How to grow Phalaenopsis orchids so they bloom again in summer
The normal flowering period of Phalaenopsis orchids is generally from February to May. Based on the author's experience, with proper care they can be made to bloom all year round. I have a new variety of "Big Red Flower Phalaenopsis" at home. After the Spring Festival I cut off the flower spikes and repotted it, and before "May Day" it began to send out new flower spikes again. On July 1 the first flower opened, and now they are blooming one after another. This is the second blooming in 2000. The cultivation method is summarized as follows: 1. Use an ordinary clay pot with an enlarged drainage hole at the bottom; it is best to make the drainage hole area reach one third of the pot bottom area. For clay pots, a medium

Feeding Livestock with Fresh Wheat Bran Requires Vigilance Against Stomatitis
Many breeders are accustomed to feeding fresh wheat bran directly to livestock, and untreated fresh wheat bran often punctures the oral mucosa of livestock and causes stomatitis. After livestock develop stomatitis, they want to eat but refuse food; they take feed into their mouths but dare not chew, or after chewing a few bites they spit the feed back out; white turbid mucus continuously flows from the mouth; and wheat awns can be seen stuck all over the tooth roots and the base of the tongue in the oral cavity. Once this disease occurs, first clean the wheat awns from the livestock's oral cavity thoroughly, then rinse the oral cavity with clean water to prevent infection. Then

What pesticide gives the best control effect against older larvae of the rice leaf roller?
Chlorpyrifos and abamectin-monosultap are effective agents for controlling the rice leaf roller, but they must be applied during the 1st-2nd instar young larval stage (at this stage the rice leaf roller has not yet rolled leaves and caused damage, or has just begun rolling the leaf tips and causing damage), when the rice in the field has just begun to roll leaves. For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

Tricks to Get Runty Pigs Growing Again: These Methods Are Very Practical
1. Deworming and stomach cleansing: Give trichlorfon orally at 0.017 g per kg of body weight once a day for 3 consecutive days. Two days after deworming, take 1 kg of quicklime, dissolve it in 5 kg of water, take the clear supernatant liquid and mix it into the feed to feed the pigs, once a day for 5 consecutive days, to clear worm eggs and various toxins from the gastrointestinal tract. 2. Strengthening the stomach and promoting digestion: Use 1 rhubarb soda tablet per kg of body weight (containing 0.3 g), with no more than 10 tablets per pig, grind into powder and mix into the feed, feed once a day for

Study on Immunization Methods against Swine Trichinellosis and Biochemical Characteristics of Trichinella Antigens
1. Biochemical characteristics of Trichinella antigens: For the first time, advanced techniques including sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), isoelectric focusing (IEF), two-dimensional electrophoresis and enzyme-linked immunoelectrotransfer blot (EITB) were applied to analyze 4 types of Trichinella antigens. The analysis showed that the soluble antigen of muscle larvae contains at least glycoproteins, lipoproteins, glycolipoproteins, simple proteins, polysaccharides and esterase isozymes. Two-dimensional electrophoresis revealed 122 polypeptide spots, most of which were acidic polypeptides with molecular weights below 67 KD.

How to manage garlic under plastic mulch after it turns green again? Remember these key points
1. Topdressing and watering. From late February to early March, temperatures rise and garlic under plastic mulch begins to turn green again. Because plastic mulch has a heat-preserving and moisture-retaining effect on the soil, generally, when garlic under plastic mulch has been watered thoroughly before winter for overwintering, it should not be watered early in spring, to prevent the soil temperature from dropping. If there is a spring drought and the soil lacks water, water once in early to mid-March. Remove the mulch in April, weed, loosen the soil, apply topdressing, and water. Apply 15-20 kg of urea or 30-40 kg of ammonium bicarbonate and 10-15 kg of potassium sulfate per mu. After fertilizing, irrigate once thoroughly. Appropriately control watering in the later stage. Keep the field

Fish heads contain substances that can fight against human aging
Professor Wang Cunxin, a fish research expert at the Institute of Oceanology, Chinese Academy of Sciences, says that fish brains contain a kind of fish oil needed by the human body, and fish oil is rich in highly unsaturated fatty acids, whose main component is what we call "brain gold." This is an essential nutrient for humans, mainly present in the phospholipids of the brain, and it can maintain, enhance and improve brain function. If intake is insufficient, the brain development process of infants will be hindered. Therefore, there is a saying that eating more fish heads can make people smarter. Professor Wang says that other parts of the fish head have no special nutritional

In early winter, farmers must guard against swine choking disease
Pigs of different ages, sexes and breeds can all be infected. Although the disease can occur in all four seasons, it is more common in the early winter when the climate is changeable, and it often occurs as a mixed infection or secondary infection with swine fever virus and Mycoplasma hyopneumoniae. The most acute cases can die within a few hours, before there is time for treatment. In acute cases, the main symptoms are septicemia and acute pleuropneumonia. Body temperature rises to 41°C, the pig is listless, appetite is completely lost, coughing and wheezing occur, breathing is difficult with a sitting-dog posture, the nostrils discharge a serous secretion, and the conjunctiva has a purulent secretion. First constipation, then diarrhea. In the later stage

Greenhouse Design: High Biosecurity in Greenhouses? Even More Need to Guard Against Highly Contagious Pests and Diseases
Greenhouses may appear to avoid many pests and diseases, but in reality they place even greater demands on everyday execution of environmental hygiene and safety. Only by being a bit finicky can you grow sweet, beautiful fruit. Let's take a look below. Biosecurity is not just a basic requirement for farms, poultry and livestock operations.
