Technical field

The present invention relates to sowing, also relate to sapling and transplant, specifically, relate to bootstrap technique by plant seeds by airplane sowing or transplanting sapling.

Background technology

In recent years, the desertification on desertification of land and territory, stony desertification, sand and dust of Zeng Jiaing and sandstorm weather year by year, and the greenhouse effect that cause of carbon dioxide increase global temperature year by year, have become the environmental problem of people's growing interest.One of solution to this problem is by the scattered seeds by airplane for afforestation grass planting.The scattered seeds by airplane for afforestation grass planting is that seeds or the grass seeds that will handle broadcast sowing ground from aircraft, and its speed is fast, efficient is high, it is big to broadcast sowing area, for large-area soil a kind of good method of can yet be regarded as.But plant seeds by airplane at present is not enough to some extent, is difficult to promptly guarantee that seed gos deep among the soil on the face of land, has many seeds can not germinate because of lack of water, no soil, and being difficult to of germination survives.For this reason, in recent years, the domestic technical scheme that has some to overcome the above problems is applied for a patent, and for example ZL91108555.6 number " high eveness aerial planter ", this patented technology can be regulated the amount of sowing seed at any time by quantitative disk; ZL200410075014.6 number " large grain coating agent for aerial seeding " and CN200410066572.6 number " herbage seed wormwood artemisia seed-pelleting dressing agent and coating method " by giving seed pelleting, realizes that percentage of seedgermination height, late growing stage are effective; 200610041992.8 number " being applicable to the plant nursery stock grower of desert plant seeds by airplane " designed plant nursery stock grower, can solve the low problem of desert large tracts of land afforestation survival rate.Should say above these inventions all at scattered seeds by airplane for afforestation in the past, the defective that the grass planting survival rate is low all is effective invention, but people are also continuing to explore better plant seeds by airplane method.

Summary of the invention

Purpose of the present invention just provides a kind of guide body with native plant seeds by airplane and the empty seedling of planting trees, this guide body can directly be broadcasted sowing seeds, grass seeds or sapling on the soil of desertification or desertification, stony desertification by plant seeds by airplane, is a kind of easy making, cost is low, the sapling survival rate is high plant seeds by airplane apparatus.

To achieve the above object of the invention, the inventor is the similar gyro of a kind of profile through the guide body that research provides, and its shell is made with degredation plastic, housing can be a cylinder, also can be cuboid, the bottom be that angle is 45 °～90 ° a cone, and its inside is the high walk of proportion; There is the earth with fertilizer at the middle part, and seed chamber or sapling chamber are arranged therebetween, also has the water bag chamber, and seeds or grass seeds place in the seed chamber, and sapling places sapling indoor; The water bag of being made by the polypropylene film of sealing places water bag indoor, and 1～4 bamboo let broken bag pin vertically is equipped with in the bottom.

Guide body is the time of freely falling body aloft, can be calculated by the physics correlation formula, that is:

$t=\sqrt{2h/g}$

Guide body also can be calculated by the physics correlation formula, that is: the impulse force that ground produces

$\stackrel{\&OverBar;}{N}=\mathrm{<figure-callout\; id="2"\; label="M"\; filenames="A20071007783200081.png"\; state="\{\{state\}\}">M</figure-callout>}\sqrt{2\mathrm{gh}}/\mathrm{\&tau;}+G=\mathrm{Mg}(1/\mathrm{\&tau;}\&times;\sqrt{2h/g}+1)$

In the formula, N is the average impulse force of guide body to ground surface, just to the average normal pressure of ground surface;

M is a guide body weight;

T is the time that guide body drops down onto ground;

H is the height of freely falling body

G is a free-fall acceleration, 9.8m/s ²G is a free-fall acceleration.

τ be falling bodies when contacting with ground to stopping the motion time at that moment of falling, this time can't try to achieve, and can only record from practice, but this time is very short, is about 10 ^-2～3 * 10 ^-1Between second.

The inventor points out, as long as the own wt of guide body and the high computational of broadcasting sowing are proper, whole guide body falls to ground, can insert the certain degree of depth of ground surface soil, realization is seed or the sapling extensive farming purpose in sandy soil or waste soil, and makes its growth key element and germination with water, soil, fertilizer survive condition.Beyond any doubt, this will make and be with native scattered seeds by airplane for afforestation and the sky seedling of planting trees to be achieved.

Guide body also has a function--and be about to manual manufacture plastic flower or plastics cypress and be fixed on to throw in the guide body and broadcast the drift sand area, form artificial shelter forest, can reduce drift sand and flow or reach the effect of fixing the sand.

The guide body of native plant seeds by airplane of band provided by the invention and the empty seedling of planting trees, solve seed in traditional plant seeds by airplane method and can not enter soil, germination rate is low, survival rate is also low problem fully, also solved the key element problem of seed sprouting or sapling growth, especially in the unmanned area of desertification of land and desertification, be a kind of effective apparatus of realizing plant seeds by airplane kind tree, planting grass.Compared with the prior art, this guide body have simple in structure, cost is low, effective characteristics easy to use; The sapling root system has the earth protection, and is ruined few, helps sapling and survives; In addition, adopt guide body to carry out the sky seedling of planting trees, can carry out the sky seedling of planting trees in south the whole year at spring, summer, Qiu Sanji, long if aerial seeding seed can carry out the activity duration whole year.Guide body also has a function--and be about to the plastic flower of manual manufacture or plastics cypress and be fixed on to throw in the guide body and broadcast the drift sand area, form artificial shelter forest, can reduce drift sand and flow or reach the effect of fixing the sand.
