Comparative example

The seedling out-of-season transplanting method for picking leaves by using the growth regulator in the comparative example comprises the following steps:

(1) treating the nursery stock before transplanting: cutting off roots of the seedlings, and uniformly spraying a transpiration inhibitor on the plants; diluting abscisic acid by 2000 times, and spraying the abscisic acid on nursery stocks, wherein the spraying amount of the nursery stocks is 1kg per plant;

(2) seedling digging and hoisting: digging a detection ditch in advance before digging, removing floating soil in the range of soil balls around the root of the tree body, digging outwards the soil balls, flattening after digging, tightly wrapping with a straw rope, and then hoisting;

(3) transplanting the nursery stock: after soil is loosened, organic fertilizer is added, then the soil is moistened by water and is stirred uniformly for later use, so that the improvement of the planting soil is realized; then digging a tree pit, wherein the diameter of the tree pit is 50cm larger than that of the soil ball, the depth of the tree pit is deepened to 40cm, and meanwhile, an operation ditch of 40cm is reserved on each side; then installing a vent pipe, uniformly perforating holes on the diameter of the PVC pipe, wrapping the PVC pipe by using a shading net, placing the PVC pipe around the soil ball, and placing the nursery stock in a tree pit; then adding backfill into the tree pits for landfill; (ii) a

(4) And (3) nursery stock maintenance: fixing the nursery stock; watering; then winding the base of the tree body by using a straw rope; and (3) diluting 20g of nutrient solution by 2000 times, and drilling and conveying.

Performance test

Detection method fallen leaf detection: selecting tree leaves of the seedlings, spraying the diluted plant growth regulator, applying for 1 and 2 weeks, wherein the defoliation condition of the seedlings is shown in table 4, the defoliation condition of the seedlings is expressed by defoliation rate, and the defoliation rate is calculated according to the following formula.

Defoliation rate is 100% of total defoliation/total spray

Detecting the survival condition of the nursery stock: the total number of transplanted seedlings is 500, the survival condition of the seedlings is shown in table 4, the survival condition of the seedlings is expressed by the survival rate, and the survival rate is calculated according to the following formula.

Survival rate is the number of surviving nursery stocks/500 x 100%

TABLE 4 examples 1-22 and comparative examples the defoliation rate and survival rate of seedlings

Combining example 1 and comparative example 1, and combining table 4, it can be seen that the effect of defoliating by using abscisic acid alone as a defoliant is poor compared with the effect of combining the defoliant and an auxiliary agent, and the survival rate of the nursery stock is obviously increased compared with that of the single defoliant.

By combining examples 1-5 and table 4, it can be seen that adjusting the raw material ratios of the components in the plant growth regulator has a greater effect on the defoliation of the nursery stock, the defoliation efficiency increases with the gradual increase of the ratio of the defoliant to the adjuvant, and the survival rate also increases, and when the ratio of the defoliant to the adjuvant continues to increase, the defoliation effect is reduced, the survival rate of nursery stock transplantation is also reduced, the ratios of the components in the nutrient solution also affect the survival rate of the nursery stock, and when the amount of rooting powder and urea in the nutrient solution is proper, the survival rate of nursery stock transplantation is increased.

By combining examples 5-18 and table 4, it can be seen that the defoliation condition of the nursery stock and the survival condition of the nursery stock are affected by adjusting the proportion of each component in the defoliant, wherein abscisic acid and 2-chloroethylphosphonic acid are cooperated with each other to greatly affect the nursery stock, and then the proportion of each component in the auxiliary agent is adjusted, so that the influence of the defoliant on the defoliation condition of the nursery stock is further increased, and the survival rate of the nursery stock is improved.

In combination with examples 18 to 22 and table 4, it can be seen that the number of spraying times and the amount of spraying of the plant growth regulator also have a certain influence on the seedling leaf falling condition, and the plant growth regulator is more uniformly distributed on the seedlings through a plurality of times of spraying a small amount of the plant growth regulator, so that the seedling leaf falling condition is better.
