Cotton topping must be done at the right time and promptly; seizing the moment is key
Cotton has an indeterminate growth habit. Under certain temperature conditions, the terminal bud keeps growing and extending, and continuously differentiates new stems, leaves and fruiting branches. Topping is the manual removal of the terminal bud so that it no longer produces new fruiting branches, allowing the vast majority of bolls to open before frost. Therefore, this is a key operation for artificially regulating the cotton growth period. Before topping, the cotton plant has apical dominance, with water and nutrients supplied preferentially to the terminal bud; after topping, they are supplied preferentially to the organs growing and developing fastest. It can thus be seen that topping affects the transport and distribution of nutrients in the cotton plant, so

Licorice should not be stored for too long; the storage time of medicinal materials must be reasonably controlled
Licorice is generally stored as compressed bales wrapped in burlap, each weighing 50 kg, kept in a dry, ventilated place, with a safe moisture content of 12%-14% for the commodity. There are more than ten kinds of warehouse pests of licorice, including the coffee bean weevil, the brown mulberry borer, and the four-spotted chestnut borer. Fumigation with nitrogen or carbon dioxide for 514 hours can kill all adults and larvae, with no obvious change in the inner quality of licorice. Licorice is prone to mildew. If the air humidity is too high, mold spots or white and green mycelium easily appear on the surface of licorice. The following measures can be taken for prevention and control

Timely Maintenance and Repair of Agricultural Machinery After Wheat Harvest
Combine harvesters should be well maintained before heading to the field, so that they stay in good technical condition, run with fewer breakdowns, perform reliably, reduce faults, improve work efficiency, and extend service life. 1. Self-propelled combine harvesters (l) Add lubricating oil to each lubrication point daily as specified. (2) After a period of use, tighten the front wheel and rear wheel nuts; check and adjust the tension of all V-belts; check and adjust all drive chains; when the indicator light comes on, clean the dry air filter; clean the rotating wind hood and radiator; check the coolant level and top it up; check and clean the water collector; check the fuel filter, drain the accumulated water and sediment, clean the hydraulic oil tank filler port and check the oil level. Park the combine harvester on level ground, check the engine oil in the oil pan, and add oil as needed; tighten the grain unloading auger wire rope; clean the hydraulic drive oil tank filler port and check the oil level. If necessary, clean the cab filter. (3) After one quarter of use, replace the fuel filter element and replace the engine oil filter. Check the specific gravity of the battery electrolyte, and charge or top up with distilled water as needed. Check the coolant level and top it up. Clean the fuel transfer pump, check and adjust the traveling clutch clearance, check and adjust the foot brake, and adjust the hand brake cable.

What is the best mating time for dogs
The mating period for female dogs is generally 8-10 months after birth, while for male dogs it is about two years or one year and one month after birth. There are exceptions, such as male wolf dogs, which should mate only after reaching two full years of age, while females do better after reaching one and a half years. The mating period for male dogs is 2-3 months later than that of female dogs. Saint Bernards and Danish wolf dogs do not enter their mating period until they have fully become large dogs. However, there are also occasional cases in which a young dog suddenly runs out of the kennel and does not return, and by the time it comes back it is already pregnant, so for 1-year-old female dogs, special

What is the best time to collect rabbit skins?
① Collect skins by age in months. At around 6 months of age, the second molt has ended and the fur enters its growth and maturation stage; the hair roots are firmly seated and not easily shed. At the same time, the skin board has basically matured, with good flexibility, toughness and elasticity, and the skin board area has also reached the grading standard. Therefore, collecting skins at 6 to 8 months of age is best, and can improve the grade and economic value of the rabbit skin. ② Collect skins by season. Collecting skins from the end of December to before the end of March of the following year is the best season for obtaining high-grade rabbit skins.

Harvest Time and Processing Methods for Licorice
The harvest time is generally late autumn to early spring, and it is best after the leaves have fallen and withered in autumn. The licorice roots harvested at this time are firm in texture, heavy in weight, high in powder content, and strong in sweetness. Remove the soil from the dug-up licorice (washing with water is strictly prohibited). While still fresh, use a fodder chopper or a sharp knife to cut off the branch roots from the head and root portions close to the main root. Divide them into first and second grades according to the diameter of the root head, and mao cao. Generally, dried goods with a thick head diameter of more than 1.5 cm are first grade, those with a diameter of 0.3-1.4 cm are second grade, and those smaller than 0.5 cm are placed in mao cao. For first and second grade licorice, the root strips must not be shorter than

Emergency treatment for cattle bloating, farmers must master it in time
Causes of bloating There are three main causes of bloating in cattle: 1. Eating green plants containing too much water and soluble protein. 2. Overeating grain feed and forage, which accelerates the decomposition of fatty acids, lowers the alkalinity in the rumen, and leads to acid accumulation. 3. Mechanical obstruction of the esophagus, which hinders belching. Bloating in farm cattle is generally not difficult to diagnose; the difficulty lies in how sudden the onset is, and often there is no time to find a veterinarian for diagnosis and treatment before death occurs in 1 to 2 hours. Emergency measures 1. Pure ichthammol 150 to

How to control the Euonymus leafroller moth at the right time?
The Euonymus leafroller moth, also known as the Euonymus moth, is one of the earlier leaf-eating pests to harm garden plants. After several years of observation, the author found that in the Xi'an area its larvae appear in late March, mainly harming plants such as Euonymus japonicus (evergreen euonymus), Euonymus bungeanus (winterberry euonymus), and Euonymus fortunei (climbing euonymus). In severe cases they eat all the leaves, affecting the ornamental effect. When low-instar larvae are found causing damage, spray evenly with 50% phoxim emulsifiable concentrate or 40% omethoate emulsifiable concentrate at 1000 times dilution, or with 2.5 deltamethrin emulsifiable concentrate at 2000 times dilution; the control effect is very good.

Garlic sowing time should not be advanced; mastering the right sowing time is key
Garlic prefers cool conditions and has a dormant characteristic. If sown too early, the emergence time is prolonged, and after emergence the temperature cannot drop, so the leaves tend to turn yellow and form weak seedlings, ultimately affecting quality and yield. If sown too late, before overwintering the seedlings are small and have weak cold resistance, and the following year they easily form large-headed garlic. By summarizing the experience of growers and the author's trials, it is recommended that garlic in our province be sown in late September. At this time the garlic dormancy period has passed, and 13 days after sowing the seedlings can emerge uniformly. After emergence, the seedlings are in the cool autumn season, which is favorable for their growth, and before overwintering they can grow enough 6 leaves, with enhanced cold resistance.
