Embodiment 1
Fig. 1 is the structural schematic diagram of seeding apparatus 100 provided in this embodiment.Referring to Fig. 1, in the present embodiment, it is no-tillage
Precision planting depth seeding apparatus 100 include seeder ontology 110 and wrapping film 120, wrapping film 120 is by degradable
Material or/and water-permeable and air permeable material are made, and the seeds chamber 111 for putting seed 112 is provided on seeder ontology 110 and is planted
Being open on the side of seeder ontology 110, wrapping film 120 for sub- chamber 111 is provided with scale area 121, on scale area 121
It is provided with graduation mark 122, wrapping film 120 is coated on the surface of seeder ontology 110 and for seed 112 to be sealed in seed
In chamber 111.
Wrapping film 120 is coated on the surface of seeder ontology 110 and seed 112 is sealed in seeds chamber 111, realizes
The storage of seed 112.When sowing to seed 112, without scratching topsoil, directly seeding apparatus 100 is inserted into
In soil, to make the seed 112 in seeds chamber 111 and the wrapping film 120 being coated on outside seeder ontology 110 be inserted into together
In soil, also, according to the characteristic of seed 112, graduation mark 122 is observed, the accurate optimum that is planted in of seed 112 is made to bury
Depth.Seed 112 is planted in optimum buried depth precisely to plant, is conducive to the sprouting of seed 112 and the survival of seedling,
Avoid 112 prey of seed or loss.And Soil tillage need not can be kept original soll layer structure, it reduces secondary
The probability of happening and degree of soil erosion.
That is, in the present embodiment, seeding apparatus 100 belongs to disposable product, when sowing, by seeding apparatus
100 are inserted into soil, to make 112 Precise sowing of seed in the seeds chamber 111 on seeding apparatus 100 in the soil, seed
112 depth of planting is more accurate.(1) seed 112 is precisely buried according to 112 optimum buried depth of seed, is conducive to plant
Son 112 is sprouted and seedling survival, reduces the danger of seed 112 prey and loss.It is suitable for that wind is big, slope is steep, rainwater is more, catches
Eat the soil more than 112 animal of seed.(2) it need not ditch in earth's surface or open cave, seeding apparatus 100 is directly inserted into soil, most
The primitiveness of original soll layer structure is kept to limits to reduce probability and degree that secondary soil erosion occurs.It is suitble to
The operation on abrupt slope and complicated landform.(3) it is suitable for the region of precipitation rareness and non-irrigated condition, seed 112 is sprouted and is more stranded
Difficult Seeds of Wild Plants 112, it is contemplated that effect is good, saves seed 112.This seeding apparatus 100 is suitble in different land types
Upper sowing can especially be sowed in steeper slope.
After seeding apparatus 100 is inserted into soil, wrapping film 120 is degraded, and the degradation time of wrapping film 120 is small
