Scientific feeding is essential in soft-shelled turtle hatchling rearing, and mastering the method is key
affects the farming of adult soft-shelled turtles. Whether scientific feeding can be carried out is the technical key affecting the growth and quality of soft-shelled turtle hatchlings. For this reason, here is an introduction to scientific feeding in soft-shelled turtle hatchling rearing, for reference and application. As with farming other aquatic animals, feeding can follow the four-fixed principle, namely fixed quality, fixed quantity, fixed time and fixed location. However, the four-fixed contents of feeding in soft-shelled turtle hatchling rearing have their own characteristics. Because soft-shelled turtle hatchlings, during their growth process, not only need to accumulate energy and increase body weight, but also need to provide various nutrients and

How to prevent pica in sheep? Sheep farmers need to master these methods
1. According to the nutritional needs of sheep at different growth and production stages, supply the necessary amounts of energy, protein, minerals (calcium, phosphorus, sodium, potassium, sulfur), trace elements (zinc, copper, iron, cobalt, etc.) and vitamins (A, D, E), and feed a compound diet to ensure comprehensive, scientific and rational nutrients. Ensure that sheep can drink enough water. For high-yielding sheep and pregnant ewes, attention should be paid to the provision of calcium feed. 2. Feeding should be at fixed times, in fixed amounts, and by a fixed keeper, and do not feed frozen or moldy feed. In winter and spring

How to manage cotton during the squaring stage? These key points you need to master
The cotton squaring stage is an important turning point in the life of the cotton plant. During this period, vegetative growth and reproductive growth proceed simultaneously, with vegetative growth predominating. Production management should, on the basis of strong seedlings and early development, adopt reasonable measures to promote and control growth, so as to achieve steady plant development and build a good framework for a high yield. The technical key points are: 1. Continue to do a good job of digging drainage ditches to prevent both surface waterlogging and subsurface waterlogging. 2. Intertill and earth up to promote the development of the cotton root system. 3. Prune in a timely manner. Hybrid cotton has vigorous vegetative growth, with more leaf branches and superfluous buds. Depending on the field planting density, it is advisable to keep 1-2 leaf branches per plant,

How should cotton be managed after suffering a hail disaster?
Timely drainage to prevent waterlogging. Hail is often accompanied by violent wind and rain, which frequently causes water to accumulate in the fields; when soil moisture is too high, it easily damages cotton roots and affects the normal growth of cotton. After a hail disaster, trenches should be cleared and drainage carried out immediately to reduce humidity. Intertillage and loosening the soil. After a hail disaster, the cotton field soil becomes compacted, with low ground temperature and high humidity. All types of hail-affected cotton fields should be intertilled and loosened in a timely manner to break up compaction, raise ground temperature, promote root physiological activity, and help the cotton plants return to normal growth as quickly as possible. For severely damaged cotton fields where more than 80% of the cotton plants have bare stalks after the hail disaster, it is recommended to pull up the cotton plants and replant other crops, so as to minimize

What to Do When Cotton Is Killed by Rainwater? A Detailed Guide to Post-Disaster Remedial Measures
Drain waterlogging and clear silted ditches in time. After a cotton field is flooded, the soil's physical and chemical properties change, humidity becomes too high, and air is lacking, which can suffocate the cotton plants to death. Even if they do not die, they are prone to disease, and root penetration is hindered. The waterlogging must be drained as quickly as possible, and at the same time the clogged perimeter ditches, waist ditches and bed ditches should be cleared to lower the groundwater level and create a good ecological environment for the cotton seedlings so they can resume growth. Straighten and wash the seedlings in time, washing them as the water recedes. Clean the silt off the cotton leaves and stems so the leaves can quickly recover

How to prevent cotton diseases? Mastering these techniques is key
In recent years, the harm caused by diseases has become one of the important factors restricting cotton yield and quality. For some diseases, the symptoms are not obvious at the beginning and are easily overlooked, and by the time they become severe, it is too late to take measures. Especially in continuous cropping plots, cotton farmers find some commonly occurring diseases and soil-borne diseases very troublesome, and often feel helpless. For this reason, when it comes to cotton diseases, the approach should be "prevention first, treatment second." There are quite a few cotton diseases, but the two that give cotton farmers the biggest headache are mainly these: first, the problem of dead seedlings caused by damping-off disease after emergence, and second, verticillium wilt and fusarium wilt.

Licorice is not difficult to grow; master the method and you can grow it well.
At present, there is great demand for licorice products in domestic and international markets. Experts believe that to resolve the contradiction between the demand for licorice products and environmental protection, the most critical thing is to develop the artificial cultivation industry of licorice. From the current actual situation of artificial licorice cultivation, promoting the coordinated progress of planting and fenced breeding, and rationally developing the path of base construction, is practical and feasible. In fact, licorice is not a difficult plant to grow; as long as the soil and moisture are suitable, it can be planted on a large scale. Some people believe that the key to solving the problem of artificially cultivating licorice is now mainly not funding.

How to increase the yield of spring-planted shiitake mushrooms? Master these tips for high yields
Raise the temperature of the mushroom bed to create conditions for mushroom growth. Since the mushroom yard is still cold in early spring, natural air temperature can be used together with artificial regulation. The method is: cover the film tightly to increase the ground temperature, and at the same time choose sunny days to spread the shading materials on the shed surface thinly, letting sunlight penetrate into the mushroom yard, increasing the heat source and raising the mushroom bed temperature; at night, cover the film tightly to protect against the cold. The large day-night temperature difference in early spring can promote the occurrence of mushroom buds. Pat the mushroom logs to promote the recovery of mycelial growth. Because the climate is cold in early spring, the mycelium is mostly in a dormant state, producing no mushrooms or very few mushrooms. Generally, patting can be used

How to grow potted oleander? Master these care essentials
Oleander, also known as willow-leaf peach and half-year red, is an evergreen large shrub of the genus Nerium in the dogbane family Apocynaceae.
