How should the four common bean diseases be prevented and controlled?
1. Root drowning: Beans prefer moisture and tolerate drought but not waterlogging. Therefore, on the basis of ridge cultivation, small amounts of water should be applied to avoid water accumulation in the field, which prevents the roots from breathing and causes plant death. Control measures: Avoid flood irrigation. If there is heavy rain, drain the water promptly. After the weather clears, if conditions permit, appropriate shallow hoeing can be done to increase soil permeability and improve root vitality. 2. Phytophthora blight: It mainly damages the stems and vines, and sometimes the leaves and pods are also affected. It constricts at the base of the stem, causing the upper part to wilt and die. When humidity is high, white mycelium is produced on the diseased part.

Detailed Explanation of Silicon Window Controlled Atmosphere Storage Technology for Garlic Scapes
In the early 1980s, China began large-scale promotion of silicon window controlled atmosphere technology to preserve garlic scapes. It works by embedding a certain area of silicone rubber membrane in a plastic bag to automatically regulate the gas composition inside the bag, achieving the purpose of preservation. It has the characteristics of saving labor, saving time, saving energy, convenient management, stable gas composition, long storage period, low loss, and good quality. The economic benefits are significant, so it was promoted and used on a large scale in a short time. I. Silicon Window Controlled Atmosphere Storage of Garlic Scapes 1. Forms of Silicon Window Use Cold storage silicon window controlled atmosphere has two forms: small packaging fresh-keeping bags and large plastic tents.
