Hydroponic technology for Cinnamomum camphora seedlings

Abstract

The invention discloses a hydroponic technology for Cinnamomum camphora seedlings, the technology mainly comprising following steps: (1) preparation of seedlings; (2) preparation of a nutrient solution; (3) preparation of containers; (4) transplantation of seedlings; (5) management of the nutrient solution; (6) management of seedlings. The hydroponic technology is innovative in that: the hydroponic method is adopted; the nutrient absorption of Cinnamomum camphora seedlings is deduced by a relation formula between the dosage of the nutrient solution and the conductivity, wherein the nutrient solution is prepared from tap water of northern Jiangsu, and the relation formula is y=0.011x<3>-0.0742x<2>+0.6111x-0.3722. By use of the hydroponic technology, nutritional environment conditions for Cinnamomum camphora growth are strictly controlled; the cost is low; root systems will not be harmed; the dynamic characteristic of root system growth is easy to observe; the accuracy and pertinence of test results are greatly increased.

Description

technical field [0001] The invention relates to the field of plant hydroponic technology, in particular to a hydroponic technology of camphor seedlings. technical background [0002] Camphor is an evergreen tree with a wide crown, dense branches and leaves, and majestic momentum. It is an excellent street tree and shade tree. One of the green tree species. Camphor tree likes warm and humid climate, not strong cold resistance, more resistant to water and humidity, but not resistant to drought, barren and saline-alkali soil, it is prone to iron deficiency chlorosis when cultivated in northern my country. Therefore, the breeding of new saline-alkali-resistant varieties of Cinnamomum camphora and the improvement of saline-alkali resistance of Cinnamomum camphora seedlings are research hotspots in recent years, among which the growth dynamics of Cinnamomum camphora root system under saline-alkali conditions and the mechanism of nutrient absorption are key issues to be solved.

Camphor tree likes warm and humid climate, not strong cold resistance, more resistant to water and humidity, but not resistant to drought, barren and saline-alkali soil, it is prone to iron deficiency chlorosis when cultivated in northern my country

Therefore, the breeding of new saline-alkali-resistant varieties of Cinnamomum camphora and the improvement of saline-alkali resistance of Cinnamomum camphora seedlings are research hotspots in recent years, among which the growth dynamics of Cinnamomum camphora root system under saline-alkali conditions and the mechanism of nutrient absorption are key issues to be solved. However, under the test conditions of the conventional pot method, the root system of Cinnamomum camphora is easily damaged, the recovery growth is slow, and it is easy to age and die, which seriously affects the accuracy and pertinence of the research results.
