This breed has enhanced its sustainability due to the small size of its fruit skin. The saving condition is to be placed at constant temperature for 20-25 d。
Pearl lee from long beach has been able to catch up with other plum varieties in terms of growth, budding rates and branch power, and the buds are relatively easy to form, with medium- and short-term branches accounting for the bulk of the fruits and higher yields。

3. 1 initial cultivation of peach seedlings
Dragon beach pearl lee needs to be cultivated in the selection of seedlings, transplantation and fertilization, during marriage, in the method of marriage and in post-marriage management。
The growth of plumbs is based on the choice of plumes and prunes, which are generally used more often because the slow growth of plumes does not meet the requirements for marriage at the specified time. And the rapid growth of peaches is perfectly sufficient。
The relocation and fertilization of pearl lee at long beach must be early and timely. The membrane cover keeps the peach species germinate 10-15 d ahead of the gestation time by heating up. The nursery is prepared early, fertilized, and can be replanted when the seedling grows to 2-5. The availability of pearl lee is linked to the availability of water to the root water after planting, especially in the event of drought, the number of showers needs to be changed to one in the morning and another in the evening and the number of days increased to 3-5 d. Upon living, and with a view to promoting the rapid growth of peach seedlings, the water is taken every 10 to 15 d per cent of the water from a rare dung or 0. 3 per cent urea。
The marriage of pearly lee at long beach lasted from 15 may to 15 june and from early august to the end of august. Prior to 15 may, marriage was rendered inconvenient because of the lack of thick logs; from 15 june to early august, marriage was rendered inoperable because of excessive temperatures; and after the end of august, although it was possible to live, the temperature was not the most suitable place for seeding demand, and production was slow and could affect production without enhanced management。
Dragon beach pearl lee's main method of marriage is to cut and sprout. In may and june, small sprouts were preferred, with the advantage of being simple, fast, liveable, low-cost and strong. In august, it would be appropriate to opt for cut-off, which would be a lively and fast-growing period。
Improved management is required after the marriage of pearl li at long beach. After the marriage was successful, compound fertilization was applied once. In may, the frequency of application of nitrogen fertilizer was 1 per month; in autumn, the frequency of application of urea or septic water was 15 d per second; and in october, no further fertilization was performed. The sprouts must be removed in time to untie the sprouts at 10 to 15, so as to be careful to promote the branches. Pests and pests should be detected and targeted in a timely manner。
