Description

A kind of efficient cultivation method of balloonflower root
Technical field
The present invention relates to agricultural plantation technology field, specifically, relate to a kind of efficient cultivation method of balloonflower root.
Background technology
Balloonflower root, another name burden flower, small bell flower, mitral flower, can do ornamental flower.Its root can be used as medicine, and has cough-relieving apophlegmatic, effect such as a surname lung, apocenosis etc., traditional Chinese medical science common medicine.Tender leaf can pickle into salted vegetables, and in Yanbian of China, balloonflower root is very famous pickles food materials.At present, the breeding of balloonflower root normally adopts seminal propagation, and seed propagation method is made up of following steps: 1. reserve seed for planting, choose seeds, and will carry out germination test before plantation, ensures that percentage of seedgermination is more than 70%.2. sow, balloonflower root can be sowed in spring also can summer sowing.Spring sowing first will scald seed soaking by temperature, be placed in warm water by seed, be stirred to immediately water cool after, then soak 8 hours, the seed place of wet cloth bag, builds with the wet piece of sack, morning and evening every day with warm water washing once, about 5 days, can sow when Seed sprouting.Broadcast and be evenly sowed in ditch by seed, because seed is tiny, sowing time can be sowed with after fine sand and seed mixing, and broadcasting rear blinding or fire ash, will water after broadcasting moisturizing in arid area.Every mu of sowing quantity 500-750 gram.Will note between the seeding stage weeding with a hoe, carry out thinning, stay strong sprout by spacing rice when height of seedling about 2 centimetres, the rare or disconnected excellent place of seedling should be brought in the cloudy day and be filled the gaps with seedlings.After execute rare people and animals' liquid dung, execute on bonnet, then impose once and earth up, prevent lodging.Execute on bonnet.In addition, also will often weed with a hoe, sky early will water in time.Generally gather in the crops before broadcasting rear autumn Mo or rudiment in early spring.Prevent balloonflower root benefit root balloonflower root with straight strip, solid, trouble root is good less.The balloonflower root of cultivation often has many conjunction roots, has the also tridentate of y-bend, and some main root tubbiness are less than, side root.If greatly affect the many seedlings of quality one strain just have trouble root, the growth of the more luxuriant main root of seedling is just more affected.Otherwise strain one seedling is then without trouble root, supporting root.See that to solve balloonflower root trouble root problem very simple.As long as strain one seedling accomplished by the balloonflower root of cultivation, then without trouble root, supporting root.Therefore, the unnecessary symptom of a trend should be rejected at any time, the most easily occur many seedlings when especially within the 2nd year, the spring turns green, now will pay special attention to, the unnecessary symptom of a trend is removed, keep strain one seedling.Execute phosphate fertilizer, Shaoshi helium potash fertilizer, prevents acrial part excessive growth, pinches if desired more simultaneously, reduces nutrient consumption, impels the normal growth of root.
The dry seed broadcast needs to emerge for about 25 days, and the seed of vernalization sowing also needs to emerge for about 10 days.After seedling is unearthed, remove weeds in time, seedling is overstocked wants in good time seedling thinning, is advisable with every 100 square centimeter of 10 strain-12 strain, and 5 centimetres, interval retains a strain and carries out thinning (about every mu of 60,000 strains), and cooperation is loosened the soil.Later stage also will carry out weeding in good time.The balloonflower root florescence is longer in addition, consume a large amount of nutrient, affect root growth, wants timely flower and fruit thinning to improve the seed output and quality of root except seed field.The weak point of seed propagation method be its complex steps and the cycle longer.Balloonflower root can be bred by cuttage, but due to balloonflower root be perennial root draft, property happiness low humidity is dry, adopts common cottage method easily to infect damage by disease and insect and rooting rate is low, so use less.
Summary of the invention
In view of this, the object of this invention is to provide a kind of efficient cultivation method of balloonflower root, with solve adopt common cottage method to cultivate time, nursery stock easily infect damage by disease and insect and rooting rate low and exist deficiency.
The present invention solves the problems of the technologies described above by the following technical programs:
An efficient cultivation method for balloonflower root, comprises the following steps:
(1) cuttage and seedling culture: in 2-3 month in spring, growth selection is healthy and strong and without the high-quality balloonflower root maternal plant of damage by disease and insect, the cutting wholeheartedly of 4-6 leaf is intercepted from maternal plant with sterilization cutter, then cutting is stained with mud slurry after again by its cuttage in seedling culture hole plate, the matrix of cave dish is that 1.5-2:1 is formulated by peat and perlite in mass ratio, then adopts conventional seedbed system method to manage;
(2) wholely: before balloonflower root seedling replanting, first deep plough planting site 35-40cm, and every mu of organic fertilizer 2500kg, potash fertilizer 30-40kg, urea 30-35kg, phosphate fertilizer 40-45kg, be evenly spread on above-mentioned fertilizer in ground;
(3) transplant: after the cuttage seeding in step (1) is cultivated 20-25 days, transplanted in the planting site in step (2) after process, control spacing is 15-20cm, and line-spacing is 20-25cm, and mu plants 3.2-3.5 strain;
(4) final-period management: a. weeding: start weeding when seedling grows to 9cm, every other month except once careless; B. apply fertilizer: topdress when seedling grows to 15-20cm once, application of organic fertilizers and phosphate fertilizer, wherein, Rate of Organic Fertilizer is 3000kg/ mu, and Phosphorus Fertilizer Rates is 40kg/ mu; C. pinch, except flower: after height of seedling 10cm, top bud will be extractd in time, and spray ethene except flower at full-bloom stage; D. diseases and pests controlling: when finding damage by disease and insect, 0.5:0.5:100 bordeaux mixture is sprayed to region of disease;
(5) gather: transplanting autumn then, prescinded by balloonflower root ground cauline leaf, dug underground rhizome, removing fibrous root, scrapes off tertia and washes rear 3-4h under water, and then drying.
Described mud is that the tpn of 800-1000 times of liquid and the root-inducing powder mixed preparing of 60-80PPm form.
In described step (3), when cuttage seeding being transplanted, remove plantation in the lump together with matrix.
Beneficial effect of the present invention is, the present invention adopt cuttage and seedling culture, whole, transplant and the series of processing steps such as final-period management, and by raw material used in each step and the strict control of various parameter values that relates to, improve the rooting rate of cutting, the transplanting survival rate of seedling, substantially reduce the cultivation time of balloonflower root, and add the output of balloonflower root.Meanwhile, method of the present invention is simple, and production cost is lower.
