A kind of pruning method of oil rose

Abstract

The invention discloses a pruning method of oil rose. The method comprises the following steps: 1) when the growth length of the side branches of rose plants reaches 15-20cm, performing first topping; 2) remaining about 10-15cm bud stick after the first topping; 3) when the growth length of the new buds after the first topping reaches 20-25cm, performing second branch shaping and pruning; 4) when the average number of bud sticks on each plant is 20-40 and the plant is 55-65cm high after the second branch trimming, performing third pruning on the plant with fewer than 40 bud sticks; 5) performing seedling-stage topdressing on the whole-field plants before the third pruning; 6) basically keeping over 45-50 effectively-growing bud sticks for each plant; and 7) cutting the long branches from the base. According to the method, the forming time of rose is remarkably shortened, and an ideal single-plant crown structure can be effectively formed in a short period.

Description

technical field [0001] The invention relates to a method for pruning roses for oil. Background technique [0002] Rose for oil refers to all rose varieties used for extracting rose essential oil, including: Damascus rose, centenary rose, Pingyin rose, Kushui rose, etc. This method is especially suitable for the first two oil roses. Because, in the cultivation of roses for oil, the main purpose is to increase the number of flowering branches in order to achieve the purpose of increasing flower production. [0003] But the cultivation pruning process of the oil rose of the prior art has the following defects: [0004] 1. The base branches in the lower part are too long, which is not conducive to the reasonable distribution of supporting main branches and flower branches. [0005] 2. Conventional methods do not emphasize pruning and branch control at the seedling stage, resulting in unnecessary excessively long branches and waste of nutrients. [0006] 3. Too much emphasis o...

AI Technical Summary

Problems solved by technology

[0004] 1. The base branches at the lower part are too long, which is not conducive to the reasonable distribution of supporting main branches and flower branches

[0005] 2. Conventional methods do not emphasize pruning and branch control at the seedling stage, resulting in unnecessary excessively long branches and waste of nutrients

[0006] 3. Too much emphasis on the pruning control of old and elongated branches, ignoring the reasonable control of new branches

[0007] 4. In the early stage of growth, the basic branches are kept too long, resulting in an imbalance between the upper and lower parts, and the crown shape is unreasonable

[0008] 5. Inconsistent and random pruning requirements in the early stage are not conducive to the middle and late management of plants

[0009] 6. Pruning during the whole growth period is random, resulting in uneven distribution of flower strips and reduced flower volume during the flowering period

[0010] 7. The existing crown pruning technology ignores the regulation of plant nutrition before and after pruning

[0011] 8. The pruning technique widely used now ignores the regulation of the development of the aboveground part and the underground part, resulting in a greater impact on plant development

[0012] Existing pruning methods and disorderly pruning will cause relatively large damage to plant growth, resulting in delayed plant growth and significantly reduced flower production
