[0003] The object of the present invention is to provide a kind of method for outdoor hydroponic rooting of rubber tree test-tube seedlings, take the rubber tree test-tube seedlings of 3.5-5.5cm as test material, adopt IBA auxin to process under 0-1.5mg / L, and transplant It overcomes the disadvantages of the prior art, such as the rooting induction of test tube seedlings and the complicated work procedures, heavy workload and high production costs in the process of hardening and transplanting.

Embodiment 1

[0016] Four treatments and three repeated auxin concentration single-factor outdoor hydroponic rooting induction experiments were carried out on rubber tree plantlets in test tubes. The medium in the culture chamber induced rooting as a control. According to the temperature level and the amount of water in the square plate of water, the amount of tap water evaporated in the culture medium should be supplemented in time, that is, when the culture medium is lower than 1 / 3 of the stem section of the rubber tree test tube seedling in the square plate, tap water should be replenished in time, and every 3- 7. Replace the reclaimed water in the four treatments, keep the IBA concentration unchanged from the test design concentration, and ensure the water quality is clean.

[0017] After 2-3 days of cultivation, the stems of test tube seedlings inserted into solutions containing different IBA concentrations began to appear white spots, forming root bases; the first-order roots grew fro...

Abstract

The invention provides a method for outdoor hydroponic rooting of rubber tree test-tube seedlings. Rooting induction and seedling hardening are completed in one step. Specifically, when the culture solution is lower than 1 / 3 of the stem section of rubber tree test-tube seedlings in the square plate, tap water is replenished in time. In 3 to 7 days, the auxin IBA in the culture solution of rubber tree test-tube seedlings was replaced, and the concentration of the culture solution in the test was kept constant. The outdoor hydroponic rooting of the rubber tree is about 20 days shorter than the conventional tissue culture rooting. The rooting of rubber tree test-tube seedlings through hydroponics can reduce the work of medium preparation, indoor aseptic inoculation, culture room cultivation, seedling hardening and transplanting.

Description

technical field [0001] The invention relates to a method for outdoor hydroponic rooting of test-tube seedlings of rubber trees, which completes rooting induction and seedling hardening in one step, thereby reducing the processes of strengthening seedlings in a laboratory, rooting induction, and outdoor hardening of seedlings. Background technique [0002] Rubber tree Moraceae Ficus is an evergreen shade-tolerant woody plant, native to India and Malaysia, because of its wide leathery leaves and high ornamental value, it is deeply loved by people and is a famous indoor foliage and landscaping tree species. Indoor rooting of rubber trees needs to go through work such as strong seedling cultivation, rooting induction, hardening and transplanting, and rooting induction needs to carry out routine procedures such as medium preparation, sterilization, inoculation, and cultivation in the cultivation room; Seedlings and cleaning the root medium of the plant are cumbersome and easy to ...
