Abstract
The invention provides a nutrition medium for raising towel gourd seedlings. The nutrition medium is characterized by comprising one or more of the following components in parts by volume: 25-35 parts of coconut shell, 10-15 parts of vermiculite and 5-10 parts of perlite. The composite medium is suitable for raising the towel gourd seedlings. Compared with conventional seedling raising, the nutrition medium is capable of promoting growth of the seedlings; physiological indexes such as sound seedling index, root activity and net photosynthesis are higher than those of conventional seedling raising. Furthermore, the nutrition medium is safe and free from pollution, has the advantages of saving resources, lowering the production cost and effectively improving the seedling raising quality and efficiency and the like, and is beneficial to promoting the cost-saving, efficient and sustainable development of industrial seedling raising.
Description
Technical field
The invention belongs to field of plant growing technology, be specifically related to a kind of sponge gourd grow seedling nutritional matrix.
Background technology
Sponge gourd nursery requires that Nutrition Soil is fertile, and the physicochemical property of Nutrition Soil is good, and water retention capacity is strong, and the content of organic matter is high, and permeability is good.Existing sponge gourd nursery mainly more adopts the peat composed of rotten mosses, vermiculite, perlite with certain proportioning or single use, but China's peat composed of rotten mosses skewness, current China peat composed of rotten mosses is mainly distributed in northeast, trans-regional use causes cost up, the peat composed of rotten mosses is non-renewable resources, a large amount of exploitations has certain influence to ecotope, and various places are all in the problem that positive research and development new matrix solution cost of transportation height and the peat composed of rotten mosses are developed in a large number.Each research institute, colleges and universities, agribusiness's active adoption mushroom slag, ash, coconut husk, rice chaff, stalk, Chinese medicine slag etc. are for sponge gourd nursery.
Seedling factorial praluction (point disk seedling growing) because of have energy-conservation, production efficiency is high, seedling quality good, slow seedling is fast, survival rate advantages of higher and more and more come into one's own (Jilin, field, 2000; Lian Zhaohuang, 1992).Seedling medium is the basis of point disk seedling growing, and the good physicochemical character of matrix provides the guarantee of good growing environment for plant, for seedling provide stable coordinate water, gas, fertilizer, structure somatomedin.Except supporting, except fixing plant, seedling medium the more important thing is the effect of serving as " root system of plant nutrition library ", makes to be preserved from the nutrient of nutrient solution, moisture, root system of plant therefrom Selective absorber (the shy moral of Wang, 1998) as required.Directly and base contact, the quality of its quality directly determines nutrition supply and the growth and development state of cultivating plants to root system of plant.
Substrate composition is chaotic in the market, and cause the physicochemical property of matrix bad, permeability is poor, and water retention capacity is bad, thus makes plant growing way bad, and plant is short and small, yellow leaf, resistance are poor, has a strong impact on the quality of point disk seedling growing.Therefore, suitable substrate composition is chosen according to the habit of growth of Different Crop very necessary.
Summary of the invention
Goal of the invention: because sponge gourd point disk seedling growing in prior art also adopts the matrix of the reusable edibles such as mushroom slag, carbonization rice husk to replace, uses in seedling raising process that these matrix sponge gourd growing ways in seedling stage are weak, growing way is irregular, and resistance is poor.Existing seedling growing process still adopts the peat composed of rotten mosses more, and the trans-regional cost of transportation of the peat composed of rotten mosses is higher, and the peat composed of rotten mosses develops the negative effect caused ecotope in a large number.In order to solve the problem, this invention exploits a kind of not containing the sponge gourd grow seedling nutritional matrix of the peat composed of rotten mosses, and providing corresponding formula.
Technical scheme: the invention provides a kind of sponge gourd grow seedling nutritional matrix, it is characterized in that comprising following component: one or more in coconut husk, vermiculite, perlite.Concrete, coconut husk of the present invention, vermiculite and perlite, by volume number meter, each component proportion is coconut husk 25 ~ 35 parts, vermiculite 10 ~ 15 parts, perlite 5 ~ 10 parts.
Concrete, sponge gourd grow seedling nutritional matrix of the present invention, has several attainable formula, for not being:
Component is coconut husk and perlite, by volume number meter, and each component proportion is coconut husk 25 parts, perlite 25 parts.
Component is coconut husk and vermiculite, by volume number meter, and each component proportion is coconut husk 30 parts, vermiculite 20 parts.
According to formula of the present invention, what obtain is composite interstitial substance, is particularly suitable for sponge gourd nursery, and this matrix stable in physicochemical property, better, unit weight is 0.06 ~ 0.47g/cm for permeability and water retention property
3; Total porosity is 72 ~ 87%.EC value is 0.13 ~ 0.71ms/cm.PH value is 5.68 ~ 7.12.EC value and pH value can meet the needs of sponge gourd nursery completely.
Further, preferred embodiments of the present invention are: formula coconut husk 25 parts, perlite 25 parts, the unit weight of gained nutrient matrix is 0.06g/cm
3; Total porosity is 87%; EC value is 0.15; PH value is 6.51.
The preferred scheme of the present invention: formula coconut husk 30 parts, vermiculite 20 parts, the unit weight of gained nutrient matrix is 0.47g/cm
3; Total porosity is 72%; EC value is 0.13; PH value is 7.12.
Beneficial effect: 1, in the present invention, coconut husk is biodegradable material, its residuals can process as soil, very convenient.Can also substitute the peat composed of rotten mosses, the peat composed of rotten mosses is non-renewable resources, and the excessive exploitation peat composed of rotten mosses causes certain loss to ecotope, is unfavorable for the ecological balance simultaneously.
2, in grow seedlings of vegetable process, main first-selected matrix is the peat composed of rotten mosses at present, but in actual production, runs into bottleneck, peat composed of rotten mosses skewness, and the cost of transportation is high, considerably increases production cost.Cocoa husk is holomorphosis resource, and in the result time limit of coconut palm, it constantly bears new fruit, and thus new raw material can supply continuously, for the production of.
3, this formula safety non-pollution, there is economizing on resources, reduce production cost, effectively can improve Quality of Seedlings and efficiency etc., be conducive to promoting the efficient and sustainable development of factorial seedling growth abridged edition.
4, this matrix formulations is composite interstitial substance, and be applicable to sponge gourd nursery, obviously can promote growth of seedling than conventional seedbed system, the physical signs such as seedling vigorous index, root activity, net photosynthesis are all high than conventional seedbed system.
5, matrix formulations stable in physicochemical property of the present invention, permeability and water retention property better.EC value and pH value can meet the needs of sponge gourd nursery completely.
