Embodiment 1

[0031] A new method for cultivating Paulownia saplings, comprising the following steps:

[0032] S1, nutrient matrix selection, ratio and treatment:

[0033] Mix 40% of the matrix yellow mud, 30% of coconut bran, 15% of perlite and 15% of complex nutrients by mass percentage, and then put them into a black plastic matrix cup with a size of 14cm×16cm; the complex nutrients include urea, phosphoric acid dibasic Potassium hydrogen, potassium sulfate, trace elements calcium, magnesium, zinc, copper, iron soluble compounds and alanine, arginine, cystine, glycine, lysine and proline.

[0034] S2. Seed root collection:

[0035] Choose a young root with a diameter of 8mm. When digging the root, dig out the more complete root as much as possible to facilitate the identification of the upper and lower ends of the root. Dig back and then cut it into a 7cm root segment, and leave it indoors for 5 days to let it lose water naturally. The moisture content of the seed root is 10%;

Embodiment 2

[0043] A new method for cultivating Paulownia saplings, comprising the following steps:

[0044] S1, nutrient matrix selection, ratio and treatment:

[0045] Mix 50% of the matrix yellow mud, 40% of coconut bran, 5% of perlite and 5% of complex nutrients, and then put them into a black plastic matrix cup with a size of 14cm×16cm; the complex nutrients include urea, phosphate dibasic Potassium hydrogen, potassium sulfate, trace elements calcium, magnesium, zinc, copper, iron soluble compounds and alanine, arginine, cystine, glycine, lysine and proline.

[0046] S2. Seed root collection:

[0047] Choose young roots with a diameter of 5mm. When digging the roots, dig out the more complete roots as much as possible to facilitate the identification of the upper and lower ends of the roots. After digging back, cut them into 6cm root segments and place them indoors for 4 days to let them lose water naturally. The moisture content of the seed root is 10%;

Abstract

The invention discloses a new cultivation method of paulownia seedlings. The method includes following steps: S1, selecting, proportioning and treating a nutritional matrix; S2, collecting seed roots;S3, burying the roots; S4, cultivating, hardening seedlings, and transplanting, wherein compound nutrients include nitrogen, phosphorus and potassium elements, trace elements and compound amino acid,the nitrogen element is urea, the phosphorus element is potassium dihydrogen phosphate, the potassium element is potassium sulfate, the trace elements include calcium, magnesium, zinc, copper and iron which are added in a soluble compound form, and the compound amino acid is composed of alanine, arginine, cystine, glycine, lysine and proline. A standardized cultivation greenhouse and a standardized treatment process are adopted, so that a farming method of field cultivation is broken through, occupied area is reduced, lesion probability of the paulownia seedlings is lowered, seedling cultureperiod is shortened, and yield is increased.

Description

technical field [0001] The invention relates to the technical field of forest tree planting, in particular to a new method for cultivating Paulownia saplings. Background technique [0002] Paulownia tree is the collective name for Paulownia tomentosa of the genus Paulownia of the family Scrophulariaceae. It belongs to a total of 7 species of deciduous trees, all of which are produced in my country. Except for the northern northeast, Inner Mongolia, northern Xinjiang, Tibet and other regions, they are distributed throughout the country, cultivated or wild, and are being introduced in some areas. White-flowered Paulownia is also distributed in Vietnam and Laos, and some species have been introduced and cultivated in many countries on all continents of the world, mainly using its wood. my country has a complete population of Paulownia genus, which provides favorable conditions for breeding improved varieties and realizing the production of improved varieties of Paulownia. Pau...
