What is the soybean market situation this year? Understanding GM crops in one article
1. So-called genetically modified crops are created by using biotechnology to transfer the genes of certain organisms into other species, modifying the organism's genetic material so that its traits, nutritional quality, consumption quality and other aspects are changed toward goals desired by humans. In China, genetically modified organisms are still relatively rare. So far, only 6 genetically modified crops have been approved for commercialization by the Bioengineering Safety Committee of the Ministry of Agriculture, of which 3 involve crops, namely two kinds of tomatoes and one kind of sweet pepper. 2.

A detailed explanation of the white tea manufacturing process, understanding the whole process in one article
White tea is a specialty of China, mainly produced in Fujian Province. The surface of the dry white tea is densely covered with white downy hairs. The formation of its quality characteristics comes from, first, being made by picking young tender buds and leaves that are rich in downy hairs, and second, from adopting a drying and baking process in production that involves neither pan-firing nor rolling. At present, there are not many types of white tea, divided into bud tea (Baihao Yinzhen, also known as Silver Needle) and leaf tea (such as Gongmei). The production process is simple. The production process of Baihao Yinzhen is: tea buds, withering, baking, screening and sorting, re-firing, packing. The process of Bai Mudan (White Peony) and Gongmei is: fresh leaves, withering, baking (or shade drying), picking and sorting

How Is Yellow Tea Produced? Understanding the Origins of Yellow Tea in One Article
The basic process for green tea is fixation, rolling, and drying. When the green tea processing technique is not properly controlled - for example, if after fixation the leaves are not spread to cool and rolled in time, or after rolling they are not dried or pan-fired in time and are left piled too long - the leaves turn yellow, producing yellow leaves and a yellow brew, similar to the yellow tea that appeared later. Therefore, the emergence of yellow tea evolved from improper green tea processing methods. Xu Cishu of the Ming Dynasty recorded this history of evolution in his "Tea Commentary" (1597).

How to control broad mites in greenhouses and sheds? Understanding the occurrence pattern is key
In greenhouse fruit and vegetable production, curled and shrunken growing points of plants, deformed and cracked fruits are often seen, causing serious losses to production. Because the temperature and humidity inside the greenhouse are very suitable for the growth and reproduction of broad mites, and fruit vegetables are their main targets, and the mites are extremely small and invisible to people, timely control is impossible. Therefore, in recent years, the area of occurrence and damage has been growing larger and larger, which should attract great attention from producers. Broad mites belong to the class Arachnida, order Acariformes, family Tarsonemidae, and are harmful microscopic pests. They mainly damage cucumbers, eggplants, and tomatoes among greenhouse vegetables.
