Abstract

The invention relates to a method for cultivating dracaena arborea through a nutrient solution. The method comprises the following steps that A, a plant is processed, wherein a plant is selected, the fibrous roots are completely cut off, the main root portion with the length of 3cm-5cm remains, and the plant is immersed in carbendazim for disinfection and then is immersed in a naphthyacetic acid aqueous solution; B, field planting is conducted, wherein the plant with the treated root portion is planted in a planting basket containing ceramicite, with the depth of 5cm-10cm, and provided with ventilating holes; C, root growth acceleration is conducted, wherein the plant and the planting basket are placed in a substrate composed of perlite, the environmental condition is controlled through an automatic control system and a new root system is induced to grow out; D, root promoting is conducted, wherein the root is immersed in a water tank containing the nutrient solution, the environmental condition is controlled through the automatic control system, so that an aquatic root system suitable for growing in water can newly grow out from the top end of the root system of the plant, and therefore a commodity plant is produced. The method for cultivating the dracaena arborea through the nutrient solution has the advantages that the cultivation time is shortened to a great extent, cultivation is easy to control through an intelligent system so that factorized scale production can be achieved, and pest and disease damage is reduced so that the survival rate can be greatly improved.

Description

The nutrient fluid cultivation method of Yemen's iron

Technical field

The present invention relates to plant nutrition liquid cultivation method, specifically the nutrient fluid cultivation method of a kind of Yemen iron.

Background technology

Yemen's iron is Liliaceae dracaena plant, is adapted at growing under warm and moist, draughty environment, is common indoor good potted plant ornamental foliage plant.Prior art Zhong， Yemen Tie Tong often adopts soil cultivation, and soil cultivation on the one hand moisture is difficult to accurate control, be difficult to improve survival rate, and damage by disease and insect very easily appears in soil cultivation; Be poor growth on the other hand, be difficult to Fast-propagation and short-term and grow up to nursery stock or commodity potted landscape.

Nutrient fluid cultivation is the important means that improves industrialized agriculture production efficiency, plant to common long term growth in soil is induced, tames, cultivates, make it change the high-tech biotechnology means of new generation that can grow for a long time and form in water, its great advantage is thoroughly to have broken away from the restriction of soil condition and cultivated land resource, next is the efficient utilization to water resource, can expand planting range and space, save fertilizer, save manual labor, and acceleration plant growth, improves the quality and yield of plant.But for Yemen's iron, there is no ripe nutrient fluid cultivation method at present.

Summary of the invention

Technical problem to be solved by this invention is, a kind of nutrient fluid cultivation method that can improve Yemen's iron growth rate, survival rate is high, process of growth is easy to Based Intelligent Control Yemen's iron is provided.

The nutrient fluid cultivation method of Yemen of the present invention iron comprises the steps:

A, plant process: selected anosis, grow fine, plant with 2-3 sheet blade, first carry out root processing, its root is washed, use the scissors of having sterilized, fibrous root is all cut, retain the primary roots of 3～5 centimetre lengths, select again through the carbendazim soaking disinfection of 400～700 times of water dilutions 4～9 minutes, then soak 4～8 minutes in concentration is the methyl α-naphthyl acetate aqueous solution of 200 mg/L;

B, field planting: the plant that root was processed, plant and fill 0.5～1.0 centimetre of haydite of particle diameter, 5～10 centimetres of the degree of depth, have in the field planting basket of open-work;

C, urge root: plant is placed in to the matrix that the perlite of 0.2～0.3 centimetre of particle diameter forms together with field planting basket, by automatic controlling system environmental condition, control 20～29 ℃ of temperature in daytime, night 16～19 ℃ of the temperature of plant and root, relative moisture 40～50%, plant leaf intensity of illumination 0.9～10,000 lux, induce it to grow new root system, urge 20～30 days duration root phase;

D, short root: when matrix root is revealed out 2.5～3.5 centimetres of field planting baskets, immerse and fill in the tank of dark 4～8 centimetres of nutrient solutions of liquid, the root system of revealing out field planting basket is had in the air of 2～3 centimetre lengths on nutrient solution liquid level; By automatic controlling system environmental condition, control 20～29 ℃ of plant leaf place air temperature in daytime, night 16～19 ℃ of temperature, relative air humidity 35～40%, intensity of illumination maintains 0.8～0.9 ten thousand lux, night and does not do requirement in 8 hours daytimes; Short 10～20 days duration root phase, newly grow plant root top and can adapt to the aquatic root system of growing in water, become the commodity plant of normal growth in nutrient solution.

Constituent and the ratio thereof of described short root phase nutrient solution are: nitrate of lime 320～360g/T, potassium nitrate 280～315g/T, magnesium sulfate 140～175g/T, ammonium phosphate 67～95g/T, iron chloride 67～88g/T, potassium iodide 0.7～1.4g/T, boric acid 0.35～0.8g/T, zinc sulphate 0.35～0.8g/T, manganese sulphate 0.35～0.8g/T, all the other add water to total amount.

Method of the present invention, through test, compare and shown following beneficial effect with conventional soil cultivation Yemen iron:

1, the time that is bred as nursery stock or commodity water planting potted landscape significantly shortens.

2, the production process of whole plant is easy to control by intelligence system, make in plant growth and development process the demand of temperature, moisture, illumination, nutrient and air all the time in optimum state, thereby realize batch production large-scale production, greatly improved labor productivity.

3, water planting plant damage by disease and insect is few, and survival rate improves greatly.

Embodiment
