Description
Technical field
The present invention relates to the fertilizing method in Chinese medicine cultivation field, more particularly to a kind of plantation of bletilla striata.
Background technology
The bletilla striata is orchid family herbaceos perennial, and the high 18~60cm of plant, pseudobulb of coming into being is grown into certain for spheroidal
The block pseudobulb of degree formation V-shaped, 4~May of florescence, 7~September of fruiting period.
The bletilla striata is liked at warm, dark and damp environment, such as wild mountain valley sylvan life.Slightly resist cold, In Middle And Lower Reaches of Changjiang River can open country cultivation
Training.Shade tolerance is strong, avoids strong light direct beam, blade is easily withered and yellow during summer hot and dry weather.The good husky earth containing more than humus of suitable draining
Soil, is frequently grown in the relatively cliff of moistening, liver moss layer, is often combined with shrub, or be grown on border, thick grass, have mountain spring
Place, is also born under the evergreen broadleaf forest of 100~3200 meters of height above sea level, a woods or coniferous forest.
The stem tuber of the bletilla striata is as Chinese medicine, and with very high medical value and economic value, wild bletilla striata is far from satisfaction
Market needs, and artificial cultivation is the main channel of bletilla striata industry sustainable development.Bletilla striata crop cycle is longer, general plantation the 3rd
Year could harvest, and medicinal material market fluctuation is larger, causes prospective earnings risk larger.Existing bletilla striata cultivation technique imperfection,
Technology without specification in terms of field management technology such as fertilising, causes the yield and Quality Down of bletilla striata stem tuber.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of bletilla striata plantation for improving bletilla striata Tuber yields and quality
Fertilizing method.
The present invention is to solve above-mentioned technical problem by the following technical programs:The fertilizing method of bletilla striata plantation, including with
Lower step:Urea, calcium superphosphate, potassium sulfate, ammonium molybdate are applied into plantation soil as base manure first when the bletilla striata plants preplanting treatment
In earth, urea, potassium sulfate, zinc sulfate, borax are then applied when topdressing in bletilla striata growth period, topdress several times application, base
The fertilizer and consumption of various fertilizer is every mu of 55~65kg of urea, 60~70kg of calcium superphosphate, 18~22kg of potassium sulfate, boron in topdressing
2.5~3.5kg of sand, 2.5~3.5kg of zinc sulfate, 0.25~0.35kg of ammonium molybdate.
As the technical scheme of optimization, the fertilizer amount in base manure is every mu of 10~12kg of urea, calcium superphosphate 60~
70kg, 3~4kg of potassium sulfate, 0.25~0.35kg of ammonium molybdate.
As the technical scheme of optimization, bletilla striata growth period is topdressed three times every year, carries out annual March to April chasing after for the first time
Fertilizer, May to June is topdressed for the second time, and August to September carries out third time and topdressed, and altogether topdress for nine times within 3 years.According to the bletilla striata
The growth cycle arrangement plan of topdressing, its yield and quality is improved.
As the technical scheme of optimization, 4~5kg of urea, 1.3~1.5kg of potassium sulfate are applied for every mu when topdressing for the first time every year,
0.9~1.1kg of zinc sulfate, 0.9~1.1kg of borax;8~9kg of urea, 2.5~3kg of potassium sulfate are applied when topdressing for the second time for every mu;
The fertilizer amount that third time is topdressed applies 3~4kg of urea, 1.2~1.4kg of potassium sulfate for every mu.
As the technical scheme of optimization, the nutrient situation of the plantation soil is:The topsoil soils content of organic matter be 30~
50g/kg, available nitrogen 0.04g/kg~0.1g/kg, rapid available phosphorus 0.005g/kg~0.02g/kg, available potassium 0.02g/kg~
0.15g/kg, pH are 5~7.The nutrient situation for planting soil is adapted to bletilla striata growth, and the fertilising of the bletilla striata is formulated according to its nutrient situation
Scheme.
Experiment sets different nitrogenous fertilizer, phosphate fertilizer, K Amounts to analyze it to bletilla striata stem tuber polysaccharide and protein content
Influence, bletilla striata kind is the trident bletilla striata, and nitrogenous fertilizer uses urea, is 46% containing N, phosphate fertilizer uses calcium superphosphate, containing P2O5For
16%, potash fertilizer uses potassium sulfate, containing K2O is 33%, and whole phosphate fertilizer, 40% nitrogenous fertilizer and 40% potash fertilizer are applied as base manure
Enter, applied during 60% nitrogenous fertilizer and 60% potash fertilizer are topdressed at each time of bletilla striata growth period, each scheme is repeated 3 times, totally 30
Individual cell, each plot area is 6m2, the line-spacing of the plantation bletilla striata is 30cm, and spacing in the rows is 15cm.
The influence of table 1 different nitrogenous fertilizer, phosphate fertilizer, K Amounts to bletilla striata stem tuber polysaccharide and protein content.
It can be drawn by table 1:Phosphate fertilizer is the most notable to the effect for improving bletilla striata stem tuber polyoses content, next to that nitrogenous fertilizer, most
After be potash fertilizer, fertilizer applications 3,5,6,9 all significantly improve the polyoses content of bletilla striata stem tuber;Potash fertilizer is to improving bletilla striata stem tuber albumen
The effect of matter content is the most notable, next to that phosphate fertilizer, is finally nitrogenous fertilizer, fertilizer applications 1,5,6,9 all significantly improve bletilla striata block
The protein content of stem.
The influence of table 2 different nitrogenous fertilizer, phosphate fertilizer, K Amounts to bletilla striata Tuber yields.

It can be drawn by table 2:Nitrogenous fertilizer is the most notable to the effect for improving bletilla striata Tuber yields, next to that phosphate fertilizer, is finally
Potash fertilizer, fertilizer applications 2,4,5,6 all significantly improve the yield of bletilla striata stem tuber.
Comprehensive analysis, chooses bletilla striata Tuber yields highest and significantly improves applying for bletilla striata stem tuber polysaccharide and protein content
Fertile scheme 6, i.e., every mu is applied urea 60kg, calcium superphosphate 65kg, potassium sulfate 20kg.
In bletilla striata growth course in addition to needing Rational Application nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, also need suitably increase zinc fertilizer, boron fertilizer,
Molydbenum fertilizer.Zinc can promote photosynthesis, be also the constituent of a variety of enzymes, participate in the division of cell and the synthesis of protein;Boron energy
Promote the transport of sugar;Molybdenum participates in the metabolism and assimilation of nitrogen, promotes the transfer of photosynthesis and carbohydrate, can improve chlorophyll
Content and stability.These trace elements are the indispensable elements of plant growth, but excessive concentration also can produce murder by poisoning to plant.
Experiment sets different zinc fertilizers, boron fertilizer, the amount of application of molydbenum fertilizer to analyze its influence to bletilla striata stem tuber polyoses content,
Bletilla striata kind is the trident bletilla striata, and zinc fertilizer uses zinc sulfate, and boron fertilizer used borax, and molydbenum fertilizer uses ammonium molybdate, regard molydbenum fertilizer as base
Fertilizer is applied jointly with nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, with nitrogenous fertilizer, potash fertilizer during zinc fertilizer and boron fertilizer are topdressed at each time of bletilla striata growth period
Common to apply, each scheme is repeated 3 times, totally 30 cells, and each plot area is 6m2, the line-spacing of the plantation bletilla striata is 30cm, and spacing in the rows is
15cm。
The influence of table 3 different zinc fertilizers, boron fertilizer, molydbenum fertilizer amount of application to bletilla striata stem tuber polyoses content.
Fertilizer applications | Zinc sulfate (kg/ mus) | Borax (kg/ mus) | Ammonium molybdate (kg/ mus) | Polyoses content |
1 | 3 | 3 | 0.3 | 37.71% |
2 | 3 | 1.5 | 0.15 | 33.57% |
