Embodiment 1

[0034] In autumn, choose sandy soil with flat terrain, good ventilation, rich in humus, and a pH value of 4.7 to 6.2. Level the land, plow it deeply and finely with a rake, and plow the soil to a depth of 25 cm. While turning the ground, evenly sprinkle 50 kg / ha of trichlorfon, 37.5 kg / ha of 65% zinc zinc wettable powder, and 300 kg / ha of ferrous sulfate with 400 times liquid; . The height of the bed is 15 cm, the width of the bed is 1.2 meters, and the walkway between the beds is 0.4 meters wide. Disinfect the river sand with trichlorfon, 65% zinc wettable powder and 400 times liquid ferrous sulfate, mix the disinfected river sand and soil in a volume ratio of 1:1 and spread it on the bed 10 cm thick and compacted.

[0035] In mid-August, the selected wild Changbai pine seeds were stuffed with carbendazim powder for 24 hours, and then soaked in water for 24 hours. After water selection to remove impurities, 0.3% formalin Disinfect the seeds. Afterwards, mix the seeds and ...

Abstract

The invention discloses an artificial breeding method for wild pinus sylvestriformis, belonging to the technical field of plant planting. The artificial breeding method comprises the following steps of: firstly, preparing a nursery bed; selecting sandy loam land or lightly-sticky soil land with flat round, favorable ventilation, abundant humic matters and the pH value of 4.7-6.2, preferable sandyloam old ginseng land or lightly-sticky soil old ginseng land on which ginseng is planted; secondly, treating seeds including stacking at normal temperature and seed germination acceleration; thirdly, sowing: uniformly spreading pinus sylvestriformis seeds with the split rate of 80-90 percent on the nursery bed; fourthly, managing the nursery bed; fifthly, managing reserved bed seedlings; and sixthly, outplanting nursery stock. The invention has the benefits that the germination percentage is increased from 55 percent before treatment to over 80 percent after treatment; and the emergence rateis increased from 40 percent before treatment to over 85 percent after treatment. The bred pinus sylvestriform stock has the advantages of robust growth, vivid green color, strong resistance and finevariety.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to an artificial breeding method of wild pine trees. technical background [0002] Changbai pine is an evergreen tree that grows in Changbai Mountain. It is a unique and rare tree species in Changbai Mountain. It is a national first-class key protected wild plant. Changbai pine tree is 25-30 meters high, 25-40 cm in diameter, the crown is oval or flat oval, triangular or umbrella-shaped, the bark of the lower part of the trunk is brown, deeply cracked, and the lobes are irregular rectangles, the upper part is brownish yellow to reddish yellow, Flaky exfoliation, slightly recurved. Changbai pine is known as the beauty pine because of its beautiful tree shape. It has ornamental value and is an excellent tree species for urban beautification. However, due to the low reproduction and survival rate of wild Changbai pine in the natural state, coupled with human-destru...
