Description
Technical field
The present invention relates to a kind of plant seeds by airplane hedysarum scoparium seed-pelleting method under rainfall controls, belong to aerial seeding seed pelletized
Technical field.
Background technology
Nineteen fifties, scattered seeds by airplane for afforestation technology is by incoming China of western countries.Owing to scattered seeds by airplane for afforestation has speed
Hurry up, low cost, instant effect, planting are even, scope is wide, the advantage such as good in economic efficiency, and its plant seeds by airplane area is gradually increased.
During the firm incoming China of plant seeds by airplane technology, main employing naked seed plant seeds by airplane, seed is not done any process, is used directly to fly
Broadcast.But owing to the seed of plant seeds by airplane is relatively light, cause aerial seeding seed drift and displacement.Particularly desert area is due to drought,
The planting percent of aerial seeding seed cannot be ensured；Dodging bud phenomenon is to reduce the main cause of plant seeds by airplane effect.Meanwhile, good the putting down of land occupation condition
Slow sand ground is fewer and feweri, and many local plant seeds by airplane districts are increasingly turned to the remote husky severe land occupation condition of great Sha, this plant seeds by airplane district Density of dune
Greatly, sand dune relative altitude is high, and vegetation mobility rare, husky is strong, little precipitation.Severe land occupation condition, exacerbates seed drift, position
Moving, dodge the generation of the phenomenons such as bud, plant seeds by airplane achieves noticeable achievement reduction.
Therefore, aerial seeding seed is treated as one of key factor affecting plant seeds by airplane effect.At present, plant seeds by airplane is with pelletized
Seed coat agent mainly increases the weight of seed, and after preventing plant seeds by airplane, seed is with wind drift and displacement, but still without solving rainfall
The sudden strain of a muscle bud phenomenon that deficiency causes, dodging bud phenomenon is the main cause causing plant germination rate and survival rate after plant seeds by airplane low.
Summary of the invention
For the deficiencies in the prior art, the present invention provides the plant seeds by airplane hedysarum scoparium seed-pelleting side under the control of a kind of rainfall
Method, the method for the present invention mainly regulates water-retaining agent content in pill pelleting seed, it is ensured that rainfall just starts more than 10 millimeters of seeds
Sprout；Meanwhile, by adding nutrient (a large amount of and trace) to pill pelleting seed, providing one to seed germination can give birth to rapidly
Long microenvironment, improves planting percent further.
Technical scheme is as follows:
Plant seeds by airplane hedysarum scoparium seed pill pelletizing formula under the control of a kind of rainfall, it forms and weight percent content is: 10
～the Pulvis Talci of 30%；40～the bentonite of 80%；0～attapulgite (hereinafter Pulvis Talci, bentonite and the attapulgite of 30%
The mixture of powder is referred to as powder)；2～the water-retaining agent of 6%；0.15～the sticker of 0.80%；0.01 ‰～0.1 ‰ plant growings
Regulator；5～10% nutrient substance；And the percentage by weight sum of all the components is 100% in formula.
Described water-retaining agent is polyacrylamide.
Described sticker is polyvinyl alcohol or sodium carboxymethyl cellulose.
Described plant growth regulator is root-inducing powder 6.
Described nutrient substance is potassium dihydrogen phosphate and trace element, and preferred weight ratio is potassium dihydrogen phosphate: trace unit
Element about 100:1, wherein trace element includes copper, zinc, manganese, molybdenum, boron or its mixture.
The method of the plant seeds by airplane hedysarum scoparium seed-pelleting under the control of a kind of rainfall, comprises the following steps that
A hedysarum scoparium seed is mixed adding additives with powder with the weight ratio of 1:6 and adds binding agent by (), make hedysarum scoparium seed pill
Change；Middle powder weight accounts for the 95～97% of total powder weight；
B pelletized hedysarum scoparium seed, a small amount of powder, water-retaining agent, nutrient mixing are added growth regulator by (), make pill
Change seed and obtain microenvironment and the nutrition of growth needs；Wherein powder weight accounts for the 3～5% of total powder weight；
C pelletized good seed is sieved by (), be dried and obtain pelletized hedysarum scoparium seed
Beneficial effects of the present invention is as follows:
By adding Pulvis Talci, bentonite and attapulgite in the present invention, make hedysarum scoparium seed increase weight about 7 times, can effectively keep away
Exempt from aerial seeding seed drift and displacement；By the content of water-retaining agent in regulation hedysarum scoparium seed-pelleting seed coat agent, it is ensured that hedysarum scoparium seed
Can be in the case of rainfall be more than 10mm, it is provided that the enough moisture that seed germination needs；By regulation hedysarum scoparium seed-pelleting
The content of sticker in seed coat agent, it is ensured that seed has good cracking severity, it is ensured that do not crush, when seed germination
Cracking rapidly；Add plant growth regulator, plant root growth can be promoted, improve survival rate of seedlings and seedling vigorous index；Nutrient
The interpolation of matter, is provided that the microenvironment that a pill pelleting seed is sprouted, meets seed and mushroom out institute under severe growth conditions
The nutrition needed, improves seedling vigorous index.
