Abstract

The invention discloses a water culture method for drosera capensis. The method comprises the following steps of: selecting a robust drosera capensis seedling with the plant height between 7 centimeters and 10 centimeters, cleaning the root system of the seedling with clean water, and soaking and disinfecting the seedling with a 0.5-percent derosal solution for 15 minutes; cutting the disinfected seedling into a water culture container, and replacing nutrient fluid every five days, wherein the nutrient fluid is 1/2 Hoagland and Arnon nutrient fluid and comprises the following components: 7.3 mmol/L of total nitrogen, 1.0 mmol/L of P, 3.8 mmol/L of K, 3.0 mmol/L of Ca, 2.0 mmol/L of Mg, 89.5 mu mol/L of Fe, 46.2 mu mol/L of B, 0.8 mu mol/L of Zn, 9.1 mu mol/L of Mn, 0.3 mu mol/L of Cu and 0.1 mu mol/L of Mo; the culture temperature is between 23 DEG C and 30 DEG C; and the culture humidity is between 80 percent and 85 percent.

Description

Water culture method for drosera capensis

Technical field

The invention belongs to the Floristry field, particularly the Flower Plants in Hydroponic Culture field.

Background technology

Cape of Good Hope hair cream dish (Drosera capensis) has another name called the South Africa sundew, is a kind of tiny perennial plant, originates from South Africa.It is banded that the leaf of Cape of Good Hope hair cream dish is, and long 15 centimetres, wide 1 centimetre, the in riotous profusion tentacle of colored covers, and can secrete mucus and catch insects, and sunlight underfold pleat blazes.Early summer, Cape of Good Hope hair cream dish is left the pink flower of tiny and five lobes, and scape is up to 30 centimetres.

Cape of Good Hope hair cream dish blade is longer, and plant type stretches, and scape is long, is hydroponic flowers preferably.Cape of Good Hope hair cream dish can produce a large amount of seeds, and its breeding mainly is by seed propagation.The best matrix of cultivation Cape of Good Hope hair cream dish is sphagna, but the easy long liver moss of sphagna, affects ornamental value at contaminated environment.

Summary of the invention

The present invention is intended to overcome the defective of prior art, and a kind of water culture method for drosera capensis is provided.

Water culture method for drosera capensis is characterized in that: choosing the robust growth plant height is Cape of Good Hope hair cream dish seedling of 7～10cm, first the root system of seedling is cleaned with clear water, uses 0.5% carbendazim solution soaking disinfection 15min; Cuttage is in the water planting container after the sterilization, every 5d changes one time of nutrition liquid, described nutrient solution is 1/2Hoagland andArnon nutrient solution, its composition and content: total nitrogen content is 7.3mmol/L, other the concentrating of nutrients is P 1.0mmol/L, K 3.8mmol/L, Ca 3.0mmol/L, Mg 2.0mmol/L, Fe 89.5 μ mol/L, B 46.2 μ mol/L, Zn 0.8 μ mol/L, Mn 9.1 μ mol/L, Cu 0.3 μ mol/L, Mo 0.1 μ mol/L, condition of culture are 23～30 ℃ of temperature, humidity 80%～85%.

Described nutrient solution pH 5.2～5.6, EC 1.25～1.30.

Proportioning the best of nitrate nitrogen and ammonium attitude chlorine is 2: 1 in the described total nitrogen.

The invention has the beneficial effects as follows: the present invention has studied nitrate nitrogen and ammonium nitrogen to the impact of Cape of Good Hope hair cream dish water planting, adopts ciltivating process of the present invention, and the plant leaf stalwartness is glossy, and tentacle is full does not wilt, and pattern is bright-coloured, has higher ornamental value.

Embodiment

The experimental group experimental technique: choosing the robust growth plant height is Cape of Good Hope hair cream dish seedling of 7～10cm, first the root system of seedling is cleaned with clear water, uses 0.5% carbendazim solution soaking disinfection 15min.Cuttage is in the water planting container after the sterilization, and every 5d changes one time of nutrition liquid.Nutrient solution adopts 1/2Hoagland and Arnon nutrient solution, and total nitrogen content is 7.3mmol/L, and test arranges the proportioning of nitrate nitrogen and ammonium attitude chlorine, sees Table 1.Other the concentrating of nutrients is P 1.0mmol/L, K 3.8mmol/L, Ca 3.0mmol/L, Mg 2.0mmol/L, Fe 89.5 μ mol/L, B 46.2 μ mol/L, Zn 0.8 μ mol/L, Mn 9.1 μ mol/L, Cu 0.3 μ mol/L, Mo 0.1 μ mol/L.Nutrient solution pH 5.2～5.6, EC 1.25～1.30.Condition of culture is 23～30 ℃ of temperature, humidity 80%～85%.

The proportioning of table 1 nitrate nitrogen and ammonium attitude chlorine

Control group experimental technique: take the clear water cultivation as control group.The same experimental group of condition of culture.

Interpretation of result: water planting is observed water planting Cape of Good Hope hair cream dish upgrowth situation after 2 months, the growth indexes of mensuration comprises plant overground part dry weight, underground part dry weight, plant gross dry weight, root length.Adopt the experimental group ciltivating process obviously to be better than the control group ciltivating process.Nitrate nitrogen and ammonium nitrogen ratio are 2: 1 o'clock as can be seen from Table 1, and the gross dry weight of Cape of Good Hope hair cream dish, overground part dry weight, underground part dry weight, root length all are higher than other processing.

Table 2 experimental group and control group ciltivating process are to Cape of Good Hope hair cream dish affects on the growth
