Abstract

The plant fibre covering consists of plant fibre, water and adhesive and the plant fibre with different length and diameter is produced with timber and reed through peeling, slicing, steam grinding, vacuum coloring, drying and packing. When used, the plant fibre is mixed with adhesive, seed and water before spraying-sowing. The plant fibre is easy to loose in water, and has good hydroscopicity, water-maintaining property, adhesiveness and supportability, and the mixture as a semi-osmotic paste with moisture-preserving function makes seed resistant to wind and rain loss.

Description

Plant fibre liquid covering for weed seeding and manufacture method thereof

The invention belongs to the coating protection thing of grass seeds and the production method of this coating.

Existing grass seeds is coated the preliminary working material, sawdust, rice husk etc. that the protection thing has wood pulp, particle board and the fiber board of paper grade (stock).These coat the protection thing and have following shortcoming and defect.The wood pulp of paper grade (stock) is the chemical treatment fiber, its thin and delicate, caking, and not loose in water, permeability is poor, and the germination that influences seed survives, and its cost is high again, and resource is also few.The preliminary working material of particle board and fiber board is irregular, and is long or meticulous, and the impurity smalls is many, is difficult to into net, and seed also is difficult for being evenly distributed therein.The rice husk water binding capacity is poor, equally with sawdust then granulates as reprocessing, though laxity is arranged, can not overlap mutually, support, and spreadability is poor, and after planting it is easily lost by wind with seed, also easily by the rainwater leaching loss, does not reach the purpose that coating protects seed sprouting to take root.

The objective of the invention is to develop a kind of covering that is applicable to that the grass seeds liquid state is sowed grass seeds by duster, that vegetable fiber in this covering should have is loose, water binding capacity good, can overlap, support, easily become net mutually, seed can evenly distribute therein, seed and covering all are difficult for being lost by wind after sowing grass seeds by duster, and also are difficult for by the characteristics of rainwater leaching loss.The manufacture method of vegetable fiber in this covering is provided simultaneously.

Covering of the present invention is made up of vegetable fiber, water, adhesive, and wherein vegetable fiber is made up of after processing materials such as the more timber of fibrous substance, reeds.Being shaped as of processing back vegetable fiber: length is 2--10mm, and diameter 0.2--1mm also comprises the wadding fibrous thing that the fiber fines particle is formed.They separately percentage by weight be respectively: fibre length accounts for 25-45 at 5--10mm, diameter at the vegetable fiber of 0.8--1mm, fibre length accounts for 35--55 at 2--5mm, diameter at the vegetable fiber of 0.2--0.8mm, fibre length accounts for 15-35 at 0.1--2mm, diameter at the vegetable fiber of 0.05--0.2mm, and the moisture content of fiber is≤12%.

The manufacture method of vegetable fiber is: get the timber peeling, with the woodchip after the peeling, the specification of wood chip is (1--2cm) * (1--2cm) * (0.1-0.2cm), with wood chip be put in the defibrator logical steam grind, after grinding cotton-shaped xylem fibre, xylem fibre is carried out vacuum dyeing, again the xylem fibre after the dyeing is carried out drying back packing and get final product.

Vegetable fiber of the present invention is easily loose in water, do not lump, and water imbibition and water binding capacity are preferably arranged, and tack is good, and fiber links support mutually, has good permeability.It mixes the back with adhesive, water and grass seeds and becomes semi-permeable sticky shape, forms one deck cover layer on the face of land through sowing grass seeds by duster after, and adhesive at fiber surface formation film, have the minimizing water evaporates, the effect of economizing on water and preserving soil moisture.Especially it is difficult for being lost by wind, also is difficult for by the advantage of rainwater leaching loss.The usefulness that is suitable for plantation bank protection grass on the bigger gradient soil in road both sides.Also can be used for golf course, sports ground, the sowing of large tracts of land lawn, city.Its manufacture method is simple, and is easy to operate, and is convenient to large-scale industrial production and three-waste free pollution.

Embodiment one: the vegetable fiber of present embodiment is made up of the xylem fibre of following specification and percentage by weight, and fibre length is at 5--10mm, and diameter accounts for 35 at the xylem fibre of 0.8--1mm.Fibre length accounts for 40 at 2--5mm, diameter at the xylem fibre of 0.2--0.8mm, and fibre length accounts for 25 at 0.1--2mm, diameter at the xylem fibre of 0.05--0.2mm.Xylem fibre is dyed and is green, and the population mean moisture content of xylem fibre is 10%.Get the xylem fibre mixture 30% of above three kinds of specification ratios, taking adhesive 1% again, and water 59% is mixed into sticky shape with them, can sow grass seeds by duster.

Embodiment two: the manufacture method of xylem fibre is: get the undersized log peeling, with the woodchip of peeling.The specification of sheet is 2cm * 2cm * 0.2cm, wood chip is put in the defibrator logical steam grinds, through grinding after cotton-shaped xylem fibre, xylem fibre is carried out vacuum dyeing, dye green, again the xylem fibre after the dyeing is carried out drying, dry back pack finished product.

Embodiment three: the manufacture method of present embodiment xylem fibre is for making after reed pulverizing, steam grinding, vacuum dyeing, the drying.
