Optimized method for cultivating containerized seedlings of mangrove plant kandelia obovata

Abstract

The invention discloses an optimized method for cultivating containerized seedlings of mangrove plant kandelia obovate. The method mainly comprises the following steps: step (1) treatment of kandeliaobovate hypocotyls: soaking the hypocotyls with seawater in situ, then sequentially soaking with a potassium permanganate solution and a dimethoate diluent, and finally washing with tap water; step (2) selection of a seedling container: using a non-woven bag as the seedling container; step (3) preparation of culture medium: preparing the culture medium according to a volume ratio of peat soil to perlite to vermiculite equal to 3: 2: 5; step (4) containerized seedling cultivation method: inserting the hypocotyls into the seedling container containing the medium and placing in a plastic box under a plastic greenhouse to cultivate seedlings; and step (5) seedling management: watering with seawater immediately after the hypocotyls are inserted, and then watering with the tap water once a week.The method has advantages that air root-pruning is adopted to realize sturdy and prosperous seedling roots, the weight is light to facilitate transportation and realize high afforestation efficiency,the seedlings are directly transplanted together with the container to realize less damage to roots, and the non-woven bag can be self-degraded to realize no pollution to environments.

Description

technical field [0001] The invention belongs to the technical field of tree seedling cultivation, and in particular relates to a method for cultivating container seedlings of mangrove plant candelia (Kandelia obovata). Background technique [0002] Mangrove plants are evergreen shrubs or trees distributed in the tropical and subtropical coastal zones and the intertidal zone of estuaries. Because they are rich in "tannins", they are easily oxidized and turn red after being cut down, so they are called "mangroves". As a unique marine and land marginal ecosystem, mangroves play an irreplaceable and important role in providing habitat for marine animals, maintaining biodiversity, preventing coastal erosion, wind and disaster mitigation, purifying water bodies and ecotourism, so they have an important ecological significance. Significance and great economic value. [0003] Candelia (Kandelia obovata), a plant belonging to the mangrove family Candelan, is a common species in mang...

Problems solved by technology

Nutrient cup seedling raising method is more commonly used, and can provide stronger seedlings at any time, but the root system of seedlings is underdeveloped, and intertwining is easy to cause root nesting. It is also extremely difficult to carry on the tidal flat during planting, and the workload of taking out the seedlings from the nutrition cup is both large and easy to damage the roots, and the discarded nutrition cup will also cause environmental pollution and other problems
