Key Points and Detailed Operation Methods of Lily Whitening Processing Technology
Lily is one of the important health vegetables. The traditional processing method is to blanch the harvested lily and then dry it in the sun. Lily dried by this method still has a relatively high moisture content, is not resistant to storage, and is prone to discoloration. In the past, people used sulfur fumigation to maintain the whiteness of lily, but lily processed by this method is harmful to people's health. Now the dehydration method is used to dry lily, the moisture content is low, and after color protection, blanching and dehydration, discoloration is not likely to occur, which better solves the quality and safety problem of lily caused by sulfur fumigation.

A Detailed Explanation of the Occurrence Patterns and Control Methods of the Jujube Leafroller
The jujube leafroller, also known as the jujube sickle-winged tortrix moth, commonly called the leaf-sticking worm, is one of the important pests of jujube trees. The larvae spin silk to roll leaves for feeding, rolling leaves longitudinally into a dumpling shape, or using silk to bind several leaves together. The larvae also bore into and feed on fruit attached to leaves, greatly affecting yield. 1. Occurrence patterns This pest has 3 generations per year, overwintering as pupae in rough bark crevices on branches and trunks. Adults hide by day and emerge at night, are strongly phototactic, and lay eggs 1 to 2 days after emergence; eggs are mostly scattered on smooth small branches and jujube spurs. The egg stage lasts 10 to 25 days, and the first-generation larvae occur

Fish Domestication Methods: How to Get Fish to Quickly Come to the Feeding Station
In recent years, with the continuous improvement of fish farming technology, the method of raising fish with complete-formula pelleted feed has been gradually promoted and applied. However, because many fish farmers are unskilled at feeding domestication, the domesticated fish are slow to come to the feed station, which not only affects feeding and delays growth, but also increases labor and cost and affects farming profitability. Below are two simple and easy domestication methods we have summarized in production practice. 1. Feed hanging-bag domestication method: Use large-mesh window screening (as long as it does not let feed leak through) to make a
