Abstract

The present invention discloses a soilless lawn and a making method thereof. The present invention aims to provide a novel advanced soilless lawn convenient to move for many times and a making method thereof. Grass seeds processed by using a physicochemical method are sown on a breeding bed to grow to form the soilless lawn, and the breeding bed is composed of a sprout protecting layer, a fertilizing layer, a substrate layer and a bottom layer. The making method comprises the steps: the grass seeds are sown on the substrate layer on which the fertilizing layer and the sprout protecting layer are covered; after the grass seeds sprout to become young sprouts, mancozeb is immediately sprayed on the leaf surface of each of the sprouts; different nutrient solutions are used in different stages during the growing period of grass; and finally, the grass grows into a lawn. The soilless lawn overcomes the defects of poor adaptability and easy degradation and fragmentation of a bed body of the original lawn, and the soilless lawn is suitable for greening environment.

Description

A kind of lawn soilless and manufacture method thereof

Technical field

The present invention relates to the soilless culture in the gardening,, the invention still further relates to the manufacture method of this lawn soilless in particular to the lawn of soilless culture.

Background technology

Cultivating the lawn is one of method of greening environment.Calendar year 2001, lawn soilless comes out, and has been documented in No. 01108799.4, the Chinese patent application part.Though this lawn have save land resources, cultivation easily, advantage such as convenient transportation, through practice, this lawn but exposes some shortcomings, the one, to the bad adaptability of environment, use this lawn in the open air, easily lodge when wind is strong, shine the back for a long time easily to wither; The 2nd, degradation speed is too fast, and life cycle is short; The 3rd, inoculating bed poor toughness, easy fracture.

Summary of the invention

Purpose of the present invention just is to provide a kind of novel senior lawn soilless of growing the place, can resist high wind and being exposed to the sun, being convenient to repeatedly move do not selected, and makes it can extensively plant various places, greening environment.

Another object of the present invention provides the manufacture method of novel senior lawn soilless.

Lawn soilless is that grass seeds is broadcasted sowing the lawn that growth is got up on inoculating bed, and novel senior lawn soilless grass seeds of the present invention is handled through materialization before broadcasting sowing; Used inoculating bed is made up of sprout-protecting layer, fertilizer application layer, hypothallus, bottom.

Sprout-protecting layer uses ultrathin nonwoven with holes, its effect be protection broadcast sowing behind the grass seeds young shoot not by big wind scrape, strong sunlight is exposed to the sun or rain drop erosion, after young shoot is emerged, in time remove.The nonwoven of taking off can be reused.

Fertilizer application layer is that fallen leaves (for example pine tag---withered pine needle), skin, stalk, the even mixed-stacking of root with plant forms to certain thickness, applies organic and inorganic and trace element fertilizer at this layer.Its effect is to give the growing environment of the similar soil of grass seeds and enough growth nutrient; After throwing off sprout-protecting layer, it can continue to protect seedling.Its thickness is 8～12mm.

Hypothallus is the mesh carrier of being mixed and processed with native fiber and synthetic fibers, and its effect is to keep moisture and fertilizer, prevents to run off, and giving careless seedling has life condition and the growing environment that is better than soil.Usually, the ratio of native fiber and synthetic fibers is (1～1.1): 1, and native fiber commonly used is a cotton fiber, synthetic fibers commonly used are one or more in polyvinyl chloride fibre, terylene, the acrylic etc.These fibers are become with the special-purpose machinery tearing be tiled on the bottom after cotton-shaped, the about 30～45mm of its thickness can decide the requirement of degradative phase according to the user, requires degraded hurry up, and is thinner slightly.Certainly, can use waste and old fibre to reduce cost.

Bottom is made up of polypropylene fibre and nonwoven, tightly invests under the hypothallus, and its effect one is to support whole inoculating bed, and the 2nd, the ground of inoculating bed and storing, metope are separated by.Usually, the consumption of polypropylene fibre and nonwoven is 4: 1.

It is to be that the disinfectant of rare potassium permanganate solution of 0.1%～0.2% or 5% formalin solution (containing 2% formaldehyde) and so on soaks and carries out chemical treatment with concentration prior to seeding that the early stage materialization of grass seeds is handled, through-4～-12 ℃ freezing down or through 0～4 ℃ down refrigeration carried out physical treatment with ultraviolet irradiation again afterwards in 48 hours.Treated grass seeds not only germinates and grows reliably, and it is taken root and can become fibrous root by taproot.

The manufacture method of novel senior lawn soilless of the present invention is: at first grass seeds is directly broadcasted sowing on netted hypothallus, cover fertilizer application layer and sprout-protecting layer successively.Every 1kg grass seeds can broadcast sowing on the hypothallus of 40～65m.Sow and begin after 3～6 days to germinate, the growth downwards of taking root after 5～10 days, butt extends downwards gradually.Pass through in the process of the used fiber of hypothallus at its root, taproot is changed into shallow fibrous root by reticular substance.Shallow fibrous root continues to extend, and enters the hypothallus bottom at last.Because the polypropylene fibre and the nonwoven short-term of bottom can't penetrate, in order to absorb nourishment and moisture, fibrous root can only spread development towards periphery along the space of pseudostructure, forms the fibrous root net gradually.This fibrous root net provides nutrition and moisture for the growth of careless strain on the one hand, firmly careless strain is fixed on the inoculating bed on the other hand.Inventor is desired just for this.After grass seeds germinates the formation seedling, use 0.1% agricultural chemicals mancozeb (mancozeb) sprinkling seedling blade face immediately, to eliminate lawn damage by disease and insect hidden danger.In each stage of careless strain growth, use different special nutrient fluids, promote careless strain to grow up, finally form lawn soilless.

Sowing to germination period, needn't apply fertilizer.Form the initial stage seedling, the prescription of special nutrient fluid is: nitrogenous 0.3% (in N, down together), phosphorus 1% is (with P ₂O ₅Meter, down together), potassium 0.7% is (with K ₂The O meter, down together); Be under 10～25 ℃ the situation, to spray 1 time in per 3 days at temperature, need continuous administration 3 times.Through about 10 days, seedling has formed certain root system and tender leaf, enters the growth stage, need ask for more nutrient to the outside, and the prescription of this stage special nutrient fluid is: nitrogenous 1%, and phosphorus 1.8%, potassium 0.6%, boron 0.003%, iron 0.01%, copper 0.0006%; Used 1 time in per 5 days.After using 2 times, use phosphorous 1% phosphate fertilizer separately 2 times.So intersect fertilising till the lawn basically forms.After the lawn basically formed, the prescription of special nutrient fluid was adjusted into: nitrogenous 1.8%, and phosphorus 0.8%, potassium 0.5%; Can use throughout the year.But at high temperature season, the special nutrient fluid nutrient will suitably reduce, and filling a prescription is: nitrogenous 0.5%, and phosphorus 0.2%, potassium 0.2%; And adopt a small amount of mode repeatedly to use.

The base fertilizer of preparation special nutrient fluid comprises urea, normal superphosphate, potassium sulphate, double superphosphate, MAP, diammonium phosphate, borax, ferrous sulfate, copper sulphate etc.

Use novel senior lawn soilless of the present invention, can overcome original lawn soilless and easily lodge, be afraid of to be exposed to the sun, be afraid of shortcomings such as heavy rain, have that survival rate height, view are strong, growth is rapid, cheap, manageable, easy maintenance, conveniently transport, have no pollution, assembly unit arbitrarily, random plurality of advantages such as cutting, can under many environmental conditions, use, carry out plane or three-dimensional contouring, for people build green living space.

Embodiment

Embodiment directly broadcasts sowing the 1kg grass seeds at 60m ²The pseudostructure layer on, cover fertilizer application layer and sprout-protecting layer successively, sow and begin after 3～6 days to germinate, the growth downwards of taking root after 5～10 days, grass seeds germinate form seedling after, immediately with 0.1% agricultural chemicals mancozeb sprinkling seedling blade face, sowing to germination period, needn't apply fertilizer.Form the initial stage seedling, with prescription for nitrogenous 0.3%, phosphorus 1%, the special nutrient fluid continuous administration of potassium 0.7% 3 times, generally (temperature is 10～25 ℃) sprayed 1 time in per 3 days.Through about 10 days, seedling has formed certain root system and tender leaf, enters the growth stage, is nitrogenous 1% with prescription, phosphorus 1.8%, potassium 0.6%, boron 0.003%, iron 0.01%, the special nutrient fluid of copper 0.0006% was used 1 time in per 5 days, after using 2 times, used phosphorous 1% phosphate fertilizer separately 2 times.So intersect fertilising till the lawn basically forms.After the lawn basically forms, prescription is adjusted into: nitrogenous 1.8%, phosphorus 0.8%, the special nutrient fluid of potassium 0.5% is used throughout the year.As hot weather, suitably reduce the special nutrient fluid nutrient.Can produce 60m like this ²Novel senior lawn soilless.
