2. Improvement of cultivation technology

(1) Research on the utilization of non-woven fabrics:

 In 1990, non-woven fabrics were developed for storage and packaging of fruits and vegetables after harvesting. In beans and tomatoes, the storage life can be increased by 5-10 days. In addition, non-woven fabrics with a basis weight of 14-18 grams/square meter are used to cover cabbage sprouts, and non-woven fabrics with a basis weight of 18 grams/square meter are used to cover green garlic, which can improve the quality and reduce the crude fiber content, especially to reduce pest damage and ensure the safety of vegetable consumption. .

(2) Eggplant V-shaped pruning technology: 

Compared with traditional pruning methods, the eggplant V-shaped pruning technology established in 1992 can improve yield and quality, and is more convenient for field operations. It has been widely used by farmers.

(3) Reuse of old media in facilities: 

Cultivation operators must replace (new) cultivation media approximately every 2-3 years, which poses the largest cost burden. In 1997, research and development of technology for reusing old media after facility vegetable and fruit cultivation can reduce farmers’ costs. The cost of purchasing new media is about 200,000-400,000 yuan/hectare, which solves the problems of high cost of purchasing media and reducing the amount of discarded old media.

(4) Garlic bulbs promote the establishment of a commercial production model for cultivation: 

In 1997, Hemei varieties or large black varieties were used. The garlic seeds were selected as high-spherical garlic bulbs. The garlic cloves should be moderate, with a small number of cloves, neat, solid, and free of infected nematodes and toxin diseases. . Refrigeration of garlic seeds at 10°C for 2-3 weeks before planting can promote early germination of garlic and delay the planting period to early October.

(5) Research and development of environment-friendly production technology for native specialty crops: 

From 106 to 110 years, we provided guidance on organic vegetable cultivation technology for the Wujie and Wanfeng tribes in Renai Township, Nantou County, assisted the tribesmen in soil fertility analysis and water quality testing, introduced environmental monitoring instruments, and investigated The correlation between microclimate changes in the cultivation environment and the occurrence of pests and diseases, and establishing an early warning mechanism for pests and diseases. We also provided guidance on cultivation techniques for summer organic cabbage and tomatoes, including variety selection, comprehensive organic pest control, and the introduction of microbial preparations - Bacillus amyloliquefaciens application technology. We successfully established the cultivation and management technology of summer organic cabbage and tomatoes for native tribes.

(6) Improvement of regional vegetable post-harvest treatment technologies: 

Develop post-harvest treatment technologies for various vegetable crops from 103 to 110 years, including:

1. After harvesting, young ginger can be refrigerated at 5°C and packaged in a single piece of vacuum packaging to keep its appearance smooth and non-yellowing. When stored in a non-woven PE bag, it can last up to 16 days before it begins to decay; the germination effect of seed ginger is estimated at 1% The germination effect is best when soaked in citric acid, packaged in PE bags, and placed at 30°C.
    
2. The storage method of taro is stratification storage at 5℃, which has better effect. Using coconut fiber as the stratification medium can store taro for up to 6 weeks.
    
3. The products of asparagus that are air-cooled indoors at 5℃ for 4 hours and pre-cooled by bottom layer water absorption have better quality. In addition, the products are stored in OPP plastic bags and stored at 5℃. Compared with the unpackaged control group, the quality of the products is better. Post-harvest quality decreases less, and the commercial value of garden products after storage for 2 days is still good.
    
4. It is recommended to remove the calyces and pods of sweet peas and pre-cool them to 5℃ with a 95% RH pressure difference as the appropriate post-harvest treatment method for sweet peas.
    
5. During summer cultivation of cabbage, reducing the amount of nitrogen fertilizer applied to 20 grams/square meter, harvesting with outer leaves and storing at 3~5℃ can effectively reduce the incidence of black spot disease. In addition, correlation analysis was conducted between plants with different degrees of black spot disease and their plant nitrogen content, nutrient elements, H2O2 and MDA content. The results showed that hydrogen peroxide and malondialdehyde showed a high quadratic positive correlation (R2=0.952 and 0.852). There is a negative correlation with ammonium nitrogen (R2=0.884), but there is no significant correlation with the contents of total nitrogen, nitrate nitrogen, phosphorus, potassium, sodium, calcium and magnesium. It can be speculated that oxidative stress damage to cells is responsible for causing black spot disease. cause.
