How to control wheat aphids? Three measures to improve control effectiveness
Wheat aphids are one of the main pests currently harming wheat. In recent years, due to changes in climatic conditions, a decrease in the number of natural enemies, and improper control measures in wheat fields, the harm caused by wheat aphids has become increasingly serious, resulting in reduced wheat yield and declining quality. In response to farmers' situations in controlling wheat aphids, taking the following three measures can improve the control effectiveness of wheat aphids. Determine whether to control based on the control threshold. The control threshold for wheat aphids is 500 aphids per 100 ears. As long as a field reaches the control threshold, pesticide control should be applied immediately. Controlling according to the control threshold not

Detailed Explanation of the Biological Characteristics of Angelica sinensis (Part Three)
(1) Bolting and flowering. Angelica sinensis is a monocarpic plant. Under normal cultivation conditions, it enters the bolting and flowering stage in the third year. About half a month after the plant turns green again, the growing point begins to shift from the vegetative growth state to the reproductive growth state, forming a reproductive growing point, and some protrusions gradually appear at its apex, namely the inflorescence primordia. As the inflorescence primordia elongate and grow, the tip of each primordium begins to widen and produces several small protrusions, namely the umbellule primordia. After the umbellule primordia elongate, they form the rudiment of a compound umbel. At the same time, the basal stem swells and lengthens, forming internodes and constituting

Six-Part Series on Autumn Mushroom Production, Part Three
3. Disinfection and treatment of new mushroom sheds, establishing the concept of "prevention": this means emphasizing the prevention principle of "prevention first, combining prevention and treatment." Inside the shed, drugs such as Baibing Quwuzong and phoxim can be used. The general dosage is 1 bag of Baibing Quwuzong mixed with 50 grams of phoxim, sprayed over about 30 sq m. The targets of application are the ground, walls, and support columns, etc., and carpet-style spraying is required. Then seal the mushroom shed, roll up the grass mats to sun the shed, and after 2 days of sealing, bags can be brought in for spawn running or fruiting; for preventive medication during spawn running and fruiting, spray mushroom

How to prevent and treat paralysis in sows? These three methods are very practical
Paralysis in sows is a metabolic disease that is extremely likely to occur under conditions such as extensive feeding management and poor feed conditions. Once the disease occurs, it not only affects the sow's value for use, but also affects the quality of the piglets, causing great losses to production. Based on many years of clinical experience, the author achieved satisfactory results in treating sow paralysis by combining Chinese and Western medicines with acupuncture. It is introduced below for the reference of readers. I. Causes of the disease This disease mainly occurs after farrowing and during lactation in sows. The former is due to

Key technical points for preventing five hazards and protecting three types of seedlings in cotton seedling beds
Common problems in cotton nutrient bowl seedling beds are mainly manifested as drought, waterlogging, disease, fertilizer, pesticide and frozen seedlings, burned seedlings, and spindly seedlings. 1. Prevent the "five hazards" 1. The water content in the bowls should be moderate. The nutrient bowl seedling bed should be selected in a place convenient for both drainage and irrigation. The water content in the bowls is best when the soil can be pinched into a ball by hand and falls apart upon hitting the ground; 2. After sowing cotton and covering with soil. Water thoroughly in one application, and water until it slowly infiltrates downward; 3. After covering with film, ensure sufficient soil moisture. Do not uncover the film at will, and do not uncover the film until the seedlings emerge completely; 4. Around the seedling bed, drain surface water and filter waterlogged water
