Description
Technical field
The present invention relates to a kind of notoginseng soil improvement methods, belong to Chinese medicine planting technology field.
Background technique
Continuous cropping obstacle refers to the continuously crop growth caused by same culturing on soil same origin or nearly edge crop
It is abnormal.Symptom is generally retarded growth, yield, quality decline, and under extreme case, local dead seedling does not send out seedling or hair seedling not
It is prosperous;Brown stain occurs for most aggrieved root systems of plant, branch is reduced, and vigor is low, and distribution is narrow, causes to absorb moisture, nutrient
Ability decline.
Radix Notoginseng (Panax notoginseng (Burk.) F.H.Chen) is perennial herb plant, is that Yunnan is white
The primary raw material of the big kind of the China such as medicine, compound danshen dripping pills, Pien Tze Huang, " Xuesaitong Injection " Chinese patent drug is the one of cloud medicine industry development
Big pillar industry plays a significant role promotion this area socio-economic development.Current wild Radix Notoginseng is very rare, and existing three
Seven be artificial cultivation.Due to large area single cropping year after year, Radix Notoginseng belongs to the perennial plant for covering cultivation in addition, and likes temperature
Warm current is wet, thus cause its ecological environment of soil deteriorate, Soil-sickness Problem is serious, and continuous cropping obstacle be restrict Radix Notoginseng yield and
The important bottleneck of quality-improving.
The method of improvement notoginseng soil is mainly fumigated by chemicals to realize at present, and the period is longer, and mistake
Degree application chemicals can bring a series of negative effect such as environmental pollution, or even endanger human health.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of notoginseng soil improvement method.
This method increases Soil ventilation water penetration by the mixture of application weathered coal and rice husk, and weathered coal is made through oxidation in the soil
With humic acid is formed, the formation of soil aggregate structure can be promoted, make the reduction of its bulk density, porosity increases, to have good
Permeability, and humic acid has facilitation to the activity of Soil Microorganism, can make aerophile bacterium in soil, actinomyces,
The quantity of cellulose-decomposing bacteria increases, and is conducive to the mineralising for accelerating organic matter, promotes the release of nutrient, mention for edaphon
It is provided with function source, improves rhizosphere environment, stimulates soil enzyme activities in various degree, be more advantageous to suction of the Radix Notoginseng to nutrient in soil
It receives and utilizes, improve utilization rate of fertilizer, reduce Radix Notoginseng production cost, preferably serve Chinese medicine field of planting.This method is logical
Cross following technical scheme realization.
A kind of notoginseng soil improvement method, comprising the following steps:
Step 1, land clearance: after Radix Notoginseng harvest, plant residual on ridge (Radix Notoginseng stalk, fallen leaves) and covering are removed;
Step 2 applies mixture: during weathered coal and rice husk mixture be manured into soil after step 1 cleaning, being turned over machinery
It ploughs, is evenly distributed on mixture in ridge in soil, wherein the amount of weathered coal and rice husk is 1400 ~ 2000kg of soil per acre, wind
Change coal and rice husk mixed proportion is 1:1 ~ 1:1.5;
Step 3, irrigation water management: it periodically pours water Radix Notoginseng ridge after step 2 applies mixture, makes soil water content 60
~ 80%, irrigation water management 30 ~ 40 days;
Step 4, plantation and management: coating, Radix Notoginseng emergence are transplanted in the ridge handled through step 1 to 3 and are laid with to Radix Notoginseng seedling
Excessive humic acid, holding soil pH are 5.7 ~ 6.6 in preceding sprinkling sodium chloride solution and in soil, then carry out daily conventional field
Between management until three medium wells.
It is to pour water within every 6 ~ 7 days once to the irrigation frequency that Radix Notoginseng ridge is poured water in the step 3.
The concentration of sodium chloride solution is ‰ ~ 40wt of 30wt ‰.
The beneficial effects of the present invention are:
(1) weathered coal raw coal powder is resourceful, cheap, and processing technology is simple;
(2) humic acid can promote soil aggregate structure to be formed, and be conducive to the adjusting of water in soil, air and heat;
(3) soil nutrient supply situation can be improved, improve Radix Notoginseng root activity, promote to grow and improve yield;
(4) quantity of aerophile bacterium in soil, actinomyces, cellulose-decomposing bacteria can be made to increase, be conducive to the mine for accelerating organic matter
Change, promote the release of nutrient, is provided with function source for edaphon, improves rhizosphere environment, promote edaphon
And enzymatic activity;
(5) humic acid can make it is some in the form of difficulty soluble salt existing for microelement such as Fe, Al, Cu, Mg, Zn etc. form complex compound
And it is dissolved in water and is absorbed by plants;
(6) it is compared with the traditional method, the utilization rate of fertilizer can be promoted by generating humic acid by application weathered coal, promote Radix Notoginseng raw
It is long, increase soil with organic matter content, improve crop quality, greatly reduce the usage amount of agriculture chemical, promotes agricultural production
While, reduce the pollution to ecological environment.
