Problems solved by technology

With the existing fertilization technology and chemical fertilizers, nutrients are easily absorbed by weeds, lost with rainwater or inactivated by long-term exposure, so that the nutrients finally absorbed by plants account for a small part of the total nutrients, and the cost of fertilization is relatively high. The synergy is not obvious, and it is easy to cause environmental pollution, soil compaction, soil deterioration, soil fertility decline, affect the respiration of tree roots, and aggravate the occurrence of diseases and insect pests

Embodiment 1

[0020] Embodiment 1: the preparation of Pinus massoniana anti-adversity health-care mycorrhizal agent

[0021] Inoculation test was used to test and screen Lactarius akahatsu, Lactarius hatsudake, Lactarius camphorates, Lactarius glyciosmus, Lactarius subzonarius, and Lactarius subdulcis picked in Pinus massoniana forest. , Lactarius porninsis, Lactarius gerardii, Lactarius deterrimus, Lactarius echinatus, Lactarius hygrophoroides, Lactarius vellereus, Lactarius volemus, etc. Effects of inoculation of 13 kinds of milk mushrooms on the survival rate of 2-year-old Pinus massoniana seedlings. After 3 months of inoculation, it was found that the survival rate of the masson pine seedlings inoculated with Lactarius akahatsu and Lactarius hatsudake was the highest, and the survival rates of the seedlings were 81.57% and 77.82%, which were 28.15% higher than the control and 26.26%, the survival rate of seedlings inoculated with other strains was lower. The experimental results show ...

Embodiment 2

[0025] Embodiment 2: fertilization method:

[0026]First of all, when the masson pine is arranged in a matrix or a square array, a pit is dug in the middle of the line between every two adjacent trees in the horizontal and vertical directions, and every two adjacent trees in the horizontal and vertical directions share a pit. There are 4 pits, and the distance between each pit and the main tree trunk is 1.0 meters; the anti-adversity health mycorrhizal fungal agent (prepared by two kinds of bacteria, milk mushroom and milk mushroom) and organic fertilizer are put into each tree at intervals In the 4 pits around the tree, fertilize once a year, and the fertilization time is in the middle and late April.

[0027] Cover the soil and water; the length × width × depth of each pit = 25-35cm × 15-25cm × 25-40cm; the amount of bio-organic fertilizer in each pit is 2000 grams, and the amount of adding polyacrylamide water-retaining agent The amount of anti-stress health mycorrhizal ag...

Abstract

The invention discloses a fertilizing method for improving stress tolerance and productivity of a masson pine forest. The method includes the following steps: when the masson pines are arrayed in a matrix or a square matrix, a pit is dug in the middle of a connecting line between every two adjacent trees in the transverse and the longitudinal directions; every two adjacent trees in the transverseand the longitudinal directions share one pit; and four pits are dug on the periphery of each masson pine; stress tolerance health protection mycorrhiza fungicide and organic fertilizer are mutually spaced and placed in the four pits on the periphery of each tree, and earthing is performed then. The stress tolerance health protection mycorrhiza fungicide is compounded and formulated by mycorrhizafungicide and naphthylacetic acid or indole-3-acetic acid, and the mycorrhiza fungicide is fermented by lactarius akahatsu and lactariushatsudake through solid fermentation stock culture; and biological organic fertilizer provides necessary nutrient for the growth of masson pines, and the stress tolerance health protection mycorrhiza fungicide facilitates the rootage and growth of the masson pines, so that the stress tolerance of the masson pines as well as the soil condition and micro ecology environment are improved, the survival rate and growth rate of the masson pines are enhanced, the rich water loss is reduced, and the competition for weeds below the masson pines and shrub for fertilizer is alleviated.

Description

Technical field: [0001] The invention belongs to the field of fast-growing artificial forest cultivation, is suitable for hills, low mountains and flat areas, and can fertilize young forests, middle forests and mature forests, and specifically relates to a fertilization method for improving stress resistance and productivity of Pinus massoniana forests. Background technique: [0002] Masson pine forest is a major type of forest ecosystem degradation in southern China. The degradation is characterized by loss of species diversity, poor water storage function, low microclimate regulation efficiency, severe soil fertility decline, unstable community structure, and serious pest damage. Artificial fertilization to supplement soil fertility is one of the most direct and effective methods for soil fertility restoration. With the existing fertilization technology and chemical fertilizers, nutrients are easily absorbed by weeds, lost with rainwater or inactivated by long-term exposur...
