Solar Power Theme Set For 2009 Energy Fair

solar power theme_During the recent 2009 New Energy International Forum &Solar Energy Fair, some 331 of the world’s leading alternative energy businesses agreed to invest in Sichuan and contribute to the growth of China’s alternative energy resources.

According to local officials, there were more than 700 industry specialists from nine different countries participating in the forum. This included representatives from the US, Germany, France, the UK, Italy, Spain, Japan, South Korea and Israel. Noticeably, many domestic and international research institutions were genuinely optimistic about the prospects for Sichuan’s new energy industry.

In the province’s Shuangliu county, alone, some 40 projects backed by local companies in the solar energy and wind energy sectors, were cited at the conference, leading to raised expectations for the country’s investment program.

Liao Weizhong, a senior official with the Sichuan provincial government, said: “To date, the total investment in our new programs is 5.63 billion yuan.”

According to Liao, during the forum Shuangliu signed strategic partnerships with a number of the country’s leading new energy research associations, including the China Renewable Energy Society and the Chinese Chamber of New Energy Industry.

The Institute of Optics and Electronics of CAS and the Nuclear Power Institute of China also signed strategic cooperation agreements with the county. These agreements will lead to the establishment of a State-level industrial base, focusing on optoelectronic systems and nuclear energy.

Upon completion of these projects, Shuangliu will be positioned as a dedicated new energy center, with an annual related turnover of more than 20 billion yuan. China Daily.

Now Is Time For Planning Spring Bulb Gardening

spring bulb gardening_When many gardeners are winding down their efforts, Heath is looking ahead. He’s helping gardeners get ready for spring by encouraging them to plant the bulbs now that will burst into bloom once winter subsides.

Heath, co-owner of the mail-order retailer Brent and Becky’s Bulbs, will be bringing inspiration to area gardeners when he presents a container-planting workshop and lecture Sept. 17 at Cleveland Botanical Garden. Both will focus on companion planting, combining bulbs with other types of plants for a more attractive and effective display.

While plants from bulbs bloom at various times of the year, spring is when bulbs are in the spotlight. They produce the familiar flowers of early spring — flowers like hyacinths and daffodils, tulips and crocuses — as well as lesser-known types such bellevalia and eranthis.

Heath loves playing with them. He enjoys engaging in what his wife and business partner Becky jokingly calls ”orgy gardening,” collecting lots of plants and putting them into a bed together.

He might start by planting spring-flowering bulbs in the fall, plug in some perennials the next spring, perhaps sprinkle in some wildflowers in summer and the following fall pull those out and overseed with biennials such as larkspur, violas or bachelor buttons.

Spring bulbs, he’s found, go well with perennials including pansies, violas and hellebores. Summer bulbs pair well with tropical annuals. And bulbs are ideal for planting amid ground covers, he said.

Both ground covers and perennials hide the maturing leaves after the flowers have faded, and they take up water from the soil to help keep the bulbs dry while they’re dormant.

Heath’s years of experience and experimentation — he grew up on a bulb farm — have taught him lessons about bulb-growing that sometimes fly in the face of conventional wisdom.

For instance, he takes issue with the advice that you can plant sun-loving spring bulbs under trees, because the bulbs will bloom before the leaves come out. That’s true, but when those leaves do appear, they’ll rob the bulbs’ foliage of the sunlight it needs to produce and store nutrients for the next year’s growth, he said.

So if you’re planting bulbs such as daffodils that you want to come back year after year, pick a spot that stays sunny, he said. Otherwise they might peter out over time.

He also disputes the suggestion that you can tie up the bulbs’ leaves after the flowers fade. That limits their exposure to sunlight and air, which they need, he said. Once the foliage starts to yellow, you can remove it.

Heath also has an unorthodox planting method for the clay soil that’s found on his Maryland farm as well as in much of Northeast Ohio.

Instead of digging holes for the bulbs, he spreads a 6-inch layer of compost over the soil and lays the bulbs directly atop the compost. Then he covers the bulbs with an appropriate amount of mulch — three times the height of the bulb, or about 6 inches of mulch for a 2-inch bulb.

As the mulch breaks down and dissipates over the years, he just adds more. ”They grow so much better,” he said of the bulbs. To discourage pests from munching on your tulip bulbs, Heath recommends coating them with a good animal repellant and letting them dry before you plant. Adding some sharp, crushed gravel to the planting hole helps, too, and it also improves drainage.

Or follow his lead and adopt a couple of cats. His own two pets keep his bulb-munching vole population at bay, although he said he’s had to train the cats not to go after birds.

What Heath encourages gardeners to do is think about and work with their own circumstances — their yard’s soil, microclimates and other factors. But that’s all part of the fun. By Mary Beth Breckenridge, Beacon Journal

Short-Haired Bumblebee To Be Repopulated In UK

short-haired bumblebee_British conservationists have drawn up plans to repopulate the countryside with a species of bumblebee that was declared extinct here nearly a decade ago.

The short-haired bumblebee officially died out in the UK in 2000, but descendants of the doomed community live on in small pockets of New Zealand, where they were taken to pollinate red clover in the late 19th century.

If the project is a success, it will mark the first time bees have been reintroduced to any country after the indigenous population died out.

Bumblebees and honeybees have been in decline nationwide in recent years. Bumblebees have suffered a dramatic loss of natural habitat, including wild flower and hay meadows, while disease and parasites have wiped out colonies of honeybees.

Scientists at the Bumblebee Conservation Trust will visit MacKenzie Country in New Zealand’s South Island this autumn, and spend up to two months hunting and capturing queen bees as they emerge from hibernation. The area is one of the last strongholds of short-haired bumblebees in New Zealand.

Any queens that are netted will be reared in captivity on the island, by feeding them nectar and pollen collected from a variety of flowers. The queens will have mated before being caught, and can lay enough eggs to produce a colony of hundreds of sterile worker bees. Details of the project are unveiled at the British Science Association festival in Guildford today.

Scientists hope some of the bumblebee colonies raised in captivity will grow large enough to produce a second generation of queen bees. These will be flown back to Britain during the hibernation season and could be released into their new habitat in Dungeness in Kent as early as next spring.

“It’s going to be difficult, but this might be our last chance,” said Ben Davill, director of the Bumblebee Conservation Trust.

The short-haired bumblebee is one of two species to be declared extinct in Britain in the past 70 years, the other being Cullum’s bumblebee. The insects have been hit hard by changes in agriculture, which have seen crop farmers replace nitrogen-replacing clover leys with fertiliser and hay meadows with silage.

The majority of Britain’s remaining 24 bumblebee species are able to feed on a wide range of flowers, but the short-haired bumblebee is a more fussy eater and only visits a few types of flower that produce high quality pollen.

Nikki Gammans, who is running the reintroduction project, has been working with local farmers, landowners and the public in Kent to restore the habitat in Dungeness by ensuring it has enough flowers to sustain the bees when they are released. “We are doing our best for this and all bumblebee species and hopefully they can do the rest,” said Gammans.
