The application discloses an organic and inorganic fertilizer precision application agricultural planting machine and a working method, and relates to the technical field of agriculture. In the application, the lower end of the first conveying pipe extends into the material guiding cavity, the mixing assembly rotates between the two ditching and material guiding assemblies, the seed guiding part is arranged between the storage assembly and the corresponding material guiding cavity, the organic fertilizer output assembly is arranged in the organic fertilizer storage tank, the first driving rod is provided with a spiral auger extending into the first conveying pipe, and the hollow single-seed part in the power seed guiding ring is used for receiving the single corn seed falling from the storage assembly. The application can realize the regulation and control of the output amount of the organic fertilizer in the first conveying pipe, meet the output of different content organic fertilizer particles, realize the synchronous application of the seed and fertilizer mixture into the fixed point soil hole, realize the synchronous hole application of the chemical fertilizer while the seeding and the organic fertilizer application are realized, improve the seeding and fertilizing efficiency, and avoid the fertilizer waste problem caused by the continuous strip seeding.

This invention relates to the field of grain dryer technology, specifically to a grain dryer discharge mechanism with an anti-breakage structure. The mechanism includes a main body with a discharge chamber at its bottom, connected to a grain receiving hopper at the bottom; a frame unit located within the discharge chamber, comprising a first frame slidably connected to the inner wall of the discharge chamber, and a second frame slidably nested in the middle of the first frame; both the first and second frames have connecting grooves on their outer walls, with the two sets of grooves facing opposite directions; a partition plate fixed inside the discharge chamber above the frame unit, with several discharge ports extending through its top; and a drive unit located within the discharge chamber. This invention enables low-breakage discharge throughout the entire grain dryer process, single-drive multi-mode controllable discharge, and also helps to break up knots and prevent damage. The purely mechanical structure ensures stable operation and is suitable for drying various grains.

This application discloses a method for directly cultivating seedlings from the germination of *Cymbidium goeringii* seeds in Yunnan. The method includes the following steps: sowing *Cymbidium goeringii* seeds on a modified culture medium, followed by 6 months of constant temperature cultivation at 25℃ to obtain small pseudobulbs suitable for direct transplanting. This method is simple to operate; seeds begin to germinate and turn green 20 days after sowing, begin to grow leaves after 45 days, begin to root after 60 days, and show significant root growth after 90 days. The pseudobulbs also enlarge synchronously. After 6 months, the plants naturally shed their leaves in the tissue culture bottle, and the pseudobulbs can be transplanted to the field for acclimatization and cultivation. This method eliminates the need to change the culture medium, removes the manual transfer step in the tissue culture process, and solves the problems of yellowing, difficult rooting, and high contamination rates after transfer of tissue culture seedlings. Furthermore, the plants naturally shed their leaves in the tissue culture bottle, directly obtaining small pseudobulbs without hardening off, and improving the transplant survival rate, which is beneficial for the large-scale cultivation of *Cymbidium goeringii*.

This invention provides the application and method of Streptomyces S16-1 in promoting the growth and salt stress tolerance of Leymus chinensis, belonging to the field of microbial technology. Streptomyces S16-1 was isolated from saline soil, with the preservation number CCTCC M 20251940, and its 16S rDNA sequence is shown in SEQ ID NO:1. The Streptomyces S16-1 has functional activities such as salt and alkali tolerance, phosphorus solubilization, nitrogen fixation, and production of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase. The microbial fertilizer is obtained by expanding the culture of Streptomyces S16-1. Compared with chemical fertilizers, the microbial fertilizer used in this invention is more environmentally friendly. It can not only improve soil fertility and help plants improve their salt and alkali resistance, but also promote the balance and diversity of soil microbial communities, which helps maintain the health and stability of the soil ecosystem.
