, in ridge thick grass is difficult extremely, easily survives after rehydration, survives rear meeting amount reproduction again, does not reach Herba Spirodelae
Purpose, furthermore the meeting waste water resource that discharges water without reason.Good using the removing Herba Spirodelae method such as cultivation Ctenopharyngodon idellus, unfortunate Corm Eleocharitiss pest and disease damage is tight
Weight, prevents and treats often, operating difficultiess, in practice it has proved that Corm Eleocharitiss field should not cultivate Ctenopharyngodon idellus.
