When do Choerospondias axillaris fruits generally ripen each year?
I discovered a problem: the sour jujubes I ate as a child were never ripe, so sour they'd make your teeth fall out. The sour jujubes I ate as a child were all green. Ripe sour jujubes are not that color. Let's see when Choerospondias axillaris ripens. Choerospondias axillaris fruits ripen in September-October, when the fruit skin turns from green to yellow.

Ditch Problems in Snail Farming and Their Solutions
When it comes to snails, I think everyone should be very familiar with them, especially since in recent years the market demand for snails has gradually increased. In recent years, China's late-night snack industry has developed very well, so the market demand for snails has also grown larger and larger. Ditch Problems in Snail Farming Snails

What are the common problems in cage farming of river snails?
I think everyone is very familiar with river snails. They are a fairly common dish in daily life, and are especially popular in the late-night snack industry. When eating late-night snacks or at food stalls in summer, I think everyone will definitely order river snails, so their market demand needs no explanation from me

How to solve the feed problem in gecko farming
1 Light trapping: This is one of the most effective methods. The insect season basically coincides with the gecko's main active feeding period, and with the breeding period when it needs the largest amount of food. In addition to hanging lights to attract insects in the rearing house, black-light lamps and ordinary oil lamps powered by batteries can also be used to collect insects.

How to deal with low reproductive rates in meat sheep? Practical solutions shared
Feeding fishmeal to meat sheep can improve the reproductive rate. Feed-grade fishmeal contains 90% dry matter, of which about 15% is ash, about 65% is crude protein (about 60% is digestible protein that can be directly used by animals), and about 7% is minerals such as crocodile [sic] and phosphorus. It is a good animal-based feed. In order to improve the breeding value of stud rams, further improve the efficiency of sheep artificial insemination, and explore ways to solve the source of protein feed, during the winter mating of 1972, at three mating points of the Heka Stud Sheep Farm, we trial-fed fishmeal to Xinjiang, Tsigai, Polwarth and crossbred rams bred on the farm, with good results. The feeding method is to sprinkle the fishmeal into the feed and mix it evenly. Fishmeal contains long-chain polyunsaturated fatty acids and is a good source of eicosapentaenoic acid and docosahexaenoic acid. Long-chain fatty acids have greater resistance to rumen bacteria. In addition to being rich in protein and more than 50% rumen-undegradable protein, which can increase milk yield and the protein percentage of cow's milk and sheep's milk, another important aspect of fishmeal is that it can inhibit the prostaglandin levels of cows and ewes. According to reports, 30 high-yielding ewes were fed diets with 0, 2.6, 5.2 and 7.8% fishmeal for a total of 42 days, and the results showed that inhibition of prostaglandins in ewes can improve embryo survival rate.</p><p></p><p>Supplementing more digestible undegradable protein in late pregnancy and early lactation can significantly increase peak milk yield and milk yield in the first 8 weeks of lactation. In most studies, milk composition increased somewhat, especially milk protein yield in early lactation. In addition, feeding more digestible undegradable protein may also increase appetite, and fishmeal is a good source of digestible undegradable protein.</p><p>Strengthen selection and mating</p><p>Selection of stud rams: select and breed rams from the offspring of ewes with high reproductive rates. They are required to have standard body shape and appearance, be robust, have well-developed testicles, and have obvious male characteristics, and through measures such as semen quality testing and progeny testing, discover and eliminate rams that do not meet the requirements.</p><p>Selection of ewes: select excellent individuals from the offspring of prolific ewes, and pay attention to their lactation and nursing performance. Prolific ewes can also be retained based on pedigree.</p><p>Use of prolific genes</p><p>Introducing prolific breeds and crossbreeding them with local breeds is the fastest, most effective and simplest method to improve the reproductive rate of meat sheep.</p><p>Control of breeding technology</p><p>Estrus control: 1. Early weaning of lambs is conducive to implementing the technology of two lambings per year. 2. Hormone treatment. First carry out early weaning of lambs, then treat ewes with progesterone for about 10 days, and after withdrawal inject them with gonadotropin (RMSG), which can induce estrus and ovulation. 3. Use the prostaglandin method. Several days after the end of estrus in ewes, infuse prostaglandin into the uterus or inject it intramuscularly, and the ewes will come into estrus 2 to 3 days after treatment.</p><p>Inducing twin and multiple births: 1. Supplementary feeding to stimulate estrus. Carry out supplementary feeding one month before mating to strengthen body condition and promote estrus. 2. Use twin-lamb stimulant or twinning agent. For the water-based product, inject 1 ml per sheep subcutaneously in the neck 5 weeks and 2 weeks before mating; for the oil-based product, inject 2 ml per sheep intramuscularly in the rump 2 weeks before mating.</p><p>Artificial insemination: adopt advanced insemination techniques to improve the conception rate.</p>

What Are the Reasons Fish Stop Eating? A Full Analysis of Common Causes
Water Quality Problems Water is the environment in which fish live. Water quality can change due to the influence of external natural conditions and human factors. For example, when there are floods, the water color becomes turbid and the water contains much silt, which is unfavorable for the life of fish; too many aquatic plants, or rotting and deteriorating ones, will also

What are the common problems when transplanting muskmelons?
(1) Preparation of the planting site. After the previous crop is harvested, plowing should be done immediately. Because muskmelons require a loose and deep tilth layer, the plowing depth should be 25-30 cm, and should not be shallower than 20 cm. Deep plowing can thicken the loose soil layer, increase soil pores, activate the soil, and

How to remedy problems encountered during mushroom growth?
(1) The mycelium does not grow onto the casing soil layer. This is mainly because the compost is over-fermented or under-fermented, or the pH of the compost and casing soil is improper; or because too much water is sprayed after casing, flowing into the compost layer and causing the mycelium to shrink or die. In cultivation, measures should be taken to strengthen ventilation, adjust the pH, and insert holes into the compost to release excess
