A kind of Huashan pine seedling raising method

Abstract

The invention discloses a method for culturing pinus armandi seedlings. The method comprises the steps that 1, a field is selected to establish a nursery, wherein an uncultivated field which is fertile in soil, humid, loosened, slightly acid and sandy in texture is selected from a shaded slope or a half shaded slope which is close to a water source; 2, container seedling culture is conducted, wherein a seedling culture medium is formed by mixing nursery soil, rotten rice chaff, peat, dry pond mud, slow-released granular fertilizer, humic acid calcium, rooting powder and Basamid granules; 3, medium filling is conducted, wherein after seedlings emerge, straw is uncovered, and a disinfectant nutrition medium is supplementarily filled to a nutrition pot after the seedlings are managed and protected to grow for 18-20 days; 4, seedling management is conducted; 5, the seedlings are moved out of a nursery and transplanted. According to the method for culturing the pinus armandi seedlings, when the nursery is treated, pine needles and sundries such as grass roots and weeds which are turned out are smashed and applied with rotten farmyard manure, a simulated ecological technology of applying fertilizer can be formed, nutrient substances which are peculiar to the pine needles and beneficial for growth of the pinus armandi seedlings can be released to be used for the seedlings, and the survival rate and the rate of emergence of the seedlings are increased.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating pine seedlings. Background technique [0002] Huashan pine, also known as fruit pine, green pine, five-leaf pine, white pine, five-bearded pine, horse bag pine, and calabash pine, is an evergreen tree in the Pinaceae family. Its tree shape is tall and straight, its bark is gray-green, and its leaves have 5 needles. Bunch, beautiful crown shape, strange posture, rapid growth, is a favorite greening tree species. Huashan pine likes light, is more cold-resistant, not resistant to high temperature and dryness, and likes a cool and humid climate. It grows quickly in deep, well-drained acidic soil, and is also the main tree species for afforestation on barren hills. In addition, Huashan pine can also be used as construction wood and industrial raw materials. Its pine wood is light and soft, with fine texture, easy to process, and resistan...

Problems solved by technology

The container seedling cultivation techniques disclosed in these two reports are all conventional methods, and no special management and protection are carried out during the seedling cultivation process, such as weeding, fertilization, watering, shading and other operations during the seedling growth period, although these operations can ensure the normal growth of the seedlings. Even fast and robust growth, but Huashan pine has high requirements for soil acidity and alkalinity, and ordinary fertilization will undoubtedly change the soil pH, which will affect the growth of seedlings. Defects, good will ensure the normal growth of seedlings or accelerate the growth of seedlings, and unfavorable ones will lead to poor growth of seedlings. Whether fertilization has positive effects or side effects on seedlings has a lot to do with the pH and buffering capacity of the matrix. Therefore, these two reports are used to make public The technical seedling cultivation has great limitations, and the manual inspection work is heavy and complicated
