Description
Technical Field
The application relates to the technical field of plant transplantation, in particular to an out-of-season seedling transplantation method by using a growth regulator to pick leaves.
Background
In order to promote the high-quality development of urban landscaping and the rapid development of urban landscaping, the greening development speed is improved mainly by tree transplantation at present. Because the time of spring and autumn is short in most places, the traditional plant planting period can not meet the construction requirement, and therefore, the out-of-season tree transplanting is particularly important.
The out-of-season transplantation per se violates the growth rule of plants, the planting difficulty is high, and the survival rate needs to be improved by adopting corresponding technical means. At present, the survival rate of transplanted seedlings is improved mainly by measures of pruning and removing leaves, controlling the size of soil balls, shading and humidifying and the like.
The Chinese patent application publication No. CN103392557A discloses an out-of-season transplanting method for big trees, which comprises the following steps: A. preparation before digging: selecting short-distance transport distance as far as possible for the seedling source; B. lifting and digging: when starting and transplanting trees, increasing the top of soil, taking the height of 6-10 times of the breast diameter of the trees as the degree, reserving more fibrous roots, and cutting off roots before transplanting large trees with the breast diameter of more than 20 cm; wrapping with straw bags, and binding with straw ropes; spraying a rooting promoter and a bactericide on the roots of the big trees; C. and (3) transportation: transportation under the condition of ensuring safety; the lifting and digging at night and the transportation are ensured in summer, and no time limitation is caused in winter; D. pruning branches and leaves: pruning the crown of the conifer to ensure that the original tree form is basically unchanged and reserving trunk branches; smearing the cut of the branch with sealing liquid; for the broad-leaved trees with few branches and leaves, the original tree form is reserved, the leaves are trimmed from the inside to the outside of the crown, the inner leaves are basically not reserved, 2/3 leaves are trimmed off from the whole tree, and main branches are reserved; E. digging a planting hole: the tree pit is cylindrical or cubic; the diameter of the tree pit is 20-30 cm larger than the specified soil ball diameter; F. hoisting: protecting the hanging point of the big tree, and selecting the position of the hanging point to be slightly above the balance point; G. transplanting and cultivating; fertilizing tree holes two days before planting seedlings, and dipping the seedlings with root-growing powder; adding 1 liter of edible vinegar with the acetic acid concentration of 3% into the conifer with the height of 5-7 m, and adding 1.5 liters of edible vinegar with the acetic acid concentration of 3% into the conifer with the height of more than 7 m; H. field planting and maintenance: watering for one time and watering for three times in a week.
Aiming at the related technologies, the inventor considers that pruning and leaf removing are the most labor-intensive links, a large amount of manpower is generally occupied for rush work before planting, the construction progress is severely restricted, and meanwhile, the plant treatment is inconsistent and branches are damaged due to human factors.
Disclosure of Invention
In order to facilitate the defoliation of the nursery stock, the application provides an out-of-season transplanting method for the nursery stock by using a growth regulator to pick off leaves.
The application provides an out-of-season transplanting method for nursery stocks by using growth regulators to pick leaves, which adopts the following technical scheme: an out-of-season transplanting method of nursery stock with leaves picked by a growth regulator 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 a plant growth regulator, and spraying the diluted plant growth regulator onto leaves of nursery stocks, wherein the plant growth regulator is mainly prepared from the following raw materials: the defoliant is at least two of polydimethylsiloxane copolyol, orange peel essential oil and soybean oil cuprammonium, and the defoliant is at least two of abscisic acid, methyl jasmonate and 2-chloroethylphosphonic acid;
(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;

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.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
