Embodiment

Choose the kaffir lily group training Plug seedling of highly about 4cm ~ 6cm, be transplanted in 3 cun of plastic basin, spread adding ceramic and breathe freely, the every 3 cun of basin 3g of consumption routinely at the bottom of basin, mixed companion's import Osmocote, fertilising in every 70 days once.Be placed in Automatic green-house by basin seedling and cultivate, intensity of illumination is remained on 8000lux ~ 15000lux, temperature remains on 20 DEG C ~ 32 DEG C, and relative air humidity remains on 40% ~ 70%.After treating that seedling grows to 6 months, change 5 cun of basins, spray domestic No. 2, marine organisms shrimp peptide foliage fertilizer (weekly, each 200ml/ strain), seedling stage regularly wipes out spray.Cultivate after 12 months, select even, healthy and strong and without bud kaffir lily plant to carry out promoting trial.

Moved in plastic tunnel by the plant chosen, intensity of illumination is remained on 15000lux ~ 20000lux, and temperature remains on 20 DEG C ~ 32 DEG C, and relative air humidity remains on 30% ~ 60%.Adopt potassium dihydrogen phosphate and the 6-benzyl purine mixed solution of potassium dihydrogen phosphate and variable concentrations respectively, carry out promoting trial to for examination plant.Duration of test, continues to spray weekly domestic No. 2, marine organisms shrimp peptide foliage fertilizer (weekly, each 200ml/ strain).

This promoting trial designs four chemicals treatment groups and a blank group, and often organize three repetitions, each repetition 40 strain, is labeled as respectively:

A0: blank (not spraying flower forcing medicament);

A1: potassium dihydrogen phosphate (3mg/L);

A2: potassium dihydrogen phosphate (3mg/L)+6-benzyl purine (10mg/L);

A3: potassium dihydrogen phosphate (3mg/L)+6-benzyl purine (20mg/L);

A4: potassium dihydrogen phosphate (3mg/L)+6-benzyl purine (40mg/L).

Application process: foliage-spray once weekly, sprays 200ml/ strain at every turn.

At the different time of test, record the blade quantity of plant, flower bud differentiation quantity respectively, measure spray height, spray diameter (flower palm base portion) and flower palm length (flower shirttail is to the distance of spadix post), the growing way of observation plant and leaf color.

Flower forcing process is after 3 weeks, and between each group, notable difference has appearred in the growing way of plant and leaf color: the A0 control group sprayed without medicament, and bud occurs that abloom rate is low late; Flower forcing process is after 6 weeks, and between each group, notable difference has also appearred in the bud quantity of plant and growing way.Result of the test refers to table 1 to table 2.

What the process of table 1 different agents grew kaffir lily blade quantity affects unit: sheet

Process	2nd week	4th week	6th week	9th week	Remarks
						A0	7	9	11	13	Blade lacks brightness, and yellow is serious
A1	7	10	13	15	Blade has light, but has aetiolation
						A2	8	11	14	17	Blade is glossy, and growth is normal
A3	8	12	15	19	Blade light is dark green, robust plant, attractive in appearance
						A4	7	13	16	21	Newborn blade is little, plant strain growth deformity

the process of table 2 different agents affects unit to kaffir lily flower bud differentiation: individual

As can be seen from table 1 and table 2, working concentration is that the potassium dihydrogen phosphate (A1 medicament group) of 3mg/L carries out flower forcing process to kaffir lily, the upgrowth situation of plant is very good relative to the upgrowth situation of A0 control group plant, its bloom number and number of blade are apparently higher than the plant of A0 control group, bud is healthy and strong simultaneously, and blade is glossy.This shows, potassium dihydrogen phosphate is bloomed to kaffir lily and had facilitation, can improve the appreciation effect of kaffir lily plant.

It can also be seen that, by the 6-benzyl purine of variable concentrations and potassium dihydrogen phosphate use in conjunction, to the potted flower commodity rate of kaffir lily, to there is good facilitation from table 1 and table 2.Wherein, the effect of A3 medicament group (i.e. potassium dihydrogen phosphate 3mg/L+6-benzyl purine 20mg/L) is best, plant flower bud differentiation early, many, add plant leaf quantity, there is best growth conditions in whole strain simultaneously.But, when the concentration of 6-benzyl purine is up to 40mg/L, start the normal growth suppressing seedling, occur the deformities such as short and small, the newborn blade of bud is little.As can be seen here, the 6-benzyl purine of debita spissitudo has good flower forcing effect to kaffir lily.In addition, the kaffir lily plant leaf through the process of 6-benzyl purine is dark green, and yellowing leaf number is starkly lower than other medicament group, and this shows, 6-benzyl purine has certain inhibitory action to kaffir lily yellowing leaf.

The growth conditions of kaffir lily spray is the most important index of potted flower ornamental value.Use potassium dihydrogen phosphate and the spray growth of 6-benzyl purine to kaffir lily to have good facilitation, its early flowering can be promoted.Utilize 6-benzyl purine and potassium dihydrogen phosphate use in conjunction, the growth result of kaffir lily spray is apparently higher than being used alone potassium dihydrogen phosphate, wherein best with the effect of A3 medicament group (i.e. potassium dihydrogen phosphate 3mg/L+6-benzyl purine 20mg/L), bud abloom rate is up to 90%, spray is many, long and sturdy, spend facies palmaris long-pending large simultaneously, significantly improve the ornamental value of kaffir lily plant.

In sum, spray separately potassium dihydrogen phosphate on kaffir lily blade face or spray potassium dihydrogen phosphate and 6-benzyl purine mixed solution, all can impel kaffir lily plantlet in vitro early flowering, and its abloom rate and cut-flower quality can be improved, improve the ornamental value of kaffir lily plant.
