A kind of sweet osmanthus seedling cultivation matrix and preparation method thereof
Technical field
The invention belongs to agricultural technology field, be a kind of sweet osmanthus seedling cultivation matrix and preparation method thereof.
Background technology
Sweet osmanthus is a kind of important ornamental plants in garden, on landscape engineering through being commonly used for hedgerow, cover plant etc.The sweet osmanthus growth of seedling is slow, and often needing could effectively increase the growth of seedlings amount by strengthening rich water quality management, has also increased production cost and artificial the input simultaneously.Generally use the potted plant seedling of nutrition pot in the production, so both can control root growth, be conducive to daily rich water centralized management again, when promotion is grown tall, also improved production cost efficient.Matrix has vital role to potted plant growth of seedlings.Usually utilize local rural area soil, loess etc. as cultivation matrix, but such matrix fertilizer efficiency owes long, need constantly to replenish various nutrients, and ventilation property is poor, harden easily during arid, be unfavorable for root growth.Though more existing sweet osmanthus matrix are making moderate progress aspect ventilation property and the fertility, its major ingredient is peat soil, vegetable mould, has non-renewablely, and cost is higher.Therefore, developing some has with low cost, fertilizer efficiency new matrix lasting, that be beneficial to seedling growth and becomes very urgent.
In the most sweet osmanthus output zone in China south, also be paddy rice plantation producing region, the rice husk resource is very abundant, but fails by a large amount of efficient development and use, often directly burns or pours the river into, causes the pollution of sky G﹠W.
The present invention just is being based on above factor, uses loess, rice husk and perlite, has well improved ventilation property and the fertilizer efficiency of sweet osmanthus potting media, can take full advantage of the locality again simultaneously and enrich low-cost resource, make production cost reduce greatly, thereby application prospect is extensive.
Summary of the invention
The object of the present invention is to provide a kind of sweet osmanthus seedling cultivation matrix with low cost, simple for production, to take full advantage of local agricultural resource, promote production and the development of sweet osmanthus nursery stock.
In order to realize purpose of the present invention, we are according to the practical situation in China south rice producing region and the degree that is easy to get of base starting material, after choosing rice husk and handling by fermentation, are mixed with sweet osmanthus seedling cultivation matrix according to different ratios, compare test, formed the present invention.It is to the effect that: the main component of matrix comprises loess, rice husk and perlite, and its ratio is loess 20%, rice husk 60%, perlite 20%.Rice husk is handled by fermentation, and its fermentation process is that rice husk adds water to water content about 50% after in heaps, adds EM bacterium liquid and the amount of urea that ferments again, covers with plastics film.Treat fermentation heap be warming up to 60 ℃ after turning, be warming up to 60 ℃ after turning again, treat that the fermentation heap temperature is down to the success of fermenting when consistent with temperature.Wherein, the fermentation process of EM bacterium is, EM bacterial classification, brown sugar, water by after 1: 1: 50 the mixed sealing and fermenting 3-7 days, are treated that pH value is get final product the use of dilution back between the 3-4 time.
Advantage of the present invention is:
1, remarkable to the effect that promotes the sweet osmanthus growth of seedling.Matrix is pH less than 7 subacidity, is particularly suitable for the characteristic of sweet osmanthus happiness acid.Contain a large amount of organic matters, make this matrix nutrition abundant.In addition, also have good water-retentivity and nutrient preserving capability.
2, raw material is easy to get, and is with low cost.Rice husk is China's modal agricultural wastes in paddy rice producing region, usually adopts the mode of burning to handle, and not only polluted air has also caused certain waste.The present invention is turned waste into wealth it.
3, making method is simple.Only need fermentative processing to use, add EM bacterium liquid during fermentation and can shorten fermenting process greatly.
Specific embodiment:
This test is positioned at yueyang, hunan Bai Xiang town with implementing.Implement in mid or late October, 2011.The used rice husk of present embodiment derives from local rural area.Implementation step is as follows:
(1) rice husk fermentation
Earlier with the fermentation of EM bacterium, method be with EM bacterial classification, brown sugar, water by 1: 1: 50 mixed after sealing and fermenting 3-7 days, treat that pH value is between the 3-4 time, the rice husk that adds water content 50% after dilute 5 times respectively covers with plastics film in piling.The rice husk heap is added with amount of urea in advance, in order to adjust carbon-nitrogen ratio.Treat fermentation heap be warming up to 60 ℃ after turning, be warming up to 60 ℃ again after turning again, treat that the fermentation heap temperature is down to the success of fermenting when consistent with outer temperature.In in early March, 2012, the rice husk that ferments is sterilized with derosal.
(2) matrix preparation
On March 12nd, 2012, with loess, the rice husk that ferments and perlite by loess 20%, rice husk 60%, the ratio mixing of perlite 20%.
(3) dress basin and management
According to the conventional cultivation method sweet osmanthus cuttage seeding is packed in the black plastic nutrition pot, final-period management is only watered in good time, fertilising.In carrying out increment investigation 14-15 day in November, 2012, the average plant height 30.8cm of the sweet osmanthus of this matrix exceeds 15% than contrast (be matrix with loess), promotes the effect of growth obviously to be better than contrast.
