Problems solved by technology

The use of traditional nitrogen, phosphorus and potassium compound fertilizers cannot meet the nutrient requirements for the growth of masson pine asexual seedlings. The growth of the plants shows obvious symptoms of fertilizer deficiency, withered needles, slow growth, and poor activity.
[0004] At present, the masson pine seedlings mainly adopt general compound fertilizer, which not only has a low fertilizer efficiency utilization rate for seedling cultivation, but also has a large potential environmental pollution problem.

Embodiment 1

[0028] A seedling raising method for promoting the growth of masson pine asexual seedlings. A non-woven bag with a size of 9 cm×12 cm is selected as a seedling cup. Mix peat soil, pine forest skin, yellow heart soil, pumice, fermented pine bark, and coconut bran in a volume ratio of 1:2:2:2:2:1 to prepare a substrate, and add 1.5 kg of slow-release fertilizer, stir well, and then put it into the seedling cup. Among them, N:P:K:Mg=7:40:6:2 in the slow and controlled release fertilizer. Use a stick to vertically punch holes in the substrate in the seedling cup with a hole size of 1 cm, and then fill the holes with yellow heart soil. Disinfect the matrix put into the seedling cup with a potassium permanganate solution with a volume concentration of 0.5%, and then rinse it with clean water. When the water content in the substrate is 70-75%, move the masson pine tissue-cultured seedlings with visible adventitious root length of 0.3-0.4 cm into the seedling cup with the substrate....

[0031] A seedling raising method for promoting the growth of masson pine asexual seedlings. A non-woven bag with a size of 9 cm×12 cm is selected as a seedling cup. Mix peat soil, pine forest skin, yellow heart soil, pumice, fermented pine bark, and coconut bran in a volume ratio of 1:2:2:2:2:1 to prepare a substrate, and add 1.5 kg of slow-release fertilizer, stir well, and then put it into the seedling cup. Among them, N:P:K:Mg=7:40:6:2 in the slow and controlled release fertilizer. Use a stick to vertically punch holes in the substrate in the seedling cup with a hole size of 1 cm, and then fill the holes with yellow heart soil. Disinfect the matrix put into the seedling cup with a potassium permanganate solution with a volume concentration of 0.5%, and then rinse it with clean water. When the water content in the matrix is ​​70-75%, the masson pine tissue culture seedlings whose adventitious root length is 0.4-0.5cm visible to the naked eye are moved into the seedling cup...

Embodiment 3

[0034]A seedling raising method for promoting the growth of masson pine asexual seedlings. A non-woven bag with a size of 9 cm×12 cm is selected as a seedling cup. Mix peat soil, pine forest skin, yellow heart soil, pumice, fermented pine bark, and coconut bran in a volume ratio of 1:2:2:2:2:1 to prepare a substrate, and add 1.5 kg of slow-release fertilizer, stir well, and then put it into the seedling cup.

Disinfect the matrix put into the seedling cup with a potassium permanganate solution with a volume concentration of 0.5%, and then rinse it with clean water. When the water content in the substrate is 75-80%, move the cutting seedlings of Pinus massoniana with visible adventitious root length of 0.3-0.4 cm into the seedling cup with the substrate...

Abstract

The invention discloses a seedling culture method for promoting pinus massoniana asexual nursery stock growth. The seedling culture method includes the steps of seedling culture cup selecting, matrix preparing, cup filling, disinfecting, seedling transplanting and water and fertilizer managing; peat soil, pinewood epidermises, yellow soil, pumice stone, fermented pine bark and coco coir are mixed by a ratio to obtain a matrix, an appropriate amount of controlled release fertilizer is added and stirred fully, the yellow soil and the matrix are loaded into non-woven bag seedling culture cups in the mode of putting the yellow soil in center holes and putting light matrix outside, the matrix is disinfected before seedling transplanting, then pinus massoniana asexual seedlings are transplanted into the seedling culture cups, water and fertilizer managing are carried out at regular time after transplanting until nursery stock is output for sell. The method has the advantages of being easy to operate, sufficient in resource, low in cost, high in fertilizer efficiency, good in absorption and beneficial for growth of pinus massoniana asexual nursery stock, the cultured nursery stock is high in quality, strong and high in growth speed, and the method provides technical support for pinus massoniana development and has good economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a seedling raising method for promoting the growth of masson pine asexual seedlings. Background technique [0002] Masson pine ( Pinus massoniana Lamb.) is the main afforestation tree species in southern my country. Due to the dual-purpose characteristics of resin and wood, it has high comprehensive utilization value and broad promotion prospects. In recent years, with the intensification of contradictions between people's growing living needs and the shortage of timber resources and the gradual depletion of non-renewable resources such as petroleum, the sustainable development of ecology, economy and society has attracted more and more attention from the society. Based on the problems of ecological safety, resource security and social security in our country, it is necessary to vigorously develop the masson pine plantation as the main industrial timber tre...
