How to prevent jujube fruit drop? These practical tips you need to know
Recently, many areas have had excessive rain, and many jujube trees drop a large amount of leaves and fruit during the young fruit stage, causing serious yield reduction. The jujube trees of a certain Fan in Sanfen Village, Nanhuangqin Village, Duancun Township, Xian County, Cangzhou City, are still green with lush branches and leaves, and the developing jujube fruits bend the branches. Even the seedless jujube, which normally has serious pre-harvest fruit drop, has not turned red or dropped this year and is growing well. Fan's specific methods are: take measures suited to local conditions according to this year's climate characteristics. Since June this year, there has been a lot of rain and high field humidity, which is suitable for small jujube fruit set. One jujube bearing shoot can grow dozens, even

To achieve high yield and high efficiency in fisheries, these three measures need to be implemented well
To achieve high yield and high efficiency in fisheries, efforts should be actively made to optimize the ecological conditions for aquaculture and strengthen the construction of supporting pond facilities. Specifically, this can be done from the following three aspects. 1. Implement the renovation of old ponds. The old pond renovation project should follow the requirements of "ecology, circulation, health, and intensification" and carry out major engineering construction such as "desilting and deepening, pond shape transformation, pond embankment slope protection, pond ridge widening and tidying, and improvement of supporting water, electricity, and road facilities," with particular emphasis on removing the thick layer of sludge at the bottom of the pond so that the bottom sediment is reduced to about 20 cm. Through desilting

How to manage a fish pond after the start of winter? These tips you need to know
1. Pond renovation. Use the winter slack season to renovate the pond: turn small ponds into large ponds and shallow ponds into deep ponds. After renovation, the pond's water-holding capacity can be increased and the pond environment improved. Ponds in relatively good condition should also be drained, and excessively thick mud dug out so that the mud thickness is kept at around 20cm. Remove weeds around the pond and raise and reinforce the pond embankments. 2. Pond disinfection. A properly repaired pond should be disinfected with quicklime. Pond disinfection should be carried out on a sunny day. For dry disinfection, use 50-80kg of quicklime per 667 sq m

Postpartum hypocalcemia in female dogs should not be ignored, and dog owners need to take it seriously
Postpartum hypocalcemia in female dogs, also known as postpartum eclampsia, postpartum tetany or lactation eclampsia, is a serious metabolic disorder in female dogs after giving birth. This disease is mainly characterized by hypocalcemia and muscle tonic spasms caused by abnormal excitation of motor nerves, accompanied by symptoms such as increased respiratory rate. This disease is paroxysmal and mostly occurs in small dogs or medium-sized high-yielding female dogs 10 to 20 days after delivery. At present, domestic techniques for diagnosing and treating this disease are relatively mature, and the treatment results are also relatively satisfactory. The basic approach is symptomatic treatment and calcium supplementation. The author, while treating 5 cases

Garlic "throwing small braids" phenomenon needs early prevention
In recent years, garlic has every year exhibited the phenomenon of "throwing small braids" due to various reasons. Scientifically speaking, this is the secondary growth of garlic, a major physiological phenomenon that affects garlic yield and quality, and it is also a problem of widespread concern among farmers in garlic-growing areas. In some plots, it can even cause widespread total crop failure of garlic, and its causes are relatively complex. As an agricultural technician providing postal services for agriculture, rural areas and farmers, the author now introduces the main causes and control measures as follows: 1. Select varieties suitable for local cultivation.

How to select and store sweet potato seed tubers? These methods you need to master
1. Timely harvest: If sweet potatoes are harvested too early, the yield is lower; if harvested too late, they are prone to frost damage, which affects storage. Therefore, it is generally best to begin harvesting when the temperature is around 18°C, and finish harvesting when the temperature is above 10°C (that is, before the frost-kill period). 2. Carefully select tubers: When harvesting and selecting good sweet potato varieties, you must dig and cut carefully to avoid wounds. In order to produce more sprouts, strong sprouts and lower costs, tubers weighing 150-200 g should be selected as seed. The selected tubers must be disease-free, free from flood damage, and also have the typical characteristics of the variety. At harvest,

What are the precautions for disinfecting fish species? These points you need to know
① In production practice, the specific drug used for disinfection depends on the fish diseases prevalent in the local area and the availability of the drug; the disinfection containers should be wooden basins, wooden buckets, fish bags, clay jars, etc., and metal products should not be used. ② The disinfection time is best chosen at 8-9 pm or 3-4 pm on a sunny day; a long soaking time kills pathogens more thoroughly, but if the time is too long and the dissolved oxygen in the water is insufficient, it will cause fish to gasp at the surface or die. Therefore, during the actual operation, special attention must be paid to the behavior of the fish. When the fish in the disinfectant solution cannot endure it

Pigs need a reasonable water supply, and pig farmers must pay attention to it
I. The harm of insufficient drinking water for pigs. At present, in pig raising there is a widespread phenomenon of only paying attention to feeding while neglecting drinking water, not realizing that drinking water for pigs is equally important as feeding, or even more important than feeding. The main harms of insufficient drinking water are: 1. Insufficient drinking water can lead to an increased incidence of intestinal diseases in pigs. In household pig farming by farmers, most use the traditional feeding method of supplying water and feed all at once, and between meals, regardless of the weather conditions and regardless of the type of feed, no drinking water is given. Because pigs are thirsty due to insufficient drinking water, especially in hot summer, they often drink dirty water

How to prevent and treat selenium deficiency in raccoon dogs? Farmers need to master these methods
Selenium deficiency has obvious regional characteristics. Generally, a selenium-deficient geological environment causes selenium deficiency in humans and livestock, especially in years with abundant autumn rain, when selenium in the surface soil is lost with the rainwater, and herbivorous or omnivorous animals find it difficult to obtain enough selenium from plants, thus causing selenium deficiency. The narrow belt from Northeast to Southwest China is all selenium-deficient areas, with western Heilongjiang Province and Liangshan in Sichuan being the most deficient. In selenium-deficient animals, the selenium concentration in the organs and tissues of the body decreases. Under actual production conditions, liver necrosis may occur, or it may appear together with muscular dystrophy, mulberry heart, and white muscle disease. Clinically, various animals show different manifestations, but the common manifestations are decreased productivity, reduced number of offspring, infertility, movement disorders, and in mammals, retained placenta. When raising animals in selenium-deficient areas, attention should be paid to selenium supplementation.
