Problems solved by technology

Since the thickness of the covering soil is only about 0.1cm when sowing, the water droplets are too large to splash the seeds or sprouts when watering. It is also difficult to control the amount of watering. Too much water will cause the sprouts to be susceptible to germs, and too dry will easily cause the sprouts to dry up and die.
Many forest farmers and technicians have failed to cultivate Southwest Betula sprouts. The reason is that the water management requirements in the sprout cultivation stage are relatively strict, and there are differences in the water management of sprouts under different environments and substrates. Quantitative management is mostly judged by personal experience, and the failure of seedling cultivation is often caused by the inability to fully grasp the moisture status of the substrate during specific operations
In addition, the traditional seedling cultivation method has a long seedling cycle, and the emergence rate and uniformity of the sprouts are quite different, which is labor-intensive and time-consuming, which will have a great impact on the next stage of container seedling cultivation management and seedling quality

Embodiment 1

[0051] (1) Matrix configuration and loading

[0052] The matrix is ​​selected as yellow heart soil, and the matrix is ​​screened, and the part with larger particle size is removed by sieving or manually. The optimal particle size for screening is between 1 and 3mm, and the maximum particle size cannot exceed 4mm.

[0053] Clean and disinfect the seedling trays before loading. When installing the substrate, put a layer of clean newspaper on the bottom of the tray to prevent the substrate from leaking from the hole at the bottom of the seedling tray. The substrate is 0.5±0.1cm lower than the edge of the seedling tray, the thickness is 5.0±0.1cm, and the surface of the substrate is paved.

[0054] (2) Treatment and sowing of the matrix after loading

[0055]Put the seedling tray loaded with substrate into the seedling pond, and then pour water into the pond to keep the water level in the pond 0.3±0.1cm higher than the substrate in the seedling tray, so that the substrate can nat...

Embodiment 2

[0063] The matrix is ​​selected as yellow heart soil and vermiculite, and the yellow heart soil and vermiculite are mixed evenly in a volume ratio of 1:1.

[0064] Other steps are with embodiment 1.

[0065] Seedling effect: This ratio substrate is used for the shallow water seedling cultivation of Betula chinensis. Germination occurs after 3 days of sowing, and the sprouts emerge after 8 to 10 days. The growth is fast and uniform, and the seedlings can be transplanted after 60 days. Transplant seedlings 15 days in advance. The emergence rate can reach 90%.

Embodiment 3

[0067] The matrix is ​​selected from yellow heart soil and organic matrix, wherein the organic matrix is ​​a mixture of pine bark, retting sawdust and carbonized sawdust, and the yellow heart soil and organic matrix are mixed evenly at a volume ratio of 4:1.

[0068] Other steps are with embodiment 1.

[0069] Seedling raising effect: This ratio substrate is used for the shallow water seedling cultivation of Betula chinensis. Germination occurs 3 days after sowing, and the seedlings can be transplanted after 70 days, but the growth is not neat enough; the shallow water seedling cultivation of this substrate can transplant seedlings 5 ​​days earlier than the single yellow core soil substrate, and compared with yellow core soil and The vermiculite substrate was 10 days late. The emergence rate can reach 80%.

Abstract

The invention discloses a method for cultivating seedlings of betula alnoides in shallow water. According to the method, seedling cultivation discs filled with matrixes are put in a seedling cultivation pond to achieve an aim of watering by virtue of a soil moisture migration principle, thereby overcoming the defects of the conventional cultivation method. The method can alleviate artificial management on the cultivation of the betula alnoides seedlings, reduces the management difficulty, saves the seedling cultivation cost, obviously shortens the cultivation cycle of the betula alnoides seedlings, reduces disease incidence, and improves an emergence rate.

Description

technical field [0001] The invention relates to the field of cultivating strong seedlings of forest trees, in particular to a seedling raising method of Betula chinensis. Background technique [0002] Southwestern birch ( Betula alnoides Buch) is a tall deciduous tree belonging to the family Betulaceae (Betulaceae). The height of the tree can reach 30m, and the diameter at breast height can reach more than 1m. Southwest birch has a straight and round trunk, strong adaptability, resistance to barrenness, and rapid growth; its wood is a medium-to-high-grade wood, yellowish-brown or reddish-brown, with fine grain structure, moderate weight and hardness, and is mainly used to make medium-to-high-end furniture and wooden floors, Aerospace plywood and decorative plywood veneers. Betula is widely distributed in tropical, subtropical, and some mid-subtropical regions of my country. Betula plantations have spread over 150,000 hectares in Guangdong, Guangxi, and Yunnan, becoming on...
