Technical key points for restoring tea production after snow disaster and freezing damage to tea plants
This year, some tea regions across the country experienced severe weather such as heavy snow and low-temperature freezing that had not occurred in decades, causing tea branches to break, leaves to discolor and dry up, and branches to die, resulting in varying degrees of snow disaster and freezing damage. In order to restore tea production as quickly as possible and reduce the economic losses of tea farmers, the following technical key points are proposed according to the disaster conditions. 1. Pruning 1. Mild freezing damage (only leaves damaged): do not prune or lightly prune as appropriate. 2. Moderate freezing damage (production branches damaged) and severe freezing damage (framework branches damaged): prune when the boundary between the frozen-dead part and the healthy part is clear,

Technical Service Information for Tea Plant Frost Resistance and Post-Disaster Recovery
I. Remedial measures for tea plants after a disaster: 1. Scientific pruning: Because tea gardens with different varieties, different altitudes, and different slope aspects have different degrees of frost damage to their tea plants, generally tea gardens with large-leaf varieties, high altitude, and north-facing slopes suffer more severe frost damage to the tea plants. Timely and reasonable pruning should be carried out according to the degree of frost damage. After the temperature rises and stabilizes, observe the frost damage to the tea plants. For lighter frost damage, use light pruning, that is, cut about 3 cm below the leaf surface. For more severe frost damage, carry out deep pruning, cutting off 1/2-1/3 of the plant. For particularly severe frost damage

Guidelines for Fishery Reconstruction Measures After Rain, Snow and Freezing Disasters in Southern China
Since early January 2008, rain, snow and freezing weather has severely affected fishery production in multiple provinces and municipalities in southern China. According to incomplete statistics, losses from fish and shrimp killed by freezing in southern provinces and regions exceeded 10 billion yuan. In response, the following measures and suggestions for freshwater fishery reconstruction after rain, snow and freezing disasters in southern regions are proposed for reference. In terms of aquaculture species and regions, the current damage is mainly divided into the following types: 1. Tilapia aquaculture: The tilapia aquaculture industry suffered the most severe losses during this winter's cold wave.

How should cotton be managed after suffering a hail disaster?
Timely drainage to prevent waterlogging. Hail is often accompanied by violent wind and rain, which frequently causes water to accumulate in the fields; when soil moisture is too high, it easily damages cotton roots and affects the normal growth of cotton. After a hail disaster, trenches should be cleared and drainage carried out immediately to reduce humidity. Intertillage and loosening the soil. After a hail disaster, the cotton field soil becomes compacted, with low ground temperature and high humidity. All types of hail-affected cotton fields should be intertilled and loosened in a timely manner to break up compaction, raise ground temperature, promote root physiological activity, and help the cotton plants return to normal growth as quickly as possible. For severely damaged cotton fields where more than 80% of the cotton plants have bare stalks after the hail disaster, it is recommended to pull up the cotton plants and replant other crops, so as to minimize

What to Do When Cotton Is Killed by Rainwater? A Detailed Guide to Post-Disaster Remedial Measures
Drain waterlogging and clear silted ditches in time. After a cotton field is flooded, the soil's physical and chemical properties change, humidity becomes too high, and air is lacking, which can suffocate the cotton plants to death. Even if they do not die, they are prone to disease, and root penetration is hindered. The waterlogging must be drained as quickly as possible, and at the same time the clogged perimeter ditches, waist ditches and bed ditches should be cleared to lower the groundwater level and create a good ecological environment for the cotton seedlings so they can resume growth. Straighten and wash the seedlings in time, washing them as the water recedes. Clean the silt off the cotton leaves and stems so the leaves can quickly recover

What production management measures should be taken for edible fungi after a rain disaster?
(1) Harvest promptly to reduce losses. Although it is now the late stage of the black fungus arrangement phase, there is still some yield and income. Wait until the weather clears, then harvest all the black fungus, remove the moldy and rotten ones, rinse the good fungus clean with water, and then sun-dry them to reduce losses. (2) Promptly turn and sun-dry the raw and auxiliary materials for edible fungi. If the raw materials and auxiliary materials used for edible fungus production this year have been soaked with water, they must be immediately turned and sun-dried after the flood to prevent the raw materials from becoming moldy. (3) Promptly clear ditches and drain water. If the black fungus arrangement field is flooded or washed by large water, promptly carry out the black fungus cultivation

Key Technical Points for Disaster Resistance and Mitigation and Spring Management of Edible Fungi
1. Clear away ice and snow, dig ditches for drainage. Promptly remove accumulated ice and snow from the top and surroundings of mushroom sheds (houses) to prevent them from collapsing. Dig drainage ditches around the mushroom sheds (houses) to keep drainage smooth and avoid rain and snowmelt attacking the mushroom substrate. 2. Stop spraying water and keep the substrate surface as dry as possible. Because at low temperatures the mycelium of edible fungi enters a dormant state, and spraying water can easily cause death. 3. Strengthen heat preservation management of mushroom sheds (houses). Small arched tunnels can be set up inside the greenhouse, and coverings such as plastic film and straw curtains can be added outside the shed for insulation and dehumidification. Use plastic

Remedial and Management Measures for Fishery Production After a Disaster
Recently, in some areas of our province, continuous heavy rains caused many aquaculture ponds to overflow and fish to escape, bringing relatively large losses to farmers. Doing a good job of remedial and management work for fishery production after the disaster has become an important task for aquaculture farmers at present. Based on years of experience in fishery work, the author proposes the following measures for the reference of the broad community of farmers. 1. Remedial measures for fishery production after a disaster. 1. Surround the fish pond with netting. When floodwaters recede, surround the fish pond with netting at the appropriate time to prevent fish in the pond from continuing to escape, thereby reducing losses. 2. Restock fry and fingerlings

Agricultural drones have wide applications, excelling at spraying, fertilizing and disaster surveying
Nowadays drones are being used more and more widely, and they are also used in agriculture. Let's take a look together. Unmanned aerial vehicles are seen as a promising new capable assistant for the future development of agriculture. Not only has the Civil Aeronautics Administration been busy drafting regulations, under which anything above 250 grams will in future require real-name registration, but all sectors are also actively investing in developing agricultural and other uses of drones. The Agricultural Research Institute of the Council of Agriculture, Executive Yuan, has set up a drone team and is currently building experimental data; in future it is expected to establish a set of operating manuals for farmers to refer to.

What protections does agricultural major disaster insurance offer? Building agricultural occupational disaster protection is imperative
Farmers themselves lack awareness of occupational safety, and when an accident happens they also lack occupational disaster insurance claims; afraid that the crops will not be harvested in time, they grit their teeth and keep farming despite illness and pain. Compared with other industries, is agriculture actually high-risk? Is there a legal basis to protect the occupational safety of those who work in farming?
