Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific examples.

[0009] A kind of cultivation technology of Mandshurica mandshurica, the cultivation method is realized by adopting the following steps.

[0010] (1) Seed treatment: The seeds of Mandshurica mandshurica belong to long-dormant seeds, and they need to be germinated before they emerge. Accelerate germination, dig pits and bury them in layers. Take out the seeds before sowing in the next spring. It is found that most of the seed embryos have turned yellow-green, and a small amount of germination can be sown in time. ②Variable temperature treatment method: Newly collected seeds in mid-to-late September need to be treated with variable temperature indoors, mixed evenly according to the ratio of 1:3 of seed and sand, first treated at 20-24°C for two months, and then turned to cold temperature Treatment, at 0-5°C for two months, the order of treatment cannot be reversed, and the time ...

Abstract

The invention discloses a cultivation technique for Fraxinus mandshurica. The cultivation technique is realized by adopting the following steps: (1) seed treatment: a step of accelerating germination since Fraxinus mandshurica seeds are seeds with a long dormancy period and can sprout only after germination acceleration, wherein common methods for germination acceleration comprise A, an over-winter stratification burial-storage method, and B, a temperature-varying treatment method; (2) seeding: a step of carrying out seeding in spring, carrying out full watering after seeding and carrying out timely chemical weeding before seedling emergence, wherein 0.5 to 0.7 kg of base fertilizer is applied per hectare while soil is turned up, and during ridge cropping, the seeding rate per mu is 35 to 40 grams and the thickness of covering soil is 1 to 2 cm; and (3) management in a seedling stage: a step of strengthening nutrient and water management, digging out Fraxinus mandshurica seedlings in autumn when the seedlings grow to a height of 20 to 30 centimeters in the year, temporarily planting the Fraxinus mandshurica seedlings for overwintering when temperature is stable and ground temperature drops to below 0 DEG C, digging out the temporarily-planted Fraxinus mandshurica seedlings and planting the seedlings in a mountain in mid-to-late April in spring, and carrying out timely soil-thawing afforestation since Fraxinus mandshurica has a rejuvenation period of about 20 days.

Description

[0001] technical field [0002] The invention relates to a cultivation method, in particular to a cultivation technique of Mandshurica mandshurica, belonging to the field of agricultural cultivation methods. Background technique [0003] Fraxinus ash is mainly produced in Northeast China and North China. Yellowish-white (sapwood) or brownish-yellow (heartwood). The annual rings are obvious but not uniform, the wood structure is thick, the texture is straight, the pattern is beautiful, shiny and hard. Fraxinus mandshurica has the characteristics of elasticity, good toughness, wear resistance and moisture resistance. But it is difficult to dry and easy to warp. Workability is good, but tearing should be prevented. The cut surface is smooth, painted, and relatively viscous. Contents of the invention [0004] The present invention is based on the existing cultivation method of Fraxinus Fraxinus and adopts innovative scientific principles to propose a cultivation techniqu...
