A kind of floriculture matrix and preparation method thereof
Technical field
The present invention relates to nutrient matrix of a kind of floriculture and preparation method thereof, particularly nutrient matrix of a kind of soilless culture of flowers and preparation method thereof.
Background technology
At present, the main raw material(s) of required cultivation matrix is a peat growing medium in farming, woods, the flower industry production, and peat growing medium can be widely used in floriculture, raising rice seedlings, indoor ornamental plant cultivation, grow seedlings of vegetable, raising seedling of cotton, lawn cultivation (golf course construction), soil melioration and fertilizer manufacturing etc.
Peat claims the peat composed of rotten mosses, peat soil, black earth, mud coal again, it is the plant remains of ancient times low temperature, wetland, be buried under the ground, accumulation through tens million of years, lower at temperature, rainwater is less or lack under the conditions of air, plant residue slowly decomposes and the special organic matter of formation, is pale brown look or light brown more.Peat is because of containing great number of organic matters, and loose, the air-and water-permeable performance is good, and the preserve moisture and fertility ability is strong, and quality is light, disease-free spore and worm's ovum.At present, in floriculture, especially grow seedlings and pot flowers in many with peat as main potting media, be that a kind of quite good pot flowers is with native.
The main plant that forms peat soil is bog moss, ice moss, sedge and other water plants.Buried condition, floristics and degree of decomposition according to peat forms can be divided into low level, a high position and medium peat three major types.High moor peat is that temperate zone high latitude plant is embedded under the stratum through long-term and piles up charing and form.Based on cotton grass genus, fountain moss platymiscium, contain great number of organic matters, degree of decomposition is lower, and nitrogen and ash element content are few, and acidity is stronger, and the pH value is between 4 to 5.Unit weight is less, and absorbent ventilate is good, but general sticking moisture is more than 10 times of its dry weight, is fit to do soilless culture substrate, but the pH value must transfer to about 5.5 to 6.0, also can be used for preparing compost.
Lowland peat is distributed in the marshland of low-lying ponding, the sedge more based on the inorganic salinity of growth needs belongs to, the reed platymiscium, and each plant species the broken branches and fallen leaves of getting off of alluviation, accumulation through the very long time forms, degree of decomposition is higher, and nitrogen and ash element content are more, a little less than the acidity, nutriment in a fertilizer validity is higher, can directly make fertilizer after the air-dry pulverizing and use.Because of its unit weight is big, suction and air capacity of soils are relatively poor, should not make cultivation matrix separately.There is a large amount of distributions in China southwest, Central China, North China and northeast.
Medium peat is marginal transitional peat, and proterties both can be used for soilless culture also between between the two, also can be used for preparing compost.
At present, the production of China's peat growing medium mainly exists following problem:
On the one hand, 46.87 hundred million tons of the total peat stock numbers of China, wherein low level meadow peat reserves are abundant, account for 98.51% of gross reserves, and middle high moor peat content rareness.China's peat physicochemical property has middle decomposition, middle organic matter, high humus, slightly acidic notable feature.It is lower to can be described as simple raw-material quality, and by the existing simple exploitation airing mode of production, technological level, scientific and technological content, product quality and economic value added are all lower, can not satisfy the actual needs that China's agricultural gardening is produced.
On the other hand, along with the continuous development of domestic seedling and plant husbandry, the cultivated area of flowers constantly enlarges, and the usage amount of cultivation matrix also constantly increases.Therefore adopt the matrix of the preparation that simply is mixed of single raw material such as vermiculite, perlite, the peat composed of rotten mosses or several raw materials to carry out traditional grow seedlings and cultivating and can not satisfy the demand of society to matrix.The general nutrition of peat growing medium that China produces is single, the growth that is difficult to seedling provides necessary nutritive element, cause that the germination rate that causes plant in the process of growing seedlings and cultivating is low, the difficulty of taking root, survival rate be low, and the physical instability of peat growing medium in the use, water imbibition is poor, subsides easily.
The lowland peat of China generally is to be formed by the weeds that grow in low moor, assorted root, form by multiple higher plant, have a large amount of lignification structures, intensive lignification peat structure has been limited to the moisture capacity and the gas permeability of peat, and its permeability and porosity are low.Root system of plant is beneficial to respiration under the environment of ventilation.If it is poor to cultivate the matrix aeration status, will directly influence the breathing of root, cause moisture and Nutrient Absorption not smooth, make acrial part (as stem, leaf, the flower) growth of plant not good, the photosynthesis ability reduces, and influences the growth of plant.
Publication number is the full nutrient matrix that the application for a patent for invention of CN1702061A discloses a kind of botanical seedling culturing and cultivation.It is that the peat of 50-70%, the perlite that weight ratio is 20-25%, vermiculite and active substance, the nutriment that weight ratio is 10-15% mix that this nutrient matrix adopts weight ratio.Peat is through high-temperature sterilization, and active substance is to be merged by multiple microorganism and plant growth regulator to be polymerized in this matrix.But the particle size of the cultivation matrix of this disclosure of the Invention differs, and after watering, the fine particle in the matrix has been absorbed in the bigger non capillary pores, and matrix shrinks and sedimentation, causes the non capillary pores of matrix to diminish, thereby has reduced the gas-water ratio of matrix; Crude fiber content in this full nutrient matrix is low in addition, and the addition of the material that need have additional nutrients has improved production cost.
Notification number is that the patent of invention of CN1117514C discloses a kind of peat composite for plant growing container and products thereof and application, it is raw material that this peat composite for plant growing container adopts China to contain abundant low level meadow peat, be equipped with acidity regulator, swelling agent and nutrition mother agent, the novel material of growing seedlings of alms bowl body of making through high-pressure molding and matrix unification.The peat raw material of this nutritive cube composition is an eutrophy peat, need be through high pressure compression moulding, and the production cost height is used lessly, has limited being extensive use of of product.
