Problems solved by technology

In this way, the spikes harvested in the remaining 6 months (January, February, June, July, November and December) are often discarded because they cannot meet the needs of the Chinese fir afforestation nursery stock market, resulting in the appearance of internal organs in the mother plant in the Chinese fir spike garden. Problems such as waste of stored nutrients and shortened ear-harvesting years have seriously affected the propagation and application of excellent clones in Chinese fir ear-harvesting nurseries

Embodiment Construction

[0021] In order to further disclose rather than limit the present invention, the present invention will be further described in detail below in conjunction with examples.

[0022] The mother tree of the Chinese fir ear picking nursery of Zhongfu Seed Industry Co., Ltd., Jianou City, Fujian Province was selected as the research object. The ear picking nursery is located on the south side of the Wuyi Mountains, which belongs to the low mountain and hilly area, and is located at 118° east longitude and 27° north latitude. It has a mid-subtropical marine monsoon climate, with a mild and humid climate, abundant rainfall, an average annual temperature of 18.7°C, and an altitude of 126 m. In 2012, when the shrub-type ear picking nursery was built, 7 500 kg·hm was applied to the nursery -2 Decomposed farmyard manure is used as the base fertilizer. The mother tree comes from the excellent clones of Chinese fir that are widely promoted in the market. At the end of December 2016, the roo...

Abstract

The invention belongs to the technical field of cunninghamia lanceolata vegetative propagation and particularly relates to a cunninghamia lanceolata stock plant yield regulation method. The method includes: in low-market-demand period of cunninghamia lanceolata cutting scions, namely in January, February, June, July, November and December, subjecting cunninghamia lanceolata stock plant roots to earthing-up and abscisic acid application to sharply reduce cunninghamia lanceolata stock plant yield to keep reserve nutrients in cunninghamia lanceolata stock plants; in March, April, May, August, September and October, removing covering soil, subjecting the roots to shading treatment, performing auxin spraying and trickle irrigation of nutrient solution, and cutting coppice shoots at cunninghamialanceolata roots to use for vegetative propagation. By the cunninghamia lanceolata stock plant yield regulation method, reasonable regulation of cunninghamia lanceolata stock plant yield is realized,and problems of waste of reserve nutrients in the stock plants, scion cutting term shortening and the like of a cunninghamia lanceolata scion nursery are solved.

Description

technical field [0001] The invention belongs to the technical field of Chinese fir asexual reproduction, and in particular relates to a method for controlling the yield of a Chinese fir ear-picking mother plant. Background technique [0002] Chinese fir[ Cunninghamia lanceolata (Lamb.) Hook] is a special useful timber afforestation tree species in my country. It has a wide distribution range, fast growth, high yield, and good material quality, and occupies an extremely important position in conifer plantation. In recent years, with the continuous increase of market demand, the afforestation area of ​​Chinese fir has become larger and larger. How to quickly reproduce and efficiently cultivate improved Chinese fir has always been a research hotspot for forestry workers. The spikes produced in the spike nursery have the characteristics of large quantity, strong growth, high rooting rate, and high genetic gain. Its establishment and development have become an important way to ...
