| 摘要： Study the techniques for winter squash cultivation For the production of high-quality winter squashs in green house, this study will investigate the factors such us the cultivars, node of fruiting, and fertilization to improve winter squash quality and production, The high quality fruit and yield can be obtained. Improvement of Postharvest Technology and Storage Quality of Garlic Bulb Ta-Pen-Hey” is a major garlic cultivar in Taiwan. After harvesting, garlic is usually stored at room temperature with air circulation. However, the storage life can only last for 6 months. During autumn and winter, low temperature can induce sprouting and rooting results in wrinkled and rotten cloves. The man research goal for autumn and winter storage is therefore to prevent sprouting and rooting and to lengthen the storage life till the following February and March. Currently, garlic bulb after harvest exposed to hot air for a curing process until 20-30％ of weight loss is achieved before storage. The hot air treated cloves often show brown or yellow spot (known as ripen cloves) which may be related to temperature and the length of treatment. Thus, the purpose of this study is to set up the curing condition using hot air treatment and sky eye control system, to coordinate with vacuum low temperature storage technique and temperature fluctuation to reduce cloves deterioration and prolong its storage life, and to achieve a year round supply of garlic cloves. Breeding low glycemic index melon The quality of melon depends on sugar content and usually have Brix 13-16 degree which is sweeter than watermelon, In general melon is not suitable food for diabetic patient who regret to enjoy the pretty taste of melon. The influences of genetic and environmental factors on consisting of sucrose, fructose, glucose will be investigated for developing low GI (glycemic index) fruit of melon which may keep sweet taste as normal melon quality, because the sweet taste of fructose is higher than sucrose and its GI is 19 much lower than sucrose, so a high fructose content cultivar and cultivation technology may produce low GI melon fruit for diabetic patient food. Based on previous report that the component of sucrose, fructose and glucose are controlled by heredity and environment factors may modify these. The research program will look the genetic of sucrose, fructose and glucose, as well as cultivation season, shading, pruning and maturity of fruit and postharvest storage influences the components of sucrose, fructose and glucose. Study on the Supplymental Light Technique of Tomato Production under Protected Culture(3/3) In the past centuries, tomato had become one of the worldwide popular fruits due to its high nutritional value, low in calories, tolerance to storage and transportation, diverse cooking methods, etc. In tomato production, high quality plants is one of the most important factors in obtaining good yields. The good yield and quality tomatoes are usually produced from greenhouse or protected culture. Light is one of the main factors limiting the yield of tomato plants grown under greenhouse. Limited amount of available natural sunlight and diminished light intensity in winter reduces the growth and yield of tomatoes in the greenhouse. Supplementation of artificial lights in greenhouse is a better approach to alleviate this drawback. The objective of this project is to evaluate the suitable light environment and culture system to product tomato and to investigate the effects of light quality, interlighting regimes to extend photoperiod and to increase light intensity on the growth and yield of greenhouse-grown tomatoes. Improvement of vegetables production under protected structure- Establishment of low nitrate-content cultivating techniques of vegetables(2/3) The nitrate content in vegetables has become a significant issue in recent years. In order to reduce not only the farming production cost, but also environmental stress, this project aims to establish appropriate fertilization strategies and storage of different light environments for vegetables by conventional farming systems or organic cultivation. Long-term dynamics investigation and analysis the nitrate contents in 1,500 vegetable samples purchased from the metropolitan areas market. It is hoped that the results of this study will promote vegetable production as well as ensure human health and safety, environmental friendliness, and sustainable operation. In this study, Pak-choi, spinach, and lettuce of the Cruciferace family were examined. A study on the postharvest technique of okra This study is designed to develop an optimal postharvest technique to extend the storage limit of okra pods. By the technique developed, the storage life of okra pods during transportation, storage, sale, and processing can be improved. The long term storage technique also extends the distance of transportation which is able to provide fresh and high quality okra pods to fulfill the market requirement during non-season of foreign countries. The establishment of a plug-grown production system in strawberry nursery followed the three-step propagation system. Strawberry (Fragaria Xananasa Duch.) originated from North America and favors cool temperature, the fruit production of strawberry is restricted in mid-autumn to late spring in low land of Taiwan. Due to no professional nursery been established, majority of the framers propagate runner plants for their own need and as the result strawberry nursery is operated over the hot summer and often suffered from typhoon. In addition, the plant material was clonal propagated for years without renewing, growth vigor decades severely. Therefore, for solving the shortage of nursery plants. building up a production system based on the three-step propagation principles can be more important. The objective of this study is to integrate the plant factory and high-bed nursery system for strawberry runner plant production. We first renew the plant via tissue culture and propagate the first level plants in plant factory. The runner plants will be send to greenhouse high bed system for producing second levels plants before send to field high-bed system for third level production. In the previous project, we focused on the effect of cold storage of runner cuttings on nursery production. At the same time, the nursery schedule bypassed the typhoon season. The objective of this project will aim to amplify the yield potential. We will focus on the effect of container size on daughter plant quality and nursery production. The experiment will be conducted in the second and third level production. The resulted runner production and the nursery production after cold storage will be investigated. In our integrated system, we aim to stabilize the production of healthy strawberry runner plants, and the plug-grown strawberry plants will be operated 2 months before the field practice schedule. At the same time, in the purpose of avoiding detrimental environment, the farmers’ working schedule can be reorganized. |
