What control measures should be taken when pathological changes occur in garlic scapes during storage?
Abnormal changes of the scape tip 1. Browning of the scape tip (1) Symptoms The scape tip changes from yellow-green to yellow-brown or dark brown, dehydrates and shrinks into a thin flake-like form, is prone to decay, and is easily infected by mold, losing its toughness; dry-affected ones break easily, and wet-affected ones rot easily and are infected by mold. (2) Causes The tissues of the scape tip undergo physiological aging and death, and lose water and shrink. High temperature and high oxygen promote browning, and high humidity aggravates the degree of browning. (3) Control Harvest at the proper time, and strictly prevent high temperature, air-drying, or smothering during harvest and transport.

Feeding and Management Tips for Young Sheep During the Growing Period
Growing sheep refers to young sheep in the age range from weaning to first mating. For 3-4 months after weaning, growth and development are rapid, weight gain is intense, and the demand for feeding conditions is high. After 8 months of age, the intensity of sheep growth and development gradually declines. Key feeding and management points for the early growing period: During this period, especially for newly weaned lambs, growth and development are rapid, the rumen volume is limited and its function is not yet fully developed, and the ability to utilize roughage is relatively poor. Therefore, during this period the sheep's diet should be based mainly on concentrate and can be supplemented with high-quality hay and fresh green

How to manage cotton during the dog days? Please check this guidance
According to the citywide "715" survey summary, this year our city's cotton growth progress is fast and the cotton is growing well. This is shown by: fast growth progress, uneven growth, and a large area of cotton entering the dog days with bolls. The citywide average cotton plant height is 88.38 cm, an increase of 2.01 cm over last year; the total number of fruiting nodes is 49.80, an increase of 7.77 over last year; the number of abscised squares and bolls is 4.39, a decrease of 0.15 over last year; the abscission rate is 8.8%, a decrease of 1.99 percentage points over last year. The area entering the dog days with bolls accounts for 10 of the cotton field area

Key Management Techniques for Shiitake Mushroom Bags During the Color-Turning Period
As early November arrives, temperatures drop noticeably and the day-night temperature difference widens. As a result, the shiitake mushroom bags produced in mid-September this year had just finished colonizing when the temperature fell, prolonging the maturation period of the bags and making it difficult for the mycelium to turn color. This is especially true for short-aging shiitake varieties, which may show the abnormal phenomenon of fruiting before color turning. The following two points should be noted in management: 1. For long-aging shiitake bags whose mycelium has fully colonized but has not yet turned color, management can be divided into two approaches. First, after punching holes, be sure to keep the cultivation room temperature above 22°C, and ventilate appropriately for 1-2 hours at noon each day;

Cultivation of oyster mushrooms (Pleurotus pulmonarius) during the summer idle period can utilize shiitake mushroom sheds in high-altitude mountainous areas
Pleurotus pulmonarius is a medium-temperature variety, with a fruiting range of 15-28°C and an optimum of 18-22°C, and can fruit naturally in spring and autumn. Because Pleurotus pulmonarius has the characteristic of fruiting under variable temperature, under environmental conditions above the fruiting temperature range, proper low-temperature differential stimulation (temperature difference above 10°C) can promote fruiting body formation. In current production, during the summer high-temperature season when temperatures exceed 28°C, the method of placing physiologically mature spawn bags in a 2-4°C cold storage for cold stimulation for 10-12h, then moving them to the mushroom house for fruiting, is adopted for off-season

Management Methods and Care Points for Firethorn Bonsai During the Fruiting Period
Firethorn bonsai is a fruit-ornamental bonsai, so whether making small, medium, or large bonsai, after shaping, fertilizer and water management and pruning must be strengthened so that it grows vigorously year after year, with abundant flowers and leaves and heavy fruit. So, how should firethorn bonsai be managed during the fruiting period? In our northern Guangdong region, firethorn generally blooms and sets fruit from early April to mid-April. Generally, applying a phosphorus fertilizer once before flowering and ensuring sufficient light is enough. After fruit set, apply a mixed phosphorus-nitrogen fertilizer solution once a month to make the fruit large and beautifully colored. In April and May, special

Detailed Explanation of Key Management Techniques for Does During the Breeding Period
After the beginning of autumn comes the breeding, gestation and lactation period for does, and artificial rearing management must be tracked in place from beginning to end to ensure the economic benefits of artificial deer farming. 1. Organizing the doe herd before mating. Before mating, does that are infertile, have vicious habits, are too old, or have serious diseases and no breeding value should first be removed from the herd. And according to blood relationships, age groups and health conditions, etc., form a breeding core herd, a general breeding herd, and a first-mating doe herd. A breeding group should preferably consist of 15 to 30 does. The body condition of does

How to classify and manage cotton during the flowering and boll stage? Jinnan District Agriculture and Forestry Bureau reminds cotton farmers
The period from when 50% of cotton plants flower to when 50% of cotton plants mature and open their bolls is called the flowering and boll stage. Cotton in Tianjin generally enters the flowering and boll stage in early July and finishes at the end of August. This period is the key period that determines cotton yield, and cotton farmers are urged to pay attention to the growth trend of cotton in the field and adjust technical management measures at any time. According to Gao Qingming and others of the Cotton Research Institute of the Hebei Academy of Agriculture and Forestry Sciences, based on morphological indicators such as cotton plant growth during the flowering and boll stage, cotton fields are classified into 4 grades: excessive vegetative growth, robust, ordinary, and weak. The main indicators of the 4 grades are as follows: ①

How to manage cotton during the flowering and boll-setting stage? Jinnan District Agriculture and Forestry Bureau reminds cotton farmers to master the techniques
The flowering and boll-setting stage of cotton in Tianjin generally begins in early July and ends at the end of August, lasting 55 days. According to surveys, most of the cotton fields in our district have entered the flowering and boll-setting stage. Field management during the flowering and boll-setting stage is very important. This period is when cotton grows and develops most vigorously, and it is a period of intricate and complex contradictions among vegetative growth and reproductive growth, individuals and populations, and the cotton crop and the environment, so it is the period that determines yield. Cotton field management during this period should focus on doing the following key tasks well: 1. Increase potassium fertilizer application. Increasing

Management methods for roses during hot and rainy seasons
The reason potted roses die in summer is mostly because the potting soil was not mixed well, the pots were not repotted and the soil was not changed in spring, and the nutrients in the original potting soil were largely depleted. As a result, the roses cannot withstand the high temperatures and die. In the high-temperature summer season, roses are almost in a semi-dormant state. Some people see that roses do not bloom or bloom little and think it is due to insufficient fertility, so they apply more fertilizer and concentrated fertilizer. In addition, the high summer temperatures accelerate the fermentation of the fertilizer, and the rose roots are burned. After repotting and changing the soil, place it in a cool place for about a week before resuming normal
