Abstract
The invention discloses a method for manufacturing a non-woven seedling-growing culture medium by using rice straw fibers and ramie fibers. The method includes cutting rice straws into sections of 2-4cm, placing the cut rice straws into a sodium hydroxide solution with mass concentration as 30-50%, conducting softening processing on the cut rice straws, washing the rice straw fibers obtained in the softening process for a plurality of times to remove surplus sodium hydroxide, drying the rice straw fibers for standby application, evenly mixing the ramie fibers and the rice straw fibers according to certain ratio, manufacturing a fiber net with density as 100-150g/m<2> through a dry net forming method, immersing the fiber net into an adhesive and conducting hot air drying and forming. The manufactured non-woven culture medium can be used as a lawn culture medium, is convenient to transport and can be cut into different sizes according to requirements. Growing can be conducted by laying the culture medium, sowing seeds on the medium, watering and adding a nutrient solution. Lawn transplanting can be conducted after seedlings emerge. The culture medium is a biological material and can be degraded naturally in the lawn growing process.
Description
Technical field
What the present invention relates to is a kind of manufacture method for the degradable seedling medium of cultivating turf, in particular a kind of method of using rice straw fiber and ramee to make non-woven raise seedling culture medium.
Background technology
Nonwoven fabric is planted a kind of technology that band is the turf plantation of giving birth to.Grass seeds is evenly placed between the two-layer nonwoven, form nonwoven fabric and plant living band, be used for cultivating turf.Existing nonwoven fabric is planted and is given birth to that band is many to be made with chemical fibre, cultivates the lawn and implants non-degradable behind the ground, can cause damage to ecological environment.Nonwoven fabric is planted and is given birth to band grass-seed is placed between the two-layer nonwoven, making, can cause damage by grass-seed in the transportation, and grass-seed plant give birth to band cause skewness easily, influence the sprouting of grass seeds and the quality on lawn.
In recent years, China's agricultural enters a new development opportunity, and agricultural is good harvest year after year.But along with China's grain increases production every year, produce a large amount of stalks.Grain harvesting back stalk needs in the field in time to handle, otherwise will influence the plantation of crop of following season.And the method that burn in the field of generally adopting brings serious environmental to pollute.After the processing mode of burning when the field is forbidden by strictness, how to open up the channel that utilizes of stalk, increase utilization rate and become problem demanding prompt solution.
To the cellulosic utilization research in the stalk, mainly concentrate on the making artificial board at present, but the product processed performance is compared big gap in addition with common wood-based plate thus.Because the length of stalk fibre is too short, can not be directly used in and spin cotton and weave cloth, and can't make woven textile products with traditional method.How to utilize such staple fibre, be the technical barrier that the scientific research personnel faces always.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of method of using rice straw fiber and ramee to make non-woven raise seedling culture medium is provided, make degradable environmental protection seedling medium.
The present invention is achieved by the following technical solutions, the present invention includes following steps:
(1) rice straw is prescinded to 2～4 ㎝ longly, be positioned over mass concentration then and be in 30～50% the sodium hydroxide solution, soften processing, the rice straw fiber that makes after the processing is repeatedly cleaned remove dry for standby behind the unnecessary NaOH;
(2) ramee and rice straw fiber are mixed with certain proportion, utilize dry-laying, making surface density is 100～150g/m
2Fiber web;
(3) with the agent of above-mentioned fiber web dip bonding, the hot-air seasoning moulding gets final product.
In the described step (1), the softening time of handling is 20～40 minutes, and bath raio is 1:20～1:40,60～90 ℃ for the treatment of temperatures.Reach that by above-mentioned technology the rice straw fiber softening is suitable, satisfy the demand of subsequent technique.
In the described step (2), the ratio of ramee and rice straw fiber is 1:1～3:7.
As one of optimal way of the present invention, in the described step (3), adhesive is gelatin and/or carboxymethyl cellulose, binder concn 2～4%.Select gelatin and/or carboxymethyl cellulose, not only can realize smoothly bonding, convenient degraded simultaneously, environmental sound, very environmental protection.
The present invention has the following advantages compared to existing technology: the present invention suitably softens processing to rice straw, makes it to be suitable for processing.The culture matrix that makes, material environment friendly, biodegradable.Product transport is convenient, can substitute soil as seedling medium.The non-woven culture medium of making can be used as the lawn culture medium and uses, and convenient transportation can be tailored size as required.With the culture medium tiling, seed is sowed in the above, and watering also can be added nutrient solution, can cultivate.Carrying out the lawn after emerging transplants.Culture medium is biomaterial, but in the lawn growth process natural degradation.
