A kind of yacon cultural method
Technical field
The present invention relates to yacon cultural methods, and relating more specifically to one kind can cultivate in plains region and production can be improved
The yacon cultural method of amount and quality.
Background technique
Yacon (smallanthus sonchifolius) is also known as chrysanthemum potato, Ya Gong, is composite family herbaceos perennial,
Northern China is annual plant.South America Andes is originated in, fruit is root tuber, and shape such as sweet potato is claimed underground fruit.
Yacon is medicinal fruit, oligofructose rich in and phenolic acid, has anti-oxidant, reducing blood lipid and anti-is treated constipation
Effect, and edible safety, effectively, toxic side effect it is small, it is edible to be particularly suitable for diabetes patient and slimmer.It is also rich in yacon leaves
Containing the functional components such as selenium and polysaccharide, phenolic acid, flavonoids.Because of its special healthcare function and medical value, increasingly obtain wide
General attention has broad application prospects in terms of food, medicine.But yacon is for a long time only in southern alpine region
There is artificial cultivation, in the north, the yacon of especially plains region cultivation is there are low output, and poor quality especially mouthfeel is poor etc.
Defect.
Summary of the invention
In view of the above problems, cultivating full stand strong sprout the object of the present invention is to provide a kind of development of raising yacon seed bud, mentioning
The cultural method for the yacon yield and quality that height is cultivated in North Plain Region.
Saussurea involucrata fruit branch cultural method of the present invention includes the following steps:
Step 1 divides bulb:Yacon bulb is subjected to vernalization, is split to obtain seed bud as the long 2-3cm of bud, it is described
Seed bud weight is 30-50g;
Step 2, seed bud processing:5min is impregnated with limewash, seed soaking is done after drying, seed soaking solution is that will take root
Agent is dissolved in the alcohol of 50-60% and obtains, wherein the concentration of the seed soaking solution is 2000-5000mg/L, seed soaking time is
5-8min;
Step 3, nursery:By the plantation of the step 2 treated seed bud with nutritive cube, the size of the nutritive cube is
15x13cm;30 parts of ceramic grains, 40 parts of composite soils and 30 parts of sandy soil are sequentially filled in the nutritive cube from top to bottom;It is described mixed
Closing soil is 1∶3 fertile soil and sandy soil is mixed;Nutritive cube is placed in greenhouse and is cultivated, until seedling is obtained when 6-8 piece leaf
It is spare;The nutritive cube is made of degradation material;
Step 4 transplants crop field comprising:Site preparation applies farmyard manure 2000-3000kg November the previous year per acre,
Deep plough 40-60cm later;By crop field ridging, the high 20cm in ridge, row spacing 50cm;
Transplanting is that 40cm is colonized according to spacing in the rows, plants in the ridge face cave Shang Wazhong, plant cave depth 30cm;Step 3 is obtained
The seedling band nutritive cube obtained is placed in together in kind of cave;
Step 5, field management:Planting water was poured in the transplanting same day, the planting water includes the balsam pear that weight part ratio is 1: 50
Water and clear water;
Growth fertilizer is imposed at 40 days after field planting, the growth fertilizer is that 1000 parts of cleaning up excrement water, 50 parts of potassium of mixing hydrogen-oxygen acid is made
At;Described 1200 parts per acre of growth fertilizer;
Spray foliar fertilizer in September part, the foliar fertilizer be weight ratio be 1: 2: 20 boric acid, sugar alcohol and pure
Water is made.
Preferably, 2 buds are at least retained in the step 1, in the seed bud.
Preferably, implement yacon kind ball surface in the step 1 and want bright and clean, immaculate and mildew.
Preferably, in the step 2, the weight ratio of lime and water is 1: 100 in limewash.
Preferably, in the step 3, hot-house culture temperature is 20-25 DEG C, and incubation time is no less than 25 days.
Preferably, the field management further includes ridging, in after field planting 90 days, is once earthed up within every 20 days,
Ridging height is 10cm.
Preferably, the cultural method of the yacon further includes:Harvesting, is harvested mid-November, by overground part
Sub-cut removes, and after digging out yacon, aerial part is directly crushed and is embedded in underground by deep ploughing and passed the winter.
Preferably, the cultural method of the yacon further includes:It is primary every 3 days of October, it is covered between ridge in the dusk
Lid film simultaneously starts after holding 10 hours.
Preferably, the nutritive cube in the step 3 is dixie cup.
Yacon cultural method of the present invention, seed bud are handled, and seed bud rootability is greatly improved, and improve seedling
Survival rate, while can obtain more healthy and stronger seedling is that north yacon high yield lays the foundation;The ridging kind in transplanting
It plants, provides advantageous environment for the development of yacon later period root tuber;Seedling and nutritive cube are planted together in crop field, in seedling early growth
Initial stage nutritive cube can provide enough temperature and humidities, it is also possible to prevent insect pest.There is determining for balsam pear water in field planting post-cast strip
Water is planted, one can prevent insect pest, and soil acidity can be reduced by carrying out balsam pear water, be conducive to the root development of yacon seedling.
It by imposing base fertilizer, planting water and sprays foliar fertilizer both the yield and quality of north yacon can be improved, improve north
The mouthfeel of side's plantation yacon.
