Puli Branch Station Research


Passion Fruit Cultivation Management Research:

  1. Impact of Organic Fertilizers on Passion Fruit Growth and Soil Fertility:

    Recommends using beneficial microorganisms for reasonable passion fruit fertilization. The recommended application includes full compost (10 tons/ha of cow manure, 10 tons/ha of bagasse compost) and half the amount of chemical fertilizer (4 tons/ha) to reduce chemical fertilizer usage.
     
  2. Application of Agricultural Circulating Substances in Passion Fruit Fertilization Management:

    Using mushroom residues or fermented chicken manure as fertilizers increased total yield by 13%-68% compared to using untreated chicken manure.
     
  3. Application of Biological Liquid Fertilizers in Passion Fruit Cultivation:

    Weekly application of microbial liquid fertilizers through irrigation (100-300 times dilution) or foliar spray (300 times dilution) effectively maintained fruit productivity and stabilized quality.
     
  4. Application of Liquidized Starch Bacillus in Organic and Friendly Passion Fruit Cultivation:
    The use of liquidized starch bacillus (Tcba05) effectively controlled anthracnose and brown spot diseases, demonstrating comparable efficacy to pesticide treatments.

 

Application of Beneficial Microorganisms Value-Added Technology in Enhancing Crop Stress Tolerance:

The application of TCT768 solid-state microbial preparation and TCT-P001 liquid preparation in high-grafted pear cultivation reduced graft damage by approximately 15% under continuous low temperatures (26 hours). The treated group showed a significantly higher average fruit weight (385.3 g) compared to the control group (329.8 g).

 

Utilization Technology for Derivative Waste of Asparagus:

Developed a microbial material decomposer applicable to asparagus cultivation to process residues generated during production. This accelerates the decomposition of plant residues, providing organic matter back to the field, thereby increasing asparagus production and farmers' income.

  1. In asparagus fields, the use of liquid formulations containing beneficial microorganisms such as mycorrhizal fungi accelerates the decomposition of old leaves discarded in trenches during asparagus harvesting. This recycled organic matter provides essential nutrients for asparagus growth, reducing fertilizer usage by 1/3.
     
  2. Solid formulations in different ratios (1:1, 1:5, 1:10, 1:20) of mixed poultry and livestock manure with bamboo shavings undergo fermentation to reduce issues related to asparagus production residues and assist in the treatment of animal manure.

 

Application of New Wood Vinegar Formulation in Asparagus Cultivation:

Using wood vinegar formulations in asparagus cultivation resulted in lower incidence rates of rust and sesame leaf blight compared to the control group. The total yield survey showed that the wood vinegar-treated group yielded 29,831 kg/ha, the general formulation-treated group yielded 30,025 kg/ha, and the control group yielded 26,893 kg/ha.

 

Functional Microorganisms Application and Circular Agriculture:

  1. The TCT-P003 mycorrhizal strain exhibited rapid growth in liquid fermentation and effectively decomposed high-protein organic materials, reducing odors during the treatment process. It is applicable to kitchen waste treatment.
     
  2. Mycorrhizal fungi fermented with a high nitrogen formula for composting inoculants, applied in the decomposition of wood and bamboo shavings, shortens the fermentation process and develops related compost products.

 

Export Handling Technology for oriental cymbidium with Medium:

Oriental cymbidium orchids, exported as gift flowers to South Korea, have been traditionally transported bare-root. To meet industry demand, technology for exporting potted oriental cymbidium with medium has been developed.

  1. In compliance with South Korea's quarantine regulations for medium imports, single media such as sphagnum moss, bark, and coconut fiber can be used. Bark has the fastest planting speed, followed by coconut fiber, and sphagnum moss is the slowest.
     
  2. After bare-root handling, oriental cymbidium are planted. Mortality rates vary, with Cymbidium ensifolium ‘Tiee-Guu-Suh-Shin’ having the highest (25%-37.5%), Cymbidium ensifolium ‘rainbow’ next (4.2%-12.5%), and Cymbidium sinense ‘Sanchon’ having no mortality. Cultivation in quarantine facilities for 1-3 months post-export reduces mortality rates to 0-5%.

 

Development of New Medium for Oncidium Cultivation:

Utilizing waste mushroom sawdust and feather compost as the medium for oncidium cultivation, a mixture of full feather compost and 1/4 sawdust and 3/4 feather compost proved optimal for the growth of oncidium seedlings. Weekly treatment with Trichoderma liquid fertilizer resulted in the highest cut flower yield and A-grade flower ratio (30.8%).

 

Breeding of Native longiflorum-type Lily:

From 23 seed codes of longiflorum-type lily collected in 9 counties and cities in Taiwan, three superior native longiflorum-type lily individuals—L399S-4, L408S-1, and L408S-5—were selected through stages of bulb growth and multiplication. Subsequent strain and regional trials will be conducted to cultivate new varieties of longiflorum-type lily.
