Technical field
The present invention relates to Smallantus sonchifolium cultivation method, relate more specifically to a kind of can cultivation and the Smallantus sonchifolium cultivation method that can improve the yield and quality in flat area.
Background technology
Smallantus sonchifolium (smallanthussonchifolius) is also known as chrysanthemum potato, Ya Gong, and being composite family herbaceos perennial, is therophytes in northern China.Originate in South America Andes, fruit is block root, and shape, as sweet potato, is claimed underground fruit.Smallantus sonchifolium is medicinal fruit, containing abundant fructo-oligosaccharide (FOS) and phenolic acid, has anti-oxidant, reducing blood lipid and the anti-effect of grade that treats constipation, and edible safety, effectively, toxic and side effect is little, is particularly suitable for diabetes patient and slimmer is edible.Also the functional components such as selenium and polysaccharide, phenolic acid, flavonoids is rich in yacon leaves.The health care special because of it and medical value, paid attention to more and more widely, food, medical in have broad application prospects.But Smallantus sonchifolium only has artificial cultivation in southern alpine region for a long time, in the north, the Smallantus sonchifolium of especially flat area cultivation exists and yields poorly, the poor quality defects such as especially mouthfeel is poor.
Summary of the invention
For above problem, the object of this invention is to provide a kind of Smallantus sonchifolium kind bud that improves and grow, cultivate full stand strong sprout, improve the cultivation method of the Smallantus sonchifolium yield and quality in North Plain Region cultivation.
Saussurea involucrata fruit branch cultivation method of the present invention comprises the following steps:
Step one, segmentation kind of ball: Smallantus sonchifolium kind ball is carried out vernalization, carry out as the long 2-3cm of bud splitting plant bud, described kind of bud weight is 30-50g;
Step 2, plants bud process: soak 5min with limewash, do seed soaking after drying, and seed soaking solution is obtain in alcohol root-growing agent being dissolved in 50-60%, and the concentration of wherein said seed soaking solution is 2000-5000mg/L, and seed soaking time is 5-8min;
Step 3, nursery: by the kind bud plantation after described step 2 process with nutritive cube, the size of described nutritive cube is 15x13cm; 30 parts of ceramic grains, 40 parts of composite soils and 30 parts of sandy soil are filled successively from top to bottom in described nutritive cube; Described composite soil is 1
:humus soil and the sandy soil of 3 are mixed; Nutritive cube is positioned in greenhouse and cultivates, until during 6-8 sheet leaf, obtain seedling for subsequent use; Described nutritive cube adopts degradation material to make;
Step 4, transplant land for growing field crops, it comprises: wholely, and November the previous year, every mu applies farmyard manure 2000-3000kg, and deep plough 40-60cm afterwards; By land for growing field crops ridging, ridge height 20cm, row spacing 50cm;
Transplanting, is that 40cm carries out field planting according to spacing in the rows, face, ridge is dug kind of a cave plantation, plants the dark 30cm in cave; The seedling band nutritive cube that step 3 obtains is positioned in kind of cave together;
Step 5, field management: watered field planting water the same day in transplanting, described field planting water comprises balsam pear water and the clear water that weight part ratio is 1: 50;
After field planting, impose growth when 40 days fertile, described growth fertilizer is made for clear liquid dung 1000 parts mixes hydrogen-oxygen acid 50 parts, potassium; Fertile 1200 parts every mu of described growth;
Carry out spraying foliage fertilizer September, described foliage fertilizer to be weight ratio be 1: 2: 20 boric acid, sugar alcohol and pure water make.
Preferably, in described step one, described kind of bud at least retains 2 buds.
Preferably, implement in described step one that Smallantus sonchifolium kind ball surface is bright and clean, immaculate and going mouldy.
Preferably, in described step 2, in limewash, the weight ratio of lime and water is 1: 100.
Preferably, in described step 3, hot-house culture temperature is 20-25 DEG C, and incubation time is no less than 25 days.
Preferably, described field management also comprises ridging, in after field planting 90 days, within every 20 days, once earths up, and ridging is highly 10cm.
Preferably, the cultivation method of described Smallantus sonchifolium also comprises: gather, and gathers mid-November, is wiped out by acrial part, after digging out Smallantus sonchifolium, is directly pulverized by acrial part and is embedded in underground by deep ploughing and is passed the winter.
Preferably, the cultivation method of described Smallantus sonchifolium also comprises: in every 3 days of October once, at dusk cover film starting after keeping 10 hours between ridge.
Preferably, the nutritive cube in described step 3 is dixie cup.
Smallantus sonchifolium cultivation method of the present invention, plants bud and processes, and greatly improve kind of a bud rootability, improve kind of a shoot survival percent, can obtain more healthy and stronger seedling is that north Smallantus sonchifolium high yield lays the foundation simultaneously; The Ridged plant when transplanting, for the block root development of Smallantus sonchifolium later stage provides favourable environment; Seedling is planted in land for growing field crops together with nutritive cube, enough temperature and humidities can be provided at seedling early growth initial stage nutritive cube, meanwhile, also can prevent insect pest.There is the field planting water of balsam pear water field planting post-cast strip, and one can prevent insect pest, and carrys out balsam pear water and can reduce soil acidity, is conducive to the root development of Smallantus sonchifolium seedling.By imposing base fertilizer, field planting water and spray the yield and quality that foliage fertilizer both can improve north Smallantus sonchifolium, improves the mouthfeel of north Smallantus sonchifolium.
