Problems solved by technology

[0006] Conventional anti-cold and anti-freeze measures include building a cold-proof shed and adding a layer of straw or thatch to the seedling tip. Although this measure can start from the outside of the seedlings and have a certain effect of resisting frost and severe cold, the anti-freezing effect is not significant.

Embodiment 1

[0021] A method for preventing overwintering seedlings of camphor camphora seedlings from direct seeding in the field from freezing damage, including two steps of controlling seedling height growth during late summer and early autumn and antifreezing treatment before frost. Spraying the overwintering seedlings of monkey camphor seedlings directly in the field with the mixed liquid of 0.2% chlormequat and 2% potassium dihydrogen phosphate for the first time. The purpose of this treatment is to control the high growth of seedlings and promote the lignification of seedlings. Form strong and full terminal buds; the second step is specifically: in the middle and late November, spray the overwintering seedlings of monkey camphor seedlings for the second time with a medicinal solution containing 0.0001% S-induced antibiotics in the field to improve the quality of overwintering seedlings. Intrinsic cold and frost resistance, and at the same time build a transparent plastic film shed be...

Embodiment 2

[0024] A method for preventing the overwintering of monkey camphor annual container seedlings from freezing damage, including two steps of controlling the growth of seedlings during late summer and early autumn and antifreezing treatment before frost. The mixed solution of % S-induced antibiotic and 1% potassium dihydrogen phosphate is sprayed for the first time on the annual container seedlings of monkey camphor. The purpose of this treatment is to control the high growth of seedlings, promote the lignification of seedlings, and form a strong and plump The second step is specifically: in the middle and late November, spray the annual container seedlings of Cinnamomum camphora live-seeded in the field for the second time with a medicinal solution containing 0.0005% S-induced antibiotics, so as to improve the intrinsic resistance of overwintering seedlings. Cold and frost resistance, at the same time, build a shed of transparent plastic film + straw curtains before frost, extern...

Embodiment 3

[0027] A method for preventing annual bagged container seedlings of Cinnamomum camphora from overwintering from freezing damage, including two steps of controlling seedling height growth during late summer and early autumn and antifreezing treatment before frost. The first step is specifically: cutting roots in mid-September The method is to control the absorption of water and nitrogen nutrients by the seedlings, and at the same time increase the application of potassium fertilizer in the first ten days of September, apply 15 kg of potassium chloride per mu, and spray the leaves with a 2% potassium dihydrogen phosphate solution by mass ratio, so that the seedlings can The concentration of cell fluid increases and the amount of dry matter increases. The second step is specifically as follows: in the middle and late November, the annual bagged container seedlings of monkey camphor camphora are sprayed for the second time with a medicinal solution containing 0.001% S-induced antib...

Abstract

The invention relates to the field of forestry and horticulture, in particular to a method for preventing freezing of overwintering cinnamomum bodinieri seedlings. The invention comprises the steps of S1, conducting seedling height growth control treatment during summer end and early autumn, S2, conducting anti-freezing treatment before frost descent, during the period between the summer end and early autumn applying medicinal solution containing one or more of S-inducer resistance, cycogan and paclobutrazol to conduct spraying treatment to the seedlings, or conducting root cutting treatment to effectively control the height growth of the cinnamomum bodinieri seedlings, promote the lignification of cinnamomum bodinieri seedlings and enhance the anti-freezing ability of overwintering cinnamomum bodinieri seedlings; before frost descent using medicinal solution containing S-inducer resistance to conduct spraying treatment to the overwintering cinnamomum bodinieri seedlings to effectively enhance the anti-freezing capability of the overwintering cinnamomum bodinieri seedlings, at the same time, with the combination of externally erected anti-freezing shed and other measures, the freezing disasters of the overwintering cinnamomum bodinieri seedlings caused by the frost, snow, cold wave and low temperature can be avoided, and the commercial passing rate of the cinnamomum bodinieri seedlings is substantially increased.

Description

technical field [0001] The invention belongs to the field of agriculture, forestry and gardening, and in particular relates to a method for preventing overwintering seedlings of monkey camphor seedlings from freezing damage. Background technique [0002] With the structural adjustment of forest species and afforestation tree species in southern forest regions of my country, the market demand for high-quality precious timber, medicinal, fruit and fine ornamental evergreen broad-leaved tree species continues to increase. Monkey camphor (Cinnamumumbodini eilevl) is a plant of the genus Lauraceae, commonly known as big-leaf camphor, a large evergreen tree with a height of up to 20m and a diameter at breast height of 80-100cm. It is the main tree species of evergreen broad-leaved forests in subtropical regions of my country. Distributed in Yunnan, Guizhou, Sichuan, Hubei, Hunan and other provinces. It is naturally distributed in mountains with an altitude of 400-1300cm, and often...
