What causes secondary branching and deformed scapes in garlic? Here's how to prevent it
Every year during the scape-elongation stage of garlic, a certain proportion of garlic plants develop secondary branching and deformed scapes, seriously affecting the yield and quality of garlic scapes. In recent years, we have carried out investigations and research, and have explored effective agricultural measures to control the occurrence of secondary branching and deformed scapes in garlic, which have played a very significant role in improving the economic benefits of garlic growers. 1 The harm caused by secondary branching and deformed scapes in garlic. Secondary branching in garlic is also called secondary growth or branching, and growers call it "horsetail garlic". There are generally two phenomena: first, branches differentiate from the outer leaf sheath,

Causes of Secondary Growth in Garlic and How to Prevent and Control It
Garlic is one of the indispensable vegetables in people's daily lives, and it is also a popular vegetable that can be supplied year-round on the market. However, in recent years, due to improper planting methods, management practices, and other factors, a large amount of secondary growth in garlic has appeared, commonly known as "horsetail garlic" or "bread garlic," which makes the garlic unsuitable both for seed saving and for eating, severely reducing its marketability and economic benefits. What exactly causes secondary growth in garlic, and how should it be prevented and controlled? The author

Diagnosis and Treatment Experience of Secondary Infection with Hemotropic Mycoplasma (Eperythrozoon) in Canine Distemper
Canine distemper mainly affects young dogs, and its pathogen is canine distemper virus. Affected dogs are characterized by a biphasic fever pattern, rhinitis, severe digestive tract disorders and respiratory tract inflammation. However, cases of mixed infection of canine distemper and canine hemotropic mycoplasma (Eperythrozoon) are relatively rare. 1 Onset and Symptoms The affected dog was 8 months old, clinically diagnosed with canine distemper, with a disease course of 1 week, and had already been treated with canine pentavalent serum, antibiotics, etc. When it came to our hospital for treatment, it was confirmed to have secondary lobar pneumonia, with a body temperature of 40.6 degrees C, showing a biphasic fever pattern (that is, at the beginning of the disease the body temperature rises to about 40 degrees C

Stem Cell Research Opens a Second Front for the Cloning Sheep Technology Route
The Leap from Sheep to Monkey Without the two papers published on November 20, Shoukhrat Mitalipov would have been the most watched stem cell research scientist during this period. On November 14, this scientist at the Oregon National Primate Research Center in the United States published a paper in Nature, announcing that he had successfully obtained cloned rhesus monkey embryos. This was the first time scientists had cloned viable

Cotton narrow row spacing should be widened: The second in a series of recommendations from rural advisory services in 2008
Before sowing, the author visited and investigated some cotton regions in Hebei, Shandong, Shanxi and Shaanxi. In most areas the cotton narrow row spacing is too narrow, seriously hindering the normal growth and development of cotton plants, and a planting reform of the population structure is essential. The pressing task is to widen the narrow row spacing. In order to carry out plastic film mulching of cotton, cotton farmers mostly adopt wide-and-narrow row sowing, sowing two rows at once. Most areas use 90 cm wide plastic film, with the narrow row spacing about 45 cm wide. This is not conducive to the normal extension of fruiting branches and flowering and boll setting, and also causes unbalanced growth on both sides of the cotton root system. Very

What are the methods for getting Schisandra chinensis to produce a high yield in its second year?
In the process of cultivating Schisandra chinensis, a single plant with two canes is generally used. With good management, it can fill the trellis in the same year, but most plants fill only half or a bit more than half the trellis. Nowadays, it is best to plant a single plant with a single vine. The specific method is to leave half a trellis in the first year; that year the cane can grow 2 m, the main vine's thickness can reach more than 0.4 m, and in the second year the yield per mu can reach more than 400 jin. In the spring of the second year, reserve canes are selected at the base of the main vine and from the underground stem, and in the third year the two vines bear fruit. Another method is the close-planting method, that is, 2200 plants per mu,

How to treat swine influenza secondary to Haemophilus parasuis infection in pigs
Swine influenza is an acute, highly contagious disease of pigs, characterized by sudden onset and rapid spread through the whole herd. The main symptoms are upper respiratory tract infection, and it generally occurs in winter and spring and when the climate changes abruptly. The disease also often occurs secondary to Haemophilus parasuis infection in pigs. Outbreak situation: Yang, of Baimaqiao Township, Xiangning County, Shanxi Province, raised more than 40 pigs, including 18 finishing pigs, 11 feeder pigs, and the rest piglets. Because the owner used a swill-feeding method, the farming was also not well developed,

The Second of the Six-Part Series on Autumn Production of Edible Mushrooms
First, select good spawn. The main varieties used this autumn are: 1) Oyster mushroom: "8359" and "Nongke 12" -- suited to fruiting in spring and autumn; spawn-running temperature 5-36°C, optimum 24-28°C; fruiting temperature 5-25°C, best 18-20°C; clustered or imbricate overlapping growth, small thick caps, large clusters, cap grey to dark grey, stipe slender and short, gills white and fine, cluster shape compact, flesh firm, good market quality; these two strains have strong resistance to contaminants and diseases, and in general production they do not become infected with diseases such as yellow mushroom disease

Secondary bagging of edible fungi can effectively prevent infection
In the production of shiitake mushrooms (Lentinula edodes), lion's mane mushrooms (Hericium erinaceus), wood ear mushrooms (Auricularia heimuer) and others, the secondary bagging technique is applied (that is, when the mushroom logs come out of the sterilization chamber, an extra layer of thin film bag is put on, so that the mushroom logs inside the bag do not come into direct contact with the ambient air), which effectively solves the problem of cross-infection during the log production process and keeps the strain survival rate above 97%. The technique is described below: 1. Preparation of the outer bag The outer bag should preferably be a low-density polyethylene film bag with a circumference 2 cm larger than the inner bag, a length 5 cm longer than the inner bag, and a thickness of 0.2 silk, with one end tied and sealed for later use.

Key Breeding Techniques for Early Growth of the Second-Crop Velvet in Deer
There are 2 methods for harvesting velvet antler: sawing the antler and cutting the antler. Among them, sawing the antler generally starts from 3-year-old deer, and can be harvested 2 times per year. The 1st time is 45-50 days after Qingming, called "first-crop velvet", and the 2nd harvest is 50-60 days later, called "second-crop velvet". To promote early growth of the second-crop velvet, the following measures can be taken: 1. Select superior deer breeds - generally, the regeneration velvet yield of Tianshan red deer and Tarim red deer is significantly higher than that of Northeast red deer, so to obtain more regeneration velvet, it is best to choose to raise these two pure red deer breeds. 2. Utilize hybrid advan
