Description
Technical field
The invention belongs to forest technical application field, be specifically related to a kind of China fir intelligence fertilization system.
Background technology
China fir, formal name used at school: Cunninghamia lanceolata (Lamb.) Hook., has another name called: Sha Mu, Sha Shu etc., belong to Coniferales, Taxodiaceae arbor, up to 30 meters, the diameter of a cross-section of a tree trunk 1.3 meters above the ground can reach 2.5-3 rice; Bark taupe; Hibernaculum subcircular, male cone is coniform, female cone Dan Sheng, cone oval, long 2.5-5 centimetre, footpath 3-4 centimetre; Seed is flat, is hiding fruit scale, and length is avette or square is circular, April at florescence, cone late October maturation.China fir is tropical trees, likes light.Happiness warm and moist, the climatic environment of foggy quiet wind, not cold-resistant and damp and hot, be afraid of wind, be afraid of drought.Adapt to 15 DEG C ~ 23 DEG C of year-round average temperatures, extreme minimum temperature-17 DEG C, the weather conditions of annual precipitation 800 ~ 2000mm.Low temperature resistance is greater than its drought-resistance ability, and the impact of Water condition is greater than temperature conditions.Be afraid of saline and alkaline, to soil require higher than general species, like fertile, deep, moistening, well-drained acid ground.Shallow root, does not have obvious main root, lateral root, fibrous root prosperity, and regeneration power is strong, but a little less than penetration power.China fir mainly can be used for wind-expelling pain-stopping, loose stasis of blood hemostasis.And building, bridge, shipbuilding, ore pillar etc.
The commerical tree species that China fir is Yangtze River in China basin, the cultivation of Qinling Mountains areas to the south is the widest, growth is fast, economic worth is high.Cultivation area North gets Movement In Southern Qinling Mountains slope, Tongbai in Henan Province mountain, Dabie Mts, anhui, Transition In Jurong, Jiangsu, Yixing, reach Xinyi, Guangdong, Guangxi Yulin, Long John, Guangnan of Yunnan, Malipo, screen limit, Kunming, Huize, Dali in the south, east is from South of Jiangsu Province, Zhejiang, In Western Fujian Province mountain area, to basin, Dadu River, Sichuan (to the east of mill west, Luding area) and west and south Anninghe Watershed.The upper limit of vertical distribution is often variant with the difference of the gentle time condition of landform.At Da Bie Mountain area, east height above sea level, below 700 meters, Yunshan Mountain district is worn below 1000 meters in Fujian, and at Mount Emei, sichuan, China height above sea level, below 1800 meters, Dali height above sea level is below 2500 meters.Also there is distribution in Vietnam.Growth of Chinese Fir is fast, output is high, material is good, purposes is wide, and its timber is building material, the decorative material of high-quality, is also high-quality paper pulp material, is one of most important merchantable timber seeds of China, liked by broad masses.China fir is also one of most important reproducting tree species in Guangxi, extensively cultivates at Gui Bei, northwest, osmanthus, Northeastern Guangxi.Existing lanceolata forest 119.17 ten thousand hm in Guangxi, accumulate 10565.22 ten thousand m
3, being positioned at first of all seeds, China fir is that important effect has been brought into play in Guangxi Development of Forestry Industry and Output Value of Forestry Production increase.Therefore, carry out the research of China fir fine-variety breeding, creation, seed selection excellent Chinese fir kind, the excellent Chinese fir seed that production hereditary quality is high and nursery stock are applied for producing, and have very important realistic meaning.Guangxi is the same with the whole nation has done a large amount of fruitful work on China fir fine-variety breeding is studied, and has selected fine provenance and large quantities of superior families, choiceness are applied to production, and the breeding base of construction is that major contribution has been made in Guangxi forest development.
Along with Cunninghamia Lanceolata Plantations fast development, chinese fir culture is also faced with many problems.If low production forest is than great, China fir woods total quality is not high, and systematism level is not high, and seedling quality awaits further raising, and the mode of production, production technology fall behind, and await constantly bringing forth new ideas, and insect pest preventing and controlling is improper, and seedling quality is poor, not science of field planting time., a lot of local China fir nursery stocks are unsatisfactory, and seedling art is very thin, depauperation, and output and quality are all unstable, illustrate that Growing Seedling of China Fir technology still exists blindness.The happiness of China fir art is wet good fertile, and fertilising is the key factor that affects China fir seedling quality.In southern hills mountain region, due to the poor ridge of soil, add fertilizer practice fall behind, be to cause one of poor major reason of China fir seedling quality.But Fertilizer on Chinese fir the complex nature of the problem, mainly the reasons such as intricate and test period of subjects, edaphic condition, test method, forest management factors is long, China is also very insufficient about the experimental study of Fertilizer on Chinese fir up to now, and some conclusion of Fertilizer on Chinese fir is with obvious provincialism.There is limitation at aspects such as experimental period, test sample number and statistical folding methods in some experimental studies.
Generally speaking, Fertilizer on Chinese fir lacks the guiding of forest land Back ground Information, not land occupation condition and the production potential etc. from self forest land, but indiscriminately imitate other people experience and formulate fertilising scheme, specific aim is not strong, often causes and drops into nutrient excess or Environmental and ecological problems not enough and that cause, still has many unreasonable parts with fertile nutrient structure simultaneously, in actual production, pay attention at present inorganic fertilizer, despise organic fertilizer; Pay attention to the use of a great number of elements, despise the collocation of middle trace element; The balance of paying attention in fertilizer production is joined fertilizer, and the phenomenon such as Balance Absorption of despising standing forest is also commonplace, causes fertilizer efficiency nutrient not high and potential high hidden danger to lack of proper care.Moreover advanced forest fertilization Technique Popularizing means seriously lag behind, the fertilization compositions based on earth measurement that agricultural sector promotes has network, touch-screen, public notification of information, joins the means such as fertile terminal, technology materialization, has obtained good effect.Compared with agricultural sector, the work gap of forestry this respect is still larger, so that advanced practical technology arrival rate is not high, can not get due return.
Summary of the invention
The present invention, in order to overcome the existing problem of above-mentioned chinese fir culture, provides a kind of China fir intelligence fertilization system.
The technical solution adopted in the present invention is:

Described soil testing and fertilizer recommendation technology comprises nutrient formulation, fertilization time and the fertilising consumption of Fertilizer on Chinese fir computation model, Fertilizer on Chinese fir.For example, according to the growth nutrient uptake feature of China fir, before plantation China fir, first soil sample collection is carried out in the forest land of plantation China fir, detect soil nutrient, then carry out reasonable disposition big or middle, trace element according to soil nutrient situation, from plantation by the 3rd, the 4th year, be linked to experts database and fertilizer supply business by the object information of soil nutrient fixed point monitoring, determine element formula, fertilization time and the fertilising consumption of China fir fertilizer.So just ensure that plantation can reach scientic planting China fir, obtained best guidance and realize afforestation high yield.
Described Fertilizer on Chinese fir computation model comprises one or more comprehensive computation models in the reasonable estimation of yield level fertilizer utilization coefficient of the different growth year units of China fir yield potentiality, China fir merchantable timber fertilizer requirement, different growth year fertilizer provision from soil amounts or different growth years.At identical cultivation management, the light of production run, heat, water, gas various places are not quite similar, and residing land occupation condition is also different, and the output finally obtaining is also different.Therefore, reasonably analyzing the productive capacity of China fir, is the key that science is formulated fertilising scheme and raising fertilising quality.Due to different production cycle (period of felling in turn), forest algebraically, different planting density and different regions, final yield result difference is also larger, the disposal route of this China fir intelligence fertilization system is, taking specific central area, 5 year production cycle (period of felling in turn) and mu planting density be as 83 strains are as benchmark, set up production potential and the Different forest stands growth algebraically etc. of different Production Regional, different production cycle, different densities and adjust parameter.And the unit fertilizer requirement of China fir can be by the sample of the sampling to artificial cultivation lanceolata forest, the positions such as point trunk, branch, leaf, bark and the tree root nutrient content of be correlated with is respectively tested, and according to the biomass at each position, calculate respectively the absorption nutrient data of different year and different parts, the merchantable timber yield result obtaining according to test again, obtains specific yield fertilizer requirement.Rationally soil supplying nutrient capability is estimated, it is the important link applying fertilizers scientifically, Growth of Chinese Fir is grown required nutrition and is mainly come from soil supply, and two features of the embodiment main manifestations of soil supply capacity, the one, the supply capacity of yield potentiality and soil nutrient is proportional, be that yield potentiality is larger, soil is can quantity delivered just larger, and vice versa; The 2nd, within the scope of the rational time limit, growth year is longer, and it is larger that soil is supplied with the absolute amount of nutrient.Due to the test findings that Guangxi does not have China fir basis feeder capability to measure at present, be difficult to evaluate the absolute quantity of concrete timbered soil feeder capability, but can be with reference to the test findings of field-crop, can estimate its relative quantity delivered.The fertilizer utilization coefficient of native system mainly refers to chemical fertilizer, and mainly for a great number of elements such as nitrogen phosphorus potassium.The test material of the fertilization effect to 32 of distribution various places processing.To the test findings having obtained, by the estimation result of above-mentioned specific yield fertilizer requirement, yield potentiality, relative soil nutrient supply capacity method for parameter estimation, calculate respectively the fertilizer utilization coefficient of each processing, and result of calculation is analyzed by box construction method, rejecting abnormalities value, point growth year is sorted out statistics.After the evaluation method of above-mentioned forest land yield potentiality, specific yield fertilizer requirement, soil supplying nutrient capability and fertilizer utilization coefficient is set up, can be according to the actual conditions of the land occupation condition about forest land, soil nutrient situation, cultivation production factors etc., obtain the occurrence of relevant parameters, and according to obtaining for balance fertilizing computing formula, the formula of its calculating is:
Rate of fertilizer application=(estimated output institute fertilizer requirement-fertilizer provision from soil amount) ÷ utilization rate of fertilizer
Wherein: estimated output institute fertilizer requirement=estimated output × specific yield fertilizer requirement
Soil is for nitrogen amount=soil supply rate * yield potentiality * specific yield nitrogen requirement
Nitrogenous fertilizer usage factor=10.16/10*57.64=58.56%
Nitrogen fertilizer application amount=(33.34-15.87)/0.5856=29.83 (kg/ mu)
