Abstract

The invention discloses a seedling culture method of taros. The seedling culture method of taros includes the following steps of 1, seedbed preparation; 2, seed selection; 3, sowing; 4, seedling management, wherein it is needed to properly control fertilizer and water in the seedling stage to prevent the situation that seedlings grow too vigorously and consequently seedling recovering is difficult after field planting, watering is performed once 7-8 days after sowing, and watering is performed only once in the whole seedling stage. By means of the seedling culture method of taros, the yield of taros is increased, crop rotation arrangement is easy, and economic benefits are good.

Description

A kind of method for culturing seedlings of Fructus Colocasiae Esculentae

Technical field

The present invention relates to proportion of crop planting field, particularly the method for culturing seedlings of a kind of Fructus Colocasiae Esculentae。

Background technology

Fructus Colocasiae Esculentae is that Araeceae taro belongs to, and calls taro, taro, taro etc.。China's cultivation history is long, but main in south China, and southwest and the Yangtze river basin are planted, and northeast, northwest are seldom planted。Fructus Colocasiae Esculentae is perennial tuberous plant, often does annual crop cultivation。Dasheen nutrient enriches, and containing substantial amounts of starch, mineral and vitamin, is vegetable, is again grain, can prepared food, drying or powder process。Owing to the starch granules of Fructus Colocasiae Esculentae is little, being only 1/10th of potato starch, its digestibility, up to 98.8, can be made into taro powder and taro mud filling to extend preservation in Fructus Colocasiae Esculentae processing。The Multiple components such as rich in proteins, calcium, phosphorus, ferrum, potassium, magnesium, sodium, carotene, nicotinic acid, vitamin C, vitamin B group, saponin in Fructus Colocasiae Esculentae, in contained mineral, the content of fluorine is higher, the effect have the preventing decayed tooth that cleans the teeth, taking care of one's teeth；Its abundant nutritive value, can strengthen the immunologic function of human body, can as the conventional medicated diet staple food of preventing and treating carcinoma。In cancer operation or postoperation radiotherapy, chemotherapy and rehabilitation course thereof, there is the effect of auxiliary treatment；Fructus Colocasiae Esculentae contains a kind of mucus albumen, can produce immunoglobulin, or claim antibody globulin after being absorbed by the body, the resistance of body can be improved, therefore the traditional Chinese medical science thinks that taro can be detoxified, the carbuncle poison of human body pain is included cancer poison has suppression to clear up effect, can be used to the diseases such as anti-curing oncoma and lymphoid tuberculosis；Fructus Colocasiae Esculentae is basic food, can neutralize the acidic materials of internal accumulation, adjusts the acid-base balance of human body, produces the effect of looks improving and the skin nourishing, pitch-black hair, can also be used with and prevent and treat hyperchlorhydria；Fructus Colocasiae Esculentae contains abundant mucus Saponin and various trace elements, and body can be helped to correct, and that trace element deficiency causes is physically different, simultaneously can appetite stimulator, help digest, therefore the traditional Chinese medical science think that taro can invigorating the spleen and replenishing QI。Fructus Colocasiae Esculentae bulb content of starch is up to 19.5% (accounting for the 59.45% of dry weight), thick protein 2.63%, crude fibre 1.87%, possibly together with multivitamin。In addition Fructus Colocasiae Esculentae bulb is possibly together with a kind of important substance polysaccharide (accounting for 4.9%), and polysaccharide can strengthen the immunologic mechanism of human body and the resistivity to disease, is a kind of heat-clearing and toxic substances removing, spleen invigorating, the health-care vegetable kept fit。

At present, the plantation of Fructus Colocasiae Esculentae is generally adopted live mode, and yield is generally relatively low, and the occupation of land time of Fructus Colocasiae Esculentae is long, does not utilize arrangement crops for rotation, for planting greatly family, deficiency in economic performance。

Summary of the invention

The technical problem to be solved is to provide the method for culturing seedlings of a kind of Fructus Colocasiae Esculentae, improves the yield of Fructus Colocasiae Esculentae, is conducive to crops for rotation arrangement, good in economic efficiency。

For achieving the above object, the method for culturing seedlings of a kind of Fructus Colocasiae Esculentae that the present invention proposes, it comprises the steps:

One, seedbed prepares: select the sandy loam that physical features is low and smooth, soil is more fertile to make seedbed, seedbed width 1m-1.2m, mu executes 2000 kilograms of well-rotted farmyard manures, general calcium 35-50 kilogram, compound fertilizer 20 kilograms, under surface, seedbed, deep 20cm-25cm place adopts base plate compacting, should not loosen, prevent from pricking under root system, during seedling taking, hinder root；

Two, seed selection: select early-maturing variety, such as Huang Heyu, take and have that this varietal characteristic, single plant yield taro higher, sub-and female taro be relatively more neat, kind strain without pest and disease damage, fully ripe, non-sprout tillers growth then, bigger sub-taro is selected to reserve seed for planting again from kind of strain, it is typically in 25-40 gram to be advisable, namely every 500 grams of kind taros are at 12-20, avoid the sub-bud of selection and are hoary hair's, reveal blue or green son and the sub-bud of long handle。Kind taro is tedded 1-2 days, to promote Nutrient Transformation, it is simple to after planting germinating growth after choosing。Also will taro kind by large, medium and small classification when basking seeds, separately sowing。Plant the hair on taro (sheath of remaining) should peel off, be beneficial to the germination that after planting absorbs water。Planting taro after storage is taken out, it is impossible to put for a long time and do not plant, otherwise dehydration is too much, taro skin drying shrinkage。Emerge slowly or affect and germinate。

Three, sowing: local temperature can be sowed higher than 13 DEG C, and Southern Anhui Province area is early and middle ten days in March, plants taro and arranges successively in bed, and terminal bud upwards, is planted and slightly interspaced between taro。Generally pressing the square socket of 5cm one, the fertile fine earth of drained bonnet, drowning kind taro, and water a small amount of water, multiple mulch film is taken arched frame, overlying plastic sheeting, surrounding brick and earth again and is compressed, and in shed, daytime keeps 20-25 DEG C, the highest less than 30 DEG C。Cloudy day and night keep 10-15 DEG C, are not less than 8 DEG C, generally within after planting 15 days, emerge。To throw off mulch film in time, and suitably reduce bed temperature seedling exercising, land for growing field crops can be colonizated in when seedling grows two true leaves。

Four, seedling management: should suitably control rich water during nursery and prevent growth of seedling excessively prosperous, go back Seedling difficulty after field planting。Within after planting 7-8 days, water once, only water once in whole seedling stage。

Example proves, adopts nursery ratio not adopt the Fructus Colocasiae Esculentae yield of nursery to exceed 15%-25%, and per mu yield is up to 1800-2000 kilogram。

The method for culturing seedlings of a kind of Fructus Colocasiae Esculentae proposed by the invention, improves the yield of Fructus Colocasiae Esculentae, is conducive to crops for rotation arrangement, good in economic efficiency。
