Bagging Technology for Eggplants and Melons Helps Improve Safety and Efficiency
For vegetables harvested all at once, such as celery, cabbage, Chinese cabbage, and rapeseed, you can follow the pre-harvest interval of the pesticide and stop applying it a certain period before harvest, so the product meets pollution-free requirements. But for eggplant-fruiting and melon vegetables harvested multiple times, it is very difficult to set a fixed period before harvest to stop applying pesticides, especially during the harvest period, when fruits affected by pests or diseases may be harvested and sold before the pesticide residue period has passed, causing quality to decline. In tomato and cucumber cultivation, fruit bagging

What are practical measures to improve pig reproductive efficiency
Breeding pigs are the most fundamental component of pig production. The level of breeding pig reproductive efficiency is affected by many aspects, including breed type, nutrition and feed, feeding management techniques, environmental conditions, breeding techniques, and the health level of the pigs. The economic benefits of a pig farm are inseparable from the level of reproductive performance. The following is a summary of how to improve reproductive efficiency based on current pig production technology. 1 Strengthen feeding management and make full use of the reproductive peak period. Pigs have a relatively long lifespan, but their reproductive years are not long, especially the optimal reproductive stage, which is relatively short.

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
