Description

Cuttage technology optimization-based efficient cultivation method for container seedlings of sequoia intermedia
Technical Field
The invention belongs to the technical field of cuttage seedling raising of sequoia intermedia, and particularly relates to an efficient container seedling raising method of sequoia intermedia based on cuttage technology optimization.
Background
The sequoia intermedia is a general name of excellent hybrid clone of the genus elytea, the plant research institute of Chinese academy of sciences of Jiangsu province carries out introduction and hybrid breeding work of the genus elytea from 1973, and 8 new species of national plants and 10 improved species of national and provincial trees are obtained so far. The popularization items of the China fir 302 and the China fir 401 are selected as one of 100 national forestry science and technology popularization achievements by the national forestry department in 1997. The taxus chinensis has the advantages of fast growth, water-moisture resistance, salt and alkali resistance, good material quality, beautiful landscape and the like, and has wide application prospect and huge market demand in lake wetlands, water nets, mudflats and plain greening forests in Yangtze river basins, southeast coastal areas and inland areas of China. The seedling breeding and industrialization of the sequoia zhongshanensis are gradually emphasized in suitable habitat areas of China, 8 sequoia zhongshanensis breeding nursery gardens with the area of more than 6000 mu are established in provinces such as Jiangsu, Zhejiang, Anhui, Hubei, Chongqing, Yunnan and the like in Yangtze river basin of China at present, and 1 fine variety base of China-level sequoia zhongshanensis forest is established. 3000 more than ten thousand high-quality seedlings are produced and popularized in an accumulated way, and the economic value is about 30.8 hundred million yuan.
In order to improve the transplanting survival rate of 1-year-old cutting seedlings, improve the commercialization benefit of seedling cultivation and improve the transplanting survival rate of the yew seedlings after being outplanted, container seedling cultivation is a method frequently adopted by the yew seedling cultivation, the cultivation of the yew container seedlings is applied in the production process of seedlings in the young period of less than 3 years, the technical process is that 1-year-old cutting seedlings obtained through soft branch cutting are filled into pots in the next spring for container seedling cultivation, the containers with proper specifications and sizes are replaced again along with the growth of the seedlings, the annual growth amount of the common container seedlings is about 50-80 cm, 3-year-old container seedlings with the height of 150-200 cm can be obtained through cultivation in two years after filling into the pots, and the container seedlings can be directly used for afforestation application or further cultivation of large-size seedlings. Light-control soft branch fog cutting is a main method for seedling breeding of the taxus chinensis, and facilities such as a cutting bed, a micro-spraying system, a sunshade and the like need to be built, and a cutting matrix with proper physicochemical characteristics is prepared. In order to ensure the emergence rate in production, the conventional cutting bed type cutting method generally has the number of cutting slips per square meter of about 500 plants, and some production enterprises even have higher cutting density of 700 plants or more. After the cutting survival in 8-9 months, newly-germinated branches on the cutting grow faster, and because the cutting density is high, the ventilation of the growing environment of the cutting seedlings is extremely poor, and the cutting seedlings are easy to generate fungal diseases such as red blight, leaf spot and the like under a high-temperature and high-humidity environment; after the cutting slips root, the root growth, branch development and the like are limited by the growth space and are stressed by competition among the cutting slips, and the high growth amount of the cutting seedlings in the current year is only about 20-30 cm generally. In addition, because the cutting bed type centralized cutting is adopted, the root systems are young and tender in a growing period after the cutting slips take roots and are not easy to dig and transplant after being staggered, and the root systems are staggered and easy to damage during seedling raising, so that the cutting slips stay in a bed for a long time, generally, the seedlings which survive through cutting are transplanted out of the bed after falling leaves in autumn or before sprouting in the next year, and container seedling cultivation or field planting cultivation can be further carried out.

And a degradable non-woven fabric cutting seedling raising bag with the specification of 6 multiplied by 5cm is also adopted, and after cutting is finished, shading and spraying maintenance is carried out, wherein the maintenance at the stage is generally carried out by regularly controlling optical spraying. And (4) growing root systems of most of the cutting seedlings from the side surfaces and the bottoms of the seedling bags at the bottom of 8 months, wherein the average growth of young shoots is 8-10 cm.
Transplanting cutting seedlings in the beginning of 9 months, selecting non-woven fabric seedling bags with the specification of 20 multiplied by 20cm, preparing a matrix from plain soil and peat soil according to the volume ratio of 1:1, maintaining the seedlings in the hardening period as in example 1, supplying water according to the moisture condition of the matrix after the hardening period is finished, applying 3-5 g of monopotassium phosphate compound fertilizer every 2 weeks, and stopping applying the fertilizer in the middle of 10 months. The growth quality evaluation is carried out at the bottom of 11 months, the average seedling height can reach 53.5cm, the average ground diameter can reach 0.6cm, and the growth is good.
Different proportions and components of the cutting matrix are adopted in the embodiment 2 and the embodiment 1, 1 part of plain soil is added in the embodiment 1, the water retention of the cutting matrix is improved, the spraying amount is reduced in the management of the cutting seedlings after cutting, but the influence of the proportions of the two matrixes on the rooting time and the rooting rate is not obvious; in the two embodiments, the cuttage seedling raising test of the sequoia intermedia is started in the first ten days and the middle ten days of 6 months respectively, the earliest rooting time of cuttage in the first ten days is slightly earlier than that in the middle ten days, but the rooting completion time of most cuttings in the two test cases is concentrated in the first 8 months, for better container seedling cultivation in the current year, the cuttage time is preferably selected before the middle ten days of 6 months and cannot exceed the bottom of 6 months at the latest, and the cuttage time is too late, so that the cuttings take root late and the rooting quality is not regular. The seedling of the taxus chinensis is in a rapid growth period of 9-10 months, the measures of fertilizer and water are proper, the high growth amount can reach more than 20-30 cm on average, and the seedling basically stops high growth after the seedling enters 11 months.
