Cow magnets are popular with dairy farmers and veterinarians to help prevent hardware disease in their cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as hardware disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and reticulum. One magnet works for the life of the cow. These cow magnets also make a great addition to your science project. These magnets are powerful and are great for general experimentation with magnets. There are several kinds of cow magnets: 1) Ceramic cow magnet: This rectangular cow magnet is made of ceramic 5 (strontium ferrite) magnet material; Its special magnetization pattern causes nails and other sharp metal objects to line up along the length of the magnet where they are no longer a danger to the cow; The FDA-approved epoxy coating is gentle on the cow and helps protect the magnet from chipping; Rounded corners ensure safe and easy passage to the reticulum2) AlNiCo 5 cow magnet: A favorite of dairymen and vets for over 30 years; This is the standard cast AlNiCo cow magnet with bright, metal finish; It is non-toxic and non-corrosive in use
Cucumber "flower topping" is a big story
Cucumber flower topping is also known as flower head. It is a common physiological disorder on cucumbers in greenhouses. It usually shows internode shortening near the point of growth. There are no heterozygous flower clusters and no heads forming. shape. Flower topping occurs at the beginning of the results and has a great influence on the yield and quality of cucumber. According to many years of experimental observation, cucumber flower topping can be divided into three types: 1, developmental dysregulation type. The early temperature is low, and the temperature difference between day and night is large. The plants are inhibited by vegetative growth and the reproductive growth is too fast. It is easy to have flowers topping. 2, wound type. High temperatures and droughts in greenhouses, especially when the soil is dry, are caused by too much fertilizer and insufficient water to cause root burning, or the soil is too wet. However, the temperature and the ground temperature are low, causing the roots to easily form a flower topping. 3, physiological deficiency type. Unfavorable soil conditions, weak root activity, and difficulty in attracting fertilizers, can lead to flower topping when physiological deficiency occurs. Prevention methods: (1) Reasonably regulate the temperature, prevent the temperature from being too low or too high; promptly loosen the soil and increase the ground temperature; if necessary, fertilize and water first, then warm up the soil to promote root development. (2) The rational use of fertilizer and water. Greenhouse cucumber fertilization, to master a small amount, multiple times, Shi Liu, the application of organic fertilizer must be fully decomposed, to prevent improper rooting due to improper fertilization. Timely and appropriate watering, to avoid flooding and affecting the ground temperature, resulting in roots. (3) Remedy. Plants with flowering toppings have appeared, female flowers have been removed in appropriate amounts and sprayed with potassium dihydrogen phosphate 300 times; when watering of rooted flowers occurs, watering is done in time so that the water holding capacity of the soil reaches 22%, and the relative humidity of the air reaches When it is 65%, it will be irrigated and will return to normal soon.
