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 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

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 manage and care for raccoon dogs during pregnancy? These key points are what farmers need to master
I. Feed supply. Many farmers believe that after a female raccoon dog becomes pregnant, the amount of feed and supplements should be increased to boost nutrition. However, years of practical experience have proven that doing so is counterproductive. The correct ration of feed and supplements should be as follows: within 40 days after mating is completed, the feeding frequency should still be once per day, and the feed amount per animal is generally no more than 35 grams of corn flour or complete feed, 20 grams of fish meal, and for eggs, at most 1 egg (about 75 grams) for 5 raccoon dogs. If overfed

Clever inoculation of shiitake mushrooms: master the method to achieve high yields
1. Dense inoculation increases the spawn points on the log segments. More spawn points means a larger area of spawn growth, allowing the mycelium to penetrate deep into the log segments and feed within a shorter time, reducing the chance of contamination by competitor fungi. 2. Deep inoculation: deeper spawn holes hold more spawn, which helps enhance drought resistance and reduces the stimulation of external temperature differences on the spawn blocks at the bottom of the holes. Under constant temperature and humidity, the mycelium inside the spawn blocks germinates quickly, and the survival rate improves. Drilling deeper holes increases the tangential depth of the wood, greatly raising the yield. 3. Early inoculation: under low-temperature conditions, the density and activity of competitor fungi in the air are low,

How to grow licorice seedlings? Master these key seedling cultivation techniques
Choose sandy soil and loam with a low groundwater table and deep soil layer, but it must be irrigated land. When the ground surface temperature reaches 15°C, apply 3000 kg of farmyard manure per mu, plus 40 kg of American diammonium or nitrophosphate, then deep plow 40-50 cm. Deep plowing is essential (otherwise the seedlings grown will have short roots and many branches, mostly failing to meet the specified quality standards). Make a flat seedbed and water once, with the amount of water bringing the soil to the black moisture state (that is, when you grab a handful and throw it down, it does not crumble but holds together like a cake). After three to five days, shallow plow once more, then you can open furrows and sow. Follow the drilling method for seedling cultivation, with a row spacing of 2

Cotton chemical regulation has its finer points: master these technical essentials
In recent years, with the widespread popularization and application of insect-resistant cotton, plastic film mulching and chemical regulation technology, cotton farmers have shown some undesirable cultivation tendencies in cotton cultivation techniques, especially in chemical regulation technology (hereinafter referred to as chemical regulation). Failure to pay attention to timely and appropriately timed chemical regulation leads to excessive vegetative growth and rank growth in cotton fields, over-vigorous vegetative growth, and relatively serious shedding of squares, flowers and bolls, ultimately causing cotton plants to become tall, large and empty, with severe lodging when hit by wind and rain later on, resulting in relatively large losses. During chemical regulation, the goal should be to steadily build a high-yielding framework and increase squares and preserve bolls, mastering the

What to Do About Excessive Cotton Growth Regulator Application? Master These Mitigation Methods
Every year in late July and early August, many cotton farmers in cotton-growing areas report that some cotton plants showed excessive vigor in the earlier stage, and some even tended toward runaway growth, so they applied the plant growth regulator mepiquat chloride. Because they could not get the concentration right, when the spray concentration was too high and they encountered high-temperature weather, the cotton plants showed symptoms of leaves and branches being unable to spread out, and cotton growth was inhibited. Below are several methods to alleviate excessive cotton growth: Spray Huimanfeng active liquid fertilizer. This fertilizer contains chelated humates and multi-element compound fertilizer

How to prevent cotton red leaf stem blight? These integrated measures must be mastered
Cotton red leaf stem blight is a physiological disease. In recent years, it has occurred in large amounts in the cotton region of the Yangtze River Basin in our area. It begins at the early flowering stage, and is more severe and widespread from the full flowering stage to the boll-setting stage. In our area specifically, it occurs sporadically in July and August. It reaches its peak from mid-to-late September to October. Lightly affected plants are yellow and thin, with few and small bolls, short fiber, and poor boll opening; severely affected plants die prematurely, and the bolls cannot mature, greatly affecting yield. 1. Disease symptoms. At the early stage of the disease, red and purple spots appear on the leaves, gradually spreading until the whole leaf turns red
