Oriental Seed Industry's Rice Breaks World Records Three Times
Just as we were worrying about national food security, news came from Fujian Oriental Seed Industry Co., Ltd.: using the brand-new specific germplasm resources Donghui 6, Donghui 1728, and Donghui 4886 strong dominant restorer lines, they bred the new super rice varieties II You 6, II You 28, and II You 4886 through combination, achieving a historic breakthrough in which rice yield per mu surpassed the 1,200 kg mark, and in 2004, 2005, and 2006, for three consecutive years, with yields of 1,219.9 kg, 1,229

What is the best time to breed sheep?
The two months of September and October are the golden season for breeding sheep. Because the gestation period of goats is 152 days and that of sheep is 150 days, breeding at this time means lambing in February or March of the following year, when the weather is gradually warming; by the time the lambs grow big enough to eat grass, both adult and young sheep can eat fresh green grass, and together with the warm climate, this helps increase the survival rate of the lambs. At the same time, the lambs born that year, once they reach about 30 kg, can be bred again, which speeds up sheep reproduction and raises the turnover rate, so this opportunity must not be missed to breed the sheep during these two months. Whether goats or sheep, generally the ewes at

What time and conditions are needed for artificially rearing queen bees?
When the new bees reared by the colony that year have completely replaced the old overwintering bees and the colony has entered its growth and expansion period with a relatively strong population, you can prepare for artificial queen rearing. In the north, it is best to rear queens in early summer when the daytime temperature is stable above 20°C and there is a nectar source, especially when there is an abundant pollen source and drones also begin to emerge one after another. In North China this is generally in May. This can ensure the quality of the queen bee, and also allows the early replacement of aging queens with new queens. Colonies with a queen from the current year will not undergo natural swarming. Use the new queens reared early to carry out artificial colony splitting

When is the best time to harvest jujubes?
The ripening period of jujube fruit can be divided into 3 stages: the white-ripe stage, the crisp-ripe stage and the fully ripe stage. When to harvest the fruit should be determined by the intended use of the jujubes. (1) White-ripe stage: at this stage the green color of the peel fades, turning greenish-white or milky white. The flesh is soft and loose, the juice is scant, and the sugar content is low. For processing candied jujubes, harvesting should be done at the white-ripe stage. (2) Crisp-ripe stage: from the time the stem cavity and shoulders turn red until the fruit is fully red, the texture becomes crisp, the juice increases, and the sugar content rises sharply. For fresh eating and for processing wine-soaked jujubes, harvesting should be done at this stage. (3) Fully ripe stage: the peel

Annam leaf turtle spotted in the wild for the first time in 65 years
Researchers with the Asian Turtle Program have announced that late last month, in a wild area of Quang Nam Province, Vietnam, they captured an Annam leaf turtle, a species listed by the International Union for Conservation of Nature as one of the world's 25 most endangered turtles. It is said that the blood of the Annam leaf turtle can be used as a traditional medicine for treating heart disease. This year Vietnam passed a new law stating that it is illegal for anyone to keep or sell an Annam leaf turtle. The Asian Turtle Program is running an education and awareness campaign in Quang Nam Province, Vietnam, to guide people toward understanding the importance of protecting the Annam leaf turtle

Simple preservation techniques for oyster mushrooms help you extend storage time
Under normal conditions, oyster mushrooms are difficult to store and have a short shelf life. Two days after harvesting, oyster mushrooms lose freshness sharply due to water loss, the caps turn yellow, and an off-odor appears. During peak fruiting seasons, large quantities of fresh mushrooms flood the market at once, causing mushroom prices to plummet; on the other hand, during off-seasons and in cities far from mushroom-growing areas, there is little mushroom supply and nothing to sell. For this reason, here is a brief introduction to research on oyster mushroom storage and preservation. Method: Harvest oyster mushrooms at 80% maturity, remove diseased, insect-damaged, and damaged mushrooms, place them in a clean, cool, ventilated area, and use an exhaust fan for 1-1.5 days of air-cooling pretreatment, then

Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.

How Many Times Should You Actually Disinfect a Rabbitry? A Detailed Explanation of the Correct Frequency
The disinfection theory in books says, "Twice a week in summer, once a week the rest of the year." I think this disinfection practice involves far too many rounds. The purpose of disinfection is to kill harmful bacteria; my approach is once every half month in summer, and once a month the rest of the time. If you disinfect frequently, the aim is to kill harmful bacteria, but the result is that you kill all the beneficial bacteria too. Also, after we finish disinfecting, we sling the sprayer on our backs, turn around and leave the rabbit shed, leaving the rabbits in their cages reluctantly "inhaling the chemicals," and side effects are very likely to occur. Based on what I have observed

How to Keep Garlic Fresh for a Long Time? Try These Traditional Preservation Techniques
After the summer solstice, garlic bulbs entering dormancy are extremely sensitive to their environment (temperature and humidity), and the slightest mishandling can easily lead to rot and spoilage. Several traditional garlic preservation techniques are introduced below: 1. Mixed storage with bran. First spread a layer of bran about 20 cm thick on the bottom of a storage box (or basket), then stack the dried garlic bulbs layer by layer by piling one layer of garlic bulbs (a height of 2 to 3 bulbs is appropriate) and scattering one layer of bran, and when the pile reaches 40 to 50 mm from the rim of the storage container, cover it with bran so that the garlic bulbs are completely covered. This method mainly uses

Field management of wheat-intercropped cotton must be followed up in time
1. Growth and development characteristics of wheat-intercropped cotton. For wheat-intercropped cotton, the cotton seedlings are weak after wheat harvest, grow and develop slowly, bud and flower late, are prone to excessive vegetative growth in the mid-season, and tend to mature late in the late season; moreover, this year the cotton seedling stage was affected by rainfall and low temperatures, and seedling diseases were relatively severe. Field management after wheat harvest must be based on the word "early" and vigorously grasp the word "quick" to promote rapid growth and development of the cotton seedlings so as to make up for insufficient growth during the seedling stage. 2. Quickly destroy the wheat stubble and loosen the soil
