Description
Technical field
The present invention relates to water culture technical field, particularly one fragrant camphor tree seedling water culture technology.
Technical background
Fragrant camphor tree is aiphyllium, and tree crown is extensively opened up, and is thick with leaves, spectacular, is excellent street tree and shade tree, have that very strong smoking lays the dust, water conservation, solid native sand prevention and the ability of beautifying the environment, be one of main green tree species of China.Camphor tree happiness warm and moist weather, cold resistance is not strong, more water-fast wet, but not drought-resistant, barren and saline-alkali soil, easily there is iron deficiency disease disease when China's northern territory cultivation.Thus fragrant camphor tree Salt And Alkali Tolerance breeding of new variety and the fragrant camphor tree seedling salinity and alkalinity resistance of raising are study hotspots in recent years, wherein camphortree root ties up to Growth trends and Nutrient Absorption mechanism thereof under saline and alkaline condition is the key issue that need solve, but under conventional pot-culture method experimental condition, camphortree root system subject to damage, restoration ecosystem is slow, easy aging death, has a strong impact on accuracy and the specific aim of result of study.
Summary of the invention
The present invention is directed to the problem in background technology, have studied a kind of fragrant camphor tree seedling water culture technology, strictly can control the nutrient environment condition of fragrant camphor tree growth, cost is lower, can not root system be damaged again simultaneously, also be convenient to observe root growth behavioral characteristics, greatly improve accuracy and the specific aim of result of the test.
The technology of the present invention solution:
Fragrant camphor tree seedling water culture technology mainly comprises the following steps:
(1) seedling prepares
Choose the annual fragrant camphor tree seedling of normal growth, wash away except rhizosphere soil with flowing water, cut off main root, main root length is made to be no more than 10cm, do not damage side root, overground part retains grown on top gesture more weak side shoot 2-3, wipes out all the other strong prosperous side shoot and bottom blades, immediately seedlings root is put into 200mg/LIAA(heteroauxin) solution soaks 5-8 minute.
(2) compounding
According to nutrient solution prescription standard, prepare macroelement 20 times of mother liquors and microelement nutritious liquid 100 times of mother liquors respectively, each compound requires as analyzing pure.
(3) container prepares
Water planting glass container or plastics transferring box is selected according to seedling size and test requirements document.
(4) nursery stock transplanting
After cultivating container running water is cleaned up, be placed in cool canopy or glass greenhouse, first add 2/3 regulation tap water volume, then according to cultivating container regulation nutrient solution volume size, by the Standard entertion macroelement mother liquor of 25ml/L, micro-mother liquor is added again by the standard of 5ml/L, stir while adding, prevent precipitation, finally add running water to ormal weight, nutrient solution ultimate density is 0.5 dosage (i.e. 0.5 times of standard formula consumption), liquid level distance water planting bottleneck or transferring box end face 2-3cm, seedling is put into culture vessel rapidly, make seedling 2-3cm root system higher than nutrition liquid level, be exposed in air, automatic oxygenation pump is put into water planting container, ensure oxygenation in 24 hours, finally fix with cobble or sponge.
(5) nutrient management
Within every 3-5 days, measure the electrical conductivity of nutrient solution in container with conductivity meter, and according to the nutrient solution dosage of running water preparation and the relation regression equation y=0.011x of electrical conductivity
3-0.0742x
2+ 0.6111x-0.3722(R2=0.9999, wherein y is nutrient solution dosage, and x is conductivity value, and the scope of application is 0-2 dosage) show that fragrant camphor tree seedling is to the absorbing state of nutrient in nutrient solution.(R2 refers to the goodness of fit of this regression equation to nutrient solution dosage and conductivity relation, after namely measuring electrical conductivity, calculates by changing equation the similarity that the nutrient solution dosage that obtains and true nutrient solution dosage have 99.99%).Within every 3-5 days, adopt acidometer to detect the change of nutrient solution pH value, regulate nutrient solution pH value to remain between 6.5-7.0 with HCL or 0.1mol/LNaOH of 0.1mol/L; Observation battalion's nutrient solution water surface change in every 3-5 days, remains that the nutrient solution water surface does not reduce; Monthly clean a water planting container, prevent nutrient solution to be subject to pathogen contamination.
(6) nursery stock management
Seedling preculture, after 7 days, is cultivated under moving on to outdoor normal lighting conditions from cool canopy or greenhouse, within every 3-5 days, observes seedling growth, prevents the insect pest impacts such as snail, immediate removal perish root system.When growth of seedling is to 60-70cm, support immediately need be set up to prevent lodging, if when rainy day or other bad weather, seedling must be moved in greenhouse.
After having tested, the standard that residue seedling presses seeding row spacing 50-60cm is transplanted to field, applies fertilizer by the standard of 1kg/L before transplanting, and suitably prune, remove side shoot and Partial mature blade, ensure that nursery stock recovers rapidly and normal growth.
Further, in described step (3), plastics transferring box is high density PVC hardboard or plastic foam plate.
Further, described step (6) medium-height trestle is cube, is made up of the bamboo pole of diameter 1-1.5cm.
Beneficial effect of the present invention:
This method innovation is to adopt water culture, and according to the nutrient solution dosage of North Jiangsu Area running water preparation and the relation formula y=0.011x of electrical conductivity
3-0.0742x
2+ 0.6111x-0.3722 show that fragrant camphor tree seedling is to the absorbing state of nutrient in nutrient solution, strictly can control the nutrient environment condition of fragrant camphor tree growth, cost is lower, can not damage root system again simultaneously, also be convenient to observe root growth behavioral characteristics, greatly improve accuracy and the specific aim of result of the test.
