Problems solved by technology

[0002] At present, in Sichuan and Guizhou, according to the conventional method of overwintering the poinciana seedlings in the open field, the method of spraying the stems and leaves with antifreeze is usually used, but even if the stems and leaves are sprayed with antifreeze, most or all of the poinciana seedlings will die, and some may even die. Seedlings with a height of 1 to 2 meters may also die

Embodiment 1

[0009] A method for overwintering poinciana seedlings. Choose a place with leeward and sunny, flat terrain, and deep sandy loam to plant poinciana seedlings. In spring, transplant seedlings when they grow to 20-30cm. The distance between plants and rows is 50cm*50cm, and the drainage ditch Width 20cm, depth 30cm should keep the drainage unobstructed and no water accumulation; use Shenggenbao 1000 times solution to irrigate the roots, according to the plant size and soil, each plant should be irrigated with 1000 times solution of Shenggenbao 1000-2000ml, and the soil within the root system should be thoroughly irrigated. Induce the growth of the root system and promote the survival of the plants; 25-30 days after the seedlings are transplanted, the first fertilization is carried out after the seedlings are confirmed to be alive, and the dilute liquid fertilizer of 1000 times potassium dihydrogen phosphate + 2000 times urea is used, and the fertilization is not directly applied on...

Abstract

The invention discloses an overwintering method for plantlets of delonix regia. In the growing seasons, rooting hormones are used for promoting a plant root system to be more developed and improving the resistance of plants so that the plants can get prepared for resisting the cold in winter; comprehensive cultivation technical measures including fertilization, watering, trimming, seedling hardening and the like are taken to promote normal growth and the autumn lignification process of nursery stock and improve the cold resistance of the nursery stock; winter cold resistance measures are taken to strengthen the overwintering ability of the nursery stock. Through comprehensive application of the technical measures, the overwintering death rate of the plantlets of the delonix regia is greatly lowered.

Description

technical field [0001] The invention relates to a method for overwintering young tree seedlings, in particular to a method for overwintering young poinciana seedlings. Background technique [0002] At present, in Sichuan and Guizhou, according to the conventional method of overwintering the poinciana seedlings in the open field, the method of spraying the stems and leaves with antifreeze is usually used, but even if the stems and leaves are sprayed with antifreeze, most or all of the poinciana seedlings will die, and some may even die. Seedlings with a height of 1 to 2 meters may also die. Contents of the invention [0003] The invention provides a method for overwintering young poinciana seedlings to solve the deficiencies in the prior art. [0004] The object of the present invention is achieved like this: a kind of overwintering method of poinciana seedling, selects the place of the leeward facing sun, gentle terrain, deep sandy loam soil to plant poinciana seedling, i...
