example 1

[0045] Example 1: on February 24, 2012, the semi-lignified to lignified high-quality spikes of Camellia oleifera excellent clone Cenruan No. 2 and No. 3 were adopted, and the two-step seedling cultivation method was adopted in Guangxi Academy of Forestry to cultivate grafted seedlings of Camellia oleifera bud seedling stock, The seedbed width of Camellia oleifera grafted seedlings is 1.2m wide, 15cm high, and the path width is 40cm. The surface of the seedbed is evenly covered with a layer of yellow core soil with a thickness of 3cm. The survival rate of seedlings planted in the field with a row spacing of 0.5m*0.5m reaches 96.3%. Transplant into the seedling bag that diameter is 8cm, high 12cm in mid-June, the preparation of substrate is: yellow heart soil 85%, superphosphate 15%; Spray 0.5% water fertilizer (is about to be made into mass concentration of chemical fertilizer) after transplanting every 10 days 5% water and fertilizer), every half a month with 1000 times of tric...

example 2

[0046]Example 2: Common Camellia oleifera seeds were used for rootstock cultivation in November 2011. In February 2012, Cenruan No. 2, an excellent clone of Camellia oleifera, was used to cultivate grafted seedlings of camellia oleifera buds in Cenxi Camellia oleifera Seed Garden in two steps. , The seedbed width of Camellia oleifera grafted seedlings is 1m wide, 10cm high, and the path width is 35cm. The surface of the seedbed is evenly covered with a layer of yellow core soil with a thickness of 5cm. Transplanted into seedling bags in late June, the matrix preparation is: 90% yellow heart soil, 10% superphosphate; spray 0.2% water and fertilizer every 15 days after transplantation, and use trichlorfon powder 2000 times and 72% every 15 days Spray chlorothalonil wettable powder 2000 times liquid for control, and add humic acid liquid with a volume concentration of 0.1% at the same time. The survival rate after transplantation was 90.2%. In February 2013, the seedlings came ou...

Abstract

The invention discloses a two-step seedling culture method of grafted container seedlings of a tea-oil tree. The method comprises the following steps of: 1) culturing bud-stock grafted seedlings of the tea-oil tree in a large field: (1) selecting and treating nursery land, (2) culturing stocks: selecting seeds, disinfecting, germinating, spraying water for moisturizing regularly, taking out, and washing for grafting when germs grow to be 3-4cm in height and 2mm in thickness and before leaf expansion, (3) grafting: taking semi-lignified to lignified excellent clone branches as scions for graft from the last ten-day of January to the last ten-day of February in the year ensuing, and (4) planting; and 2): transplanting survival nursery stocks in the large field to a container for culture: (1) preparing a matrix, (2) filling the matrix and placing the container, (3) transplanting the grafted seedlings: transplanting the nursery stocks into the container and watering in the middle ten-day and last ten-day of June, and (4) managing after transplanting: managing fertilizer and the water and controlling diseases and pests of the nursery stocks, pulling up weeds and removing sprouts timely.The method can better solve the problem of container and matrix waste due to a low grafting survival rate, is high in operability and can effectively save cost.

Description

technical field [0001] The invention relates to a method for growing seedlings of forest trees, in particular to a two-step seedling raising method for grafted container seedlings of camellia oleifera. Background technique [0002] Camellia oleifera, oil palm, olive, and coconut are known as the four major woody oil plants in the world. Camellia oleifera combines ecological benefits, economic benefits and social benefits. It plays a very important role in increasing income, improving people's health status, and accelerating the process of land afforestation. To develop the camellia oleifera industry, seedlings are the foundation, and improved varieties are the key. To solve the bottleneck problem that restricts the development of the camellia oleifera industry, it is necessary to give consideration to the production capacity and quality of the camellia oleifera seedlings. Cultivating Camellia oleifera bud seedlings and grafting container seedlings is the main method for lar...
