Rice
|
Breeding new varieties of high yield with superior
grain quality is the main objective of rice research.
To improve cultivation practices suitable to grow rice
on the diverse geographical conditions is another objective
of rice research. On-farm experimental sites are often
served as the field demonstration plots for newly selected
promising lines as well as newly registered high-quality
rice for farmers, such as Tai-Keng No. 14, 15, 16, and
17. The planting area of high-quality rice in Miaoli County
increased to 6,200 hectares in the first crop and 5,600
hectares in the second crop that shares about 60% of paddy
field in Miaoli County.
Production of organic rice has recently been emphasized.
In addition to applying a large amount of compost, 4 tons/ha
of silicate slag is recommended to apply on the organic
field to inhibit the epidemic of bacterial blight disease
based on the result of research findings of this section.
Development of the disease resistant rice varieties with
good grain quality for organic production will remain
to be the main research subject in the future. |

Upland
Crops |
| Rotate rice with other upland crops is presently
very much encouraged. The paddy rice-dry land crop rotation
system developed after the repeated experiments is now
widely adopted by farmers. Currently, green manure, such
as vegetable soybeans, hyacinth bean and sesbania, are
recommended after the harvest of first crop of rice. Sweet
corn is rotated with strawberry for better pest management.
In addition to the technical aspects, the Station is also
helping the farmers to sell their products through various
markets. In the future, researches will be focused on
the variety improvement of upland crops such as tuber-use
sweet potato, leaf-use sweet potato, peanut, sweet corn,
edible cassava, pigeon pea and some newly emerged green
manure plants. Research to improve the cultivation practices
for these crops will also be carried out. |

Special
Crops |
| Chrysanthenum, Angelica, wild grape, perilla, leaf-edible
Chinese wolfberry, wild bitter gourd, wild yam and mesona
are special crops of economic importance in Miaoli County.
Cultivation methods such as pest management, methods of
pruning trimming, and harvesting, and fertilizer management
are the major concerns of the study for these crops. Recently
much emphasis is laid on the post- harvest technologies
such as processing, grading and packing of the farm products.
A 2-day symposium on packing of agricultural products
was organized by this Station in June 2000, to evaluate
the research findings of packing technologies. The Station
hasset initial project on food processing research with
special regard to fruit wine making to solve the problem
of over produced fruits in Miaoli County. In the meantime,
trials are carried ow on collected medicinal plants or
health crops with regard to their agronomic traits, their
adaptability to different climatic conditions as well
as their economic values of the new crop. Collection of
germplasm of economic importance will be continued in
the future. |

Vegetables
|
Vegetable researches are focused on organic cultivation
of different vegetables, such as strawberry, bitter gourd
and wild vegetables, under the field and greenhouse conditions.
A supply system for disease-free strawberry seedlings
will be established. Harvest time of strawberry can be
managed through the cold treatment of small seedlings,
to regulate the flowering time. This technique will enable
to prolong the harvesting period;thus the good price of
strawberry is insured. High-ridged bed is recommended
to farmers to grow strawberry so that to facilitate the
rotational cropping of strawberry with other dryland crops.
A simple net house has been recommended to farmers to
grow bitter gourd with a very good result. Predators such
as lacewings, predatory stinkbugs and mantis are released
in the net house to control insect pests and reduce the
application of pesticides. Honeybees are also moved in
the net house for pollination to increase gourd quality
and save labor cost on hand pollination.
Some wild edible plants are being tested for their potential
table use. They include hornwort, water cress, madeira
vine, nodding burn weed, gynura, vegetable ferns, purslane,
coral flower, white jute, Okra, bird nest fern (Asplenium
nidus), white mugwort, winged bean, mountain taro. |

Fruit
Trees |
Research are mainly concentrated on the improvement
of cultivation technique for local fruit trees such as
sorosis, persimmon, litchi and jujube. In general, sorosis
is harvested once a year between March and April, but
it can have another harvest in December when the growing
method is improved. Presently, organic farming of fruit
tree is much emphasized in order to establish Farm Tourism.
Bitter persimmon has an open and high canopy that makes
the work of picking fruit very difficult and tedious.
In order to improve this disadvantageous situation, an
experiment is going on to use Fu-yu variety as an intermediate
stock for grafting to dwarf the bitter persimmon tree.
This lately developed technique will be eventually widely
adopted by the farmers to save cost on harvesting.
Litchi is a high priced tropical fruit. Miaoli area
is near the northernmost limit for litchi cultivation.
In order to increase fruit set of the late maturing litchi
variety, No-Maz-Chee, various physiological aspects of
researches are being carried out at this Station, with
regard to its cultivation technique, effect of growth
regulators on the flowering performance and fruit quality,
fertilization management, and assimilate partitioning
in the plant.
Chinese Jujube is a special fruit in Kung-Kuan Township.
As a part of promoting tourism in Miaoli County, efforts
are made to dwarf tree plants so that the visitors can
easily pick the fruit. Organic farming coupled with biological
control to produce pesticide-free high-quality fruit is
also the main subject of research. |

Ornamental
Flowers |
With the recent economic growth, the business of
ornamental flowers in Taiwan is steadily increasing. Selection
of ornamental plants of economic importance for Miaoli
County is the primary objective of this project. Seedling
production and supply of selected ornamental plants is
crucial in the development of floral industry. Bulbs are
used to propagate the local orchid variety Pleione formosana.
Planting big and uniform bulbs is a key to produce the
high-quality flowers. Studies are therefore directed to
the method of producing large bulbs for distribution.
Based on our research findings, the bulbs of Pleione formosana
orchid are now propagated on the seed beds in layers with
the selected cultivation substrates.
Gladiolus and lily bulbs are propagated with a promising
result after treatment of temperature and chemical that
also enhances their resistance to disease. Technology
has been developed to dwarf the mulberry plants. which
can be adjusted to become "Bonsai" type ornamental
mulberry for commercialization. |
