What should be noted when mixing chicken daily rations?
There are many kinds of chicken feed; which feed should be the main one? How can it be mixed scientifically and rationally while also being low in price? 1. First, you must understand what nutrients the chickens you raise need. Because the requirements of various chickens differ, such as light-layer chickens, heavy-layer chickens, or meat chickens, chicks, older chickens, or breeding chickens, the nutrients needed by various chickens are not completely the same in quantity and quality. Chicken farmers should consult the corresponding materials according to chicken breed and size to determine the required nutrients. 2. You need to know which type of feed produced locally is more abundant and lower in price

What issues should be noted in the efficient cultivation of kernel apricots?
Kernel apricot is one of the main dried fruits in northern China, with excellent economic returns. In recent years, due to the development of almonds, the comparative benefit of kernel apricots has somewhat declined. To improve the production efficiency of kernel apricots, comprehensive measures should be adopted. 1) Develop in suitable sites. Kernel apricots are drought-tolerant, tolerant of poor soil, and widely adaptable, but for efficient production, orchards must be established in locations with deep soil layers, fertile soil, and sheltered, south-facing slopes. Because kernel apricots bloom early and are susceptible to late frost damage, avoid establishing orchards on mountain ridges, wind gaps, and low-lying areas. 2) Pay attention to configuring pollinizer trees.

What technical points should be noted when introducing tea plants?
Tea plant introduction is simple and easy to achieve results. Since the 1950s, the area planted with improved varieties has been expanded. For example, the Yunnan large-leaf variety was introduced to Guangdong, Guangxi, Sichuan, Guizhou and other provinces and autonomous regions, and the area has reached more than 1 million mu. Fujian, Zhejiang and other provinces used introduced and acclimatized Yunnan large-leaf varieties as original material to breed a group of excellent high-yield new varieties. New progress has been made in introducing tea from the south to the north. The northernmost boundary of tea plant distribution in China has shifted from about 34°40'N to near 37°49'N, advancing northward by more than 350 km. Tea varieties have also been introduced successively from the former Soviet Union, Ja

What key points should be noted for late-planted rice when transplanting into fields prepared with stored water?
The general requirement for transplanting late-planted rice into fields prepared with stored water is to seize the water, prepare the field, and transplant the seedlings, increasing the number of hills, seedlings, and panicles. For rice fields transplanted with stored water, as soon as rainfall occurs or another water source becomes available, measures such as blocking, diverting, and pumping water should be taken immediately to seize the water, prepare the field, and transplant the seedlings. For late-planted fields, planting density should be increased. For seedlings aged 60-70 days, transplant more than 13,000 hills per mu (8 x 6 cun), with two seedlings per hill (2 grains of rice); for seedlings aged over 70 days, transplant more than 15,000 hills per mu (8 x 5 cun), with about 10 seedlings per hill, so that the number of seedlings planted per mu reaches 150,000

What technical points should be noted for indoor cultivation of oyster mushrooms?
Oyster mushrooms are welcomed by people for their delicious taste, short production cycle and ease of cultivation. Especially in Northeast China, where the climate is cold in winter and spring and fresh vegetables are scarce, growing oyster mushrooms indoors to supply the market is truly a good way to make money. However, a prominent problem in indoor cultivation of oyster mushrooms is that the air temperature is not easy to control and the surface layer of the substrate dries out easily, affecting oyster mushroom production. After repeated trials, the author believes that casing soil cultivation gives good results. 1. Mushroom house selection. Abandoned or temporarily unused houses can be chosen as the mushroom house (they must be repainted with limewater), and heating and ventilation facilities are required.

What should be noted in mechanized potato harvesting
When harvesting potatoes mechanically, in order to save time, labor and effort, improve the economic benefits of machine use and the marketable rate of potatoes, the following issues should be noted. (1) About 10 days before the determined harvest date, the vines should first be rolled or cut (the method of rolling vines is to thread old tires onto an axle in a string and pull them with a tractor to roll the vines), so that the potato skins age and are prevented from being damaged during harvest, which would affect the quality of marketable potatoes. (2) The number of potato pickers matched to each machine unit should be reasonable. Small harvesters are generally matched with

What should be noted when growing Gastrodia elata in boxes?
① You must choose high-quality fungus logs, preferably those with many young rhizomorphs distributed evenly. ② The fungus logs must be free of contamination by other fungi. ③ If there are not many rhizomorphs on the fungus logs, you may appropriately add some fungus branches or secondary or tertiary solid spawn of Armillaria mellea. You can also cover the fungus logs with a layer of culture substrate for cultivating Armillaria mellea (because the substrate contains Armillaria mellea, which acts as spawn). ④ If a piece of fungus wood is placed parallel 3 cm beside a high-quality fungus log, once the fungus wood connects with and grows Armillaria mellea well in the later stage, it can continuously supply nutrients to Gastrodia elata. But do not plant the Gastrodia near the fungus wood

What should be noted when herding ducks in spring?
Choose good grazing grounds. During spring plowing, in rice-growing areas, ducks can be grazed in green manure fields that have been plowed and are being prepared for transplanting rice seedlings. Such fields contain plenty of natural plant and animal feed, such as grass seeds, grass roots, earthworms, and insects. After the rice seedlings are transplanted, ducks should not be taken into the fields to graze; grazing can resume only after the rice is harvested. Graze carefully. In river network areas, make full use of river channels for grazing. Generally, when taking the ducks out to graze, it is better to go upstream, when the ducks are full of energy and catch more food. In the cold spring season, when windy weather occurs, graze against the wind to prevent the wind from lifting the ducks' feathers and causing them to lose too much body heat. In areas with abundant feed

What issues should be noted during the processing of yellow peaches?
Influenced by international yellow peach market prices, domestic yellow peach prices have been climbing steadily, with purchase prices maintained at 2-3.6 yuan/kg, an average price of 2.6 yuan/kg, and average output value of yellow peach orchards at 7800 yuan/mu, with the highest reaching 10,000 yuan, generally 2-5 times that of ordinary peach orchards, showing very significant economic benefits. 1. Pay attention to selecting excellent varieties: Yellow peach varieties used for canning require non-melting flesh, firm texture, good elasticity, low juice content, clingstone, no red streaks in the flesh, and preferably no
