How to prevent and control jujube fruit shrink disease? A full analysis of the key technical points
Jujube fruit shrink disease is a new disease of jujube trees, often occurring together with anthracnose. When this disease breaks out severely, it causes reduced yields in mild cases and total crop failure in severe cases, and in recent years it has caused huge losses in the jujube-growing areas of our city. The disease mainly damages jujube fruit, causing fruit rot and fruit drop. It occurs during the coloring stage of jujube fruit; in our city it begins in mid-to-late July, and mid-to-late August is the peak period of the disease. Affected jujube fruit first shows a pale yellow halo on the fruit shoulder and body, which then gradually expands into round or irregular water-soaked discolored lesions, with a round brown spot in the center; the flesh in the diseased area

How to grow licorice for high yield? A full breakdown of the technical key points
1. Soil selection. Choose deep soil layers, good drainage, high-lying terrain, and sandy soil and sandy loam soil with relatively high calcium content. Waste flats and waste slopes with slightly alkaline soil and a pH between 7 and 8.5 can all be cultivated. Plots with low-lying terrain and heavy clay soil must not be planted. 2. Variety selection. Choose the new "Wosheng licorice" variety suitable for artificial cultivation. This variety has the following characteristics: First, strong adaptability, drought resistance, cold resistance, salt-alkali resistance, heat tolerance, and tolerance to poor soil. Its temperature adaptation range is 43 to 45°C. In areas with severe water shortage or relatively dry conditions, no wilting or death has been found, and it can adapt to weakly alkaline calcareous soil. At the same time, it is suitable for intercropping with young forest and fruit trees; second, a short growth cycle. With seedling raising and transplanting, the seedlings grow for 3 to 4 months, and after planting they can be harvested after 8 to 10 months of growth; third, fast growth. Because of its prostrate growth habit, combined with artificial cultivation techniques, it grows horizontally at 30 cm on the soil surface, and its absorption rate of natural conditions such as light, water, and fertilizer is high, so its growth speed is fast. Thirty days after sowing, 3 to 4 true leaves appear. At 60 days, the plant height is 30 cm, the root length can reach 20 cm, and the diameter is 0.5 cm; fourth, harvesting and processing are simple. All operations can be mechanized, less labor is used, and it can be sold after being naturally dried to 80 percent; fifth, high yield and good quality. The yield of medium rough grass per mu is more than 500 kg, and high-yielding fields can reach 800 kg. The skin is red, there are few branches, and the strips are uniform. It meets the standards of the national pharmacopoeia and complies with the germplasm requirements for building a GAP production base.

How to prevent and control cotton red leaf stem blight? A full analysis of control measures
I. Symptom identification After the plant is affected, the leaves turn dark green and become thick and brittle, then small red dots are scattered on the leaves, and finally the whole leaf turns red while the veins remain green, which is red leaf stem blight. When the disease is severe, the base of the petiole becomes soft, loses water and shrinks, causing the leaves to wither and fall off, and the top of the stem becomes scorched and dry. At the same time, it easily triggers repeated infection by target spot and brown spot, causing the diseased plant to scorch and die. Some plants can still grow adventitious buds after the diseased leaves fall off. Plants with severe and early onset are short, with poor root development, and both the main root and lateral roots are

What fish preservation techniques are there? A full breakdown of practical methods
1. Wet paper on the eyes. Place soaked paper over the fish's eyes, because behind the nerves inside the fish eye there is a death line, and once this line leaves the water it breaks and the fish dies very quickly. After applying it, the fish can be kept alive for five hours. 2. Hot water soaking. Place the fresh fish in hot water at about 88°C, soak for two minutes, then take it out and put it in the freezer compartment of the refrigerator for quick freezing. Treated this way, the bacteria on the surface of the fish have been scalded to death, and freezing then prevents bacteria from multiplying. After three days, take it out and cook it, and the taste is the same as a freshly killed fish.

What Kind of Fish Is Salmon? A Full Analysis of Origins, Varieties and Characteristics
What is salmon? To answer this question, we must first clarify the origin of the name "salmon." According to research, the Chinese term "sanwenyu" was first proposed in Hong Kong, China and Taiwan, China, as a transliteration of the English name salmon, because the English pronunciation of salmon sounds similar to "sanwen," while the standard Chinese translation of salmon should be "damahayu" or "guiyu." Salmon is not a taxonomic name for fish, but a commercial name for certain salmonid or salmon-trout species. To qualify as salmon, its muscle must be firm and elastic

New upland rice variety developed in Shandong, agronomist Xu Defang successfully breeds it
In the golden autumn season, a new upland rice variety carefully cultivated over 3 years by Xu Defang, an agronomist at the Dongying Branch of the Shandong Academy of Agricultural Sciences, has achieved a bumper harvest. According to calculations, it yields more than double that of the current upland rice variety 297, with a yield of 600-650 kg per mu, marking a breakthrough in China's upland rice breeding. Xu Defang used more than 30 ancestral lines provided by Professor Li Zichao of China Agricultural University, discovered a dwarf-stalk mutant line from the tall-stalk line 33-1, and from it selected a group of 9 lines, namely early-maturing, glutinous, early

How to control the pear yellow gall aphid? A full analysis of effective methods
The pear yellow gall aphid, also called the pear yellow powder insect, attacks only pears and fruit trees of the genus Pyrus. It is tiny: the adult is 0.7 mm long, bright yellow, and obovate, with short 3-segmented antennae, short black legs, and a long mouthpart that even extends beyond the tip of the abdomen; the egg is even smaller, only 0.3 mm long and pale yellow. Adults and nymphs of the pear yellow gall aphid feed in the calyx basin and stem cavity of the fruit. The damaged area of the fruit surface becomes sunken and then turns black and rots, forming cracked large black scars, which lowers fruit quality and causes the fruit to lose part or all of its commercial value. Manual control
