Embodiment 1

[0044] (1) Seed selection: Candela seeds come from Fujian, and the collection time is from April to May every year. The first batch of precocious hypocotyls or eight or nine mature hypocotyls are collected, which have strong cold resistance and adaptability. Soak the seeds in local seawater for 1 hour and send them to the planting site as soon as possible (within 4 days). During the transportation of seedlings (that is, hypocotyls of candelabra), the tops of the seedlings are placed in the air-permeable bamboo baskets, and the bottom layer is placed with straw, which cannot be piled up, and ventilation is ensured.

[0045] (2) Transplanting: 1-2 days after the spring tide of the current month, and select cloudy days after low tide for transplanting; hypocotyls are soaked with 0.1wt%-0.2wt% potassium permanganate solution for 12h before planting, in order to sterilize. Concrete implanting method is: be that 2-3cm wooden stick is punched hole on tidal flat with diameter, the hyp...

Embodiment 2-5

[0062] Embodiment 2-5, compared with embodiment 1 except the temperature acclimation condition in step (3) domestication is different, other conditions are all the same; Specifically, embodiment 2-5 please see table 2, T represents outdoor in table 2 Please refer to Table 3 for the minimum temperature and acclimatization test results.

Embodiment 6

[0069] In this example, except that the specific steps of alternating high and low temperature domestication and cultivation of candela hypocotyls transplanted in the planting place are different from those in Example 1, other steps are the same as in Example 1. The specific steps of high and low temperature alternate domestication and cultivation in this embodiment as follows:

[0070] The first stage of acclimation step: when the minimum outdoor temperature reaches 6°C, roll up the roller blinds for low-temperature acclimation for 10 days. During this period, the minimum outdoor temperature T should be higher than 2°C; Above 10°C, domesticate for 10 days;

[0071] The second stage of acclimation step: when the minimum outdoor temperature reaches 2°C, roll up the roller blinds for low-temperature acclimation for 10 days. During this period, the minimum outdoor temperature T should be higher than 0°C; Above 8°C, domesticate for 10 days;

[0072] The third stage of acclimation ...

Abstract

The invention relates to a mangrove plant northward movement and domestication method. The method sequentially includes the following steps of firstly, collecting mangrove plant hypocotyls good in development, soaking the hypocotyls in local seawater, and transporting the hypocotyls to a planting land as soon as possible; secondly, inserting and planting the mangrove plant hypocotyls in the planting land; finally, constructing a greenhouse in the planting land before winter to ensure that tidewater can normally rise and fall in the greenhouse, and conducting high-temperature and low-temperature alternating domestication culture on the mangrove plant hypocotyls inserted and planted in the planting land. By means of the method, autumn eggplant seedlings can be domesticated under the naturalconditions, the environment temperature is continuously adjusted through the greenhouse in the seedling breeding process in winter, on one hand, the autumn eggplant seedlings are protected against theinfluences of extreme weathers, and on the other hand, the seedlings slowly adapt to the cold weather, and the adaptability to low temperature of the seedlings is improved; the seedlings are domesticated on the aspects of environment temperature, seawater salinity and soil texture, the survival rate of mangrove plants in high-latitude regions is increased, and mangrove forests can grow in high-latitude regions from 28 degrees northern latitude to 31 degrees northern latitude.

Description

technical field [0001] The present invention relates to a plant domestication and cultivation technology, specifically a method for domestication of mangrove plants to the north, especially suitable for transplanting mangrove plants candela to the north, that is, transplanting to areas with higher latitudes. The invention is suitable for other mangrove plants and belongs to the technical field of plant cultivation. Background technique [0002] Mangroves are woody plant communities naturally distributed in the intertidal zone of tropical and subtropical coasts. Since most mangrove plants are thermophilic plants, low temperature is the main factor limiting the expansion of the distribution area of ​​mangrove plants, and has a greater impact on 1-2-year-old saplings. It is generally believed that the lethal temperature of mangrove plants is -3°C. Candela is the mangrove plant with the widest natural distribution and the highest latitude in my country, and it is also one of th...
