Embodiment 1
[0035] Embodiment 1 adopts the following steps to carry out eucalyptus water control and fertilizer control:
[0036] (1) Nursery site selection: The nursery site is selected in Guangzhou City, Guangdong Province, where the tropical sunshine is sufficient, the terrain is flat, the drainage and irrigation are convenient, and the leeward is sunny;
[0037] (2) Selection of potted plant bottom: Place 3 lightweight bricks (length, width and height are 60cm×20cm×20cm) side by side to form a square with a side length of 60cm, and apply 1.5cm thick cement mortar on top of the lightweight bricks. After the cement mortar is completely dry, the bottom of the potted plant is prepared for use;
[0038] (3) Selection of potting container: choose a black root control device with a width of 80 cm, cut it into a length of 180 cm and roll it into a cylindrical shape, and fix it with a cable tie through the hole of the root control device. The diameter of the cylindrical container is 52 cm;

Embodiment 2
[0046] Embodiment 2 adopts the following steps to carry out eucalyptus water control and fertilizer control:
[0047] (1) Nursery site selection: The nursery site is selected in the south subtropical area of Shaoguan City, Guangdong Province with sufficient sunshine, flat terrain, convenient drainage and irrigation, and leeward to the sun;
[0048] (2) Selection of the bottom of potted plants: place 3 lightweight bricks (60 cm x 20 cm x 12 cm in length, width, and height) side by side to form a square with a side length of 60 cm, and apply 2 cm thick cement on top of the lightweight bricks Mortar, when the cement mortar is completely dry, the bottom of the potted plant is prepared and set aside;
[0049] (3) Selection of potting container: choose a black root control device with a width of 80 cm, cut it into a cylindrical shape with a length of 180 cm, and fix it with a cable tie through the hole of the root control device. The diameter of the cylindrical container is 55 cm....

Abstract
The invention provides a water control and fertilizer control method for eucalyptus seedlings. By selecting proper root control devices used as potting contains and manufacturing special potting bottoms, root systems are prevented from penetrating into soil via the bottoms and soil steam is prevented from infiltrating into soil in the root control device containers to influence manual control conditions; effective water resistance, water control and nutrient control are realized through the technical means of white and black films and on-pipe type pressure compensation drippers; the volumetric water content of soil moisture can be rapidly measured by using a TDR 300 soil moisture analyzer, and the volumetric water content can better reflect the actual soil moisture content. The water control and fertilizer control method for eucalyptus seedlings can provide a complicated growth environment for the cultivation of eucalyptus seedlings; by combining the effective control of moisture and nutrients, the method realizes effective adjustment of the physiology of nursery stocks; the water and fertilizer coupling physiological effect of the nursery stocks can be further known, and primal parents of eucalyptus capable of adapting to complicated environment can be bred.
Description
technical field [0001] The invention relates to a water and fertilizer control method for seedlings, in particular to a water and fertilizer control method for large eucalyptus seedlings, and belongs to the technical field of seedling planting. Background technique [0002] Eucalyptus (Eucalyptus) belongs to Myrtaceae (Myrtaceae), native to Australia, Indonesia and their nearby islands, and is one of the famous fast-growing and high-yield tree species in the world. According to the Hill﹠Johnson classification system, in a broad sense, it refers to the tree species of the three genera of Cupberry, Corymbus, and Eucalyptus, and in a narrow sense, it only refers to the tree species of the genus Eucalyptus. According to the latest classification, there are 945 species, subspecies and varieties of eucalyptus. At present, 127 countries around the world have introduced and promoted planting. my country has introduced more than 300 varieties and hybrids since 1890, of which more t...
