Measures and Methods to Prevent the Occurrence of Three-Molt Silkworms
At present, most of the silkworms reared in our province are four-molt silkworms. Under normal incubation and rearing conditions, a four-molt silkworm should undergo four molts in one generation. However, if the incubation and rearing conditions are poor, a four-molt silkworm may undergo only three molts in one generation, resulting in reduced mulberry leaf consumption, smaller cocoon shape, and lower yield. The reasons why four-molt silkworms undergo only three molts include: incubation under low temperature, dry conditions and darkness at around 20°C; exposure to more than 12 hours of light per day during the young silkworm stage; feeding mulberry leaves that are too tender or too high in protein; after the silkworm eggs are brought back, they are not kept warm and protected, and are directly placed at natural temperature for supplementary incubation, resulting in excessively long supplementary incubation time and accumulated temperature failing to reach the standard;

Three Taboos Beginners in Bonsai Making Must Avoid
1. Never seek out raw material blindly. Many people always want to own a great many bonsai so that they can enjoy them at any time and relieve their "hunger" and "thirst." But when they first begin learning the craft, their appreciation skills are not yet sufficient, so when collecting tree stumps in the wild they grab every stump they see and carry out "carpet-style" digging, which both wastes resources and damages the ecology. When buying at markets they likewise pay no attention to good or bad, superior or inferior, and buy in bulk. The result is mostly crude, substandard pieces that waste time, effort and money. Therefore, although a beginner's eagerness for stumps is understandable, one must have guidance from someone experienced, so as to avoid getting half the result with twice the effort. 2. Growing the stump

Key Technical Points for Three-Dimensional Cultivation of Flower Shiitake in Small Sheds with Large Bags
Flower shiitake has excellent quality and is formed when shiitake mushroom spawn grown on bagged substrate develops under special environmental conditions. It has higher nutritional and commercial value than shiitake, so it is called flower shiitake. Flower shiitake is a rare delicacy in the edible fungi series. High in protein and low in fat, it contains more than a dozen amino acids and various nutrients needed by the human body, has good mouthfeel, a delicious taste, and no pollution; it can also prevent and treat many diseases and has strong disease-resistance effects, so it is called a new anticancer recruit. On the international market, demand exceeds supply. Flower shiitake can be sold fresh or dried for storage, and it is very favorable for both export and domestic sales

Key Technical Points for Diversified Multi-Cropping Three-Dimensional Cultivation of Cotton in the Huaibei Region
Diversified multi-cropping three-dimensional cultivation is a high-yield, high-efficiency agricultural production form and supporting comprehensive technical system that conforms to biological population structure. Developing diversified multi-cropping three-dimensional cultivation can achieve good economic, social and ecological benefits. I. Mechanisms for developing diversified multi-cropping three-dimensional cultivation of cotton in the Huaibei Region. 1. Adapt to local conditions and emphasize efficiency. Three-dimensional cotton cultivation involves multiple crops, multiple factors and multiple disciplines, and is highly time-sensitive, regional, comprehensive and scientific. Therefore, appropriate timing and varieties should be selected for cultivation in combination with the land, climate and other conditions of the Huaibei Region.

Three defenses to do well in winter fish farming management
In winter, the water temperature is low and there is little light, so there is less phytoplankton in the pond water of fish ponds and the oxygen-producing capacity is poor. Because fish feed and move less, their constitution is relatively weak, which has a great impact on safe overwintering and growth. To ensure the safety and growth of fish in winter, the water quality regulation and management of fish ponds in winter should focus on three defenses. Guard against shallow water. Some fish farmers believe that shallow pond water in winter is good for fish, but in fact this is a misunderstanding. In winter, when the pond water level is shallow, the water temperature changes quickly and the temperature difference is large, which will cause freeze damage to fish and is extremely unfavorable to their overwintering and growth. Winter fish ponds

Detailed Guide to Controlling the Three Major Diseases of Onions and Garlic
I. Purple blotch. It mainly affects chives, Welsh onions, garlic, onions, and Chinese chives, and is a major disease of Welsh onions and garlic, with leaves and flower stalks being the main affected parts. The lesions are initially water-soaked, grayish white, slightly sunken, and later expand into oval or spindle shapes, becoming purplish brown. When humidity is high, the diseased area produces black mold layers arranged in concentric rings. In severe cases, it causes leaves and stalks to die or break over. The disease occurs severely under warm, humid conditions or when there is a lack of fertilizer and drought. Fields with sandy soil, dry land, and severe thrips damage have severe disease incidence.

Detailed Explanation of Processing Methods and Techniques for Three Peach Products
Peach preserves. Select white peaches or yellow peaches with firm flesh as raw material. Place fresh peaches into iron frames, put them into a boiling 2%-4% caustic soda solution, and shake for 30-60 seconds. Remove and stir in clean water until the skin completely falls off, then split into two halves along the suture. Remove the pits, rinse in clean water, and after removing the peach pieces and draining the water. Soak in a 0.2%-0.5% sodium bisulfite solution for 2-4 hours to turn the peach flesh milky white. Take 15 kg of clean water, add 22 kg of white granulated sugar, 1 citric acid

How to carve and strip trunk bonsai? Three practical techniques
The trunks of trunk bonsai mostly use the image of being ancient, old, diseased, and disabled to show their "vigorous and sturdy character" that has endured the vicissitudes of time, while some bonsai trees show the characteristics of being young, tender, smooth, and sleek. The carving and stripping technique for trunk bonsai is precisely based on the conditions of the trunk itself, through artificial artistic reconstruction, to make the trunk image conform to the requirements of bonsai artistic modeling and achieve the purpose of enriching the varied texture layers of the trunk. Now let us introduce three techniques of the carving and stripping method. Spiral trunk stripping. Make partial diagonal rotational carving and stripping modeling on the main trunk from bottom to top

How do you make oleander form a "three-fork, nine-top" crown?
Oleander has whorled leaves in threes and is a typical three-fork brancher, meaning that after each pruning, 3 new shoots grow from the stem nodes. People can take advantage of this branching trait to prune and shape it so that it becomes a "three-fork, nine-top" plant. When the main trunk grows to a certain height, pinch off the top, and 3 main branches will grow from the main trunk. When the main branches grow to about 20 cm or more, keep 20 cm on each and pinch off the tops again to make them sprout new shoots. On each main branch, keep another 3 branches, keep 20 cm to 30 cm on each branch, and cut off all the upper branches.
